A total of 12 775 SSRs were identified from Scutellaria baicalensis Georgi genomic database, accounting for 2.56% of the total genomic sequences. The result showed that S. baicalensis SSRs were based on 68.32% dinucleotide and 18.63% trinucleotide repeats; CT/GA and TTC/GAA were predominant in the dinucleotide motifs and the trinucleotide motifs respectively. Nine primers were selected to produce highly reproducible SSR bands and were used in studying the genetic diversity of S. baicalensis, 50 individuals from ten populations. 68 SSR polymorphic loci were detected, these loci were polymorphic and displayed 4 to 12 alleles per locus with a mean number of 7; the effect number of alleles was 3. Expected heterozygosities were 0.6 and were far more greater than the average in dicotyledonous plants. PIC (polymorphism information content) was 0.72, Shannon's information index was 1.32, these all proved that S. baicalensis had a high genetic diversity in general. Genetic differentiation among population Gst was 0.131, genetic variation among population accounted for 13.1% and genetic variation within population accounted for 86.9%. The cluster analysis showed that 10 populations S. Baicalensis were classified into 2 groups, but it was not associated with geographical distribution.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.

METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.

RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.

CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

Objective To investigate the antimicrobial resistance of clinical isolates from a hospital in Chongqing during one year according to CHINET project.Methods Disc diffusion test (K-B method) was employed to study the antimicrobial resistance. WHONET5 was used for data analysis.Results In one year period from 2004 to 2005,690 non-duplicate isolates were collect- ed.Enterobacter isolates showed the lowest resistance rate to imipenem and meropenem.About 37.5% of E.coli and 31.4% of K.pneumoniae isolates produced ESBLs,respectively.All ESBLs-producing strains were susceptible to imipenem and mer- openem.About 37.2%,39.4% and 48.9% of P.aeruginosa isolates were resistant to imipenem,meropenem and ceftazidime, respectively.Pandrug-resistant (PDR) P.aeruginosa was isolated from our hospital.All strains of A.baumannii were sus- ceptible to imipenem and meropenem.About 37.7% of A.baumannii were resistant to cefoperazone-sulbactam.Twenty-nine strains showed the same resistant pattern among non-susceptible strains of A.baumannii,mainly derived from 2 clones by PFGE analysis.Conclusions The surveillance results suggest that prevalent strain resistant to cefoperazone-sulbactam may pres- ent in some ICUs.Resistance rate to cefoperazone-sulbactam increased significantly.

This study was to report the effect of Tangshen Formula on phospholipids metabolism in diabetic nephropathy patients. A normal phase-HPLC-TOF/MS method was used in this study for the determination of seven species of phospholipids in human plasma. Then, the concentration changes of potential phospholipids biomarkers were discussed in diabetic nephropathy phase III and phase IV patients among different groups, including before and 3, 6 months after administration of Tangshen Formula. Significant increases of PE750, PI885, PC792, PC826, PC830, PC854 and PC802 levels were observed 6 months after administration of Tangshen Formula and conventional western medicine, as well as a decrease of LPC540 level, when compared with those before medication. Concentrations of all the potential phospholipids biomarkers showed a tendency towards normal levels; however, both the improvement degree and onset time of these compounds were not same. Additionally, Tangshen Formula treatment based on conventional western medicine treatment was more efficient in adjusting the levels of these compounds when compared with western medicine treatment alone, especially for the phase IV patients. These results indicated that Tangshen Formula was capable in regulating and improving phospholipids metabolism in diabetic nephropathy patients, which may be related with the direct or indirect inhibition of protein kinase C pathway and the corresponding reduction of phospholipase A2 activity. Therefore, Tangshen Formula may be used as an effective drug for diabetic nephropathy therapy, at least as an adjunctive therapeutic drug.

AIM: To observe the clinical effect of combined cataract and primary open-angle glaucoma underwent phacoemulsification and glaucoma drainage device implantation. ·METHODS: We selected in our hospital from January 2014 to February 2016, 42 cases (42 eyes) with primary open-angle glaucoma with cataract. According to random number table method, all of the patients were randomly divided into two groups, control group and study group. In control group, 21 patients ( 21 eyes ) underwent trabecular resection combined phacoemulsification;in study group patients, 21 patients ( 21 eyes ) , underwent EX-PRESS glaucoma drainage device combined phacoemulsification. Compared parameters included postoperative complications and filtering bleb, visual acuity, intraocular pressure ( IOP ) and other clinical indicators between two groups. ·RESULTS: Preoperative IOP of two groups was no significantly different (P>0. 05). Postoperative IOP at each time point was significantly lower than before treatment (P<0. 05). At 1d, 1 and 4wk after treatment, IOP of the study group was significantly lower than the control group (all P<0. 05); at 12wk after treatment, IOP of the two groups was not significantly different ( P> 0. 05). At 12wk after treatment, surgical success rate of study group was 95%, significantly higher than that of control group 71% (P<0. 05). The postoperative best corrected visual acuity of two groups was no significantly different (P>0. 05). At 12wk after treatment, 21 patients in study group were shown as functional filtering bleb, while in the control group 18 cases was functional filtering bleb. ·CONCLUSION:Using EX-PRESS glaucoma drainage device combined with phacoemulsification in treating cataract with primary open-angle glaucoma is reliable, the curative effect is better than that by trabeculectomy combined with phacoemulsification treatment.
