Objective To know the usage of Chinese patent medicine of western medicine doctors in general hospitals. Methods By means of informal discussion with experts, present situation was known; By means of screening questions in questionnaire, nationwide investigation was conducted by this questionnaire about Chinese patent medicine and the results were examined by statistical analysis. Results That the abuse of Chinese patent medicine by western medical doctors was quite common. The overall quality of their prescriptions was not good. Most of the doctors have never received specialized continuing education of traditional Chinese medicine, only having preliminary knowledge or nothing on syndrome differentiation and treatment of traditional Chinese medicine. Conclusion The management department should take following measures: further enhance continuing education of TCM;formulate related policies;improve present situation.

Objective To investigate the anti-inflammatory effect of peroxisome proliferator-activated receptor-γ(PPAR-γ)in non-obese diabetic mice(NOD mice)with Sj(o)gren's syndrome(SS)．Methods Twenty 8-weeks-old female NOD mice were randomly divided into 2 groups．Rosiglitazone and normal saline were administered for the rosiglitazone group and control group respectively．At age of 12 weeks and 15 weeks，one mouse in the rosiglitazone group and the control group were killed respectively,and the others were sacrificed at the age of 17 weeks．Blood were obtained by cardiac puncture，and minor salivary glands (MSG) were resected．The histopathological changes waere examined by H&E staining．The level of IL-1β，IL-4，IL-6 and TNF-α in serum were measured by ELISA．Real-time PCR waft used to evaluate the mRNA expression level of IL-1β，IL-4，IL-6 and TNF-α in MSG．Student's t-test was used to assess the differences．Results Compared with the control group，the mice in the rosiglitazone group showed that：①histopatho-logical change was significantly ameliorated．②At the age of 17 weeks，IL-6[(26±7)vs(37±11)，t=-2．298] and TNF-α[(57±22)vs(79±21)，t=-2．188] were expressed significantly lower and IL-4[(26±13)vs(12±4)，t=2．438 ] was expressed significantly higher in serum(P<0．05)．③The expression of TNF-αwas significantly decreased and the expression of IL-4 was significantly increased in MSG (P<0．05)．Conclusion PPAR-γ can ameliorate SS on NOD mice effectively．The mechanism may be related to reduction of Th1 cytokines，and the Th1/Th2 balance is changed into Th2 predominant．

Objective To investigate the diagnostic value of electrophysiological examination for tarsal tunnel syndrome (TTS).Methods Motor nerve conduction velocity (MCV),sensory nerve conduction velocity (SCV),F wave and electromyographic measurements were carried out with 26 clinically suspected TTS patients.Results Of the 26,22 patients were unilaterally affected and 4 were bilaterally affected,so 30 tarsal tunnels in total were affected.All received electrophysiological examination.Of the 30 affected tarsal tunnels,abnormal MCV was detected in 28 of the posterior tibial nerves (93.3％),while abnormal SCV was detected in 27 medial plantar nerves (90％) and 24 lateral plantar nerves (80％).Needle electromyography of 156 targeted foot muscles detected abnormal spontaneous potentials in 90 of them (57.7％),giant potential in 12 muscles (7.7％) and decreased recruitment in 76 (48.7％).Conclusions The distal posterior tibial nerve is impaired in TTS,presenting axonal damage in an electrophysiological examination.Such examinations should have an important role in the diagnosis and differential diagnosis of TTS.

Objective To explore the effect of melatonin(MT) on connective tissue growth factor(CTGF) and the airway remodeling in asthmatic mice.Methods The mice were randomly divided into 4 groups as control group,asthmatic group,MT treated group and dexamethasone treated group.The mice were sensitized and repeatedly challenged with ovalbumin(OVA) for 2 and 4 weeks.MT treated group were intraperitoneal injected with MT,and dexamethasone treated group were intraperitoneal injected with DXM.The eosinophils around the airway were examined with microscopy after histochemical staining.Masson staining was used to stain collagen fibers and PAS staining was used to stain airway mucus.The following parameters including the perimeter of bronchial basement membrane (Pbm),total bronchial wall area(WAt),inner wall area(WAi),smooth muscle area(WAm),collagen area(Wcol) and mucus area were measured by Leica image analysis software.The protein expression of CTGF was assessed with immunohistochemistry.Results WAt/Pbm,WAi/Pbm,WAm/Pbm,Wcol/Pbm,the mucus area and the expression of CTGF were significantly higher in asthmatic group than those in control group.MT treated group and dexam ethasone treated group significantly alleviated the above-mentioned indicators increased.Conclusion MT inhibits the expression of CTGF and airway remodeling,which has a comparative potency of dexamethasone.

Objective To discuss the technical specifications of current high-frequency electrotome detection,to avoid the hidden danger of high-frequency electrotome power detectors,and to measure the leakage current of different kinds of highfrequency electrotome accurately.Methods The power and leakage current of the high frequency electrotome were measured by FLUCK QA-ES Ⅱ high frequency electrotome analyzer.The safety of the two methods was compared before and after the improvement of the power measurement.Four parameters of leakage current were repeatedly measured with the ways of high frequency earthing and high frequency isolation respectively.The maximum measurement of leakage current was recorded.Results The improved connection method was safe in the power measurement.For the high-frequency electrotome in the model of high frequency earthing,the values of leakage current were restrained within the range of error with two ways of monopolar loading operation electrode and neutral electrode.For the high-frequency electrotome in the model of high frequency isolation,the values of leakage current were limited within the range of error withtwo ways of monopolar empty operation electrode and neutral electrode.Conclusion The improved high-frequency electrotome power detection method is safe for detectors.The data obtained from the leakage current detection method using the national standard correction method reflect the actual state of the high-frequency electrotome,when the electrotome with earth as the reference is used to detect the leakage current with loading or the insulated electrotome is applied to measuring the leakage current with no loading.

Aim To investigate the role of autophagy and its mechanism in Raji cell death induced by arse-nic trioxide. Methods Transmission electron micros-copy ( SEM) and MDC fluorescence staining were used to observe autophagy. MTT colorimetry was employed to assay the cellular proliferating activity. Cell apopto-sis and cell cycle analysis were performed using FITC-Annexin-V/PI double staining and flow cytometry ( FCM) . The expressions of LC3 and the conversion of LC3-I to LC3-II were measured by western bloting. The expression of bcl-2 mRNA and p53 mRNA were detected by reverse transcription-polymerase chain re-action ( RT-PCR ) . Results Arsenic trioxide could obviously inhibit the proliferation of Raji cells, arrest the cells at G2/M phase and induce apoptosis. Mean-while, arsenic trioxide markedly inhibited the expres-sion of bcl-2 mRNA and enhanced the expression of p53 mRNA in Raji cells. Arsenic trioxide also induced autophagy synchronously which paralleled with the in-duction of apoptosis in Raji cells, and 3-MA, an auto-phagy inhibitor, was able to reverse the arsenic triox-ide-activated autophagic activity, up-regulate bcl-2, down-regulated p53 expression and suppress the lethal effect of arsenic trioxide on Raji cells to reduce their sensitivity to arsenic trioxide. In contrast, the Rapamy-cin, an autophagy inducer, possessed the completely opposite effects on Raji cells compared with 3-MA. Conclusions The apoptosis and autophagic cell death are coexistent in arsenic trioxide-triggered death of Raji lymphoma cells, and Bcl-2 and p53 may play a key regulating role in this process.

BACKGROUND: Zein has excel ent solubility, heat resistance and biodegradability, but its biocompatibility and effect on periodontal defects repair are under discussion. OBJECTIVE: To analyze biocompatibility of zein and its effect on periodontal defect repair. METHODS: Zein scaffold was prepared by solvent casting/particulate leaching. In vitro test: Human periodontal ligament cel s were co-cultured with zein scaffold for 18 days, and cel growth was observed by scanning electron microscope. In vivo test: Eight Beagle dogs were enrol ed to establish periodontal defect models, which were randomly assigned to receive zein scaffold implantation as experimental group, or interrupted suture as control group. Afterwards, the defect region was observed by scanning electron microscope at 3 months. RESULTS AND CONCLUSION: In vitro results: Human periodontal ligament cel s adhered wel and tightly on the scaffold with a fusiform, and could grow around pores. In vivo results: In the experimental group the scaffold dissolved completely, bone trabecular arranged regularly, and mature tissues appeared, to be integrated with the surrounding tissues; in the control group, the defect region almost healed, but there were irregular fibers and obvious lacunae. Moreover, compared with the control group, the height of new alveolar bone and bone defect, as wel as the length of junctional epithelium were significantly decreased, and new cementum was significantly increased in the experimental group (P < 0.05). To conclude, zein scaffold has good biocompatibility and can promote periodontal defect repair.

Objective To understand the perceptions of normal and ideal body size in registered nurses and nursing students,and to analyze the impacts of individual weight levels and misperception of body weight on their such cognitions.Methods A cross-sectional survey of 407 nursing students from two hospitals and 466 registered nurses from one hospital was conducted with the questionnaire survey.Sociodemographic information,actual weight,perceived weight levels and scores for figure rating scale were included.Results FRS scores for normal and ideal body size to male were significantly higher than to female either in registered nurses or in nursing students; FRS scores for ideal body size to both sexes were significantly lower than those for normal body size among registered nurses and nursing students.There were no statistically significant associations between FRS scores for normal and ideal body size and individuals' weight levels and misperceptions of body weight among registered nurses and nursing students.Conclusions There existed differences in rating female and male body size among registered nurses and nursing students,with “bigger” normal and ideal body sizes to male,Nurses preferred to “thinner” ideal body size in comparison to normal body size.
