Chinese herbal formulas can well present the characteristics of traditional Chinese medicine (TCM) with their simple, convenient, inexpensive and effective uses. However, due to the high cost of production, manufacturing pharmacies inside the hospital closed down one after another, which rendered the difficult situation of developing preparation of Chinese herbal formulas. The Pudong New Area of Shanghai, as a pilot region for comprehensive reforms on national development of TCM, vigorously explores the standardized research on and application of hospital-made Chinese herbal formulas. The Health Bureau of the Pudong New Area, based on the Shuguang Hospital, has established a clinical evaluation center for hospital-made Chinese herbal formulas. Through screening, manufacturing, quality control, unified allocation, and standardized clinical evaluation, the clinical evaluation center has summarized its experience on these processes.

Abstract: Objective To detect the polymorphisms of drug resistance-related genes pvcrt-o and pvmdr1 of Plasmodium vivax in lazan city in the China-Myanmar border, in order to guide the treatment plan of Plasmodium vivax. Methods A total of 48 Plasmodium vivax samples were collected from Lazan in the China-Myanmar border in 2007, and fragments of pvcrt-o and pvmdr1 genes were amplified by PCR and sequenced. The sequences were aligned with the Salvador I (Sal-I) strain reference genome sequences to determine the presence of SNPs. Results The target fragments of pvcrt-o gene were amplified from 39 Plasmodium vivax samples, while pvmdr1 genes were amplified from 40 samples. Amongst them, 25 samples had AAG insertion before the 10th amino acid (K10 insertion) of pvcrt-o gene, accounting for 64.1%. Non-synonymous mutations were detected at three loci of pvmdr1 gene (T958M, Y976F, and F1076L), the mutation rates were 100%, 22.5%, and 55.0%, respectively. There were three haplotypes of pvmdr1 gene, of which the triple mutant 958M/976F/1076L accounted for 22.5% (9/40), the double mutant 958M/Y976/1076L accounted for 32.5% (13/40), and the single mutant 958M/Y976/F1076 accounted for 45.0% (18/40). The proportion of strains with pvcrt-o and pvmdr1 gene mutation is 63.16%, which is significantly different from those only with pvmdr1 mutation. Conclusions The proportion of pvcrt-o and pvmdr1 gene mutation of 48 Plasmodium vivax isolates is high in the China-Myanmar border, and there is a certain degree of correlation between the two gene mutations. To assess changes in Plasmodium vivax drug resistance in this region, it is required to improve the surveillance of these two molecular markers.

Objective In order to analyze the variation of HA genes of influenza viruses (H1N1) by being compared with the vaccine strain A/California/07/2009(H1N1) recommended by WHO ,influenza viruses (H1N1) isolated from 2009 to 2014 were selected to do this study .Methods According to the different isolating time and place ,47 strains of H1N1 collected from 2011 to 2014 were selected .Then the 47 strains′ nucleotide sequence of HA genes which were sequenced in the study and other 25 se‐quences of HA genes which were sequenced in 2009 were collected .Nucleotide and amino acid sequences were analyzed by using molecular biology software ,and the phylogenetic trees were drawn .Results A total of 72 strains isolated from 2009 to 2014 were closely related to the vaccine strain A/California/07/2009(H1N1) ,the nucleotide variance and amino acid variance between the 72 strains were 0-2 .7% and 0-3 .1% respectively .Compared with the vaccine strain A/California/07/2009(H1N1) ,the nucleotide variance and amino acid sequence variance were 0 .4% -2 .4% and 0 .9% -3 .1% respectively .The amino acids sequence indicated that ,although the variance was increased by years ,the H1N1 viruses were still showed characteristics of low pathogenic influenza viruses .It was also found that there were 9 strains lost their potential glycosylation site at HA protein site 481 in 2009 ,while in 2013 there were 6 strains got new potential glycosylation sites at HA protein site 162 .Conclusion The vaccines (H1N1) recom‐mended by WHO was still protective to people in Chongqing .But as time goes by ,antigen drift may occur in some new antigenic drift strains and the routine monitoring of influenza viruses should be continued .

We describe two cases in which a forceps imprintdeveloped in the AcrySof ReSTOR IOL optic whileinserting these IOLs into the cartridge with straightclamping forceps. In case 1 ,the AcrySof ReSTOR IOL wasexplanted and observed under scanning electronmicroscopy (SEM). The SEM showed that the stepdesign of ReSTOR Multifocal IOL was well maintained. Incase 2, visual acuity, contrast sensitivity and wavefrontmeasurements were performed and no specific changeswere found. Strong evidence does not exist that suggeststhe on-axis forceps imprint can significantly compromisevisual acuity.

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.
