ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To determine the optimal irradiation energy and frequency for the establishment of melasma mouse model using simple ultraviolet irradiation, and to provide guidance on animal strains and irradiation protocols for the successful establishment of melasma model.Methods:Animal models of melasma were established using BALB/c female mice and C57BL/6JNifdc female mice. BALB/c female mice were divided into 4 groups using a simple randomization method: A, B, C and G, with 5 mice in each group. C57BL/6JNifdc female mice were divided into 4 groups: D, E, F and H, with 5 mice in each group. All mice were irradiated with 8.428 mW/cm 2 of ultraviolet light. The irradiation time was 15 s (single irradiation energy of 0.13 J/cm 2) in groups A and D, 15 min (single irradiation energy of 7.59 J/cm 2) in groups B and E, and 30 min (single irradiation energy of 15.17 J/cm 2) in groups C and F. Each cycle consisted of 5 consecutive days of irradiation followed by 2 days of cessation, totaling 4 cycles of irradiation. Groups G and H were not irradiated. At the end of irradiation, all mice were kept under normal conditions. One week later, 3 mice from each group were selected for HE, Masson-Fontana, Masson, and immunohistochemical staining. Quantitative analysis was performed to measure the thickness of the acanthocyte layer, melanin granules, collagen percentage, and interleukin-1 (IL-1) levels. The remaining mice were kept for an additional week, depilated and photographed to observe the changes in coloration. Data were analyzed using SPSS 27.0 software, measurement data that did not conform to normal distribution were represented by M( Q1, Q3) and comparisons between groups were made using the Kruskal-Wallis rank sum test. Results:During the entire irradiation process, no visible discoloration was observed in the BALB/c female mice in all groups. In contrast, varying sizes of discoloration appeared in the C57BL/6JNifdc female mice in groups D, E, and F after irradiation in the second week. However, by the third week, the discoloration in group D gradually disappeared, while the discoloration in group E was more obvious than before. At the same time, group F exhibited significant discoloration, with some mice exhibited signs of skin peeling, burning and breakage on their backs. After the 4th week of irradiation, no new discoloration was formed in group D. The discoloration was more obvious in group E, and most mice in group F showed skin burn breakage. Two weeks after the completion of irradiation, there was no obvious discoloration on the dorsal skin of BALB/c female mice in all groups. In C57BL/6JNifdc female mice, group D showed no obvious discoloration, group E exhibited lighter discoloration compared to the 4th week post-irradiation, and group F had crusted skin at the burn sites with lighter discoloration than before. However, the discoloration in groups E and F was still obviously visible to the naked eye. HE staining showed that the difference in the thickness of the echinocyte layer was not statistically significant in groups A, B, C, and G ( H=1.08, P=0.782); whereas the difference was statistically significant in groups D, E, F and H ( H=12.85, P=0.005). The thickness of the echinocyte layer decreased gradually with the extension of the irradiation time. Additionally, there was a disruption in the arrangement of epidermal spindles in group F, and this situation was not observed in groups D and E. Masson-Fontana staining revealed no significant pigmentation in any of the BALB/c female mice. The difference in melanin granule counts between groups A, B, C, and G was not statistically significant ( H=7.77, P=0.051). In contrast, C57BL/6JNifdc female mice exhibited more noticeable pigmentation in the epidermis and dermis in groups E and F. The difference in melanin particle counts among groups D, E, F and H was statistically significant ( H=17.61, P<0.001), with melanin deposition increasing gradually with the duration of irradiation. Masson staining showed that the difference in collagen percentage between groups A, B, C, and G was not statistically significant ( H=7.26, P=0.064). However, significant disorganization of fibers and a loose structure were observed in groups E and F. The difference in collagen percentage between groups D, E, F, and H was statistically significant ( H=8.65, P=0.034). Immunohistochemical results showed that the difference in IL-1 expression levels between groups A, B, C, and G was statistically significant ( H=17.86, P<0.001); also between groups D, E, F, and H was statistically significant ( H=14.19, P=0.003), suggesting that ultraviolet irradiation stimulated an inflammatory response in the skin of mice. Conclusion:BALB/c female mice are not suitable for melasma models under the frequency and duration of irradiation in this experiment. C57BL/6JNifdc female mice are irradiated with a single irradiation energy dose of 7.59 J/cm 2 five days a week for 4 weeks, which can establish stable animal models of melasma with a specific level of pigmentation that persisted for at least 2 weeks.

OBJECTIVE To establish the fingerprint and multi-component content determination method of Crataegus pinnatifida leaves from different producing areas， and to evaluate the quality of C. pinnatifida leaves and screen the differential markers. METHODS Seventy-eight batches of C. pinnatifida leaves were collected from Chengde of Hebei Province， Huludao of Liaoning Province， Yuncheng of Shanxi Province and Linyi of Shandong Province. High-performance liquid chromatography （HPLC） and Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprints （2012 edition） were used to draw the fingerprints and conduct similarity evaluation. Grey correlation analysis， cluster analysis （CA）， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were performed by using SPSS 19.0， MetaboAnalyst 5.0 and SIMCA 14.1 software. The differential markers affecting the quality of C. pinnatifida leaves were screened with variable importance in the projection （VIP） value greater than 1 and the error line not exceeding the origin as the criterion. Using vitexin rhamnoside as an internal reference， the contents of chlorogenic acid， glucosylvitexin， hypericin and isoquercetin in 78 batches of C. pinnatifida leaves were determined by the same HPLC combined with quantitative analysis of multi- components by single-marker （QAMS）， and the results were compared with external standard method. RESULTS Eight common peaks were calibrated in the fingerprints for 78 batches of C. pinnatifida leaves from 4 producing areas. Five known components were identified， including chlorogenic acid （peak 1）， glucosylvitexin （peak 3）， vitexin rhamnoside （peak 4）， hypericin （peak 7） and isoquercetin （peak 8）； their similarities ranged from 0.871 to 0.998. Average relative correlations of samples from Chengde of Hebei Province， Huludao of Liaoning Province， Yuncheng of Shanxi Province and Linyi of Shandong Province were 0.538， 0.528， 0.462 and 0.435， respectively. CA and PCA showed that the samples from Chengde of Hebei Province and Huludao of Liaoning Province were roughly classified into one category， while the samples from Linyi of Shandong Province and Yuncheng of Shanxi Province were roughly classified into one category； VIP values of peak 1， 2， 3 and 5 were all greater than 1. By QAMS， the relative correction factors of chlorogenic acid， glucosylvitexin， hypericin and isoquercetin were 0.401， 0.993， 1.670 and 1.615 （RSD＜2%）. Compared with external standard method， except for isoquercetin in the two batches of samples （S39 and S41）， there was no significant difference in the content of each component in other batches of samples （the relative deviations≤ 5%）. CONCLUSIONS The established fingerprint and QAMS method are simple to operate and can be used to evaluate the quality of C. pinnatifida leaves. The sample from Chengde of Hebei Province is relatively good in quality. Chlorogenic acid （peak 1）， glucosylvitexin （peak 3）， and the corresponding components of peaks 2 and 5 may be differential markers affecting the quality of C. pinnatifida leaves.

Age, male, family history of stroke, coronary heart disease, hypertension, diabetes mellitus, overweight/obesity are the risk factors of ischemic stroke in rural areas of Liaoning province.

OBJECTIVE: To review the development of adult and pediatric liver transplantation in Tianjin First Center Hospital, and to enhance academic exchanges, improve technological innovation, and jointly promote the progress and maturity in the field of liver transplantation. METHODS: The development of liver transplantation in Tianjin First Center Hospital was analyzed. The clinical data of adult and pediatric liver transplantation from September 1998 to September 2018 were collected. The important events and technological innovation achievements of liver transplantation during the 20 years were summarized. RESULTS: The first clinical liver transplantation was attempted in Tianjin First Central Hospital in April 1980. The first long-term survival adult liver transplantation in China was completed in 1994 (11 years survival after the operation). The specialized team of liver transplantation was formally established in September 1998. The 20-year clinical exploration and progress reflected the characteristics of era changes and technological innovation during the rapid development of liver transplantation in China. Our center performed liver re-transplantation in January 1999, reduced-size pediatric liver transplantation in August 2000. In May 2001, we organized the formulation for the preventive and treatment plan for hepatitis B recurrence after liver transplantation. We performed combined liver and kidney transplantation in July 2002, split liver transplantation (SLT) in April 2004, the first domino liver transplantation (DLT) in August 2005. Pediatric living donor liver transplantation (LDLT) was initiated in October 2006, adult LDLT was carried out in August 2007. In September 2007, the first living donor combined liver and kidney transplantation from the same donor in Asia was performed. The first domino+living donor double grafts liver transplantation in the world was performed in January 2009. In March 2011, we performed laparoscopically assisted right hepatic lobe liver transplantation (LDLT) with middle hepatic vein. In May 2014, living donor laparoscopic left lateral lobe procurement was successfully established. In April 2016, simultaneous liver, pancreas and kidney multi-organ transplantation was completed. Domino donor-auxiliary liver transplantation was performed in February 2017. In December 2017, extracorporeal membrane oxygenation (ECMO)-supported liver transplantation in a patient with severe pulmonary hypertension was successfully completed. Liver transplantation combined with partial splenectomy was established in April 2018. Cross-domino liver transplantation (hypersensitive kidney transplantation with auxiliary liver transplantation+pediatric liver transplantation) was performed in May 2018. During the 20 years, the team has performed or assisted other centers in Beijing, Shanghai, Guangzhou and Shenzhen to carry out more than 10 000 cases of liver transplantations. A total of 7 043 cases of various types of liver transplantation were performed in the single center of the hospital (6 005 adult liver transplantations and 1 038 pediatric liver transplantations). Concerning adult liver transplantation, the cumulative 1-year, 3-year and 5-year survival rate from September 1998 to March 2003 were 83.1%, 73.0% and 69.0%, from April 2003 to March 2009 were 85.3%, 76.2% and 72.1% and from April 2009 to September 2018 were 87.5%, 79.2% and 75.1%, respectively. The cumulative 1-year, 3-year and 5-year survival rate for pediatric liver transplantation were 93.5%, 92.2% and 90.2%, respectively. The nucleoside (acid) analogue combined with low dose hepatitis B immunoglobulin (HBIG) was developed to prevent the recurrence of hepatitis B after liver transplantation, this plan has reduced the recurrence rate of hepatitis B and the 5-year re-infection rate of hepatitis B virus (HBV) after liver transplantation significantly. The risk assessment system for tumor recurrence after liver transplantation was established and individual treatment method was established based on this assessment system. Continuous exploration and improvement of liver transplantation for liver cancer, liver re-transplantation, liver transplantation with portal vein thrombosis, SLT, DLT and multi-organ combined transplantation have significantly improved the clinical efficacy of patients and the post-operative survival rate. CONCLUSIONS The liver transplantation team of Tianjin First Center Hospital has carried out a scientific and technological exploration on the key problems and technical difficulties of clinical liver transplantation. This work strongly has initiated and promoted the rapid development of liver transplantation in China. The restrictive barrier of hepatitis B recurrence after liver transplantation has been overcome. The risk prevention and control system of tumor recurrence after liver transplantation has been established. A series of innovative achievements that can be popularized have been achieved in the field of complex liver transplantation and expansion of donor liver source. The iterative progress and sustainable development of liver transplantation have been realized.

This paper aimed at studying the physical and chemical properties, general examination and contents of someeffective components of Erratum Mongolia, and to provide scientific basis for the establishment of the quality standard ofvenerates Mongolia. The physical and chemical properties of venerates were identified by microscope and thin layerchromatography, and the general examination of venerates was studied with reference to the appendix of the 2010 editionof People's Republic of China Pharmacopoeia, and the main characteristic components and the active components inErratum were analyzed by HPLC. The content was analyzed and compared. The characters and microscopic identificationconfirmed that all the 7 batches of samples were venerates. The TLC identification was used as the control product ofhermitage, Erratum and restorative. The test products showed the same color spots in the corresponding position of thecontrol products. The spots were clear and the separation degree was good; the water and extracts of the different batch ofvenerates were examined by general terms. The content of ash in the Erratum collected from different regions was notsignificantly different (5.74-6.98％) . The content of the main active ingredients (hermitage) in Erratum from differentareas of the same plant is compared for the first time. The method is simple and reproducible. It provides a scientificbasis for improving the quality standard of Erratum Mongolia, the safe and rational application and the furtherdevelopment and production.

Objective To investigate the prevalence of depression in Parkinson's disease ( PD) patients, analyze the clinical features of depression in PD patients , and evaluate its impact on quality of life. Methods One hundred and ninety-five PD patients and 63 normol controls were recruited in this study.The detailed clinical information was documented.Unified Parkinson's Disease Rating Scale and Hoehn-Yahr stage were used to evaluate the severity of motor function impairment in PD patients.Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale were employed to assess the severity of depression and anxiety in PD patients.The 39-item Parkinson's Disease Questionnaire was applied to assess the quality of life.The cross-sectional data were calculated with SPSS 21.0 statistic software, and P ＜0.05 was considered statistically significant.Results The average score of HAMD was 8.74 ±5.51 in 195 PD patients.Depressive symptoms were found in 54.4%of the PD patients ( mild depression 48.7% and moderate depression 5.6%).Depression significantly impaired the quality of life in PD.Compared with PD without depression, PD with depression earned more scores in anxiety factor (4 (2, 5) vs 1(0, 2), Z＝ -8.69, P＝0.00), blocker factor (2 (1, 3) vs 0(0, 1), Z＝-7.95, P＝0.00), cognitive factor (1 (0, 2) vs 0(0, 0), Z＝-7.01, P＝0.00), sleep factor (2(1, 3) vs 0(0, 1), Z＝-6.42, P＝0.00) and despair factor (2 (1, 3) vs 1 (0, 1), Z＝-7.16, P＝0.00).There was no significant difference in day and night change (0(0, 0) vs 0(0, 0), Z＝-0.19, P＝0.85) and body weight (0(0, 0) vs 0(0, 0), Z＝-1.28, P＝0.20) between these two groups.The PD with depression obtained higher scores in total quality of life (30(22, 44) vs 14 (5, 24), Z＝-7.03, P＝0.00), motor function (6 (2, 13) vs 1 (0, 5), Z＝-3.67, P＝0.00), daily life ability (4 (1, 8) vs 1 (0, 4), Z＝-2.81, P＝0.01) , emotional health (5 (2, 11) vs 0 (0, 2), Z＝-5.82, P＝0.00), humiliation (2 (0, 5) vs 0 (0, 1), Z＝-3.10, P＝0.00), social support (0 (0, 1) vs 0 (0, 0), Z＝-2.86, P＝0.00), recognition function (4 (2, 6) vs 2 (0, 4), Z＝-2.87, P＝0.00), sociability(1(0, 3) vs 0(0, 1), Z＝-3.25, P＝0.00), and body pain (3 (1, 6) vs 1 (0, 2), Z＝-3.91, P＝0.00) than patients without depression.Conclusions Incidence of depression ( mainly mild ) in PD patients is high. Depressive symptoms significantly affect the quality of life of PD patients.
