RESUMO
Energy devices have been widely used in gynecological surgeries. From the overall development trend, energy devices improve the efficiency of surgery. The continuous updating and upgrading of energy devices also reduces surgical complications and improves the safety of surgery. The injury caused by energy devices is not only related to the complexity of the operation or the disease itself, but also closely related to whether the operator can reasonably choose and master the use of energy instruments, as well as the surgical skills and experience of the operator. Surgeons should establish the concept of " prevention is better than remedy" when using energy instruments. We should take the initiative to learn and master the working principle of different energy devices, understand the design characteristics of each product and improve the skills of device use, so as to minimize the complications caused by various energy instruments and bring real benefits to doctors and patients.
RESUMO
Objective:To evaluate the clinical effectiveness and safety of Jiuwei-Zhuhuang San plus amoxilcillin sodium and sulbactam sodium in the treatment of bacterial pneumonia in children. Methods:A total of 120 patients with bacterial pneumonia in children from 1 year to 14 years old were randomly divided into the study group ( n=90) and the control group ( n=30) with ratio 3 to 1, the random sequence created by SAS software. Both groups were treated with amoxilcillin sodium for basic treatment, the observation group was treated with Jiuwei-Zhuhuang San. Both groups were treated for 1 week and followed up for 1 week. The cough frequency, clinical effective rate, symptoms and signs score, Traditonal Chinese medicine (TCM) pattern scores and adverse event rate were observed. Results:Eighteen cases were dropped and eliminated in the observation group, and 4 cases were dropped and eliminated in the control group, so 72 of observation group and 26 of control group were analyzed. After treatment, the clinical effective rate of the observation group was 27.8% (20/72), and the control group was 0% (0/26), where the difference was significant ( χ2=7.445, P=0.006). The difference of TCM syndrome score before and after treatment in the observation group (-16.8 ± 8.2 vs. -11.0 ± 5.8, t=-3.858) was lower than that of the control group ( P<0.01). There was significant difference between the two groups ( Z=-2.347, P= 0.019) in the TCM syndrome. The cough frequency of the observation group was 41.7% (30/72), and the control group was 26.9% (7/26). There wasn’t any significant differences in the cough frequency between two groups ( P>0.05). There was no statistical difference in symptoms and signs score or adverse event rate between two groups ( P>0.05). Conclusion:On the basis of amoxicillin sodium and sulbactam sodium, combined use of Jiuwei-Zhuhuang San can improve the clinical effectiveness of children with bacterial pneumonia.
RESUMO
Objective:To investigate the value of positron emission tomography/computed tomography (PET/CT) in diagnosis of retroperitoneal lymph node metastasis for early cervical cancer.Methods:Retrospectively analyze the preoperative PET/CT examination results and postoperative pathological results of patients with early cervical cancer who underwent surgical treatment from May 5, 2019 to August 31, 2020, and analyze the clinical characteristics, so as to explore the high risk factors of PET/CT in the diagnosis of retroperitoneal lymph node metastasis.Results:The accuracy, sensitivity, specificity and area under the curve (AUC) of PET/CT in the diagnosis of retroperitoneal lymph node metastasis were 75.2%, 60.0%, 81.3% and 0.707, respectively. Univariate analysis showed that 2009 International Federation of Gynecology and Obstetrics (FIGO) stage, tumor diameter >4 cm, lymphovascular space involvement (LVSI) positive, depth of invasion, high squamous cell carcinoma antigen (SCC-Ag) level and cytological grade were important factors for PET/CT in the diagnosis of retroperitoneal lymph node metastasis ( P<0.05); Multivariate analysis showed that tumor diameter >4 cm was an independent risk factor for PET/CT diagnosis of retroperitoneal lymph node metastasis ( P=0.015). Conclusions:PET/CT has a certain diagnostic value in the evaluation of retroperitoneal lymph node metastasis, but it can not fully reflect the facticity of lymph node metastasis; tumor diameter > 4cm is an independent risk factor for PET/CT in the diagnosis of retroperitoneal lymph node metastasis.
RESUMO
Objective To explore the outcomes of the oncology, the fertility and pregnancy on patients with early-stage cervical cancer after undergoing fertility-sparing treatments, and to investigate its value on clinical treatment. Methods A total of 29 patients with cervical cancer (stage Ⅰa2-Ⅰb1) who had undergone the fertility-sparing treatments in Renji Hospital, School of Medicine, Shanghai Jiaotong University from February 2010 to September 2015 were analyzed retrospectively. Surgical procedures included transvaginal cervical cold knife conization (CKC)+laparoscopic pelvic lymphadenectomy (PLD) or total laparoscopic uterine cervix extensive resection (RT; contains PLD); 48 patients with early cervical cancer under going laparoscopic uterine extensive resection (RH; contains PLD) by the same group of physicians in the same period were chosen as the control group. The perioperative related indicators, postoperative specimen examination, pregnancies after surgery and postoperative tumor follow-up results were retrospectively analyzed and compared between the two groups. Results (1) Among these 29 patients in the study group, 26 cases were underwent the fertility-sparing surgery quick frozen pathological examinations were positive in 3 cases, which underwent total laparoscopic RT eventually. (2) The perioperative related indicators: compared with the study group and the control group, the operation time [(182 ± 21), (147 ± 24) minutes, respectively] has significant difference (t=6.563, P0.05) in intra-operative blood loss [(102±26), (99±34) ml], postoperative aerofluxus time [(1.3±0.4), (1.1±0.9) days], the average length of hospital stay [(11.2 ± 2.1), (10.6 ± 3.5) days], rate of urine retention [10%(3/29), 10%(5/48)] and rate of postoperative infection [3%(1/29), 2%(1/48)]. (3)Postoperative specimen examination:compared with the study group and the control group, there were no significant difference (P>0.05) innumber of removed lymphatic nodes (23.4 ± 4.1, 22.8 ± 3.9), length of cardinal ligament [(2.9 ± 0.5), (3.0 ± 0.6) cm], lengthof uterosacral ligament [(2.6±0.7), (2.8±0.4) cm], length of removed vaginal [(3.4±0.3), (3.5±0.3) cm]. (4) Pregnancies after surgery and postoperative tumor follow-up results:in the study group, only 14 patients had fertility requirement after treatments. Pregnancies occurred in 5 women (5/14), which included1 case of full-term labor, 1 case of preterm labor, and 3 cases of spontaneous abortion. The Average follow-up time in postoperative patients of the study group and control group was 29.4, and 30.2 months respectively. In follow-up period, compare with study group and the control group, there was no significant difference (χ2=0.004, P>0.05) in the recurrence rate [4%(1/26), 4%(2/48)]. Conclusion Fertility-sparing surgery of early-stage cervical cancer is safe but the outcome of the fertility and pregnancy is still need toimprove.
RESUMO
ObjectiveTo discuss the clinical efficacy of low dose heparins and low molecular weight heparins (LMWHs) in the treatment of severe traumatic disseminated intravascular coagulation (DIC).MethodsA total of 77 trauma patients (APACHE Ⅱ score for 5-10) with secondary DIC in ICU were included and randomly assigned to three groups,ie,Group A (26 patients,subcutaneously injected with LMWHs at doses of 75-150 U · kg-1 · d-1,with the average incipient dose of 4 000 U/d),Group B (25 patients,subcutaneously injected with heparins at doses of 100-250 U · kg-1 · d-1,with the average incipient dose of 5000 U/d and control group (26 patients,supplemented with simple blood coagulation factor).The injection volume was adjusted according to the level of antithrombin Ⅲ ( ATⅢ ) in each group.Within 28 days in ICU,the three groups were compared in aspects of deaths,hospital day,bleeding rate,thrombin time (TT),prothrombin time (PT),activation part thrombin time ( APTT),fibrinogen (Fg),antithrombin Ⅲ ( AT Ⅲ ) and D-dimer.Results ( 1 ) The differences of mortality were both insignificant in the control group comparel with Group A and Group B respectively at day 28 ( P ＜ 0.05 ).(2) The ICU stay of three groups showed significant differences ( P ＜ 0.01 ),with longer stay of Groups A and B than control group ( P ＜ 0.01 ) and longer stay of Group A than Group B ( P ＜ 0.05 ).( 3 ) Except for AT Ⅲ ( P ＜ 0.01 ),other blood coagulation indices showed no significant difference among three groups.(4) The differences of bleeding rate were not significant between Group A and control group (P ＞ 0.05),but significant between Group B and control group (p ＜ 0.05 ).(5) Related factor analysis indicated significant relationship between AT Ⅲ level and bleeding rate (P ＜0.01 ).ConclusionsLow dose heparins and LMWHs are beneficial to controlling traumatic DIC,but the heparin therapy adjusted by the level of AT Ⅲ with marked correlation bleeding rate shows lower bleeding rate as compared with LMWHs.
