Objective To provide ideal endometriosis animal models for research new treatment methods. Methods 64 Sexual mature without pregnant SD rats who has regular oestrous cycle were underwent operation that autologous endometrium were transplanted to peritoneum and subcutaneous with lancet gently cut tissue of where to transplant in the rut, and compared the model of peritoneum and subcutaneous after 4 weeks.Results The general success rate of autologous endometrium transplantation in rat estrus was 93.3%,and the peritoneum transplantation success rate was 51.7%, subcutaneous was 88.3%, the difference of the two place transplantation has statistical significance. Compare the two parts of volume of endometriosis,there was no statistically significant difference.Conclusion Using the lancet to establish the endometriosis model has a high success rate, and subcutaneous model is better than peritoneum.

ObjectiveTo observe the clinical effect of Kangxiuke apozem in the treatment of severe bum shock.Methods40 patients of severe burn shock were randomly divided into a treatment group and a control group,with 20 patients in each group.All the patients were treated by the same route of counter-shock therapy,and the treatment group was additionally given Kangxiuke apozem (nasal feeding,qd,150 ml/d).Level of blood lactic acid,heart rate and urinary volume were evaluated by time.Main shock symptoms,including restlessness,hydrodipsia,perspiration and coldness,were observed.ResultsThe treatment group was significantly superior to the control group in the amelioration of blood lactic acid,heart rate and urinary volume ( t =10.485、3.219、7.429,P＜ 0.01 ).The symptomatic extinction of restlessness,hydrodipsia,perspiration and coldness in the extremities in the treatment group were significantly superior to those in the control group (x2=10.16、7.37、5.63、4.29,P＜0.05).ConclusionAt the same time of routine counter-shock therapy,thereby prompt burn patients to smoothly go through shock period and decreas late complications.

Objective To explore relations between pseudo vascular invasion (PVI) and laparoscopic operation in patients with stage Ⅰa endometrial carcinoma. Methods Details of stage Ⅰa endometrial carcinoma patients′ clinical information and pathological sections who received operation treatment between January 2008 and October 2015 were obtained from the Dalian Maternal and Child Health Hospital. There were 515 cases entrolled into this study, including 332 (64.5%) cases performed surgery by laparoscopy and 183 (35.5%) cases undergone abdominal surgery. The vascular invasion rate and the microscopic manifestations of PVI in two groups were retrospectively compared and analyzed. The follow-up period ended February 2017, the adjuvant treatment and prognosis of patients with lympho-vascular space invasion (LVSI) and PVI were analysed. Results (1) Seventy-five of 515 cases with stage Ⅰa endometrial carcinoma, there were seven-five cases found with tumor cells in lympho-vascular space, including 52 cases of LVSI and 25 cases of PVI (2 cases of both). The incidence of cancer emboli in lympho-vascular space and LVSI in laparoscopic group and laparotomy group were respectively 15.4%(51/332) vs 13.1%(24/183) and 9.6%(32/332) vs 10.9%(20/183), there were no significant differences (all P>0.05). But the rate of PVI between the two group was significantly different [6.3% (21/332) vs 2.2%(4/183), P=0.036], laparoscopic group was higher than that in laparotomy group. (2) Of 332 cases in laparoscopic group, 21 cases was found PVI, containing 8 cases showed tumor tissue with mesenchyme or papillary structures located in large thick wall vessels of the outer lateral myometrium, 13 cases showed the tumor tissue was away from the vessel wall. Among 183 cases in laparotomy group, 3 cases with PVI which the tumor tissue was away from the vessel wall, and 1 with interstitial tissue. (3) During the follow-up period, 7 of 75 cases (both LVSI and PVI) were lost, and 66 cases were relapse-free survival, 2 cases recurred at fifth months and died respectively at 7, 20 months after the operation. This 2 cases were both PVI of laparoscopic group, and the pathological type was endometrioid adenocarcinoma grade 3, and adjuvant treatment was not accepted after the operation. The relapse-free survival with LVSI was 49 months and 46 months for cases with PVI. Conclusions Laparoscopic operation could increase PVI in patients with stageⅠa endometrial carcinoma, while does not increase LVSI. It is not yet possible to demonstrate that PVI affects the prognosis of patients.

Objective:To investigate the clinical efficacy of full-endoscopic technique through the posterior cervical Delta large portal for the treatment of cervical spondylotic myelopathy and radiculopathy.Methods:The clinical data were analyzed retrospectively of the 15 patients who had been treated for cervical spondylotic myelopathy or radiculopathy at Orthopedics Department, Jiaxing Xiuzhou District People's Hospital from January 2020 to June 2021. There were 6 males and 9 females, aged from 54 to 76 years (average, 66.2 years). Responsible levels: 3 cases of C3, 4, 4 cases of C4, 5, 7 cases of C5, 6 and 1 case of C6, 7. They were all treated by full-endoscopic technique through the posterior cervical Delta large portal. The therapeutic efficacy was assessed by comparing the neck disability indexes (NDI) and Japanese Orthopaedic Association (JOA) cervical scores at preoperation, 1 and 3 months post-operation, and the last follow-up, and the modified MacNab scores at the last follow-up. The operative effects on cervical curvature and segmental stability were assessed by comparing the C2-7 cobb angles and operative ranges of motion (ROM) at preoperation, 1 and 3 months postoperation, and the last follow-up.Results:All cases completed their operation successfully. The operation time ranged from 56 to 82 min (average, 65.7 min), and the intraoperative blood loss from 10 to 30 mL (average, 20.7 mL). Tissue infection, intraspinal infection, dural tear, nerve root injury or perioperative anesthesia-related complications occurred in none of the patients. All patients were followed up for 6 to 18 months (average 10.8 months). The NDIs at 1 and 3 months post-operation, and the last follow-up (18.54%±3.06%, 14.96%±2.33%, and 12.89%±2.33%) were significantly lower than that before operation (34.19%±3.83%), and those at 3 months postoperation and the last follow-up significantly lower than that at 1 month postoperation ( P<0.05), but there was no significant difference between 3 months postoperation and the last follow-up in NDI ( P>0.05). The JOA scores at 1 and 3 months postoperation, and the last follow-up [(12.28±1.65), (13.30±1.57) and (13.54±1.41) points] were significantly higher than the preoperative value [(9.25±1.49) points] ( P<0.05), but there was no such a significant difference between postoperative time points ( P>0.05). Comparisons between preoperation, 1 and 3 months postoperation, and the last follow-up showed no significant difference in the C2-7 cobb angle or operative ROM ( P>0.05). The modified MacNab scores at the last follow-up resulted in 9 excellent, 5 good and 1 fair cases. Conclusion:In the treatment of cervical spondylotic myelopathy and radiculopathy, the full-endoscopic technique through the posterior cervical Delta large portal shows the advantages of limited invasion and complications, rapid recovery after operation, and little impact on the cervical curvature and segmental stability.

[Abstract] Objective: To investigate the short-term clinical efficacy and safety of intraperitoneal perfusion of natural killer (NK) cells in the treatment of ovarian cancer with ascites. Methods: The clinical data of 15 ovarian cancer patients with ascites effusion, who received NK cell perfusion in the Qinhuai Medical District of the General Hospital of Eastern Theater Command from November 2016 to January 2019, were analyzed. The peripheral blood was collected to isolate the peripheral blood mononuclear cells, and to further obtain the NK cells after culture. NK cell suspension was intraperitoneally perfused into the abdominal cavity (no less than 2×109 cells/ time). The volume of peritoneal effusion, the level of serum tumor marker CA-125, the level of serum cytokines IL-2, INF-γ and TNF-α as well as the changes in peripheral blood lymphocyte subsets were detected before and after the treatment; Moreover, the clinical efficacy and adverse reactions were observed. Results: The effective rate of intraperitoneal perfusion of NK cells was 66.7%, and there were no obvious treatment-related adverse reactions. Compared with before treatment, the serum tumor marker CA-125 level significantly decreased after treatment (P<0.05), and the levels of IL-15, IFN-γ and TNF-α increased significantly (P<0.05 or P<0.01), while there was no significant changes in peripheral blood lymphocyte subsets (all P>0.05). Conclusion: Intraperitoneal infusion of NK cells in the treatment of ovarian cancer associated peritoneal effusion has a good short-term clinical efficacy with little adverse reactions, which is a promising method for the treatment of cancerous peritoneal effusion.
