Objective To explore the treatment methods and clinical result with the flap combining peroneus longus muscle supplying with the nutrient vessels of sural nerve to repaire the chronic achilles tendon rupture with skin defect.Methods After anatomic investigating,Analyzing 6 cases.Excising peroneus lon- gus muscle combining with the foot external flap,supplying with the pediele of the nutrient vessels of sural nerve to repaire the chronic achilles tendon rupture with skin defect,among them,the size of flap was about 6.0 cm?5.5 cm～16.5 cm?11.0 cm,the defect length of achilles tendon 2.0～7.5 cm.Results All ca- ses observed 4 to 16 months,all eases skin and achilles tendon were survived completely,the flap skin appear- ence was good,none ulcer.1 cases part necrosis,1 eases rerupture,Both healed after changed dressings.Ac- cording to Arner-Lindholm criteria to test the efficacy the result were excellent in 3 patients,good in 2,poor in 1.Conclusion It is an ideal way using the flap combining peroneus logus muscle with the nutrient vessels of sural nerve repairing the chronic achilles tendon rupture with skin defect.The advantage is operting conven- iently,transferred adjaeently,repairing the skin and tendon defect simultaneously,healing fastly and anti-bac- teria strongly,biomeehanies property and function is similar to the heel,it can fit the heel and skin for repai- ring.

Objective To explore distally-based the interal ankle perforator saphenou neuro-veno-fasciocutaneous flap has been universally adopted for the repairment of the foot and the ankle soft-tissue defects.Methods Lay a foundation of anatomic studying,using the interal ankle perforator saphenous neuro-venofasciocutaneous flap 10 cases, the flap axis point was 1-3 cm above the pink of the interal ankle, average 2 cm. The scope of the flap were 4.0 cm× 3.0 cm-8.0 cm× 6.0 cm. Results All the perforator saphenous neuro-veno-fasciocutaneous flap were lively. About all, 2 cases had the small distant part necrosis, 1 case accompanying with subcutaneous tissue heels after change dressings, another heels after skin grating. All case can walk as usual, the flap had wear-resisting and keenly feel. Conclusion Distally-based the interal ankle perforator saphenous neuro-veno-fasciocutaneous flap, near ankle, donner area exiting fine, utlizing scope large, skin nice, grating easy, no hurting important blood vessle, alive rate high, it is an good donner area in repairing the foot and the ankle soft-tissue defects.

OBJECTIVEThe 85th percentile of waist circumference (WC) is considered an appropriate cutoff for Chinese children in the prediction of cardiovascular risks in previous researches, but the risk for hypertension of moderate WC maybe underestimated. The purpose of this study was to understand the characteristics of the WC curve trajectory of children with hypertension and to determine the appropriate cutoffs for waist circumference for Chinese school-age children and adolescents for predicting hypertension risk factors.

METHODSA total of 8194 Han children aged 7 - 17 years were selected from schools in Suzhou, Hefei, and Chizhou cities in Anhui province by stratified cluster sampling. WC and blood pressure were accurately measured in all subjects. LMS (lambda-mu-sigma) method was used to construct WC centile curves. Optimal WC cutoffs were determined by comparing the performance of different percentile sets of WC cutoffs in predicting hypertension risk factors.

RESULTSThe fitted LMS curves of WC for the group of boys with hypertension deviate in parallel from that for the corresponding curve in the entire boy study population with higher WC. The WC curves for the group of girls with hypertension gradually upward deviated from the corresponding curve before 12 years of age and then gradually returned to the corresponding curve. WC of boys at the percentiles of 60 was already associated with an increased risk of hypertension and hazard ratio of WC at percentiles of 60, 70, 80, and 90 increased from 1.88(95%CI: 1.18 - 2.99) to 4.87 (95%CI: 3.31 - 7.16). WC of girls at the percentiles of 70 was already associated with an increased risk of hypertension and hazard ratio of WC at percentiles of 70, 80, and 90 increased from 1.71 (95%CI: 1.07 - 2.73) to 3.32 (95%CI: 2.16 - 5.09).

CONCLUSIONSThe WC growth trajectory of children with hypertension varies with gender. WC is an independent predictor of childhood hypertension, even when it is well within what is now defined as the normal range of WC. Thus, it is helpful to prevent the risk of cardiovascular disease of children using the parameter that WC cut-off level lower than 85th percentile.

AIMTo study the synthesis and antibacterial activity of ciprofloxacin derivatives.

METHODSCiprofloxacin derivatives were synthesized primarily from 2-methyl-5-nitroimidazol and ciprofloxacin through nucleophilic substitution. The antibacterial activity of the synthesized compounds were tested.

RESULTSNine new compounds were synthesized. The structure of the title compounds were confirmed by 1H NMR, MS and element analysis.

CONCLUSIONCompounds II, IVC and IVD showed appreciable antibacterial activity, and were worth further studying.

AIMTo determine the protective effect of ONO-1078, a leukotriene receptor antagonist, on focal cerebral ischemia induced by endothelin-1 in rats.

METHODSSlow microinjection of endothelin-1 (120 pmol in 6 microL, for > 6 min) into the region near the middle cerebral artery was used to induce focal cerebral ischemia. ONO-1078 (0.1 mg.kg-1) was i.p. injected 1 h before endothelin-1 injection. Neurological symptoms, brain edema, brain infarction size, and the survival neurons in cortex and striatum were observed 24 h after ischemia.

RESULTSIntracerebral microinjection of endothelin-1 induced remarkable neurological symptoms, brain infarction, brain edema, and decrease of survival neurons in the cortex and striatum. In rats pretreated with ONO-1078, endothelin-1-induced brain edema and brain infarction size were decreased. The numbers of survival neurons in striatum and cortex were increased significantly. The neurological symptoms were improved but not significantly.

CONCLUSIONONO-1078 possesses neuroprotective effect against cerebral ischemic injury induced by endothelin-1, therefore, leukotrienes may play a role in the injury of cerebral ischemia.

OBJECTIVETo explore the relationship between genetic polymorphisms of CACNA1C that encoded the a1c subunit of the L-type calcium channel and the efficacy of calcium channel blocker (CCB, Nifedipine extended release tablet/20 mg/d) in essential hypertension (EH) patients of Han Chinese in Wenzhou.

METHODSFor the enrolled 103 EH patients, Multiplex Polymerase Chain Reaction (Multi-PCR) and matrix assisted laser desorption ionization time of flight MS (MLDI-TOF MS) were performed to detect their genotypes (rs216008, rs1051375, rs2299661, rs10848683, rs215976), blood pressure (BP) after CCB monotherapy was compared among patients with different genotypes.

RESULTS(1) Blood pressure was significantly reduced in all patients post CCB (P < 0.05 vs. pre-CCB). (2) Diastolic blood pressure reduction was more significant in subjects with rs2299661 C/C genotype (wild genotype) than in subjects with rs2299661C/G and rs2299661G/G genotype (mutational genotype) [(12.46 ± 7.91) mm Hg (1 mm Hg = 0.133 kPa) vs. (7.22 ± 8.01) mm Hg and (5.93 ± 9.77) mm Hg, P < 0.05]. (3) Systolic blood pressure reduction was more significant in subjects with rs216008 C/C genotype (wild genotype) than in subjects with rs216008 C/T genotype (mutational genotype) [(20.60 ± 12.35) mm Hg vs. (13.62 ± 10.21) mm Hg, P < 0.05]. (4) Blood pressure reduction was similar between subjects with genotype of rs1051375, rs10848683 and rs215976.

CONCLUSIONEH patients with wild genotype of rs2299661 and rs216008 in CACNA1C are more likely to be responders of CCB monotherapy.
