Objective To discuss the safety and efficacy of gasless laparoscopy in gynecological surgery.Methods A total of 58 patients who received gasless laparoscopic surgery from October 2006 to December 2007 were enrolled in this study.Among the patients,31 underwent ovarian cystectomy,23 received myomectomy,3 laparoscopic-assisted transvaginal hysterectomy(LAVH),and 1 salpingectomy(because of ectopic pregnancy).One trocar was used in 13 cases(ovarian cystectomy in 11 and myomectomy in 2) with the assistance of hysteroscopic resectoscopy,two trocars were employed in 27 cases(ovarian cystectomy in 11 and myomectomy in 16),and three trocars in 18 cases(ovarian cystectomy in 9,myomectomy in 5,LAVH in 3,and salpingectomy in 1).The instruments employed in this study were purchased from Daoke Co.Results All of the 58 surgeries were successfully completed.In the patients received ovarian cystectomy,the mean intraoperative blood loss was(46.8?10.1) ml(ranged from 10 to 200 ml),and the mean operation time was(66.3?6.7) min(30-150).While in the patients underwent myomectomy,the mean intraoperative blood loss was(94.3?8.2) ml(10-400),and the mean operation time was(104.3?6.7) min(60-180).For the 3 cases of LAVH,intraoperative blood loss was 100,200,and 150 ml;and operation time was 255,240,and 135 min,respectively.The salpingectomy was finished within 30 min.None of the 58 patients developed complications during and after the operations.They were discharged from the hospital in(7.9?1.6) days,and were followed up for 3 to 6 months,during which no complications occurred.Conclusions Gasless laparoscopic surgery is safe,effective,and minimally invasive for gynecological diseases.The procedure can be used for eldly patients and those who cannot tolerate general anesthesia due to cardiovascular diseases.

Objective To evaluate the value of gasless laparoscopic myomectomy(GLM)using a subcutaneous abdominal wall lifting system for leiomyomas.Methods The surgical outcomes,including operation time,intraoperative blood loss,recovery time of gastrointestinal function,hospital stay,complications,and cost of GLM using a subcutaneous abdominal wall lifting system(GLM group)and laparoscopic myomectomy with pneumoperitoneum(LM group)were compared.Results No intra-or post-operative complications occurred in both of the groups.No significant difference was found in the operation time and blood loss between the GLM and LM groups [(99.2?35.4)min vs.(102.7?28.8)min,t=-0.411,P=0.682;(77.0?48.3)ml vs.(89.6?53.8)ml,t=-0.940,P=0.351].While the GLM group had significantly shorter recovery time of gastrointestinal function and hospital stay [(1.8?0.5)d vs.(2.1?0.3)d,Mann-Whitney U=304.000,P=0.013;and(8.7?2.9)d vs.(10.3?3.1)d,t=-2.031,P=0.047],and lower cost [(6372.8?784.7)yuan vs.(7984.6?1048.7)yuan,t=-6.657,P=0.000].Conclusions Since GLM does no results in longer operation time and more blood loss than LM with pneumoperitoneum,it is suitable for large leiomyoma.The patients have quicker recovery,shorter hospital stay,and lower hospital cost after GLM.

To study the kinetics in vivo of a Hantaan virus DNA vaccine, we constructed a fusion DNA vaccine,pEGFP/S, by cloning the S segment of Hantavirus into the vector, pEGFP-C1, which encodes Green fluorescent protein EGFP. In this report, we provide evidence that pEGFP/S was distributed and persistently expressed for more than 60 days in several organs after inoculation. Our findings suggest that the persistent immune responses induced by a Hantaan virus DNA vaccine are likely due to the plasmid pEGFP/S deposited in vivo, which acts as a booster immunization.

Objective: To explore the improvement effect of hypnotherapy on dysmenorrhea symptoms of female college students with primary dysmenorrhea, in order to provide reference for the intervention and treatment of female college students with primary dysmenorrhea. Methods: From Septerber to December 2021, 90 female college students diagnosed with primary dysmenorrhea in Qinzhou First People s Hospital were randomly divided into hypnotic suggestion group( n =30), hypnotic relaxation group ( n =30) and control group( n =30). The 10 session hypnotic suggestion and 10 session hypnotic relaxation interventions were carried out while the control group received no intervention. Participants in the three groups were assessed by using the Visual Analogue Scale(VAS), Beck Depression Inventory Ⅱ(BDI Ⅱ), State Anxiety Inventory(SAI), Questionnaire of Quality of Life of College Students(QOLCS), Cox Dysmenorrhea Symptom Scale (CMSS) before and after intervention. Results: After intervention, the VAS, BDI Ⅱ and SAI scores of the hypnotic suggestion group and the hypnotic relaxation group significantly decreased compared to those before the intervention( t =7.04, 13.32, 3.58, 2.15, 2.52, 2.01, P <0.05). There were statistically significant differences in VAS, BDI Ⅱ and SAI scores among the three groups( F =24.71, 29.57, 6.60, P <0.01). After intervention, the QOLCS total score, physical, psychological and behavioral dimension scores in the hypnotic suggestion group and the hypnotic relaxation group significantly improved( t =-4.61, -3.36, -3.12, -2.81, -2.71, -2.19, -2.69, -2.28, P <0.05). There were statistically significant differences in QOLCS total score, physical, psychological, behavioral, environmental, and social support dimension scores among the three groups( F =10.36, 4.14, 5.14，4.81, 7.07, 5.53, P <0.05). After the intervention, the CMSS dysmenorrhea severity and dysmenorrhea duration scores in the hypnotic suggestion group and the hypnotic relaxation group were significantly lower than those before the intervention( t =5.66, 4.70, 3.09, 2.21, P <0.05). There were significant differences in CMSS dysmenorrhea severity and dysmenorrhea duration scores among the three groups( F=15.33, 12.33, P <0.05). Conclusion Hypnotherapy can help relieve pain of female college students with primary dysmenorrhea，improve depression and anxiety.

The pathogenesis of cerebral malaria is biologically complex and involves multi-factorial mechanisms such as microvascular congestion, immunopathology by the pro-inflammatory cytokine and endothelial dysfunction. Recent data have suggested that a pleiotropic T-cell immunomodulatory protein (TIP) could effectively mediate inflammatory cytokines of mammalian immune response against acute graft-versus-host disease in animal models. In this study, we identified a conserved homologue of TIP in Plasmodium berghei (PbTIP) as a membrane protein in Plasmodium asexual stage. Compared with PBS control group, the pathology of experimental cerebral malaria (ECM) in rPbTIP intravenous injection (i.v.) group was alleviated by the downregulation of pro-inflammatory responses, and rPbTIP i.v. group elicited an expansion of regulatory T-cell response. Therefore, rPbTIP i.v. group displayed less severe brain pathology and feverish mice in rPbTIP i.v. group died from ECM. This study suggested that PbTIP may be a novel promising target to alleviate the severity of ECM.
