Objective To observe the efficacy of anatomical locking plate combined with anchor nail internal fixation and clavicular hook plate in the treatment of Neer Ⅱ distal clavicle fracture and their impact on shoulder function.Methods Eighty patients with Neer Ⅱ distal clavicular fracture treated in the Eighth People's Hospital in Shanghai from January 2015 to December 2016 were divided into observation group and control group,each group 40 cases.The observation group was treated with anatomical locking plate combined with anchor nail,the control group was treated with clavicular hook plate.The efficacy,operation time,intraoperative blood loss,fracture healing time,postoperative hospital stay,shoulder function score and incidence of complication were observed in the two groups.Results The excellent rate was in the observation group was higher than that in the control group (97.50%(39/40) vs.80.00%(31/40),χ2=2.477,P<0.01).The operation time,intraoperative blood loss and postoperative hospital stay in the observation group and the control group were (53.36±4.69) min vs.(54.19±5.13) min,(69.65±7.17) ml vs.(70.38±8.29) ml,(7.39±1.64) d vs.(7.42±1.97) d,the differences between the two groups had no statistical significance (P>0.05);the fracture healing time in the observation group was longer than that of the control group ((23.65±2.19) w vs.(26.9±3.46) w,P<0.01).The shoulder joint Constant-Murley score in the observation group was (86.02±5.19) points,control group (68.46± 6.94) points,the difference was statistically significant (P<0.01).Observation group showed 2 cases of pain around acromion,the incidence rate of complications was 5.00%(2/40);7 cases in the control group had pain around acromion,2 cases suffered from impingement syndrome and 1 cases had delayed union,the incidence rate of complications was 25.00% (10/40).Conclusion Anatomical locking plate combined with anchor nail internal fixation is effective in the treatment of Neer II distal clavicle fracture.It has the advantages of fast fracture healing,good functional recovery of shoulder joint and less complications.

Objective To investigate the expression of FHITmRNA and WWOXmRNA in human breast cancer tissues and its relation to clinicopathological and other molecular parameters. Methods With reference to the expression of ?-actin,the expression of FHITmRNA and WWOXmRNA was determined by reverse (transcription)-polymerase chain reaction(RT-PCR) in 51 breast cancer and adjacent breast tissue, and (semi-quantitative) analysis of band densities was performed. The protein expression of estrogen receptor(ER), progesterone receptor (PR), Her-2 gene in the 51 breast cancer lesions was detected by (immunohistochemical) method. Results FHITmRNA and WWOXmRNA expression was significantly different in 54 breast cancer tissue compared to adjacent breast tissue (P0.05); of FHITmRNA and WWOX mRNA was related to axillary lymph node metastasis (P

Objective To investigate the efficacy of pancreatic duct guidewire pre-occupying in ERCP with difficult biliary cannulation.Methods During a four-year study period from June 2008 to June 2012,a total of 3505 patients were included in this retrospective analysis.Initial biliary cannulation method consisted of single-guidewire technique for up to 5 attempts,followed by double-guidewire technique when repeated unintentional pancreatic duct cannulation had taken place.Pre-cut papillotomy technique was reserved for when double-guidewire technique had failed or no pancreatic duct cannulation had been previously achieved.Biliary cannulation success and post-ERCP complication rate were compared.Results Single-guidewire technique was characterized by statistically significant higher success rate (93.4％),compared with the double-guidewire technique (54.8％,P ＜0.001),pre-cut failed double-guidewire technique (81.3％,P ＜0.001) or precut as first step method (84.6％,P =0.011).Pre-cut failed double-guidewire technique and pre-cut as first step method offered a statistically significantly more favorable outcome compared with the double-guidewire technique (both P ＜ 0.001).The incidence of post-ERCP pancreatitis did not differ in a statistically significant manner among the four methods.Numbers of patients who got bleeding in pre-cut papillotomy technique and sphincterotomy after successful single-guidewire technique were 5 and 2 respectively.One case of perforation was recorded using pre-cut papillotomy technique.There was no procedure-related mortality within 30 days.Conclusion Although double-guidewire technique success rate proved not to be superior to singleguidewire technique or pre-cut papillotomy,it is considered highly satisfactory in terms of safety in order to avoid the risk of a pre-cut when biliary therapy is necessary in difficult-to-cannulate cases.

This article was aimed to study the physiological mechanisms in frozen storage to reduce early bolting of Angelica sinensis. By analyzing the root soluble sugar, soluble protein, MDA content changes before and after -10oC processing of the Angelica sinensis seedlings of different size from different sources , the physiological mechanisms in frozen storage reducing early bolting of A . sinensis had been studied. The results indicated that the greater seedlings , the higher content of soluble sugar , lower protein content and higher MDA . There were no obvious differences on the soluble sugar , soluble protein and MDA content of the same size seedlings from different sources . After -10oC freezing , the content of soluble sugar and protein in the seedlings with the same size were decreased. Meanwhile, the content of MDA was increased. It was concluded that the content of soluble sugar, soluble protein and MDA were obviously related to the size of Angelica sinensis seedlings from the same source before and after low temperature process .

Objective To evaluate the effect of external fixation at first stage combined with intr-amedullary nail internal fixation at second stage on treating open fracture of tibial shaft. Methods A total of 80 patients with open fracture of tibial shaft treated in our hospital from April 2016 to April 2017 were selected as the subjects. According to the treatment methods,they were divided as control group and obser-vation group with 40 cases in each group. The control group was given intramedullary nail internal fixation and the observation group was given external fixation at first stage combined with intramedullary nail inter-nal fixation at second stage. The general operation condition of the two groups was observed and the frac-ture reduction,healing and Rasmussen score were compared between the two groups. The difference of the circumference and pain degree between the two groups after 1,3 and 7 days were compared. Results The operative excellence rate of the observation group was significantly higher than that of the control group, and there was no difference in circumference and pain between the two groups after 1 day. The circumfer-ence and pain in the observation group was lower than that of the control group after 7 days postoperative-ly,and there was no difference in the Rasmussen score between the two groups after 1 month. The Rasmus-sen scores in the observation group were higher than those in the control group after 3 and 6 months post-operatively. The healing time and the time of callus formation in the observation group were shorter than those in the control group. Conclusion External fixation at first stage combined with intramedullary nail-ing internal fixation at second stage has better therapeutic effect on treating open fracture of tibial shaft.

Objective:The occurrence of numerous tumors, particularly classical Hodgkin's lymphoma (CHL), is related with Ep-stein-Barr virus (EBV) infection. However, the incidence of CHL and its association with EBV varies significantly with ethnicity, geo-graphic location, sex, and age. This study investigated the association of EBV infection with CHL in Northern Chinese Han population. Methods:EBV-encoded small RNA (EBER) was detected in 136 cases of CHL through in situ hybridization. Results:A total of 37 cas-es were EBER positive (28%). The mixed cellularity (MC) subtype had the highest positive EBER rate of 49%(23/47;P<0.001), fol-lowed by lymphocyte-rich subtype with 30%(3/10), nodular sclerosis (NS) subtype with 14%(10/73), and 1ymphocyte depletion with 0%(0/2). Our study identified a single age distribution in the third decade. Moreover, NS subtype showed an evident single peak in the third decade. However, MC subtype had a lower peak in the fifth decade. The incidence of EBER showed a bimodal age distribution with two peaks in the first and fifth decades (21.6%and 24.3%, respectively). Conclusion:CHL in Northern Chinese Han population was associated with EBV infection, particularly the MC subtype.
