“The second class” in medical college is an important carrier of humanities education.In order to give full play to its function,we must effectively rationalize the organization and management of medical humanities education institutions,not only to broaden the content and form of“ the second class”,but also to establish appropriate evaluation incentives.

OBJECTIVE:To study the use and developmental tendency of psychotolytics in hospitals of Guangdong province.METHODS:The psychotolytics used in hospitals of Guangdong province during the period of2000～2004were an-alyzed statistically in respect to consumption sum,DDDs and average daily expense.RESULTS&CONCLUSIONS:Both consumption sum and DDDs of psychotolytics in the past5years increased to a large extent.Benzodiazepine topped the list of anti-anxiety drugs.The consumption of2nd generation antipsychotics increased year by year.On the whole,the consumption of antidepressants increased annually,of which,fluoxetine,flupentixol/melitracen and paroxetine were the most frequently used drugs.However,the consumption of tricyclic antidepressants has a significant reduction.

Objective To determine the effect of Nuclear factor-erythroid 2-related factor 2 ( Nrf2 ) on acute hephrotoxicity induced by CCl4 in male rat.Methods 20 male Wistar rats were randomly divided into control group and CCl4 group, 10 rats in each group, another 10 male Wistar rats were transgenic rats microinjection through the carrier, obtained the Nrf2-tk gene integration and specific transgenic rats, as the CCl4 +Nrf2 integration group.The groups was given 1%polysorbate 80 for 4 days,Then the CCl4 and CCl4 +Nrf2 integration group were intraperitoneally injected with a single dose of CCl47.5 mg· kg-1 and were killed 24 h after CCl4 injection.The serum chemical parameters including asparate aminotransferase ( AST) ,alanine aminotransferase ( ALT) and lactate dehydrogenase ( LDH) were measured.Also malonaldehyde ( MDA) ,glutathione ( GSH) ,oxidized glutathione ( GSSG) levels in the liver as well as glutathione ( GSH)/oxidized glutathione ( GSSG ) ratios were detected. Histopathologic changes in the liver were examined. Results F1generation TK transgenic rats in liver and testis and other tissues and organs were not detected the transcription of Nrf2-tk, indicating that Nrf2-tk expression in tissues is specific good.Nrf2 significantly reduced serum AST, ALT and LDH levels in a dose-dependent manner.The results of MDA levels and GSH/GSSG ratios in liver and kidney showed that Nrf2 reduced CCl4-induced hepatic lipid peroxidation,and ameliorated glutathione depletion.The histopathologic results showed that Nrf2 restrained liver and kidney damage induced by CCl4 .Conclusion Nrf2 can effectively protect male rat from acute hepatotoxicity and nephrotoxicity induced by CCl4 .

Objective To evaluate the safety of temporary cardiac pacemaker during perioperative period of laparoscopic cholecystectomy (LC) in patients with bradyarrhythmia. Methods Temporary cardiac pacemakers were installed preoperatively in 34 elderly patients with bradyarrhythmia for LC. On operation the ultrasonic harmonic scalpel, instead of electrotome, was used to perform dissection and coagulation. Results LC was completed successfully in all the 34 patients without surgery-related complications or perioperative serious cardiovascular diseases. Conclusions Utilization of temporary cardiac pacemaker and ultrasonic harmonic scalpel may considerably enhance the perioperative safety and reduce the incidence of cardiovascular complications in elderly patients with bradyarrhythmia.

Objective Intestinal obstruction is a frequent sequela of recurrent ovarian cancer and difficult to deal with We analyzed a series of such patients to determine if their outcomes have changed after undergoing palliative surgery Method We retrospectively reviewed 67 patients undergoing surgery for intestinal obstruction due to recurrent ovarian carcinoma and 75 patients receiving non surgical treatmen from 1997 to 2002 Results During the study period,67 operations were performed on 67 patients Among them,surgical procedure was completed in 58 cases Successful palliation was achieved in 64 2% of cases in which surgical correction was possible The median survival of the entire cohort was 7 8 months,and 12 6 months for the surgically successfully relieved patients and 3 7 months for those non surgical patients The rate of major surgical morbidities was 22 4 % The perioperative mortality rate was 6 0% Successful palliation was associated with the absence of two prognostic factors:multiple obstructive sites and palpable abdominal and pelvic masses Conclusion Palliative surgery for bowel obstruction in recurrent ovarian cancer can be worthwhile,and properly selected patients are the key to its success

Objective In order to know the effective of local oxygen therapy to promoting renovation of residual surface of bums wound.Methods Divided 60 patients with burns into the experimental group and the control group,there were 30 cases in the each group.Routine nursing cares were used in the control group,while the local oxygen therapy was used in the experimental group.Compare the condition of secretion of wound between the two groups.Results The wound healing time of experimental grou was(5.87±3.29)d,which significant shorten than that of in the control group,the kinds of bacteria in the control group was more than in the experimental group.Conclusions The local oxygen therapy can effective promote the healing of residual surface of bums wound,which can reduce the infection rate of bacteria.

Purpose To investigate the clinical outcome of induced membrane technique for treatment of post-traumatic tibial osteomyelitis.Methods A retrospective analysis was made on 17 cases of post-traumatic tibial osteomyelitis admitted from August 2011 to October 2012.There were 13 males and 4 females aged 19-67 years (mean,40.9 years).Mean length of bone defect was 6.7 cm (range,2.0-18.5 cm).Surgical treatments were performed including phase Ⅰ surgical debridement and antibiotics-loaded bone cement impregnation to induce a membrane and phase Ⅱ bone defect reconstruction by intramembranous bone grafting.Clinical effect of the treatment was evaluated.Results Bone healing was detected at the 27-month follow-up (range,24-32 months).Radiographic healing was obtained 4-6 months after operation.Two cases of recurrent infection were noted after phase Ⅰ surgery and had another debridement.External fixator proximal pin track infection occurred in one case and infection was controlled by hardware removal and dressing change.There was one case of metal rejection,two function disorders,one clubfoot,and one ankle stiffness.Conclusion Induced membrane technique is effective in the treatment of post-traumatic tibial osteomyelitis,especially in lone bone defect reconstruction,but limb functional complications are worth consideration during treatment.

Objective: To evaluate the effect of online lifestyle intervention based on cognitive behavior adjustment on the female patients with infertility and central obesity. Methods: From November 2019 to November 2020, the women with infertility and central obesity in the Reproductive Medicine Center of Zhejiang Provincial People's Hospital were recruited and divided into two groups. The intervention group received online lifestyle intervention based on cognitive behavior adjustment for twelve weeks, and the control group received routine health education. Body weight, waist circumference, fasting blood glucose, fasting insulin, insulin resistance index (HOMA-IR), body fat, the pregnancy rate and the abortion rate were compared between the two groups. Results: There were 78 cases each in the intervention group and the control group, aged (31.15±4.87) years and (31.17±4.81) years, respectively. There were no significant differences between the two groups in age, body weight, body mass index, waist circumference, waist-hip ratio, fasting blood glucose, fasting insulin, HOMA-IR and body fat percentage before intervention (all P>0.05). After twelve-week intervention, the results of mixed effect model showed that the decrease of waist circumference, fasting insulin and body fat percentage in the intervention group were greater than those in the control group (all P<0.05). After six-month follow-up, there was no significant differences in the pregnancy rate (33.33% vs. 23.08%) and the abortion rate (7.69% vs. 16.67%) between the two groups (both P>0.05). Conclusion Online lifestyle intervention based on cognitive behavior adjustment helps to control central obesity and hyperinsulinemia.
