Haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) has been an alternative source of stem cell transplantation,the successful application of which makes each transplant candidate has his/her donor.In this paper,advances in the Haplo-HSCT reported in the 56th American Society of Hematology (ASH) annual meeting are reviewed.

Increasing detection of unruptured intracranial aneurysms,catastrophic outcomes from subarachnoid hemorrhage,and risks and cost of treatment necessitate defining objective predictive parameters of aneurysm rupture risk.However,long-term follow-up have shown the risk of intracranial aneurysm rupture is associated with its morphologic characteristics,hemodynamic factors and patient's own situation.

Objective To investigate the effect of hypoxia on expressions of erythropoietin(EPO)mRNA and protein in retinal M?ller cells cultured in vitro. Methods Retina tissues from the new-born Wistar rats were dissected into cell suspension after digested by pancreatin.M?ller cells were separated and purified by mechanical concussion and blowing and striking method.The expression of EPO mRNA and protein under the condition of hypoxia was detected by semi-quantitative reverse transcriptase(RT)-polymerase chain reaction(PCR)and immunocytochemical method. Results Retinal M?ller cells were cultured successfully,95% of which were positively stained by glial fibrillary acidic protein(GFAP).Positively stained EPO protein was located in the cytoplasm and protuberance.The expression of EPO mRNA and protein was faint in the normal retinal M?ller cells,but increased obviously and time-dependently after hypoxia. Conclusion Expression of EPO mRNA and protein increases in M?ller cells after hypoxia,which may be one of the protective factors for the nerves in anoxic retinopathy.

OBJECTIVE To understand the relevant factors of nosocomial infection of inpatients in order to provide the evidence for taking measures to prevent and control the infection effectively.METHODS A retrospective survey was carried out on 10059 cases of hospitalized patients during Jan and Dec of 2008.RESULTS The nosocomial infection rate of hospitalized patients in this period was 4.3%(437/10059).The high risk infected rates were respectively as follows:24.9% in the Blood Department,15.1 % in the Tumor Department;The infection site were respiratory tract(59.3%),urinary tract(14.3%);The main pathogens were Gram negative bacteria(40.7%),fungus infection(25.4%);The risk factors mainly were usage of antibiotic drugs(40.7%),and underlying diseases of tumor(16.2%).CONCLUSIONS The effective measures for reducing the incidence of nosocomial infection should be taken.More attention should be paid on the risk factors.

This study aimed at optimizing the extraction process of Bi Xie Fen Qing (BXFQ) drink using ultrasound-microwave cooperation with central composite design-response surface method in comparison with the traditional decoction process.Taking microwave frequency,amount of water,extraction time as the main detection factors,diosgenin,glycyrrhizic acid and the extract yield were tested as the evaluation indexes;and taking an integrated score as response value for response surface and contour,predictive analysis was carried out and the optimum extraction conditions were achieved.It was found that the optimum extraction process of BXFQ drink was identified:the microwave frequency was 434 W,water addition was 18.4 times,extraction time was 9.3 mins and the ultrasonic frequency was fixed at 50 W.Under the optimum process,the diosgenin extraction yield rate was 23.17％ (mg· g-1),extraction yield rate of glycyrrhizic acid was 0.64％ (g·g-1),and the extraction yield rate of extractum was 34.12％ (g·g-1).All the indexes were superior to those of the traditional method.It is concluded that the composite design-response surface method is suitable for the extraction optimization of BXFQ drink with favorable predictability of the mathematical model.The optimized ultrasoundmicrowave cooperation was easy to operate with high extraction efficiency.It is suitable for industrialized production with the provision of a scientific reference for the modern formulation development of BXFQ drink.

Aim To study the characteristics of KCNQ2/3 potassium channel expressed in CHO cells and its modulation by M_1 receptor.Methods KCNQ2 and KCNQ3 potassium channels and M_1 receptor were co-expressed in CHO cells.Whole cell patch-clamp techniques was used to observe the characteristics of KCNQ2/3 current,its modulation by the M_1 receptor,and the effects of the common potassium channel blockers.Results KCNQ2/3 current recorded in CHO cells was a slow-activation low-threshold non-inactivating,voltage-dependent outward potassium current.KCNQ2/3 current was elicited at about-60 mV,V_(1/2)(-26.8?1.2) mV and the deactivation current fitted two exponential function,with ?_(fast) of 101ms and ?_(slow) of 309 ms.The channel was not sensitive to common pharmacological blockers such as 4-AP,Ba~(2+) and TEA,but was inhibited significantly by linopirdine,with a IC_(50) of(6.5?0.83) ?mol?L~(-1).Acetylcholine suppressed the KCNQ2/3 current reversibly via M_1 receptor,with a IC_(50) of(0.7?0.05) ?mol?L~(-1).Conclusion KCNQ2 and KCNQ3 channels are the molecular basis of M-current observed in neuronal cells.KCNQ2/Q3 current expressed in CHO cells has similar characteristics as that seen in neuronal M-current.Linopirdine is a powerful blocker of KCNQ2/3 channel and acetylcholine inhibits the current by muscarinic M_1 receptor.This experiment has laid a solid basis for further study of M-current and KCNQ2/3 current,and is important for the study of neurological diseases relating to alteration of M-current,such as convulsion,epilepsy and Alzheimers disease.

Objective: To observe the preventive effect of taurine on alcoholic liver damage in rat.Methods: The model was induced by filling stomach with alcohol, and the treatment groups were given two different concentrations of taurine, and the control group was given 0.9%NS, then we measured the blood triglycerides (TG), and the pathological changes of liver quantitatively.Results: Two different le-vels of taurine can significantly decrease the level of TG and ameliorate the liver damage of rats (P0.05), and the 5% taurine group can also decrease the mean arterial pressure (P

Objective:To explore the feasibility and efficacy of laparoscopic resection of abdominal and retroperitoneal cystic masses in children.Methods:A retrospective analysis of 11 cases of abdominal and retroperitoneal cystic masses in Department of Pediatric Surgery, Quanzhou First Hospital Affiliated to Fujian Medical University from June 2015 to January 2019 was performed, and all the patients underwent laparoscopic resection or laparoscopic-assisted resection, with 6 cases of boys and 5 cases of girls, aged 8 months to 10 years (with the average of 59 months). Meanwhile, 9 cases were from the abdominal cavity and 2 cases were from the retroperitoneum.Results:All patients underwent laparoscopic or laparoscopic-assisted resection without switching to laparotomy.The operation time was 60-210 minutes, with the average of 120 minutes.The intraoperative blood loss was 5-30 mL, with the average of 10 mL.There was no blood transfusion.All patients were discharged 3-8 days after surgery, with the average of 5 days.The postoperative pathological results included 5 cases of mature teratoma, 1 case of paraneoplastic cyst, 2 cases of intestinal duplication, 2 cases of lymphangioma, and 1 case of hepatic cyst.Totally, 11 cases were followed up for 7-51 months, with the average of 20.9 months.No recurrence occurred.Conclusions:Laparoscopic or laparoscopic-assisted resection of abdominal and retroperitoneal cystic masses has advantages of minimal invasion, rapid recovery in children, and it is safe and effective.
