Objective: To observe the effect of puncturing Juliao (GB 29) in treating carpal joint sprain. Methods: 99 cases were randomly divided into 3 groups, treatment, control 1 and control 2 groups, 33 cases for each group. Cases in treatment group were treated by acupuncture on Juliao (GB 29); patients in control 1 group were treated by acupuncture at Sanyinjiao (SP 6), and patients in control 2 group were treated by local application. The clinical effect was compared among three groups after the treatment. Results: The effective rate in the treatment group is 96.9%, which is over and above 84.8% in control 1 group and 75.8% in control 2 group (both P＜0.05). Conclusion: Acupuncture at Juliao (GB 29) has a precise curative effect in treating sprain of carpal joint. It is more effective than acupuncture at Sanyinjiao (SP 6) and local application.

Objective:To investigate the correlation between human herpesvirus-6(HHV-6) infection and pathogenesis of oral squamous cell carcinoma.Methods:Samples of saliva, peripheral blood mononuclear cells (PBMCs),tumor tissue and tumor adjacent tissue were collected from 82 patients with oral squamous cell carcinoma, 25 patients with oral precancer lesion and 40 healthy young adults(controls). Nested PCR assay was used to examine HHV-6 infection.Results:1)In control, precancer lesion and carcinoma groups, HHV-6 positive rates(%) were 45.0,56.0, 72.0 in saliva, 22.5,48.0,57.3 in PBMCs, and general rates(%) were 47.5,56.0 and 80.5 respectively(control vs carcinoma,P0.05).Conclusions:Saliva gland is the position of HHV-6 latency/proliferation and saliva is the predominant route of HHV-6 transmission; HHV-6 infection correlates to the pathogenesis of oral squamous cell carcinoma.

Objective To investigate the effect of cholecystokinin (CCK) on colon motility and its mechanism in development of irritable bowel syndrome via recording ionic channels currents and contraction of guinea-pig proximal colon. Methods The guinea-pigs (body weight ranged from 200 g to 250 g) were deprived of food, but not water, for 12 hours before experiment. The animal was sacrificed and 6 cm of proximal colon was obtained. The contractile activity of isolated proximal colon in 1 × 10-7 ,5 × 10-7 or 1 × 10-6 mol/L of CCK-8 solution was recorded. The impact of 1 × 10-7 , 5 × 10-7 and 1 × 10-6 mol/L of CCK-8 and 1 × 10-6 mol/L CCK-8 nifidipin on current of calcium activated potassium channel (IBKac) was detected with an EPC-10 amplifier and an image analysis software.Results In comparison with blank [(0. 68 ±0. 12) g], the amplitude of colon contraction in 1 × 10-7 ,5×10-7 and 1×10-6 mol/L of CCK-8 was increased by (15. 0±1.5)%,(28. 0±1.4)%, and (36.0±1.6) %, respectively ( n = 7, P = 0. 023,0. 005 and 0. 01 ), but there was no significant change of frequency. When exogenous stimulation at +60 mV, the current of IBKac was enhanced to (117. 45 ± 3.60)%, (125.42± 5. 30)% or (136. 98±6. 80)% in 10-7 ,5 × 10-7 or 10-6 mol/L of CCK-8,respectively, compared with controls (n= 7, P＜0.01 ). However, after adding nifidipin, the current of IBKca was reduced to (102.23±5.60)% in 10-6mol/L of CCK-8 at +60 mV when compared with controls (n=7, P= 1. 491 ). Conclusion CCK enhances proximal colonic motility by increasing Ca2+ influx and IBKac current, which is characterized by enhancement of amplitude of contraction.

CM gynecology is one of the main courses of traditional Chinese medicine. The cultivation of the doctor-patient communication skills is a very important among the eduction of graduate students. The paper was encouraged to summarize the condition and problems of doctor-patient communication, in order to standardize CM gynecology training and improve the quality of teaching practice.

The National Excellent Course of Gynecology of Chinese Medicine is a main clinical subject of TCM,which puts emphasis on clinical application.The non-medical doctoral students are lack of the knowledge of traditional Chinese medicine and clinical experience,and the existing classroom teaching has the problem of the basic theory of traditional Chinese medicine being out of line with the clinical application,which has become the hindering factors of TCM gynecology teaching.By designing and perfecting the process of preparation before class-classroom teaching-discussion teaching-clinical probation-after class feedback,the related teaching teachers better improve the non medical doctoral students' ability to put the traditional Chinese medicine gynecology basic knowledge into clinical practice,which is well received by the students.

Objective_To investigate whether hUCMSCs undergo malignant transformation when exposed to MCF-7B breast cancer microenvironment and whether the abnormal activation and over expression of STAT3 play an impor-tant role in this transformation.Methods_The experiment was divided into three groups:blank group ( hUCMSCs were separately cultured),experimental group(hUCMSCs were indirectly co-cultured with MCF-7B breast cancer cells),positive control group(MCF-7B breast cancer cells were separately cultured).Morphology of cells was detec-ted by invertedmicroscope.Cell cycle was detected by flow cytometry.The mRNA expression of STAT3, c-Myc and Bcl-xL was tested by real-time PCR.The protein expression and location of p-STAT3,c-Myc and Bcl-xL were detected by immunofluorescence.The protein expressions of p-STAT3,STAT3,c-Myc and Bcl-xL were also meas-ured by Western blot.Results_The experimental group cells showed typical morphology of the tumor cells.The cells proportion of experiment group in G1 phase was significantly lower than that of the blank group(P<0.05),but which in S and G2 phase were significantly higher than those of the blank group(P<0.05).The mRNA expression levels of STAT3 ,c-Myc and Bcl-xL in experimental group was significantly higher than those in blank group ( P<0.05).p-STAT3,STAT3,c-Myc and Bcl-xL protein were significantly higher than those of the blank group(P<0.05),and they were mainly located in the nuclei.The protein expression of STATS also showed significant changes in experimental group.Conclusions_hUCMSCs trends to malignant transformations when exposed to MCF-7B breast cancer microenvironment.The abnormal activation and over expression of STAT3 are of important factors leading to the malignant transformation of hUCMSCs.

Objective: To explore risk factors for complicated cardiovascular and cerebrovascular diseases in patients with refractory hypertension (RH).Methods: Clinical data of 536 RH patients, who were treated in our hospital from Jun 2010 to Jul 2015, were retrospectively analyzed.According to presence of cardiovascular and cerebrovascular diseases or not, patients were divided into complication group (n=217) and pure RH group (n=319).Results: Compared with pure RH group, there were significant rise in percentages of drinking and smoking, hypertension course, mean arterial pressure (MAP), mean systolic blood pressure, pulse pressure, serum uric acid (SUA), creatinine (Cr), total cholesterol and low density lipoprotein cholesterol (LDL-C), and significant reductions in high density lipoprotein cholesterol (HDL-C) mean diastolic blood pressure and mean heart rate in complication group, P<0.01 all.Multi-factor unconditional Logistic regression analysis indicated that hypertension course, SUA,MAP, Cr and LDL-C levels were independent risk factors for complicated cardiovascular and cerebrovascular diseases in RH patients (OR=1.014~3.217, P<0.05 or <0.01).Conclusion: Hypertension course,MAP,Cr,SUA and LDL-C are independent risk factors for refractory hypertension.Enhancing their monitor, prevention and treatment are important to reduce incidence rates of cardiovascular and cerebrovascular complications in patients with refractory hypertension.

Objective:To study dynamic changes of fragile histidine triad(FHIT) gene expression in ionizing radiation injury and radiation carcinogenesis. Methods: BEAS-2B cells were divided into 0.5,1,2,4,8,16 Gy irradiation groups and control group. In 24 h, 72 h and 10 d after irradiation, the expression of FHIT gene was studied with single-cell RT-PCR and DNA sequencing separately. Results: Different types of FHIT gene mutations occured in different phases after irradiation with different doses (All mutations were exon deletion mutations by DNA sequencing), while abnormal FHIT gene was not detected in control group. The percentage of mutation in 0.5,1,2,4,8,16 Gy dose groups was 52.6%,66.7%,57.9%,76.5%,64.7% and 81.3% respectively 24 h after irradiation;17.6%,22.2%,50.0%,47.4%,47.1% and 68.4% respectively 72 h after irradiation;and 21.1%,25.0%,60.0%,57.9%,61.1% and 68.4% respectively 10 d after irradiation. Conclusion: These results suggest that ionizing radiation can cause deletion of FHIT gene.

ObjectiveTo investigate the application of rapid immunohistochemical staining technique in intraoperative frozen section diagnosis of thyroid neoplasm.Methods MaxVision one-step rapid immunohistochemical staining technique was used to detect the expression of CK19,HBME-1,and Gal-3 in frozen section of papillary thyroid carcinoma(PTC)andthyroid benign lesions.MaxVision conventional immunohistochemistry of frozen remaining tissue was served as control.ResultsMaxVision one-step rapid immunohistochemical staining technique could be completed in 20 minutes.The positive localizations of three markers detected by rapid immunohistochemistry were similar to conventional immunohistochemistry, in general.The expression of CK19 was located in cytoplasm and cellular membrane.Gal-3 and HBME-1 were mainly detected in follicular luminal border and/or surface of papilla. The staining intensity in rapid immunohistochemistry was stronger than that in conventional immunohistochemistry. The positive rates of CK19,HBME-1,and Gal-3 by rapid immunohistochemistry in frozen sections were: 0 (0/28),10.7 ％ (3/28),0 (0/28),respectively,for benign lesions (nodular goiter,Hashimoto thyroiditis,thyroid adenoma); and 94.9 ％(37/39),92.3 ％ (36/39),92.3 ％ (36/39),respectively,for PTC.The expression of three markers between thyroid benign lesions and PTC had a significant difference (x2 =59.326,55.861,44.605,all P ＜ 0.001).In benign lesions,the rate of same case with two and more positive markers was 0,while in PTC it was 100 ％ and significantly different (x2 =67.000,P ＜ 0.05).ConclusionMaxVision one-step rapid immunohistochemical staining technique could be applied in intraoperative frozen section diagnosis.Detecting CK19,HBME-1,and Gal-3 expression in intraoperative frozen section has an auxiliary value for diagnosis of PTC.
