Objective: To explore the clinical effect of cotton pads under stitches when intradermal traction with sutures is used to repair of chronic wounds. Methods: From January 2009 to August 2016, 21 patients with 31 wounds were treated by continuous intradermal traction. Wound edges were sutured with 2-0 silk thread in horizontal mattress fashion, but not tied. Then small cotton pads were put under stitches to protect the skin around the wound. After that, the sutures on both sides of the wound edges were pulled to the center of the wound with a certain force. And the wound was sutured finally when the skin on both sides of the wound was closed enough. Results: All of 31 wounds healed without necrosis of the skin margin and 5 cases of lacerated wound caused by silk thread healed after dressing change. The healing time was (43.24±11.46) days, and there was scarcely hypertrophic scar at the stitches. This method was compared with the previous method of protecting stitches with silicone tubes( referring to past data). There was no significant difference in the healing time between the two methods (P=0.119), and less laceration occurred under the stitches with cotton pads (P=0.046). Conclusions It is a commendable method for treating chronic wounds to put cotton pads under the stitches while tracting the wound edges with sutures. It can effectively cushion the cutting force of the silk thread, protect the traction point and facilitate the replacement of the pads.

Objective: To understand the relationship between female breast cancer and occupational risk factors in Beijing, and provide scientific basis for the formulation of prevention strategies and measures. Methods: From June to December 2019, A 1: 1 case-control study was adopted, eight medical institutions in Beijing were selected as the research objects. Patients with breast cancer diagnosed by medical institutions were selected as case group and non breast cancer patients in the same medical institution as control group. A total of 973 subjects were included, including 495 in the case group and 478 in the control group. A one-to-one survey was conducted using a questionnaire uniformly compiled by the Beijing Centers for Disease Control and Prevention. The survey content mainly includes basic demographic characteristics and occupational risk factors. The Trait Coping Style Questionnaire (TCSQ) was used to investigate the corresponding methods, including two aspects: positive coping and negative coping. First, chi square test or Wilcoxon rank sum test were used for univariate analysis. Then Lasso regression was used to screen the risk factors of breast cancer. Finally, the risk factors were screened by multivariate logistic regression analysis. Results: Education lovel was 49.64%, body mass index (BMI) was 18.4~23.9 kg/m(2), accounting for 48.82%, marital status ws 84.48%. Compared with no night shift history, there was a significant increase in risk of breast cancer at night shift history (OR=1.70, 95% CI: 1.25~2.30, P<0.05) . Compared with most of the sitting posture and sometimes standing, the risk of breast cancer was increased, and the difference was statistically significant (OR=2.01, 95%CI: 1.40~2.90, P<0.05) . Conclusion: In the occupation risk factors, night shift work and working posture are related to the incidence of breast cancer in women, establishing a good schedule and avoiding long standing can effectively prevent and reduce the occurrence of breast cancer.

Objective To analyze the basic characteristics, drug features, prescription rules, and drug-symptom relationships of patients in the splenic deficiency and impairment stage, by data mining of medical records under the New Theory on Spleen Dampness Syndrome (Pi Dan Xin Lun, 《脾瘅新论》). Methods Medical records listed in the “New Theory on Spleen Dampness Syndrome – Understanding and Treatment of Metabolic Syndrome from the Perspective of Traditional Chinese Medicine”, and which were diagnosed with the spleen dampness syndrome at the splenic deficiency and impairment stage, during January 2004 and December 2016 were selected. These patients’ data, including basic information, clinical symptoms, laboratory examination results, traditional Chinese medicine (TCM) and western medicine diagnoses, treatment methods, prescriptions, etc., were collected. The collected data were subsequently compiled into a medical record database using the Epidata 3.1 data management software, followed by the use of Apriori algorithm provided in the SPSS Modeler 14.2 statistical software to investigate the association rules between drug-drug, drug-symptom, and drug-western medicine indices. Results (i) A total of 51 medical records were included, involving 17 types of syndromes. Among them, the top three with frequency ≥ 3 included “Phlegm and blood stasis, and thoracic obstruction” “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”, and “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”. Alternatively, of the 14 treatment methods, the top three treatments with frequency of ≥ 3 included “Activating Yang and eliminating turbidity, and removing phlegm and dredging channel blockage” “Strengthening the spleen and benefiting Qi, and eliminating phlegm to activate the channels”, and “Warming Yang and benefiting Qi, and expelling cold to remove obstructions”. Among the 15 prescriptions, the top three used with frequency ≥ 3 included Huangqi Guizhi Wuwu Tang (黄芪桂枝五物汤), Gualou Xiebai Banxia Tang (瓜蒌薤白半夏汤), and Ganjiang Huangqin Huanglian Renshen Tang (干姜黄芩黄连人参汤). Lastly, of the 83 drugs used for a total of 476 times, those with frequency ≥ 15 included Huanglian (Coptidis Rhizoma), Huangqi (Astragali Radix), Jiudahuang (Wine-processed Rhei Radix et Rhizoma), Jixueteng (Spatholobi Caulis), Shengjiang (Zingiberis Rhizoma Recens), Huangqin (Scutellariae Radix), and Guizhi (Cinnamomi Ramulus). (ii) For the drug-drug associations, under the criteria of support ≥ 15% and confidence = 100%, seven second-order association rules, seven third-order rules, and six fourth-order roles were identified. The top-ranking rule of each was “Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)” “Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)”, and “Baishao (Paeoniae Radix Alba) + Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Huangqin (Scutellariae Radix)”, respectively. Alternatively, the drug-symptom associations were analyzed under the criteria of support ≥ 5% and confidence = 100%, which derived eight second-order association rules, 31 third-order rules, and 30 fourth-order rules. The top-ranking association rule of each order was “Huangqi (Astragali Radix) → Limb edema” “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Limb numbness and pain”, and “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) + Huangqi (Astragali Radix) → Limb numbness and pain”, respectively. Similarly, the drug-western medicine index associations were investigated under the criteria of support ≥ 5% and confidence = 100%, and five second-order association rules, 16 third-order rules, and 16 fourth-order rules were identified. In this category, the top-ranking association rule of each order was “Qinpi (Fraxini Cortex) → Uric acid” “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) → Glycated hemoglobin”, and “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Glycated hemoglobin”, respectively. Conclusion Through association rule mining, this study objectively and quantitatively demonstrated the drug-drug, drug-symptom, and drug-physicochemical index associations of patients with the spleen dampness syndrome at the splenic deficiency and impairment stage treated by Academician TONG Xiaolin. The results indicated that treatment for these patients adopted the “state-target” syndrome differentiation method. The drug combination was characterized by “small prescriptions”, targeting both the patient’s symptoms and signs (syndrome target) and western medicine indices (treatment target). This study could provide references for future research on the academic thoughts and medical experience of Academician TONG Xiaolin.
