Objective To compare the image quality and adverse effects among different concentrations of nonionic iodinated con-trast media in hysterosalpingography (HSG).Methods 99 female infertile patients were recruited in this study for HSG and were averagely divided into Group A,B and C.The application of contrast media were as follows:iomeprol injection(400 mg I/mL)for Group A,iopamidol injection (370mg I/mL)for Group B,iohexol injection(300 mg I/mL)for Group C.The image quality was in-dependently evaluated by two doctors using a 3-point scale (1 -3 score)and adverse effects were recorded.Results (1 )Scores of image quality:all images met diagnostic desire with (2.55±0.5 1)score in Group A,(2.42±0.50)score in Group B,(2.21±0.42) score in Group C.There were statistically significant differences among goups(H =7.790,P =0.022).Kappa values were 0.693 in Group A,0.687 in Group B,0.672 in Group C.(2)Adverse effects:4 cases in Group A(12.12%),3 cases in Group B(9.09%), 2 cases in Group C(6.06%),which showed no statistically significant differences(χ2 = 0.733,P =0.693).Conclusion The three kinds of concentrations of nonionic iodinated contrast media can all be applied in HSG.The higher of iodinated concentration,the better of image contrast.

This paper elaborated the research progress on transduction mechanisms of obese polycystic ovary syndrome (PCOS) and insulin resistance (IR). The action mechanisms of kidney-tonifying, spleen-invigorating and phlegm-resolving in the treatment of obese PCOS and IR were explored. It provided new ideas for the treatment of obese PCOS patients in the clinical practice of traditional Chinese medicine (TCM) gynecology. Literatures on TCM theories and modern signal pathways were used in the analysis of spleen-kidney deficiency and phlegm-dampness retention, which were the key pathogenesis of obese PCOS and IR. The scientific nature of treating obese PCOS and IR from the method of kidney-tonifying, spleen-invigorating and phlegm-resolving was demonstrated. The results showed that the scientific nature of treating obese PCOS and IR from the method of kidney-tonifying, spleen-invigorating and phlegm-resolving was initially demonstrated by the organic combination of TCM and modern medicine theories. It innovatively proposed that the treatment study strategy of transduction molecular mechanism took the interactive dialogue between PI-3K/Akt signal pathway and TNF-α signal pathway as its target. The regulatory role and action mechanism of this method in the treatment of obese PCOS and IR were discussed.

This study was aimed to establish and evaluate obese polycystic ovary syndrome (PCOS) rat model. Rats were randomly divided into the blank control group, high-fat model group, insulin (INS) combined human chorionic gonadotropin (HCG) model group, and INS combined HCG plus high fat emulsion model group. The obese PCOS rat model was induced by subcutaneous injection of INS and HCG on the nape, respectively. The intragastric administration of high fat emulsion was also used in the PCOS rat model establishment. The estrous cycle of rat was monitored. The detection was also made the weight increasing rate of rats, luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), testosterone (T), high-density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG), cholesterol (TC), fasting plasma glucose (FPG), fasting insulin (FINS), 2 h blood glucose and 2 h INS. Calculation was made on the HOMA index, related viscera index and bilateral ovaries HE staining. The results showed that when INS combined HCG improved method (INS combined HCG plus high fat emulsion model group) rats were sacrificed, the body weight, weight increasing rate, ovary viscera index, T, LH, and HOMA index were significantly higher than that of the blank control group, high-fat model group and INS combined HCG model group (P < 0.05,P < 0.01); HDL was significantly decreased (P < 0.05,P < 0.01). FPG, FINS, and 2 h INS of the INS combined HCG improved method group were significantly higher than that of the high-fat model group (P <0.01). It was concluded that INS combined HCG improved method was one of the ideal animal model establishment methods in the pathogenesis study of PCOS.

Objective: To understand the status and relationship between bullying behaviors and subjective well-being among left-behind students in Bijie,and to provide reference for the governments to support the development of policies and intervention. Methods: A total of 735 left-behind students were investigated on the spot with the Olweus Bully Questionnaire and Adolescent Subjective Well-being Scale. Results: Among the 735 left-behind students, 28.71% were found of participating in behaviors of bullying. More boys involved behaviors of bullying (bullies,victims and bully-victims) others than the girls(χ2=25.93, P<0.05), Bullying was more likely to be reported among children with poor peer relations(χ2=12.46, P<0.05). Total scores of the feelings of friendship，family，freedom,negative emotion and life differed significantly among different bullying roles(F=12.76, 2.86, 3.30, 5.98, 4.72, P<0.05). Multivariate analysis showed that there were many factors affecting the subjective well-being of these students, such as bullying behaviors, relationship with their classmates, academic record, the frequency which they contacted with parents(P<0.05). Conclusion Bullying is highly prevalent among left-behind children in Bijie. Effective prevention and control mechanisms should be established at the social, school and family levels to reduce the occurrence of bullying. Attention should be paid to the psychological and behavioral dynamics of left-behind middle school students, so as to improve their happiness.

[ABSTRACT]OBJECTIVETo investigate the therapeutic effect of early combination treatment with intratympanic glucocorticoid injection for sudden sensorineural hearing loss(SSNHL).METHODSTotal of 178 patients with diagnosis of SSNHL, including 44 with hearing loss at middle-low frequencies,50 at high frequencies,44 at all frequencies and 40 at total deafness, were randomly divided into combination treatment group (CT group) and systemic oral prednisone group (OP group).CT group (82 patients) received intratympanic administration of methylprednisolone and oral prednisone in tapering doses. Pure-tone threshold audiometry (PTA) was performed at week 8 after beginning of therapy. RESULTSIn middle-low frequencies, the final PTA and PTA improvement were 26.14±24.82 dB and 42.23±1.61 dB in CT group respectively, and were 37.91±13.98 dB and 30.00±13.30 dB in OP group respectively (both P<0.05). In high frequencies, all frequencies and total deafness SSNHL group, the differences of the final PTA and PTA improvement were not statistically significant in both groups. The PTA improvement in CT group for total deafness (26.52±14.03) dB was more than that of OP group (22.06±11.17)dB (t=2.361,P<0.05). In middle-low frequencies, the recovery rate was 72.73%(16 cases) in CT group, and 40.91% (9 cases) in OP group, the difference was significant (χ2=4.539,P<0.05), but not in apparent effective rate, effective rate and total effective rate. In high frequencies, all frequencies and total deafness, there were no significant differences in therapeutic effect. The recovery rate of total CT group (40.24%) was significantly increased compared with that of OP group (26.04%)(χ2=4.061,P<0.05), the differences of apparent effective rate, effective rate and total effective rate were not statistically significant in both groups.CONCLUSIONFor low-middle frequencies SSNHL, the early combination treatment with intratympanic glucocorticoid injection leads to higher hearing recovery and therapeutic effect compared with traditional oral prednisone. Systemic application should be applied for high frequencies, all frequencies and total deafness of SSNHL.

Objective:To analyze the advantages of the impact of physical activity management under medical supervision on body components and healthy physical fitness.Methods:A total of 106 healthy adults who participated in physical activity management activities in the Health Management Center of Sichuan Academy of Medical Sciences & Sichuan Provincial People′s Hospital from April 1 st 2020 to May 31 th 2021 were enrolled. The subjects were equally divided into a medical supervision group and a self-supervision group with random number table. Both groups performed a 8-week physical activity intervention, followed by the model of “a combination of online home physical activity with offline team exercise, and team exercise interaction with individual physical activity guidance”, while health education was provided and wearable devices were worn to collect exercise data. The medical supervision group completed the set number of exercises under the supervision of the team, with on-site exercise guidance. They were required to participate in weekly one-to-one on-site instruction. The self-management group carried out exercises and participated in weekly one-to-one instruction in accordance according to their own will with online feedback. During the study, 6 cases withdrew, and 52 cases in the supervision group and 48 in the self-management group were obtained. The t and Wilcoxon tests were used to compare the body components and physical fitness of the two groups before and after intervention. Results:The amount of exercise in the supervision group was significantly higher than that in self-management group (1 359 vs 615), and there was no significant differences in exercise intensity (mean heart rate, maximum heart rate and exercise duration) between the two groups (all P>0.05). After the intervention, the body weight, body mass index (BMI), percent body fat, subcutaneous fat area and strength fitness of the supervision group were significantly lower than those before the intervention [(55.36±6.37) vs (56.11±6.33) kg, (21.48±2.85) vs (21.73±2.47) kg/m 2, (27.38±5.34) % vs (28.53±4.99) %, (119.56±48.45) vs (128.70±50.10) cm 2, (24.48±6.37) vs (26.07±5.29) kg], while the cardiorespiratory endurance, flexibility fitness and agility fitness were significantly higher [(33.57±5.06) vs (30.32±4.59) ml·kg -1·min -1, (14.71±7.51) vs (10.54±7.54) cm, (0.44±0.08) vs (0.48±0.05) s] (all P<0.05). After the intervention, the body weight, muscle mass and lean body mass in self-management group were all significantly higher than those before the intervention [(56.83±8.09) vs (56.45±8.22) kg, (38.28±3.19) vs (38.24±5.17) kg; (40.80±4.16) vs (40.32±4.95) kg], and agility fitness was significantly lower [(0.64±0.39) vs (0.49±0.05) s] (all P<0.05). It was also found that improvements regarding the following three indicators were more significant in the supervision group: visceral fat, balance and agility fitness (all P<0.05). Conclusions:Physical activity intervention under medical supervision can significantly improve the body components and physical fitness in healthy adults, as well as exercise compliance and validity.

Objective To explore the needs of community pharmacy services in elderly hypertensive patients in the community, especially empty-nest elderly patients. Methods Elderly hypertensive patients living in Ouyang street were randomly selected and divided into empty-nest and non-empty-nest groups by cluster random sampling method. The basic information of the respondents, the frequency of hypertension monitoring, the taking of hypertensive drugs, and the taking of other drugs were compared and analyzed. Results In term of “blood pressure monitoring frequency”, the daily pressure measurement of the empty-nest group and the non-empty-nest group accounted for 33.6% and 19.3%, respectively. There was significant difference between the two groups (P<0.05).In term of “the varieties of hypertension drugs” and taking 3 kinds of hypertension drugs at the same times, the empty-nest group accounted for 28.8% and the non-empty-nest group accounted for 16.7%, and the difference between the two groups was significant (P<0.05)；In term of “the varieties of drugs” and taking 1-2 kinds of Chinese patent drugs at the same time, the empty-nest group accounted for 39.6% and the non-empty-nest group accounted for 26.0% , and the difference between the two groups was significant (P<0.05)。Conclusion Community elderly patients with hypertension, especially empty-nest elderly patients have an urgent need for community pharmacy services，Community pharmacy services personnel should provide personalized and targeted medication education and guidance to elderly patients, especially empty-nest elderly patients, to promote the rational drug use in elderly patients.

【Objective】 To investigate the quality changes of suspended red blood cells (SRBCs) prepared from the blood of Tibetan high Hb population, and explore the availability and safety of blood collected from Tibetan high Hb population. 【Methods】 The voluntary blood donors were grouped according to the Hb concentration at the initial screening: female blood donors from Tibet Autonomous Region (>3 500 m) with Hb≥190 g/L and male blood donors with Hb≥210 g/L were classified as plateau high hemoglobin group. A total of 13 male blood donors from Tibet Autonomous Region were recruited. And the female blood donors (n=13) with Hb(115~165) g/L and male blood donors (n=12) with Hb(120~185) g/L from Chengdu were classified as control group. Whole blood of 200 mL specification was centrifuged to remove the plasma, and MAP additive solution was added to prepare SRBCs, then SRBCs were divided into four aliquots (50 mL/bag and stored at 4℃. Parameters as blood routine, free Hb and hemolysis rate were measured aseptically at day 1, 14, 21, 35 of storage. And 10 mL SRBCs was used to extract membrane proteins for tyrosine phosphorylation detection of band 3 protein. 【Results】 The RBCs counts(×10¹²/L), hematocrit(%) and hemoglobin(g/L) of Tibetan high Hb group and control group were 6.76±0.95 vs 4.65±0.52, 63.3±6.8 vs 43.1±4.4 and 214.4±19.8 vs 143.2±16.9 (P<0.01). The erythrocyte deformability test on the day 1, 14, 21, 35 of storage showed that the deformability of SRBCs prepared from Tibetan high Hb group was significantly lower than that of the control group under shear stress of 3, 5.33, 9.49, 16.87, and 30 Pa, while the hemolysis rate of SRBCs prepared from the Tibetan high Hb group and the control group on the day 1, 14, 21, 35 were 0.050 2±0.040 2 vs 0.022 2±0.011 1, 0.055 4±0.043 vs 0.032 1±0.028 7, 0.061 2±0.025 9 vs 0.034 3±0.031 7 and 0.069 6±0.032 0 vs 0.044 0±0.033 3 (P<0.05). Western blotting showed that the cytoplasmic N-terminal Y21 of band 3 protein of SRBCs prepared from Tibetan high Hb group was highly phosphorylated. 【Conclusion】 The deformability of SRBCs prepared from the Tibetan high Hb group was significantly lower while the hemolysis rate of SRBCs was higher than that of the control group. The hemolysis rate of the SRBCs at the end of storage prepared from the Tibetan high Hb group meets the requirements of the national standard GB18469-2012(<0.8%). The increase of hemolysis rate of SRBCs prepared from the Tibetan high Hb group was closely related to the phosphorylation of band 3 protein.
