Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

Objective To evaluate the clinical significance of intercellular space diameters (ISD)of squamous epithelium by light microscopy (LM) in lower esophagus of erosive reflux esophagitis (ERD),non-erosive reflux disease ( NERD), Barrett esophagus (BE) and healthy controls. Methods A total of 21 ERD and 21 NERD patients with reflux symptoms and confirmed with 24-hour esophageal pH monitoring, 13 BE patients diagnosed by gastroscopy and biopsy, and 20 other healthy controls were enrolled in the study.Samples of ERD, NERD and control group were collected at 2 cm above dentate line, and made HE slides in the conventional way. Images for measurement of ICS were acquired with oil lens ( × 1000). ICS of squamous epithelium was quantitatively measured by computer-assisted morphometry. Ten cells were taken for each sample, 10 consecutive ISD for each cell, i.e. 100 ISD for each subject. Mean ISD was calculated.Results Mean ISDs by LM in control, BE, ERD, and NERD groups were 0. 59, 0. 99, 1.29 and 1.06 μm, respectively. The mean ISDs in BE, ERD, and NERD group were much greater than that in control (P＜0. 05). The mean, maximal and minimal ISDs of group ERD were greater than those of NERD and BE (P = 0. 000). However, the ISDs of NERD and BE are of no significant difference ( P ＞ 0. 05 ). The cut-off value of mean ISD for diagnosis of gastro-esophageal reflux disease (GERD) was 0. 85 μm. Diagnostic sensitivity and specificity for ERD, NERD and BE were 89. 1% and 100. 0%, with reference to clinical symptoms, endoscopy and ISDs above the cut-off value. Conclusion Larger ISDs in lower esophagus by using LM will be found in all subgroups of GERD, including ERD, NERD and BE. Increased ISDs may be one of the markers for diagnosis of ERD, NERD and BE.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

This study was aimed to establish a method for simultaneous determination of seven anions and organic acids in Huo-Xue Tong-Luo (HXTL) injection by HPCE. With tartaric acid as the internal standard, separation was performed on an uncoated fused silica capillary (50 μm × 64. 5 cm, 56 cm of effective length). The 14 mmol·L-1 potassium acid phthalate and 0.1 mmol·L-1 hexadecyl trimethyl ammonium chloride were selected for the running buffer solution (pH 5.6). The separation voltage was -16 kV. The detection wavelength was set at 210 nm. The column temperature was maintained at 25 ℃ . The sample was injected at 50 mbar×4 s. The results showed that
calibration curves of chloride ion, sulfuric acid root ion, formate ions, malic acid, succinic acid, iodate ion and acetic acid ions showed good linear relationship 41.4-248.2 μg·mL-1 (r = 0.999 3), 12.5-74.8 μg·mL-1 (r = 0.999 8), 18.2-109.1 μg·mL-1 (r = 0.999 8), 20.3-121.6 μg·mL-1 (r = 0.999 5), 17.2-103.1 μg·mL-1 (r=0.999 1), 17.6-105.6μg·mL-1 (r=0.999 6), 51.6-309.6μg·mL-1 (r=0.999 7), respectively. The average recoveries were 102.6%, 97.3%, 102.2%, 99.0%, 99.2%, 97.8%, and 103.4%, respectively. The RSD were 1.7%, 2.0%, 1.6%, 2.6%, 2.1%, 2.9%, and 1.0%, respectively (n = 6). It was concluded that the method was accurate and reproducible. It was suitable for the determination of anions and organic acids in HXTL injection.

To reveal the genetic diversity and genetic structure in Artemisia annua varieties (strains) populations, we detected the genetic polymorphism within and among eight varieties (strains) populations (192 individuals) by the approach of Start Codon Targeted Polymorphism (SCoT). The associated genetic parameters were calculated by POPGENE1.31 and the relationship was constructed based on UPGMA method. The results showed that, using 20 screened primers, a total of 145 bands were produced, of which 122 were polymorphic loci. At species level, there was a high level of genetic diversity among eight varieties (strains) populations (PPB = 84.1% ,H = 0.217 3 and H(sp) = 0.341 9). However, at the variety (strains) population level, genetic diversity was lower, the average of genetic parameters was PPB = 41.9%, H = 0.121 5, H(pop) = 0.186 8. The Nei's genetic differentiation coefficient was 0.441 0, indicate that most of the genetic variation in this species existed within the variety populations. The gene flow (N(m) = 0.633 9) was less among populations, indicating that the degree of genetic differentiation was higher. Genetic similarity coefficient were changed from 0.755 1 to 0.985 7. By clustering analysis, eight varieties (strains) were clustered into two major categories and it was also showed the same or similar genetic background varieties (strains) have a tendency to gather in the same group. Results suggest that, in variety breeding, breeders should strengthen the exchange of bred germplasm and increase mutual penetration of excellent genes, which would broaden the genetic base of A. annua.

Objective To investigate the medical care conducts of community residents of Dongying and analyze the main problem in order to provide the evidence for optimizing the community health service model.Methods Stratified cluster sampling method was used,and 330 community residents in 4 communities were investigated with questionnaire about the medical care conducts.Results Among 330 residents,63％ of them did not attend medical clinics after getting minor illnesses,only 12.7％ of them chose to check up in large hospitals,and 14.2％ went to the community services.However,there were 10.1％ of the population attended private clinics.These medical care conducts were significantly related to gender,age,education level,and the payment patterns (x2 =51.0,106.5,16.3,31.8;P ＜0.05).Health condition has no effect on the residents' medical care conducts (x2 =11.3;P ＞ 0.05 ). Residents with different ages had significantly different influencing factors of choosing medical institution,and different their satisfaction on community service center ( x2 =15.7,44.7 ;P ＜ 0.01 ).Conclusions It should be encouraged to integrate the medical resources in order to establish the effective community services.The charge standards of medical procedures should be restricted by authority policies,and the residents should be guided to attend clinics in an appropriate way with reasonable payment.

OBJECTIVETo investigate the effect of the basic fibroblast growth factor (b-FGF) to regenerate an autologous tissue-engineered cartilage in vitro.

METHODSThe Cells were harvested from the elastic auricular cartilage of swine,and were plated at the concentration of 1 x 10(4) cells/cm2 , studied in vitro at two different media enviroments: Group I contained Ham's F-12 with supplements and b-FGF, Group II contained Ham's F-12 only with supplements. The passage 2 cells (after 12.75 +/- 1.26 days) were harvested and mixed with 30% pluronic F-127/Ham's F-12 at the concentration of 50 x 10(6) cells/ml. It was injected subcutaneously at 0.5 ml per implant. The implants were harvested 8 weeks after the vivo culture and examined with the histological stains.

RESULTSThe chondrocytes displayed morphologically similar to the fibroblasts in the media containing basic-FGF. The number of cell doublings (after 12.75 +/- 1.26 days) in vitro culture was as the following: Group I, 70; Group II, 5.4. Eight 8 weeks after the vivo autologous implantation, the average weight (g) and volume (cm3) in each group was as the following: Group I, 0.371 g/0.370 cm3 Group II, 0.179 g/0.173 cm3 (P < 0.01). With the b-FGF in vitro culture, the cells were expanded by 70 times after 2 weeks. Histologically, all of the engineered cartilage in the two groups were similar to the native elastic cartilage.

CONCLUSIONThese results indicate that the basic-FGF could be used positively to enhance the quality and quantity of the seeding cells for the generation of the well-engineered cartilage.
