OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Mycoepoxydiene is a novel antitumor agent extracted from marine lignicolous fungi HLY-2, which is Diaporthe phaseolorum by molecule identification. The medium optimization for mycoepoxydiene by orthogonal design and the comparison of submerged fermentation and solid state fermentation were studied. The rusult is that the maximal yield of the compound is 543mg/L, which is 43 times compared to the customary half-seawater PD medium and 15 times to the best submerged condition. This optimum culture medium included potato 250g/L, seawater 300mL/L, glucose 30g/L, lactose 50g/L, KH_ 2 PO_ 4 0.65mmol/L and (NH_ 4 )_ 2 SO_ 4 1g/L in the solid state condition. Differentiation analysis between submerged and solid state fermentation, and antitumor activity of these ferment products were also studied. The antitumor activity of products of the optimum medium approached the pure compound.

Three hundred and twenty-one bacteria strains were obtained from rice leaves,stem,root tissue and paddy field soil,of which the number of strains which can inhibit mycelium of Magnaporthe grisea growth markedly was fifty-seven through fermentation in 2.0 mL Eppendorf tube,and among these fifty-seven strains,five strains were strongly antagonistic to Magnaporthe grisea.These five strains was identified for their morphologic,physiological and biochemical characteristics,and the results showed that one strain(No.156)was bacillus subtilis,two strains(No.171 and No.177)were Bacillus pumillus and two strains(No.192 and No.279)were Bacillus ploymyxa.

Objective To investigate the effects of Helicobacter priori (H.prlori) strains from the patient with gastric cancer on the expression of DNA mismatch repair (MMR) genes in AGS cells in vitro. Methods AGS cells were co-cultured with ten strains of H.prlori from five patients with gastric cancer and five patients with gastritis respectively.The expressions of DNA MMR genes (hMSH2 and hMLH1) in mRNA and protein levels were determined by RT-PCR and Western blot.The enteropathogenic E.coli served as a bacterial control.Results E.coli and H.priori strains from gastritis have no effects on the expression of hMSH2 and hMLH1 in both protein and mRNA levels on the whole,while all the H.prlori strains from gastric cancer reduced expression levels of hMSH2 and hMLH1.Conclusions There are different effects between H. prlori strains from gastric cancer and those from gastritis on DNA MMR in AGS cell line,indicating that infec- tion of some H.prlori strains might lead to the inhibition of DNA MMR,and that in turns increases the risk of gastric carcinogenesis during chronic H.prlori infection.

Presently, there are many issues in traditional Chinese medicine (TCM) decoction, such as the uncertain sources of TCM, the lack of reminder for medication taboo, the nonstardard herb operation, and difficult supervision, etc. A digital service system of TCM decoction was established to solve the problems mentioned above. The digital service system mainly includes automatic coding for checking in & out, drug medication taboo database, digital operation in decoction, distribution through 2D code, the corresponding application for mobile phone, and the information supervision platform for TCM decoction. The digital service system of TCM decoction can track the quality & duty of the pieces, remind decoction medicine contraindications, improve the standard operation process of decoction, develop decoction distribution & tracking through cell phone, save the waiting time, and hence provides a new supervising method for TCM decoction. The digital service system of TCM decoction solves the key issues for the formula, operation, delivery and supervision of TCM. In the same vein, this system will expand the market share of TCM decoction and promote the development of TCM.

To explore the correlation between the ecological factors and the contents of podophyllotoxin and total lignans in root and rhizome of Sinopodophyllum hexandrum, podophyllotoxin in 87 samples (from 5 provinces) was determined by HPLC and total lignans by UV. A correlation and regression analysis was made by software SPSS 16.0 in combination with ecological factors (terrain, soil and climate). The content determination results showed a great difference between podophyllotoxin and total lignans, attaining 1.001%-6.230% and 5.350%-16.34%, respective. The correlation and regression analysis by SPSS showed a positive linear correlation between their contents, strong positive correlation between their contents, latitude and annual average rainfall within the sampling area, weak negative correlation with pH value and organic material in soil, weaker and stronger positive correlations with soil potassium, weak negative correlation with slope and annual average temperature and weaker positive correlation between the podophyllotoxin content and soil potassium.

Objective: To observe the clinical efficacy of filiform fire-needling plus continuous passive motion (CPM) therapy for frozen shoulder. Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. Patients in the control group received celecoxib capsule plus CPM, while those in the observation group received filiform fire-needling plus CPM. The whole course of treatment lasted for 2 weeks in both groups. The visual analog scale (VAS), Constant-Murley score (CMS) and range of motion of shoulder joint were measured for therapeutic efficacy evaluation. Results: The total effective rate was 91.7％ in the observation group, higher than 72.2％ in the control group, and the between-group comparison showed statistical significance (P<0.05). After treatment, the VAS scores in the two groups dropped significantly, the CMS as well as the range of motion including abduction, forward flexion and extension were all increased significantly, and the intra-group comparisons showed statistical significance (all P<0.05). The betweengroup comparisons showed the improvements in these items in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Filiform fire-needling plus CPM can produce more significant efficacy than celecoxib capsule plus CPM for frozen shoulder; it can alleviate pain, improve shoulder function and restore joint range of motion in such patients.

OBJECTIVETo investigate the molecular characteristics and genotype of Japanese encephalitis virus (JEV) found in vector mosquitoes in Zhejiang province from 1982 to 1983.

METHODSA total of 3188 mosquitoes were collected in Dinghai district and Yiwu city in Zhejiang province, during year 1982 and 1983. The virus was isolated by C6/36 cell, and then identified by hemagglutination inhibition test. The isolated strains were activated in year 2011, and plaque forming unit (PFU) were applied to test the virus titer. The suckling rats were tested under intracranial inoculation, where PrM and E genes were amplified and sequenced. Their nucleotide and amino acid sequences were analyzed and compared with the JEV vaccine strain SA14-14-2 and the JEV isolated in Zhejiang province during 2007 and 2010; and phylogenetic tree were constructed by bioinformatic software.

RESULTSFrom the 3188 mosquitoes captured, eleven virus strains were isolated and found to be able to cause cytopathogenic effect (CPE) in C6/36 cells within 72 hours. Virus titer ranged from 2.5 to 6.47 lg PFU/ml. The suckling rats would die within 72 hours since the inoculation. The phylogenetic analysis with the PrM and E genes showed that the JEV isolated in Zhejiang during 1982 and 1983 belonged to genotype III; while the JEV isolated in Zhejiang during 2007 and 2010 belonged to genotype I. The analysis of E genes from 5 isolated strains found that the homology of nucleotide sequence was over 98.9%, and the homology of amino acid sequence was over 99.8%. The compare between the 5 virus strains and the vaccine strain SA14-14-2 found 10 common amino acid variation sites, and showed that the homology of nucleotide sequence was over 97.7%, and the homology of amino acid sequence was 99.2%. The compare between the 5 virus strains and the JEV isolated in Zhejiang during 2007 and 2010 found a 87.7% - 87.9% nucleotide homology and an over 98.8% amino acid homology.

CONCLUSIONThe JEV isolated from the mosquitoes in Dinghai district and Yiwu city between year 1982 and 1983, were genotype III.
