"State-target medicine" is a traditional Chinese medicine （TCM） diagnosis and treatment theoretical system proposed by Academician Tong Xiaolin based on the current development of modern medicine. The active stage of gastric ulcer， as a precancerous state of gastric cancer， has a great impact on people's health. Prof. ZHOU Xuewen， a master of TCM， innovatively put forward the theory of "toxicity-heat" etiology for the active stage of gastric ulcer， which plays an important guiding role in clinical diagnosis and treatment. The article took the theoretical system of "state-target medicine" as the framework to explain the rationale， method， formula， and medicine of Prof. ZHOU Xuewen， who applied the Xiaoyong Kuidekang based on the "toxicity-heat" theory to treat the gastric ulcer in the active stage. The Chinese medical name of gastric ulcer， "gastric carbuncle"， was established， and it was believed that gastric ulcer is born due to "toxicity" and is based on "toxicity and heat". In the course of the disease， "toxicity"， "heat"， "deficiency"， and "stasis" coexisted， and its pathogenesis was divided into three phases， namely， toxicity-heat accumulation phase， toxicity-heat affecting the health phase， and weakened body resistance and strengthened toxicity phase. According to the positioning of gastric ulcer as an "internal carbuncle"， Prof. ZHOU Xuewen proposed the treatment of gastric ulcer in the active stage with "carbuncle theory" and introduced the surgical methods of "elimination"， "support"， and "tonifying" into the treatment of gastric ulcer in the active stage. Prof. ZHOU Xuewen took "clearing heat and removing toxins， eliminating carbuncle and generating muscle" as the basic treatment of the disease. For different stages of the disease， Prof. ZHOU Xuewen emphasized the use of the methods of clearing heat and removing toxins， supporting rot and muscle growth， and strengthening the spleen and harmonizing the stomach and created the representative formula for the treatment of gastric ulcer in the active stage with "carbuncle theory"， namely "Xiaoyong Kuidekang"， which could regulate state and targets.

【Objective】 To explore the effect of autologous platelet-rich plasma(PRP) in the treatment of dry eye syndrome. 【Methods】 A total of 64 patients with dry eye treated in the Ophthalmology Department of Jingdong Sino-American Hospital of Hebei Province from March to November 2023 were randomly selected for the study. The patients were divided into observation group and control group according to the random number table method, with 32 cases and 64 eyes in each group. The control group was treated with artificial tears of polyvinyl alcohol without preservatives, and the observation group was treated with PRP eye drops. The clinical efficacy and adverse reactions of the two groups were compared. Overall efficacy, duration of symptom resolution, ocular surface disease index (OSDI), tear film break up time (TBUT), schirmer's test(St) and corneal fluorescein staining (CFS) results of the two groups were observed and compared in 4 weeks. 【Results】 After 4 weeks of treatment, the total effective rate of observation group was 96.88%(31/32), which was significantly higher than that of control group 84.38%(27/32), with statistical significance (P<0.05). After treatment, the St, TBUT, CFS, OSDI and lacrimal river height in observation group were significantly superior to control group, with statistical significance (P<0.05). The disappearance time of dryness, visual fatigue and foreign body sensation in the observation group was shorter than that in the control group, and the difference was statistically significant (P<0.05). The incidence of adverse reactions in the observation group was 46.875%(15/32), and there was no significant difference between the observation group and the control group. 【Conclusion】 Autologous PRP is an effective and safe choice for the treatment of dry eye syndrome, which is worthy of further study and confirmation.

Kidney transplantation is the first choice for treating uremia.Traditional cardiovascular risk factors,renal insufficiency related changes and immunosuppressive medications increase the risk of left ventricular insufficiency after kidney transplantation.Early identification and timely intervention of left ventricular dysfunction after kidney transplantation are helpful to improve life quality and survival time of the transplant recipients.The application progresses of various echocardiographic techniques in monitoring structural and functional changes of left ventricle after kidney transplantation were reviewed in this article.

Objective To investigate the clinical effect of transhepatic arterial chemoembolization(TACE)combined with tyrosine kinase inhibitors(TKIs)and programmed death receptors-1(PD-1)inhibitors(TACE+TKIs+PD-1 antibody)in the treatment of moderate advanced unresectable hepatocellular carcinoma(HCC).Methods The clinical data of 65 patients with moderate advanced unresectable hepatocellular carcinoma admitted to the Affiliated Hospital of North Sichuan Medical College from January 2020 to January 2022 were analyzed retrospectively.65 patients were treated with TACE+TKIs+PD-1 antibody.The observation indexes were tumor response,objective response rate(ORR),disease control rate(DCR),total survival time,progression free survival time,conversion operation rate and adverse drug reaction.Results The ORR of 65 p-atients with hepatocellular carcinoma was 49.2％(32/65),and the DCR was 89.2％(58/65).Among them,there were 2 patients with complete remission(CR),30 patients with partial remission(PR),26 patients with stable disease(SD),and 7 patients with progression disease(PD).Among 65 patients with hepatocellular carcinoma,18 patients were transformed into resectable hepatocell-ular carcinoma and underwent RO surgery.The conversion rate was 27.6％(18/65).65 patients were followed up for 3 to 22.4 months,The median follow-up time was 16.5 months.The median overall survival time and median disease progression free survival time of 65 patients were 14.5 months(95％CI:12.3～16.6 months)and 8.8 months(95％CI:6.9～10.6 months),respectively.After treatment,65 patients all had post embolism syndrome(abdominal pain,fever,nausea,vomiting and other symptoms),and some patients had transient abnormal liver function.Adverse drug reactions below grade 3 recovered within a few days.Some patients were associated with multiple adverse drug reactions.1 patient(1.5％)stopped using TACE because of stubborn vomiting,and 5 patients(7.6％)stopped using Lenvatinib because of severe liver function damage during treatment,2 patients(3％)stopped using Camrelizumab because of severe reactive capillary hyperplasia,one patient(1.5％)stopped using Tislelizumab because of severe hypothyroidism,one patient(1.5％)stopped the treatment of Lenvatinib and Sintilimab due to severe gastrointestinal bleeding.The adverse drug reactions of grade 3～4 occurred in other patients were alleviated after drug reduction,symptomatic treatment and hormone treatment.Conclusion TACE+TKIs+PD-1 antibody can obtain reliable clinical efficacy and anti-tumor activity in the treatment of moderate advanced unresectable hepatocellular carcinoma.

With the advancement of comprehensive treatment and minimally invasive technology, patients with originally unresectable gallbladder cancer are expected to undergo surgical treatment after transformational therapy, which can achieve the effect of increasing R0 resection rate and improving long-term prognosis. Conversion therapy as a new option for patients with gallbladder cancer who are difficult to undergo radical surgery is still subject to much debate. Patients with locally progressive gallbladder cancer at the initial diagnosis may be the target population for conversion therapy. Gemcitabine+ cisplatin is still used as the standard first-line chemotherapy regimen. The use of multiple chemotherapeutic agents in combination also shows new vitality. High-throughput sequencing and the use of precision targeting drugs will become new trends in the future. The use of immune drugs is still needed. And the use of immunotherapy drugs is still in demand. High-throughput sequencing and the use of precision-targeted drugs will become a new trend in the future, the use of immunologic drugs still needs more evidence-based medical support, and the use of post-translational minimally invasive techniques may bring benefits to patients.

Objective:To investigate the clinical efficacy of single-incision plus one-port three dimensional (3D) laparoscopic pancreaticoduodenectomy (SILPD+1).Methods:The retrospective cohort study was conducted. The clinicopathological data of 40 patients who underwent 3D laparos-copic pancreaticoduodenectomy in Affiliated Hospital of North Sichuan Medical College from January to October 2023 were collected. There were 24 males and 16 females, aged (63±10)years. Of the 40 patients, 18 cases undergoing SILPD+1 were divided into the SILPD+1 group, and 22 cases under-going conventional five-trocar 3D laparoscopic pancreaticoduodenectomy (CLPD) were divided into the CLPD group. Observation indicators: (1) surgical situations; (2) postoperative situations and complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney rank sum test. Results:(1) Surgical situa-tions. Seventeen patients of the SILPD+1 group completed surgery successfully, and the rest of one patient with an inflammatory mass of the pancreatic head was converted to open surgery due to unclear boundary with mesenteric blood vessels and severe adhesion of surrounding tissues. All patients of the CLPD group completed surgery successfully, without conversion to open surgery. There was no significant difference in conversion to open surgery between the two groups ( P>0.05), and there was no significant difference in the volume of intraoperative blood loss, intraoperative blood transfusion or operation time ( P>0.05). (2) Postoperative situations and complications. There was no significant difference in tumor diameter, the number of lymph node dissected, the number of positive lymph node, R 0 resection, tumor type, time to postoperative first flatus, time to postopera-tive first intake liquid food, tome to first out-of-bed activity, time to postoperative drainage tube removal, duration of postoperative hospital stay, postoperative bleeding, pancreatic fistula, chylous leakage, delayed gastric emptying, abdominal fluid collection, incision infection, classification of com-plications between the two groups ( P>0.05). Postoperative pain score of the SILPD+1 group and the CLPD group was 5.0(4.5,6.0) and 6.5(6.0,7.0), respectively, showing a significant difference ( Z=-3.61, P<0.05). Both groups of patients had no occurrence of biliary fistula or abdominal infection after surgery, and there was no readmission within 30 days after surgery or no death within 90 days after surgery. Conclusions:Compared with CLPD, SILPD+1 is safe and feasible, with less postoperative pain. While ensuring oncological outcomes, SILPD+1 does not increase surgical time, postoperative hospital stay, or incidence of postoperative complications.

Objective:To analyze the impact of lymph node dissection on textbook outcomes (TO) and the prognosis of intrahepatic cholangiocarcinoma (ICC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 376 ICC patients who underwent hepatectomy in 4 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from December 2011 to December 2017 were collected. There were 242 males and 134 females, aged 57(range, 48-63)years. According to the criteria of TO, patients were classified as two cate-gories, including patients achieving TO and not achieving TO. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test, Yates adjusted chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Univariate and multivariate analyses were conducted using the Logistic regression model. The Kaplan-Meier method was used to draw survival curve. Survival analysis was conducted using the Log-rank test. Results:(1) TO situations. Of the 376 ICC patients who underwent hepatectomy, 199 cases achieved TO, including 40 cases with lymph node dissection and 159 cases without lymph node dissection, 177 cases did not achieve TO, including 76 cases with lymph node dissection and 101 cases without lymph node dissection. (2) Influencing factors for TO after hepatectomy of ICC patients. Results of multivariate analysis showed that lymph node dissection, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL were independent risk factors for achieving TO after hepatec-tomy of ICC patients ( odds ratio=2.22, 2.95, 3.58, 4.09,95% confidence interval as 1.34-3.69, 1.43-6.07, 1.40-9.17, 1.35-12.43, P<0.05). Of the 116 patients with lymph node dissection, 40 cases achieved TO, 103 cases achieved R 0 resection, 38 cases had postoperative complications, 67 cases had delayed hospital stay. The above indicators were 159, 255, 41, 65 of 260 patients without lymph node dissection. There were significant differences in the above indicators between patients with and without lymph node dissection ( χ2=22.90, 15.16, 13.95, 37.78, P<0.05). (3) Follow-up. All the 376 patients were followed up for 19(range, 1-74)months. Of 199 patients achieving TO, the 1-, 2-and 3-year survival rates of 40 patients with lymph node dissection were 54.0%, 36.6% and 26.1%, respectively, versus 67.7%, 42.7% and 34.4% of 159 patients without lymph node dissection, showing no significant difference between them ( χ2=1.89, P>0.05). Of 177 patients not achieving TO, the 1-, 2-and 3-year survival rates of 76 cases with lymph node dissection were 58.9%, 25.7% and 10.3%, respectively, versus 53.0%, 28.5% and 17.2% of 101 cases without lymph node dissection, showing no significant difference between them ( χ2=0.25, P>0.05). Conclusions:Lymph node dissec-tion, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL are independent risk factors for achieving TO after hepatectomy of ICC patients. Lymph node dissec-tion may increase the postoperative complication rate, prolong the hospital stay and decrease the rate of achieving TO. However, it does not affect the prognosis of patients.

Objective To develop the'E-Bone',a comprehensive one-stop preoperative planning system for reverse total shoulder arthroplasty with improved accuracy and efficiency.Methods The nnU-net deep neural network was utilized for scapula segmentation to obtain precise scapula segmentation results.Based on the 3 key factors,namely bone density,upward and downward angle and nail length,the base was automatically positioned.The quantitative parameters required for surgical planning were calculated.A personalized guide plate was generated by combining glenoid morphology and base positioning information.The system interface was developed to modularize various functions for easy use,providing interactive operation and real-time display.Results Compared with the Mimics system,the'E-bone'preoperative planning system reduced complex manual adjustments during the planning process.The average planned nail length was longer than that of the Mimics system,and the planning time was reduced by 86%.The scapula segmentation accuracy of this system reached 99.93%,better than that of Mimics to achieve a higher precision.Conclusion The"E-bone"system provides a one-stop,efficient,and accurate preoperative planning system for reverse shoulder replacement and potentially broader clinical applications.

Objective:To clarify the clinicopathological features, prognosis, and recurrence pattern of early-onset gastric cancer (EOGC).Methods:Using data from the gastric cancer database of Zhongshan Hospital, Fudan University, we performed a retrospective, large-scale, real-world study of 5046 patients with gastric cancer who had undergone redical or palliative gastrectomy from January 2013 to December 2018, including 425 patients with EOGC (age ≤45 years) and 4621 controls. All those patients were pathologically confirmed adenocarcinoma with complete follow-up of five years. Residue gastric cancer and patients without complete clinical or follow-up data were excluded. We used a combination of outpatient and telephone follow-up, ending in October 2022 (median duration of follow-up 60 months), and compared the clinicopathological features and prognosis of the two groups.Results:The clinicopathological features of EOGC included female predominance (61.1% [262/425 vs. 26.3% [1217/4621], χ 2=234.215, P<0.001), fewer comorbidities (31.3% [133/425] vs. 58.5% [2703/4621], χ 2=34.378, P<0.001), poorer differentiation (90.6% [385/425] vs. 78.2% [3614/4621], χ 2=30.642, P<0.001), higher proportion of diffuse type (53.9% [229/425] vs. 18.3% [846/4621], χ 2=274.474, P<0.001), higher proportion of T4 stage (44.7% [190/425] vs. 37.5% [1733/4621], χ 2=17.535, P=0.001), more lymph node metastases (60.5% [257/425] vs. 53.9% [2491/4621], χ 2=6.764, P=0.009), and higher proportion of pathological stage III/IV (47.5% [202/425] vs. 42.4% [1959/4621], χ 2=4.093, P=0.043). The 5-year overall survival rates of the EOGC and control groups were 55.1% and 49.1%, respectively. Overall survival was significantly better in the EOGC than in the control group ( P<0.001). According to subgroup analysis, the prognosis of pathological stage I/II/III EOGC was better than that of the control group. Recurrence rates were similar in the two groups, whereas patients with EOGC had a higher proportion of peritoneal recurrence (7.8% [33/425] vs. 3.2% [146/4621], χ 2=23.741, P<0.001) and a lower proportion of distant metastasis (4.9% [21/425] vs. 8.3% [385/4621], χ 2=6.247, P=0.012). Conclusion:EOGC has unique clinicopathological features and recurrence patterns and resectable EOGC has a better prognosis, suggesting that patients with EOGC should be actively treated with the focus on preventing peritoneal recurrence.
