Objective: To analyze the epidemic trend of viral hepatitis in Nanjing from 1989 to 2019 and predict the incidence in 2020, so as to provide reference for the prevention and control of viral hepatitis. Methods: The incidence data of viral hepatitis in Nanjing from 1989 to 2019 was retrieved from Nanjng Center for Disease Control and Prevention and National Infectious Disease Reporting System. The epidemic trend was analyzed by estimating the annual percent change ( APC ) and the average annual percent change ( AAPC ). The seasonal incidence of different types of viral hepatitis was analyzed by seasonal index. The autoregressive integrated moving average model ( ARIMA ) was built to predict monthly incidence rate of viral hepatitis in 2020. Results: The annual incidence rate of viral hepatitis was 62.00/100 000 in Nanjing from 1989 to 2019, showing a downward trend ( AAPC=8.4%, P<0.05 ). From 1998 to 2019, the annual incidence rates of hepatitis A, B, C and E were 1.98/100 000, 14.31/100 000, 2.30/100 000 and 2.60/100 000. The incidence of hepatitis A and B showed downward trends ( AAPC=-11.81%, -6.02%, both P<0.05 ); the incidence trend of hepatitis C was not obvious ( P>0.05 ); the incidence of hepatitis E showed an increasing trend ( AAPC=4.82%, P<0.05 ). From 2015 to 2019, the third and fourth quarters were the epidemic seasons of hepatitis A, B and C, while the first and second quarters were the epidemic seasons of hepatitis E. The ARIMA model predicted that the monthly incidence rates of viral hepatitis in 2020 would range from 1.26/100 000 to 3.69/100 000, among which hepatitis B ranged from 1.21/100 000 to 2.58/100 000, hepatitis C from 0.20/100 000 to 0.48/100 000, hepatitis E from 0.09/100 000 to 0.25/100 000. Conclusions The incidence of viral hepatitis in Nanjing shows a downward trend. Among different types of hepatitis, hepatitis B has a higher incidence. All types of hepatitis have epidemic seasons. It is predicted that the monthly incidence rates of viral hepatitis will be 1.26/100 000 to 3.69/100 000 in 2020.

ObjectiveTo explore the influence of 3C bolus wizard on postprandial glucose levels in diabetic patients. MethodFifty-eight patients with type 2 diabetes in our hospital were monitored with continuous glucose monitoring system(CGMS), continuous subcutaneous insulin infusion(CSII)and CareLink(3C for short)for 6 days.The function of “3C” bolus wizard was applied during treatment and all the patients were given dietary nursing and health education.The glucose level was observed.ResultThe level of P2hBG of the 58 patients was between 6.4~10.7mmol/L in 3~6 days.ConclusionsBolus wizard plays an important role in “3C” treatment.It can make the postprandial glucose of patients satisfactorily controlled in a short time only to avoid insulin hypoglycemia because of large doses of insulin.At the same time,health education on patients can achieve remarkable results as well.

Objective To evaluate the effect of propofol on noise-induced hearing loss in guinea pigs.Methods Forty-eight healthy adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 4 groups (n =12 each) using a random number table:control grotup (C group),propofol group (P group),noise-induced hearing loss group (N group),and propofol + noise-induced hearing loss group (P + N group).A loading dose of propofol 5 mg/kg was infused intravenously over 5 min,followed by infusion at 20 mg· kg-1 · h-1 for 115 min in P and P + N groups,while the equal volume of normal saline was given in N group.N and P+ N groups were exposed to the noise of 4 kHz center frequency and 118-122 dB sound pressure level for 120 min.Distortion product otoacoustic emission (DPOAE) was measured before noise exposure (T1) and at 1 h after the end of noise exposure (T2) and the amplitudes were recorded at the frequencies of 2,4,6 and 8 kHz.After the second measurement of DPOAE,all the animals were sacrificed and organs of Corti were harvested for determination of cochlear 8-isoprostaglandin F(2alpha) (8-iso-PGF2α) content (by ELISA assay) and out hair cell (OHC) count.The rate of OHC lesions was calculated.Results The DPOAE amplitude was significantly lower at frequencies of 4,6 and 8 kHz at T2 than at T1 in N and P + N groups (P ＜ 0.05).Compared with C group,the DPOAE amplitude was significantly decreased at frequencies of 4,6 and 8 kHz at T2,while the cochlear 8-isoPGF2α content and rate of OHC lesions were increased in N and P + N groups (P ＜ 0.05).Compared with N group,the DPOAE amplitude was significantly increased at frequencies of 4,6 and 8 kHz at T2,while the cochlear 8-iso-PGF2α content and rate of OHC lesion were decreased in P + N group (P ＜ 0.05).Conclusion Propofol can reduce noise-induced hearing loss in guinea pigs possibility through decreasing oxidative stress response-induced damage to cochlear OHCs.

Objective To study common Gram negative bacterial pathogens and their drug resistant pattern in sputum isolates from patients in pediatric intensive care unit (PICU) of Chengdu children' s hospital. Methods Comparing to the period of 2004-2006 with 2007-2009, we retrospectively reviewed eligible sputum isolates of common Gram negative bacilli and their drug resistance pattern. All specimens were processed according to standard microbiological methods for both quantitative and qualitative cultures. Pathogen was the single predominant growth after two consecutive cultures. Strict quality control was used in all test agents and paper disk for drug resistance analysis. Results Total of 598 Gram negative bacterial isolates were identified in patients over 6 years. The first 5 bacteria respectively were Escherichia coli 167 samples(27.93%), Klebsiella pneumoniae 109 samples ( 18.23% ), Enterobacter cloacae 93 samples ( 15.55% ),Acinetobacter baumannii 64 samples ( 10. 7% ), Pseudomonas aeroginosa 43 samples (7. 19% ). They were mostly sensitive to Imipenam, Amikacin, Piperacillin/Tazobactam. Most drug resistance rate was found in Amoxicillin, Ampicillin, Cephalosporin. Apart from Pseudomonas aeroginosa and Acinetobacter Baumannii,no Gram negative bacteria was found to be resistant to Imipenam. Klebsiella pneumoniae and ESBL secreting Escherichia coli isolates were obviously increasing when compared to 3 years ago. Conclusion Comparing the period of 2004-2006, the Gram negative bacterial isolates were increasing in our PICU patients during 2007 to 2009. Close monitoring of drug resistance pattern changes in PICU would guide rational use of antibiotics in these critically ill children.

Objective To determine the clinical efficacy of the combination of Aidi injection and chemotherapy in patients of advanced non-small-cell lung cancer (NSCLC). Methods One hundred and twenty three patients with stage ⅢB/Ⅳ NSCLC complying with diagnosis standard were eligible.Those patients were randomly divided into treatment group (63 patients) and control group (60 patients). Both of groups received NP regimens( NVB 25 mg/m2, ivgtt, d1,d8; DDP 25 mg/m2, ivgtt, d1-3, watering). In treatment group,patients received Aidi injection (50 ml, ivgtt, d1-10) combined with NP regimens. Then some indexes were observed, including outcomes in the overall response rates, adverse drug reaction, quality of life. Results In treatment group, outcomes in the overall response rates were 50.8 %, 5 patients were completely remitted(CR),27 patients were partly remitted(PR). In control group, outcomes in the overall response rates were 35.0 %(3 CR, 18 PR). Gastrointestinal reaction and bone marrow depression of treatment group was lower than control group. Quality of life of treatment group was higher than control group. The difference was significant between two groups (P＜0.05). Conclusion This Aidi injection plus chemotherapy combination is effective against NSCLC with mild toxicities and quality of life can be improved.

In recent years, the targeted protein degradation technology has developed quickly, with proteolysis-targeting chimera (PROTAC) as the best-known strategy through exploring the ubiquitin-proteasome system. A number of new targeted protein degradation strategies have been emerging to expand the scope of protein degradation technology, including lysosome-targeting chimeras (LYTACs), autophagy-targeting chimeras (AUTACs), autophagosome-tethering compounds (ATTECs) and chimeras based on chaperone-mediated autophagy (CMA). The emerging methodologies have explored another important protein degradation system in eukaryotes-lysosomal systems, such as the endosome-lysosome pathway and the autophagy-lysosome pathway. This review summaries the mechanisms and features of different strategies for targeted protein degradation, with a special emphasis on the new targeted protein degradation technologies, such as their current status, advantages and limitations.

OBJECTIVETo confirm diagnosis of a special case with chief complaints of abdominal pain and dyskinesia of lower extremities.

METHODSThe clinical symptoms, signs, MRI, pathological findings and the results of blood test for microfilaria were analyzed.

RESULTSThe patient was a 6-year old girl who had abdominal pain for 10 days dyskinesia of lower extremities for 6 days accompanied by difficulty in urination and defecation. There was tenderness on T7-9 spinous process, sensory dullness below the umbilicus. Babinski's and Oppenheim's sign were bilaterally positive, and ankle clonus was positive. MRI showed space occupying change in the vertebral canal at T7-9 level. The mass of 2 cm x 1 cm x 1 cm size was removed by surgical operation and histopathological study showed obvious fibrous tissue proliferation accompanied by eosinophil, lymphocyte and neutrophil infiltration around a worm-like structure. Night time blood test performed at 23:00 confirmed the presence of microfilaria.
