Objective To analyze the risk factors of pulmonary embolism complications following laparoscopic bile duct exploration.Methods The data of 201 cases undergoing laparoscopic bile duct exploration from June 2002 to December 2014 were retrospectively analyzed.Fourteen risk factors of pulmonary cmbolism complications were evaluated by univariate analysis using no conditional binary Logistic regression.Results 23 patients developed pulmonary embolism complications (11.4％).Age (≥60y),Diabetes mellitus,coronary heart disease,history of cerebral infarction,preoperative shock,time of operation,ambulation after operation (≥3 d) were significant risk factors of pulmonary embolism complications (P ＜0.05).Multivariate Logistic regression analysis identified diabetes mellitus,coronary heart disease,history of cerebral infarction,time of operation,ambulation after operation (≥ 3 d) as independent risk factors of pulmonary embolism complications (P ＜ 0.05).Conclusions Diabetes mellitus,coronary heart disease,history of cerebral infarction,time of operation,ambulation after operation (≥ 3 d) are independent risk factors for pulmonary embolism complications following laparoscopic bile duct exploration.

In this paper is reported a new approach for the treatment of sarcoma--electroporation therapy. Electroporation can accelerate pharmacal molecules into cytoplasm by transient electromagnetic pulses. We have utilized the phenomenon of electroporation treating the S-180 sarcomas in the hind legs of the Kunming mice by intratumoral injection of anti-tumor agent at low dose. From the experiment, we learned that this approach can bring about remarkable effect. The technical procedure is easy to do and easy to control. Especially, it is useful in curing the flat tumor and has little untoward side effect. It deserves to be recommended as a new approach to treating the tumor in clinics.

We chose Hela cells as research object and studied the cytotoxicity generated by cyclophosphamide, an antitumor drug, after cell electroporation by the use of electromagnetic pulses. Comparison between the electroporation group and the contrast group revealed the greatly enhanced cytotoxicity of the electroporation group, indicating that under some conditions electromagnetic pulses can enhance the cytotoxicity of antitumor drugs. The results of this study provide reliable evidences and a feasible approach for clinical treatment of tumor.

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.
