OBJECTIVE To observe the efficacy of cetrorelix combined with aspirin in preventing early-onset ovarian hyperstimulation syndrome （OHSS）. METHODS A retrospective analysis was conducted on clinical data from 38 early-onset OHSS patients， who received treatment in our hospital from January 1st to July 1st， 2022. These patients were divided into intervention group （19 cases） and control group （19 cases） according to the therapy regimen. On the first day after oocyte retrieval surgery， the control group was given aspirin enteric-coated tablets 100 mg orally until menstruation began. The intervention group was given cetrorelix for injection 0.25 mg subcutaneously， for consecutive 3 days+aspirin enteric-coated tablets （same usage and dosage as the control group）. The first luteal phase， the degree of OHSS， and the ovarian volume， ascites volume， serum estradiol （E2）， white blood cell count （WBC）， hematocrit （HCT）， neutrophil ratio （NEUT%）， D-dimer （DD）， prothrombin time （PT）， fibrinogen （Fib） after oocyte retrieval surgery were observed and measured in 2 groups. RESULTS The first luteal phase was significantly shorter， and the proportions of median and severe OHSS cases were significantly lower in the intervention group compared to the control group （P＜0.05 or P＜0.01）. After oocyte retrieval surgery， the intervention group showed significantly lower ovarian volume， ascites volume， serum E2， WBC， NEUT%， HCT， DD and Fib compared to the control group， but PT of intervention group was signiticantly higher than that of control group （P＜0.05）. CONCLUSIONS Cetrorelix combined with aspirin is more effective in preventing early-onset OHSS than aspirin alone.

Objective:To understand the current status of gastroscopy in diagnosing gastric lesions in general population, and to recommend the optimal age for the first gastroscopy and intervals for repeated gastroscopy.Methods:The gastroscopy records of residents aged 18-80 years in Yinzhou District of Ningbo, Zhejiang Province, between April 2010 and December 2021 were analyzed retrospectively. The detections of gastric lesions across different years, age and genders were described. Goodness of fit tests were applied to compare the differences in detection rates of different lesions in first-time endoscopy in different age groups and different populations. Generalized additive models were used to fit the trend of age specific gastric lesion detection rate explore the optimal age for gastroscopy. The appropriate gastroscopy intervals were determined according to the progress of the gastric lesions detected in repeated gastroscopy.Results:A total of 237 751 participants with 344 398 gastroscopy records were included in analyses. A total of 5 597 cases of chronic atrophic gastritis (CAG), 9 796 cases of intestinal metaplasia (IM), 165 cases of low-grade intraepithelial neoplasia (LGIN), 52 cases of high-grade intraepithelial neoplasia (HGIN) and 435 cases of gastric cancer were detected by the first gastroscopy. The overall detection rate of gastric lesions increased significantly in age group 45-70 years, and remained stable after 70 years old, with LGIN and HGIN showing notable increases at 50 and 55 years old, respectively. Repeated gastroscopy detected CAG, IM, LGIN, and HGIN at a higher rate compared with the first gastroscopy. Normal/superficial gastritis progressed in 3-5 years, whereas CAG or more severe lesions progressed in 1-6 years.Conclusion:Gastroscopy is recommended for general population aged 45 years and above. Furthermore, gastroscopy can be performed every 3-5 years for individuals with normal endoscopy results and once a year for patients with CAG or more severe gastric lesions.

Objective To investigate the mechanism of Yes-associated protein 1(YAP1)ameliorating aristolochic acid 1(AAI)-induced liver injury in mice based on untargeted metabolomics techniques.Methods There were 83-week-old male hepatocyte-specific Yap1 gene knockout mice(genotyped as Yap1Flox/Flox,Albumin-Cre,aka.Yap1LKO)were randomly selected as the Yap1LKO+AAI group,and 8 Yap1Flox control mice as the Yap1Flox+AAI group.Both groups were injected intraperitoneally with AAI at a dose of 2.5 mg·kg-1·d-1 for 14 consecutive days.Genotypes were identified by tail PCR;serum alanine transaminase(ALT)and aspartate transaminase(AST)activities were determined by microplate assay;histopathological changes of liver tissue were observed by HE staining;and the protein expression of YAP1 in liver tissue was determined by immunohistochemistry.The untargeted metabolomics approach was used to analyze the liver tissue differential metabolites,and the samples were analyzed by ultra performance liquid chromatography-quadrupole-electrostatic field orbit trap high-resolution mass spectrometry,and the differential metabolites were screened by principal component analysis(PCA),Partial least square-discriminant analysis(PLS-DA),and orthogonal partial least squares-discriminant analysis(OPLS-DA);using HMDB database and METLIN database to identify metabolites,and the pathway enrichment of differential metabolites was analyzed by KEGG database.Results(1)After 14 days of AAI induction,the increase of body mass in Yap1LKO mice was lower than that in Yap1Flox mice,but there was no statistical significance(P＞0.05).On day 14,compared with the Yap1Flox+AAI group,the serum ALT and AST enzyme activities in the Yap1LKO+AAI group of mice were significantly increased(P＜0.05),and the histopathological damage of the liver was significantly aggravated.The livers of the Yap1Flox mice had a positive protein expression of YAP1,whereas the Yap1LKO mice did not have a positive protein expression of YAP1.(2)A total of 139 differential metabolites with significant changes(VIP＞1 and P＜0.05)were screened by metabonomic analysis;compared with Yap1LKO+ AAI group,62 liver metabolites in Yap1Flox+AAI group were up-regulated,including choline,taurine,hypotaurine,α-linolenic acid,eleostearic acid,chenodeoxycholic acid and so on.Seventy-seven metabolites were down-regulated including glycerophosphocholine,L-phosphatidylcholine,L-glutamine,L-serine,L-glutathione,5-methionine,phenylalanine,glucose 6-phosphate,lactic acid,uric acid glycosides,etc..KEGG-enriched pathways were mainly choline metabolism,glycerophospholipid metabolism,insulin resistance,glutathione metabolism,etc..Conclusion Hepatocyte-specific Yap1 gene knockout exacerbated AAI-induced liver injury in mice,and YAP1 was involved in the regulation of choline metabolism and glycerophospholipid metabolism through the up-regulation of unsaturated fatty acids,such as choline and taurine,which ameliorated AAI-induced liver injury in mice.

Objective　To timely understand the current status and distribution of nail snails (Oncomelania hupensis) in Tongjiang River channels in Zhenjiang City, providing a scientific basis for achieving the goal of eliminating schistosomiasis. Methods　From 2019 to 2023, nine Tongjiang River channels on the south bank of the Yangtze River under the jurisdiction of Zhenjiang City were selected as the monitoring area. Snail monitoring was carried out onshore and beach nail snails floats in the Tongjiang River channels, nail snails on attachments in hardened areas, snails induced by straw curtains, and snails carried by boats and domestic animals. Results　The monitoring results of shoreline snail from 2019 to 2023 showed that the snail situation in the Tongjiang River channel and its outer river bank remained relatively stable from 2019 to 2020; however, in 2021, under the influence of the Yangtze River flooding disaster in 2020, the area of snails increased significantly. In 2021, the area with snails in the Tongjiang River channel and the outer river bank increased by 45.70% (11.95/26.15) and 100.00% (20.00/20.00) compared to 2020; the average density of nails snails in the Tongjiang River channel and the outer river bank and the emergence rate of snail frames both showed a significant increase, rising by 94.73% (0.18/0.19) and 68.08% (8.68/12.75) compared to 2020, and by 122.73% (0.81/0.66) and 102.78% (43.26/42.09), respectively. The differences in the increase in the occurrence rate of spiked frames in the Tongjiang River channel Chili River and Renmin River were not statistically significant (χ2=0.329, P>0.05; χ2=0.646, P>0.05). From 2022 to 2023, the density of nail snails and the occurrence rate of framed snails in the Tongjiang River channel showed a decreasing trend (F=4.72, P=0.04 and χ2=372.58, P<0.01). The area of nail snails, density of live snails, and occurrence rate of framed snails in the outer river bank showed a decreasing trend (F=13.96, P=0.02; F=23.43, P<0.01; χ2=1 029.69, P<0.01). During the five years, no nail snails were detected in the ancient canal and 11 tributaries. From 2019 to 2023, 180 times of 3 003 kg of floating objects were salvaged, with a total of 148 live snails detected. A total of 17 live snails were captured on attachments in the hardened berm area; a total of 11 live snails were captured by straw curtain snail baiting;112 boats were inspected, and no snails were found; there were 112 boats surveyed, and no snails were found; 97 cattle were observed, and 2 cattle were found to carry 1 live snail on their hooves; 321 sheep were observed, and no snails were found on their hooves; and no infectious snails were found in the monitoring area in 5 years. Conclusions　Nail snails continue to exist in the Tongjiang River channel, and the risk factors for schistosomiasis transmission have not been completely eliminated. It is still necessary to carry out accurate monitoring of the snail situation in the Tongjiang River and the river bank, so as to grasp the risk of transmission in time and take emergency measures.

【Objective】 To investigate the status quo of disease perception and partner support of erectile dysfunction (ED) patients, and to analyze their correlation. 【Methods】 With convenient sampling method, 220 ED patients in a first-class hospital in Taiyuan were surveyed with the short version of disease perception questionnaire (BIPQ) and partner support coping questionnaire (DCI). 【Results】 The BIPQ score was (41.90±7.33), and the DCI score was (116.79±20.37). Pearson correlation analysis showed that except life influence, treatment control and emotional influence, the mutual support dimension of partner support of ED patients was correlated with all dimensions of disease perception (r=-0.173, 0.151, -0.182, 0.163, 0.188,P<0.05).Except cognitive comprehension, the negative support dimension of partner support of ED patients was correlated with the dimensions and total score of disease perception (r=0.399, 0.185, -0.167, -0.306, 0.269, 0.445, 0.320, 0.357,P<0.05). 【Conclusion】 ED patients have negative disease perception, and their partners have better coping strategies. Medical staff may pay more attention to partner support so as to reduce patients’ negative perception of disease and promote recovery.

Objective:To analyze the clinic effects of arthroscopic partial trapeziectomy and suture button suspensionplasty in the treatment of first carpometacarpal joint (CMCJ) Eaton stage II/III arthrosis.Methods:A retrospective study was conducted on a total of 15 cases (16 hands) of patients including 5 males (1 bilateral) and 10 females with CMCJ stage II/III arthrosis who underwent surgical treatment at the first affiliated hospital of Shenzhen university from January 2020 to June 2022, with mean age of 56.7±6.4 years (range, 46-75 years). The duration from pain to treatment was 7.8±3.2 months (range, 4-14 months). X-ray showed narrowing of CMCJ with osteophytes and distal radial subluxation. All the patients were treated with arthroscopic partial trapeziectomy and suture button suspensionplasty. The preoperative and last postoperative follow-up radiographs, visual analogue scale (VAS), thumb's Kapandji scores, disabilies of the arm, shoulder, and hand (DASH) scores, grip and pinch strength and time to return to work were compared.Results:All cases were followed up for 19.6±6.3 months (range, 11-36 months). The postoperative X-ray showed all the CMCJs were reduced with a normal height of first metacarpal. The mean time for patients to return to their daily activities was 18.69±3.70 d and the mean time to return to work was 24.63±4.91 d. The average VAS score decreased from 6.56±1.15 preoperatively to 1.00 (0.75, 1.25). The preoperative Kapandji's score was 8.00±0.82 and the postoperative Kapandji's score was 8.00 (7.25, 9.00). The average DASH values improved from 24.06±3.19 to 4.00 (3.00, 5.00). The were significant differences except for Kapandji score ( Z=-4.905, P<0.001; Z=-0.121, P=0.905; Z=-4.846, P<0.001). The mean grip and pinch strength showed improvement from an average of 16.4 (14.13, 18.68) kg and 1.70±0.35 kg to 26.14±3.27 kg and 3.58±0.91 kg with significant difference ( Z=-4.617, P<0.001; t=-7.669, P<0.001). Conclusion:Arthroscopic partial trapeziectomy and suture button suspensionplasty is a minimally invasive surgery for the treatment of first CMCJ Eaton stage II/III arthrosis. By this technique, the patients' existing instability and pain problems can be solved.

ObjectiveTo investigate the material basis of homologous and heterogeneous effect of Aurantii Fructus Immaturus（AFI） and Aurantii Fructus（AF） based on the total statistical moment analysis and molecular connectivity index（MCI）. MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） were consulted to establish the chemical composition database of AFI and AF， and set up their fingerprints by ultra-high performance liquid chromatography（UPLC）， and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI， all components of AFI and AF were divided into different component groups， the average values of 0-8^th order（⁰χ-⁸χ） MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment（AUC_T） of AFI and AF were （10.57±2.45）×10⁶， （5.09±0.89）×10⁶ μV·s， the values of total first-order moment（MCRT_T） were （11.57±1.58）， （12.10±1.29） min， the values of total second-order moments（VCRT_T） were（24.49±2.30）， （26.49±2.54） min²， respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin， hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI， such as alysifolinone and imperatorin， and the non-common components of AF， such as neoeriocitrin and isosakuranin， with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories， and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997， the average values of ⁰χ-⁸χ MCI of alkaloids in AFI and AF were 3.65 and 3.14， the average values of ⁰χ-⁸χ MCI of flavonoids were 8.47 and 8.47， the average values of ⁰χ-⁸χ MCI of volatile oils were 2.71 and 3.48， respectively. It showed that there were some differences in MCI of chemical constituents（groups） between AFI and AF. ConclusionThe chemical constituents（groups） of AFI and AF not only differ in content and species， but also in structural characteristics and structure-activity relationship， which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

Objective:To explore the value of serum matrix metalloproteinase-1 (matrix metalloproteinase-1), and phosphatase and tensin hmmlogydeleted on ten (PTEN), in predicting osteoporosis (OP) in women with gestational diabetes mellitus (GDM) .Methods:The clinical data of.218 pregnant women with GDM treated in Linyi People’s Hospital from Sep. 2019 to Feb. 2023 were retrospectively collected and included in the GDM group. Another 98 healthy pregnant women who underwent physical examination during the same period were selected as the control group. Age, body mass index (BMI), blood glucose related indexes and serum MMP-1 and PTEN levels were compared between the two groups. According to the occurrence of osteoporosis (OP) in the second and third trimester of pregnancy, the GDM group was divided into OP group and non-OP group. Logistic regression analysis was used to explore the influencing factors of OP in pregnant women with GDM in the second and third trimesters. ROC curve was drawn to analyze the predictive value of serum MMP-1 and PTEN levels for osteoporosis in GDM pregnant women in the second and third trimesters.Results:Body mass index (BMI), fasting blood glucose (FBG), glycated hemoglobin A1c (HbA1c) and serum MMP-1 and PTEN levels in GDM group were higher than those in control group, but BUA, SOS and SI were lower than those in control group ( t=6.18, 12.68, 9.91, 11.42, 7.70, 5.63, 5.76, 9.84, all P<0.05). Among 218 GDM women, 29 cases had OP and 189 cases did not have OP. There were no significant differences in fasting blood glucose, glycosylated hemoglobin, blood calcium, blood magnesium, or blood phosphorus between the two groups (statistical value: 0.96, 0.86, 1.35, 1.06, 0.49, P>0.05). Logistic regression analysis showed that age, abnormal increase of MMP-1 and PTEN levels were independent risk factors for OP in GDM women in the second and third trimesters [ OR (95% CI) =1.260 (1.103-1.440) ,1.075 (1.031-1.120) ,1.055 (1.023-1.089), all P<0.05]. ROC curve showed that the AUC of MMP-1 and PTEN in predicting OP in GDM pregnant women in the second and third trimesters were 0.824 and 0.777, respectively. The AUC of the combination of the two in predicting OP in GDM pregnant women in the second and third trimesters was 0.933, and the specificity and sensitivity were 83.04% and 93.48%, respectively, which were higher than those of single detection. Conclusions:MMP-1 and PTEN in early pregnancy may play a potential role in the prediction of OP in pregnant women with GDM. Close monitoring of MMP-1 and PTEN levels may provide new ideas for the clinical diagnosis and treatment of OP high-risk patients.
