OBJECTIVE:To observe the occurrence of paclitaxel(PTX)-induced muscle soreness and therapeutic efficacy and safety of diclofenac sodium. METHODS:Among 84 patients with malignant tumor receiving PTX chemotherapy,56 patients suf-fered from PTX-induced muscle soreness,among which 22 female patients suffered from medium and severe muscle soreness and then were randomly divided into group A and B,with 11 cases in each group. Group A was given Diclofenac sodium sustained-re-lease tablet 75 mg orally,once a day;group B was given Paracetamol and tramadol hydrochloride tablets one tablet orally,once a day,and then given Promethazine hydrochloride injection 100 mg subcutaneously,2-3 times a day when muscle soreness could not be born. Treatment course of both groups lasted for 5 d. The distribution of muscle soreness were observed. The onset time and dura-tion of muscle soreness were also observed as well as pain relief and the occurrence of ADR in group A and B. RESULTS:Among 84 cases,the incidence of muscle soreness was 66.67%,among which mild pain accounted for 23.81%,moderate pain accounted for 13.10%,and severe pain accounted for 29.76%. Among 56 patients with muscle soreness,earliest muscle soreness occurred on the day of medication,and most of muscle soreness occurred on 1-3 days after medication,mainly manifesting as sore,activity limitation when severe,associated with fatigue. The pain relief rate of group A and B were 100%,but the incidence of adverse re-actions in group A was significantly lower than group B,with statistical significances(P<0.05).CONCLUSIONS:Diclofenac sodi-um is similar to paracetamol and tramadol hydrochloride in the treatment of PTX-induced muscle soreness,but it is better than paracetamol and tramadol hydrochloride in safety.

Objective To assess the value of CMV viral load test in the diagnosis and prognostic judgment of infantile cytomegalovirus infection with whole blood and urine specimens. Methods 50 infants with active CMV infection were selected, which pp65 antigen was positive in serological detection and either CMV-IgM positive or the titer of CMV-IgG ≥40. The viral load in whole blood and urine specimens was detected before and after a course of preemptive ganciclovir treatment and the pp65 antigen was determined after treatment. Results 98% patients were manifested as cytomegalovirus viral load quantitative measurement in whole blood positive before the treatment, while 14% after. The positive ratio of pp65 assay after therapy was 6%. And there was no significant difference between the results of the two kinds of detection methods measurement in urine before and after treatment was 98% and 90%, respectively. The results of urinary viral load quantitative detection did not coincide with clinical characteristics of CMV infection (P＜0.05,Sp＝0.11,PVP＝0.55, (Youden's index)＝0.09). Conclusions Good coincidence could be found between CMV-DNA quantitative measurement in whole blood and pp65 antigenemia assay. And the former could be used as a diagnostic index of CMV positive infection. While single urinary viral load quantitative detection had no significance for the distinction between active and latent CMV infection and dynamic monitoring of CMV treatment.

Objective To evaluate the potential risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City,so as to provide evidences for establishing a post?transmission surveillance system for schistosomiasis in marsh?land regions. Methods The water infectivity,floating boatmen and fishermen infection,reservoir host infection and wild feces contamination were investigated in five districts/counties along the Yangtze River in Yangzhou City,including Guangling,Hanji?ang,Jiangdu,Yizheng and Development Zone,and the transmission factors and risky characteristics were assessed after inter?ruption of schistosomiasis transmission in marshland regions. Results A total of 15 key water regions were identified in the area along the Yangtze River in Yangzhou City in 2015. A total of 1 500 sentinel mice were placed,after breeding,their overall sur?vival rate was 99.33%;1 490 were dissected,with no schistosome infection. Of the 5 576 floating boatmen and fishermen exam?ined,no schistosome infection was observed,and among the 3 566 domestic animals(including 171 cattle,1 895 sheep and 1 500 pigs),no infections were detected. During the period between January and March,2016,there were 3 200 mouse traps placed on 8 marshlands,and 62 wild mice were captured from 6 marshlands,with a capture rate of 1.94%,and no schistosome?infected wild mice were seen. In addition,there were 35 pieces of fresh wild feces captured from 7 marshlands,including 11 pieces of bovine feces(31.43%),17 pieces of sheep feces(48.57%),2 pieces of dog feces(5.71%)and 5 pieces of other feces (14.29%),and no infections were detected. Conclusions There is a low risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City. However,the contamination of feces from bovine and sheep that are freely pastured on marshlands is a big threat to schistosomiasis control.

Purpose: The aim of this study was to assess carotid stiffening in a pre-hypertensive (PHT) population using ultrafast pulse wave velocity (ufPWV). Methods: This study retrospectively enrolled 626 individuals who underwent clinical interviews, serum tests, and assessments of the systolic blood pressure (SBP), diastolic blood pressure (DBP), carotid intima-media thickness (cIMT), pulse wave velocity-beginning of systole (PWV-BS), and pulse wave velocity-end of systole (PWV-ES) between January 2017 and December 2021. The patients were divided into three groups according to their blood pressure (BP)—normal BP (NBP): SBP <130 mmHg and DBP <80 mmHg (n=215); PHT: 130 mmHg≤SBP<140 mmHg and/or 80 mmHg≤DBP<90 mmHg (n=119); hypertensive (HT): SBP ≥140 mmHg and/or DBP ≥90 mmHg (n=292). Correlation analyses and comparisons were performed among the groups and in the cIMT subgroups (cIMT ≥0.050 cm and <0.050 cm). Results: cIMT and PWV-ES significantly differed among the BP groups (P<0.05). The BP groups had similar PWV-BS when cIMT <0.050 cm or cIMT ≥0.050 cm (all P>0.05). However, the NBP group had a notably lower PWV-ES than the PHT (P<0.001 and P=0.024) and HT (all P<0.001) groups in both cIMT categories, while the PWV-ES in the PHT group were not significantly lower than in the HT group (all P>0.05). Conclusion Carotid morphological and biomechanical properties in the PHT group differed from those in the NBP group. ufPWV could be used for an early evaluation of carotid stiffening linked to pre-hypertension.

Objective To evaluate the feasibility of quantitative evaluation of fallopian tubes patency by the rising slope of pressure curve produced by bolus injection using a liquid diagnostic apparatus in the four-dimen-sional hysterosalpingo-contrast sonography. Methods A total of 205 patients with infertility were collected for four-dimensional hysterosalpingo-contrast sonography. In the examination,the contrast medium concentration,the liquid volume of the liquid diagnostic apparatus and the speed of the liquid were stationary calculated. The rising slope of the curve was calculated according to the real-time pressure curve produced by the contrast agent injection process. According to the hysterosalpingo-contrast sonography examination's results ,patients were divided into one side patency group,one side partial obstruction group and one side obstruction group. The correlation between the slope and the patency of the fallopian tube was analyzed by binary logistic regression. Results Binary logistic regression showed that the slope and fallopian tube patency had good correlation(all P < 0.05)between one side patency group and one side obstruction group,and also between one side partial obstruction group and one side obstruction group;but had no correlation between one side patency group and one side partial obstruction group(regression coefficient P>0.05,regression constant P=0.000). Conclusion The slope of pressure curve produced by four-dimensional hysterosalpingo-contrast sonography can be used to assess the patency of fallopian tubes quantitatively. It is a new auxiliary index for evaluating the patency of fallopian tubes.

Purpose: The present study investigated the association between Systematic COronary Risk Evaluation (SCORE)-estimated cardiovascular risk and carotid stiffening in a middle-aged population using ultrafast pulse wave velocity (ufPWV). Methods: This study enrolled 683 participants without known cardiovascular disease or diabetes mellitus who underwent ufPWV measurements. Clinical interviews, physical examinations, laboratory findings, carotid intima-media thickness (cIMT), pulse wave velocity (PWV) at the beginning of systole (PWV-BS), and PWV at the end of systole (PWV-ES) were assessed. Each participant underwent an assessment of SCORE risk based on major cardiovascular risk factors (CVRFs), including age, sex, smoking, systolic blood pressure (SBP), and total cholesterol (TC). Crude and adjusted odds ratios (ORs) with 95% confidence intervals and ordinal logistic regression were used. Overall CVRFs were adjusted to assess ORs. Results: cIMT and carotid stiffening in PWV-BS and PWV-ES were significantly different between sex subgroups (all P<0.05), but only PWV-ES increased gradually in age and SCORE-estimated risk subgroups (all P<0.05). Compared with cIMT (r=0.388, P<0.001) and PWV-BS (r=0.159, P<0.001), PWV-ES was more strongly correlated with SCORE categories (r=0.405, P<0.001). Higher PWV-ES values were associated with SCORE categories independently of sex, SBP, TC, and smoking in moderate-risk and high-risk subgroups (OR, 1.63; P<0.001 and OR, 2.12; P=0.024, respectively), but were not independent of age in all risk subgroups (all P>0.05). Conclusion Carotid stiffening quantified by ufPWV is linked to SCORE categories, and elevated PWV-ES may aid in cardiovascular risk stratification.
