Objective:To analyze the current status of clinical research registration on TCM prevention and treatment of malignant tumors in the Chinese Clinical Trail Registry (ChiCTR); To summarize its characteristics and shortcomings.Methods:Clinical studies on the TCM prevention and treatment for malignant tumors registered from the establishment of ChiCTR database to July 15, 2024 were retrieved. Excel 2019 software was used to sort out the data, including basic research information (registration time, registration number status, registration title, test organizer, research implementation location, etc.), design scheme (disease type, research type, intervention measures, sample size, blind method, etc.), research funding or material sources, as well as other information such as human specimen collection and recruitment of research objects. SPSS 27.0 software was used for frequency statistics.Results:A total of 891 registered studies were included, including 783 interventional studies and 108 observational studies; the areas with a large number of registrations were mainly Shanghai, Beijing, Guangdong Province, etc. ; the research funds mainly came from local finance; a total of 46 tumor diseases were involved in the study, with the largest number of lung cancer (209 items), followed by tumor-related syndromes (155 items), colorectal cancer (148 items), and breast cancer (136 items); the type of research design was mainly random parallel control; the main intervention measures were TCM decoction or herbal decoction pieces (373 items), and the dosage form was mostly decoction (216 items), followed by granules (94 items); single-blind or double-blind design was used in 217 registered trials; 663 registration trials involved the collection of human samples.Conclusions:The number of clinical research registrations on the TCM prevention and treatment for malignant tumors is increasing day by day. The shortcomings such as insufficient standardization of research design and lack of research transparency still exists. In the future, TCM researchers need to strengthen cooperation with international traditional medicine clinical trial registry, giving full play to the leading role of standardization of TCM trials, and using registration as a starting point to improve the quality of clinical research.

Objective: To investigate the effect of Ginsenoside Rg1 (GsRg1) on proliferation , migration and osteogenic differentiation of human gingival fibroblasts (HGFs) and its molecular mechanism. Methods: Human gingival fibroblasts (HGFs) were isolated and cultured by tissue block method , and identified by morphology and immunofluorescence. The effect of six concentrations of GsRg1 (0 , 6. 25 , 12. 5 , 25 , 50 , 100 mg/L) on the proliferation of HGFs was detected by CCK⁃8 method. Transwell assay was used to detect the effects of different concentrations of GsRg1 on the migration ability of HGFs. Alkaline phosphatase (ALP) staining was used to detect osteogenic ability. Alizarin red staining was used to observe and quantify calcium nodules. The expression of COL⁃ Ⅰ , OCN and OPN osteogenic genes was detected by qRT⁃PCR. Western blot was used to detect the protein expression of OCN ,OPN , COL⁃ Ⅰ and PI3K/AKT signaling pathway. Results: Compared with the control group , the proliferation ability of HGFs was significantly improved at the concentrations of 12. 5 ,25 ,50 and 100 mg/L GsRg1 (P < 0. 05) , and the proliferation promotion effect of 100 mg/L GsRg1 was the strongest. There was no significant difference between the 6. 25 mg/L GsRg1 group and the control group. After GsRg1 treatment , the migration ability of HGFs was enhanced and showed concentration dependence. Compared with the control group , the activity of ALP in 100 mg/L GsRg1 group significantly increased (P < 0. 01) . Alizarin red staining showed a significant increase in the number of calcium nodules(P < 0. 01) . The mRNA and egg white expression levels of osteogenic genes OCN , OPN and COL⁃ Ⅰ increased (P < 0. 05 ) . The expression levels of p ⁃PI3K and p ⁃Akt were significantly up⁃regulated with time ( P <0. 05) ,while the expression levels of PI3K and AKT had no significant changes. Conclusion GsRg1 can promote the proliferation and migration of HGFs , and 100 mg/L GsRg1 can promote the osteogenic differentiation of HGFs ,which may be related to the activation of PI3K/AKT signaling pathway.

Objective:To evaluate the relationship between early postoperative recovery and frailty after digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in the elderly.Methods:This study retrospectively selected hospitalized patients, aged ≥65 yr, scheduled for elective gastrointestinal endoscopic treatment.Early postoperative recovery time was defined as the period from the end of propofol administration to the achievement of a modified Aldrete score of 9.All the patients were divided into 2 groups according to whether the early recovery time after operation was less than 75%: normal early postoperative recovery time group and delayed early postoperative recovery time group.Frailty was assessed using the frailty phenotype (FP score 0-5), and the patient was diagnosed as frail (FP ≥3) or non-frail (FP 0-2). The age, sex, height, weight, smoking history, American Society of Anesthesiologists (ASA) Physical Status classification, type of operation, and baseline mean arterial pressure and heart rate were recorded.Logistic regression analysis was used to identify the risk factors for delayed early postoperative recovery time after minimally invasive digestive endoscopy under intravenous anesthesia in elderly patients.Results:A total of 214 patients were enrolled and divided into normal early postoperative recovery time group ( n=169) and delayed early postoperative recovery time group ( n=45). There were significant differences in frailty, age, drinking history of more than 10 yr, preoperative ASA Physical Status classification and propofol administration time between delayed early postoperative recovery time group and normal early postoperative recovery time group ( P<0.05). The results of logistic regression analysis indicated that frailty, age, ASA Physical Status classification Ⅲ, and propofol administration time were independent risk factors for the occurrence of delayed early postoperative recovery ( P<0.05). Conclusions:Frailty, age, ASA Physical Status classification Ⅲ and propofol administration time are independent risk factors for delayed early postoperative recovery time following digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in elderly patients.

Objective:To evaluate the effect of tetramethylpyrazine on hippocampal inflammatory responses in rats with sepsis-associated encephalopathy.Methods:Sixty healthy male Sprague-Dawley rats, aged 12-14 weeks, weighing 240-270 g, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (group Sham), sepsis-associated encephalopathy group (group SAE), low-dose tetramethylpyrazine group (group L-TMP), and high-dose tetramethylpyrazine group (group H-TMP). Sepsis-associated encephalopathy was induced by cecal ligation and puncture (CLP) in anesthetized rats.Tetramethylpyrazine 5 and 20 mg/kg were intraperitoneally injected once a day in L-TMP and H-TMP groups, respectively, at 5 days prior to CLP.Morris water maze test was performed at 1-5 days after CLP to assess the cognitive function, and the escape latency and ratio of time spent in the target quadrant were recorded.Five rats were sacrificed at 1 day after CLP, the brains were removed, and the hippocampi were isolated for determination of the contents of interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and IL-6 by enzyme-linked immunosorbent assay.Rats were sacrificed after the end of Morris water maze test, and hippocampi were removed for detection of the expression of Toll-like receptor 1 (TLR1), activated caspase-3, Bax and Bcl-2 by using Western blot. Results:Compared with group Sham, the escape latency was significantly prolonged, the ratios of time spent in the target quadrant were decreased, the expression of TLR1, activated caspase-3 and Bax was up-regulated, and the expression of Bcl-2 was down-regulated in group SAE, group L-TMP and group H-TMP, and the contents of IL-1β, TNF-α and IL-6 were significantly increased in group SAE and group L-TMP ( P<0.05). Compared with group SAE, the escape latency was significantly shortened, the ratio of time spent in the target quadrant was increased, the contents of IL-1β, TNF-α and IL-6 were decreased, the expression of TLR1, activated caspase-3 and Bax was down-regulated, and the expression of Bcl-2 was up-regulated in group L-TMP and group H-TMP ( P<0.05). Conclusion:The mechanism by which tetramethylpyrazine reduces sepsis-associated encephalopathy may be related to inhibiting hippocampal inflammatory responses in rats.

Objective To evaluate the effect of tetramethylpyrazine on autophagy in the hippocam-pal neurons of rats with sepsis-associated encephalopathy. Methods Sixty SPF healthy male Sprague-Daw-ley rats, aged 11-14 weeks, weighing 200-240 g, were divided into 3 groups(n=20 each)using a ran-dom number table: sham operation group(group Sham), sepsis group(group Sep)and tetrameth-ylpyrazine group(group TMP). Sepsis was induced by cecal ligation and puncture(CLP), and group Sham only underwent simple laparotomy. Tetramethylpyrazine 10 mg∕kg was injected intraperitoneally at 1 h before CLP in group TMP. Morris water maze test was performed in 10 rats randomly selected at 12 and 36 h after CLP. Then the rats were sacrificed, and hippocampi were isolated for determination of the expres-sion of microtubule-associated protein 1 light chain 3Ⅰ(LC3Ⅰ), LC3Ⅱ, Beclin-1 and p62 in hipp-ocampal tissues by Western blot, and the LC3Ⅱ∕LC3Ⅰratio was calculated. Results Compared with group Sham, the escape latency was significantly prolonged, the rate of time spent in the target quadrant was decreased, the LC3Ⅱ∕LC3Ⅰratio was increased, the expression of Beclin-1 was up-regulated, and the expression of p62 was down-regulated at 12 and 36 h after CLP in group Sep and group TMP(P<005). Compared with group Sep, the escape latency was significantly shortened, the rate of time spent in the target quadrant was increased, the LC3Ⅱ∕LC3Ⅰratio was decreased, the expression of Beclin-1 was down-regulated, and the expression of p62 was up-regulated at 12 and 36 h after CLP in group TMP(P<005). Conclusion The mechanism by which tetramethylpyrazine reduces sepsis-associated encephalopa-thy is related to inhibiting autophagy in the hippocampal neurons of rats.

Objective To evaluate the effects of different degrees of coagulation disorders after surgery on short-term prognosis in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB).Methods A total of 410 patients of both sexes,aged 18-79 yr,with body mass index of 16-28 kg/m2,of American Society of Anesthesiologists physical status Ⅲ or Ⅳ,scheduled for elective cardiac surgery with CPB,were enrolled in the study.After induction of general anesthesia,the patients were tracheally intubated and mechanically ventilated.Combined intravenous-inhalational anesthesia was used.The patients were divided into 3 groups according to the coagulation function at 6 h after surgery:normal function group (n =55),mild disorder group (n =237) and severe disorder group (n =118).Postoperative mechanical ventilation time,duration of intensive care unit stay,length of hospitalization and complications during hospitalization were recorded.Results Compared with normal function group,the length of hospitalization was significantly prolonged,and the rate of delayed discharge from hospital was increased in mild disorder group,and the ventilation time,duration of intensive care unit stay and length of hospitalization were significantly prolonged,the rate of delayed extubation,rate of prolonged intensive care unit stay and rate of delayed discharge from hospital were increased,and the hepatic and nephritic insufficiency and incidence of re-thoracotomy for bleeding were increased in severe disorder group (P＜0.05),and no significant change was found in the incidence of postoperative complications in mild disorder group (P＞0.05).Conclusion For the patients undergoing cardiac surgery with CPB,postoperative mild coagulation disorders exert no effect on short-term prognosis,however,postoperative severe coagulation disorders produce poor prognosis,and correction of severe coagulation disorders should be taken into account.

Objective To research the effect of regulating systemic inflammatory response by using ulinastatin in elderly patients after sevoflurane inhalation of postoperation cognitive function. Methods 60 patients under went elective abdominal surgery, were randomly double-blinded divided into 2 groups. Every group had 30 patients.Group A accepted continuously intravenousiy infusion ulinastatin 2000 units · kg-1 · h-1 , while group B got equivalent continuously intravenous infusion 0.9% sodium chloride injection. The time point of opening eye, extubation, response and the mini-mental state examination(MMSE) score on different time points were observed. Meanwhile, the changes of concentration of hs-CRP, IL-6,IL-10 were measured. Results Compared with two groups,group A has shorter time on response(F =4.399,P = 0.040). Two both groups had decrease of MMSE score 1 hour after surgery compared with preoperation(t =7. 732,11. 916, both P ＜ 0.01), and the score were less than the preoperative value of more than 2 points which showed cognitive decline in patients. But group A's rate of decline in MMSE score was lower than group B(F = 7. 582 ,P =0.012). Both groups had the MMSE score decline 6h after surgery (t = 4. 606,8. 615, both P ＜ 0.05). Group A's score was less than the preoperative value for less than 2 points, group B's score was lower than the preoperative value for more than 2 points, but the difference between the two groups was not significant (P ＞0. 05). Both groups had higher concentrations of hs-CRP、IL-6 、IL-10 at postoperative 1 d ,3d ,7d (all P ＜ 0.01), peaked at postoperative 1 d, and hadn't come back to the preoperative level 7d*after surgery. In group A, the concentrations of hs-CRP, IL-6 increased (postoperative 1 d,3d), but the rate was lower than the group B (F = 14. 885, P = 0.000;F = 4. 405, P = 0. 040; F = 18. 204, P = 0.000; F = 8. 074, P = 0. 006); while the increased rate of concentration of IL-10 was higher than the group B(F=5.197,P=0.026;F= 12.236,P =0.000). Conclusion Ulinastatin could promote the elderly after sevoflurane inhalation rapid recovery of cognitive function, which may be related to the regulation of systemic inflammatory response.
