Lumbar disc herniation is a relatively common disease in orthopedics, most patients will experience varying degrees of waist pain after suffering from this disease, and severe cases may even be paralysed. In recent years, with the rapid progress of science and technology, minimally invasive surgery technology is also developing rapidly, and its advantages are also very prominent. Puncture technology, as one of the most important and difficult points, has a high requirement for doctors, so it is particularly important to master this technology thoroughly. In order to apply this technique more in clinical practice, improve its accuracy and success rate, and increase the efficiency of operation, 40 patients with lumbar intervertebral disc herniation were selected and randomly divided into experimental group (20 cases) and control group (20 cases). According to the principle of lumbar intervertebral space puncture, its length and angle were adjusted with high precision. Percutaneous lumbar intervertebral foramen puncture locator was used for treatment in the experimental group and the control group was treated with routine nursing intervertebral foramen puncture. The number of punctures, the time needed for successful puncture, the number of successful projections, puncture complications, and clinical efficacy of the two puncture methods were analyzed. The results showed that in the analysis of clinical puncture indicators, the number of punctures, the time needed for puncture, and fluoroscopy times in the experimental group were significantly different from those in the control group (P < 0.01). The puncture method was determined through the design of the surgical approach to alleviate the symptoms as much as possible after operation. In the visual analogue score, follow-up showed that the visual analogue score of the experimental group was significantly lower than that of the previous one month and the last follow-up, with statistical significance (P < 0.01), and the excellent and good rate was significantly increased by using lumbar intervertebral disc puncture, which was 94.7%. Therefore, through this study, it is found that the new type of lumbar intervertebral perforation positioning designed in this study can significantly improve the accuracy of puncture, the success rate increased significantly, and the experiment achieved the desired results. Although there are some shortcomings in the experiment, it still provides experimental basis for the clinical application of lumbar intervertebral disc puncture in the later stage.

Objective To explore the influence of Rosenthal effect on the psychological status of pregnant women at risk of miscarriage in early pregnancy. Methods From January 2014 to June 2015 151 cases of early pregnancy abortion risk women were set as the control group, and was given conventional psychological intervention.From July 2015 to December 2016 135 cases of early pregnancy abortion risk women were named as the observation group by convenient sampling selection, which was given interventionbased on Rosenthal effect on the basis of routine psychological intervention. The Self-rating Depression Scale (SDS) and the Self-rating Anxiety Scale (SAS) score, the introversion and extroversion scores and the satisfaction degree with intervention were compared between the two groups before and after the intervention. Results There was no significant difference in SDS and SAS scores, inotropic challenge and extroversion challenge between the two groups before treatment (P >0.05). The scores of SDS and SAS, the inotropic challenge and extroversion challenge scores were 41.45 ± 4.26, 40.34 ± 5.82,4.76 ± 1.03,5.55 ± 1.26 in the observation group after intervention,and 47.22 ± 3.93,47.18 ± 7.04,5.39 ± 1.12, 6.43 ± 1.86 respectively in the control group. There were significant difference in scores of SDS and SAS, the inotropic challenge and extroversion challenge (t=2.215-2.573, P <0.05). The satisfaction rates of the observation group and the control group were 93.32%(126/135)and 74.17% (112/151) respectively, the difference was statistically significant (χ2=5.921, P<0.05). Conclusions The intervention based on Rosenthal effect on the basis of conventional psychological intervention for early pregnancy abortion risk women can relieve negative emotions such as anxiety and depression, besides it can also improve satisfaction degree of inpatients with intervention.

Background: Preeclampsia is the most challenging clinical entity affecting both mother and the foetus. It is one of the leading causes for maternal as well as perinatal morbidity/mortality. Preeclampsia appears to be mild in about 75% of the cases and severe in 25% of them. The present study is an attempt to analyse maternal and perinatal outcome in a severe preeclampsia and to find the usefulness of the clinical and investigative work up as predictors of outcome. Materials and Methods: In this observational study 140 women with a severe preeclampsia who were evaluated and managed at a tertiary care hospital were recruited. Clinical, haematological and other biochemical investigative parameters were noted and subsequently correlated with various adverse maternal outcomes. Results: Mean arterial pressure>127 mmHg (p=0.042), uric acid>7 mg/dl (p=0.001), platelet count 1.2 mg/dl (p=0.025) were significantly associated with poor maternal outcome in women with severe preeclampsia. Conclusions: Maternal and perinatal morbidity is still high among women with severe preeclampsia. Timely caesarean delivery seems to improve perinatal outcomes in settings with facilities for new-born care.
