Chemical constituents of Swertia patens. The whole plant of air-dried Swertia patens was extracted with 90% EtOH. The water extract was suspended in H₂O and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isola- ted and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, ¹H-NMR, ¹³C- NMR).

Objective To explore the operative methods and clinical outcomes in emergency or sube- mergency repair for the complicated tissue defects in hand in first stage applying microsurgical technique. Methods From Jan.,2000 to Aug.,2005,49 emergency cases of complicated hand tissue defects were re- paired in the first stage with replantation,reconstruction,free flaps,combined finger reconstruction and flap transplantation,including 21 cases in mini tissue mass replantation or reconstruction,15 cases in replantation combined with free flap transplantation,8 cases in replantation and reconstruction combined with free flap transplantation,5 cases in combined multiple digits reconstruction with free flap transplantation.The free flap transplantation included the anterolateral femoral flap,the latissimus dorsi myocutaneous flap,the dorsalis pe- dis flap,the media pedis flap and the instep flap.Results All the flaps,the replanted and reconstruceted finger survived uneventfully except for one replanted finger necrosis.45 cases healed in the first stage and the other 4 cases healed in the second stage.During a follow-up from 6 months to 3 years postoperatively,a satis- factory appearance and function of the reconstructed hand was achieved.The excellent and good rate was 85.7% assessed with provisional functional assessment criterion for upper limbs issued by Chinese Society of Hand Surgery.Conclusion The emergency or subemergency repair for the complicated tissue defects in hand has the advantage of short-term treatment and desirable functional outcome.The emergency replantation and reconstruction combined with various flaps or tissue mass can be applied to repair tissue defect in hand in the first stage according to the position and area of the defect along with the technique level of the surgeon, having been proved to achieve desirable clinical outcomes.And the key points leading to a successful operation is the correct treatment for the raw surface of the defects,suitable choice for various flaps,logical design of combination pattern and prevention and timely treatment for vessel crisis.

To have a better understanding on the evolution of Metallosphaera sedula-mediated precipitation and the properties of the precipitate synthesized by this species，a newly identified extremely thermophilic strain (YN23) of Metallosphaera sedula was cultured in the medium containing Fe2+ as energy resouTce under optimal condidons (pH1.5，65℃,0.2g·1-1 yeast extract,30g·1-1 Fe2SO4·7H2O and 170rpm)．XRD，EDS，ETIR and SEM reveal the precipitate obtained from YN23-inoculated flasks to be a mixture of potassium jarosite and ammoniojarosite，with morphological features similar to the latter．Precipitation Was first detected once over 90％ of Fe2+ was oxidized at hour 25 with a peak pH value of 1.92，and was ended when precipitate reached the highest point of 7.9g·1-1 at hour 95 with the lowest pH value of 1.32 in solution．Microbial density underwent a rapid increase along with Fe2+ oxidation and a gradual decrease with precipitate piling up.

OBJECTIVETo evaluate the periodontal conditions in community-dwelling Chinese with diabetes and analyze some related factors.

METHODSA total of 90 (45- to 84- year-old) patients with diabetes, participating in community-based non-communicable diseases management system, were recruited in this study. The examination items on these patients included periodontal measurements performed by pocket probing depth (PPD), attachment loss (AL), sulcus bleeding index (SBI), plaque index (PLI), and blood sugar metabolic level surveillance, as well as structured questionnaire interview.

RESULTSThe prevalence of periodontitis was 100%, while 37.1% was diagnosed as having mild periodontitis, 24.4% with moderate, and 38.5% with advanced periodontitis. The AL level in male was significantly higher than that in female. The periodontal destruction was highly correlated with HbA1C value and affected by some socio-behavior factors based on multinomial logistic model.

CONCLUSIONSThere is a positive correlation between AL and HbA1C level, and AL and HbA1C should be measured regularly. The patients' periodontal inflammation needs effective control. Priority should be given to the low income population and those with little periodontal knowledge for behavior interventions.

This prospective study was conducted to compare risk factors and pregnancy outcomes between women with complete placenta previa and those with incomplete placenta previa diagnosed in mid-pregnancy.The study was carried out from April 2014 to December 2015,during which 70 patients with complete previa and 113 with incomplete previa between 20+0 weeks and 25+6 weeks of gestation were included.Maternal demographics and pregnancy outcomes were compared between the two groups.Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test.Resolution ofprevia occurred in 87.43％ of the studied women.The mean gestational age at resolution was 32.1±4.4 weeks.Incidence of maternal age ≥35 years and incidence of prior uterine operation ＞3 were high in women with complete previa (28.6％vs.8.8％,P=0.003;28.6％ vs.8.8％,P=0.003).Resolution of previa occurred less often in complete previa group (74.3％ vs.95.6％,P=0.001).Women with complete previa admitted earlier (37.3±2.0 weeks vs.38.1±1.4 weeks,P=0.011) and delivered earlier (37.7±1.2weeks vs.38.3±1.4 weeks,P=0.025).Maternal age ≥35 years and prior uterine operation ＞3 increase the risk of complete previa in mid-pregnancy.Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in midpregnancy.What is more,women with complete previa in mid-pregnancy deliversearlier.

The tumor suppressor gene p53 and p16, both of which play an important role in inhibition of tumorigenesis, are homozygously deleted in human myeloid leukemia cell line K562. To explore the inhibition of K562 cell proliferation by wild type p16 and p53 genes, both p16 and p53 genes were co-transfected into K562 cells mediated by liposome. The expression of the two genes was measured by immunocytochemical method, the cell cycle was analysed by flow cytometry, and the number of recovered viable cells was assessed after transfection. After co-transfection, the p53 and p16 positive cells were 23% and 28%, respectively. The results showed that co-transfection of p16 and p53 genes significantly inhibits cell proliferation comparing with transfection either by p16 gene or by p53 gene (P < 0.05). Expression of p16 and p53 proteins increased the cell number in G(1) phase but decreased the cell number in S phase. It is concluded that co-transfection of p16 and p53 genes has a stronger growth-inhibitory effect on K562 cell growth than that of transfection only by p16 gene or by p53 gene, may be a pathway for gene therapy in leukemia.
