The optimum decoction condition obtained was: adding water (12 times as much as medicine), decocting twice 1.5 hours each time, merging the filtrate, concentrating the merged filtrate into extract with a relative density of 1.20 (measured at 85℃), then adding alcohol slowly, and making the concentration of alcohol in the fluidextract come to 80%. Conclusion: The optimized process is stable and feasible.

Objective To investigate the dose- and time-effects of astragaloside Ⅳ(XGA) on collagen of myocardial fibroblasts in rats.Methods The myocardial fibroblasts of rats were separated by collagenase and trypsinase digestive method,and the cell culture system was established. After XGA in different concentrations and at different time points was administered in fibroblast culture systems,the mRNA expression levels of collagen,matrix metalloproteinases(MMP)-1,-2,-9,tissue inhibitor of metalloproteinase(TIMP)-1 and -2 were measured with reverse transcription-polymerase chain reaction(RT-PCR) test.Results After XGA administration with different doses and at different time points was adminstered,the gel electrophoresis product of RT-PCR in fibroblast culture system expressed the mRNA of type Ⅰ,Ⅲ and Ⅳ collagens,MMP-1,-2,-9,TIMP-1 and -2;but the mRNA expression levels of type Ⅰ,Ⅲ and Ⅳ collagens,TIMP-1 and -2 decreased and the mRNA expression levels of MMP-1,-2,and -9 increased compared to those before XGA administration;the mRNA expression of type Ⅰ,Ⅲ and Ⅳ collagens,MMP-1,-2,-9,TIMP-1 and -2 decreased or increased gradually with the increase of doses and the prolonged time of XGA use.The mRNA expression levels of type Ⅰ,Ⅲ and Ⅳ collagens,TIMP-1 and -2 were negatively related to the doses and action times of XGA(r=-0.927 to -0.637 P= 0 to 0.024);and the mRNA expression levels of MMP-1,-2 and -9 were positively related to the doses and action times of XGA(r=0.672 to 0.962 P=0 to 0.034).Conclusion XGA can markedly reduce the collagen formation of myocardial fibroblasts in rats,and its mechanisms are related to the inhibiting of collagen synthesis and the increase of collagen degradation.

Objective To investigate the management of ankle fracture with surgery and postoperative rehabilitation.Methods The data of 39 inpatients with ankle fracture from 2001 to 2005 were analyzed retrospectively. All patients were treated surgically with open reduction and internal fixation (ORIF) except one medial ankle fracture with closed reduction. All patients were encouraged to perform active and passive range of motion exercises of ankle and the involved limb on the 2nd day after surgery, and partial weight-bearing was allowed at 4th week after surgery.Results No patients had wound-healing problems and deep venous thrombosis, no significant calf muscle atrophy exist at discharging. 29 patients showed excellent ankle joint function and normal gait when the internal fixation was removed at an average 17.9 postoperative months.Conclusion The surgery combined with early rehabilitation used for ankle fracture can improve the recovery of ankle function.

Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

Objective To investigate the prevalence change of drinking water type of endemic fluorosis and the effect of control measures implemented in Huangyuan county of Qinghai province. Methods In 2009, all the endemic fluorosis villages in Huangyuan county were divided into two degrees, light and medium, according to the water fluorosis content before implementing the improving water project, 1 to 2 villages were selected from each degree village, respectively,as monitoring sites, and a total of 3 villages were selected. Source water and tap water samples were collected from each village and water fluoride concentration was determined. Dental fluorosis of all children aged 8 to 12 of monitoring villages was examined, and urine samples were collected by age group of children for determination of urinary fluoride. Clinical skeletal fluorosis of adults over 16 years of age was examined, and 20 copies of adults urine samples were collected to determine urinary fluoride. One village was selected in the 3 villages monitored to conduct X-rays examination of skeletal fluorosis. Water fluoride was tested in accordance with the "Non-metallic Targets Test Methods for Drinking Water" (GB/T 5750.6-2006); urinary fluoride was tested by fluoride ion-selective electrode method (WS/T 89-1996); dental fluorosis was diagnosed using Dean method;adult skeletal fluorosis was diagnosed by "Clinical Diagnostic Criteria for Endemic Skeletal Fluorosis"(WS 192-2008). Results Twelve water samples were assayed, water fluoride was (0.35 ± 0.43) mg/L. The detectable rate of dental fluorosis of 122 children aged 8-12 was 34.43%(42/122) and the geometric mean urinary fluoride was 0.89 mg/L of the 96 children. Of the 834 adults aged 16 and over, clinical detection of skeletal fluorosis was 47.72% (398/836) and geometric mean urinary fluoride was 1.10 mg/L of the 65 cases of adult urine samples assayed, detection rate of X-rays was 31.4% (11/35) in Gangou village of the 35 adults examined.Conclusions In Huangyuan county, water fluoride of the 3 surveyed villages are normal but the endemic fluorosis is still serious. It should strengthen monitoring and analyze the causes and improve prevention measures.

The effects of over-expression of testis-specific expressed gene 1 (TSEG-1) on the viability and apoptosis of cultured spermatogonial GC-1spg cells were investigated, and the immortal spermatogonial cell line GC-1spg (CRL-2053™) was obtained as the cell model in order to explore the function of TSEG-1. We transfected the eukaryotic vector of TSEG-1, named as pEGFP-TSEG-1 into cultured spermatogonial GC-1spg cells. Over-expression of TSEG-1 inhibited the proliferation of GC-1spg cells, and arrested cell cycle slightly at G0/G1 phase. Transfection of TSEG-1 attenuated the transcript levels of Ki-67, PCNA and cyclin D1. In addition, over-expression of TSEG-1 induced early and late apoptosis, and reduced the mitochondrial membrane potential of GC-1spg cells. Moreover, transfection of TSEG-1 significantly enhanced the ratio of Bax/Bcl-2 and transcript levels of caspase 9, and decreased the expression of Fas and caspase 8 in GC-1spg cells. These results indicated over-expression of TSEG-1 suppresses the proliferation and induces the apoptosis of GC-1spg cells, which establishes a basis for further study on the function of TSEG-1.

Objective To compare intrarenal pelvic pressure or endoureteral pressure and infection index between perfusion pump and low pressure of gravity drip during percutaneous nephrolithotomy (PCNL). Methods From 2015 April to 2017 June, 107 patients with ureteral or renal calculus were randomly divided into two groups, among whom 46 cases underwent perfusion pump PCNL and 61 cases underwent low pressure gravity drip PCNL. No statistical significance of preoperative variables was found between the two groups such as age, gender,preoperative status of infection,status of hydrpnephrosis,size and location of stone (P＞0.05).A 5Fr ureteral catheter was positioned into the renal pelvic or ureter,and the intrarenal pelvic or endoureteral pressure was measured by anesthesia monitor during PCNL for all patients.We recorded and compared removing calculus time, postoperative hemoglobin changing, fever rate, procalcitonin abnormal rate, white blood cell counts and calculi clearance rate.Results The average pelvic or endoureteral pressures in the group undergoing perfusion pump and the one undergoing low pressure gravity drip were (22.7±4.6) mmHg VS (29.8±5.3) mmHg and the maximum pressure were (28.8 ±6.56) mmHg VS (50 ±9.25) mmHg.The statistics was significantly different (P＜0.05).Compared with perfusion pump group, the group undergoing low pressure gravity drip had significant differences in fever rate [4.9%(3/61) VS.17.3%(8/46) ], procalcitonin abnormal rate [3.2%(2/61) VS. 15.2%(7/46) ] and white blood cell counts abnormal rate[9.8%(6/61) VS.28.26%(13/46) ] (P＜0.05). However,no significant difference was seen in postoperative hemoglobin changing[(8.3±3.7) g/L VS.(7.2 ± 3.3) g/L] (P＞0.05) and the time of removing calculus [(42.4 ±14.5) min VS (43.6 ±13.5) min] (P＞0.05) .Conclusions Compared with perfusion pump, low pressure gravity drip PCNL maintains lower renal pelvic or endoureteral pressure, which is less than reflux limit during calculi fragmentation. It might be contributed to reduce the postoperative fever rate, white blood cell counts abnormal rate and procalcitonin abnormal rate. Hemoglobin changing and the time of removing calculus show no obvious disadvantage.

OBJECTIVE: To observe the clinical efficacy of minimally invasive acupotomy-injection technique with targeted three-point in the treatment of frozen shoulder. METHODS: From March 2017 to November 2018, a total of 140 patients with frozen shoulder were randomly divided into observation group and control group. The observation group was made up of 70 patients, including 30 males and 40 females; the mean age was (59.2±11.5) years old; the mean duration of disease was (6.76±4.14) months; the observed patients were treated with acupotomy-injection technique with targeted three-point. There were also 70 patients in the control group, made up of 29 males and 41 females; the mean age was (58.9±11.8) years old; the mean duration of disease was (6.65±3.98) months; the control group was treated with the small needle knife therapy. Before treatment and one month after the treatment, the pain levels of both groups were assessed using the short-form McGill pain questionnaire, and the shoulder function was evaluated using the Constant-Murley Shoulder Outcome Scoring. The clinical efficacy of between groups was compared after treatment, and finally, the improvement rate of pain degree was used to evaluate the therapeutic effect of the patients. RESULTS: The PRI, VAS, PPI and total pain scores of frozen shoulder patients in both groups decreased significantly one month after the treatment compared with those before treatment (<0.01). Compared with the control group, the observation group exhibited a more significant decrease in pain scores (<0.01). Furthermore, the shoulder pain, muscle strength, ADL, ROM and total function scores of frozen shoulder patients in the two groups were significantly improved one month after the treatment compared with those before treatment(<0.01). The inter-group comparison indicated that the pain, ADL, ROM and total function scores were improved obviously in the observation group when compared to those in the control group(<0.01), but no remarkable difference was found between muscle strength score and the control group(>0.05). In addition, the markedly effective rate of pain improvement was 70.0% and 45.7% in the observation group and the control group, respectively, meanwhile, the corresponding total effective rate was 97.1% and 84.3%, respectively. CONCLUSIONS The application of acupotomy-injection technique with targeted three-point in the treatment of frozen shoulder shows definite efficacy, easy operation, little pain and high safety. Therefore, it is an ideal method for minimally invasive treatment.
