Objective:To investigate the clinical efficacy of electrical stimulation, biofeedback, and radiofrequency therapy in combination for the treatment of pelvic floor dysfunction.Methods:A total of 144 patients with pelvic floor dysfunction who received treatment in Lianyungang Maternal and Child Health Hospital from June 2020 to June 2022 were included in this prospective randomized controlled study. They were randomly assigned to undergo electrical stimulation combined with biofeedback (electrical stimulation group, n = 48), treatment with a novel radiofrequency technique (radiofrequency therapy group, n = 48), or electrical stimulation, biofeedback, and treatment with a novel radiofrequency technique (combined group, n = 48). Pelvic floor dysfunction, stress urinary incontinence, and pelvic floor myofascial pain were compared among the three groups. Pelvic organ prolapse quantification was compared among the three groups before and after treatment. Quality of life was evaluated. Results:The effective rates of treatment against pelvic floor dysfunction, stress urinary incontinence, and pelvic floor myofascial pain in the combined group were 95.83% (46/48), 97.92% (47/48), and 93.75% (45/48), respectively, which were significantly higher than 79.17% (38/48), 79.17% (38/48), 77.08% (37/48) in the radiofrequency group, and 75.00% (36/48), 77.08% (37/48), 72.92% (35/48) in the electrical stimulation group ( χ2 = 8.40, 9.77, 7.66, all P < 0.05). After treatment, the severity of pelvic organ prolapse in the combined group was significantly milder than that in the novel radiofrequency technique group and electrical stimulation group (both P < 0.05). The scores of the pelvic floor dysfunction questionnaire and urinary incontinence questionnaire in the combined group were significantly lower than those in the radiofrequency therapy group and the electrical stimulation group (both P < 0.05). Conclusion:Electrical stimulation, biofeedback, and radiofrequency therapy in combination can greatly strengthen the muscle strength of the pelvic floor, relieve urinary incontinence, reduce pelvic floor myofascial pain, and improve the quality of life of patients with pelvic floor dysfunction.

Objective:To investigate the prevention and risk factors of deep vein thrombosis (DVT) in the lower extremity after medial open wedge high tibial osteotomy (HTO).Methods:A total of 128 patients who underwent medial open wedge HTO in the Third Hospital of Hebei Medical University from January 2020 to October 2022 were retrospectively analyzed, including 45 males and 83 females, aged 59.3±6.8 years (range, 44-87 years). Postoperative anticoagulation with enoxaparin sodium was applied at a randomized dose of 4,000 AXaIU/d or 6,000 AXaIU/d. Gender, age, history of chronic diseases (hypertension, diabetes), smoking history, body mass index, and body fat percentage were collected. On admission, the risk of DVT was assessed using the Caprini scale and calf circumference was measured. Hemoglobin, D-dimer, antithrombin III, activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), fibrinogen degradation products (FDP), glutathione, glutathione, urea, creatinine, uric acid were recorded. Patients were divided into DVT group and non-DVT group according to whether DVT occurred after operation. Binary logistic regression was used to analyze the independent risk factors of DVT after HTO. The receiver operating characteristic (ROC) curve was plotted, and the area under curve (AUC) was calculated to analyze the predictive value of the postoperative Caprini scale in the occurrence of DVT after HTO.Results:A total of 128 patients were enrolled, 83 patients were treated with enoxaparin sodium 4 000 AXaIU/d and 45 patients were treated with enoxaparin sodium 6 000 AXaIU/d. According to the results of color Doppler examination of bilateral lower extremity veins on the third day after operation, DVT occurred in 39% (50/128) of patients, including 39 cases of calf intermuscular thrombosis, 6 cases of peroneal vein thrombosis, 4 cases of posterior tibial vein thrombosis, and 1 case of popliteal vein thrombosis. DVT occurred in 36% (30/83) of patients receiving 4 000 AXaIU/d enoxaparin sodium and 44% (20/45) of patients receiving 6 000 AXaIU/d enoxaparin sodium, with no statistically significant difference (χ 2=0.84, P=0.358). Univariate analysis showed that smoking history, postoperative Caprini scale≥8, and female may be associated with the development of DVT after HTO ( P<0.05). They were included in the binary logistic regression, and the results showed that postoperative Caprini scale≥8 was an independent risk factor for DVT after HTO. The ROC curve of postoperative Caprini scale for predicting DVT after HTO was drawn, and the AUC was 0.847 (95% CI: 0.73, 0.96), the optimal cut-off value was 8, and the sensitivity and specificity were 84.2% and 77.6%, respectively. Conclusion:Caprini scale≥8 is an independent risk factor for DVT after medial open wedge HTO. Caprini scale has a good value in predicting the occurrence of DVT after HTO. The recommended dose of enoxaparin sodium is 4 000 AXaIU/d for the prevention of postoperative DVT, and increasing the dose is not associated with a decreased risk of DVT.

Objective:To explore the effect of health education based on the forgetting curve in maintenance hemodialysis patients.Methods:A total of 84 patients undergoing maintenance hemodialysis in the First Affiliated Hospital of Nanjing Medical University from March 2017 to March 2020 were enrolled and divided into in the observation group (43 cases) and in the control group (41 cases) using the random number table. The control group received conventional health education, and the observation group conducted health education based on the forgetting curve. Six months after intervention, disease cognition level, self-management ability, quality of life of the two groups were compared.Results:Six months after intervention, disease cognition level, self-management ability, quality of life scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Health education based on the forgetting curve can help maintenance hemodialysis patients enhance the awareness of diseases, promote the development of self-management ability, and improve their quality of life.

Objective To research the clinical outcome of atypical glandular cell (AGC)according to various subtypes of HPV infection and histological pathology results.Methods The data of the liquid-bases cytology (LBP),HPV infection and histology in 102 cases of AGC at the gynecology outpatient department of our hospital from January 1 ,2009 to February 28,2014 were collected and performed the analysis on their clinical outcomes.Results Among 67 218 cases of LBP detection,102 cases were AGC with the total incidence rate of 0.15%.In the cases of AGC-NOS,67 cases were normal or benign lesions,11 cases were precancerous lesion and malignant lesions;in the cases of AGC treading to tumor,the benign,precancerous and malignant lesions were in 7,14 and 3 ca-ses respectively.At the same time in the cases of AGC-NOS,HPV infection was in 64 cases,in which 57 cases were high risk infec-tion(type 16,52,45)and 7 cases were low risk infection(type 6,11 ).The single infection,double infection and multiple infection were in 54,6 cases respectively;in the cases of AGC trends to neoplasm,HPV infection was in 19 cases,in which 18 cases were high risk infection(type 52,16,18)and 1 case was low risk infection(type 6),single infection and double infection were in 15 cases and 4 cases respectively.Conclusion AGC may play an important role for the forecast of cervical malignant lesions.The results of differ-ent HPV subtypes infection in AGC related tumors also play a certain role in the prediction of cervical neoplasia.Their combined a-nalysis is the important signal for judging the occurrence of gynecological cervical precancerous lesion and malignant tumor,i.e., AGC combining with the corresponding HPV subtype infection not only can make a judgement for the cervical lesions,but also pro-vides the basis for predicting the high risk existence of gynecological malignant tumor and provides constructive suggestions for Chi-na regional cervical carcinoma vaccine manufacturing and promotion.

Objective:To observe the effects of epidural labor analgesia during latency period on factors related to labor process.Methods:A total of 120 single fetus cephalic presentation primiparas,aged from 22 to 35,were enrolled and randomly divided into group undergoing epidural labor analgesia during latency period (group Q),group undergoing epidural labor anal-gesia during active period (group H),and control group without epidural labor analgesia (group C).Duration of each labor pe-riod,pain score and amount of bleed were compared among the groups.Venous blood was collected for determination of inter-leukin (IL-6,IL-8)and tumor necrosis factor-α(TNF-α)levels before latent phase of labor or before starting infusion of oxyto-cin (time 1),2 h after delivery (time 2)and 24 h after delivery (time 3).Results:The second stage of labor in group Q or group H was longer than that in group C and the difference was statistically significant(P <0.05).However,there was no sta-tistical significance regarding other stages of labor among the three groups (P >0.05).There was no statistical significance re-garding IL-6,IL-8 and TNF-αlevels among the three groups at each of the 3 time points above (P >0.05).Conclusions:Epi-dural labor analgesia during latency period or active period could prolong the second stage of labor to different degree,but it had little effect on the entire labor process.Epidural labor analgesia had no significant effect on serum cytokines related to the birth process.Changing the time point of epidural labor analgesia from active period to latency period could improve maternal com-fort,so that it is worthy of clinical application.

Objective To investigate the effects of extended care on the treatment compliance and the quality of life on discharged elderly patients with chronic heart failure. Methods One hundred and eight patients were randomly assigned to the experimental group and the control group with 54 patients in each, the experimental group received extended care for 1 year, including regular telephone and visit follow-up, supporting medical care, diet care, rehabilitation exercises and supervision of self-care. The control group underwent routine health education before discharge. Medical compliance and self-management ability were compared three months, six months and 1 year after discharge, evaluation score of life quality were also compared at discharge and one year after discharge between the two groups. Results There were no significant differences in medication, diet and regular follow-up visits between the two groups. However, the patients in the experimental group showed better compliance than the control group in the self-testing of urine, body weight,and recording of symptoms, body signs and required exercises. Additionally, the patients in the experimental group had higher scores than the control group in the daily life-skills, happiness and the quality of life. Conclusions The extended care significantly improved the treatment compliance and the quality of life in the elderly patients with chronic heart failure.

Objective To retrospectively evaluate the incidence and treatment of fungous infection compli-cations after hematopoietic stem cell transplantation. Methods The incidence, pathogenic microorganism, prophy-laxis,treatments of infectious complications in 150 patients, who accepted hematopoietic stem cell transplantation from September 1990 to Martch 2000 in our hospital were analyzed. Results The incidence of infectious complica-tions was 89.3% (134/150) in all 150 cases. Three patients (2%) died of the fungal infection. The incidence of the fungal infections was 32.5% (26/80) in patients who accepted treatment with impenem or/and ceftazidine, and 15.7% (11/70) in other patients without the above treatment (P<0.05). 12 fungal infection cases were treated with small-dosage of amphotericin B(10 mg/d) ,with the healing rate was 100%. Conclusion The strong antibac-terial prophylaxis can't reduce the incidence of infection ,but may increase the risk of fungal infection;small-dosage of amphotericin B is a new effective way to treat fungal infection.
