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.

OBJECTIVE: To summarize the characteristics and investigate the mechanisms of boat propeller injuries so as to explore the identification methods between boat propeller injuries and corpse dismemberment. METHODS: More than 100 autopsy cases of boat propeller injuries were collected in a period between 1994 and 2005 in Huzhou district, Zhejiang province. The characteristics of injuries caused by propeller, including abrasion, wound, fracture and severed wound, and the characteristics of clothing, were retrospectively studied and summarized. The severed cross wound section of boat propeller injuries was compared with that caused by corpse dismemberment. RESULTS: The boat propeller injuries were resulted from high-speed propellers with enormous splitting power and mechanical cutting, while corpse dismemberment were resulted from cutting and dismembering the body with sharp instruments. Due to the different mechanisms, the different strength of force and recoil force, the severed wound cross section had different characteristics. CONCLUSION Wounds caused by boat propeller injuries have their unique characteristics, distinguished from wounds of dismembered corpse.

Objective To investigate the reasons of blood pressure not reached standard in community outpatients with hypertension.Methods During January 2001 to December 2006,2798 patients fitting the China hypertension guide standard providing prevention and curing were involved in this study.From them,1574 cases were treated repeatedly,and the blood pressure did not continuously reach the controlled standard.The reasons were analyzed by regular visiting and correspondence with patients.Results The reasons of blood pressure not reached controlled standard related with chiefly the following factors:patient had bad compliance,and not positively intervened the way of life,and not took medicine according to the doctor's advice;doctors were not familiar with the methods of preventing hypertension and the treatment was nonstandrad.Conclusion The reasons of blood pressure not reaching standard in community outpatients with hypertension mainly are that the patients have poor knowledge about hypertension and compliance,and the treatment is nonstandrad.

Objective To determine the impact of uric acid changes on kidney function in middle-aged and elderly women with normal renal function.Methods Serum uric acid and estimated glomerular filtration rate(eGFR) were studied by prospective cohort analysis in 1152 middle-aged and elderly Dalian women with serum uric acid<7 mg/dl, estimated glomerular filtration rate(eGFR)≥90 ml·min-1·(1.73 m2)-1, and age>45 years old.Results The analysis of variance (ANOVA) of clinical indices between baseline and follow-up data showed that an eGFR was decreased after three years in both middle-aged and elderly women even with normal serum uric acid.Compared with those in the lowest guartile subgroup, a significant drop of eGFR to less than 90 ml·min-1·(1.73 m2)-1 was seen in those with the highest guartile of baseline serum uric acid group (OR=1.707, 95%CI 1.192-2.443, P=0.003).Furthermore, there were positive correlations between changes in the levels of serum uric acid and eGFR, and linear regression analysis showed that, as the change level of serum uric acid increased, the change level of eGFR declined(β=1.562, 95%CI 1.050-2.075, P<0.01], and the changing degree of uric acid increase is independent risk factors refor eGFR reductions.Conclusion Reduction in eGFR level is inversely related to serum uric acid in perimenopausal and postmenopausal women.However, our study showed that, women with serum uric acid level ranging from normal, slight increase, and relatively high levels, the increasing degrees of uric acid are independent risk factors responsible for the changing degree of eGFR reduction.

OBJECTIVE: To explore the relationship between the expression of EIIIA+ fibronectin in incised wound of rat's skin and injury time. METHODS: The wounding model was established by cutting the dorsal skin of 48 adult SD rats. The rats were sacrificed at the pre-set injury time as immediately, 0.5 h, 1 h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin samples were taken at the margin of wound. The expression of the EIIIA? fibronectin was detected by immunohistochemistry and Western blotting and the relationship be- tween its expression and injury time was observed. Results The expression of EIIIA+ fibronectin was not observed immediately. The basal cell of skin began to show positive expression 0.5 h after injury. With the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the Western blotting analysis. CONCLUSION The expression of EIIIA+ fibronectin could be used for estimation of injury time in the early stage of skin injury.

OBJECTIVETo establish a capillary electrophoresis-mass spectrometry(CE-MS) method for the analysis of nineteen organonitrogen pesticides in Paeoniae Radix Alba.

METHODSCE-MS analysis was performed on a 70 cm X 50 μm fused-silica capillary. The optimal buffer was composed of 1 % formic acid and 15 % methanol(V/V, pH 2.2). The temperature of capillary was controlled at 25 degree. The separation voltage was +20 kV. The optimal MS parameters were as follows: ESI-MS analysis was performed in the positive mode; 90 % methanol containing 0.2 % formic acid with a flow rate of 8 μl·min(-1) was selected as the sheath liquid; the flow rate and temperature of drying gas were 6 L·min(-1) and 250 degree, respectively; The nebulizing gas pressure was set at 5 psig; The optimal values of fragmentor and ESI voltage were 100 V and 5 000 V, respectively.

RESULTSThe nineteen pesticides had good linearity over the testing ranges. The average recoveries were in the range of 80.1 %-108.4 % with RSDs less than 20 % (except ethoxyquin and spiroxamine, those of which were 29.2 % and 22.3 % at 0.01 mg.kg(-1) concentration level). The LODs of nineteen pesticides were 0.503 ≊10.1 μg.kg(-1).

CONCLUSIONThe method can be used effectively to analyze the nineteen organonitrogen pesticides residue in Paeoniae Radix Alba.
