The improvement and trend of group I was slightly better than other 9 groups,without statistical significance(P>0.05). There was no statistical significance in the incidence of ADR among 10 groups(P>0.05). CONCLUSIONS:Bencycloquidium bromide nasal spray with 90 μg,qid times significantly improves rhinorrhea score and continuous rhinorrhea duration with good safety.

This study was aimed to explore a simple and applicable method of separating mature sperms from human testicular tissue for intracytoplasmic sperm injection and embryo transfer. The suspension of human testicular tissue was cultured in 10% human serum albumin and human tubule fluid with different concentrations (0 u/ml; 50 u/ml; 100 u/ml; 150 u/ml; 200 u/ml) of hyaluronidase for 24 h, and then the Percoll gradient centrifugation was processed to separate the sperms; meanwhile the sperms were counted and graded according to their motility. The difference in quality and quantity among the groups and the difference between the groups and the zero-hour culturing group were detected. It was shown that the four hyaluronidase-treated groups contained large quantity and high quality of sperms as compared with the two contrast groups (P<0.01). The groups in the solution of 50 u/ml, 100 u/ml and 150 u/ml concentrations of hyaluronidase had almost the same amount of sperms that displayed higher motility as compared against the sperms in the group treated with 200 u/ml concentration of hyaluronidase (P<0.01). There was no difference between the two contrast groups (P>0.05), or among the groups treated with 50 u/ml, 100 u/ml, and 150 u/ml of hyaluronidase concentration (P>0.05). This method of adopting hyaluronidase with Percoll gradient centrifugation in the process for separating mature sperms from human testicular tissue is applicable. It can increase the quantity and quality of sperms separated from testicular tissue suspensions when adequate concentrations of hyaluronidase is used.

To optimize program of bovine somatic nuclear transfer, we used two different enucleation procedures (by Spindle-view system & Hoechst 33342 staining), two different procedures to introduce donor nuclei (by ooplasm microinjection & electrofusion), and three different group electrofusion parameters (group 1: 1.9 kV/cm, 10 micros, two; group 2: 1.5 kV/cm, 25 micros, two; group 3: 0.6 kV/cm, 100 micros, one) to reconstruct bovine cloned embryos. The cleavation rates and blastocyst development rates of cloned embryos were used to assess the efficiency of different operational procedure. Finally, the best combination of operational procedure, that the spindle-viewer system was used for oocytes enucleating, and donor cell was electrofused into ooplasm by electrical pulse (1.9 kV/cm, 10 micros, two) to reconstruct bovine cloned embryos. Then the excellent blastocysts were transferred to fosters for producing cloned cattle 80 high-quality cloned blastocysts were transferred into 33 fosters, two cloned calves were produced. According to the results, the optimized program could be used to produce cloned cattle.

Morulaes and blastocysts obtained from Guanzhong dairy goats 6-7 days after mating were treated with whole embryo cultivaton, enzymatic digestion and immunosurgery separately. The goat embryonic stem cells (ESC) were isolated and cultured on a feeder layer of mitomycin-inactivated mouse embryo fibroblasts (MEF). The characteristics of goat ESCs were analyzed by immunohistochemisty, RT-PCR and inducing differentiation in vitro. The results indicated that the embryos were easier to attach the culture dish and form primary colonies with whole embryo method. There were colonies that maintained undifferentiated for 18 passages. The ESCs expressed the protein of Nanog, Oct4 and SSEA-3, whereas the protein of SSEA-4 was absent and the protein of SSEA-1 was weakly expressed. In addition, the genes of Nanog, Oct4, TERT and CD117 were expressed in goat ESCs. The cells also could differentiate to myocardial cells when induced in vitro by DMSO. These results suggest that the goat ESCs have characteristics of ESCs.

Objective:To validate the feasibility of the gamma analysis method in the study of prescription dose conversion between logistic nanodosimetry model (LNDM) and microdosimetric kinetic model (MKM) basing on the Chinese self-developed model LNDM by applying clinical experiences of National Institute of Radiological Science (NIRS).Methods:Physical dose distributions derived from the MKM- and LNDM-based carbon ion treatment plans were compared via the method of gamma analysis under the open-source treatment planning platform matRad. In this way, the prescribed dose conversion factor between the MKM- and LNDM-based treatment plans was obtained. Using water phantoms, the influence of geometric shape, size, depth of target volume (TV), prescribed dose and field setting on the conversion factor was investigated comprehensively. Moreover, preliminary verification of the acquired conversion factor was conducted on the C-shape model and a case of liver cancer patient.Results:The conversion factor depended on the field setting rather than the TV shape. Under the condition of single field, the conversion factor was positively correlated with the size and depth of TV, and the prescribed dose. Moreover, the conversion factor was successfully verified using the C-shape model and the patient with liver cancer, where the gamma passing rates (2%/2 mm) of the physical dose distribution generated by the MKM and LNDM treatment plans were 92.79% and 91.19%, respectively.Conclusions:The conversion factors (f=D LNDM/D MKM) obtained in this study might provide guidance for the prescribed dose setting during the carbon ion treatment planning based on the LNDM. Besides, the gamma analysis method could be used for the study of the prescribed dose conversion between different models.

Objective: To investigate the clinical value of laparoscopic peritoneal dialysis catheter implantation in peritoneal chemotherapy for gastric cancer with peritoneal metastasis. Methods: From January 2019 to June 2019, the clinical data of 6 patients diagnosed as gastric cancer with peritoneal metastasis were retrospectively analyzed in the Gastrointestinal Surgery Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine. Five were male and 1 was female. The median age was 69.5 (28-77) years. The median body mass index (BMI) was 22.8 (19.6-23.5). All procedures were performed under general anesthesia with endotracheal intubation. The patient′s body position and facility layout in the operating room were consistent with those of laparoscopic gastrectomy. The operator′s position: the main surgeon was located on the right side of the patient, the first assistant stood on the left side of the patient, and the scopist stood between the patient′s legs. Surgical procedure: (1) trocar location: three abdominal trocars was adopted, with one 12 mm umbilical port for the 30° laparoscope (point A). Location of the other two trocars was dependent on the procedure of exploration or biopsy as well as the two polyester cuff position of the peritoneal dialysis catheter: Usually one 5 mm port in the anterior midline 5 cm inferior to the umbilicus point was selected as point B to ensure that the distal end of the catheter could reach the Douglas pouch. The other 5 mm port was located in the right lower quadrant lateral to the umbilicus to establish the subcutaneous tunnel tract, and the proximal cuff was situated 2 cm away from the desired exit site (point C).(2) exploration of the abdominal cavity: a 30° laparoscope was inserted from 12 mm trocar below the umbilicus to explore the entire peritoneal cavity. The uterus and adnexa should be explored additionally for women. Once peritoneal metastasis was investigated and identified, primary laparoscopic peritoneal dialysis catheter implantation was performed so as to facilitate subsequent peritoneal chemotherapy. Ascites were collected for cytology in patients with ascites. (3) peritoneal dialysis catheter placement: the peritoneal dialysis catheter was introduced into the abdominal cavity from point A. Under the direct vision of laparoscopy, 2-0 absorbable ligature was reserved at the expected fixation point of the proximal cuff (point B) for the final knot closure. Non-traumatic graspers were used to pull the distal cuff of peritoneal dialysis catheter out of the abdominal cavity through point B. The 5-mm trocar was removed simultaneously, and the distal cuff was fixed between bilateral rectus sheaths at the anterior midline port site preperitoneally. To prevent subsequent ascites and chemotherapy fluid extravasation, the reserved crocheted wire was knotted. From point C the subcutaneous tunnel tract was created before the peritoneal steath towards the port site lateral to the umbilicus. Satisfactory catheter irrigation and outflow were then confirmed. Chemotherapy regimen after peritoneal dialysis catheterization: all patients began intraperitoneal chemotherapy on the second day after surgery. On the 1st and 8th day of each 3-weeks cycle, paclitaxel (20 mg/m²) was administered through peritoneal dialysis catheter, and paclitaxel (50 mg/m²) was injected intravenously. Meanwhile, S-1 was orally administered twice daily at a dose of 80 mg·m^-2·d^-1 for 14 consecutive days followed by 7-days rest. To observe the patients′ intraoperative and postoperative conditions. Results: All the procedures were performed successfully without intraoperative complications or conversion to laparotomy. No 30 day postoperative complications were observed. The median operative time was 33.5 (23-38) min. The median time to first flatus was 1(1-2) days, and the median postoperative hospital stay was 3 (3-4) days, without short-term complications within 30 days postoperatively. The last follow-up was up to July 10, 2019, and the patients were followed for 4(1-6) months. No ascites extravasation was observed and no death occurred in the 6 patients. There was no catheter obstruction or peritoneal fluid extravasation during and after chemotherapy. Conclusion Laparoscopic peritoneal dialysis catheter implantation was safe and feasible for patients with peritoneal metastasis of gastric cancer. The abdominal exploration, tumor staging and the abdominal chemotherapy device implantation can be completed simultaneously, which could simplify the surgical approach, improve the quality of life for patients and further propose a new direction for the development of abdominal chemotherapy.

Post-traumatic stress disorder(PTSD),as a mental disorder disease,can seriously damage the physical and mental health and social functioning of patients.Physical therapy is increasingly being used in research on the treatment of PTSD due to its ability to directly target specific brain regions and improve the core symptoms of PTSD.This review categorizes on physical therapy for PTSD into two categories:non-invasive physical therapy and invasive physical therapy.Non-invasive physical therapy methods included electroconvulsive therapy,transcranial direct current stimulation,transcranial magnetic stimulation,and the Flexyx neurotherapy system.Non-invasive physical therapy had the advantages of safety,convenience,and simple operation.However,their stimulation accuracy was limited.Invasive physical therapy methods included deep brain stimulation and stellate ganglion block.Invasive physical therapy had the advantages of precise stimulation,fewer adverse reactions.However,there were surgical risks,high operational difficulty,and high treatment costs.In addition,potential physical therapy methods included transcranial alternating current stimulation,magnetic seizure therapy,and vagus nerve stimulation,which were currently in the theoretical research stage.This study discussed the mechanism of action,therapeutic parameters,clinical efficacy,adverse effects and the latest forms of technology of the above physical therapy methods,so as to provide reference for the treatment of PTSD.
