OBJECTIVE: To review the progress in the content assay methods of sulfate polysaccharide drugs. METHODS: By nonsuiting the literature at home and abroad in recent years, the content assay methods of sulfate polysaccharide drugs, including direct staining method, acid-degradation color-development method, photometric titration, liquid chromatography and biopotency, are introduced and compared. RESULTS AND CONCLUSION: The specificity, precision and accuracy, feasibility of practical operation and the instrument cost of the five methods are different. But high performance liquid chromatography method with good specificity, high sensitivity, and accuracy can give more accurate result of the drug content. It is more widely applied in the determination of drug content, so it will be the main method of content assay in the future.

The questionnaire and the result of 2010' Hwato Cup National University Students' Acupuncture Manipulation Skills Competition were analyzed in this paper. It was showed that the competition achieved the significant effects of enhancing acupuncture manipulation skills for the university students and promoting the standardization on teaching acupuncture manipulation skills. The teachers and students were not very satisfied with the current acupuncture manipulation skill education. In the competition, only the item of reciting the classics achieved more than 90 scores, which just displayed the memory ability. The results of the manipulation competition were generally not very high. It is suggested that concerning to teaching acupuncture and moxibustion in the future, the ratio of class time for improving the practice ability on the human body should be increased and the practice on some manipulation techniques such as inserting the needle by holding the needle tip with the pressing hand, reinforcing-reducing technique by twirling and rotating the needle and warming needle technique should be intensified. It is necessary to enhance the interpretation, emphasis and supplementation on the keys and details of some manipulations of acupuncture and moxibustion.

OBJECTIVETo analyse the cartilage erosion related blood biochemical and immune factors in rheumatoid arthritis (RA) and to explore the special influences of Chinese medicine (CM) and Western medicine (WM) on these factors.

METHODSThree hundred and ninety-seven patients, with confirmed diagnosis of active RA, were randomly assigned to the WM group (194 patients) and the CM group (203 patients). The WM applied covered non-steroid anti-inflammatory agents and slow acting medicine; and the CM given included basic remedy and syndrome differentiating medication. Related blood biochemical and immunological indexes were determined before and after treatment to screen out the cartilage erosion related factors and to compare the influence of CM and WM on them.

RESULTSPatients' peripheral red blood cell (RBC) and platelet (PLT) count were changed closely along with their degree of cartilage erosion. RBC count increased in the CM group and PLT count lowered in the WM group after treatment, all showed statistical significance; comparison of the two indexes between the two groups showed that statistical difference presented in RBC but not in PLT count.

CONCLUSIONBoth WM and CM can ameliorate the cartilage erosive factor in RA, but they are acting in different ways.

To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.

AIM: To investigate therapeutic efficiency of amniotic extraction on dry eye in rabbit model induced by topical benzalkonium chloride (BAC).
METHODS: Totally 26 rabbits (26 right eyes) with dry eye model were studied and divided into two groups:group A (control group with PBS eye drops, n = 13) and group B ( amniotic extraction group, n = 13). Another two rabbits were chosen as normal control. The SchirmerⅠ tests ( S Ⅰ t) and corneal fluorescein staining ( FL) were made, and the tear total protein content, amylase activity, lactoferrin, lysozyme contents, goblet cell density were performed in two groups before treatment and 1, 2, 4 and 8 wk after treatment.
RESULTS: There were significant differences in SIT, FL scores, lysozyme activity and goblet cell density among different groups at different time points (P<0. 05). But, there was no significant differences in SⅠt, FL scores, lysozyme activity and goblet cell density between two groups before treatment (P>0. 05). After 8wks' treatment with PBS, the mean differences of the group A showed great changes in SⅠt, lysozyme and goblet cell density compared with those before treatment ( P < 0. 05); but there was no significant differences in FL scores compared with those before treatment (P>0. 05). As for group B, 8wks after treatment, there were statistical changes in SⅠt, FL, lysozyme (P<0. 05); but there was no significant differences in goblet cell density compared with those before treatment ( P > 0. 05). It was evident that statistical differences were observed in S Ⅰ t, FL scores, lysozyme activity and goblet cell density between two groups at each time point (P<0. 05). However, there were no significant differences in total protein, lactoferrin, amylase activity at different time points (P>0. 05). Meanwhile there was no significant differences in total protein, lactoferrin, amylase activity between two groups before treatment ( P > 0. 05 ). But there were significant differences in total protein, lactoferrin, amylase activity between two groups after 4 and 8 wks'treatment (P<0. 05).
CONCLUSION: Amniotic extraction has significant therapeutic effect on the dry eye in rabbit model.

Background Glaucoma is one of the leading causes of blindness worldwide;while the different types of glaucoma is vary from different region. Objective Present study was to survey the prevalence and types of glaucoma among peasants of Uigur adults in Kuche county and offer the basis for the prevent and treatment of glaucoma in Uigur nationanlity. Methods 4191 Uigur peasants aged 40 years or above were collected in Kuche county for the survey of prevalence and types of glaucoma by randomized cluster sampling in March and April of 2009. The subjects were grouped into 40-,50-,60- and ≥70 years groups according to the distribution of age. The disease history of glaucoma, regular eye examination, funds examination and measurement of the anterior chamber depth, gonioscope were performed in the all subjects. Darkroom prone test and mydriasis test were carried out in suspicious glaucomous patients. The depth of periphery anterior chamber was assessed based on van Herick' s criteria, and the width of chamber angle was graded based on Scheie' s method. The standardized training was performed. This survey approved by Xinjiang Medical Ethics Committee, all subjects signed the informed consent before the examination. Results 4191 of 4873 subjects finished all the examinations with the response rate 86%. All the subjects showed a good compliance. The prevalence of glaucoma was 3. 79% , and the prevalence of primary angle-closed glaucoma(PACG) .primary angle-open glaucoma (PAOG) and secondary glaucoma was 2.22% ,0.26% and 1. 31% respectively, showing a significant difference among the different types of glaucoma( P<0. 05). The prevalence of glaucoma was elevated with aging (χ2 - 116. 69 ,P<0. 05) and presented a high rate in male subjects compared with female ones(χ2 = 7. 34, P<0. 05 ). Bilateral blindness was found in 19.75% glaucoma peasants, in which 25.3% glaucoma peasants received anti-glaucoma surgery. The distribution of visual acuity of patients was of significant difference among different age groups(χ2 = 37. 69 ,P<0. 05 ) . Conclusions The prevalence of the glaucoma among Uigur peasants in Kuche county was higher than most area no matter inland or overseas. PACG still is the common type in those people.
