Objective To evaluate the causes,clinical manifestations and diagnosis of tarsal tunnel syndrome. Methods Operation was performed for 18 patients ( 21 sides) with tarsal tunnel syndrome. Preoperative Takakura index was 3-7 points with an average of 6.4 points. Ganglion was found in 15 cases (17 sides), varicosity in 2 cases (3 sides) and lipoma in 1 case. Results The symptoms disappeared without recurrence in 0.5 to 17 years' follow-up (average 7.3). Postoperative Takakura index was 9-10 points (average 9.7). Conclusion Tarsal tunnel syndrome is rare in the clinical practice with varied causes and different clinical manifestations. Operation can be performed with satisfactory results for the patients unsuitable for conservative treatment.

Background Diabetes mellitus (DM) can provoke the apoptosis of retinal cells and downregulate the expression of calcitonin gene related peptide (CGRP) in the retina.Capsaicin promotes the release of CGRP and elicits protective effects on human organs.However,whether CGRP protects retinal cells in diabetic retinopathy (DR) is still unclear.Objective The study was designed to examine the effect of capsaicin on the apoptosis of retinal cells in diabetic rats and its relationship with CGRP.Methods Forty clean healthy adult male Sprague-Dawey rats were randomly divided into the diabetes group,capsaicin pretreated group,streptozocin (STZ)control group,capsaicin control group and plain control group,with 8 rats per group.The diabetic model was established by the intraperitoneal injection of 60 mg/kg in all rats except those of the plain control group.0.4 mL of a 1％ capsaicin injected at 20 mg/kg was subcutaneously injected for 3 consecutive days prior to model establishment in the capsaicin pretreated group,after which 1.2 mL of STZ was intraperitoneally injected on the fourth day.Rats from the STZ control group were administered intraperitoneally 1.2 mL of 0.1 mol/L,pH 4.5,citrate buffer.The capsaicin control group received subcutaneous injections of 0.4 mL of 1％ capsaicin at 20 mg/kg for 3 consecutive days,after which 1.2 mL of 0.1 mol/L,pH 4.5,citrate buffer was administered intraperitoneally.The rats were sacrificed at the tenth week after model establishment and retinal specimens were prepared for the apoptosis assay by TUNEL staining and the quantitative analysis of caspase-3 activity.Expression of CGRP in the retina and serum was detected using ELISA.The use of experimental animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results Retinal cell apoptosis was mainly localized to the retinal ganglion cell (RGC) layer.The apoptosis rate of RGCs was (43.4±5.0)％ in the DR model group and (30.0±5.1)％ in the capsaicin pretreated group,showing a significant difference (t =5.930,P＜0.01).Compared with the DR model group and capsaicin pretreated group,the apoptosis rates of the DR control group (12.4±9.9) ％ and the capsaicin control group (17.6-±6.1) ％ were significantly lower (t =8.800,t =4.925,P＜0.01).The apoptosis rate of the plain control group was (16.2±6.9)％,exhibiting significant differences in comparison with the DR control group and capsaicin control group (t =-0.989,t =0.951,P＞0.05).The specific activity of caspase-3 was (2.19±0.86) in the DR model group and (1.96±0.56) in the capsaicin pretreated group,presenting a significant difference (t =-0.515,P＜0.05).Those of the DR control group and capsaicin control group were (1.47±0.14) and (0.74±0.27),respectively,with considerable decline in comparison with the DR model group and capsaicin pretreated group (t=2.142,t=2.797,P＜0.05).The retinal and serum CGRP levels were (424.4±44.2)and (148.8±39.1) ng/L,respectively,displaying significantly lower levels than (543.2±74.4) and (237.5±78.7) ng/L (t =3.070,2.359,P＜0.05) from the capsaicin pretreated group.Conclusions Apoptosis of retinal ganglion cells occurs in the STZ-induced diabetic rats.Pretreatment of capsaicin reduces retinal cell apoptosis,which may be associated with an increase of CGRP in the retina.

Objective To understand the distribution characteristics and drug resistance of bacteria isolated from blood cul‐ture in Xinjiang area during 2013 .Methods The identification of isolated bacteria were performed by adopting the France VITEK‐Compact and the ABI series bacterial identification instruments .The antimicrobial susceptibility test was carried out by using the minimum inhibitory concentration (MIC) and Kirby‐Bauer (K‐B) methods .Results A total of 3 962 strains of bacteria were isola‐ted from clinical blood culture ,in which Gram‐positive bacteria and Gram‐negative bacteria accounted for 50 .8% and 49 .2% respec‐tively .The most frequent strains were coagulase‐negative staphylococci (31 .7% ) ,Escherichia coli (23 .2% ) ,Staphylococcus aureus (9 .5% ) ,Klebsiella pneumoniae (8 .7% ) ,Acinetobacter baumannii (3 .6% ) ,Enterobacter cloacae (2 .5% ) ,Enterococcus faecium (2 .5% ) ,Pseudomonas aeruginosa (2 .2% ) ,Enterococcus faecalis (2 .0% ) and Streptococcus pneumoniae (1 .1% ) .The detection rate of extended‐spectrum beta‐lactamase (ESBLs) producing Escherichia coli ,Klebsiella pneumoniae and Proteus mirabilis were 69 .8% ,62 .6% and 66 .7% respectively .The detection rates of methicillin‐resistant Staphylococcus aureus(MRSA) and methicillin‐resistant coagulase‐negative Staphylococcus (MRCNS) was 36 .2% and 86 .3% respectively .The pan‐drug resistant (XDR) strains of Acinetobacter baumannii ,Pseudomonas aeruginosa ,Klebsiella pneumonia were 14 strains(9 .9% ) ,1(1 .2% ) ,2 strains(0 .1% ) ,16 strains(0 .6% ) .No strains resistant to vancomycin or linezolid were found in Staphylococcus and Enterococcus faecalis .Conclusion Among blood culture isolated bacteria in Xinjiang area ,the proportion of Gram‐positive bacteria and Gram‐negative bacteria have little difference .The diversity of bacterial species exist .The resistance to commonly used antibiotics is serious .The distribution situ‐ation of blood culture isolated bacteria should be timely understood .The bacterial drug resistance monitoring should be strengthened to control the nosocomial infections ,guide rational drug use in clinic and control the generation and spread of drug resistant bacterial strains .

The neonatal resuscitation program consisted of three stages:pilot promotion, provinces promotion and grass-roots promotion in China. Neonatal resuscitation was easy to learn, training forms were various, the duration was different. There were regional differences in the pass rate of examination and standard recovery rate. The neonatal resuscitation training rate, the system execution rate and the equipment rate in primary hospitals was lower than secondary hospitals and tertiary hospitals. The primary hospitals would be the key link of the neonatal resuscitation program. We suggested to build neonatal resuscitation training and treatment system.

Objective To discuss the diagnosis and treatment of inflammatory granuloma in central nervous system(CNS)to provide reference for clinic.Methods Retrospective data included 8 patients with CNS inflammatory granuloma in Department of Neurosurgery,Shanxi People's Hospital,2012 -2015.We analyzed the imaging features, postoperative symptoms,blood and cerebrospinal fluid changes and prognosis.Results 8 cases all received surgical treatment.All the symptoms were improved,and the CT showed that the lesions were disappeared.All the patients had recovered to normal life and work.Conclusion The diagnosis of CNS inflammatory granuloma is difficult.Clinical manifestations are lack of specificity.The blood and cerebrospinal fluid laboratory examination have no abnormal changes.CT and MRI are the main diagnostic methods.Postoperative pathology is the gold standard for diagnosis.The large lesion,frequent episodes of epilepsy,severe neurological deficits and possibility of brain tumor all should be treated by surgery.

60 Gy.The 5-year local control rates are 92%,71% and 87% respectively(P=0.9194),and 5-year overall survival rate are 68%,62% and 53% respectively(P=0.4194).There is no significant difference of overall survival and local control rate between these three dose groups.Five patients with dose of more than 50Gy died of late toxicities.Conclusions:Adjuvant radiotherapy for Stage Ⅱ and Ⅲ patients with rectal cancer dose not show dose response.There is no improvement of local control and survival due to the escalation of dose.The dose of conventional radiotherapy is better at less than 50Gy.Overdosage may lead to severe toxicities.

Objective To investigate the ideal reconstruction methods after pelvic tumor resection and to assess the feasibility of three-dimensional (3D) printing technology for pelvic reconstruction,we performed a retrospective study of patients with pelvic tumors who received tumor resection and reconstruction using 3D-printed pelvic endoprostheses.Methods Thirty-five patients received tumor resection and functional reconstruction with 3D-printed pelvic endoprostheses in our center from Sep.2013 to Dec.2015.According to Enneking' s classification,there were 3 cases of Type Ⅰ,12 cases of Type Ⅱ+Ⅲ,5 cases of Type Ⅰ+Ⅱ,2 case of Type Ⅰ+Ⅱ+Ⅲ,10 cases of type Ⅰ+Ⅱ+Ⅳ and 3 cases of type Ⅰ+Ⅱ+Ⅲ+Ⅳ resection.Methods of reconstruction included 3 patients with 3D-printed iliac endoprosthesis,12 patients with 3D-printed standard hemipelvic endoprosthesis and 20 patients with 3D-printed screw-rod connected hemipelvic endoprosthesis.Results All 35 patients underwent en bloc resection.Margins were wide in 15 cases,marginal in 14 cases and intralesional in 6 cases.After a mean followed-up of 20.5 months (6 to 30),25 patients survived without evidence of disease,5 patients were alive with diseases and 5 patients died of distant metastasis.Complications included 7 cases of delayed wound healing,2 cases of hip dislocation and no cases of deep infection.The average MSTS 93 score was 19.1 (9-26) for all of the 30 alive patients,22.7 (20 to 25) for 3 patients with iliac endoprosthesis reconstruction,19.8 (15 to 26) for 12 patients with standard hemipelvic endoprosthesis reconstruction,and 17.7 (9 to 25) for 15 patients with screw-rod connected hemipelvic endoprosthesis at the last follow up.Conclusion The application of 3D-printing technology could facilitate precise matching and osseointegration between the implants and host bone.Our clinical results proved that application of 3D-printed pelvic endoprostheses for reconstruction of bony defect was safe without additional complications,and that good functional results could be expected during short-term follow-up.
