Objective To investigate effect of double end-to-side neuroanastomosis for bilateral obsolete proper digital nerve injuries.Methods From November 2000 to October 2009,40 patients with bilateral obsolete proper digital nerve injuries were admitted to our center.Fifteen patients underwent double end-to-side neuroanastomosis.During operation,the injured digital nerve was excised,then bilateral distal ends and proximal ends were sutured,respectively; consequently,the distal and proximal nerve bows were formed.A cutaneous antebrachii lateralis nerve was freed and obtained from the homolateral forearm,then divided equally to 2 parts which were used to bridge the 2 nerve bows.Thirteen patients underwent single end-to-side neuroanastomosis,while other 12 patients underwent end-to-end neuroanastomosis.Results Thirty one patients were successfully followed up for 6 to 8 months.In double end-to-side neuroanastomosis group,12 patients were successfully followed up; anaesthesia and pain of the injured fingers disappeared completely; finger pulp was plump with good flexibility; the average result of sensation measurement was S(4.21 ±1.97),which was significantly higher than those of the other 2 groups; the average result of two point discrimination was 5.4±0.9 mm which was significantly lower than those of the other 2 groups.In single end-to-side neuroanastomosis group,10 patients were successfully followed up; anaesthesia relieved and spontaneous pain disappeared completely,but there was still tenderness; the average result of sensation measurement was S(1.57±0.72); the average result of two point discrimination was 7.2±1.2 mm.In end-to-end neuroanastomosis group,9 patients were successfully followed up; anaesthesia and pain relieved; the average result of sensation measurement was S(3.19± 1.04); the average result of two point discrimination was 7.68±0.8 mm; there were significant differences in results of sensation measurement and two point discrimination between the latter two groups.Conclusion The double end-to-side neuroanastomosis is a valuable method for repairing bilateral obsolete proper digital nerve injuries.

Objective To clone and express the extracellular portion of mouse Fcγreceptor Ⅱ-b ( FcγRⅡb) and to analyze the functions of the expressed proteins in a mouse model of systemic lupus ery-thematosus ( SLE) .Methods The gene fragment encoding FcγRⅡb was amplified by PCR, and then in-serted into the prokaryotic expression vector pET-32a(+) to construct the recombinant expression plasmid pET-FcγRⅡb.The expression plasmid was identified with restriction enzymes and then sent to the Shanghai Bio-Engineering Co.LTD for further sequencing analysis.The transformed Escherichia coli ( E.coli) BL21 ( DE3) strains carrying the recombinant expression plasmid pET-FcγRⅡb were induced by isopropylβ-D-1-thiogalactoside ( IPTG) .The expressed fusion proteins were analyzed by Western blot assay and purified with purification kits.The immune complex ( IC)-binding ability of FcγRⅡb was measured by ELISA.MRL/lpr mice with SLE in both the prevention (12 weeks old, n=40) and the treatment groups (19 weeks old, n=40) were randomly divided into four groups including 60 μl (4.8 μg) treatment group, 120 μl (9.6 μg) treatment group, 180μl (14.4μg) treatment group and PBS treatment group with 10 mouse in each group. The MRL/lpr mice with SLE were injected with the fusion protein through tail vein once a week for four con-secutive weeks.Serum samples were collected from each mouse after one week of observation.The levels of FcγRⅡb in soluble form in mice form both the prevention and treatment groups as well as the levels of anti-double stranded DNA antibodies were detected by ELISA.Results The gene encoding FcγRⅡb was ampli-fied and the recombinant expression plasmid pET-FcγRⅡb was successfully constructed.The recombinant proteins were expressed in the prokaryotic expression system, and then successfully purified.The recombi-nant proteins could bind to IC.Compared with the corresponding PBS control group, the levels of FcγRⅡb in soluble form were increased in mice from both prevention and treatment groups after treating with various concentrations of the recombinant protein (P<0.05).Significant differences in the levels of FcγRⅡb were found among mice of the same age after treating with different concentrations of the recombinant protein ( P<0.05).Compared with the corresponding PBS control group, the levels of anti-double stranded DNA anti-bodies were decreased in mice from both prevention and treatment groups after treating with various concen-trations of the recombinant protein (P<0.05).The levels of anti-double stranded DNA antibodies were grad-ually decreased along with the increasing dosage of protein (P<0.05).Conclusion The extracellular por-tion of murine FcγRⅡb in soluble form was successfully expressed.The recombinant proteins played a cer-tain role in the prevention and treatment of SLE in a mouse model.

Objective:To analyze the therapeutic effect and safety of finasteride on aged patients with isolated systolic hypertension (ISH)complicated benign prostatic hyperplasia (BPH).Methods:A total of 84 aged ISH + BPH pa-tients admitted from Jun 2011 to May 2013 were selected.According to medication plan,they were divided into fin-asteride group (n=44)and routine treatment group (n=40,only received routine treatment because they cannot use finasteride).Course of treatment was all six months.International prostate symptom score (IPSS),quality of life (QOL) questionnaire score,prostate-specific antigen (PSA),incidence rate of acute urinary retention,maximum u-rinary flow rate (Qmax),postvoid residual urine (PRV),prostate volume (PV)and incidence rate of adverse reac-tions were compared between two groups.Results:Compared with routine treatment group,there were significant reductions in IPSS [(13.2±2.4)scores vs.(9.4±1.1)scores],PRV [(21.4±4.6)ml vs.(9.0±2.3)ml],PV [(36.8±3.8)ml vs.(29.5±3.0)ml],PSA [(2.45±0.74)μg/L vs.(1.26±0.48)μg/L]and incidence rate of acute urinary retention (17.50% vs.9.09%),P<0.05 or <0.01,and significant increase in Qmax [(10.2±2.4) ml vs.(13.7±3.8)ml]and QOL score [(3.1±1.0)scores vs.(4.7±1.5)scores]in finasteride group (P<0.05). There were no significant difference in incidence rates of adverse reactions between two groups,P>0.05 all.Con-clusion:Therapeutic effect of finasteride is significant and adverse reactions don’ t increase significantly in aged pa-tients with isolated systolic hypertension complicated benign prostatic hyperplasia.

Objective To compare the impact of conventional vs. zero-balanced ultrafiltration on serum pro-inflammatory factors,acute kidney injury and clinical prognosis after cardio-pulmonary bypass procedure. Methods Forty patients receiving cardiac surgery under cardio-pulmonary bypass procedures in Xiangyang Central Hospital during January 2013 to June 2013 were randomly divided into conventional ultrafiltration group(group A,n=20)and zero-balanced ultrafiltration group(group B,n=20). Blood and urine samples were collected on different time points( pre-operation,T0;pre-ultrafiltration,T1;immediately after ultrafiltration,T2;24 hours post-operation,T3;48 hours post-operation,T4;7 days post-operation, T5). TNF-α,IL-6,KIM-1,CysC,serum creatinine and urea nitrogen were detected and compared. Pre-and post-operative clinical data were also collected. Results There was no difference in baseline data or intra-operative data(p>0. 05). TNF-αand IL-6 started to increase when the operation began. Compared with conventional ultrafiltration,zero-balanced ultrafiltration alleviated the increase of TNF-α and IL-6,espe-cially on T2,T3,and T4(p<0. 05). Zero-balanced ultrafiltration also decreased CysC,Rbp,serum creati-nine and urea nitrogen on T2,T3,and T4 compared with conventional ultrafiltration(p<0. 05). A total of 11 patients experienced AKI( >grade I)in group A and 2 patients experienced in group B(p<0. 01). There were significant differences of ventilation time,total complication incidence and ICU stay time be-tween two groups. There was no difference in other complications,post-operative days in hospital or death rate within 30 days. Conclusion Though there is a trend of more patients receving renal replacement therapy,no statistical difference has been achieved. In conclusion,zero-balanced ultrafiltration can effec-tively decrease the concentration of serum pro-inflammatory factors,alleviate acute kidney injury and improve the clinical prognosis after cardio-pulmonary bypass procedures. It is a safe and reliable method valuable for promotion.
