Objective To investigate the diagnostic value and clinical significance of hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)combined with interleukin-6(IL-6)in children with severe hand-foot-mouth disease.Methods A total of 62 children hospitalized in our hospital from January 2022 to December 2022 were collected as research objects.According to the severity of infection,they were divided into observation group(severe infection group)with 29 cases and control group(mild infection group)with 33 cases.The differences of general data,total leukocyte count,neutrophil count,lymphocyte count,platelet count,hs-CRP,PCT,IL-6 and creatine kinase isoenzyme(CK-MB)between the two groups and their clinical applications were analyzed and compared.Results The total white blood cell count,neutrophil count,lymphocyte count,hs-CRP,PCT and IL-6 in the observation group were higher than those in the control group,and the difference has statistically significant.Receiver operator characteristic(ROC)curve analysis of hs-CRP predicted the sensitivity and specificity of severe infection of hand-foot-mouth disease were 79.3%and 93.9%(95%CI:0.852-10.985,P<0.05);The sensitivity and specificity of PCT were 93.1%and 84.8%(95%CI:0.907-1,P<0.05);The sensitivity and specificity of IL-6 were 96.6%and 87.9%(95%CI:0.945-1,P<0.05).Conclusions In hand-foot-mouth classification,PCT and IL-6 are highly sensitive.Although hs-CRP is less sensitive than the former,its specificity is higher than the former.Therefore,the combination of hs-CRP,PCT and IL-6 has higher value for hand-foot-mouth classification.

Objective To explore the effect of Lee-Silverman voice treatment (LSVT) on language re-habilitation of dysarthria in Parkinson's disease (PD).Methods A total of 84 patients with PD dysarthria ad-mitted to our hospital from February 2019 to February 2022 were selected as the research objects.According to the random number table method,they were divided into observation group and control group,with 42 cases in each group.The control group received routine speech rehabilitation training,and the observation group re-ceived LSVT for four weeks.The scores of Western Aphasia Battery (WAB) and Aphasia Quotient (AQ) be-fore and after intervention were compared between the two groups,and the differences of electroglottographic parameters such as jitter,F0,shimmer,normalized noise energy (NNE) and harmonic noise ratio (HNR) were compared between the two groups.Results Before intervention,there was no significant difference in WAB scores (listening comprehension,repetition,spontaneous speech,naming) and AQ scores between the two groups (P>0.05).After intervention,the above scores of the two groups were significantly improved,and the observation group was higher than the control group,the difference was statistically significant (P<0.05). Before intervention,the jitter,F0,shimmer,NNE,HNR of vowels "a""i""u" in the two groups were not sta-tistically significant (P>0.05).After intervention,the above-mentioned electroglottic parameters of the two groups were significantly improved.The jitter and NNE of vowels "a""i""u" in the observation group were lower than those in the control group,and the HNR was higher than that in the control group,the differences were statistically significant (P<0.05).Conclusion LSVT can improve the electroglottographic parameters and speech function of patients with PD dysarthria,and the language rehabilitation effect of PD dysarthria is obvious.

OBJECTIVE: To observe the effects of acupuncture on neurologic function and serum inflammatory factors in patients after thrombolysis in acute ischemic stroke (AIS). METHODS: A total of 102 AIS patients with onset to treatment time (OTT) ≤3 h were randomly divided into an observation group and a control group, 51 cases each group. In the control group, thrombolysis and conventional medical treatment were applied. On the basis of the treatment as the control group, acupuncture at Shuigou (GV 26), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), etc. was applied in the observation group, 30 min each time, once a day. Both groups were treated for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Rankin scale (mRS), modified Barthel index (MBI) and serum level of homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP) were compared, and the clinical efficacy was evaluated in the two groups. RESULTS: After treatment, the scores of NIHSS, mRS and serum level of Hcy, hs-CRP were decreased compared with those before treatment (P<0.05), while the MBI scores were increased (P<0.05) in the two groups. The scores of NIHSS, mRS and serum level of Hcy, hs-CRP in the observation group were lower than those in the control group (P<0.05, P<0.01), the MBI score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 88.2% (45/51) in the observation group, which was superior to 70.6% (36/51) in the control group (P<0.05). CONCLUSION Acupuncture could promote the recovery of neurologic function in patients after thrombolysis in AIS, improve the ability of daily living, which may be related to reducing the level of inflammatory factors, thus inhibiting inflammatory response and improving cerebral ischemia reperfusion injury.

【Objective】 To study the detection performance of HBsAg single-ELISA-reactive samples of blood donors. 【Methods】 Two kinds of ELISA reagents from different manufacturers (named as reagents A and B) were used for HBsAg screening. A total of 276 samples, from January 2017 to May 2021, with HBsAg single-ELISA-reactive results were collected for further nucleic acid detection technology (NAT) and chemiluminescence immunoassay (CLIA) testing, to undergo HBV-DNA and five hepatitis B tests, respectively. The relationship between HBsAg single-ELISA-reactivity, NAT and CLIA was statistically analyzed. 【Results】 Among the 276 HBsAg single-ELISA-reactive samples, 14 were NAT reactive, with the positive rate of 5.07% (14/276). Fisher′s exact test was used to compare the compliance of reagents A and B with NAT reactivity, and the difference was not statistically significant (P<0.05). Among 14 HBsAg+ /NAT+ samples retested by CLIA, 2 were HBsAg reactive(14.29%, 2/14), 13 were anti-HBc reactive (92.86%, 13/14), 9 had the quantitative value of anti-HBs <10 mIU/mL, 5 had the quantitative value of anti-HBs between 10 to 100mIU/ mL. A total of 5 serological patterns were detected, and anti-HBe+ /anti-HBc+ pattern was the dominant. There were 262 cases of HBsAg+ /NAT- samples, but only 1 (0.38%, , 1/262) case was HBsAg reactive by CLIA, 100 were anti-HBc reactive (38.17%, 100/262), 144 (54.96%, 144/262) were anti-HBs reactive, and 1 was HBeAg reactive. A total of 8 serological patterns were detected. 【Conclusion】 Most of HBsAg single-ELISA-reactive results are false, and NAT could effectively reduce the residual risk of transfusion transmitted diseases.

Background: Different views have been proposed on the radiofrequency treatment modes and parameters of radiofrequency thermocoagulation of the spinal dorsal root ganglion for the treatment of postherpetic neuralgia (PHN). It is urgent to identify a more effective therapy for patients with PHN. Methods: Patients who underwent radiofrequency thermocoagulation therapy for PHN were retrospectively reviewed and were divided into a radiofrequency thermocoagulation (CRF) and double neddles radiofrequency thermocoagulation (DCRF).The pain scores (numerical rating scale, NRS) were evaluated at the following time points: before the operation, 1 day, 3 months, 6 months, 1 year, and 2 years after operation. The incidence of complications and the degree of pain relief were evaluated. The in vitro ovalbumin experiment was used to indicate the effects of radiofrequency thermocoagulation. Results: Compared with the preoperative NRS scores, the postoperative NRS scores decreased significantly; the NRS scores of the DCRF group was lower than that of the CRF group at all time points from 6 months to 2 years following the operation. The total effective rate of the DCRF group was significantly higher than that of the CRF group at 2 years following the operation. The incidence of numbness in the DCRF group was higher than that noted in the CRF group. The ovalbumin experiments in vitro indicated that the effects of radiofrequency thermocoagulation were optimal when the distance between the two needles was 5 mm. Conclusions DCRF with a 5 mm spacing exhibits a longer duration and higher effective rate in the treatment of PHN and is worth promoting.

OBJECTIVE: To investigate the potential value and its mechanism of dihydroartemisinin (DHA) in the treatment of acute myeloid leukemia (AML). METHODS: The effect of DHA on the viability of AML cells was detected by CCK-8 assay. The effect of DHA on intracellular oxidation-reduction state was detected by fluorescence probe staining and flow cytometry. Western blot, adenovirus transfection, and laser confocal analysis were used to analyze the effect of DHA on autophagy. The small molecule inhibitors were used to further elucidate the possible mechanism of DHA-induced AML cell death. RESULTS: DHA could inhibit the viability of HL-60 and Kasumi-1 cell lines, and significantly increase the level of intracellular oxidative stress. When treated with 10 μmol/L DHA, reactive oxygen species (ROS) in HL-60 cells and Kasumi-1 cells was increased to 2.6 times and 2.0 times, respectively. In addition, the expression of autophagy-related proteins were up-regulated in DHA-treated AML cells, together with the increase of intracellular autophagy flux and activation of autophagy. Furthermore, autophagy inhibitors reduced DHA-induced cell death, and inhibited the level of oxidative stress by scavenging intracellular free radicals, thus inhibiting autophagy and restoring cell viability. CONCLUSION DHA can activate autophagic cell death of AML by inducing oxidative stress.

Renal pelvic hemangioma is a rare benign tumor, presenting with intermittent, total, painless, gross hematuria, accompanied by low back pain, abdominal pain or other symptoms in some cases. Four cases of pyelonephric hemangioma were treated, which were misdiagnosed as malignancy before surgery. For middle-aged patients with intermittent hematuria, if the imaging data cannot rule out renal pelvic hemangioma, it is recommended to perform renoscopy, renal artery angiography or renal puncture biopsy. For patients diagnosed with renal pelvic hemangioma, either partial nephrectomy, ureteroscopic cauterization, or selective renal artery embolization can achieve good results.

【Objective】 To study and analyze the profile of irregular antibodies among voluntary blood donors in Jiaxing area. 【Methods】 The ABO and RhD blood groups of all voluntary blood donors from November 2018 to November 2020 were detected by DIAGAST QWALYS 3 automatic blood group analyzer. According to routine serological screening program of irregular antibody, the samples reactive to O blood cell were sent to the reference laboratory for further identification of the antibody specificity, and the specificity and distribution characteristics of irregular antibodies were analyzed statistically. 【Results】 A total of 79 samples presenting irregular antibodies were yielded out of 90 854 blood samples, with a positive rate of 0.087%. More female samples (n=44) than male (n=35) (P<0.05). 29 donors aged 18 to 31, 33 aged 32 to 45, and 17 aged over 45 years old (P<0.05). 73 samples were RhD positive and 6 were RhD negative (P< 0.05). 40 only donated once, and 39 donated more than twice (P>0.05). 【Conclusion】 Female, RhD negative and more than 45 years old blood donors are more likely to present irregular antibodies, regardless of the number of blood donations.

Objective:To observe the effect of basic fibroblast growth factor (bFGF) treatment on efficacy of adipose-derived mesenchymal stem cells (ADSCs) in cirrhotic rats.Methods:A rat model of liver cirrhosis was established via intraperitoneal injection of carbon tetrachloride (CCl 4) for 10 weeks. Thirty SD rats were randomly divided into 3 groups ( n = 10): control group served as group A, and 0.5ml of phosphate-buffered saline (PBS) was transfused into the tail vein; ADSCs single-dose transplantation group served as group B, and 1×10 6 ADSCs were transplanted into the tail vein; bFGF-treated ADSCs treatment group served as group C, and 1×10 6 bFGF-treated ADSCs were transplanted through tail vein. Liver function, pathological and cytokine changes, and the in vivo survival transformation condition of the transplanted cells were measured at one week after transplantation. F test and an independent sample t test were used. Results:bFGF treatment had significantly promoted the proliferation, differentiation and overexpression of hepatocyte growth factor (HGF) in ADSCs [ADSCs single: (2 137.16 ± 261.52) pg/ml vs. ADSCs (bFGF): (4 776.23 ± 532.44) pg/ml, P < 0.05]. The bFGF-treated ADSCs treatment group had statistically significant differences in promoting the recovery of liver function [alanine aminotransferase (ALT): ADSCs single (190.8 ± 34.98) vs. ADSCs (bFGF): (117.8 ± 35.81) pg/ml; aspartate aminotransferase (AST): ADSCs single (295.2 ± 33.71) U/L vs. ADSCs (bFGF): (183.8 ± 41.29) U/L, P ??< 0.05). There was no statistically significant difference in serum albumin levels between the control group, ADSCs single group, and ADSCs (bFGF) group. Compared with the control group, the serum albumin level of ADSCs (bFGF) group was increased significantly ( P < 0.05), and the difference between the control group and the ADSCs single transplantation group in improving liver regeneration and reducing liver damage was statistically significant ( P < 0.05). Masson trichrome staining showed that the percentage of the liver fibrosis area in the bFGF-treated ADSCs treatment group was 6.78% ± 0.56%, which was significantly higher than that of the control and ADSCs single dose transplantation group (7.96% ± 0.64%) ( P < 0.05). Western blot analysis showed that the expression of HGF protein in the bFGF-treated ADSCs treatment group was significantly up-regulated, while the expression of α-smooth muscle actin was significantly down-regulated, and the difference was significant in the ADSCs single transplantation group. A double fluorescent staining method showed that the numbers of stem cells implanted in the liver tissue of the bFGF-treated ADSCs treatment group were higher than that of the ADSCs single transplantation group. In-vitro cell experiments confirmed that bFGF had significantly promoted the overexpression of HGF in ADSCs. Conclusion:bFGF-treated ADSCs transplantation can significantly improve liver function and fibrosis as compared with ADSCs single-dose transplantation in cirrhotic rats.

Objective: To understand the epidemiological characteristics and differences of HIV-positive cases among 15-24 years old in Jiaxing city and provide evidence for the development of targeted prevention and control measures. Methods: A descriptive epidemiological method was used to analyze the data of HIV cases aged 15-24 reported in Jiaxing from 1999 to 2018. Results: A total of 375 cases of young HIV were reported in 1999-2018, with an average age of 21.29±1.90 years, of which 42 were students. The ratio of male to female was 2.47∶1. The proportion of foreign household registration was higher (76%, 285 cases). The proportion of off-campus youth cases in total cases showed a downward trend(χ2=8.26, P=0.00), but the proportion of student cases showed an upward trend(χ2=15.73, P<0.01). Off-campus youth cases were mainly heterosexual transmission(59.16%, 197 cases), and the students’ cases were mainly homosexual transmission(88.10%, 37 cases). There were significant differences in gender, age, household registration, education level, route of transmission, late detection, CD4 level and source of detection among students and off-campus adolescents(P<0.05). Conclusion The prevalence of AIDS in adolescents and students is worthy of attention. The characteristics of adolescents inside and outside the school are different. Targeted prevention measures should be taken to reduce the harm of AIDS to young people.
