Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe dose-limiting adverse event of chemotherapy. Presently, the mechanism underlying the induction of CIPN remains unclear, and no effective treatment is available. In this study, through metabolomics analyses, we found that nab-paclitaxel therapy markedly increased serum serotonin [5-hydroxtryptamine (5-HT)] levels in both cancer patients and mice compared to the respective controls. Furthermore, nab-paclitaxel-treated enterochromaffin (EC) cells showed increased 5-HT synthesis, and serotonin-treated Schwann cells showed damage, as indicated by the activation of CREB3L3/MMP3/FAS signaling. Venlafaxine, an inhibitor of serotonin and norepinephrine reuptake, was found to protect against nerve injury by suppressing the activation of CREB3L3/MMP3/FAS signaling in Schwann cells. Remarkably, venlafaxine was found to significantly alleviate nab-paclitaxel-induced CIPN in patients without affecting the clinical efficacy of chemotherapy. In summary, our study reveals that EC cell-derived 5-HT plays a critical role in nab-paclitaxel-related neurotoxic lesions, and venlafaxine co-administration represents a novel approach to treating chronic cumulative neurotoxicity commonly reported in nab-paclitaxel-based chemotherapy.

Objective To evaluate the efficacy of superselective embolization of the supplying arteries of uterine fibroids under the guidance of 3D angiography in treating uterine fibroids.Methods The clinical data of 14 patients with uterine fibroids,who received interventional embolization therapy at the Third Affiliated Hospital of Zhengzhou University of China,were retrospectively analyzed.Of the 14 patients,5 received microcatheter superselective embolization of the supplying arteries of uterine fibroids after the origin and path of the supplying arteries were clarified by 3D uterine artery angiography(group A),and 9 received embolization of the bilateral uterine arteries up to their main trunks because the fibroids had complex blood supply(group B).The sums of the preoperative and postoperative one-year maximum diameter of uterine fibroids,and the reduction rate of fibroid were statistically analyzed.Results The mean sum of the preoperative and postoperative one-year maximum diameter of uterine fibroids in group A were(85.00±43.35)mm and(35.20±25.96)mm respectively,and the difference was statistically significant(P=0.006),which in group B were(65.00±12.68)mm and(49.44±24.83)mm respectively,and the difference was not statistically significant(P=0.052).There was no statistically significant differences in the mean sum of the preoperative maximum diameter of uterine fibroids and in the postoperative one-year maximum diameter of uterine fibroids between the two groups(P=0.366 and P=0.331).The median reduction rate of uterine fibroids in group A and group B was 62％and 25％respectively,and the difference was statistically significant(P=0.031).Conclusion For the treatment of uterine fibroids,3D angiography-guided superselective embolization of the supplying arteries of uterine fibroids is superior to the embolization of the bilateral uterine arteries in clinical curative efficacy.(J Intervent Radiol,2024,33:533-536)

In September 2020, an elderly patient with cognitive impairment(CI) was admitted in Deparment of Microsurgery, Hangzhou Qiushi Hospital. The patient was in bed and could not answer correctly before surgery. The preoperative Minimum Mental State Examination(MMSE) score was 3(3/30) and the Montreal Cognitive Assessment (MoCA) score was 2(2/30). After completion of preoperative examinations, a 3D microscope combined with fluorescence tracing technique was used to perform deep cervical lymphatic-venous anastomosis at the bilateral cervical Va lymph nodes part: two anastomosis methods were performed, one was end to side anastomosis and the other was end to end anastomosis. The diameters of all anastomotic dilated lymphatic vessels were less than 0.2 mm, the diameters of end-to-side, end to end anastomotic veins were 0.6 mm and 0.2 mm. Short-term postoperative anti-inflammatory treatment was given and a long-term functional rehabilitation training was performed. There were no postoperative complications and the incision healed well. The MMSE scores were 8, 12, 14, 18 point, and the MoCA scores were 8, 9, 11, 13 point. At 3, 30, 90, 180 days after surgery, respectively. Basic cognitive function was restored at 9 months after surgery.

Objective? To understand the influencing factors of the breastfeeding start time of premature newborns after being discharged from the hospital, and to provide the theoretical basis for the effective promotion of breastfeeding for premature infants after discharge. Methods? Using the convenient sampling method, the mothers of premature infants who were hospitalized in Affiliated Children's Hospital of Zhengzhou University from October to December 2017 were selected as the research subjects. A self-designed questionnaire that included general demographic information, breastfeeding knowledge and breastfeeding burden was used in telephone follow-ups, in order to analyze the influencing factors of breastfeeding start time of premature newborns after discharge. SPSS 17.0 was used for data entry and statistical analysis. Among the 100 families that were initially chosen, 2 calls could not be completed, 5 calls were not answered by the parents or too much information was lost, which resulted in a total of 93 valid surveys with the response rate of 93%. Results? Among the 93 cases, 88 newborns were breastfed, and 5 newborns rejected breastfeeding and were put on formula. Only 21.51% of all premature infants were exclusively breastfed. The breastfeeding start time after discharge was 13.0(6.5,28.5)h. 45.45% premature newborns accepted breastfeeding with 3 d after discharge. The premature newborns of different cultures, places of residence, birth weight of premature infants, gestational age, time of first sucking nipples, number of days of NICU hospitalization, knowledge of maternal feeding, feeding burden, whether mothers received breastfeeding guidance during hospitalization, there was a statistically significant difference in the starting time of breastfeeding after discharge (P＜0.05). The results of multiple linear regression showed that the factors that affected the start time of breastfeeding after newborns being discharged from ICU were: birth weight, breastfeeding burden, and the mother's feeding knowledge. Conclusions? The current status of breastfeeding in premature infants should be improved. Nursing personnel should give breastfeeding to premature infants as much as possible during hospitalization while provide psychological guidance and training for breastfeeding for mothers.

Objective To analyze the prevalence and risk factors of anemia in a general population in Kailuan.Methods Working and retired employees m Kailuan Company who had participated in biennial physical examination from 2006-2014 were investigated by questionnaire and blood test.Hemoglobin levels＜ 120 g/L in male and＜ 110 g/L in female are defined as anemia.The trend of prevalence of anemia was analyzed by chi square test.Multivariable logistic regression was used to analyze the factors associated with anemia.Results (1) The biennial prevalence of anemia in Kailuan during 2006-2014 were 3.7％,3.1％,2.4％,1.3％,1.5％.The corresponding proportion were 3.3％,2.3％,1.9％,0.8％,1.0％ in males and 5.3％,5.9％,4.2％,3.1％ and 3.3％ in females,respectively.The differences between males and females were statistically significant (all P＜0.05).The prevalence of anemia declined over time (P for trend＜0.05).(2) The results of multivariable logistic regression showed that aging and elevated hs-CRP were positively associated with anemia,with OR=1.01 (95％CI 1.01-1.02)and 1.03 (95％CI 1.02-1.03),respectively.While male,BMI,physical exercise,smoking,hyperlipidemia were negatively associated with anemia with OR=0.60(95％CI 0.55-0.65),0.99 (95％CI 0.98-0.99),0.91 (95％CI 0.82-0.98),0.87 (95％CI 0.81-0.95)and 0.87(95％CI0.81-0.94),respectively.Conclusions The prevalence of anemia in a large general population in Kailuan has been analyzed.Prevalence of anemia is higher in males than females and declines over time.Several demographic and clinical characteristics are associated with anemia.

Objective:To explore the utilization of and satisfaction at community health service between migrant and non-migrant workers in Shenzhen city. Methods: Random sampling was used and 8000 community residents in Shenzhen city were investigated, and the data was analyzed with SPSS 18. 0. Results:There was statistically signifi-cant difference on the times of seeking community health services last year between migrant workers and non-migrant workers ( P<0. 0001 ) , and the proportion of more than three times service utilization of migrant workers were greater than that of non-migrant workers. The top three elements inpluencing satisfaction at community health service between migrant and non-migrant workers were service attitude ( 73. 29% vs. 73. 46%) , technical level ( 65. 29% vs. 67. 50%), and its convenience of seeking a doctor (63. 16% vs. 64. 98%). 73. 47% of users (migrant workers:74. 16%, non-migrant workers:69. 71%) were willing to accept the system of first contact in community health in-stitutions. Conclusions:The utilization of community health service has increased since implementing the system of first contact in community health institutions. Both migrant workers and non-migrant workers were very satisfied with the community health services, and the differences on satisfaction between the two groups were not significant. It is feasible to gradually promote the system of first contact in community health institutions over China.

Objective To observe the therapeutic efficacy of electroacupuncture with different waves in treating neurogenic bladder due to spinal cord injury (SCI). Method Totally 108 patients with SCI-induced neurogenic bladder were randomized into 3 groups, 36 cases in each group. Same acupoints were selected for the three groups, but continuous wave, sparse-dense wave and discontinuous wave were respectively used after needling qi arrival. The symptoms score and urodynamic indexes were observed before and after the intervention. Result The total effective rate was 80.6%in the sparse-dense wave group, better than that in the continuous wave group and discontinuous wave group. The sparse-dense wave group produced a more significant effect in reducing the urethral closure pressure, abdominal pressure, functional urethral length, and urethral control length (P<0.05); there were no significant inter-group differences in comparing the effect in increasing the urinary flow rate (P>0.05). The discontinuous wave group produced a more significant effect in increasing the bladder pressure (P<0.05,P<0.01); the effect in lowering the bladder pressure was more significant in the continuous wave and sparse-dense wave groups than in the discontinuous wave group (P<0.01). Conclusion The three types of electroacupuncture wave can produce different regulatory effects on the body. The continuous wave is the most adaptable one but plays the least effect;the sparse-dense wave is closer to bioelectricity of human body and produces the most significant effect;the discontinuous wave produces the most significant effect in activating nerves and muscles, as well as in improving bladder weakness.

To investigate the role of Toll like receptor (TLR) in the activation of dendritic cells (DC) during early Plasmodium yoelii infection of the lethal strain 17XL (P.y 17XL), susceptible BALB/c and resistant DBA/2 mice were infected by i.p.injection of the P.y l7XL-parasitized erythrocytes, and the parasitemia of individua1 mice was monitored by the microscopic examination of blood smear stained with Giemsa.Mice from norma1 and infected groups were sacrificed on 0,3 and 5 days post-infection to collect their spleen cells.And the expressions of TLR-9 and TLR-4 on the cell surface of DCs in spenonocytes of these two strains of mice were assayed by applying flow cytometry to quantitatively analyze the percentages of CD11c+TLR9+ DCs and CD11c+TLR4+ DCs. It was found that the population of CD11c+DCs expressing TLR9 was significantly increased on day 3 and peaked on 5 p.i. in BALB/c (P<0.01) and DBA/2 mice(P<0.01). However, there was no statistical significance between these two strains of mice. Meanwhile, there was no change on the population of CD11c+ DCs expressing TLR4 in BALB/c and DBA/2 mice. These results indicate that TLR9 may contribute to the DC activation during early stages of P.y17XL infection.
