Objective To investigate the efficacy of laparoscopic C-type radical hysterectomy through deep uterine vein approach for the treatment of cervical cancer.Methods From January 2021 to December 2022,58 cases of cervical cancer were treated with deep uterine vein approach laparoscopic C-type radical hysterectomy in our hospital.After establishing the operation channel,the ureter was identified in the posterior lobe of the broad ligament,and the uterine artery was exposed after separating the ureter.The connective tissue was separated along the dorsal side of the uterine artery to gradually expose the deep uterine vein.The parametrial lymph nodes surrounding the deep uterine vein were resected and sent to pathology alone.The deep uterine vein was continuously tracked towards the bladder,and its branches were freed.The deep uterine vein and its tributaries were double clipped by vascular clamp.Results The operation time was(307.2±54.1)min,the median bleeding volume was 50(20,100)ml,the lymph node dissection number was(26.3±6.9),the indwelling catheter time was(20.6±4.7)d,the time to removal of abdominal drainage tube was(9.4±4.1)d,the anal exhaust time was(36.7±4.1)h,the antibiotics use time was(9.2±4.2)d,and the hospital stay was(13.4±2.6)d.The postoperative complication rate was 3.4%(2/58),and the postoperative pathological staging upgrade rate was 22.4%(13/58).The postoperative European Organization of Research and Treatment of Cancer(EORTC)Quality of Life Questionnaire-Core 30(QLQ-C30)score was significantly higher than before surgery[(78.6±10.7)points vs.(47.1±7.6)points,t = 17.177,P = 0.000].All the 58 cases were followed up for 4-25 months(mean,13.5±6.2 months),with no recurrence.Conclusion Laparoscopic C-type radical hysterectomy through deep uterine vein approach is effective,safe,and reliable.

ObjectiveTo investigate the effects of different acupuncture schemes on behaviors, neurotransmitters and inflammation-related factors in post-stroke depressed (PSD) rats. MethodsA total of 72 healthy male Sprague-Dawley rats were randomly divided into normal group, model group, drug control group, scalp acupuncture group, abdominal acupuncture group and combined acupuncture group, 12 rats in each group. The PSD model was prepared using a combination of middle cerebral artery occlusion and chronic unpredictable mild stimulation (CUMS) for the model and each intervention groups. The drug control group was administered fluoxetine, the scalp acupuncture group accepted acupuncture at Baihui (DU 20) and Yintang (EX-HN3), while the abdominal acupuncture group at Zhongwan (RN 12) and Guanyuan (RN 4), the combined acupuncture group at all the four acupoints, for 21 days. They were assessed with Longa neurological function score, body mass, open-field test and sugar-water preference test on the 0 (before modeling), the seventh (before CUMS), the 14th (before treatment) and the 35th day (after treatment). The levels of 5-hydroxytryptamine (5-HT), dopamine (DA), norepinephrine (NE), interferon-γ (INF-γ), tumor necrosis factor⁃α (TNF⁃α) and macrophage migration inhibitory factor (MIF) in the serum were determined with ELISA on the 35th day. Results The neurological function score was lower in the drug control group and the combined acupuncture group thanin the model group (P < 0.01) on the 35th day; while the body mass was higher in the drug control group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.01); and the number of horizontal span frames, the number of uprightness and the sugar water consumption were higher in the drug control group, the scalp acupuncture group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.05). There was no significant difference among the four intervention groups (P > 0.05). The levels of 5-HT, DA and NE were higher in the four intervention groups than in the model group (P < 0.01), and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01). 5-HT level was higher in the combined acupuncture group than in the scalp acupuncture group and the abdominal acupuncture group, and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01); the levels of DA and NE was higher in the combined acupuncture group than in the abdominal acupuncture group (P < 0.01). ConclusionThe combination of scalp acupuncture and abdominal acupuncture can improve behavior, neurotransmitters and inflammatory factors of PSD rats, like fluoxetine. Scalp or abdominal acupuncture alone is still effecive, and can be used secondarily.

Objective To observe the effect of Bushen Gutai mixture on uterine blood supply of rat model of abortion induced by hydroxyurea tablets combined with mifepristone through PKA-CREB signal pathway and its mechanism of calming fetus.Methods 60 pregnant rats of SPF grade SD rats were prepared by closing cages at 2∶1.According to the order of pregnancy,60 pregnant rats were randomly divided into 6 groups with 10 rats in each group:Bushen Gutai mixture group(low,middle and high dose),normal pregnancy group,model group and Di qu progesterone group.On the 1st to 9th day of pregnancy,except the normal group,the pregnant rats in each group were gavaged with hydroxyurea tablets at 5∶00 pm every day(450 mg·kg-1),and at 10∶00 am on the 10th day of pregnancy.Mifepristone tablets were given by intragastric administration(4.0 mg·kg-1).At 9∶00 am every day from the 1st to 9th day of pregnancy,Bushen Gutai mixture was given to the low,middle and high dose groups(0.5,1.0,2.0 g·kg-1),didrone group(3.02 mg·kg-1),model group and normal pregnancy group with 0.9%normal saline.24 hours after the last administration of pentobarbital sodium(50 mg kg-1),all pregnant rats were killed by intraperitoneal injection of pentobarbital sodium,and the uterine decidual tissue of pregnant rats was bluntly isolated in sterile environment.Hematoxylin-eosin(HE)staining was used to observe the lumen diameter and wall thickness of spiral artery in uterine decidual tissue.Immunohistochemical staining(IHC)was used to detect the expression of vascular endothelial growth factor(VEGF)in decidual tissues.Western blot was used to detect the protein expression of phosphorylated protein kinase A,protein kinase A,phosphorylated cyclic adenosine monophosphate response element binding protein,Cyclic Adenosine monophosphate response element binding protein and aquaporin 5 in the decidua of pregnant rats.The apoptosis of decidual cells was detected by in situ end labeling(TUNEL)of DNA fragmentation.Results Compared with the model group,the wall thickness of spiral artery was higher than that in other groups(P<0.05),the lumen diameter was lower than that in other groups(P<0.05)and the expression of VEGF protein was lower than that of other groups(P<0.01).Compared with the model group,the apoptosis level of decidual cells in uterine decidua of abortive rats in high,middle and low dose groups of Bushen Gutai mixture and diqu progesterone group decreased in varying degrees.Bushen Gutai mixture can up-regulate the levels of p-PKA/PKA and p-CREB/CREB in uterine decidua(P<0.01)and promote the expression of AQP5 protein in uterine decidua of abortion rats(P<0.01).Conclusion Bushen Gutai mixture can improve uterine blood supply of aborted rats by activating PKA and CREB phosphorylation,up-regulating AQP5 expression,promoting physiological recasting of spiral artery and high expression of Vascular endothelial growth factor.

Objective Although the correlation between high risk human papilloma virus (hrHPV) infection and cervical cancer ( CC ) or cervical intraepithelial neoplasia ( CIN ) is well known , vaginal cancer ( VC ) or vaginal intraepithelial neoplasia ( VAIN) also caused by hrHPV has not received enough attention .This article aims to explore the clinical characteristics of VC or VAIN after operations of CC or CIN in order to provide evidence for the treatment of these diseases . Methods The clinical charac-teristics and treatment of 15 cases with VC or VAIN after operations of CC or CIN were reviewed from Jan 2010 to May 2013 in our hos-pital. Results The mean age was (53.6 ±10.82) years, ranged from 39 to 73 years.The duration from the first operation to devel-oped VAIN or VC was (25.07 ±18.31) months, ranged from 1 to 60 months.There are 4 cases developed VC, 4 cases VAINⅢand 2 cases VINⅡfrom 10 CC patients;and 3 cases developed VC , 2 cases VAINⅢfrom 5 CINⅢpatients.hrHPV test were positive in all 15 patients.Treatment in these series were performed including total vaginectomy in 8 patients (3 VC, 4 VAINⅢ and 1 VAINⅡpatients), pelvic lymphonectomy in 1;upper vaginectomy in 2 patients (1 VC, 1 VAINⅢ), radiation or chemo-radiation therapy in 3 (3 VC), interferon muscle injection combined with topical application of estrogen and acyclovir gel in 2 (1 VC, 1 VAINⅡ). Conclusion Careful follow-up after CC or CIN operations are very important because continued hrHPV infection may result VC and VAIN lesions.Vaginectomy may be the best therapy .Interferon muscle injection combined with topical application of estrogen and acyclovir gel are also alternatively therapy , especially for hard to operate patients . Radiation therapy seems to be not very adaptable for VAIN patients .
