Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

OBJECTIVE To investigate and analyze the operational costs and current charging policies of pharmacy intravenous admixture service （PIVAS） in China， and provide a reference for promoting high-quality and sustainable development of PIVAS. METHODS Questionnaires were distributed in 30 provinces， autonomous regions， and municipalities across the country through the “Wenjuanxing” platform from May 6th to July 1st， 2022. The operational costs， charging status and suggestions of PIVAS were investigated and analyzed. RESULTS A total of 761 PIVAS participated in the survey nationwide， including 666 tertiary medical institutions， 93 secondary medical institutions， and 2 primary medical institutions. Approximately 60.58% of PIVAS had implemented a charging system that allowed charges. Among them， most PIVAS required inspection and evaluation before charging. The annual operating cost of PIVAS in China was approximately 2 098 100 yuan， with the integrated operating cost comprising 89.36% of the total， while the dispensing cost accounted for only 10.64%. Human costs emerged as the highest annual consumption （74.20%）， followed by decoration and facility maintenance costs （4.77%） and equipment acquisition costs （3.44%）. Regarding charges for different drugs nationwide， common drugs had an average charge standard of 4.39 yuan per bag while antibacterial drugs averaged 5.01 yuan per bag； hazardous drugs had an average charge of 23.17 yuan per bag， whereas parenteral nutrition solutions averaged 38.75 yuan per bag. However， the recommended average charges of the four drugs mentioned above were 6.71， 9.63， 38.35 and 44.03 yuan per bag， respectively. CONCLUSIONS At present， there is no unified inspection and evaluation standard and charging standard in China. Moreover， the current charging standard is lower than the recommended standard. It is necessary to combine operational costs and develop more reasonable and fair charging standards.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE To observe the curative effect of bacterial lysates(BLs)combined with intranasal corticosteroids(INCS)in the treatment of chronic rhinosinusitis(CRS).METHODS Cases diagnosed as CRS with nasal polyps(CRSwNP)and CRS without nasal polyps(CRSsNP)were collected and divided into four groups:CRSwNP with BLs group,CRSwNP control group,CRSsNP with BLS group and CRSsNP control group.All patients received surgical treatment,the control group received postoperative INCS therapy,and the BLs group received postoperative INCS+BLs oral therapy.Visual analogue scale(VAS),sino-nasal outcome test-20(SNOT-20),Lund-Kennedy score,Lund-Mackay score,eosinophilic(Eos)cell,IL-4,IgG,IgA,IgM and total IgE levels were evaluated before,1 month and 3 months after surgery.RESULTS Significant differences in IgG,IgA,IL-4 and Eos levels between CRSwNP and CRSsNP with BLs groups(P<0.05).There were significant differences in VAS and SNOT-20 between CRSwNP group and CRSsNP with BLs group at 1 and 3 months after treatment(P<0.05).At 1 month and 3 months after treatment,there were statistically significant differences in Lund-Kennedy score and Lund-Mackey score between the CRSwNP group and the CRSsNP with BLs group(P<0.05).The effective rate of disease control in the four groups after treatment was statistically significant(P<0.05).There were no serious complications directly related to the treatment.CONCLUSION The application of BLs can improve postoperative rhinorrhea,persistent inflammatory and mucosal recovery in patients with CRS,increase IgG and IgA levels,reduce Eos and IL-4 levels,reduce adverse reactions,and improve the therapeutic effect of CRS with high safety.

ObjectiveTo investigate the targets and mechanism of Baofeikang granules in the treatment of pulmonary fibrosis based on network pharmacology and verify the predicted mechanism based on animal experiment. MethodThe active ingredients and targets of Baofeikang granules were screened via the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform， and the targets of pulmonary fibrosis were searched in various disease databases. The common targets shared by Baofeikang granules and the disease were extracted for the establishment of the protein-protein interaction （PPI） network in STRING. Cytoscape 3.8.0 was used to analyze the network topology of the key targets and to establish the ''active ingredient-target'' network. Gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses were performed on the core targets to explore their possible molecular mechanisms. The rats were assigned into four groups： normal group， model group， prednisone acetate group， and Baofeikang granules group. The rat model of interstitial lung fibrosis was established by tracheal instillation of bleomycin. After 21 days of gavage， the lung tissues of rats were stained with hemotoxylin and eosin （HE） for the observation of morphological changes， and phosphatidylinositol 3-kinase （PI3K） and protein kinase B （Akt） were detected via immunohistochemical （IHC） staining. ResultBased on network pharmacology， 18 key targets of Baofeikang granules were identified for the treatment of pulmonary interstitial fibrosis， including Akt1， mitogen-activated protein kinase （MAPK） 1， myelocytomatosis oncogene （MYC）， hypoxia-inducible factor-1α （HIF-1α）， cyclin-dependent kinase inhibitor 1A （CDKN1A）， epidermal growth factor receptor （EGFR）， and Runt-related transcription factor （RUNX2）. KEGG pathway enrichment predicted that Baofeikang granules exerted anti-fibrotic effect mainly through PI3K/Akt， tumor necrosis factor （TNF）， and interleukin-17 （IL-17） signaling pathways. The IHC results in animal experiment showed that the protein levels of PI3K and Akt were lower in the Baofeikang granules group than in the model group （P<0.05， P<0.01）. ConclusionBaofeikang granules has low toxicity， multiple targets， and multiple pathways in the treatment of pulmonary fibrosis. It may alleviate pulmonary fibrosis through regulating PI3K/Akt signaling pathway， so as to improve the lung function.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To investigate the survival and prognosis of B-lineage acute lymphoblastic leukemia (B-ALL) patients with TP53 mutation.Methods:The clinical data of 479 newly diagnosed B-ALL patients treated in the First Affiliated Hospital of Soochow University from January 2016 to December 2019 were retrospectively analyzed.Results:Among 479 B-ALL patients, 34 cases (7.1%) were positive for TP53 gene mutation, and a total of 36 TP53 mutations were detected, including 10 frameshift gene mutations (27.8%) , 23 missense mutations (63.9%) and 3 nonsense mutations (8.3%) . A total of 34 (94.4%) mutations were located in the DNA binding domain (exons 5-8) .The average number of mutated genes in patients with TP53 gene mutation (2.3) and the group without TP53 gene mutation (1.1) were statistically different ( P<0.001) . The proportion of Ph positive and Ph-like positive patients in the TP53 gene mutation negative group was significantly higher than that of the TP53 mutation positive group, and the difference was statistically significant ( P<0.001) . The 3-year OS and EFS rates of the TP53 gene mutation negative group were significantly higher than those of the TP53 gene mutation positive group. The differences in OS and EFS rates between the two groups were statistically significant ( χ2= 4.694, P = 0.030; χ2= 5.080, P= 0.024) . In the multivariate analysis, failure to achieve remission (CR) after one course of induction chemotherapy was an independent adverse prognostic factor affecting OS.Of the 34 patients with TP53 mutation, 16 underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the CR 1 state, and 2 patients with recurrence after transplantation obtained CR 2 after infusion of donor-derived anti-CD19 chimeric antigen receptor T (CAR-T) cells. Among the 11 patients with TP53 gene mutation who relapsed during consolidation chemotherapy, 6 received anti-CD19 CAR T cell therapy, 4 patients achieved remission and minimal residual disease (MRD) turned negative, followed by bridging allo-HSCT, and 2 of them sustained CR. Conclusion:Missense mutations are the most common in B-ALL patients with TP53 gene mutation, and the majority of mutations were located in the DNA binding domain. B-ALL patients with TP53 gene mutation should undergo allo-HSCT as soon as possible after CAR-T cell therapy has cleared the MRD after recurrence. B-ALL patients with TP53 gene mutation still have a higher recurrence rate after allo-HSCT, and the infusion of donor-derived CAR-T cells can achieve better sustained remission.

Peptide receptor radionuclide therapy (PRRT),being investigated as an effective treatment for inoperable gastroenteropancreatic neuroendocrine tumor,has gained much importance in recent years.With increasing data of clinical trials and the exploration of different radionuclides as well as the toxic and side effects,PRRT has developed continuously and play a marked role on the treatment of gastroenteropancreatic neuroendocrine tumor.

OBJECTIVETo investigate clinicopathological features and prognostic factors of appendiceal neuroendocrine neoplasms(a-NEN).

METHODSClinical data of 20 patients diagnosed with a-NEN at Zhongshan Hospital of Fudan University between January 2000 and December 2016 were retrospectively analyzed. Pathological diagnosis was based on the WHO classification criteria of digestive system tumors (2010 edition). Based on the mitotic count and Ki-67 index, a-NENs were divided into grade 1 neuroendocrine tumor (NET G1), grade 2(G2) NET G2) and grade 3 (neuroendocrine carcinoma, NEC). Some special types of a-NEN (e.g. goblet cell carcinoid) and mixed adenoneuroendocrine neoplasms were classified as mixed adenoneuroendocrine carcinoma (MANEC). Follow-up was conducted by telephone or return visits. Univariate analysis was carried out using the Kaplan-Meier method, and the log-rank test was used to draw survival curves.

RESULTSOf 20 patients, 14 were male and 6 were female with median age of 54 years. Seventeen cases presented acute right lower quadrant abdominal pain, 1 chronic right lower quadrant abdominal pain, 1 persistent abdominal discomfort with outburst whole abdominal pain and 1 was found during body check without symptoms. Twenty cases comprised 8 G1 patients, 4 G2 patients, 3 G3 patients, and 5 MANEC patients. When diagnosed, there was 1 patient with liver metastasis, 1 patient with abdominal and pelvic metastases, and 2 patients with postoperative pathological findings of lymph node metastasis. Six patients underwent appendectomy, 12 underwent right hemicolectomy, 1 underwent right hemicolectomy plus small intestine resection, and 1 underwent partial hepatectomy plus right hemicolectomy. The follow-up time was 7-187 months(average, 36 months). The total 1- and 3-year survival rates were 94.7% and 60.2%, respectively. Univariate analysis showed that age >50 years (χ=7.036, P=0.008), pathology grade as MANEC (χ=5.297, P=0.021), and metastasis (χ=6.558, P=0.010) indicated lower 5-year survival rate.

CONCLUSIONSMost a-NEN patients have no typical symptoms, and the main complaint at consultation is acute right lower quadrant abdominal pain. Prognosis is poor for patients with age >50 years, MANEC pathology grade and metastasis.
