The surveillance of schistosomiasis in Sanzhou Village, Dantu District, Zhenjiang City, a national schistosomiasis surveillance site, showed that in 2008, the area with snails was 27 hm~2, among which the area with infected snails was 14 hm~2, the densities of living snails and infected snails were 0. 86 and 0.002 1 snails/0. 1 m~2, respectively. The infection rate of snails was 0.25% , the positive rate of IHA was 3. 10% and the infection rate of schistosome in human populations was 1%. There were no infected domestic animals found, and there were no acute schistosomiasis and newly advanced schistosomiasis cases found in the surveillance site in 2008. It is indicated that the endemic situation of schistosomiasis is stable. The comprehensive control, including molluciciding and environmental modification, should be implemented for snail control. The comprehensive measures with emphasis on infectious source control should be further strengthened.

Aim To explore the protective effect of Sertoli cells on the co-transplanted allogeneic renal cells in male and female recipient rats. Methods Testicular Sertoli cells were prepared by digestion with trypsin， collagenase and DNase， while renal cells were prepared by digestion with trypsin alone. FasL and Fas expressions were detected respectively by FCM before transplantation. About 106 cells were injected into the allogeneic renal subcapsule. In order to demonstrate the survival of renal cells， the expression of g-PG in graft was examined by SABC method. Apoptosis of the lymphocytes surrounding the graft was observed by TUNEL(terminal deoxynucleotidyl transferase-mediated X-dUTP nick end labeling). Results The grafts were analyzed histologically 20 days after transplantation. The renal cells transplanted alone were all rejected, while the survival rates of the mixed cell transplantation were 87.5％ and 77.8％ in male and female recipients respectively. When the renal cells co-transplanted with Sertoli cells treated by anti-FasL mAb， only 30.0％ grafts were survived. Apoptosis of lymphocytes surrounding the graft were quite evident. Conclusion Sertoli cells expressing FasL can protect renal cells from allograft rejection by inducing apoptosis of Fas expressing T cells surrounding the grafts.

Objective To evaluate the changes of left atrial structure and function in the patients with atrial fibrillation who accepted bi -polar radio frequency current ablation .Methods All patients in our study were divided into three groups including the ones who had accept -ed bipolar radio frequency current ablation because of atrial fibrillation ,the ones who refused to accept ablation operation in despite of atrial fibrillation and the ones who maintained sinus rhythm before operation .All patients accepted TTE before and after operation .Results The rate of transverse diameter change of ablation group (24.24 ±8.67)%was larger than those of other two groups (P<0.05).Left atrial chan-nel capacity volume change rate of ablation group (17.18 ±3.26)%were larger than the values of the group who were suffering atrial fibrilla-tion but refused ablation advice (0.86 ±0.26)(P<0.05).Left atrial total ejection fractions of ablation group (202.41 ±81.59)%were lar-ger than the values of the group who were suffering atrial fibrillation but refused ablation advice (109.53 ±60.91)%( P<0.05) .And its ac-tive ejection fractions(12.18 ±3.48)%,total ejection fractions(41.31 ±8.26)%and so forth were less than the group who maintained si-nus rhythm before operation(21.33 ±5.61)%,(45.05 ±7.37)%,respectively (P<0.05).Left atrial posterior wall center and cardiac basal segment strain(14.34 ±9.47)%,(13.20 ±8.38)%,respectively,and strain rate values after operation of ablation group were less than other segments .Conclusion Left atrial structure remodeling inversion was not obviously 3~6 months after bipolar radio frequency cur-rent ablation .And at the same time ,the improvement of left atrial storage function was not obviously compared with the group who refused ab -lation advice,left atrial channel function compensation degree descended obviously left atrial co -pumping function in ablation group increased obviously,left atrial posterior wall center and cardiac basal segment systolic and distolic function were less than other segments of left .

Intraoperative cell salvage (IOCS) has been widely used to reduce allogeneic blood transfusion and prevent blood transfusion related complications during surgery.However, due to the risk of transfusion related reaction, contamination, and immunological reaction, its use for tumor patients has been controversial and limited.To explore the feasibility of the application of IOCS in cancer patients, we reported 2 cases of renal cell carcinoma (RCC) with tumor embolism in IVC that underwent radical nephrectomy,and inferior caval venous thrombectomy receiving IOCS combined with leukocyte depletion filter (LDF) from August 2016 to November 2016 in our hospital.The cell saver blood salvage (Haemone-tics, 5+) was used for these 2 cases.The salvaged blood was filtered through the LDF before infusion.For case 1 (male 45-year-old) the total operation time was 505 min, and the estimated blood loss was 4 500 ml.A total of 1 000 mL autologous blood, 12 u allogeneic packed red blood cells (PRBC), 1 200 mL fresh frozen plasma (FFP) were infused during the procedure.The patient was discharged from hospital after 75 days without complications.The postoperative follow-up for 3 months showed no tumor recurrence or metastasis.For case 2 (a male patient, aged 51 years), the total operation time was 490 min, and the estimated (blood loss was 7 000 mL.the patient received 2 700 mL autologous blood transfusion, 12 u allogeneic packed red blood cells (PRBC), and 2 400 mL fresh frozen plasma (FFP).The patient was discharged from hospital after 86 days without severe complications.the postoperative follow-up for 6 months showed no tumor recurrence or metastasis for this patient.Other relevant retrospective studies with this technique showed that cell salvage could be used safely in many kinds of cancer patients, for example, bladder cancer, liver cancer and kidney cancer.Furthermore,numerous researches have proved the safety and efficacy of the combination of these two techniques, the intraoperative cell salvage technique and leucocyte depletion filter in cancer patients.Here we only reported two cases using IOCS and LDF.Further work is needed to determine whether the use of intraoperative cell salvage combined with leukocyte depletion filter can be used safely for patients with HCC.

Objective To observe the effect of electroacupuncture and nerve and tendon gliding exercises on mild to moderate carpal tunnel syndrome.Methods Forty patients with mild to moderate carpal tunnel syndrome were randomly divided into an observation group and a control group,each of 20.Both groups were given neurotrophic drugs.The observation group was additionally provided with electroacupuncture and nerve and tendon gliding exercises,while the control group was given routine health education for 4 weeks.The Boston carpal tunnel syndrome questionnaire (BCTQ),a visual analogue scale (VAS),thumb and middle finger to wrist motor conduction velocity (MCV),sensory nerve action potentials (SNAPs),median nerve distal motor latency (DML) and the amplitude of compound muscle action potential (CMAP) of the musculi abductor pollicis brevis were evaluated.Results There were no significant differences in any of the measurements between the two groups before the treatment.After four weeks of treatment,significantly better improvement was observed in the average SCV of the thumb and wrist,the SCV of the digitus medius and wrist,the SNAP of the thumb and wrist,the SNAP of the digitus medius and wrist,the DML of the nervus medianus and the CMAP of the abductor pollicis brevis in the observation group compared to before the treatment and compared to the control group.Moreover,there was a significant decrease in the observation group's average BCTQ symptom score and function score and in their VAS ratings.However,in the control group significant differences were only found in the average SCV of the thumb and wrist,the DML of the nervus medianus and in their VAS ratings.Conclusions Electroacupuncture and nerve and tendon gliding exercises can significantly relieve symptoms and restore hand function.They are worth applying in clinical practice.
