OBJECTIVE:To observe the clinical effects of Sanqi shengji ointment (SQSJO) preventing skin flap necrosis. METHODS:75 cases of local flap transfer in head and facial operation were randomly divided into blank group,treatment group, control group and with 25 cases in each group. After surgery,except for conventional treatment,treatment group was coated with SQSJO additionally;control group was additionally treated with rh-bFGF. The dressing was changed with iodophor in blank group conventionally till the wound healed. The skin flap necrosis,healing course,local skin temperature,swelling disappearance time and wound healing time were observed and compared among 3 groups after surgery. RESULTS:Compared with blank group,the incidence of skin flap necrosis decreased significantly in other 2 groups,there was statistical significance(P<0.05). There was sta-tistically significant difference in healing rate ameng 3 grups(P<0.05);there was no statistical significance in local skin tempera-ture among 3 groups after surgery (P>0.05);the flap swelling disappearance time and wound healing time of treatment group were significantly shorter than those of control group and blank group;there was statistical significance (P<0.05). CONCLU-SIONS:SQSJO can prevent skin flap necrosis accurately after flap transfer,and has no significant difference from rh-bFGF in pre-vention effect. Moreover,it is better than rh-bFGF in improving local swelling and shortening wound healing.

Objective To study the clinical significance of a novel marker of platelet clumps count provided by hematology analyzer in differentiating true thrombocytopenia from EDTA-dependent pseudothrombocytopenia (EDTA-PTCP). Methods Samples from 65 cases of thrombocytopenia (including 15 EDTA-PCTP samples and 50 random samples of true thrombocytopenia) and 50 healthy controls were analyzed using hematology analyzers, and samples with low platelet counts were checked by replacing citric acid and using manual microscope observation to identify true thrombocytopenia from EDTA-PTCP. A novel marker of platelet clumps count was used to differentiate the two diseases for samples anficoagulated with EDTA or citric acid. Results In 65 patients with thrombocytopenia, platelet counts were (48±11)×109/L detected by automatic hematology analyzers. Fifty of 65 cases were true thrombocytopenia which showed low platelet counts [(48±10)×109/L by automated analyzer and (46±11)×109/L by manual assay]. No significance was observed between them (t=-1.26, P0.05). Platelet clumps counts were 86±15. No platelet clamps were detected under microscope. The other 15 cases were EDTA-PTCP [platelet counts were (48±12)×109/L and platelet clumps counts (840±184) were increased significantly by automated analyzer and using EDTA anticoagulant] which showed obviously platelet clumps and no less platelet counts under microscope. After replacing citric acid, platelet counts [(141±13)×109/L by automated analyzer and (134±17)×109/L by manual microscope assay] were increased significantly. No significance was observed between them (t=-1.29, P0.05). Platelet clumps counts (75±12) were decreased obviously compared with EDTA anticoagulant method (t=-6.82, P<0.001). No platelet clumps were detected under microscope. Conclusion Platelet clumps counts may be a useful clinical indicator for monitoring of platelet aggregates, especially for EDTA-PTCP caused by platelet clumping.

OBJECTIVE:To compare the difference of the information about smoking affecting pharmacodynamics and pharma-cokinetics in prescription drug instructions between US and China. METHODS:The US and Chinese guidance for drug R&D and drug instructions editing,prescription drug instructions were collected;the information about smoking affecting pharmacodynamics and pharmacokinetics were retrieved from FDA drug instruction official website DailyMed and Yaozhi Network in China up to Jun. 19th,2014. The difference in related regulations and drug instruction were compared between US and China. RESULTS & CON-CLUSIONS:The guidance issued by US and China require that great importance should be attached to the effects of smoking on pharmacodynamics and pharmacokinetics,and it must be noted in drug instructions. Of 62 857 drugs recorded,smoking affected pharmacodynamics and pharmcokinetics of 34 drugs in US drug instructions,among which 9 drugs needed dose modifications;for above drugs,Chinese drug instructions pointed out great importance should be attached to the effect of smoking on pharmacodynam-ics and pharmacokinetics of 6 drugs,and only one drug(erlotinid hydrochloride)needed to be modified. The label rate of smoking affecting pharmacodynamics and pharmacokinetics was relatively low in Chinese drug instructions compared to US. It is suggested that the regulatory agent should standardize and improve related description in drug instruction,correct unsuitable content,revise the items which may result in severe consequence,and set up official website which can provide all drug instructions as soon as possible. Drug manufacturers should standardize clinical study of drugs before marketing,focus on the scientificity,completeness and normalization of drug instructions.

Objective To observe the level change of serum SOD in patients with severe acute respiratory syndrome (SARS). Methods The levels of serum SOD in 66 patients with SARS were measured by RIA, and compared with controls. Results The levels of serum SOD in patients with SARS were significantly lower than those in controls, and in severe type of SARS patients were lower than those in the other types. The levels of serum SOD in the recovery stage of SARS patients increased, but still was lower than those in controls. Conclusion Excessive free radicals were produced in patients with SARS, and SOD was depleted. The level change of SOD in patients with SARS may reflect state of disease. Dynamic detection of serum SOD level is helpful for monitoring state of SARS. It may be an important therapeutic measure that excessive free radicals were eliminated from SARS patient body.

Objective To investigate the sensitivity of the real-time fluorescence PCR technique and the bacterial culture for detecting the colonization of group B Streptococcus(GBS)in late pregnant women.Methods 2 specimens were collected from preg-nant women genital tract-rectal secretions swabs,one specimen for conducting the bacterial culture and another for conducting the real-time PCR technique to detect genital GBS.The accuracy and rapidness were compared between the two methods.308 cases of pregnant women were divided into the GBS positive group and the GBS negative group according to the detection results of the real time real-time fluorescence PCR technique.The relation between the occurrence of premature rupture of membranes with GBS was investigated by the comparative analysis.Results Among 308 pregnant women with GBS detection,18 cases were positive by the ordinary bacterial culture with the positive rate of 5.8%(18/308),while 28 cases were positive by the real-time fluorescent PCR with the positive rate of 9.4%(29/308).In the GBS positive group detected by PCR,the premature rupture of membranes occurred in 9 cases with the positive rate of 31%,while in the GBS negative group detected by PCR,which occurred in 33 cases with the pos-itive rate of 11.83%.Conclusion This survey shows that the positive detection rate of the real-time fluorescent PCR technique is significantly higher than that of the bacterial culture method,the application of this detection technique for detecting GBS provides the basis for rapidly diagnosing GBS and conducting the prophylactic use of antibacterial drugs more accurately and more effectively.

BACKGROUND: Chinese herb tuber fleeceflower root can enhance learning and memory ability and anti-cerebral ischemia ability in rats,while 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside,the main effective component of tuber fleeceflower root,has very strong brain-protecting ef fects such as anti-oxidation and anti-aging.OBJECTIVE: To observe the amelioration of learning and memory dis order after administration of 2,3,5,4'-tetrahydroxystilbene-2-O-3-D-glucoside in mice with learning and memory disorder caused by scopolamine.DESIGN: Randomized controlled trial.SETTING: Institute of Pharmacology, Xuanwu Hospital of Capital University of Medical Sciences.MATERIALS: The experiment was conducted in the Institute of Pharmacology,Xuanwu Hospital of Capital University of Medical Sciences,be tween February 2000 and May 2000.Totally 50 male Kunming mice were recruited and randomized into 5 groups: normal control group, model group,positive control group, 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside 0.03 g/kg group (low-dose group), and 2,3,5,4 '-tetrahydroxystilbene-2-O-β- D-glucoside 0.1 g/kg group(high-dose group).2,3,5,4'-tetrahydroxystil bene-2-O-β-D-glucoside was an effective component extracted from Chinese herb tuber fleeceflower root in the Department of Pharmacology, Xuanwu Hospital of Capital University of Medical Sciences.Piracetam was the positive control drug.Morris water maze and passive avoidance reflex box were made in the Institute of Materia Medica, the Chinese Academy of Medical Sciences.METHODS:Administration was given 5 days before experiment.Tap water was intragastrically grven into the mice in normal group and model group. Piracetam of 0.7 g/(kg.d) was given to the mice in positive control group and 0.03 g/kg of 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside was given to small-dose group and 0.1 g/kg to large-dose group for 5 consecutive days.Model establishment started 30 minutes after adminis tration in each group on day 6. The same volume of normal saline was in traperitoneally injected into the mice in normal control group and 1 mg/kg of scopolamine was intraperitoneally injected into mice in the other groups.Morris water maze and passive avoidance tests were carried out 20 minters later.Injection dose of model establishment of Morris water maze was 1 mg/kg and that of passive avoidance test was 10 mg/kg.MAIN OUTCOME MEASURES:① Searching distance and time of mice in Morris water maze in each group.② Latency and entry-times of mice in passive avoidance test in each group.RESULTS:All the 50 mice were recruited in the experiment,and 49 of them entered the result analysis,1 mouse in model group died because of intraperitoneal hemorrhage when scopolamine was injected.① Results of Morris water maze test: Searching time and distance were significantly shortened in large-dose group as compared to those in model group[(77.814± 46.492), (99.319± 38.104)s; (1 370.914± 917.40), (1 808.77± 869.36)cm; P all ＜ 0.05]. ② Results of passive avoidance test: The number of en try times in small-dose group and large-dose group was significantly de creased compared with that in model group [(0.00± 0.00), (0.00± 0.00),(0.8571± 2.267) times, P ＜ 0.01], and the latency had an extended tenden cy [(300± 0.00), (300± 0.00), (269.71± 80.128) s ].CONCLUSION: 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside given to mice with learning and memory disorder induced by scopolamine can shorten the searching time and distance in Morris water maze and reduce the number of mistake-making times in passive avoidance test. It suggests that it has ameliorative effects on learning and memory disorder.
