1.Clinical value and challenge of sentinel lymph node biopsy for cervical cancer
Journal of Chinese Physician 2021;23(2):178-182,188
Cervical cancer, a common malignant tumor in female reproductive system, seriously threatens women's life and health. The standard surgery for early cervical cancer is radical hysterectomy + pelvic lymphadenectomy±para-aortic lymph node sampling. Lymph node metastasis is an independent risk factor for the prognosis of cervical cancer patients. Several researches showed that the incident of lymph node metastasis in early cervical cancer was approximately 20%. Giving the complications and sequelae of systematic lymph node resection, its application in early cervical cancer is still doubted. The sentinel lymph node, where lymph node metastasis firstly occurs, attracts much attention in the surgical treatment of malignant tumors. Hence, sentinel lymph node biopsy (SLNB) came into being. Recent studies have indicated that SLNB is safe and feasible for early cervical cancer and SLNB is recommended to patients with early cervical cancer. This article will introduce the application of SLNB in cervical cancer in the recent years and discuss its clinical value and related challenges.

Objective To investigate the role of blood motilin and anorectal function in the pathogenesis of functional outlet obstructive constipation (OOC), and study if motilin and its receptor agonist are effective to treat OOC. [WTHZ]Methods Patients with OOC were selected according to colonic transit time and transit index. Twenty healthy subjects were also selected as control group. Anorectal manometry was performed, and blood motilin level was measured in patients with OOC and healthy subjects. Correlation between blood motilin level and anorectal function was analyzed. [WTHZ]Results Compared with healthy subjects, OOC patients had higher anal resting pressure, lower defecating pressure difference,larger minimum relaxation volume to elicit anorectal inhibitory reflex, and higher rectal sensation threshold. The plasma level of motilin was positively correlated with anal resting pressure, maximum squeeze pressure and anal defecating pressure, but was negatively correlated with defecating pressure difference between rectum and anal canal. Conclusion OOC patients had anal sphincter dysfunction in relaxtion, discoordination of annorectum during defecation, and Low sensitivity of rectum. OCC patients with the normal level of blood motilin may have more severe outlet obstructive tendency, and motilin and its receptor agonist are not suitable for treating OOC patients.

Objective To explore the analgesic effect of dicaine combined with penetration en-hancer applied to venipuncture with venous indwelling needle. Methods 60 patients treated with selec-five operation under epidural anesthesia were divided into the control group and the experimental group with 30 patients in each group. The control group was treated with conventional method of venipuncture. The experimental group was externally applied with dicaine combined with penetration enhancer 50 min-utes before the venipuneture in basilic or cephalic vein. Local reactions were observed after venipuncture and the analgesic effects were evaluated with visual analogue scale(VAS 0~100 mm). Results The analgesic ef-fect in the experimental group was obviously better than that of the control group with a significantly lower VAS. The maintaince of analgesic time in the experimental group lasted above 90 minutes. Condusious The analgesic effect of dieaine combined with penetration enhancer can be approved with a very high analgesia rate, its onset time is much shorter than conventional method and maintenance time is much longer.

Gastrointestinal bleeding is common in children. The causes of hemorrhage is numer-ous and varies with age. Most of them can be identified by conventional endoscopy and imaging examina-tion. For unexplained bleeding,especially repeated bleeding which failed to conservative therapy,a one-stop hybrid procedure of gastrduodenoscopy,colonoscopy and laparoscopy showed great clinical application value. Endoscopic hematischesis is widely used for minimally invasiveness,effectiveness,and recognition of biopsied lesions. With the progress of laparoscopic technology,single-port transumbilical laparoscopy is increasingly applied in pediatric gastrointestinal bleeding. While surgical exploration is still mandatory for massive hemorrhage in emergency circumstances.
