To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective To evaluate the perfectibility of colposcopy directed biopsy for the diagnosis of cervical intraepithelial(CIN)through cervial conization by loop electrosurgical excision procedure(LEEP).Methods Biopsy by colposcopy and biopsy after LEEP were analyzed retrospectively in 108 cases of cervical intraepithelial neoplasia to study the related factors of affecting the coincidence rate.Results Comparison of pathological hanges following both LEEP and colposcopy showed that 69 cases were the same,24 upgrade,and 15 downgrade.Conclusion LEEP is a kind of effective and perfect method for the specific diagnosis and treatment of CIN.Colposcopically directed biopsy has its limitations.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

Objective To observe the clinical efficacy of point injection at Xialiao point (BL 34) for levator ani syndrome. Methods A hundred levator ani syndrome patients were randomly allocated to a treatment group and a control group, 50 cases each. The treatment group received point injection at Xialiao point (BL 34) and the control group was intervened by biofeedback therapy. The Visual Analogue Scale (VAS), component scores of the MOS 36-item Short-From Health Survey (SF-36), anal resting and squeeze pressures were recorded in the two groups before and after the treatment. The therapeutic effects and therapy costs were compared between the two groups.Results The VAS, component scores of SF-36, anal resting and squeeze pressures were significantly changed after intervention in the two groups (P<0.05). After treatment, the VAS, a part of the SF-36 score [physiological function (PF), body pain (BP), vitality (VT) and social function (SF) scores], anal resting and squeeze pressures in the treatment group were significantly different from that in the control group (P<0.05). The total efficacy rate was 88.0% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The therapy costs in the treatment group were (327.31±13.42) RMB and (408.45±21.56) RMB in the control group, and the difference was statistically significant (P<0.01).Conclusions Point injection at Xialiao point (BL 34) is an effective method for levator ani syndrome.

Objective:To evaluate the bone alteration subject to remodeling and analyze the esthetic result following immediate implant placement of incisors.Methods:In this study,20 patients (1 3 women,7 men)were involved,who needed implants for incisors of maxilla.The patients received 23 im-mediate implants totally.On the day of surgery and 6 months after the implants were placed,Cone beam CT (CBCT)was taken.The thickness of the alveolar ridge and the vertical change of marginal bone levels onthe mesial and distal aspects of theimplants were measured using the computer software (Planme-caRomexis Viewer 3.6.0.R).The evaluation of esthetic result by labial convexity score (LCS)and pa-pilla index score (PIS)were analyzed pre-operation and one year after the final crown was delivered.The statistics with paired-t test for the measurement data and Willcoxon test for rating data were done by SPSS 20.0.Results:The survival rate in the two-year follow-up was 1 00%.The measuring point 1 (MP1 ), MP2,MP3 and MP4 (0,2,4,6 mm apical to the implant platform,respectively)got significant altera-tions after 6 months of the follow-up.These differences were statistically significant (P<0.05 ).The major alteration happened at MP1 and MP4,which got (-0.89 ±2.06)mm and (-0.75 ±1 .28)mm reduction of the alveolar,respectively.The marginal alveolar ridge resorption was (-0.42 ±1 .24)mm and(-0.91 ±1 .96)mm for Ankylos System and Replace System,respectively,and the difference was not statistical significant .The esthetic results were quite acceptable.Before treatment,1 8 incisors rated 3 for LCS,and 2 incisors rated 4 for LCS;after final restoration,only 5 incisors rated 3 for LCS,and 1 4 incisors rated 2 for LCS.Before treatment,1 5 incisors rated 3 for PIS;after final restoration,1 3 incisors rated 3 for PIS.There was no statistically significant difference for the PIS pre-operation and 1 year after final restoration,while there was statistically significant negative change for LCS.Conclusion:Even fol-lowing the proper surgical technique,the alveolar ridge wall still can’t be maintained after immediate im-plant placed in fresh socket of incisors.The inter-dental papilla could be well maintained,while due to the remodeling of labial bone,labial convexity will inevitably collapse.Therefore immediate implant still has esthetic risk.

Objective:To study the related factors of severe acute radiation-induced lung injury (SAR) caused by IMRT and concurrent chemotherapy for non-small cell lung cancer. Methods:We retrospectively analyzed the data of 2 323 non-small cell lung cancer pa-tients who underwent IMRT radiotherapy and concurrent chemotherapy at the Department of Radiotherapy of Tianjin Medical Univer-sity Cancer Institute and Hospital from January 2010 to January 2014. We analyzed the clinical factors and parameters that affect dose by univariate and multivariate analysis. Results:A total of 2 323 patients enrolled and 1 241 cases suffering from acute radiation-in-duced lung injury with the rate of 53.4%. Only 185 cases suffered from SARP with a rate of 7.96%. Univariate analysis showed that the gender, histopathological type, total radiation dose, V5 (%), and average dose rate are not related to SARP (P>0.05). By contrast an age of>60 years, 1%predicted FEV, docetaxel+carboplatin/cisplatin chemotherapy, V20 (%), V30 (%), and mean lung dose (MLD) are sig-nificantly related to SARP (P<0.05). Multivariate analysis showed that a patient age of>60 years, docetaxel+carboplatin/cisplatin che-motherapy, V20 (%), and V30 (%) are the independent risk factors of SARP. Conclusion:Among the non-small cell lung cancer patients undergoing IMRT radiotherapy and concurrent chemotherapy, further attention should be given to elderly patients, patients receiving docetaxel and platinum chemotherapy, as well as V20 and V30 with high doses. The necessary preventive treatment should be given to reduce the incidence of SARP, improve the quality of life of patients, and reduce the incidence of respiratory failure and mortality.

Objective To investigate the relationships between fetal neural tube defects (NTD) and maternal plasma homocysteine (Hcy) level,total nitric oxide synthase (NOS) and inducible NOS (iNOS) activity.Methods A total of 28 pregnant women with clinically or prenatal ultrasound diagnosed NTD offspring in Shihezi City and its surrounding areas of the Xinjiang Uygur Autonomous Region from January 6,2008 to May 23,2011 were enrolled as NTD group.Another 41 normal pregnant women,matched in corresponding area and period,were enrolled as the control group.The plasma level of Hcy was determined by rate method,and the activities of total NOS and iNOS were detected by spectrophotometry.Linear correlation analysis and t-test were used as statistical method.Results The plasma level of Hcy in NTD group was higher than that in the control group with statistically significant difference [(15.2±7.9) μmol/L vs (8.4±3.7) μmol/L,t=4.269,P＜0.01].The activity of total NOS was lower in the NTD group than that in the control group [(20.0±9.0) U/ml vs (26.0±4.1) U/ml,t=3.258],so was the activity of iNOS [(7.5±2.9) U/ml vs (12.0±4.5) U/ml,t=4.670],the differences were statistically significant (both P＜0.01).Linear correlation analysis showed a negative correlation between the level of Hcy and the activity of total NOS (r=0.325,P＜0.01),but no correlation was found with iNOS (r=0.205,P＞0.05).Conclusions High level of Hcy and low activity of NOS and iNOS might be correlated with fetal NTD.

Objective To review the clinical experience of diagnosis and treatment of the congenital diaphragmatic hernia in newborn infants. Methods Thirty-three neonates were diagnosed having congenital diaphragmatic hernia in our hospital from Jan. 1,2004 to Sept. 30, 2009. The clinical data was retrospectively reviewed. Results 21 cases were treated surgically and 17 survived, while 4 cases died. The main cause of death was congenital pulmonary dysplasia. Another 12 cases refused to accept surgical treatment and they all died, one died shortly after he was born. Four cases who had been diagnosed by prenatal ultrasonography were survived. Conclusion The mortality of congenital diaphragmatic hernia in neonates was still high. Prenatal diagnosis of the congenital diaphragmatic hernia is very important and the cooperation between the obstetrics, neonatology and cardiothoracic surgery will improve the survival rate of congenital diaphragmatic hernia in newborn infants.
