OBJECTIVE:Evaluate the clinical competency in detection and management complicated pneumonia, diarrhea, and measles cases of trainees who were village doctors in Puer city of Yunnan province, China.MATERIAL AND METHOD:One hundred fifty four village doctors working in the border areas were trainedfor 5-day Integrated Management of Childhood Illness (IMCI) training, which was adapted to World Health Organization (WHO) guidelines. Pre- and post-training assessment based on a modified WHO package was carried out.RESULTS:Statistically significant improvements in almost allperformances were observed. However, the level of post-training achievement was still low. Correct classifications of severe pneumonia, measles, and diarrhea were found in 63.0% 54.3% and 83.5%, respectively in the post-training periodCONCLUSION:The training package needs to be further strengthened.
Objective To investigate the prevalence,epidemiology and clinical features of Human Bocavirus(HBoV)and Human Metapneumovirus(hMPV)infection in children with respiratory tract infection in Kunming.Methods From October 2009 to December 2010,550 nasal swab samples were collected from children under 5 years with respiratory tract infection.Multiplex polymerase chain reaction was used to detect 21 common pathogens including HBoV and hMPV.At the same time,the baseline characteristics of children and clinical manifestation were recorded by researchers through structure questionnaire.SPSS software was used to analyze data.Results Out of 550 nasopharyngeal swab specimens,18 specimens were detected with HBoV infection and 29 samples were detected with hMPV infection.The positive rate of HBoV and hMPV was 3.3% and 5.3%,respectively.Among 18 HBoV positive samples,there were 17 samples mixed other pathogen infection.The mixed infection rate of HBoV accounted for 94.4%.Meanwhile,among 29 hMPV positive specimens,the co-infection rate was 58.6%.The most common pathogens of mixed infection with HBoV and hMPV were respiratory syncytial virus,rhinovirus,influenza A virus and Haemophilus influenza.Infant got higher HBoV infection.There was no significant difference between different age groups of hMPV infection.The peak of positive infection rate of HBoV and hMPV were both in autumn and winter.Fever,cough and wheezing were the major clinical manifestation of children with HBoV and hMPV infection.Conclusions HBoV and hMPV are important pathogens of acute respiratory tract infection in children in Kunming.The prevalent seasons are autumn and winter for the two virus infection.
BACKGROUND:Under-5-years child mortality remains high in rural China. Integrated management of childhood illness (IMCI) was introduced to China in 1998, but only a few rural areas have been included. This study aimed at assessing the current situation of the health system of rural health care and evaluating the clinical competency of village doctors in management of childhood illnesses prior to implementing IMCI programme in remote border rural areas.METHODS:The study was carried out in the border areas of Puer prefecture of Yunnan province. There were 182 village doctors in the list of the health bureau in these border areas. Of these, 154 (84.6%) were recruited into the study. The local health system components were investigated using a qualitative approach and analyzed with triangulation of information from different sources. The clinical component was assessed objectively and quantitatively presented using descriptive statistics.RESULTS:The study found that the New Rural Cooperative Medical Scheme (NRCMS) coordinated the health insurance system and the provider service through 3 tiers: village doctor, township and county hospitals. The 30 RMB per person per year premium did not cover the referral cost, and thereby decreased the number of referrals. In contrast to available treatment facilities and drug supply, the level of basic medical education of village doctors and township doctors was low. Discontent among village doctors was common, especially concerning low rates of return from the service, exceptions being procedures such as injections, which in fact may create moral hazards to the patients. Direct observation on the assessment and management of paediatric patients by village doctors revealed inadequate history taking and physical examination, inability to detect potentially serious complications, overprescription of injection and antibiotics, and underprescription of oral rehydration salts and poor quality of counseling.CONCLUSION:There is a need to improve health finance and clinical competency of the village doctors in the study area.
Objective To learn health HR status quo of front-line village clinics in the border of four counties,such as: Lancang,Ximeng,Menglian and Jiangchen in Puer.For exploring country health workers training model which is suited in minority nationality regions.Methods We do the questionnaire surveys to all registered health workers in 20 border townships in above four counties by WHO investigation methods and relevance questionnaire data.Results There are 87 village clinics and 137 village health workers.The average is 1.57 country health workers per village,94% of them are minority nationality health workers,village health workers sex ratio is 1.45:1.Most of them are graduated from the middle school and health school.Average age is 34 years old.Their medical professional level is low,especially to children’s disease and prevention health care.Conclusions The number of health workers are satisfied the requirement in front-line village clinics in Puer of Yunnan province.Age structure and sex ratio are reasonable.The gaps of their medical professional level is large,and the low education background has not be solved too.It’s necessary that the health workers professional training should be expanded and strengthened.
Objective To observe efficacy and safety of traditional Chinese medicine in Yunnan-GanMaoXiaoYan tablets in treatment of children with influenza A(H1N1)infection.Methods According to the case inclusion criteria,we collected influenza A(H1N1)suspected cases and randomly divided them into treatment group and control group.Patients in treatment group and control group were given treatment drug and control drug,respectively.We detailedly recorded the clinical information,collected nasal swabs before and after treatment and continuously followed up with real-time RT-PCR on nasal swabs for pathogen detection.Results The thermal annealing time(h)of patients in treatment group and control group was 13.09±7.02,and 22.13± 15.55(P<0.05),respectively.The sore throat relief time(h)was 20.36±7.91 and 27.20±12.30(P<0.05),respectively.The cough relief time(h)was 51.20±13.81 and 53.25±16.50(P>0.05),respectively.There was significant difference in the H1N1 quantitative PCR results and positive to negative rate between treatment group and control group(P<0.05).Conclusions GanMao XiaoYan tablets with the main characteristics of Chinese medicine in Yunnan Province is safe and efficient in the treatment of influenza A(H1N1)infection,able to quickly alleviate the influenza-induced fever,sore throat and other symptoms.It can reduce the viral load in respiratory secretions quickly,and speed up the virus turn to negative.

Objective To explore the expression of heme oxygenase-1 (HO-1) mRNA in myocardium of neonatal rats with hypoxic-ischemic encephalopathy (HIE) as well as the relationship with apoptosis in myocardium. Methods Seven-day-old SD rats were randomly divided into HIE group, HIE+Znpp group and control group. Expression of HO-1 mRNA as well as the relationship with apoptosis after HIE in neonatal rats in 3 groups were determined by in situ hybridization and terminal deoxynucleotidy transferase mediated UTP-biotin nicr end labeling. Results 1.In the myocardium, expression of HO-1 mRNA increased sharply at 6 h(P<0.05), and after HIE 12 h reached the peak from 12 h to 24 h, and then decreased gradually after 48 h, which was still higher than that in control group at 72 (P(subscript a)<0.01). In HIE+Znpp group, HO-1 mRNA decreased compared with that in control group, and increased gradually after 48 h(P<0.05). 2. In HIE group, apoptosis of myocardial cells increased gradually after 6 h, and reached highest at 48 h, but from 72 h it decreased gradually. In HIE+Znpp group, apoptosis of myocardial cells was increased gradually after 6 h, at 12 h was highest, after 24 h decreased gradually, but compared with control group and HIE group, it was still higher (P<0.01, 0.05). Conclusions Expressions of HO-1 in neonatal rats myocardial cells may increase after HIE, which suggests that HO-1 mRNA is associated with asphyxia myocardial cells apoptosis.
