OBJECTIVE: To compare clinical effect of arthroscopic double row fixation and single row fixation in treating Ideberg typeⅠA scapular glenoid fracture. METHODS: From June 2018 to December 2022, 26 patients with Ideberg typeⅠA scapular glenoid fracture treated with shoulder arthroscopy were divided into single-row anchor group and double-row anchor group according to the fixation method of fracture block. There were 12 patients in single-row anchor group, including 7 males and 5 females, aged from 25 to 53 years old with an average of (38.42±9.61) years old;the time from injury to operation ranged from 2 to 7 days with an average of (4.75±1.82) days. There were 14 patients in double-row anchor group, including 10 males and 4 females, aged from 21to 53 years old with an average of (37.36±10.19) years old;the time from injury to operation ranged from 1 to 8 days with an average of (4.21±2.01) days. The changes of shoulder joint flexion, abduction, lateral lateral rotation, Constant-Murley shoulder function score and Rowe scores were compared between two groups before operation and 1 year after operation. The percentage of bone mass in pelvis area before operation and the percentage of bone defect in pelvis area at the latest follow-up were compared between two groups. RESULTS: All patients were followed up for 12 to 15 months with an average of (13.08±1.17) months in single-row anchor group and 12 to 15 months with an average of (13.29±1.07) months in double-row anchor group, with no statistical significance between two groups (P>0.05). The results of anterior flexion, abduction and lateral lateral rotation in single-row anchor group were(86.67±6.62) °, (79.50±5.68) °, (38.17±1.70) ° before operation, and (162.50±4.52)°, (169.17±3.35)°, (50.67±10.20)° at 1 year after operation; while in double-row anchor group were (84.14±5.48) °, (81.71±5.20) °, (39.29±3.63) ° before operation and (162.29 ± 5.53) °, (167.14±3.61) °, (56.93±9.56) ° at 1 year after operation;the difference between two groups before operation and 1 year after operation was statistically significant (P<0.05). There were no significant difference between two groups (P>0.05). Constant-Murley scores and Rowe scores in single-row anchor group were (55.42±3.75), (43.75±18.49) before operation and (94.83±2.21), (95.42±4.50) at 1 year after operation, respectively;while in double-row anchor group were (54.50±7.88), (41.79±18.25) before operation and (94.36±4.73), (95.00±4.80) at 1 year after operation;there was no significant difference in Constant-Murley score and Rowe score between two groups before operation and 1 year after operation (P>0.05). There was significant difference in the percentage of bone mass in pelvis area between two groups before operation (P>0.05). There was no significant difference in the percentage of bone defect in the shoulder area between single-row anchor group(4.42±1.51)% and double-row anchor group (2.71±1.44)% at 1 year after operation (P<0.05). CONCLUSION Both single and double row fixation techniques for the treatment of Ideberg typeⅠA scapular glenoid fracture could receive satisfactory functional recovery. However, double-row fixation has more advantages in reducing bone resorption of fracture mass.

G protein-coupled receptor (GPR) 40, as one of GPRs family, plays a potential role in regulating glucose and lipid metabolism. To study the effect of GPR40 novel agonist SZZ15-11 on hyperglycemia and hyperlipidemia and its potential mechanism, spontaneous type 2 diabetic KKA^y mice, human hepatocellular carcinoma HepG2 cells and murine mature adipocyte 3T3-L1 cells were used. KKA^y mice were divided into four groups, vehicle group, TAK group, SZZ (50 mg·kg^-1) group and SZZ (100 mg·kg^-1) group, with oral gavage of 0.5% sodium carboxymethylcellulose (CMC), 50 mg·kg^-1 TAK875, 50 and 100 mg·kg^-1 SZZ15-11 respectively for 45 days. Fasting blood glucose, blood triglyceride (TG) and total cholesterol (TC), non-fasting blood glucose were tested. Oral glucose tolerance test and insulin tolerance test were executed. Blood insulin and glucagon were measured via enzyme-linked immunosorbent assay (ELISA). After mice′s execution, liver tissue was harvested to test TG and TC content. Then pathological morphology of liver was observed through hematoxylin-eosin (HE) staining, and the lipid metabolism relative signal pathway was analyzed by Western blot and RT-PCR. The experiments were approved by the Institutional Animal Care and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College. At the same time, Akt phosphorylation level in HepG2 cells and adiponectin in 3T3-L1 cells treated with TNFα were measured with Western blot. The results show that SZZ15-11 not only decreased blood glucose and lipid, improved insulin sensitivity, but also increased fasting blood glucagon and promoted insulin secretion after glucose loading in KKA^y mice. Additionally, SZZ15-11 alleviated hepatic steatosis and liver dysfunction in KKA^y mice. In liver tissue, SZZ15-11 increased AMPKα phosphorylation level and cholesterol metabolism relative gene Abcg8 transcription. In HepG2 cells, SZZ15-11 increased Akt phosphorylation level. In adipocyte 3T3-L1, SZZ15-11 recovered the decreased adiponectin expression by TNFα. This study proved that GPR40 agonist SZZ15-11 could be a candidate compound for regulating glucolipid metabolic disorder.

Objective To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures.Methods Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively,and divided into open reduction and internal fixation group(posterior medial approach hollow anchor system fixation)and arthroscopic fixation group(Endobutton with loop plate fixation under arthroscopy).There were 20 patients in open reduction and internal fixation group,including 16 males and 4 females,aged from 26 to 74 years old with an average of(42.9±18.8)years old;13 patients on the left side and 7 patients on the right side;12 patients were classi-fied to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;14 patients were grade Ⅱ and 6 patients were grade Ⅲ in back drawer test.There were 18 patients in arthroscopic fixation group,including 11 males and 7 fe-males;aged from 24 to 70 years old with an average of(53.5±13.4)years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classifica-tion;11 patients were grade Ⅱ and 7 patients were grade Ⅲ in back drawer test.Operation time,blood loss,and quality of im-mediate reduction were compared between two groups.Knee range of motion,knee back drawer test,and International Knee Documentation Committee(IKDC)grading,KT2000 stability evaluation and Lysholm function score of knee joint were com-pared at 6 months after operation.Results All patients were followed up for 8 to 16 months with an average of(12.3±1.9)months.There were no complications such as incision infection,fracture malunion or non-union,and internal fixation loosening occurred.The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation.Operation time and blood loss in open reduction and internal fixation group were(56.4±7.1)min and(63.2±10.2)ml,while(89.9±7.4)min and(27.7±8.7)ml in arthroscopic fixation group,respectively,and had significant difference between two groups(P＜0.05).There were no differences in immediate reduction quality(x2=0.257,P=0.612),knee joint range of motion at 6 months after opertaion(t=0.492,P=0.626),knee joint rear drawer test(x2=0.320,P=0.572),IKDC classification of knee joint(x2=0.127,P=0.938),KT2000stability evaluation(x2=0.070,P=0.791),and knee Lysholmfunction score(t=0.092,P=0.282)between two groups.Conclusion Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixa-tion for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results,and arthroscopic surgery has less bleeding,but also has a longer learning curve and longer operation time than traditional inci-sion surgery.The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

Abstract: Objective To explore the trend of maternal mortality in Hainan Province during the period of 2003-2022, both in the province and in urban and rural areas, and to forecast the maternal mortality rate for the period 2023-2025. Methods The 2003-2022 data collected from Hainan Province's three-tier network for maternal mortality surveillance was examined using the Chi-square test for trend (CMH) to analyze the province-wide and urban-rural maternal mortality trends. The time series model forecasting using exponential smoothing was used to predict the maternal mortality rate in Hainan Province from 2023 to 2025. Results　From 2003 to 2022, a total of 201 011 616 live births and 463 maternal deaths were reported in Hainan Province, with a maternal mortality rate of 23.03 per 100 000. Over 20 years, the maternal mortality rate in Hainan Province showed a downward trend, with an annual rate of decline of -4.13%. The rate decreased significantly during this period.. From 2003 to 2022, the maternal mortality rate in rural areas of Hainan Province was 25.74/100 000 (373/1 448 943), and it was significantly higher than that in urban areas, 16.04/100 000 (90/561 173). In the first 10 years, the gap between urban and rural areas progressively reduced, but it widened significantly in the last decade, especially after 2017. The maternal mortality rate was significantly lower in urban than rural areas, and the differences had statistical significance. The annual rates of decline in maternal mortality in Hainan Province and in urban and rural areas from 2003 to 2022 were -5.0% and -3.71%, respectively, showing a negative growth with the decrease rate in rural areas lower than urban areas. The maternal mortality rate in Hainan Province showed a fluctuating downward trend, different from the stable trend of national decrease. The mortality rates for direct obstetric causes of death (233 cases) and indirect obstetric causes of death (230 cases) were 11.59/100 000 and 11.44/100 000, respectively. The results of the maternal mortality review showed a predominance of avoidable deaths (315 cases, 68.03%). Brown's cubic exponential smoothing predicted the maternal mortality rate in Hainan Province for 2023-2025 as 9.45/100 000, 8.17/100 000, and 6.89/100 000. Conclusions　The maternal mortality rate in Hainan Province is largely influenced by maternal deaths in rural areas, and maternal health care in rural areas should be emphasized. Measures such as intervening to address the main factors influencing avoidable maternal deaths, strengthening high-risk maternal management, improving the level of critical maternal care, and providing subsidies for critical maternal care can sustainably reduce the maternal mortality rate in Hainan.

Objective:To compare ocular surface dry eye-related indexes and tear cytokine level changes in chronic ocular graft-versus-host disease (oGVHD) patients after receiving topical treatment of 0.05% cyclosporine or 0.1% tacrolimus eye drops.Methods:A randomized controlled study was conducted.A total of 60 chronic oGVHD patients (60 eyes) were recruited at Beijing University Third Hospital from April 2020 to April 2021.The patients were divided into tacrolimus group and cyclosporine group by a random number table, with 30 patients (30 eyes) in each group.Patients in tacrolimus group used 0.1% tacrolimus eye drops (twice a day) and patients in cyclosporine group used 0.05% cyclosporine eye drops (4 times a day).Additionally, 0.1% flumetholon (twice a day), deproteinized calf blood extract (3 times a day), and 0.1% sodium hyaluronate eye drops (8 times a day) were applied for anti-inflammation and lubrication in both groups.Patients were screened according to exclusion criteria after 1-month treatment.Eventually, 21 patients (21 eyes) in tacrolimus group and 12 patients (12 eyes) in cyclosporine group were included for further study.Patients were examined before and 1 month after treatment.The primary evaluation indexes included Ocular Surface Disease Index (OSDI), corneal fluorescein staining scores and tear film break-up time (BUT).Expressions of interleukin (IL)-6, IL-8, IL-17, epidermal growth factor (EGF), and tumor necrosis factor-α (TNF-α) in tears were detected before and after treatment using Luminex chip.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Peking University Third Hospital (No.M2020489).Written informed consent was obtained from each subject before any medical examination.Results:The OSDI differences between before and after treatment were 0.4(-5.6, 2.5) in tacrolimus group and 27.2(4.6, 45.0) in cyclosporine group, and the OSDI improvement was significantly greater in cyclosporine group than in tacrolimus group ( Z=-2.547, P=0.009).The differences of corneal fluorescein staining scores and BUT between before and after treatment were 5.0(2.5, 10.0) scores and 3.5(-0.5, 13.8) seconds in tacrolimus group, 0.0(-3.0, 0.0) scores and -1.5(-3.0, 0.0) seconds in cyclosporine group, respectively, with no significantly difference between both groups ( Z=-0.526, -0.804; both at P>0.05).The differences of IL-6, IL-8, IL-17, EGF and TNF-α expressions between before and after treatment in tacrolimus group and cyclosporine group were not significantly different ( Z=-0.487, -0.112, -0.412, -1.085, -1.198; all at P>0.05). Conclusions:Altered levels of all tested cytokines in oGVHD tears are of no significant differences between tacrolimus and cyclos porine treatment.In addition, 0.05% cyclosporine eye drops may be more comfortable than 1% tacrolimus for chronic oGVHD patients.

Aim To explore the mechanism of cryptotanshinone (CTS) against non-small cell lung cancer (NSCLC) by using network pharmacology and bioinformatics methods. Methods Taking CTS as the research object, TCMSP database, SwissTargetPrediction and PharmMapper target prediction platform were used to collect CTS related targets; OMIM database, Gene-Cards data-base and TCGA database were employed to collect NSCLC related targets; String database and Cytoscape software were applied to construct PPI of intersection targets Network diagram, the hub targets were screened out, and AutoDock Vina was used for molecular docking verification; the R language clusterProfiler package was used to perform GO and KEGG enrichment analysis on the intersection targets; Cytoscape software was employed to construct the "CTS intersection targets-KEGG pathway" network. Results As a result, 75 intersecting targets were obtained, mainly involving various biological processes such as signal transduction, phosphorylation and dephosphorylation, apoptosis and vascular regulation, mainly through pancreatic cancer, colorectal cancer, cancer pathways and JAK-STAT signaling pathways. And cellular pathways such as apoptosis and natural killer cell-mediated cytotoxicity exerted their anti-NSCLC effects. Conclusions CTS exerts its anti-NSCLC effect through multiple targets and multiple pathways, which provides the theoretical support for further in-depth research.

Objective:To investigate the correlation between preeclampsia and thyroid dysfunction in pregnancy.Methods:107 early pregnant women with preeclampsia admitted to our hospital from Jan. 2017 to Jan. 2020 were all enrolled (observation group) . The observation group were in 6-34 gestational weeks, with an average parity of (1.67±0.35) times. In addition, 100 cases of normal pregnant women in the same period were selected as the control group. The control group were in 6-34 gestational weeks, with an average parity of (1.61±0.31) times. The two groups were compared at early, mid and late pregnancy in terms of thyroid function, and the correlation of preeclampsia and abnormal thyroid function was analyzed.Results:1. TSH levels in the observation group were (1.92±1.24) , (2.07±0.82) , and (2.30±1.23) mU/L in the first trimester, second trimester and third trimester, respectively, showing an upward trend. The difference between the two groups was statistically significant ( P=0.024) . FT4 levels of the observation group in the first trimester, second trimester and third trimester were (0.80±0.26) , (0.60±0.34) and (0.59±0.32) pmol/L, respectively, showing a decreased trend and the difference was statistically significant compared with those of the control group ( P=0.012) . 2. The incidence of hypothyroidism, TPOAb positive and reduced free tetraiodothyronine in the observation group was significantly higher than that in the control group ( P=0.001, 0.023, 0.005) . There was no significant difference in the incidence of hyperthyroidism or subclinical hypothyroidism between the two groups ( P=0.169, 0.846) . 3. Correlation analysis showed that preeclampsia was related to hypothyroidism, normal thyroid function with TPOAb positive and reduced free tetraiodothyronine ( P=0.000, 0.000, 0.000) . Conclusions:There are changes in thyroid function in pregnant women with preeclampsia. Hypothyroidism, positive TPOAb and reduced free tetraiodothyronine are closely related to the onset of preeclampsia.
