Objective To improve the awareness of rare mixed prostatic carcinoma. Methods We reviewed the clinical data of 5 patients with prostatic mixed tumor and relevant literature to ex-plore diagnosis and treatment for it. Results Patient 1 with mixed small cell carcinoma and adeno-carcinoma of the prostate who underwent transurethral electrovaporization of the prostate (TUVP) and flumamide therapy died of lung metastasis 7 months later. Patient 2 with mixed small cell carcinoma and adenocarcinoma of the prostate who underwent TUVP and bilateral testicular resection died of lung metastasis 10 months later. Patient 3 with adenosquamous carcinoma of the prostate who underwent TUVP, radiation therapy and flumamide therapy died of multiple organ failure 8 months later because of the lung, liver, and multiple bone metastasis. Patient 4 with prostatic adenosquamous carcinoma who underwent cystoprostatectomy combined with urinary diversion has already survived for 1 year. Patient 5 with prostatic carcinosarcoma who underwent cystoprostatectomy, urinary diversion, pelvic lymphadenectomy, and radiation therapy died of lung metastasis 13 months later. Conclusion Mixed prostatic carcinoma is quite aggressive with bad prognosis. Its diagnosis relies on detailed pathological examination and immunohistochemical techniques. Patients with prostate adenocarcinoma should be followed up timely after endocrine treatment or radiotherapy. Radical surgery is most effective for mixed prostatic carcinoma.

Objective To investigate the epidemiology and clinical features of epidemic cerebrospinal meningitis of children in Shanghai area in the last 2.5 years. Methods A retrospective study was conducted in 27 hospitalized patients with epidemic cerebrospinal meningitis by analyzing the clinical manifestation,epidemiology and laboratory test fingdings from Jan.2006 to Jun.2008.Statistical analysis of the clinical manifestations of cases in serogroup A,B and C was performed according to Neisseria meningitidis infection. Results There were sporadic cases of children with epidemic cerebrospinal meningitis in Shanghai area in the last 2.5 years.The seasonal distribution illustrated the peak occurrence from Feb.to Apr.Among all these cases,92.6% were floating children.Common types(74.1%) were the predominant clinical manifestations and the others were fulminate types(25.9%).Four cases in each of serogroup A and B,and 8 cases of serogroup C were identified by serotyping on 14 Neisseria meningitidis strains and genotyping on the other 2 cases′ cerebrospinal fluid specimens.All the patients in serogroup A with meningococcal diseases were not vaccinated before and 25.0% of them belonged to fulminate types.Half of the cases had petechia on the skin and the prevalence of skin necrosis was 25.0% and 50% had complications of nervous system.No fulminate type was present in cases of serogroup B meningococcal disease and only 1 case had slight petechia on the skin.However,intensive convulsions occurred in 75.0% of the patients,and all of them had complication of nervous system,with a few had sequela.Among the patients in serogroup C meningococcal disease,62.5% patients were vaccinated with serogroup A Neisseria meningitidis.In serogroup C,Neisseria meningitidis infection was found in each age group,with petechia on skin,skin necrosis,immunity correlation fever and complications of nervous system in 87.5%,50.0%,75.0% and 12.5% of the patients,respectively. Conclusions 1.Epidemic cerebrospinal meningitis occurred sporadically in children in Shanghai area,the majority of patients were floating populations.2.Clinical manifestation was typical in patients of serogroup A meningococcal disease.Subdural effusion or ventricalitis was more common in patients of serogroup B meningococcal disease.In serogroup C,Neisseria meningitidis was the most prevalent serotype leading to epidemic cerebrospinal meningitis.More cases were found in patients infected with serogroup C,Neisseria meningitidis with severe shock and immunity correlation fever compared with the other groups.Prophylactic vaccination of serogroup C polyvalent meningococcal organism should be recommended.

This article reviews the clinical application value and limitation of thrombelastography in patients with ischemic cerebrovascular disease.

Objective To evaluate the cross-screws fixation for displaced radial neck fractures.Methods A total of 29 patients with displaced radial neck fracture (Mason type Ⅱb) were treated by open reduction and cross-screws fixation at our department from October 2009 to August 2012.They were 18 males and 11 females,aged from 18 to 56 years (average,37.2 years).The fractures affected 16 left and 13 right sides.The time from injury to operation was from 3 to 72 hours,with an average of 33.9 hours.All fractures were displaced by more than 2 mm or angulated by more than 30°,and caused by simple falling.The elbow function was evaluated by the Broberg & Morrey scoring system at one year postoperation.Results All the 29 patients were followed up for an average of 16 months (range,from 12 to 29 months).All fractures healed within 3 months,ranging from 4 to 12 weeks (mean,10.6 weeks).By the Broberg & Morrey scores at one year postoperation,15 patients were rated as excellent,10 as good,3 as fair and one as poor,giving an excellent to good rate of 86.2％.No wound infection,neural injury,fracture displacement or fixation failure occurred.No implants were removed due to local uneasiness.Conclusion Cross-screws fixation can achieve satisfactory outcomes for radial neck fractures.

Objective To obeserve the effects of acute hypervolemic hemodilution(AHH) with hypertonic .sodium chloride hydroxyethyl starch 40(HSH 40) on hemodynamics and fluid balance in patients under general anesthesia.Methods Fifty patients undergoing radical surgery for gastral cancer under general anesthesia were randomly divided into 2 groups with 25 patients each.Acute hypervolemic bemodilution (AHH) was performed with HSH 40 6 ml/kg in group A or with hydroxyethyl statch(HES) 6 ml/kg in group,which was infused within 30 minuts.HR,MAP,CVP were recorded before(T_0),at 30 min (T_1),60 min (T_2) after infusionand and the end of operation (T_3).The amounts of bleeding,HSH 40 and HES and urine output were recorded as well.Results There were no significant diferences in HR and MAP between two groups at all time points.CVP was sighificantly higher at T_1-T_3 than that at To in two groups.The urine output was more in groups A than that in group B(P<0.05).Conclusion AHH with HSH 40 can effectively expand blood vlume and increase urine output in surgical patients under general anesthesia.

Objective To investigate the effect of recruitment maneuver(RM) on surfactant proteins in young piglets with acute lung injury and the possible mechanisms of lung recruitment after RM.Methods The piglet model of ALI was established by lipopolysaccharide intravenous injection,12 male piglets were randomly divided into two groups:conventional ventilation group(control group) and RM with low tidal volume group(RM group).After 8 hours of ventilation,mRNA expression of surfactant protein-A(SP-A),SP-B,SP-C,SP-D in the piglet lungs were determined by real time PCR and SP-A protein distribution was assessed by immunohistochemistry.Biochemical analyses of TP,total phospholipids(TPL),DSPC were conducted as well.SP-A levels in bronchoalveolar lavage fluid(BALF) and plasma were measured by enzymelinked immunosorbent assay(ELISA).Results As compared with control group,RM group had higher expression of SP-A,SP-B,SP-C and SP-D.SP-A average gray values of control group and RM group were 97.8±6.4 and 106.3±8.5,and there was significant difference(P＜0.01).RM group showed significant increase of TPL,DSPC and DSPC/TP.The concentration of SP-A in BALF was higher in RM group than that of the control group,however,SP-A plasma level was lower in RM group than that of the control group.Conclusion RM can increase suffactant protein expression in ALI animals,alleviate surfactant protein dysfunction and regulate the concentration of SP-A,which may improve alveolar recruitment following the RM and alleviate ventilator-induced lung injury.

Objective To study the role of the expression of P-selectin and intercellular adhesion molecule-1(ICAM-1) in hamster to rat concordant cardiac xenotransplantation.Methods Intra-(abdominal) cardiac transplantation was performed by using SD rats as recipients of Golden Syrian(hamster) hearts.The rats were divided into 4 groups randomly: group I(n=15),unmodified(recipients) were used as control; group II(n=15),splenectomy at day 0;group III(n=15),the rats were treated with cyclosporine A(CsA) 10 mg/kg every day from day 0;group IV(n=15),splenectomy in combined with CsA.The survival of hamster hearts was observed in each group.The xenograft was harvested at rejection and scheduled time in accordance with the experimental design,and analyzed for histology.The expression of P-selectin and ICAM-1 was detected by immunohistochemistry in xenograft after xenotransplantation.Results The mean survival time of the xenograft in group IV was 34.20?8.98 days,which was significantly longer in groups I,II and III (P

Objective: To determine whether 3-dimentional CT scans is able to effectively improve the detection rate of AO B3 distal radius fractures in clinics.Methods: From Jan 2013 to Jan 2014, 30 patients with distal radius fractures were retrospectively enrolled in this study, all the patients directly visited the skeletal trauma emergency department in Beijing Jishuitan Hospital post injury and all of them accepted open reduction and internal fixation of distal radius fractures at last.All the radiographic data including X ray films and 3-dimentional CT scans of these patients were collected.Two independent observers were required to make primary AO classifications for each fracture by X rays at first, then to make final AO classifications by 3-dimentional CT scans.Finally, the detection rates of CT scans and plain films for AO B3 distal radius fractures and B3.3 distal radius fractures were compared, the agreements of the two methods for diagnosing AO B3 and B3.3 fractures were calculated by Cohen''s Kappa calculations.Results: All the 30 fractures were confirmed to be AO B3 distal radius fractures intraoperatively, and 10 of them were B3.3 fractures.The results were completely consistent with the results of 3-dimensional CT scans.However, only 80%(24/30) AO B3 distal radius fractures and 60%(6/10) B3.3 distal radius fractures could be diagnosed only by X rays.The detection rate of CT scans was proved to be significantly higher than X rays for diagnosing B3 distal radius fractures(100% vs.80%,P<0.05), the detection rate of CT scans was also proved to be significantly higher than that of plain films for detecting B3.3 distal radius fractures(100% vs.60%,P<0.05).The agreement of 3-dimentional CT scans and X ray was poor for detecting both the AO B3 distal radius fracture and B3.3 distal radius fracture (kappa=0).Most importantly, in the study process, two special kinds of B3 distal radius fracture were initially found and described by us.One was named as radial B3 fracture, and the other was named as ulna B3 fracture.Conclusion: 3-dimentional CT scans can effectively improve the detection rate of B3 and B 3.3 distal radius fractures, and also help find two special kinds of B3 fractures.
