Medical Journal of Chinese People's Liberation Army 1983;0(05):-
The authors reported the results of anatomicat study of the scapular region (ninety-four sides) and the use of the parascapular composite flap in the repair of skin defects of the hand and foot.The parascapular flap is supplied by the circumflex scapular vessels. For exposure of the vascular pedicle an incision is made 7cm below the mid-point of the scapular spine, extending from the posterior axillary fold to the mid-point of the spine. Muscles are retracted and the circumflex scapular vessels are seen winding over the axillary border of the teres minor. Then the incision is extended from both ends of the above incision toward the inferior angle of the scapula to form an elliptical incision. The flap is raised by subfascial dissection from the mid-point of the spine towards the axilla, and ended by dividing the pedicle at the base of the circumflex scapular vssels. Since October 1982, the authors have applied flaps of such kind to repairing massive skin delects in the hand and the foot in 7 patients with success.

Objective To investigate the value of radionuclide bone imaging in the diagnosis and localization of osteoporotic vertebral compressive fracture.Methods Percutaneous vertebroplasty was applied to 40 patients suffering from osteoporotic vertebral compressive fracture.Responsible vertebral bodys located according to the radionuclide bone imaging was involved as bone scan group,and responsible vertebral bodys located according to the physical examination,X-ray,CT and MRI as standard group.Then the Kappa test was carried out.Result In bone scan group,56 vertebrae were located by radionuclide bone imaging,and in standard group,58 vertebrae were located by X-ray,54 vertebrae by CT and 52 vertebrae by MRI.The Kappa value was 0.76,indicating essentially excellent agreement and statistical significance.Conclusion Radionuclide bone imaging was another good choice for the diagnosis of osteoporotic vertebral compressive fracture.Especially for cases with contraindication of MRI,it offers a reliable choice.

BACKGROUND:Percutaneous vertebroplasty is mainly used to treat senile osteoporotic compressive fractures,while for young patients,pedicle screw internal fixation is usually applied,but heavy trauma,nail broken,secondary surgery and other problems can be found occasionally.OBJECTIVE:To investigate the clinical efficacy of percutaneous vertebroplasty combined with granulated allogeneic bone grafting for thoracolumbar compressive fractures.METHODS:Twenty-one patients suffering thoracolumbar compressive fractures were recruited,and underwent percutaneous vertebroplasty combined with granulated allogeneic bone grafting.The Visual Analogue Scale scores,height ratio of fractured vertebrae and Cobb angle were detected before and after surgery.RESULTS AND CONCLUSION:(1) Compared with baseline,the Visual Analogue Scale scores were improved significantly at 1 day and 6 months postoperatively (P < 0.05).(2) The height ratio of fractured vertebrae at 1 day and 6 months postoperatively was significantly higher than that before treatment (P < 0.05).(3) The Cobb angle of fractured vertebrae at 1 day and 6 months postoperatively was significantly less than that before treatment (P < 0.05).(4) The mean operation time was (52±12.3) minutes,and the mean blood loss was (11.5±1.5) mL.(5) These results suggest that percutaneous vertebroplasty combined with granulated allogeneic bone grafting can effectively restore the anterior fractured vertebral height,eliminate the cavity in the fractured vertebrae,renew the completeness and stabilization of the fractured vertebrae,which keep the spinal range of motion;therefore,it is a minimal invasive method in the treatment of thoracolumbar fractures.

Objective To investigate the association between a missense mutation (T/G, Ser 1369 Ala) in exon 33 of sulfonylurea receptor 1(SUR1) gene in type 2 diabetes patients and the glucose-lowering effect of Gliclazide. Methods One hundred and four type 2 diabetes patients were selected and orally administered with Gliclazide for 56 days. Venous fasting plasma glucose levels (FPG), plasma glucose levels half an hour after taking 75 g glucose (OGH) and two hours (OGT) after taking Gliclazide were measured. Ser1369Ala polymorphism genotypes(TT, TG, GG) of SUR1 gene were determined by Taqman method. The glucose-lowering effect of Gliclazide was compared among different groups. If FPG was reduced more than 20%, we define it as effective. People whose blood sugar level was effectively reduced and not significantly reduced were compared to find whether their genotype groups were different.Results The change of FPG,OGH and OGT on day 1 and day 57 among TT,TG and GG genotype groups had no statistically significant difference. There was no statistically significant difference of the efficacy of Gliclazide in recessive model (TT+TG vs GG). The combination of TG and GG was more effective in reducing blood sugar level than TT. Conclusion Patients carrying one or two copies of the G allele were more sensitive to Gliclazide than patients carrying T allele.

Objective To evaluate the effects of two different short-term intensive therapies on ?-cell function in newly diagnosed type 2 diabetic patients.Methods Twenty newly diagnosed type 2 diabetic patients were divided into two groups of 10 patients each and randomly treated with glargine or glimepiride plus metformin for 4 weeks.The improvement of ?-cell function,FPG,PPG,HbA1c were measured before and after intensive therapy in each group.The difference in the improvement of ?-cell function,blood glucose and the frequency of hypoglycemia were compared between groups.Results After the treatment,FPG(12.25 vs.6.05 and 11.83 vs.6.35mmol/L),2hPG(18.67 vs.8.11 and 16.95 vs.8.73mmol/L),HbA1c(8.98% vs.7.38% and 9.17% vs.7.71%) were significantly decreased(all P

Objective To study an identified leucine-rich repeats(LRRs)protein,LRR containing 19(LRRC19),and to determine the distribution,localization,and biological function of LRRC19 mRNA expression in spleen cells.Methods Bioinformatics analysis was used to predetermine the structure of LRRC19 gene and protein.The distribution and localization of LRRC19 mRNA expression were detected by hybridization in situ with LRRC19 mRNA specific probes and reverse transcriptase polymerase chain reaction(RT-PCR).Additionally,the activity of secreted alkaline phosphatase(SEAP)was detected for analyzing the nuclear factor-kappa B(NF-?B)activation in HEK293T cells transfected with the expression vector of LRRC19 in vitro.Results LRRC19 was found to be a transmembrane protein,with 4 LRR motifs,a single transmembrane domain and two phosphorylation sites of casein kinase 2(CK2)at cytoplasmic domain,as analyzed through bioinformatics soft wares.Previous study revealed that LRRC19 without cytoplasmic Toll/IL-1 receptor(TIR)domain could activate NF-?B to enhance the expression of proinflammatory cytokines.LRRC 19 could also be demonstrated by ectopic expression in RAW264.7 cells after transfection with murine LRRC19 expression plasmid pcDNA3.1-V5-LRRC19 indicating that it was a transmembrane protein.In persent study,the results of hybridization in situ and RT-PCR showed that LRRC19 mRNA was expressed in the germinal center and splenic cord of mouse spleen.Additionally,LRRC19 was predominantly expressed in CD5+ lymphocyte,known as B1 cell.In vitro study also indicated that several pathogens might significantly enhance the NF-?B activity of the cells transfected with LRRC19.Conclusion LRRC19 might be a transmembrane receptor,and it may be able to recognize the conserved sequence of pathogens,participate in the induction of cell signaling,activate the NF-?B signal pathway,promote transcription of target genes,and modulate the innate immune response.

Experiments were carried out in 31 urethane anesthetized, Suxamethonium chloride paralyzed and artificially ventilated rats. The results were as follows: microinjection of γ-amino butyric acid (GABA) into parabrachial nuclei (NPB) markedly decreased the mean arterial pressure (MAP) (P<0. 001), while the microinjection of bicuculine (Bic) into NPB caused a significant increase in MAP (P<0. 001). The depressor effect of GABA could be blocked by preinjection of Bic in NPB. The above agents microinjected into NPB had no significant effect on heart rate (P>0. 05). The results indicated that: (1) GABA in NPB exerts tonic depressor effect; (2) Endogenous GABA in NPB exerts tonic depressor action and takes part in maintenance of normal blood pressure level.
