Objective To study the value and significance of transcutaneous oxygen saturation monitoring from different parts in early diagnosis of neonatal critical congenital heart disease. Methods The transcutaneous oxygen saturation in right upper extremities and right lower extremities of neonates born in our hospital from July 2010 to July 2015 were detected at 2 hours to 24 hours after birth. If the transcutaneous oxygen saturation ≤ 0. 95 or difference between upper and lower extremities≥0. 03, color doppler ultrasound echocardiography were done. Results There were 24 385 cases of newborns in our study. 1 680 newborns with abnormal transcutaneous oxygen saturation ( ≤0. 95 or difference between upper and lower extremities ≥0. 03) were examined with color doppler ultrasound echocardiography. 204 cases of congenital heart disease (12. 1% ) contain 9 cases of critical congenital heart disease ( 0. 5% ) were detected. The critical congenital heart disease included complete transposition of great artery ( n = 3), tetralogy of Fallot ( n = 4), artery malformation ( n = 1), and pulmonary atresia with right ventricular dysplasia ( n = 1 ) . Conclusions Transcutaneous oxygen saturation monitoring from different parts has a high value for early detection of critical congenital heart disease in the newborn. It is recommended for clinical use in grass-roots hospitals.

Objective To observe the change of coagulation function in chronic stress depression model rats and the effects of elec-troacupuncture (EA) on it. Methods A total of 32 Sprague-Dawley rats were randomly divided in control group (n=8), model group (n=8), EA group (n=8) and fluoxetine group (n=8) after a week of acclimation. The 21-day unpredictable mild stress combined with solitarily feed-ing was used to make the depression model in the latter three groups, meanwhile EA group and the fluoxetine group accepted EA and fluox-etine. They were measured the prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB). Serum levels of 6-keto-prostaglandin F1α(6-keto-PGF1α), P-selectin, thromboxane B2 (TXB2) were determined with enzyme-linked im-munoabsorbent assay. Results The cross and rear scores were significantly lower in the model group than in the control group (P<0.01). The scores increased in EA group and the fluoxetine group (P<0.01) compared with the model group. Compared with the control group, PT, APTT and TT decreased (P<0.01), FIB increased (P<0.05), the level of 6-keto-PGF1αdecreased, the level of P-selectin and TXB2 increased (P<0.01) in the model group. Compared with the model group, PT, APTT and TT increased (P<0.05), the level of 6-keto-PGF1αincreased (P<0.01), and the level of P-selectin and TXB2 decreased (P<0.05) in EA group and the fluoxetine group, and FIB decreased in EA group (P<0.05). Conclusion The chronic stress depression rats are impaired in the coagulation function and platelet activation, and can be allayed with electroacupuncture and fluoxetine.

Objective: To investigate the influencing factors of colorectal cancer and precancerous lesions among cured leprosy patients, so as to provide insights into prevention of colorectal cancer among cured leprosy patients. Methods: All cured leprosy patients were recruited from each leprosy village (hospital) in Zhejiang Province from 2019 to 2020. Participants' demographic features, family and medical history of intestinal polyps, smoking, alcohol consumption, dietary behaviors and defecation during the recent three years were collected using questionnaire surveys. Colorectal cancer and precancerous lesions were diagnosed using rectal examination, electronic colonoscopy and histopathological examinations, and factors affecting the development of colorectal cancer and precancerous lesions were identified with a multivariable logistic regression model among cured leprosy patients. Results: Totally 100 cured leprosy cases were enrolled, including 72 men and 28 women, and with a mean age of (67.23±3.42) years. There were 13 cases with grade 0 leprosy disability, 16 cases with grade 1 leprosy disability and 71 cases with grade 2 leprosy disability. The detection of colorectal cancer and precancerous lesions was 5.00% and 26.00%, respectively. Multivariable logistic regression analysis showed that age of 65 years and older (OR=7.128, 95%CI: 5.019-10.123), disability (OR=4.591, 95%CI: 2.942-7.163), a medical history of intestinal polyps (OR=4.031, 95%CI: 3.052-5.325), eating moldy food frequently (OR=4.433, 95%CI: 2.920-6.729), seldom eating vegetables (OR=4.411, 95%CI: 3.204-6.071), bloody stools (OR=4.341, 95%CI: 2.771-6.799), mucous stools (OR=4.577, 95%CI: 2.771-7.559) and presence of depression (OR=3.935, 95%CI: 3.026-5.117) were statistically associated with the development of colorectal cancer and precancerous lesions among cured leprosy patients. Conclusion Advanced age, disability, history of intestinal polyps, frequent intake of moldy food, infrequent consumption of vegetables, bloody stools, mucous stools, and depression may increase the risk of colorectal cancer and precancerous lesions among cured leprosy patients.

To improve the diagnosis and treatment of renal oncocytoma and avoid unnecessary radical nephrectomy. The clinical data of 6 cases of renal oncocytoma diagnosed at the Second Xiangya Hospital Central South University from March 2005 to November 2010, including symptoms, laboratory tests, imaging, style of operation, pathological examination, and follow-up were retrospectively analyzed.There were no special symptoms and obvious abnormal laboratory tests in the patients. Two patients had relatively special imaging. Partial nephrectomy was performed in 2 cases of renal oncocytoma with typical imaging, while radical nephrectomy was performed on other patients because of misdiagnosis. No relapse and metastasis were found in the following 1 to 5 years.Renal oncocytoma is an uncommon benign tumor. Partial nephrectomy or tumor excision can be performed on patients diagnosed with renal oncocytoma according to typical imaging and intraoperative frozen section biopsy. The final diagnosis depends on pathological examination and regular follow-up is imperative for patients with renal oncocytoma.
