ObjectiveTo analyze the epidemiological characteristics of influenza virus in severe acute respiratory tract infection (SARI) cases in Jingzhou City, so as to provide a scientific basis for the formulation of influenza prevention and control policies in Jingzhou City. MethodsSARI surveillance was carried out in two sentinel hospitals in Jingzhou City from 2018 to 2023. Respiratory tract samples were collected from cases and influenza virus nucleic acid was measured using real-time fluorescent polymerase chain reaction (RT-PCR). ResultsA total of 2 603 SARI samples were tested from 2018 to 2023, and 338 samples were positive for influenza virus nucleic acid, with a detection rate of 12.99%. The highest positive detection rate was 20.22% in 2019, followed by 14.29% in 2022, and the lowest detection rate was 7.75% in 2020. There were significant differences for the positive detection rates of influenza in each monitoring year (χ²=30.386, P<0.001). There were epidemic peaks in the five surveillance years from 2018 to 2023 except 2020. There were winter epidemic peaks during 2018‒2019 and 2021‒2022, and an obvious summer epidemic peak was also observed from 2019 to 2022. H1N1, H3N2, B-Victoria and B-Yamagata were alternately prevalent in the six surveillance years. In 2019, H1N1, H3N2 and B-Victoria were alternately prevalent with time progress, in 2021 only B-Victoria was prevalent, and in 2022 H3N2 and B-Victoria were prevalent. There was no statistically significant difference for the positive detection rates of influenza virus between different genders (χ²=0.178, P=0.673). Among the four age groups, the positive rate of influenza virus in the age group of 15‒<25 years old was the highest (40.91%), followed by the age group of 25‒<60 years old (21.31%). There were statistically significant differences for the positive rates of influenza virus among different age groups (χ²=24.496, P<0.001). ConclusionThe surveillance of SARI cases in Jingzhou City could serve as an effective supplement to the surveillance of ILI in sentinel hospitals. It is suggested to expand the surveillance scope, strengthen public education and outreach on the prevention and control of respiratory diseases, thereby providing a scientific basis for influenza prevention and control.

Objective To compare the value of stack-of-stars-volumetric interpolated breath-hold examination(Star-VIBE)and T1-volumetric interpolated breath-hold examination(T1-VIBE)MRI for displaying peripheral lung cancer.Methods Fifty-two patients with 56 peripheral lung cancer were prospectively enrolled,and chest Star-VIBE and T1-VIBE MRI were acquired.The morphological features were observed,and the subjective scores were recorded.The maximum diameter,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of lesions were measured based on Star-VIBE and T1-VIBE MRI,respectively.Taken CT as the references,the value of Star-VIBE and T1-VIBE MRI for displaying peripheral lung cancer were compared.Results Star-VIBE MRI had higher scores for displaying spiculation sign,lobulation sign,pleural depression sign and halo sign than T1-VIBE(both P＜0.05).CNR and SNR of Star-VIBE MRI were significantly higher than those of T1-VIBE(both P＜0.001).No significant difference of the maximum diameter of lesions measured based on Star-VIBE and T1-VIBE MRI compared with CT was found,nor between Star-VIBE and T1-VIBE MRI(all P＞0.05).Conclusion Star-VIBE MRI had better value for displaying peripheral lung cancer than T1-VIBE.

To investigate the efficacy and safety of modified endoscopic retrograde appendicitis therapy (ERAT) in children with acute uncomplicated appendicitis complicated with intussusception. Data of 6 patients with acute uncomplicated appendicitis complicated with intussusception who received modified ERAT were collected from October 2018 to February 2020 in Pediatrics Department of Tangdu Hospital. The reduction rate of intussusception, the success rate of ERAT appendiceal intubation and endoscopic treatment, the remission time of clinical symptoms, the time of white blood cells return to normal, the length of hospital stay, complications and recurrence were summarized. All the 6 patients were confirmed to be acute uncomplicated appendicitis combined with ileocecal intussusceptions under colonoscopy. Endoscopic intussusception reduction and ERAT were performed successfully. The mean time of disappearance of abdominal tenderness was 1.3 days after the therapy, and the time of white blood cells return to normal was 1 day after surgery. The endoscopic treatment were all successful and the length of hospital stay was 3-6 days. No complications or recurrence of intussusception and appendicitis occurred during the follow-up period of 6-12 months. Modified ERAT can effectively, safely and minimally invitingly treat acute uncomplicated appendicitis with intussusception in children on the basis of definite diagnosis.

ObjectiveTo explore the application law of compound prescriptions containing Coptidis Rhizoma to diabetes and its complications based on data mining. MethodA total of 288 records on formulas containing Coptidis Rhizoma in the treatment of diabetes and its complications and the corresponding syndromes and symptoms were retrieved from the medical records of modern physicians， with 218 on the treatment of diabetes and 70 on the treatment of diabetes complications. The Traditional Chinese Medicine Inheritance Computing Platform （V3.0） was used or data mining on the compositions of the formulas. Moreover， it was employed for the frequency statistics， formula analysis， symptom analysis， association rules analysis， network visualization， and cluster analysis. ResultThe 218 formulas containing Coptidis Rhizoma for the treatment of diabetes involved 190 Chinese medicinals. A total of 12 syndromes showed the occurrence frequency ≥ 6， and the one with the highest frequency was deficiency of both qi and yin， followed by the syndrome of excessive heat in lung and stomach， syndrome of Yin deficiency and effulgent fire， and syndrome of excessive heat and fluid consumption. The dose of Coptidis Rhizoma for the treatment of diabetes ranged from 1.5-30 g， and the most frequently used doses were 10， 6， and 5 g. The medicinal was frequently applied for the traditional Chinese medicine symptoms of dry stool， dry mouth and tongue， and swift digestion with rapid hungering. Moreover， 26 core medicinal pairs， 17 association rules， 3 diagrams on medicinal relationship， and 3 core combinations were yielded. The 70 formulas containing Coptidis Rhizoma for the treatment of diabetes complications involved 184 Chinese medicinals， and the top 3 complications were diabetic nephropathy， diabetic peripheral neuropathy， and diabetic gastroenteropathy. The dose of Coptidis Rhizoma in the treatment of diabetes complications fell in the range of 2-15 g， and 10， 6， and 5 g were most frequently used. ConclusionFormulas containing Coptidis Rhizoma for the treatment of diabetes and its complications mainly target the syndrome of dampness-heat transforming into fire and the syndrome of excessive heat damaging yin.

AIM: To compare the early response to the new and traditional antiepileptic drugs (AEDs) in the treatment of partial epilepsy. METHODS: Patients from neurology Department of Huzhou Central Hospital between January 2013 and June 2018 were included; outcomes included time to first seizure, time to treatment failure and 6-month, 1- and 2-year seizure-free rates were compared. RESULTS: A total of 250 patients with partial epilepsy were divided into carbamazepine (CBZ) group (n =62), levetiracetam (LEV) group (n = 67), oxcarbazepine (OXC) group (n = 63), and lamotrigine (LTG) group (n = 58). In terms of time to first seizure after monotherapy, CBZ and OXC were equivalent (P = 0.635), while CBZ was superi- or to LTG (P < 0.001) and LEV (P = 0.005); regarding time to treatment failure, CBZ and LTG had the same response (P = 0.721), while CBZ was superior to OXC and LEV (P = 0.008 and P = 0.018, respectively). For the "6-month seizure-free" rate, differences were not statistically significant. For the " 1 - and 2-year seizure-free" rates, CBZ > LTG > OXC > LEV, and CBZ was superior to OXC and LEV (all P < 0.05), but not LTG (P > 0.05). A total of 25 patients had adverse reactions; with CBZ (19.3%) more often than LTG (8.6%), OXC (7.9%), or LEV (4.5%). CONCLUSION: Treatment response to CBZ is superior compared to that of OXC and LEV, especially in the early stages of treatment, and equivalent to that of LTG, but the incidence of side effects is higher as well.

To explore the role of P2X4 receptor in opioid-induced hyperalgesia (OIH).
 Methods: A total of 30 Sprague-Dawley (SD) male rats were randomly divided into 5 groups: a saline (N0) group, a remifentanil at 0.5 μg/(kg.min) (R1) group, a remifentanil at 1.0 μg/(kg.min) (R2) group, a remifentanil at 1.5 μg/(kg.min) (R3) group, and a remifentanil at 5.0 μg/(kg.min) (R4) group. The paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were measured at follow time points to optimize the dosages: the day before treatment (T1), 30 min after tail intravenous catheterization (T2), and 30 min (T3), 1 h (T4), 2 h (T5), 24 h (T6) after withdrawal from remifentanil. Then, the rats were randomly divided into 2 groups: a saline group (N group), a remifentanil at 1.0 μg/(kg.min) group (R group). The PWMT and PWTL were measured at follow time points: T1, T2, and T4. The lumbar enlargement of spine was selected at 1 h after withdrawal from remifentanil, and the expression of P2X4 receptor mRNA and protein was examined in OIH. Additional male rats were selected and randomly divided into 2 groups: a plantar incision surgery followed by saline treatment group (I+N group), a plantar incision surgery followed by remifentanil treatment group (I+R group). The PWMT and PWTL were measured at follow time points: T1, T2, T3, T4, T5, T6, 48 h (T7) and 72 h (T8) after withdrawal from remifentanil. The lumbar enlargement of spine was selected at 1 h after withdrawal from remifentanil, the expression of P2X4 receptor mRNA and protein was examined by PCR and Western blotting, and the microglial activation in spine 1 h after withdrawal from remifentanil were assessed by immunofluorescence.
 Results: The pain thresholds including PWMT and PWTL in different groups were as follows: R4 group Animals ; Hyperalgesia ; Male ; Pain, Postoperative ; Rats ; Rats, Sprague-Dawley ; Receptors, Purinergic P2X4 ; Remifentanil ; Spinal Cord

Objective To study the changes of cytokines in aqueous humor of patients with proliferative diabetic retinopathy (PDR)after intravitreal bevacizumab (IVB) and the correlation of these cytokines.Methods Fifty-six patients(63 eyes) with severe PDR underwent pars piana vitrectomy (PPV) with IVB pretreatment in our hospital from April,2014 to February,2015 were collected.All the patients received IVB therapy from 3 days to 7 days before PPV.Aqueous humor samples were collected at the time of IVB and PPV treatment.The concentrations of vascular endothelial growth factor (VEGF),interleukin-6 (IL-6),interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) were measured by cytoinetric bead array (CBA).The changes of these cyto-kines after IVB were analyzed by using Wilcoxon rank sum test for paired data.The correlation between these cytokines was analyzed by using Spearman rank test.Results From 3 days to 7 days after IVB,the concentration of VEGF in aqueous humor was (6.57 ± 12.29)pg · mL-1,lower than the pre-operation of (278.71 ±340.20)pg · mL-1,the difference was statistically significant (P ＜ 0.05).The concentration of IL-8 was (385.60 ± 1099.47) pg · mL-1,higher than pre-operation of(298.87 ± 1005.79) pg ·mL-1,the difference was statistically significant (P ＜ 0.05).IL-6 and MCP-1 were increased after IVB,but the difference was not statistically significant (all P ＞ 0.05).VEGF,IL-6,IL-8 and MCP-1 had an obviously relationship between each two factors(all P ＜ 0.05).Conclusion Angiogenesis in patients with PDR are regulated by a variety of cytokines,and targeted reduction of VEGF may compensatory increase the concentration of other inflammatory cytokines.

Objective To evaluate the predictive role of TEL/AML1 fusion gene in protocol CCLG-ALL-2008 and to identify relevant factors influencing the outcome of ALL with TEL/AML1 fusion gene. Methods Ninety-nine patients with ALL harboring TEL/AML1 fusion gene (positive) and 329 cases without any specific fusion genes (negative) at diagnosis of B-lineage ALL from June 2008 to December 2014 were enrolled and their clinical and biological features were analyzed. Following-up ended in October 2015, the survival status was calculated by K-M curve and prognostic factors were analyzed by COX model. Results There were no differences between the two groups in age, white blood cell at the diagnostic stage, and treatment responses at 4 time points, namely, prednisone good response on day 8, M3 status of BM on D15, and the minimal residual disease (MRD) more than 1.0×10-3 on day 33 and 12th week. During the follow-up period, the relapse rate was lower in the positive group than that in the negative group (14/99 vs 69/329), the mortality rate of the negative group was twice of that in the positive group (55/329 vs 8/99). The five-year overall survival (OS) rate, relapse-free survival (RFS) rate and event-free survival (EFS) rate of the positive group were (86.1 ± 4.9)%, (80.7 ± 5.1)% and (78.9 ± 5.1)%, respectively, and (79 ±2.8)%, (72± 3.1)%, and (69.6+ 3.1)% for the negative group as well. COX regression analysis indicated that relapse and MRD level at the 12th week were independent prognostic factors on OS, RFS, and EFS (P<0.05) for the two groups. Conclusions TEL/AML1 fusion gene could be regarded as a relatively good indicator of risks in ALL children treated by CCLG-ALL-2008 protocol. ALL patients with TEL/AML1 are recommended to receive more intensive therapy including hematopoietic stem cell transplantation when the patients were high level of MRD on the 12th week after treatment.

Objective To observe the efficacy and effect on cerebral vascular reserve and serum hs-CRP of Xueshuantong combined with butylphthalide in patients with acute cerebral infarction.Methods A total of 140 cases with ACI in Huzhou Central Hospital from August 2015 to July 2016 were divided into the observation group and the control group with 70 cases in each group, according to the order of single and double number.The control group was treated with routine western medicine while giving butylphthalide , and the observation group was given Xueshuantong on the basis of the control group.After two weeks of treatment, the efficacy and CVR, BHI and hs-CRP levels were observed.Results After treatment, the total effective rate of the observation group was 92.86%, and the control group was 81.43%, the difference was statistically significant (χ2 =4.080, P<0.05), there was significant differences of CVR, BHI between two groups (Fgroup =5.534, 4.608, P<0.05), the CVR and BHI increased gradually with time (Ftime =11.325, 9.432, P<0.05), the rised amplitude in observation group was higher than the control group (Finteraction =5.742, 5.016, P<0.05), there were significant differences in the levels of hs-CRP between two groups (Fgroup =7.421, P<0.05), and hs-CRP decreased gradually with time (Ftime =10.185, P<0.05), the decrease of observation group was larger than that of control group(Finteraction =4.824, P<0.05).Conclusion Xueshitong combined with butylphthalide in the treatment of ACI is effective , can better improve cerebral vascular reserve capacity and inhibition of inflammatory response, better than the single use of butylphthalide.
