Objective:Laparoscopic surgery for cervical cancer has the advantages of little blood loss and rapid recovery,but its therapeutic effect is still controversial.This study aims to analyze the surgical procedure and clinical efficacy of tumor-free laparoscopic radical hysterectomy without a uterine manipulator for early-stage cervical cancer,and to explore the indications of laparoscopic surgery for cervical cancer. Methods:This study was a retrospective study.The data of patients who underwent radical hysterectomy for early-stage cervical cancer admitted to Hunan Provincial Maternal and Child Health Care Hospital from July 2019 to December 2021 were collected.According to 2018 the International Federation of Gynecology and Obstetrics(FIGO)clinical staging,all patients were in IA1 with lymphovascular invasion,IA2,and IB1 stage.Among them,45 patients underwent tumor-free laparoscopic radical hysterectomy without a uterine manipulator(laparoscopy group)and 16 patients underwent open surgery(open surgery group).Patients were followed up for 12-41 months.The differences between the 2 groups in terms of operative time,bleeding volume,extent of surgical resection,surgical complications,and prognosis were compared and analyzed. Results:Compared to the open surgery group,the laparoscopy group had significantly shorter operation time and less intraoperative blood loss(both P＜0.001).There were no significant differences between the 2 groups in terms of the length of excised uterosacral ligaments,cardinal ligaments,vagina,and the number of excised lymph nodes(all P＞0.05).The incidence of postoperative complications did not differ significantly between the groups(P＞0.05).No death or recurrence occurred in the 2 groups during the follow-up period.The overall survival rate and disease-free survival rate were both 100%. Conclusion:For early-stage cervical cancer with a diameter≤2 cm,tumor-free laparoscopic radical hysterectomy without a uterine manipulator is safe and feasible,and the short-term outcomes is no less than that of open surgery.

Objective To investigate the clinical efficacy of Dahuang Xiaozhi Suppository in treating chronic abacterial prostatitis/chronic pelvic pain syndrome (CABP/CPPS) of moist heat and blood stasis syndrome. Methods Two hundred patients of CABP/CPPS were randomly divided into control group and observation group, 100 cases in each group. 2 groups were disabled anti-infective meidicne and other preparations, and received diet and life intervention. The control group received the treatment of Qianliean Suppository, and the observation group received the treatment of Dahuang Xiaozhi Suppository, one capsule each time, once a day, into the anus depth of about 3–4 cm. Ten days were a treatment course with two day interval between each course of treatment. The treatment lasted for three courses. The clinical efficacy of the two groups was observed and compared. The indexes including the scores of NIH-CPSI, leukocyte count and lecithin corpuscles in prostatic fluid, and urinary flow rate were evaluated. Results The total effective rate was 100% (100/100) in the observation group and 78% (78/100) in the control group, and the observation group was much higher than control group (P<0.05). The scores of NIH-CPSI and leukocyte count in both groups were significantly lower after treatment (P<0.01), and those in observation group weresignificantly lower than those in control group (P<0.01). The cases with lecithin corpuscles++++in both groups were significantly more after treatment (P<0.01), and those in observation group were significantly more than those in control group (P<0.01). The peak flow rate and mean flow rate in both groups were higher after treatment (P<0.01), and it was higher in observation group (P<0.01). Conclusion The efficacy of Dahuang Xiaozhi Suppository in treating CABP/CPPS of moist heat and blood stasis syndrome is remarkable, and it is better than Qianliean Suppository.

Objective To assess the mid-term and long-term efficacy of the permanent inferior vena cava filter in the treatment of deep vein thrombosis of lower limb and discuss the clinical significance of inferior vena cava filter.Methods Retrospectively analyze on the 86 cases with deep vein thrombosis of lower limb (41 males and 45 females,aged 50 to 94 years,mean age was 71.8 years) treated with implantation of permanent inferior vena cava filter in inferior vena cava from Janunary 2010 to October 2015.In these patients,there were 51 cases with embolism in the left leg,25 cases in the right leg,10 cases in both legs and 6 cases were accompanied with pulmonary embolism.The cases without contraindication underwent catheter directed thrombolysis and even percutaneous transluminal angioplasty or stents subsequently if necessary after inferior vena cava filter implantation.All the cases with no contraindication were treated with anticoagulant therapy.Results All the 86 patients were implanted inferior vena cava filter (B.Braun Vena Tech LP 76 and Cordis TrapEase 10)successfully.Sisty-five cases were underwent inferior wena cava filter implantation only,while 21 cases were treated with inferior vena cava filter implantation and catheter directed thrombolysis or even percutaneous transluminal angioplasty and stents.During the follow-up period(12 to 81 months,mean time was 51 months),27 patients died dueing to malignant tumor(17 cases) and other diseases (10 cases) rather than complications caused by inferior vena cava filter.Three patients had recurrence of deep vein thrombosis and 2 patients suffered from the thrombosis induced by stenosis of stents.Inferior vena cava filter appered tilted with angle less than 15 degrees in 6 cases.Three cases suffered from new thrombosis below the filter and 2 cases complained of the filter migration.No case was found with fracture of filter,perforation of the inferior vena cava,bleeding or pulmonary embolism(new onset or recurrent).Conclusions Application of permanent inferior vena cava filter may cause complications,though it is an effective approach to prevent pulmonary embolism in patients with deep vein thrombosis of lower limb.However,permanent inferior vena cava filter may be fit for patients with old age,incurable cancer or limited expected life.

Objective To evaluate left ventriclular systolic function in patients with obstructive hypertrophic cardiomyopathy (HOCM) after modified Morrow surgery using two-dimensional speckle tracking imaging (2D-STI).Methods Twenty three HOCM patients were recruited in this study.Echocardiographic data from HOCM patients during pre-operation,1-month and 3-month post-operation were analyzed by Qlab software to compare the variation in systolic function indicators 1-month and 3-month post-operation including global and 16 segmental longitudinal strain,circumferential strain and conventional echocardiographic parameters of left ventricle.Results Compared with preoperative data of HOCM patients,postoperative LVOT diameter and pressure gradient,left atrial diameter and volume index were significantly decreased(P<0.05),but there was no significant difference in left ventricular ejection fraction(P<0.05).Compared with the preoperative case,global and segmental longitudinal strain showed significant reduction after 1 week and gradually recovered after 3 months,without significant variation.The longitudinal strain of the anteroseptum reduced significantly and the longitudinal strain of the free wall increased after 3 months,however,the circumferential strain reduced significantly.The circumferential strain of basal and middle segment after 3 months had improved significantly than those of postoperative 1 week.The circumferential strain of surgical site is no obvious change and the strain of free wall was improved after 3 months.Conclusions 2D-STI can effectively evaluate global and regional systolic function of left ventricle for HOCM patients after modified Morrow surgery.

Objective To evaluate the relationship between intraplaque hemorrhage of cerebral arteries and acute cerebral infarcts. Methods 35 patients with severe stenosis in M1 segment of middle cerebral arteries (MCA)were included in this study.Intracranial TOF MRA (time of flight MR angiography)was performed to detect the stenosis in MCA,and DWI (diffusion weighted imaging) was performed to detect cerebral acute infarcts.T1 MPRAGE sequence was positioned on the stenosis in M1 segment of MCA,and intraplaque hemorrhage was determined according to high signal on T1 MRRAGE images.35 patients were divided into two groups:one group with intraplaque hemorrhage and the other group without intraplaque hemorrhage.Whether there was significant differ-ence in the incidences of acute cerebral infarcts between the two groups were determined byχ2 test.Results Intraplaque hemorrhage was detected in 1 5 patients,in which 12 patients had acute cerebral infarcts.There were no intraplaque hemorrhage in 20 patients,in which 9 patients had acute cerebral infarcts.There was significant difference in the incidences of acute cerebral infarcts between the two groups (P =0.046 <0.05).Conclusion There is a higher incidence of acute cerebral infarcts in patients with intraplaque hem-orrhage than those without intraplaque hemorrhage.Intraplaque hemorrhage in severe stenosis of cerebral arteries is a high-risk indi-cation for acute cerebral infarction.

Objective In this study,folic acid(FA) was tested for antiteratogenic effects on Tetrachlorodibenzo-p-dioxin(TCDD)-induced cleft palate in fetal mice.Methods In the present study,pregnant mice were dosed with TCDD 24 μg/kg and with or without FA 5 mg/kg body weight on gestation day 10.Control group mice received sesame oil 50 ml/kg body weight on gestation day(GD)10.The mice were sacrificed on GD12.5,GD13.5,GD14.5,GD15.5 and GD16.5.From each pregnant mouse on GD16.5,embryos were obtained to examine under a dissecting microscope,and routine histology was performed for detection and classification of palatal clefts.The fetuses were prepared for histologic examination,scanning electron microscope and TdT-mediated X-dUTP nick and labeling(TUNEL).On GD12.5,GD13.5,GD14.5 and GD15.5.Meanwhile,real-time(RT)-PCR was employed to detect the mRNA expression levels about arylhydrocarbon receptor(AHR) and transforming growth factor(TGF)β3 in this animal model.Results Total frequencies of clefts were 70.2％ in TCDD group(group B) and 66.3％ in TCDD + FA group(group C) in relation to control fetuses(group A).Filopodia disappeared completely at the medial edge epithelia surface on GD15.5(group A),GD12.5(group B) and GD14.5(group C).the RT-PCR results showed that TGF-β3 expression was down-regulated on GD13.5 and GD14.5 compared to the control.Conclusions It is found that folic acid has no protects agaist 2.3.7.8-TCDD-indued cleft palate in the experiment.Meanwhile,TCDD repressed the TGF-β3 expression during the palatal development.Anormal apoptosis was induced by 2,3,7,8-TCDD at the medial edge epithelia(MEE) during the early development stage.

OBJECTIVE: To analyze the clinical pathologic characteristics of cervical intraepithelial neoplasia grade III (CINIII ) and to explore optimal surgery for CINIII patients. METHODS: The clinical pathologic characteristics, surgical treatments, prognosis and history of 383 CINIII patients, who hospitalized from August 2005 to December 2010, were reviewed and analyzed. Among the patients, 213 (55.6%) received cold-knife conization surgery and 170 (44.4%) received ordinary electric knife conization surgery. RESULTS: There was no significant statistic difference between cold-knife conization group and ordinary electric-knife conization group on the level of clearance of the pathologic tissues and the cervical cone diameter and cone high. Intraoperative blood loss was (13.1±5.2) mL and (25.5±17.2) mL. Bleeding of electric knife conization group, compared with that of the cold knife conization group, decreased by nearly 50%. The difference between the 2 groups was significant (P<0.01). Pathological examination after conization operation indicated that 350 out of the 383 patients didn't show pathological upgrade while 33 patients showed pathological development, among which 21 were diagnosed with invasive cervical cancer at Ia1 clincal stage, 7 atIa2 clincal stage and 5 atIb1 clincal stage. In 3 cases (14.3%) Ia1 cervical cancer patients, fertility requirements and negative margins with cervical conization were closely followed up, and one patient (4.8%) with positive margin and fertility requirements had re-conecut. The remaining 17 (80.9%) had resected the uterus outside the fascia (or plus attachments) . All the 12 patients with invasive cervical cancer at Ia2 orIb1 clinical stage received radical hysterectomy. No tumor recurrence was observed in the 383 patients. CONCLUSION Treatment optimazation of CINIII patients should be based on clinical pathological diagnosis and individual requirements. Both cervical conization surgery and total hysterectomy have been proved safe and practical for CINIII patients.
