Objective To explore the application of the Autoregressive Integrated Moving Average (ARIMA) model in predicting the number of reported hepatitis E cases in Yunnan Province，to use this model to predict the incidence trend of hepatitis E, and to provide reference for the scientific prevention and control of hepatitis E. Methods Monthly reported cases of hepatitis E in Yunnan Province from 2012 to 2021 were collected. The ARIMA model was established using SPSS 27.0, and the model was validated and parameters were optimized with data from January 2022 to December 2022. The optimal fitting model was used to predict the incidence of hepatitis E in 2023. Results Hepatitis E incidence in Yunnan Province showed a certain seasonal distribution, with most cases concentrated from March to August. All parameters of ARIMA(3,1,4)(1,1,1)₁₂ passed statistical tests. The Ljung-Box test showed statistic Q =10.050, P = 0.346, residual sequence was a white noise sequence, and goodness-of-fit index stationary R² was 0.591. The model extrapolation effect was verified with 2022 data, and MAPE was 14.747, indicating that the model extrapolation effect was effective. The number of hepatitis E cases in Yunnan Province in 2023 was expected to be 1,086. Conclusion The ARIMA (3,1,4)(1,1,1)₁₂ model shows good fitting performance for hepatitis E cases in Yunnan Province and can effectively predict short-term disease trends, providing a theoretical basis for formulating prevention and control measures for hepatitis E.

Objective To investigate the effect of acupuncture on the morphology of the dry eye rabbit's cornea and the nuclear factor κB(NF-κB)signaling pathway of the corneal tissue to analyze the mechanism of acupuncture on dry eyes.Methods Twenty-four healthy New Zealand rabbits,without restriction on sex,were randomly divided into four groups,including a blank group,a model group,an acupuncture group,and a sham acupuncture group,with 6 in each group.Rabbits in the blank group were not treated;rabbits in the other three groups were treated with scopolamine hydro-bromide 2.0 mg·kg-1 by subcutaneous injection at 8:00,11:00,14:00 and 18:00 each day for 35 consecutive days un-til the end of the experiment.Rabbits in the sham acupuncture group were treated with sham acupuncture on the 22nd day after successful modeling by quickly pricking acupoints(Jingming BL1,Cuanzhu BL2,Sizhukong SJ23,Taiyang EX-HN5 and Tongziliao GB1)with a blunt acupuncture needle,once a day,for a total of 14 days.Rabbits in the acupuncture group were treated with acupuncture at the same acupoints as the sham acupuncture group after successful modeling.The corneal fluorescence staining was conducted on Days 0,21,28 and 35 after modeling.On Day 35,corneal confocal microscope ex-aminations were conducted.Then,the rabbits were sacrificed,the corneal morphological changes were observed by light microscope and transmission electron microscope,and the expression of corneal NF-κB protein was detected by Western blot.Results Compared with the model group,the score of rabbit corneal fluorescein staining in the acupuncture group and blank group decreased on the 28th and 35th days after modeling,and the differences were statistically significant(all P＜0.05).The results of the confocal microscope examination on Day 35 after modeling showed that,compared with other groups,there were a large number of globular immune cells and activated stromal cells with unclear boundaries and irregu-lar sizes in the stromal layer and inflammation in the area with irregular intercellular space in the model group and the sham acupuncture group.In the acupuncture group,the morphology of stromal layer cells improved,the cells were slightly acti-vated,and there were no obvious abnormalities in the corneal nerve morphology.On the 35th day after modeling,the re-sults of the light microscope showed that,the surface of the corneal tissue in the model group and the sham acupuncture group showed hyperkeratinized flat epithelial cells,lymphocyte infiltration,increased number of focal epithelial cell layers,and epithelial cell detachment.In the acupuncture group,there were 4-6 layers of epithelial cells in the corneal epitheli-um,and epithelial shedding decreased.In addition,the lymphocyte infiltration decreased compared with the model group.On the 35th day after modeling,the results of the transmission electron microscope showed that abnormal microvilli oc-curred and epithelial cells were absent in the corneal epithelial cells of rabbits in the model group and the sham acupuncture group,the cell space was widened,the rough endoplasmic reticulum was severely expanded,and desmosomes were dis-banded with mitochondrial swelling.In the acupuncture group,the microvilli structure of epithelial cells was sparse and short,local deletion was still observed,the rough endoplasmic reticulum was slightly expanded,and no obvious swelling of mitochondria was observed.On the 35th day after modeling,the Western blot examination results showed that,compared with the blank group,the expression of p-NF-κB p65 was up-regulated in both the model group and sham acupuncture group(both P＜0.05);compared with the model group and sham acupuncture group,the expression of p-NF-κB p65 in the acupuncture group was down-regulated(both P＜0.05).Conclusion Acupuncture can inhibit the NF-κB signaling path-way to play an anti-inflammatory role and relieve corneal inflammation and injury of dry eye rabbit models.

Background/Aims: Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is widely accepted as a radical surgery for refractory ulcerative colitis (UC). Definite results on the appropriate pouch length for an evaluation of the risk-to-benefit ratio regarding technical complications and long-term quality of life (QOL) are still scarce. Methods: Data on UC patients who underwent IPAA from 2008 to 2022 in four well-established pouch centers affiliated to China UC Pouch Center Union were collected. Results: A total of 208 patients with a median follow-up time of 6.0 years (interquartile range, 2.3 to 9.0 years) were enrolled. The median lengths of the patients’ short and long pouches were 14.0 cm (interquartile range, 14.0 to 15.0 cm) and 22.0 cm (interquartile range, 20.0 to 24.0 cm), respectively. Patients with a short J pouch configuration were less likely to achieve significantly improved long-term QOL (p=0.015) and were prone to develop late postoperative complications (p=0.042), such as increased defecation frequency (p=0.003) and pouchitis (p=0.035). A short ileal pouch was an independent risk factor for the development of late postoperative complications (odds ratio, 3.100; 95% confidence interval, 1.519 to 6.329; p=0.002) and impaired longterm QOL improvement (odds ratio, 2.221; 95% confidence interval, 1.218 to 4.050, p=0.009). Conclusions The length of the J pouch was associated with the improvement in long-term QOL and the development of late post-IPAA complications. A long J pouch configuration could be a considerable surgical option for pouch construction.

As confusion mounts over RNA isoforms involved in phenotypic plasticity, aberrant CpG methylation-mediated disruption of alternative splicing is increasingly recognized as a driver of intratumor heterogeneity (ITH). Protease serine 3 (PRSS3), possessing four splice variants (PRSS3-SVs; PRSS3-V1-V4), is an indispensable trypsin that shows paradoxical effects on cancer development. Here, we found that PRSS3 transcripts and their isoforms were divergently expressed in lung cancer, exhibiting opposing functions and clinical outcomes, namely, oncogenic PRSS3-V1 and PRSS3-V2 versus tumor-suppressive PRSS3-V3, by targeting different downstream genes. We identified an intragenic CpG island (iCpGI) in PRSS3. Hypermethylation of iCpGI was mediated by UHRF1/DNMT1 complex interference with the binding of myeloid zinc finger 1 (MZF1) to regulate PRSS3 transcription. The garlic-derived compound diallyl trisulfide cooperated with 5-aza-2'-deoxycytidine to exert antitumor effects in lung adenocarcinoma cells through site-specific iCpGI demethylation specifically allowing MZF1 to upregulate PRSS3-V3 expression. Epigenetic silencing of PRSS3-V3 via iCpGI methylation (iCpGIm) in BALF and tumor tissues was associated with early clinical progression in patients with lung cancer but not in those with squamous cell carcinoma or inflammatory disease. Thus, UHRF1/DNMT1-MZF1 axis-modulated site-specific iCpGIm regulates divergent expression of PRSS3-SVs, conferring nongenetic functional ITH, with implications for early detection of lung cancer and targeted therapies.

In recent years, everyone has been working on exploring the physical properties of various energy platforms, especially lasers, to maximize their advantages in clinical use, various surgical concepts and methods contend. This article summarized my 40 years of experience in transurethral laparoscopic surgery to discuss my experience and thoughts.

【Objective】 To investigate the risk factors and predictive effectiveness of prostate imaging reporting and data system (PI-RADS) score for patients with clinically significant prostate cancer (CsPCa) whose PI-RADS score was 3, so as to provide evidence for the diagnosis and treatment. 【Methods】 The clinical and multi-parameter magnetic resonance imaging (mpMRI) data of 153 CsPCa patients treated during Jan.2017 and Dec.2021 whose PI-RADS score was 3 were retrospectively analyzed. With PI-RADS score of 3 as the independent risk factor for CsPCa, the other relevant independent risk factors in predicting CsPCa were evaluated. 【Results】 Univariate and multivariate analyses showed that prostate-specific antigen (PSA) density and apparent dispersion coefficient (ADC) were independent risk factors for the diagnosis of CsPCa (P<0.05). Analysis of receiver operating characteristic (ROC) curve showed that combined PSA density and ADC were more effective than PSA density and ADC alone (P<0.05). 【Conclusion】 The combination of PSA density and ADC can guide clinicians to identify high-risk CsPCa patients from patients with PI-RADS score of 3 points.

Hepatolithiasis is a common biliary tract disease in China and other Asian countries.It has insidious onset,recurrent disease,and may lead to biliary cirrhosis or even cancer in the late stage without inter-vention.At present,surgery is considered to be the best choice for treatment.In the 21st century of minimally inva-sive surgery,traditional procedures such as partial hepatectomy,choledochotomy,cholangioenterostomy and liver transplantation can be performed with the assistance of laparoscopy and da Vinci robots,and emerging endoscopic techniques such as endoscopic retrograde cholangiopancreatography(ERCP)and percutaneous transhepatic cho-ledochoscopic lithotripsy(PTCSL)have also been developed,bringing better treatment for patients with hepatoli-thiasis.As treatment options are becoming more varied,there are also some clinical problems that need to be addressed.In this article,we would like to briefly review the current surgical treatment modalities in order to provide a theoretical basis for optimizing the treatment modalities.

Four unreported monoterpene indole alkaloids, tabernaecorymines B-E (1-4), together with twenty-one known indole alkaloids (5-25) were obtained from the stem bark of Tabernaemontana corymbosa. Their structures and absolute configurations were elucidated by extensive spectroscopy, quantum chemical calculations, DP4+ probability analyses and Mo₂(OAc)₄-induced electronic circular dichroism experiment. The antibacterial and antifungal activities of these compounds were evaluated and some of them showed significant activity against Staphylococcus aureus,Bacillus subtilis, Streptococcus dysgalactiae and Candida albicans.

Objective:To discuss the effect of modified ultrafiltration combined with sequential infusion of blood products, such as platelets and cryoprecipitation, on perioperative coagulation function in neonates undergoing cardiovascular surgery under extracorporeal circulation.Methods:A retrospective analysis was performed on 83 neonates who underwent cardiovascular surgery from January 2017 to December 2019. They were divided into the control group (conventional ultrafiltration, 51 cases) and the treatment group (modified ultrafiltration + sequential infusion of blood products, 32 cases).Results:The age of treatment group was significantly younger than that of the control group ( P<0.05). The extracorporeal circulation time of the treatment group was significantly longer than that of the control group. Compared with the preoperative data, post-APTT, post-PT and post-INR were increased significantly in the control group, platelet count and FIB were decreased significantly ( P<0.01), while there was no significant difference in the treatment group. Compared with the treatment groups, post-APTT, post-PT and post-INR were significantly increased in the control group, and postoperative platelet count and FIB were significantly decreased ( P<0.05). The drainage of control group was significantly higher than that of the treatment group at 12 h and 24 h after surgery ( P<0.01). Conclusion:The application of modified ultrafiltration combined with sequential infusion of blood products can significantly improve perioperative coagulation and reduce mediastinal bleeding in neonatal after cardiovascular surgery.
