Since 1970, 13 cases of reconstruction thumb and finger utilizing the second toe were performed. 13 out of 14 reconstructed digits survied with no complication. All wounds healed by primary intention. Emergency reconstruction has the following merits: it is completed in one stage, hence less suffering and economic loss to the patients;it promises early rehabilitation, early return to work and better functional results, as compared with delayed operation. Traumatic amputation of the thumb at or near the metacarpo-phalangeal joint with the transected part so badly injured that replantation is no longer fet-sible, and severe crushing injury of the thumb or all fingers are indicated for emergency reconstruction. Patient's age, occupation, desire for operation and general health should be considered individually before operation. The method of dissecting the second toe with the preservation of vasculization pattern of dorsalis pedis artery-first plantar metatarsal artery should be adopted in case the anatomic pattern of dorsal metatarsal artery belongs to Gilbert type Ⅲ.

Objective To discuss the role of activation of nuclear factor ?appa B(NF-?B) in apoptosis of alveolar macrophages(AM) induced by gadolinium chloride(GdCl3) in acute necrotizing pancreatitis(ANP).Methods Thirty sixty adult SD rats were randomized into three groups: normal control group,ANP group and the group treated by GdCl3.ANP was induced by intraductal administration of 5% sodium taurocholate,while the normal control rats received an infusion of normal saline.In GdCl3 treatment group,GdCl3 was injected into dorsal vein of penis right after ANP model was established.AM were harvested by bronchoalveolar lavage six hours after model was established.The generation of TNF-? and IL-1? in bronchoalveolar lavage fluid(BALF),and the level of myeloperoxidase in lung tissue were evaluated.The expression of NF-?B protein in AM was determined by western blot.The apoptosis of AM was detected by agarose gel electrophoresis and flow cytometer.The histological examination of lung tissue was checked.Results The levels of TNF-? and IL-1? in ANP group were significantly higher than the control group and GdCl3 treatment group(P

Abstract?AIM:To evaluate the efficacy of photocoagulation alone or combined with intravitreal Bevacizumab for radiation retinopathy ( RR) .?METHODS: There were 43 patients ( 43 eyes ) with RR were collected at the Fifth Affiliated Hospital Sun Yet-Sen University between Jan.2009 and Jan.2014.Twenty-one patients received the photocoagulation treatment combined with intravitreal bevacizumab and 22 patients received the treatment of photocoagulation alone.All the patients would complete ophthalmologic examinations, including best -corrected visual acuity ( BCVA ) , intraocular pressure, optical coherence tomography, fundus fluorescein angiography before and after the treatment.?RESULTS:BCVA:In monotherapy group, there were no statistically difference about BCVA before and after treatment ( P>0.05).In combined therapy group, the BCVA had been increasing gradually in 2wk, 1, 3, 6mo after treatment ( P <0.05 ). There was no significant difference about BCVA before and 1a after treatment ( P>0.05).In the comparison of BCVA in these two groups in 2wk, 1, 3, 6mo after treatment, the combined therapy group were better than monotherapy group in each time point (P<0.05), but no statistically significant difference was observed in these two groups at 1a after treatment (P>0.05).Central macular thickness (CMT):in monotherapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P <0.05 ). There was no significant difference about CMT before and after 1a treatment ( P>0.05).In combined therapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P<0.05 ). There was no significant difference about CMT before and 1a after treatment ( P>0.05).In the comparison of CMT between these two groups in the 2wk, 1, 3, 6mo after treatment, those of combined therapy group were thinner and difference were statistically significant ( P <0.05 ), but no statistically significant difference was observed in two groups at 1a after treatment (P>0.05).? CONCLUSION: Photocoagulation combined with intravitreal bevacizumab for the treatment of radiation retinopathy both have an effect on reducing the macular edema in a short time (6mo).But the long-term efficacy is poor.

Objective:To analyze the expression of LETM2 in KYSE150 and ECA109 cell lines and its effect on the proliferation, migra-tion, and invasion of esophageal squamous cell carcinoma (ESCC). Methods:The expression level of the LETM2 protein in 90 paired hu-man ESCC tissues and matched adjacent normal tissues was determined through immunohistochemistry. The expression level of LETM2 in ESCC cell lines was detected by real-time PCR and Western blot. The expression levels of LETM2 in KYSE150 and ECA109 cell lines were knocked down using lentivirus. MTT assays were performed to examine the effect of LETM2 on the proliferation of ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle. The effect of LETM2 depletion on the migration and invasion of ESCC cells was determined by Transwell assay. Results:LETM2 expres-sion was frequently upregulated in the ESCC tissues than in the adjacent normal tissues. The suppressed exogenous expression of LETM2 led to the inhibition of cell proliferation and colony formation. However, cell migration and invasion were not affected. The re-sults on the cell cycle distribution revealed that LETM2 knockdown acts as a negative regulator of the cell cycle at the G1 to S phase transition. Conclusion:LETM2 acts as a tumor-driven gene in the development and progression of ESCC. This finding suggests that LETM2 can be used as an efficient prognosis biomarker and a potential therapeutic target for ESCC.

Objective To investigate the effects of high-fat diet induced insulin resistance on fibroblast growth factor-21 (FGF-21) and its receptors expression in ApoE~(-/-) mice. Method Male ApoE~(-/-) mice were randomly divided into normal-chow group(NF,n=20)and high-fat fed group(HF,n=20) and fed for 16 weeks. The insulin sensitivity and glucose-lipid metabolism in awake mice were evaluated by hyperinsulinemic-euglycemic clamp technique combined with 3-[~3H]-glucose as a tracer. The Mrna expressions of FGF-21,β-klotho, and FGFR1-4 were measured by quantitative real-time PCR. FGF-21 protein levels were determined by Western blot. Results Fasting blood glucose, plasma insulin and free fatty acids, triglycerides, free fatty acids, and cholesterols were significantly elevated in HF group compared with NF group(all P<0.01). During the steady-state of clamp, plasma insulin was significantly higher in HF group than that in NF group(P<0.01), and glucose infusion rate was also significantly decreased(P<0.01). At the end of insulin clamp, glucose disappearance rate was significantly lower in HF group than that in NF groups(P<0.01). Hepatic glucose production in NF group was suppressed by 70% ,while in HF group it was suppressed by 51%. The FGF-21 Mrna expressions of hepatic and adipose tissues in HF group were significantly increased compared with NF group(both P<0.01), and β-klotho Mrna expressions increased(P<0. 05). In hepatic and adipose tissues, FGFRI, Mrna expressions were higher in HF group than those in NF group(both P<0.01) ,and FGFR3 Mrna increased(P<0.01 and P<0.05, respectively). In hepatic tissue,FGFR4 Mrna levels were significantly up-regulated in HF group(P<0. 05). Plasma FGF-21 levels were elevated in HF group compared with NF group(P<0.01) ,and FGF-21 protein expressions of hepatic and adipose tissues were also increased(both P<0.05). Conclusion FGF-21, β-klotho, FGFR1, and FGFR3 were significantly up-regulated in ApoE~(-/-) mice fed by high-fat diet, and they might be the targets in regulating glucose-lipid metabolism by FGF-21.
