Objective To discuss the correlation between procrastination and the mentalities of anxiety and depression among medical postgraduates,so as to carry out mental health work effectively.Methods 423 medical postgraduates in Central South University were assessed randomly, using General Procrastination Scale (GPS),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale (SDS).Results Procrastination score and incidence in medical postgraduates was 54.92±8.40 and 60.99%respectively,the differences of procrastination scores(53.3l±8.21,55.90±8.30,55.75±8.49,P=0.013)and incidences(52.60%,66.09%,65.58%.P =0.028)among three grades were statistically significant.Both total coarse score of anxiety and that of depressionwere higher than that of the whole country(31.24±7.40,29.78±10.07,P=0.000;34.8±8.11,33.46±8.55,P=0.000),the differences were statistically significant.Procrastination had a positive correlation with anxiety and depression significantly(r=0.304,P=0.000;r=0.369,P=0.000),the higher the grade was,the weaker the intensity of correlation was.Hish-delay group,low-delay group and normal-behavior group had different deglees of anxiety(46.63±10.55,44.01±10.12,38.32±7.57,P=0.000)and depression(51.45±10.12,47.81±10.78,40.69±8.23,P=0.000),which was statistically significant.Conclusion Anxiety and depression among medical postgraduates were outstanding and had a close relationship with procrastination behavior,which should be taken seriously and handled by strengthening mental health education.

Objective:To reveal the action mechanism and efficacy of electroacupuncture (EA) plus external application of Wei Ling Xian (Radix Clematidis) extract in treating knee osteoarthritis (KOA), for providing theoretical evidence and novel plan for the treatment of KOA.Methods:Totally 284 inpatients were divided into an EA group and an observation group by the random number table, 142 cases in each group. The EA group was intervened by EA, ultrashort waves, and oral administration of Glucosamine Hydrochloride capsules; while the observation group was by external application of Wei Ling Xian (Radix Clematidis) extract at topical area in addition to the treatment given to the EA group. The intervention lasted 14 d in both groups. X-ray examination of knee joint was ordered before and after treatment, as well as the detection of positive expression of matrix metalloproteinase-1 (MMP-1) in cartilage of knee joint, hyaluronic acid (HA) and interleukin-1β (IL-1β) in the inflammatory effusion; the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and visual analogue scale (VAS) were adopted to evaluate the clinical efficacy.Results:In the observation group, the X-ray examination result of knee joint was significantly improved, the positive expressions of MMP-1 and IL-1β content were significantly decreased, the level of HA was increased, WOMAC and VAS scores dropped, and the total effective rate was 91.5%, which were significantly different from those in the EA group (P<0.05).Conclusion:EA plus external application of Wei Ling Xian (Radix Clematidis) extract can produce a more significant efficacy in treating KOA compared to ordinary EA treatment.

Objective To observe the clinical efficacy of thermal electroacupuncture therapy in treating lumbodorsal myofascitis. Method Sixty-two patients with lumbodorsal myofascitis were randomized into a treatment group of 30 cases and a control group of 32 cases. The treatment group was intervened by thermal electroacupuncture therapy, while the control group was by orally taking Meloxicam tablets. The Visual Analogue Scale (VAS) was observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 100.0% in the treatment group versus 78.1% in the control group, and the difference was statistically significant (P<0.05). The VAS scores were significantly changed after treatment in both groups (P<0.05). After treatment, the VAS score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion Thermal electroacupuncture therapy is an effective approach in treating lumbodorsal myofascitis.

Objective:To study the signal enhancement of lung adenocarcinoma nude mice after injection of immunomagnetic bead solution (magnetic beads conjugated with monoclonal antibody NJ001) in micro-CT scan. Methods:The models of lung adenocarcino-ma nude mice were established by injecting SPC-A1-luc cells through the tail vein and were validated by bioluminescence imaging (BLI). The nude mice were divided into three groups: physiological saline group, bare magnetic bead group, and immunomagnetic bead group. Three groups of nude mice were injected with physiological saline, 750 nm bare magnetic bead solution, and immuno-magnetic bead solution via the tail vein every week, and micro-CT scan was taken before and 4 h after injection. Immunohistochemis-try (IHC) was used to detect the expression of antigen SP70 in tumor tissues. Results:The tumor was detected in the immunomagnetic bead group at the fourth week, whereas in the physiological saline and bare magnetic bead groups, the tumor was undetectable until the sixth week. The tumor intensities detected at the sixth week by micro-CT scan in the physiological saline, bare magnetic bead, and immunomagnetic bead groups were 59.05 ± 0.66, 60.69 ± 0.55, and 58.25 ± 0.32 before injection and 60.30 ± 1.83, 61.05 ± 0.68, and 67.41±3.82 after injection, respectively. Compared with the tumor intensities before injection, they significantly increased after injec-tion in the immunomagnetic bead group;the difference was statistically significant (P=0.0079). By contrast, no statistical significance was observed in the tumor intensities before and after injection in the physiological saline and bare magnetic bead groups (P=0.1867 and P=0.3839, respectively). Conclusion:The immunomagnetic beads had enhanced effect on micro-CT scan of lung adenocarcinoma nude mouse models.

Objective: To investigate the intervention effect of electroacupuncture on post-withdrawal anxiety and depression of those with heroin dependence. Method: One hundred and twenty heroin dependence cases were randomly allocated into 4 groups, including acupuncture group 1 using Jiaji (Ex-B 2) points and Shenshu (BL 23), acupuncture group 2 using points in the four limbs, simulation and control groups. Then the SAS and SDS changes were observed before the treatment and 4th, 8th and 10th week after. Result: At the 4th, 8th and 10th week, the SAS and SDS scores in acupuncture group 1 and 2 showed significant differences with the control group (P<0.01, P<0.05). There were significant differences between SAS changes in acupuncture group 1 and 2 but there was no significant difference in SDS changes. Conclusion:Electroacupuncture can improve the post-withdrawal anxiety and depression in heroin addicts.Jiaji (Ex-B 2) points showed significantly better effects in improving anxiety than points in four limbs but no significant difference in improving depression.

Objective:To analyze the risk factors of pelvic infection after gynecological malignant tumor surgery and construct a predictive model.Methods:The convenient sampling method was used to collect the clinical data of 278 patients who underwent gynecological malignant tumor surgery in Shanxi Provincial People's Hospital from June 2018 to June 2020. According to the occurrence of postoperative pelvic infection, the patients were divided into the infection group ( n=29) and the non-infection group ( n=249) . Univariate and binomial Logistic regression analysis was used to investigate the risk factors of pelvic infection after gynecological malignant tumor surgery, and ROC curve was used to analyze the predictive value of the prediction model. Results:The incidence of pelvic infection in 278 patients with gynecological malignancies after surgery was 10.43% (29/278) . Binary logistic regression analysis showed that whether there were diabetes, chronic pelvic pain, history of preoperative pelvic infection and operation method, operation duration, and hospital stay were the influencing factors of pelvic infection after gynecological malignant tumor surgery ( P<0.05) . ROC curve analysis showed that diabetes mellitus, chronic pelvic pain, history of preoperative pelvic infection, surgical method, surgical duration and length of hospital stay all had certain predictive value for pelvic infection after gynecological malignant tumor surgery, while the predictive value of combined application was higher than that of each index alone. The area under the ROC curve was 0.821 (95% CI: 0.729-0.915) , and the accuracy was 0.817. Conclusions:The presence of diabetes mellitus, chronic pelvic pain, preoperative history of pelvic infection, surgical method, duration of surgery and length of hospital stay are the influential factors for pelvic infection after gynecological malignant tumor surgery. The combined prediction model established based on the above factors has good prediction ability.

OBJECTIVE: To investigate the effect of ziprasidone and olanzapine on glucose and lipid metabolism in first-episode schizophrenia. METHODS: A total of 260 schizophrenics were assigned randomly to receive ziprasidone or olanzapine for 6 weeks. The weight was measured at baseline, week 2, 4 and 6. Fasting blood glucose (FBS), fasting insulin, high-density lipoprotein (HDL), total-cholesterol (TC) and triglycerides (TG) were measured at baseline and the end of 6-week treatment. Low-density lipoprotein (LDL) was measured in some patients at baseline and the end of 6-week treatment. Body mass index (BMI) and insulin resistance index (IRI) were counted. RESULTS: A total of 245 patients completed the trial, including 121 ziprasidone patients and 124 olanzapine patients. The average dose was 137.5 mg/d for ziprasidone and 19.5 mg/d for olanzapine. Patients treated with olanzapine had higher weight gain than those treated with ziprasidone [(4.55±3.37) kg vs (-0.83±2.05) kg, P<0.001]. After the treatment, FBS, fasting insulin, HDL, TC, TG, LDL and IRI levels were significantly increased in the olanzapine group (all P values<0.001 ). However, in the ziprasidone group, FBS decreased significantly and HDL and TG levels increased significantly after the 6-week treatment (all P values<0.05). The mean changes of FBS, fasting insulin, TC, TG, LDL and IRI were significantly different in the two groups (all P values<0.001). CONCLUSION Ziprasidone has less glucose and lipid metabolic effect for first-episode schizophrenia patients in short-term treatment. However, olanzapine induces weight gain and dysfunction of glucose and lipid metabolism significantly, which is associated with increased risk of complications. When the doctors choose antipsychotics in the clinic, they should consider the side effects of the medication.

Objective To survey the situation of spinal cord injuries (SCI) in Beijing.Methods China Rehabilitation Research Center and Information Center of Beijing Health Bureau sponsored the surveillance of 86 hospitals in Beijing which had hospitalized SCI patients in 2002. The faculty of surveillance was composed of trained professionals. The number of registered SCI patients in 2002 was 1077, and 264 patients in 11 hospitals were chosen to be investigated in detail according to stratified sampling result.Results There were 1077 registered patients with a neurological deficit and the annual SCI incidence was 60 per million. The ratio of male to female was 3:1 and the ratio of cervical, thoracic, lumbar injuries and others is 4.9%, 28%, 66.7%, 0.4% respectively. The mean age at the time of injury was 41 years. The causes most frequently seen were falls from a height and traffic accidents. The mean time of hospitalization was 18.9 days and the mean expenditure of hospitalization was 27819.3 RMB. Four patients were transferred to rehabilitation hospitals, and others went homes directly after discharge.Conclusion There are many reasons for the high annual SCI incidence in Beijing and the first SCI cause was falling from a height, which should be pay special attention when the prevention measures are taken into account. The rate of SCI patients who received systemic medical rehabilitation was low.

INTRODUCTION: Pericardiocentesis is a potentially life-saving procedure. We compared two low-cost models-an agar-based model and a novel model, Centesys-in terms of ultrasound image quality and realism, effectiveness of the model, and learners' confidence and satisfaction after training. METHODS: In this pilot randomised 2x2 crossover trial stratified by physician seniority, participants were assigned to undergo pericardiocentesis training either with the agar-based or Centesys model first, followed by the other model. Participants were asked to rate their confidence in performing ultrasound-guided pericardiocentesis, clarity and realism of cardiac structures on ultrasound imaging, and satisfaction on a 7-point Likert scale before and after training with each model. RESULTS: Twenty participants with median postgraduate year of 4 (interquartile range [IQR] 3.75-6) years were recruited. Pre-training, participants rated themselves a median score of 2.5 (IQR 2-4) for level of confidence in performing pericardiocentesis, which improved to 5 (IQR 4-6) post-training with Centesys ( CONCLUSION Centesys achieved greater learner satisfaction as compared to the agar-based model, and was an effective tool for teaching ultrasound-guided pericardiocentesis and drain insertion.
