Xiao Chaihutang， originating from the Treatise on Typhoid and Miscellaneous Diseases， is a classic formula for harmonizing the Shaoyang. It excels in regulating the pivotal mechanism and unblocking the triple energizer， corresponding to the pathogenesis of digestive system tumors characterized by the interlocking of deficiency， stasis， phlegm， and toxicity， as well as disharmony between Yin and Yang. This paper systematically reviews research findings from China and abroad over the past decade， exploring the anti-tumor effects of Xiao Chaihutang on digestive system tumors from three dimensions： theoretical rationale， clinical efficacy， and molecular mechanisms. At the level of principle and method， Xiao Chaihutang takes "harmonization" as its core therapeutic guideline. By reconciling the exterior and interior to restore the Shaoyang pivot， harmonizing Yin and Yang to improve the tumor microenvironment， and regulating the liver and spleen to consolidate and protect the foundation of postnatal essence， it promotes the restoration of the body's dynamic balance of Yin and Yang. Clinical studies have demonstrated that Xiao Chaihutang， used alone or in combination with modern medical therapies， shows definite efficacy against digestive system tumors such as hepatocellular carcinoma， pancreatic carcinoma， and gastrointestinal carcinoma. It can significantly improve patients' quality of life， inhibit tumor progression， effectively relieve concomitant symptoms such a s cancer-related fever， anxiety， depression， and insomnia， and alleviate postoperative embolic syndromes as well as adverse reactions to radiotherapy and chemotherapy. Experimental studies have revealed that Xiao Chaihutang can inhibit tumor cell proliferation， induce apoptosis， arrest the cell cycle， suppress tumor cell invasion and metastasis， and improve the tumor microenvironment. Through the above analysis， this study elucidates the current clinical and experimental research status of Xiao Chaihutang in the treatment of digestive system tumors， aiming to provide theoretical support for its precise clinical application. On this basis， it further explores key issues in the identification of pharmacodynamic substances and the accumulation of evidence in evidence-based medicine， thereby offering a new perspective for the innovative development of integrative Chinese and Western medicine in synergistic cancer therapy.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To investigate the expression of trophoblast cell-surface antigen 2(TROP2)in salivary ade-noid cystic carcinoma(SACC)in order to analyze its relationship with TROP2 expression and clinicopathological features,as well as to clarify the correlation between TROP2 expression and the prognosis of patients with SACC.Methods With approval from the ethics committee,the expression of TROP2 in 85 SACC and paracancer tissue sam-ples was detected by using the immunohistochemical method,and the relationship between TROP2 expression and clini-copathological characteristics was analyzed.The Kaplan-Meier method was used to analyze the relationship between TROP2 protein expression and 5-year disease-free survival(DFS)in 40 patients with SACC.Furthermore,the logistic re-gression model was used to analyze the prognostic factors of patients with SACC.Results The low or no expression rate of TROP2 in SACC tissues was significantly higher than that in paracancer tissues(P＜0.001).Low or no expres-sion of TROP2 was significantly positively correlated with tumor growth and clinical staging in patients with SACC(P＜0.05).Kaplan-Meier survival analysis showed that the DFS of patients with SACC with low or no expression of TROP2 protein was significantly lower than those of patients with high expression of TROP2 protein(P＜0.05),and the progno-sis was poor.The logistic regression model showed that low or no expression of TROP2 protein(OR=5.37;95%CI:1.03-28.08;P=0.046)and Ⅲ-Ⅳ clinical staging(OR=6.89;95%CI:1.37～34.77;P=0.019)were risk factors affect-ing the prognosis of patients with SACC.Conclusion Low or no expression of TROP2 protein in SACC tissues leads to poor prognosis of patients and is positively correlated with tumor growth and clinical staging.In addition,low or no ex-pression of TROP2 can be used as an independent prognostic risk factor for poor prognosis in patients with SACC,and TROP2 is a marker of poor prognosis in patients with SACC.

Background and purpose:Human epidermal growth factor receptor 2(HER2)is closely associated with drug efficacy and prognosis in urothelial carcinoma(UC).HER2 is a significant biomarker and therapeutic target in various tumors.In recent years,anti-HER2 antibody-drug conjugates have shown significant clinical efficacy in UC patients with HER2 overexpression.Therefore,an in-depth understanding of HER2 expression and its characteristics in Chinese UC patients is crucial to guide treatment decision-making,optimize treatment strategies and achieve personalized therapy.This study aimed to thoroughly investigate correlation of HER2 expression and clinicopathological characteristics in Chinese patients with UC.Methods:This study was a multicenter study that retrospectively included UC patients from urology departments of 8 tertiary hospitals in 5 geographical regions of China(North China,East China,South China,Central China and Northwest)whose tissue samples were collected from January 2023 to March 2024.Inclusion criteria:① age above 18 years;② UC diagnosed by histopathological or cytological examination;③ complete results of HER2 expression detection using immunohistochemistry(IHC)in the primary tumor site were required.Exclusion criteria:① diagnosed patients with tumors in other parts of the body;② physicians evaluated other situations that were not suitable for inclusion in this study.IHC results for HER2 expression and clinicopathological data were collected.HER2 expression was determined according to the criteria outlined in"Clinical pathological expert consensus on HER2 testing in urothelial carcinoma in China",with HER2 2+and 3+defined as HER2 overexpression.The HER2 expression and clinicopathological features were analyzed.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethical number:2301268-12)and was registered at China Clinical Trial Registry(registration number:ChiCTR2300069746).Results:A total of 1054 patients with UC were included.Most of the tumors were bladder UC(n=807,76.6%).The mean age of patients was(66.8±10.5)years,and the majority were male(78.5%).The HER2 overexpression rate was 58.4%(n=616),with an additional 23%of patients having HER2 1+expression(n=242),and a small proportion exhibiting negative HER2 expression(n=196,18.6%).HER2 expression was significantly associated with various clinical and pathological characteristics such as Eastern Cooperative Oncology Group(ECOG)performance status,history of cardiovascular disease,history of metabolic disorders,smoking,UC disease location,differentiation grade,pathological type,and tumor stage.Conclusion:Retrospective analysis of multi-center data shows that HER2 expression is frequently observed in Chinese UC patients,with an overexpression rate of up to 58.4%.Furthermore,HER2 expression is closely associated with various clinical and pathological features of UC patients.This study underscores the critical importance of accurately assessing HER2 expression in UC patient to guide personalized therapies.

Alfalfa(Medicago sativa L.)is the most important legume forage crop worldwide with high nutritional value and yield.For a long time,the breeding of alfalfa was hampered by lacking reliable information on the autotetraploid genome and molecular markers linked to important agro-nomic traits.We herein reported the de novo assembly of the allele-aware chromosome-level genome of Zhongmu-4,a cultivar widely cultivated in China,and a comprehensive database of genomic variations based on resequencing of 220 germplasms.Approximate 2.74 Gb contigs(N50 of 2.06 Mb),accounting for 88.39％of the estimated genome,were assembled,and 2.56 Gb contigs were anchored to 32 pseudo-chromosomes.A total of 34,922 allelic genes were identified from the allele-aware genome.We observed the expansion of gene families,especially those related to the nitrogen metabolism,and the increase of repetitive elements including transposable elements,which probably resulted in the increase of Zhongmu-4 genome compared with Medicago truncatula.Population structure analysis revealed that the accessions from Asia and South America had rela-tively lower genetic diversity than those from Europe,suggesting that geography may influence alfalfa genetic divergence during local adaption.Genome-wide association studies identified 101 sin-gle nucleotide polymorphisms(SNPs)associated with 27 agronomic traits.Two candidate genes were predicted to be correlated with fall dormancy and salt response.We believe that the allele-aware chromosome-level genome sequence of Zhongmu-4 combined with the resequencing data of the diverse alfalfa germplasms will facilitate genetic research and genomics-assisted breeding in variety improvement of alfalfa.

Objective:To observe the effects of intervention based on self-regulation mode on illness perception, medical coping styles and quality of life of patients with psoriasis.Methods:Eighty patients with psoriasis from February 2018 to August 2019 in Qinhuangdao First Hospital were selected and divided into two groups by random digits table method, 40 patients in each group. The control group was given routine intervention, and the experimental group was given intervention based on self-regulation mode. The Illness Perception Questionnaire-Revised (IPQ-R) scores, Medical Coping Modes Questionnaire (MCMQ) scores, dermatologylifequalityindex (DLQI) scores and compliance of the two groups were compared before and after intervention.Results:There was no significant difference in the score of IPQ-R, MCMQ, DLQI before intervention between the two groups( P>0.05). After intervention, scores of symptoms, disease perception and causes of the disease in IPQ-R were (7.24±0.75), (162.34±20.35), (76.23±8.65) points in the experimental group and (6.08±0.72), (123.26±18.57), (52.79±7.84) points in the control group, there were significant differences between the two groups ( t values were 7.057, 8.972, 12.699, P<0.01). In the MCMQ, facing score,avoidance score and yielding score were (25.67±2.83), (12.26±1.84), (9.12±1.24) points in the experimental group, (21.76±3.89), (14.35±2.48), (10.45±1.68) points in the control group, there were significant differences between the two groups ( t values were 5.141, -4.280, -4.028, P<0.01). The DLQI scores of experimental group were significantly higher than those of control group ( t values were 2.648-8.244, P<0.05 or 0.01), and compliance of experimental group (97.5%, 39/40) was significantly better than control group (80.00%, 32/40) with statistically significant( Z value was 40.000, P<0.01). Conclusions:Intervention based on self-regulation mode can effectively reduce negative emotions of patients with psoriasis, increase their illness perception and compliance, improve their medical coping styles, self-management ability and quality of life, with positive application value.

Objective To evaluate the clinical value of holographic image navigation in urological laparoscopic and robotic surgery.Methods The data of patients were reviewed retrospectively for whom accepted holographic image navigation laparoscopic and robotic surgery from Jan.2019 to Dec.2019 in Beijing United Family Hospital and other 18 medical centers,including 78 cases of renal tumor,2 cases of bladder cancer,2 cases of adrenal gland tumor,1 cases of renal cyst,1 case of prostate cancer,1 case of sweat gland carcinoma with lymph node metastasis,1 case of pelvic metastasis after radical cystectomy.All the patients underwent operations.In the laparoscopic surgery group,there were 27 cases of partial nephrectomy,1 case of radical prostatectomy,2 cases of radical cystectomy and 2 cases of adrenalectomy.In the da Vinci robotic surgery group of 54 cases,there were 51 cases of partial nephrectomy,1 case of retroperitoneal lymph node dissection,1 case of retroperitoneal bilateral renal cyst deroofing and 1 case of resection of pelvic metastasis.There were 41 partial nephrectomy patients with available clinical data for statistic,with a median age of 53.5 years (range 24-76),including 26 males and 15 females.The median R.E.N.A.L score was 7.8 (range 4-11).Before the operation,the engineers established the holographic image based on the contrast CT images and reports.The surgeon applied the holographic image for preoperative planning.During the operation,the navigation was achieved by real time fusing holographic images with the laparoscopic surgery images in the screen.Results All the procedures had been complete uneventfully.The holographic images helped surgeon in understanding the visual three-dimension structure and relation of vessels supplying tumor or resection tissue,lymph nodes and nerves.By manipulating the holographic images extracorporeally,the fused image guide surgeons about location vessel,lymph node and other important structure and then facilitate the delicate dissection.For the 41 cases with available clinical data including 23 cases of robotic-assisted partial nephrectomy and 18 cases of laparoscopic nephrectomy,the median operation time was 140 (range 50-225) min,the median warm ischemia time was 23 (range 14-60) min,the median blood loss was 80(range 5-1 200) ml.In the robotic surgery group,the median operation time was 140 (range 50-215)min,the median warm i schemia time was 21 (range 17-40)min,the median blood loss was 150(range 30-1 200)ml.In the laparoscopic surgery group,the median operation time was 160(range 80-225)min,the median warm ischemia time was 25 (range 14-60)min,the median blood loss was 50 (range 5-1 200) ml.All the patients had no adjacent organ injury during operation.There were 2 cases with Clavien Ⅱ complications.One required transfusion and the other one suffered hematoma post-operation.However,the tumors were located in the renal hilus for these 2 cases and the R.E.N.A.L scores were both 11.Conclusions Holographic image navigation can help location and recognize important anatomic structures during the surgical procedures..This technique will reduce the tissue injury,decrease the complications and improve the success rate of surgery.

Objective:To evaluate the modified efficacy of thoracic paravertebral block (TPVB) combined with general anesthesia in the patients undergoing laparoscopic radical nephrectomy.Methods:Eighty patients, aged 38-64 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective laparoscopic radical nephrectomy, were selected and randomly divided into 2 groups ( n=40 each) using a random number table method: general anesthesia group (group GA) and TPVB combined with general anesthesia group (group TPVB+ GA). A paravertebral catheter was placed at T 8 and T 10 under ultrasound guidance before induction of anesthesia, and 0.5% ropivacaine 10 ml was administered via the catheter in group TPVB+ GA.Anesthesia was induced with propofol, sufentanil, etomidate and rocuronium and maintained by intravenous infusion of propofol and remifentanil.Patient-controlled intravenous analgesia was performed with sufentanil, ketorolac tromethamine and tropisetron at the end of surgery.When postoperative visual analog scale score≥4, tramadol 50 mg was intravenously injected as rescue analgesic.Immediately before anesthesia induction (T 0), at 5 min after establishing pneumoperitoneum (T 1), at 2 h of pneumoperitoneum (T 2), and immediately after the end of pneumoperitoneum (T 3), and at 24 h after operation (T 4), venous blood samples were collected for determination of plasma norepinephrine concentrations (by enzyme-linked immunosorbent assay), plasma cortisol level (using radioimmunoassay), and blood glucose concentrations were measured.The intraoperative consumption of sufentanil and remifentanil was recorded.The intraoperative hypertension, hypotension, and bradycardia were recorded, and the nausea and vomiting, pruritus, and requirement for rescue analgesia occurred within 24 h after surgery were recorded. Results:Compared with group GA, the plasma concentrations of norepinephrine, cortisol and blood glucose were significantly decreased at T 1-4, the intraoperative consumption of sufentanil and remifentanil was reduced, and the postoperative requirement for rescue analgesia was decreased in group TPVB+ GA ( P<0.05). There was no significant difference in the incidence of intraoperative and postoperative adverse reactions between the two groups ( P>0.05). Conclusion:TPVB combined with general anesthesia is helpful in carrying out the anesthetic model of low-consumption opioids and is more helpful in inhibiting intraoperative and postoperative stress responses and postoperative pain responses than general anesthesia alone when used for laparoscopic radical nephrectomy.
