Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

Objective:To assess the effect of mild intraventricular hemorrhage（IVH）on the early motor development of infants at high risk of brain injury,and to guide the intervention according to its characteristics.Methods:A retrospective cohort study was conducted to select neonates discharged from the Neonatal Unit of Xi 'an Children 's Hospital from February 1，2022 to March 31，2023，with one or more high-risk factors of brain injury.The patients were assigned to low-grade IVH group and no IVH group according to ultrasound diagnosis.The research subjects exclucled other brain injury diseases besides mild IVH.Motor development was assessed using test of infant motor performance(TIMP)，reflecting performance in head control，auditory and visual responses，defensive movements，trunk movements，limb movements，and more.Both groups completed TIMP assessment between discharge and 16 weeks of the corrected age(CA).The differences of TIMP scores between two groups were compared . Results:A total of 329 neonates at high risk for brain injury were recruited，including 98 cases with grade Ⅰ-Ⅱ IVH（low-grade IVH group）diagnosed through brain ultrasonography and 231 controls(no IVH group).The Z scores of TIMP in the low-grade IVH group were lower than that in no IVH group（-0.25 ±0.87 vs.0.03 ±0.71， P=0.015）.The risk factors of brain injury were matched for further comparison.At CA2-5 weeks，the scores in low-grade IVH group of TIMP total scores（74.10 ±12.28 vs.84.24 ±7.71），observation items（10.57 ±1.47 vs.11.24 ±1.29），elicitation（63.17 ±12.13 vs.73.00 ±7.36），sitting（9.14 ±2.90 vs.11.65 ±3.26），supine（22.07 ±4.73 vs.24.79 ±3.55），prone position（10.35 ±3.74 vs.12.82 ±3.15）and lateral position（4.00 ±2.85 vs.5.48 ±2.13）were significantly lower than those in no IVH group（ P<0.05）.At CA6-9 weeks，the scores in low-grade IVH group of sitting position（10.44 ±4.01 vs.12.96 ±3.02），supine position（24.04 ±4.60 vs.26.83 ±3.53），lateral position（4.83 ±2.53 vs.6.25 ±2.6）were significantly lower than those in no IVH group（ P<0.05）.At CA12-15 weeks，the low-grade IVH group showed significant differences in TIMP total score（104.00 ±12.98 vs.114.10 ±13.16），elicitation（92.00 ±12.64 vs.102.00 ±13.10），sitting（17.00 ±3.50 vs.19.13 ±3.55）and lateral position（7.35 ±2.14 vs.9.00 ±2.37）compared with those from no IVH group（ P<0.05）. Conclusion:Mild intraventricular hemorrhage affected the early motor development of high-risk infants with brain injury，mainly manifested as a lag in the ability of head control at CA2-5 weeks，and the trend continued until CA12-15 weeks.Early monitoring of motor ability and intervention of head control ability should be carried out in high-risk children with mild intraventricular hemorrhage.

Objective:To investigate the characteristics of early motor development in small for gestational age (SGA) infants at high risk of brain injury.Methods:This study retrospectively enrolled a total of 81 SGA infants and appropriate for gestational age (AGA) infants who were at high risk of brain injury and attended outpatient follow-up visits in Xi'an Children's Hospital from February to October 2022. Seventeen SGA infants (SGA group) and 24 AGA infants (AGA group) were assessed for motor development using the Test of Infant Motor Performance (TIMP) at 2-5 weeks of corrected age (CA) and 20 SGA infants (SGA group) and 20 AGA infants (AGA group) were assessed at 14-17 weeks of CA. Independent samples t-test, rank-sum test, and Chi-square test were used to compare the demographic characteristics, high-risk factors of brain injury, and TIMP scores between the two groups. Results:At 2-5 weeks and 14-17 weeks of CA, the birth weights of SGA group were both less than those of AGA group [(1 817.1±440.3) vs. (2 630.0±560.9) g, t=－4.98; (1 752.0±434.4) vs. (2 226.3±699.8) g, t=－2.58; both P<0.05], but there were no significant differences in gestational age at birth or high-risk factors of brain injury between the two groups (all P>0.05). (1) At 2-5 weeks of CA: SGA group had lower total TIMP score [(71.6±13.7) vs. (80.5±11.5) scores, t=－2.26, P=0.029], elicited item score [61.0 scores (41.0-85.0 scores) vs. 69.1 scores (49.0-96.0 scores), Z=－2.15, P=0.037], sitting position score [8.8 scores (3.0-19.0 scores) vs. 11.2 scores (5.0-22.0 scores), Z=－2.07, P=0.038], and prone position score [(9.8±3.1) vs. (12.3±3.1) scores, t=－2.19, P=0.034] when compared with AGA group. (2) At 14-17 weeks of CA: The standing position score of the SGA group was lower than that of the AGA group [6.5 scores (4.0-11.0 scores) vs. 7.7 scores (2.0-11.0 scores), Z=－2.05, P=0.040], but no statistical difference was observed in the total TIMP score or the scores of sitting, supine, prone, turning, and lateral positions between the two groups (all P>0.05). Conclusion:Early motor performance of SGA infants is inferior to AGA infants before five months of age, which is embodied in the poor head control at 2-5 weeks of CA that further affects the stability of standing posture in them at 14-17 weeks of CA.

Objective By population survey,to explore the epidemiological characteristics of gastric precancerous lesions in Lishui District of Nanjing and provide objective basis for the prevention and treatment of early gastric cancer.Methods From July 2021 to December 2022,21 977 patients who received endoscopy and/or 13C-UBT in Lishui District People's Hospital and 6 medical community units in Nanjing City were retrospectively analyzed for demography characteristics,detection rate of gastric precancerous lesions,and H.Pylori infection rate.Results(1)590 cases of gastric precancerous lesions were detected(detection rate 2.68%);(2)The total detection rate of precancerous lesions and three pathological types in males were all higher than those in females(all P<0.001);(3)The minimum age for the total detection rate of precancerous lesions in males and the mini-mum age for each pathological type were lower than in females(P<0.001,0.009,0.005,0.002);(4)The popu-lation total H.pylori infection rate was 23.10%,the H.pylori infection rate in patients with precancerous lesions was higher than that in non-precancerous lesions(P<0.001),both H.pylori infection rate of male and female in precancerous lesions were all higher than those of non-precancerous lesions of the same sex(all P<0.001),in addition,the H.pylori infection rate of male whether in precancerous or non-precancerous lesions was higher than that of female(all P<0.001);(5)The precancerous lesions detection rate in male,female,and the overall age range of 20～29 to 70～79 years is positively correlated with age growth(P<0.001),and rapidly decreases after the age of 79,the of H.pylori infection rate was also positively correlated with age growth(P<0.001),and the trend of age change(P<0.001)was parallel to the precancerous lesions detection rate.Conclusions The detec-tion rate of gastric precancerous lesions in this region is above the average level in China;the total H.pylori infec-tion rate is at a relatively low level in China;the H.pylori infection rate is parallel to the age trend of the detection rate of gastric precancerous lesions,and increases with age.

Objective To systematically evaluate the clinical efficacy of treatment based on intestine in the sepsis induced acute lung injury/acute respiratory distress syndrome(ALI/ARDS)under the traditional Chinese medicine theory"interior and exterior relationship between the lung and large intestine",and to provide evidence-based reference for clinical practice.Methods A computerized search of CNKI,Wanfang database,VIP database,China Biology Medicine disc(CBMdisc),Embase database of Dutch medical abstracts,PubMed database,Cochrane library database was performed to identify randomized controlled trial(RCT)that used the Tongfu method as an intervention for the treatment of ALI/ARDS induced by sepsis,published from the database establishment until October 8,2020.The control group was treated with conventional western medicine,and the test group was treated with the combination of Tongfu method and conventional western medicine.Screening of the literature and data extraction for those that met the inclusion criteria were performed by 2 investigators.The modified Jadad scale was used for quality assessment,and RevMan 5.4 and Stata 16.0 software were used for Meta analysis of the data.Results Thirteen articles were finally included,all of which were single center RCT studies,including 7 articles with≥4 points and 6 articles with<4 points.A total of 579 patients were included,290 in the test group and 289 in the control group.Meta-analysis showed that combined Tongfu treatment significantly increased the ALI/ARDS patient caused by sepsis oxygenation index[PaO2/FiO2;mean difference(MD)= 62.55,95%confidence interval(95%CI)was 55.74 to 69.37,P<0.05],reduced the levels of interleukin-6(IL-6;MD =-29.70,95%CIwas-48.34 to-11.06,P<0.05),tumor necrosis factor-α(TNF-α;MD=-2.94,95%CIwas-5.28 to-0.59,P<0.05),procalcitonin(PCT;MD =-1.34,95%CI =-2.17 to-0.51,P<0.05)and C-reactive protein(CRP;MD =-22.41,95%CIwas-36.52 to-8.29,P<0.05),reduced mechanical ventilation time(MD=-2.26,95%CIwas-2.86 to-1.66,P<0.05)and hospitalization time in intensive care unit(ICU;MD=-4.15,95%CIwas-7.47 to-0.84,P<0.05),reduced the 28-day mortality[relative risk(RR)= 0.43,95%CI was 0.24 to 0.76,P<0.05]and acute physiology and chronic health status scoreⅡ(APACHEⅡ;MD =-3.53,95%CI was-5.41 to-1.64,P<0.05).Conclusion Treatment based on intestine is valuable for reducing the condition and improving the prognosis of ALI/ARDS patients caused by sepsis,but further high-quality RCT studies are still needed to verify its efficacy and provide more accurate evidence-based evidence for clinical treatment.
