Objective To discuss the feasibility,efficiency and safety of urokinase application in patients with hypertensive intraventricular hemorrhage.Methods Sixty-nine patients were included,30 treated with ventricular drainage alone and 39 receiving adjunctive intraventricular urokinase.CT images and ADL scores were compared between the two groups.Results The intraventricular thrombolysis with urokinase significantly hastened the resolution of intraventricular blood clots as compared with ventricular drainage alone(P=0.030),with better outcome(P=0.029).Conclusion Urokinase application is a simple,effective,and safe in managing hypertensive intraventricular hemorrhage.

BACKGROUND:For autoimmune diseases, it is difficult to effectively solve the lack of immunological tolerance in patients by traditional treatments. Mesenchymal stem cells have the biological functions of tissue and organ regeneration and immune regulation. OBJECTIVE:To explore the effects and mechanisms of human umbilical cord-derived mesenchymal stem cells on the development of thymus in nude mice. METHODS:Human umbilical cord-derived mesenchymal stem cells were intraperitoneal y injected into BABL/c nude mice at a dose of 2×106 per mouse. We analyzed the maturation and distribution of thymic epithelial cells in the thymus rudiment of nude mice and the thymopoiesis of this newly developed thymus rudiment;furthermore, we explored the therapeutic effects of human umbilical cord-derived mesenchymal stem cells. RESULTS AND CONCLUSION:Our data showed wel-organized cortex-medul a structure and an obvious improvement in the maturation of thymic epithelial cells in the rudiment. We further demonstrated the improved thymopoiesis and the enhanced export of mature T cells with the T regulatory cells increase in peripheral blood. Furthermore, we found that human umbilical cord-derived mesenchymal stem cells could be engrafted in the thymus and express many cytokines, especial y keratinocyte growth factor which is essential for the thymus development. These findings indicate that a new mechanism of human umbilical cord-derived mesenchymal stem cells can provide a proper microenvironment for the reconstitution and functional maturation of thymus in nude mice, and elicit another insight in terms of therapeutic efficacy of human umbilical cord-derived mesenchymal stem cells in many autoimmune diseases.

Objective To investigate the current status of family rehabilitation for children with disability and the unmet needs of habilitation/rehabilitation for their parents. Methods Family Rehabilitation Needs Survey Questionnaire was used to investigate 186 families of the children with disability from 5 rehabilitation institutions in 4 provinces. Results Most families accepted family rehabilitation, including family support, developed rehabilitation scheme, telephone counseling, real-time guidance and appointment for family rehabilitation. Most families would spent 1-2 hours a day for the family rehabilitation, and prefer the rehabilitation of gross motion. However, the rehabilitation agencies played less importance on supports of family rehabilitation. Conclusion The family rehabilitation supports needs to be improved in specification of rehabilitation process, developing rehabilitation scheme and quality control.

The role of arginine vasopressin ( AVP) played in proliferation and differentiation of mouse primary osteoblast and its mechanism was investigated. 100 nmol/ L AVP was added into the medium containing primary mouse osteoblast: (1) After being cultured for 72 h, the proliferation of the cells was counted with a cell counter. (2) The media of cultured cells on 2,4,6,8,10 days were harvested and tested for the secreted ALP concentration by osteoblasts, and the cells were lysed in order to test the ALP concentration in cytosol. (3) The alizarin red staining was employed to detect the effect of AVP on calcium nodules formation on 8 th and 20 th days. (4) The osteoblast cells were incubated with AVP for 20 min, and then were lysed. Radioimmune assay was applied to test the change of cAMP in cytosol. These results showed that, compared to negative group, 100 nmol/ L AVP significantly promoted the proliferation of primary mouse osteoblast ( P<0. 01). ALP secretion was increased remarkably ( P <0. 01), and the number and area of calcium nodules were increased considerably(P<0. 01). The intracellular cAMP was increased after incubating cells with AVP for 20min ( P<0. 01). These results suggest that AVP may promote proliferation and differentiation of mouse primary osteoblasts by cAMP signal pathway.

Intrahepatic cholangiocarcinoma is a malignant tumor that originates from the bile duct above the confluence of left and right hepatic ducts, and is one of the commonest types of primary liver cancer. The early symptoms of intrahepatic cholangiocarcinoma are not obvious, most patients with non-specific abdominal symptoms in the advanced stage. CT, MRI, etc. are helpful for diagnosis, but most patients are in advanced stage when they are diagnosed. Hepatectomy is the main treatment, radiotherapy, chemotherapy are significant adjuvant treatment, and the overall prognosis is poor. This article reviews the current status and progress in diagnosis and treatment of intrahepatic cholangiocarcinoma.

Mesenchymal stem cell (MSC) has been shown to attenuate injuries in a variety of radiation animal models and has been explored for the treatment of radiation-induced patients, due to its potent immunomodulatory and tissue repair capabilities. Based on its high safety and multiple biological functions, MSC is expected to be used for the treatment of radiation sickness. In this review, the research progress of MSC and its secretions in the treatment of radiation-induced injuries was summarized, such as skin injury, intestinal injury, brain injury, acute radiation syndrome of the hematopoietic system, lung injury, liver injury, and cardiac injury.

Objective To explore the comparison of the clinical efficacy of laparoscopic cholecystectomy based on propensity score matching through the umbilical single hole method and three holes method in the treatment of acute cholecystitis.Methods 106 patients with acute cholecystitis who underwent laparoscopic cholecystectomy in our hospital from January 2020 to December 2022 were selected as research subjects.According to different treatment methods,they were divided into the study group(n=64)and the control group(n=42).The patients in the study group were treated with single port via umbilical laparoscopic cholecystectomy,while the control group was treated with three port laparoscopic cholecystectomy.Compare the surgical related indicators,postoperative recovery,and postoperative complications between the two groups of patients.Results Comparing the general information of the two groups of patients,there was no significant difference in body mass index(BMI),BMI,and gallbladder ultrasound results(P＞0.05),but the average age of the study group patients was greater than that of the control group patients(P＜0.05).By comparing the general data of the two groups of patients after propensity score matching,it was found that there was no significant difference in gender,age,BMI,and gallbladder ultrasonography results between the two groups(P＞0.05).The surgical time for the study group patients was(61.48±10.24)minutes,while for the control group,it was(40.42±8.35)minutes;And the visual analog scale(VAS)scores at 6 and 24 hours after surgery were(5.63±1.04)and(3.42±0.65)for the study group,respectively,while(7.22±1.61)and(5.48±1.02)for the control group.The pain sensation was more pronounced(P＜0.05);However,there was no statistically significant difference in blood loss during surgery between the two groups of patients(P＞0.05).The hospitalization time and gastrointestinal function recovery time of the study group patients were(2.05±0.42)days and(33.46±4.30)hours,respectively,while the control group was(3.95±1.02)days and(47.58±7.62)hours,respectively;And the satisfaction score of the study group patients with incision scars was(4.58±0.42)points,while the control group was(3.02±0.38)points(P＜0.05).The total incidence of complications in the study group was 2.78％,while in the control group it was 16.67％,significantly lower in the study group(P＜0.05).Conclusion Patients with acute cholecystitis treated with the umbilical single hole method have significantly lower postoperative pain,shorter hospital stay,and recovery time of gastrointestinal function compared to the three hole method.Patients also have higher scores of satisfaction with incision scars,and the overall incidence of postoperative complications is also lower.

Objective:To investigate the effects of unilateral ureteral obstruction on renal pelvic peristalsis and pacemaker cells in neonatal rats.Methods:An animal experimental study.Thirty-six 2-day-old newborn SD rats were randomly divided into the partial unilateral ureteral obstruction (PUUO) group, complete unilateral ureteral obstruction (CUUO) group, and sham operation group, with 12 rats in each group.One week after surgery, all rats were subjected to renal pelvic pressure (RPP) measurement by puncture.After measurement, the rats were euthanized, and their left renal pelvis and ureter were removed and fixed for histological examination.Parameters such as RPP, peristaltic wave frequency and amplitude at different perfusion speeds were recorded and compared, and the changes in pacemaker cells (atypical smooth muscle cells and Cajal-like interstitial cells) were also compared.The independent samples t-test was used for comparison between 2 groups, and the one-way ANOVA of variance was used for comparison among 3 groups. Results:In the sham operation group, the RPP increased gradually with the increase of perfusion speed; the frequency of peristaltic waves rose rapidly and then dropped after reaching the highest level with the increase of perfusion speed; similarly, the amplitude of peristaltic waves first increased and then decreased as the perfusion speed increased.In the PUUO group, the RPP increased rapidly with the increase of perfusion speed, higher than that in the sham operation group; the frequency of peristaltic waves was higher than that in the sham operation group, and it was relatively constant under the perfusion speed of 40 mL/h, but when the perfusion speed increased again, the frequency began to decline; the amplitude of peristaltic waves increased quickly and then declined at a faster rate than the sham operation group with the increase of perfusion speed.In the CUUO group, the basic RPP was 12 cmH 2O(1 cmH 2O=0.098 kPa); at the perfusion speed of 5 mL/h, the RPP rose gradually, and no plateau appeared; when the RPP reached 73 cmH 2O, the perfusate retrograded from the side of the puncture needle, then the RPP slightly decreased and then balanced, and no regular peristaltic waves were observed in the renal pelvis throughout the whole perfusion process.Immunofluorescence staining analysis showed the pacemaker cells were all located in the smooth muscle of the renal pelvic wall.The sham operation group had the highest positive rate, followed by the PUUO group and then the CUUO group. Conclusions:Ureteral obstruction has a significant impact on the peristalsis of the renal pelvis, and its impact on the peristaltic wave frequency and amplitude and RPP can be predicted.The reduction of pacemaker cells in the renal pelvis may be involved in the changes of renal pelvic peristalsis caused by ureteral obstruction, but further research is needed on how pacemaker cells regulate the peristalsis of the renal pelvis and ureter.
