Objective To introduce the clinical apply of middle and small skin defect in finger injury with lateral arm free perforator flap.Methods (1) Ten cadavers were injected with a modified lead oxide-gelatin mixture.Later,CT scan,three-dimensional reconstruction of the cutaneous perforator vessels on the later arm.Then simulate the flap design.All cadavers were dissected before CT scanning.(2) Eighteen cases of middle and small skin defects in finger injury were treated with lateral arm free flap.The defect area were from 3 cm × 4 cm to 6 cm × 9 cm.Results Our research showed that the average caliber diameter of perforators of profunda brachial artery(PBA) was (0.71 ± 0.15) mm,and Posterior radial collateral artery(PRCA) was (0.94±0.22)mm.The results of pedicle length of perforator of PBA was (2.74 ±0.42) cm:(2.96 ±0.37) cm,and PRCA was (4.78 ±0.63) cm:(4.86 ±0.51) cm.3D reconstructive results showed that the perforators of PBA and PRCA dominated the lateral upper arm area.The flap of 18 cases survived after the operation.The wound of providing area was directly sutured or skin grafting and got healing.All cases were followed up for 6 months to 3 years,and the average follow-up time was 11 months.There was a little swelling on the outlooks of the flap,but the texture and sensation of the flap was good.Conclusion The lateral arm free perforator flap has a stable vessel pedicle,good texture and sensation,so it was a good method to repair middle and small skin defect in finger injury.

Tumor 2008;28(11):911-915
Objective: To study the expression of function-unknown PNMA5 gene in hepatocellular carcinoma (HCC) and its relationship with proliferation of HCC. Methods: PNMA5 was over-expressed in HCC analyzed by gene expression profiling. We investigated the expression of PNMA5 through RT-PCR and real-time fluorescent quantitative PCR (RFQ-PCR) in normal liver tissues, HCC, and adjacent non-cancerous liver tissues (non-HCC). PNMA5 gene was silenced in Focus and PLC liver cancer cells by using RNA interference technology. The changes in cell growth curve were quantitatively analyzed by performing CCK-8 experiment after silencing the endogenous PNMA5 gene expression. Results: PNMA5 was mainly expressed in testis, ovary, and brain tissues out of the 14 kinds of normal human tissues. PNMA5 mRNA was significantly up-regulated in 42% (5/12) HCC specimens, which was 2-fold higher than that in non-HCCs (P < 0.05). Interestingly, the growth of Focus and PLC cells was markedly inhibited after silencing PNMA5 gene expression (P < 0.01), and the number of tumor cells progressing through G1 and entering S phase was significantly decreased as compared with the control cells transfected with siRNA-NC (P < 0.01). Conclusion: PNMA5 plays an important role in maintaining the malignant phenotype of HCC. It may be a novel tumor-testis associated gene. Further investigation of its function may help to find the new mechanism for the HCC tumorigenesis. PNMA5 may become a new candidate target in HCC treatment.

OBJECTIVE:To explore the role of clinical pharmacists in the treatment of pan-drug resistant Acinetobacter bau-mannii infection. METHODS:Clinical pharmacists participated in the treatment for a severe pneumonia case of pan-drug resistant A. baumannii infection. Clinical pharmacists supplied overall pharmaceutical care and suggestions with respects to initial medication scheme evaluation,pathogen judgment,therapy drug selection,ADR disposal,etc.,including anti-infective treatment of moxifloxa-cin 0.4 g,ivgtt,qd+meropenem 0.5 g,ivgtt,q8 h+linezolid 0.6 g,ivgtt,q12 h;anti-pan-drug resistant A. baumannii infection of cefoperazone sodium and sulbactam sodium 3.0 g,ivgtt,q8 h+tigecycline 50 mg,ivgtt,q12 h;liver protection of ademetionine 1, 4-Butanedisulfonate 1.0 g,ivgtt,qd+reduced glutathione 1.8 g,ivgtt,qd. RESULTS:After 25 d treatment,the patient hadn’t been fe-vered,and hemogram and hepatic function index decreased to normal value. CONCLUSIONS:Clinical pharmacist should be en-gage in anti-infective treatment and pharmaceutical care,and provide physicians reasonable medication suggestion so as to promote care rate in the clinic.

OBJECTIVE:To systematically review the relationship of clinical efficacy between XPD Lys751Gln (A/C),XPD Asp312Asn(G/A)and platinum-based chemotherapy in patients with advanced non-small cell lung cancer(NSCLC),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed, Cochrane Library, EMBase, Medline, CJFD,VIP database and WanFang database,studies about the effects of XPD Lys751Gln and XPD Asp312Asn polymorphism on ef-fectiveness,clinical outcomes and adverse drug reaction of platinum-based chemotherapy in advanced NSCLC patients were collect-ed,and Meta-analysis was performed by using Rev Man 5.3 software. RESULTS:Totally 30 studies were included,involving 5 028 patients. Genetic testing showed that XPD Lys751Gln divided into mutant gene (Lys/Gln + Gln/ Gln) and wild-type gene (Lys/Lys),while XPD Asp312Asn divided into mutant gene (Asp/Asn + Asn/Asn) and wild-type gene (Asp/Asp). Results of Me-ta-analysis showed,the progression-free survival (PFS) of Lys/Gln+Gln/Gln patients with platinum in XPD Lys751Gln polymor-phism was obviously lower than Lys/Lys patients [OR=-1.12,95%CI(-1.73,-0.50),P<0.001],while there was no significant difference in the chemotherapy effectiveness and total survival period. The effective rate of Asp/Asn+Asn/Asn patients for platinum in XPD Asp312Asn polymorphism was lower than Asp/Asp patients [OR=0.80,95%CI(0.68,0.96),P=0.02],while there was no significant difference in the total survival period and PFS. Meanwhile,the incidence of Ⅲ-Ⅳ level gastrointestinal adverse reac-tions of Lys/Gln+Gln/Gln with platinum in XPD Lys751Gln polymorphism was higher than Lys/Lys patients [OR=0.43,95%CI (0.20,0.94),P=0.03],and there was no significant difference in Ⅲ-Ⅳ level blood system adverse reactions. CONCLUSIONS:XPD Lys751Gln polymorphism may be associated with PFS and Ⅲ-Ⅳ level gastrointestinal adverse reactions for advanced NSCLC patients with platinum-based chemotherapy,while XPD Asp312Asn polymorphism may have effect on platinum-based chemotherapy,both of them may be as estimate the chemotherapy effect and prognosis detection index of platinum-based chemo-therapy.

To study the chemical constituents from the root of Berchemia lineata (L.) DC., nine compounds were isolated from the EtOAc extract by using silica gel, RP-C18 silica gel column chromatography and preparative HPLC. Based on the spectroscopic analysis, their structures were identified as 5-hydroxy-7-(2'-hydroxypropyl)-2-methyl-chromone (1), (-)-(1'R, 2'S)-erythro-5-hydroxy-7-(1', 2'-dihydroxypropyl)-2-methyl-chromone (2), naringenin (3), eriodictyol (4), (+)-aromadendrin (5), (+)-taxifolin (6), (+)-catechin (7), (+)-epigallocatechin (8) and quercetin (9). Among them, compound 2 is a new chromone derivative. Compound 1 is a known chromone derivative and isolated from this genus for the first time. Compounds 3-9 are known flavonoids and isolated from this plant for the first time.

Objective Intestinal epithelial barrier damage is closely related to a variety of gastrointestinal disease,how to maintain its function effectively is the key to treat all these diseases.This research attempts to explore the protective effect and its mechanism of toll-like receptor 2 (Toll-like receptor,TLR2)on permeability of intestinal epithelial barrier by experiments in vitro,to lay a foundation for new treatment methods.Methods We cultured non-transfected Caco-2 cells,TLR2-deficiency Caco-2 cells,TLR2-overexpressed Caco-2 cells in normal control group until the 21 st d,then tested transepithelial electrical resistance(TEER) which reacts the permeability of epithelial barrier.We cultured 3 types of cells in inflammation group until the 19th d treated with 10 ng/ml IL-1 beta for 48 h,then tested TEER values at the 21st d.We treated 3 types of cells in inhibition group with PI3K/Akt pathway inhibitor for 1h befor IL-1 beta,then tested TEER values at the 21st d.Results TEER value of TLR2-deficiency Caco-2 cell monolayer significantly reduced (P < 0.01),whereas TEER value of TLR2-overexpressed Caco-2 monolayer raised,but without statistically significant.TLR2 can prevent IL-1 beta caused TEER decreasing (P < 0.01),but the effect disappeared after given PI3K/Akt pathway inhibitor.Conclusion TLR2 can regulate the permeability of intestinal epithelial barrier.In addition,TLR2 can protect permeability increasing caused by inflammation,this effect mediated by PI3 K/Akt pathway.
