Sesquiterpenoids are natural compounds composed of 15 carbon atoms， which can be divided into sesquiterpene alcohols， ketones， lactones， aldehydes， and carboxylic acids according to oxygen groups. These compounds are widely distributed in nature， and their physiological activities are diverse. For example， many sesquiterpenes with potential anticancer effects have been found for anti-tumor effects， including cytotoxicity， antioxidant， immune regulation， cell proliferation， and so on. In addition， some sesquiterpenoids have good application prospects in antibacterial， anti-inflammatory， and anti-cardiovascular diseases. Malignant tumors， inflammation， bacterial diseases， and cardiovascular diseases are the main diseases that cause human death， and natural products have unique advantages in the treatment of these diseases. Therefore， the development of new drugs that are easy to promote has become a new research hotspot. In this paper， the sesquiterpenes extracted from the natural components of Chinese herbs and plants with anti-tumor， anti-inflammatory， antibacterial， and anti-cardiovascular activities， such as Xanthium， Atractylodes， Convolvulus， Acanthium， Ligularia， Artemisia， Ligularia， Ligularia， Labiaceae Mint， Acanthophyllum， Turmeria， Ginger， and other Chinese herbs and plants， were discussed. The biological activities and related mechanisms of this compound were reviewed， which provided a reference for further research and clinical application of sesquiterpenes.

Objective To investigate the appropriate venous access for obese patients undergoing metabolic and bariatric surgery by comparing the clinical outcomes of different lengths of peripheral intravenous catheters.Methods Inpatients who underwent bariatric surgery in a tertiary hospital in Zhejiang from August 2022 to December 2022 were selected as the study population using a fixed-point continuous convenience sampling method.A stratified block randomisation method was used to divide the group into an experimental group 1(mini-midline catheters),an experimental group 2(midline catheters)and a control group(short peripheral intravenous catheters,Short PIVCs).The incidence of catheter-related complications,the rate of extubation due to complications,the duration of catheter retention,the time to first catheter-related complication were compared in the 3 groups.Results A total of 186 patients were included,with 62 patients in each group.The overall incidence of catheter-related complications in experimental group 1,experimental group 2,and control group were 25.81％,8.06％,and 58.06％.The extubation rates due to complications were 19.35％,4.84％,and 41.94％,and the duration of catheter retention was 7.00(6.00,7.00)d,7.00(6.00,7.00)d,6.00(3.00,6.25)d.The differences were statistically different(P＜0.05)when comparing the 3 groups.Among them,the differences in the overall incidence of catheter-related complications and the rate of extubation due to complications were statistically significant when comparing experimental group 1 with the control group,experimental group 2 with the control group,and experimental group 1 with experimental group 2(P＜0.017);the duration of catheter retention in both experimental group 1 and experimental group 2 were higher than it in the control group,and the differences were statistically different(P＜0.017).Conclusion The complication rate of mini-midline catheters and midline catheters is lower than that of short ones,and the indwelling time is consistent with the perioperative period of metabolic and bariatric surgery,which is suitable for use in patients undergoing metabolic and bariatric surgery.

Objective:To explore the effects of infusion of irritant medications on the patients with midline catheter based on propensity score matching method and provide reference for medications infusion through midline catheter.Methods:Through a retrospective cohort study, the clinical data of 1 539 patients with midline catheter placement in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from March 2019 to October 2022 were retrospectively analyzed, and the patients were divided into irritant medications group ( n=1 120) and non-irritant medications group ( n=419) according to the characteristics of the medications they were infused with, and then compared the patients of the two groups with midline catheter-related complications and catheter indwelling time based on the propensity score matching. Results:Among 1 539 patients, there were 656 males and 883 females, aged 18-92 (59.30 ± 18.76) years old. Before propensity score matching, there were statistically significant differences in age: (58.09 ± 18.72) years old, (62.55 ± 18.50) years old; hypertension:496 cases, 210 cases; diabetes:266 cases, 129 cases; white blood cell count:7.50(5.50, 9.70) × 10 9/L, 7.00(5.10, 9.50) × 10 9/L between the irritant medications group and non-irritant medications group ( t=4.18, χ2=4.18, 7.92, Z=-1.98, all P<0.05). After propensity score matching, there were 412 patients in the irritant medications group and 412 patients in the non-irritant medications group, and there was no significant difference in the general data between the two groups (all P>0.05). After propensity score matching, the rates of oozing, bleeding, catheter occlusion, catheter-related thrombosis, catheter dislodgement and total catheter complications between the two groups showed no statistically significant difference (all P>0.05). The catheter indwelling time in the irritant medications group was 10.00 (5.25, 16.75) days, which was longer than that in the non-irritant medications group for 6.00 (4.00, 11.00) days, the difference was statistically significant ( Z=-7.25, P<0.05). Conclusions:Infusion of irritant medications has no effect on the outcome of midline catheter, but monitoring and catheter maintenance should be strengthened in order to reduce the occurrence of cutheter related complications.

Objective To compare the effects of mini-midline catheters that were placed in different sites.Methods The inpatients of a tertiary general hospital in Zhejiang Province from October 2023 to January 2024 were selected as the study subjects using a fixed point continuous convenience sampling method.The patients were divided into 2 groups by simple random grouping method.The experimental group had a mini-midline catheter placed in the upper arm,and the control group had a mini-midline catheter placed in the forearm.The incidence of catheter-related complications,the puncture success rate with one-attempt,the total procedure time,the time of the first occurrence of catheter-related complications,the rate of removal due to complications,and the indwelling catheter duration were compared between the 2 groups.Results A total of 121 patients were included,including 64 in the experimental group and 57 in the control group.The incidence rates of catheter-related complications in the experimental group and the control group were 29.69％and 66.67％;the times of the first occurrence of catheter-related complications were 167(122,220)h and 104(73,168)h;the rates of removal due to complications were 17.19％and 42.11％;the indwelling catheter duration was 171(124,258)h and 120(92,187)h;the differences between the 2 groups of these outcomes were statistically significant(P＜0.05).The puncture success rates with one-attempt in the experimental group and the control group were 96.88％and 96.49％;the total procedure times were 352(296,446)s and 370(295,430)s;the differences between the 2 groups of these outcomes were not statistically significant(P＞0.05).Conclusion Mini-midline catheters inserted in the upper arm can reduce the incidence of catheter complications and the rate of removal due to complications,prolong the time of the first occurrence of catheter-related complications and the indwelling catheter duration.

Objective:To investigate the value of ultrasound and Ki-67 for early predicting pathological complete response (pCR) of triple negative breast cancer(TNBC) after neoadjuvant chemotherapy (NAC).Methods:Retrospective analysis was performed in 190 patients with TNBC who underwent surgery after NAC treatment at the Cancer Hospital of Fudan University from January 2019 to December 2022. All patients underwent ultrasound examination before and after 2 and 4 cycles of NAC treatment. According to the operation pathological results after NAC, the patients were divided into pCR group and non-pCR group. The differences in ultrasound and Ki-67 parameters were compared between the pCR and non-pCR groups, and binary Logistic regression analysis was performed to determine the independent predictors for pCR. The ROC curve was plotted to evaluate the diagnostic efficacy.Results:Tumor maximum diameter, relative change rates of tumor maximum diameter after 2-cycle and 4-cycle NAC (ΔD2, ΔD4), relative change rate of lymph node short diameter after 2-cycle NAC (ΔS2), T-stage, N-stage and Ki-67 showed statistically significant differences between the pCR group and the non-pCR group (all P<0.05). Logistic regression analysis showed that ΔD4, T-stage, N-stage and Ki-67 were independent predictors for pCR ( OR=1.029, P=0.011; OR=0.300, P=0.009; OR=0.653, P=0.048; OR=1.028, P=0.001). The area under the curve (AUC) of pCR was 0.804 (95% CI=0.742-0.866), the sensitivity and specificity were 67.5% and 83.2% respectively. Conclusions:The combination parameters of ΔD4, T-stage, N-stage and Ki-67 have certain clinical value for predicting pCR of TNBC.

ObjectiveTo investigate the effect of direct-acting antiviral (DAA) on the recurrence of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) after curative treatment. MethodsPubMed, Web of Science, Cochrane Library, CNKI, CBM, Wanfang Data, and VIP were searched for the clinical studies of DAA and the recurrence of HCV-related HCC published up to April 2020. Stata 14.0 software was used to perform the meta-analysis. The Cochran Q test was used to evaluate heterogeneity between studies; the fixed effects model was used for non-heterogeneous data, and the random effects model was used for heterogeneous data. The Egger regression method or the Begg rank correlation method was used to evaluate the presence or absence of publication bias. ResultsA total of 10 articles (11 studies) were included in our study, among which 8 articles (9 studies) compared the effect of DAA versus the absence of anti-HCV therapy on the recurrence of HCC after curative treatment. There were 991 patients in DAA group and 808 patients in untreated group. The results of the meta-analysis showed that DAA reduced the recurrence rate of HCC after curative treatment in patients with HCV infection (hazard ratio ［HR］=0.42, 95% confidence interval ［CI］: 0.28?0.36, P＜0.001). Three articles compared the effect of DAA versus interferon for the treatment of hepatitis C on the recurrence of HCC after curative treatment, with 267 patients in DAA group and 212 in interferon group, and the results of the meta-analysis showed that DAA and interferon had a similar effect on the recurrence rate of HCV-related HCC (HR=0.85, 95% CI: 0.64-1.15, P=0.298). ConclusionBoth interferon and DAA can significantly reduce the recurrence risk of HCV-related HCC after curative treatment, with no significant difference between them.

Pulmonary surfactant (PS) is synthesized and secreted by alveolar epithelial type II (AEII) cells, which is a complex compound formed by proteins and lipids. Surfactant participates in a range of physiological processes such as reducing the surface tension, keeping the balance of alveolar fluid, maintaining normal alveolar morphology and conducting host defense. Genetic disorders of the surfactant homeostasis genes may result in lack of surfactant or cytotoxicity, and lead to multiple lung diseases in neonates, children and adults, including neonatal respiratory distress syndrome, interstitial pneumonia, pulmonary alveolar proteinosis, and pulmonary fibrosis. This paper has provided a review for the functions and processes of pulmonary surfactant metabolism, as well as the connection between disorders of surfactant homeostasis genes and lung diseases.
