ObjectiveTo investigate the clinical efficacy of primary and connecting point combination acupuncture in treating mild and moderate depression.MethodPatients meeting the inclusion criteria were randomly allocated to observation and control groups. Both groups of enrolled patients took fluoxetine hydrochloride (Prozac). The observation group received meridian-unblocking acupuncture at yuan-primary points and luo-connecting points and the control group, acupuncture at routinely selected points in the eleventh-five textbook. Treatment was given for four consecutive weeks. The Hamilton Depression Scale (HAMD) 24-item score was recorded in the patients before and after one month of treatment. The therapeutic effects were evaluated according to the score reduction rate in the two groups.ResultThere wasa statistically significant post-treatment difference in the HAMD 24-item score between the two groups (P<0.05). The total efficacy rate was83.3% in the treatment group and70.0% in the control group. There was a statistically significant post-treatment difference in therapeutic effect between the two groups (P<0.05). ConclusionMeridian-unblocking acupuncture at yuan-primary points and luo-connecting points is more effective than conventional acupuncture in proving the symptoms in patients with mild or moderate depression.

AIM:To investigate the differences of clinical signs and pathological structure of unilateral nasal pterygium and unilateral double pterygium.METHODS:Retrospective study.Totally 11 unilateral nasal pterygium and 11 unilateral double pterygium were collected to observe the size of the tissue area, the classification of blood vessels, the transparency and the break-up time of tear film.The 11 surgically excised double pterygia (11 eyes) and 6 samples of normal conjunctiva were collected for the study.With 40g/L paraformaldehyde fixation, paraffin sections were stained with Haematoxylin-Eosin, to observe the differences with nasal and temporal pathology under light microscope.RESULTS:In unilateral double pterygium, the tear break-up time was significantly shorter than that of unilateral nasal pterygium (t=3.410, P=0.003).In unilateral nasal pterygium, there was a significant negative correlation between tear film break-up time and tissue size(r=-0.927, P<0.01) and transparency(r=-0.764,P<0.01).In unilateral double pterygium, the tear break-up time was significantly negatively correlated with the growth time (r=-0.661, P<0.05), tissue size (r=-0.775, P<0.01) and transparency (r=-0.671,P<0.05).In unilateral double pterygium, compared with the temporal side, the quantity of the layers of corneal epithelial cells (t=-7.351, P<0.05), vessels (t=-7.400, P<0.05) and inflammatory cells (t=-7.481, P<0.05) increased.CONCLUSION:Compared with unilateral nasal pterygium, the tear film break-up time of unilateral double pterygium was poor.In unilateral double pterygium, with high activity, the degree of proliferation of squamous epithelium, hyperplasia and inflammatory reaction are significantly higher than those of the temporal side.

Objective With the sole object of glycyrrhizic acid products,the methods were investigated for Glycyrrhiza uralensis genomic DNA transformation into Hansenula anomala by nitrogen and argon ion implantation.Methods The genomic DNA from G.uralensis was randomly transferred into H.anomala by nitrogen and argon ion bombardment.The recombined yeasts were cultured by the slant and liquid cultivation,in which the contents of glycyrrhizic acid and glycyrrhetic acid were determined by acetic anhydried-H2SO4 qualitative test and RP-HPLC determination.Results Five recombined yeast strains that produced glycyrrhizic acid and glycyrrhetic acid were obtained.After cultured in liquid medium for 96 h,the highest content of glycyrrhizic acid in the cultivation liquid was 114.49 mg/L and that of 18?-glycyrrhetic acid and 18?-glycyrrhetic acid were respectively 0.56 and 0.81 mg/L by RP-HPLC.A kind of unknown red component was found in the cultivation liquid of one recombined strain by TLC.Conclusion The recombined yeast strains of producing glycyrrhizic acid could be obtained G.uralensis genomic DNA transformation into yeast mediated by the ion implantation.

Objective To investigate the value of micro-course in colostomy patients in self-care. Methods A total of 120 patients with colostomy patients were divided into the intervention group and the control group with 60 cases each according to the first time in the hospital bed and odd number. The intervention group was given micro-course in colostomy patients discharge health education. The control group was taken the traditional health education missionary single conduct health education of discharged. The self-efficacy (divided stoma care effectiveness and social effectiveness of two dimensions and six separate entries, score 28-140 points. Using five no confidencethere a little confidence some of confidencequite confident or very confident scoring 1-5 points) and stoma care skills (including two parts, a total of 18 entries, each entry method using Likert scale of 51-5 points representing very unskilledsomewhat skilledordinary skillskilled and very skilled, score 18-90 points, higher scores indicate better skills) of patients after 3 months of discharge between the two groups were compared and evaluated. Results After 3 months of discharge, the self- efficacy scores of the intervention group were evaluated with respect to stoma care, social performance, diet choice, confidence in sex life, confidence in sexual life, confidence in physical activity, confidence in vitality and confidence in self-care (53.17±3.54), (38.62±5.25), (3.45 ± 1.06), (2.43 ± 1.06), (2.22 ± 0.86), (2.88 ± 0.94), (3.52 ± 0.89), (3.88 ± 0.64) points, respectively, compared with the control group (50.45 ± 4.79), (35.33 ± 3.42), (3.03±1.15), (1.77±0.81), (1.78±0.72), (2.47±0.96), (3.02±0.70), (3.40±0.81) points, there were significant differences (t=-4.366--2.076, all P<0.05) . According to the comparison of stoma nursing skills, the score of stoma care and the related knowledge of stoma care were (36.33±4.21), (37.13±3.85) points in the intervention group, and (34.22±3.87), (31.32±4.95) points in the control group, and there were statistically significant difference (t=-3.140,-7.741, P < 0.05). Conclusions Colostomy patients discharged from hospital health education classes in the use of micro-course, can effectively improve patients' self-efficacy and ostomy care capacity, enhance the quality of life.

Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.

An experimental study on flowrate and stability of a type of control valve of 600MW supercritical steam-turbine was presented by measuring instruments of static, dynamic pressure and vibration in self-designed test rig. The investigation shows that flow coefficient is 30% up more than that of the control valve of GX-1 type used widely in domestic power plants now, as small-medium lifts. If the relative lift (h/D) is less than 20%, the valve can always work steadily in all the pressure ratios. When the h/D is between 20% to 24%, big vibration of valve stem occurs if the pressure ratio is between 0.7 to 0.8. When h/D is more than 25%, relatively great vibration happens in a wide range of pressure ratios of 0.4 to 0.85.

The conception of evidence-based medicine (EMB) has a strong influence on the medical world since it built up.This concept has been widely used in all sorts of clinic and basic medical research,however,it is little reported to be practised in our fundamental medical education.As for it,this article will briefly analyze the importance of introducing the idea into fundamental medical education,and for one thing,suggest some more reform measures for medical teaching staff.

Objective To investigate the association between serum non-organ-specific autoantibodies and polycystic ovary syn-drome(PCOS).Methods A total of 69 patients with PCOS in child-bearing period treated in our hospital were selected as the study group and contemporaneous 69 healthy child-bearing year women were selected as the control group.Serum level of antinuclear anti-bodies (ANA)was measured by ELISA,serum level of anti-dsDNA was measured by colloidal gold spot infiltration assay and the extractable nuclear antigen (ENA)auto-antibodies profiles were measured by Western blot.Results Serum levels of ANA and an-ti-dsDNA antibodies in the study group were significantly elevated compared with the control group with statistical difference.Con-clusion Serum autoantibody positive exists in the patients with PCOS.

Objective To introduce the techniques and specification of complete-block radical gastrectomy, and to compare with traditional radical gastrectomy in the operative time, surgical costs and postoperative complications. Methods Thirty gastric cancer patients meet the criteria were randomly divided into 2 groups. Group A: complete-block radical gastrectomy;group B: radical gastrectomy. Analysis and comparison were made on tumor site, time consuming of block, the proportion of gastrointestinal reconstruction, operative time, cost of block, pathological TNM stage, length of stay, postoperative complications and postoperative chemotherapy. Results Group A has longer operative time than group B (P<0.05). However, there was no significant statistical difference in the other indicators between these 2 groups. Conclusions Complete-block technology can separate cancer more completely during operation with the advantage of simplicity, low-cost, little effect on the subsequent operation. The incidence of postoperative complications and length of stay with the traditional surgery there was no significant difference.
