ObjectiveTo investigate the prevalence of polycystic ovary syndrome （PCOS） among female college students at a university in Fuzhou City， Jiangxi Province， and to facilitate early detection and intervention of PCOS. MethodsUsing a stratified sampling method， a total of 450 female freshmen were randomly selected for PCOS screening. A self-designed questionnaire was used for data collection， covering menstrual status， high androgen signs， lifestyle， dietary habits， and awareness of PCOS. Sample t test and χ² test were used to compare the basic information and dietary habits between PCOS and non-PCOS cases. The correlation between various indicators and the prevalence of PCOS was analyzed by a logistic regression model. ResultsA total of 12 PCOS cases were identified， with a prevalence rate of 2.99%. PCOS cases exhibited statistically significant differences compared to non-PCOS cases in terms of waist-to-hip ratio， waist circumference， abdominal obesity， the proportion of overweight or obese individuals， and a preference for sweet food （all P<0.05）. Multivariate logistic regression analysis revealed a significant correlation between preference for sweet food and the occurrence of PCOS （OR=4.858， 95%CI=1.199‒19.675，P=0.027）， as well as a significant correlation with PCOS accompanied by abdominal obesity （OR=7.083， 95%CI=0.773‒64.937， P=0.048）. Among the female college students surveyed， 37.90% had never heard of PCOS， 51.62% were only familiar with the name of the disease， and 10.47% had attempted to search for PCOS-related information. ConclusionThe prevalence of PCOS among female college students should not be overlooked and unhealthy dietary habits may be a crucial factor contributing to the occurrence of PCOS during this period. Early screening for PCOS during puberty is crucial.

Objective:To study the iodine nutritional status of pregnant women in the third trimester in the Southwest of Shandong Province, analyze its impact on their cardiac electrical activity, and provide a basis for scientific supplementation of iodine during pregnancy.Methods:From January 2021 to June 2022, a cross-sectional survey was conducted using cluster random sampling method. According to the inclusion and exclusion criteria, 200 pregnant women in the third trimester were selected from 3 tertiary hospitals in three cities in the Southwest of Shandong Province, and were divided into the third trimester group ( n = 600), and 100 non-pregnant women were selected as the control group ( n = 300). The urinary iodine content was detected by arsenic-cerium catalytic spectrophotometry, and the pregnant women in the third trimester group were subdivided into iodine deficiency subgroup [G1 subgroup, median urinary iodine (MUIC) < 150 μg/L] based on the MUIC, iodine excess subgroup (G2 subgroup, MUIC≥500 μg/L) and moderate iodine subgroup (G3 subgroup, 150 μg/L≤MUIC < 500 μg/L). Chemiluminescence immunoassay was used to measure the serum levels of thyroid-stimulating hormone (TSH), free thyroxine (FT 4) and free triiodothyronine (FT 3). The cardiac electrical indexes were detected by a 12-lead surface electrocardiogram (ECG) machine. Results:There was no statistically significant difference in urinary iodine levels between pregnant women in the third trimester group and non-pregnant women in the control group among the 3 tertiary hospitals in the Southwest of Shandong Province ( H = 3.63, 3.27, P > 0.05). In the third trimester group, the proportion of pregnant women in the G1, G2 and G3 subgroups was 27.67% (166/600), 6.83% (41/600) and 65.50% (393/600), respectively. There was a statistically significant difference in urinary iodine levels between the subgroups and the control group ( H = 11.56, P < 0.001). The serum FT 3 and FT 4 levels in the G2 subgroup were lower than those in the G1 and G3 subgroups ( P < 0.001), but there was no statistically significant difference in serum TSH levels among the three subgroups ( P > 0.05). The normal rates of ECG in the G1, G2, G3 subgroups, and the control group were 38.55% (64/166), 41.46% (17/41), 92.37% (363/393), and 95.33% (286/300), respectively. The difference between the groups were statistically significant (χ 2 = 461.25, P < 0.001), the normal rate of ECG in the G1 and G2 subgroups was lower than that in the control group ( P < 0.001). Short P-R intervals and ST-T changes were the most common abnormal ECG in the third trimester group. Conclusions:The incidence of iodine deficiency, iodine excess, and other abnormal iodine nutritional status in pregnant women in the third trimester of the Southwest of Shandong Province is relatively high. Short P-R intervals, ST-T changes, and other arrhythmia caused by this are more common. It is necessary to strengthen monitoring of iodine nutritional status and ECG during pregnancy, and adjust intervention strategies such as iodine supplementation in a timely manner.

Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.

Objective:To observe the effect of esketamine on cardiac index in patients undergoing lumbar surgery in prone position under general anesthesia.Methods:Forty-five patients with prone lumbar surgery after general anesthesia in Hunan Provincial People′s Hospital from March to July 2021 were divided into observation group (24 cases, group A) and control group (21 cases, group B) according to random number table method. Group A received 0.5 mg/kg esketamine intravenously during induction, and 0.15 mg/(kg·h) esketamine intravenously for 2 h after prone position. Group B received the same amount of normal saline. Both groups were given sevoflurane and remifentanil during operation to maintain anesthesia, and sufentanil was given intermittently during operation. The mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic pressure (DBP), cardiac index (CI), and heart rate (HR) before induction (T 0), during endotracheal intubation (T 1), 5 minutes after intubation (T 2), 5 minutes after prone position (T 3), 10 minutes after prone position (T 4), 30 minutes after prone position (T 5), 45 minutes after prone position (T 6), 60 minutes after prone position (T 7), 90 minutes after prone position (T 8), and 120 minutes after prone position (T 9) were recorded; The total dosage of norepinephrine 2 hours after anesthesia to prone position and extubation time after operation were also recorded. The Visual Analogue Scale (VAS) was performed 15 minutes after extubation, 6 and 24 hours after operation. Results:There was no significant difference in CI between T 3-T 9 and T 2 in group A ( P>0.05); the CI of group B at T 3-T 7 was significantly lower than that at T 2 (all P<0.05); there was no significant difference in CI between T 8-T 9 and T 2 in group B (all P>0.05); There was no significant difference in CI between group A and group B at T 0-T 2 (all P>0.05). The CI of group A at T 3-T 9 was significantly higher than that of group B (all P<0.05); The dosage of norepinephrine in group A was significantly lower than that in group B ( P<0.05); There was no significant difference in HR, MAP, SBP and DBP between the two groups at different time points (all P>0.05); there was also no significant difference in extubation time and VAS scores at 15 minutes, 6 hours and 24 hours after extubation between the two groups (all P>0.05). Conclusions:Intraoperative application of esketamine can increase CI after prone position and reduce the amount of norepinephrine during lumbar surgery.

Objective To reveal the mechanism of action of AS-Ⅳ on HepG2 cells based on molecular dynamics simulation and experimental evaluation. Methods We constructed a "drug-disease" network pharmacological map, analyzed the core genes of astragaloside Ⅳ (AS-Ⅳ) in HCC, screened key signaling pathways, and established a "drug-target" molecular dynamics model. In vitro assay was used to detect migration, proliferation and invasion abilities. Flow cytometry and qRT-PCR were used to detect the effect of AS-Ⅳ on the cell cycle and apoptosis, and the expression of core gene of HepG2. Results The core target of AS-Ⅳ acting on HCC was VEGFA. Compared with the control group, the high concentration of AS-Ⅳ significantly inhibited the migration, invasion and proliferation of HepG2 cells, blocked the metastasis of HepG2 cells from G₁ to G₂ phase, promoted their apoptosis, down-regulated VEGFA expression and up-regulated TGF-β1 expression. Conclusion AS-Ⅳ may inhibit the proliferation of hepatocellular carcinoma cells through multi-target and multi-pathway.

Objective:To explore the correlation between fluoride intake and serum alkaline phosphatase (ALP) in pregnant women of different gestational periods in endemic fluorosis area.Methods:Pregnant women in Rencheng District, Jinxiang County, Jiaxiang County of Jining City and Yuncheng County of Heze City were selected in April 2020. According to the gestational weeks, pregnant women were divided into early pregnancy group (0 - 12 weeks), middle pregnancy group (13 - 27 weeks) and late pregnancy group (> 27 weeks). The levels of urinary fluoride, ALP, osteocalcin (BGP), C-terminal peptide of β-Ⅰ collagen (β-CTX) and N-terminal propeptide of type Ⅰ collagen (PINP) of pregnant women in each group were measured, and the correlation between urinary fluoride and ALP, BGP, β-CTX, and PINP in pregnant women of different gestational periods was analyzed.Results:A total of 372 pregnant women were selected, including 97 cases in early pregnancy group, 169 cases in middle pregnancy group and 106 cases in late pregnancy group. There was no significant difference in urinary fluoride level between the three groups [(1.20 ± 0.25), (1.23 ± 0.19), (1.24 ± 0.30) mg/L, P > 0.05]. There was significant difference in serum ALP among the three groups ( P < 0.05), among them, the ALP level in early pregnancy was significantly lower than those of middle pregnancy group and late pregnancy group ( P < 0.05), and the ALP level in middle pregnancy was significantly lower than that of late pregnancy group ( P < 0.05). There was no significant differences in serum β-CTX among the three groups ( P > 0.05). There were significant differences in serum BGP and PINP levels among the three groups ( P < 0.05). The serum BGP and PINP levels in late pregnancy group were significantly higher than those of early pregnancy group and middle pregnancy group ( P < 0.05), and there were no significant differences in serum BGP and PINP levels between early pregnancy group and middle pregnancy group ( P < 0.05). There was a significant positive correlation between urinary fluoride and ALP in early pregnancy group ( r = 0.364, P < 0.05), but no significant correlation between urinary fluoride and BGP, β-CTX and PINP ( r = 0.164, 0.117, 0.136, P > 0.05). There was a significant positive correlation between urinary fluoride level and ALP in middle pregnancy group ( r = 0.417, P < 0.05), but no significant correlation between urinary fluoride level and BGP, β-CTX and PINP ( r = 0.127, 0.108, 0.129, P > 0.05). There was no significant correlation between urinary fluoride level and ALP, BGP, β-CTX and PINP in late pregnancy group ( r = 0.179, 0.158, 0.184, 0.149, P > 0.05). Conclusions:The urinary fluoride level of pregnant women in endemic fluorosis area is relatively stable in gestational period. The urinary fluoride level affects the ALP secretion of pregnant women in early and middle pregnancy. It is still necessary to strengthen the measures of improving water quality and defluoridation to reduce the impact of excessive fluoride intake on pregnancy complications in endemic fluorosis area.

Objective:To evaluate the diagnostic efficiency of hypersensitivity quantitative fecal immunochemical test (hs-qFIT) in colorectal cancer (CRC) and advanced adenoma.Methods:From July to December 2020, consecutive patients aged 50 to 75 years who underwent colonoscopy in Qilu Hospital of Shandong University, and had the Asia-Pacific colorectal screening score of medium or high risk were enrolled. All patients were requested to complete two hs-qFIT before colonoscopy. The diagnostic efficacy of hs-qFIT for CRC and advanced adenoma were assessed. Receiver operating characteristic curve of hs-qFIT in CRC diagnosis was drawn and the area under the curve (AUC) was calculated.Results:A total of 811 patients including 20 (2.5%) cases of CRC, 47 (5.8%) cases of advanced adenoma, 206 (25.4%) cases of non-advanced adenoma, 219 (27.0%) cases of non-adenomatous polyp, 76 (9.4%) cases of other colorectal lesions and 243 (30.0%) cases of non-colorectal lesions were involved. When the fecal hemoglobin cut-off values were 10, 30, 50, 75 and 100 ng/mL, the positive rates of hs-qFIT detection were 17.9% (145/811), 10.9% (88/811), 8.3% (67/811), 7.4% (60/811) and 5.8% (47/811), respectively. When the cut-off value of fecal hemoglobin decreased from 100 ng/mL to 10 ng/mL, the sensitivity of hs-qFIT for CRC diagnosis increased from 90.0% to 100.0%, and the specificity decreased from 96.3% to 84.2%; and the sensitivity of hs-qFIT for the diagnosis of advanced adenoma increased from 19.1% to 66.0%, and the specificity decreased from 95.0% to 85.1%. The AUC of hs-qFIT for the diagnosis of CRC and advanced adenoma were 0.981 (95% confidence interval ( CI) 0.970 to 0.992) and 0.846 (95% CI 0.807 to 0.886), respectively. When the optimal cut-off values were taken, the sensitivity and specificity were 100.0% and 91.2% for the diagnosis of CRC, and 66.0% and 85.3% for the diagnosis of advanced adenoma, respectively. Conclusion:Hs-qFIT can help the early screening of CRC and advanced adenoma.

Objective:To assess the efficacy and safety of common medication treatments on Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).Methods:PubMed, Embase, Web of Science, CNKI and Wanfang database were searched to find out the observational studies on medication treatment of KHE and TA. R-3.6.2 was used for calculate the pooled response rate and pooled adverse events rate. Meta analyses were performed according to KHE and TA with and without Kasabach-Merritt phenomenon (KMP) respectively. SPSS 22.0 was used to compare the pooled rates among each therapy.Results:A total of 30 studies regarding the medication treatment of KHE and TA were identified in this meta-analysis. Analyzed medicines included glucocorticoid, vincristine, sirolimus, propranolol, combination therapy of vincristine and glucocorticoid. The pooled results indicated that when referring therapy on KHE and TA with KMP, the pooled response rate of combination therapy (98.34%) and sirolimus (96.43%) was higher than that of other therapies, and the difference was statistically significant. The pooled adverse events rate of sirolimus (5.53%) was relatively higher than other modalities, with no statistically significance. As for therapy on KHE and TA without KMP, sirolimus (94.23%) had higher pooled response rate than glucocorticoid (31.25%), vincristine (46.15%) and propranolol (22.86%), with statistically significant differences. The pooled adverse events rate of sirolimus was 23.81%.Conclusions:Our findings indicate that for KHE and TA with KMP, combination therapy (sirolimus + glucocorticoid) and vincristine have the best efficacy, while the adverse events rate of sirolimus is relatively high. For KHE and TA without KMP, sirolimus has the highest response rate, but there is also a risk of serious adverse events. Glucocorticoid and vincristine have comparable response rate, which both inferior to sirolimus.
