By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

Objective To systematically review the risk prediction models for postoperative pancreatic fistula(POPF)after pancreaticoduodenectomy(PD),and to provide a reference for the clinical screening and application of POPF-related risk models.Methods This study was conducted according to the PRISMA guidelines,with a PROSPERO registration number of CRD42023437672.PubMed,Scopus,Embase,Web of Science,the Cochrane Library,CNKI,VIP,Wanfang Data,China Medical Journal Full-text Database,and CBM were searched for studies on establishing risk prediction models for POPF after PD published up to April 26,2024.The PROBAST tool was used to assess the quality of articles,and RevMan 5.4 and MedCalc were used to perform the Meta-analysis.Results A total of 36 studies were included,involving 20 119 in total,and the incidence rate of POPF after PD was 7.4%—47.8%.A total of 55 risk prediction models were established in the 36 articles,with an area under the receiver operating characteristic curve(AUC)of 0.690-0.952,among which 52 models had an AUC of>0.7.The quality assessment of the articles showed high risk of bias and good applicability.MedCalc was used to perform a statistical analysis of AUC values,and the results showed a pooled AUC of 0.833(95%confidence interval:0.808-0.857).The Meta-analysis showed that body mass index,amylase in drainage fluid on the first day after surgery,preoperative serum albumin,pancreatic duct diameter,pancreatic texture,fat score,tumor location,blood loss,sex,time of operation,main pancreatic duct index,and pancreatic CT value were predictive factors for POPF(all P<0.05).Conclusion The risk prediction models for POPF after PD is still in the exploratory stage.There is a lack of calibration methods and internal validation for most prediction models,and only the univariate analysis is used to for the screening of variables,which leads to the high risk of bias.In the future,it is necessary to improve the methods for model establishment,so as to develop risk prediction models with a higher prediction accuracy.

Objective:To analyze the clinical outcomes of initial radioactive iodine 131I therapy (RIT) for patients with familial differentiated thyroid cancer (FDTC) and sporadic differentiated thyroid cancer (SDTC), along with their influencing factors. Methods:The clinical data of 120 FDTC and 480 SDTC patients who received RIT at the Department of Nuclear Medicine, Tianjin Medical University General Hospital from January 2016 to January 2022 were retrospectively analyzed. These patients, categorized into the FDTC and SDTC groups, were further divided into three subgroups based on their response to initial RIT: no evidence of disease (NED), biochemical persistence of disease (BPD), or structural/functional persistence of disease (S/FPD). For the NED subgroup, the disease-free survival (DFS) was analyzed. For the BPD and S/FPD subgroups, the progression-free survival (PFS) was investigated. Furthermore, risk factors for failure to reach the NED status were identified.Results:After initial RIT, 56 (46.7%), 50 (41.7%), 14 (11.6%) patients in the FDTC group reached the NED, BPD, and S/FPD statuses, respectively, while 284 (59.1%), 160 (33.3%), 36 (7.5%) and SDTC patients in the SDTC group were in the NED, BPD, and S/FPD statuses, respectively ( χ2 = 10.10, P = 0.013). The last follow-up revealed that 71 (59.1%), 36 (30.1%), 13 (10.8%) patients in the FDTC group were in the NED, BPD and S/FPD statuses, respectively, while 337 (70.2%), 114 (23.7%), 29 (6.1%) patients in the SDTC group reached the NED, BPD and S/FPD statuses, respectively ( χ2 = 8.99, P = 0.026). The F-NED and S-NED subgroups exhibited 5-year DFS rates of 92.4% and 97.4%, respectively, the F-BPD and S-BPD subgroups displayed 5-year PFS rates of 88.3% and 90.8%, respectively, while the F-S/FPD and S-S/FPD subgroups yielded in 5-year PFS rates of 78.2% and 79.6%, respectively. Univariate binary logistic regression analysis indicated that the maximum diameter of tumors, T stage, M stage, recurrence risk stratification, and postoperative stimulated thyroglobulin (p-sTg) were correlated with the achievement of the NED status ( χ2=6.37-13.10, P < 0.05). Multivariable binary logistic regression analysis showed that T stage and p-sTg were independent risk factors in the achievement of the NED status ( χ2=0.11-11.33, P < 0.05). Conclusions:The response to initial RIT assists in guiding the development of subsequent treatment and follow-up strategies for DTC patients. Given that the SDTC patients exhibited better outcomes than the FDTC patients, more alertness should be paid to the RIT for FDTC patients. For patients with higher p-sTg and T stage, the initial RIT dose and follow-up interval should be increased and reduced respectively as appropriate.

Aim To investigate the role of mitochondrial translocator protein(TSPO)in the apoptosis of HepG2 cells induced by tanshinone IIA(Tan II A)and the involved mechanism. Methods Following the HepG2 cells treated with Tan ⅡA at 2.5, 5 and 10 μmol·L-1, the cell viability was determined by MTT assay, and intracellular ATP content was determined by luciferin-luciferase method. Oxygen utilization was measured polarographically with a Clark oxygen electrode. Cell apoptosis was determined by Hoechst 33342 staining and flow cytometry. The mitochondrial membrane potential was assessed with JC-1 staining. The intracellular distribution of TSPO was examined by TSPO immunostaining, and the expressions of TSPO, Cyto C, caspase-3, caspase-9 were determined by immunoblotting analysis. Results Tan II A inhibited the proliferation of HepG2 cells in a dose-and time-dependent manner. The treatment with Tan II A inhibited ATP production and oxygen utilization of mitochondria. In addition, Tan ⅡA enhanced TSPO expression and accumulation in nuclei and up-regulated the expression of Cyto C, caspase-3 and caspase-9. Conclusions Tan II A induces the apoptosis of HepG2 cells, which may be related to the TSPO-mediated mitochondrial dysfunction.

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Objective:To analyze the metabolic mechanism of papillary thyroid cancer(PTC) in normal and Hashimoto′s thyroiditis(HT) background, and to explore the relationship between HT and PTC.Methods:This study included a matched sample set collected from Tianjin Medical University General Hospital between January 2018 and January 2019, consisting of PTC and paracancular tissue from 31 cases with coexisting HT(HT group), and 30 cases without(NC group), all confirmed pathologically following thyroidectomy. The ultra-high performance liquid chromatography combined with mixed four-stage poles time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to acquire data from the samples. Metabolite differences between the two groups were compared, aiming to identify distinct metabolic mechanisms of PTC under different backgrounds. Metabolic pathway analysis was conducted using Metabo-Analyst 5.0 to explore relevant metabolic pathways.Results:The HT group and NC group shared 7 common differentially expressed metabolites, including arginine, glutamic acid, cysteine, citric acid, malic acid, uracil, and taurine. Logistic regression model combined with receiver operating characteristic(ROC) analysis of these 7 biomarkers yielded excellent discriminatory capacity for PTC(area under ROC curve of HT group and NC group were 0.867 and 0.973, respectively). The common metabolic pathways were taurine and hypotaurine metabolism, arginine biosynthesis, alanine, aspartic acid and glutamic acid metabolism, arginine and proline metabolism, and glutamine and glutamic acid metabolism. The specific metabolic pathways in HT group were aminoacyl tRNA biosynthesis, glycine, serine, and threonine metabolism.Conclusion:The metabolic profiles of thyroid cancer exhibit significant differences between cases with normal backgrounds and those with HT. The specific pathways for PTC and HT are aminoacyl tRNA biosynthesis and the metabolism of glycine, serine, and threonine.

In order to provide the basis for the development of famous classical formulas， the name， origin， quality evaluation， harvesting and processing of Eucommiae Cortex were systematically researched by consulting the ancient herbal and medical books， combining with the modern literature. According to the textual research， materia medica in the past dynasties used Eucommiae Cortex as the correct name. Combined with characteristics， origin and efficacy， Eucommiae Cortex in ancient times to the present is the dry bark of Eucommia ulmoides from family Eucommiaceae. The earliest producing areas of Eucommiae Cortex are Henan， Shanxi， Shaanxi and Sichuan. Since the Ming dynasty， the producing areas have expanded to most of the regions in the country， and Sichuan， Shaanxi， Chongqing， Guizhou and Hubei are regarded as the authentic producing areas. It has been concluded that the quality of Eucommiae Cortex is best if the bark has thick body， large block， scraped rough skin， multi silk section and dark purple internal surface. In ancient times， the processing methods of Eucommiae Cortex were mainly included removing rough bark and cutting for raw use， processing with auxiliary materials such as honey， ginger juice， salt water， wine， and so on. While in modern times， the processing methods have become increasingly simplified which are mainly cutting raw materials after cleansing and salt processing. It is need to excavate the connotation of different processed products and restore the traditional main processing methods through standards. Based on the requirement of Eucommiae Cortex in Sanbitang， it is suggested to use ginger-processed products according to the research results， which is used ginger juice as auxiliary material and processed with stir frying method according to the 2020 edition of Chinese Pharmacopoeia.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

ObjectiveTo explore the mechanism of Xianglian Huazhuo prescription in the treatment of chronic atrophic gastritis （CAG） based on network pharmacology and animal experiments，so as to provide scientific basis for clinical application. MethodThe possible targets and pathways of Xianglian Huazhuo prescription in the treatment of CAG were obtained based on the prediction of network pharmacology. The CAG rat model was induced by sodium salicylate，N-methyl-N'-nitro-N-nitrosoguanidine （MNNG） and hunger and satiety disorder. Then the CAG rats were treated with Xianglian Huazhuo prescription and morodan for 60 days. After administration，the rats were sacrificed，and the content of interleukin-6 （IL-6），tumor necrosis factor-α （TNF-α），interleukin-1β （IL-1β） and vascular endothelial growth factor （VEGF） in serum was determined by enzyme linked immunosorbent assay（ELISA）. In addition， the protein expression of Bad and Bcl-2 in gastric mucosa was detected by immunohistochemistry （IHC）. ResultA total of 241 active components of Xianglian Huazhuo prescription and 53 core targets were obtained. Xianglian Huazhuo prescription affected multiple biological processes，such as cell proliferation and apoptosis，inflammatory reaction，regulation of DNA metabolism，and cell response to redox，as well as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt），TNF，mitogen-activated protein kinase （MAPK），cancer and cancer-related signaling pathways. The animal model verification showed that Xianglian Huazhuo prescription lowered the levels of IL-6，TNF-α，IL-1β and VEGF in serum of CAG rats，and reduced the protein expression of Bad and Bcl-2 in gastric tissue. ConclusionXianglian Huazhuo prescription could regulate PI3K/Akt signal pathway and improve gastric mucosal injury in CAG by participating in biological processes such as cell proliferation，apoptosis and inflammation.

Objective:To analyze the short-term effect of targeted drugs on quality of life in patients with radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC).Methods:From February 2020 to April 2022, 19 RAIR-DTC patients (10 males, 9 females; age (54.5±14.5) years) who received targeted drugs therapy (sorafenib, lenvatinib or anlotinib) in Tianjin Medical University General Hospital were prospectively enrolled. The thyroglobulin (Tg) levels prior and 1, 3, 6 months post the targeted treatment, and the adverse events were measured and recorded. Response evaluation criteria in solid tumors (RECIST) 1.1 version was used to evaluate the treatment response. The quality of life based on five-level EuroQol five-dimensional questionnaire (EQ-5D-5L) was monitored prior and 3 months post the targeted treatment, and the prevalence rates of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression were analyzed, and the scores of health assessment were assessed. Paired t test, Kruskal-Wallis rank sum test and χ2 test were used to analyze data. Results:The prevalence rates of mobility (8/19), self-care (6/19), usual activities (10/19), pain/discomfort (10/19), and anxiety/depression (12/19) in 3 months post treatment were higher than those prior treatment (1/19, 1/19, 1/19, 2/19, 2/19; χ2 values: 4.38-11.31, all P<0.05). The score of health assessment prior treatment was (84.37±6.25), which was higher than that at 3 months post treatment (71.63±9.14; t=5.02, P=0.001). After targeted treatment, 10 patients were with skin toxicity, 8 patients were with hypertension, 8 patients were with weight loss, 7 patients were with diarrhea, 6 patients were with fatigue, 5 patients were with hepatic dysfunction, 2 patients were with proteinuria, 2 patients were with muscle pain and 1 patient was with oral ulcer. Of 19 patients, 17 insisted on continuing treatment, and the other two stopped treatment. The Tg levels at 1, 3 and 6 months post treatment were 56.26(44.60, 210.50), 53.36(41.25, 203.07) and 54.35(34.71, 223.52) mg/L, respectively, which were lower than the level prior treatment with no significant difference (110.16(49.63, 294.50) mg/L; H=2.42, P=0.490). After 3 months of targeted treatment, the progression-free survival (PFS) rate was 16/17, including 7 patients with partial response (PR), 9 patients with stable disease (SD), and 1 patient with progression of disease (PD). After 6 months of targeted treatment, the PFS rate was 10/17, including 5 patients with PR, 5 patients with SD, and 7 patients with PD. Conclusion:After 3-6 months of targeted treatment, the tumor markers of most patients are decreased with metastases improved, but the adverse events of targeted drugs have a great impact on quality of life in patients with RAIR-DTC.
