Objective:To analyze the risk factors affecting the efficacy of arterial balloon occlusion intervention in cesarean sections for women with placenta accreta spectrum (PAS).Methods:A retrospective study was conducted on 55 PAS patients who underwent arterial balloon occlusion during cesarean sections in the obstetrics department of the First Affiliated Hospital of Guangxi Medical University from January 2015 to March 2021. The patients were divided into two groups based on surgical blood loss: ≥2 000 ml group (27 cases) and <2 000 ml group (28 cases). Baseline data, surgical management, and pregnancy outcomes were analyzed between the two groups. For patients who underwent MRI, prenatal MRI characteristics were analyzed. Intergroup comparisons were performed using independent samples t-test, Mann-Whitney U test, or Chi-square test (or Fisher's exact test). Bonferroni correction was used for multiple comparisons. Results:(1) The variation in patients' bleeding volume across different years during the study period was not statistically significant. The proportion of placenta percreta in the ≥2 000 ml blood loss group was significantly higher than in the <2 000 ml group [placenta accreta, increta, and percreta in both groups were 0.0% (0/27) vs. 7.1% (2/28); 25.9% (7/27) vs. 53.6% (15/28); and 74.1% (20/27) vs. 39.3% (11/28), respectively; Fisher's exact test, P=0.019]. (2) The ≥2 000 ml group showed a trend towards higher rates of hysterectomy and failed uterine preservation after placental removal compared to the <2 000 ml group [25.9% (7/27) vs. 3.6% (1/28), Fisher's exact test], but the difference was not statistically significant ( P=0.074). (3) The ≥2 000 ml group had significantly higher blood loss, transfusion of ≥5 units of red blood cells, incidence of disseminated intravascular coagulation, longer surgery time, and higher postoperative transfer to intensive care unit rates compared to the <2 000 ml group [3 600 ml (2 550-5 050 ml) vs. 1 100 ml (600-1 500 ml), Z=756.00; 77.8% (21/27) vs. 21.4% (6/28), χ2=17.40; 33.3% (9/27) vs. 0.0% (0/28), Fisher's exact test; (253±94) min vs. (150±57) min, t=4.92; 40.7% (11/27) vs. 3.6% (1/28), χ2=11.13; all P<0.05]. The bladder injury rate in the ≥2 000 ml group showed a trend towards being higher than in the <2 000 ml group, but the difference was not statistically significant [22.2% (6/27) vs. 3.6% (1/28), Fisher's exact test, P=0.051]. There were no statistically significant differences in other maternal and neonatal outcomes between the two groups. (4) Among the study subjects, 50 patients had prenatal MRI data, with 22 in the ≥2 000 ml group and 28 in the <2 000 ml group. The ≥2 000 ml group had a significantly higher proportion of local exophytic masses, asymmetric placental thickening/shape, and placental invasion in the S2 region compared to the <2 000 ml group [81.8% (18/22) vs. 53.6% (15/28), χ2=4.38; 81.8% (18/22) vs. 50.0% (14/28), χ2=5.41; 95.5% (21/22) vs. 53.6% (15/28), χ2=10.72; all P<0.05]. Conclusions:When the placenta invades the S2 region and the depth is invasive, arterial balloon occlusion in cesarean sections for PAS still faces a high risk of massive hemorrhage. Prenatal MRI should focus on assessing the extent and depth of placental invasion to identify potentially severe PAS cases, thereby optimizing the clinical application of arterial balloon occlusion.

OBJECTIVE To clarify the core content of traditional Chinese medicine （TCM） policy in the provinces of China， so as to provide reference for optimizing the structure of the policy system of traditional Chinese medicine in China and assisting the inheritance and innovation of TCM industry in various regions. METHODS The websites of directly affiliated organs in 31 provinces， excluding Hong Kong， Macao and Taiwan， were retrieved to collect the TCM policies released from 2000 to 2021. The importance of keywords in the TCM policies of each province was measured based on term frequency-inverse documentation frequency （TF-IDF） keyword extraction method， and the similarities and differences were analyzed among TCM policies. RESULTS & CONCLUSIONS A total of 99 documents related to TCM policies of various provinces were obtained in this study， most of which were released after 2016. The theme of national TCM policy covered four aspects： building TCM talent team， perfecting TCM service system， strengthening TCM resource management and promoting TCM industry innovation. The TF-IDF values of “medical institutions”“traditional Chinese medicine”“medical treatment” were higher than other keywords in each province， indicating that the provinces paid more attention to the construction of TCM service system and the management of TCM resources than other aspects. Anhui and Jiangsu， Beijing and Henan， Hubei and Jilin， Hubei and Tianjin， and Hubei and Yunnan had the more degree of similarity in TCM policies， which all contained 16 of the same keywords. Therefore， the above regions should be encouraged to strengthen exchanges and cooperation and realize mutual promotion and joint development. Among all the keywords whose importance ratio was greater than 0.2，“ Tibetan medicine” was unique to Qinghai and Tibet，“ disease type” was unique to Guangdong， and the TF-IDF value of “supervision and management” in Beijing was higher， indicating that the emphasis of TCM policy formulation in different provinces was various. Meanwhile， the top 10 keywords of TF- IDF value in all provinces did not have words related to financial input， and the TF-IDF values of “informatization” in most provinces did not rank at the top. It is suggested to increase financial input or encourage social financing， and add “Internet+new business” in the field of TCM.

Objective To investigate the current status of urinary incontinence (UI) at the third trimester of pregnancy among primiparas in Guangdong Province.Methods The convenience sampling method was adopted to conduct the retrospective analysis on 714 primiparas in 3 hospitals of Guangdong Province from June 2015 to March 2016.International Consultation on Incontinence Questionnaire Urinary Incontinence Short-Form Chinese was used to investigate the occurrence status of UI at the third trimester of pregnancy among primiparas.And its influencing factors were analyzed.Results Among 714 primiparas,192 cases (26.9％) developed UI during the third trimester of pregnancy,in which stress UI accounted for 67.2％ (129/192).The prepregnancy BMI and abortion had statistical difference between.the UI patients and non-UI patients (P＜0.05).The multivariate Logistic regression results showed that pre-pregnancy BMI was correlated with UI at the trimester stage of pregnancy (OR =1.077,P＜0.05).Conclusion Pre-pregnancy BMI might be an independent risk factor of UI occurrence at the third trimester of pregnancy.

Objective: To establish an optimal extraction process of the total glycoalkaloids in Solanum tuberosum L. and then study the anti-inflammatory activity. Methods:The extraction process of the total glycoalkaloids was optimized by orthogonal design. Compared with that of the total glycoalkaloids in Rhizoma Dioscoreae Melanophymatis and fresh potato pieces, the anti-inflammatory ac-tivity of the total glycoalkaloids in Solanum tuberosum L. was evaluated by mouse ear swelling model induced by xylene, rat paw swell-ing model induced by carrageenan, granuloma model caused by cotton and blood capillary permeability experiments. Results:The opti-mal extraction conditions were as follows:the extraction temperature was 65℃, 10-fold amount of methanol was used for twice extrac-tion with 45 min per time. The total glycoalkaloids from the optimal extraction had obvious anti-inflammatory activity,and the effect was related to the content ofα-chaconine. Conclusion:The results show that the order of different factors affecting the extraction rate is ex-traction temperature> extraction time, and the total glycoalkaloids in Solanum tuberosum L. has good anti-inflammatory effects in mice and rats.
