Objective To explore the necessity of opening nephrostomy tube for patients with septic shock follow-ing the indwelling double-J stent of post-percutaneous nephrolithotomy (PCNL),and provide reference for the treatment of septic shock after PCNL.Methods 60 patients with septic shock after PCNL in a hospital from January 1,2015 to December 30,2016 were chosen,patients were randomly divided into clipping nephrostomy tube group (clipping group,n =30) and opening nephrostomy tube group (opening group,n =30),clinical data of two groups of patients were collected and analyzed.Results After 24-hour treatment,heart rate (HR),mean arterial pressure (MAP),oxygen saturation (SpO2),serum lactate (Lac),and hourly urine volume all improved in both groups of patient compared with pre-treatment(all P＜0.05);HR,MAP,SpO2,Lac,and hourly urine volume in opening group after 24-hour treatment were all significantly different from clipping group (all P＜0.05).Levels of serum procalcitonin (PCT) and C-reactive protein (CRP) in two groups after 3-day treatment decreased significantly compared with pre-treatment (both P＜0.05);PCT and CRP levels in opening group after 3-day treatment were both significantly lower than clipping group (both P＜0.05);cure rate of two groups were both 100.00％,hospitalization time and extubation time in opening group were both shorter than clipping group,and cost was less than clipping group,difference were all significant(all P＜0.05).Conclusion Opening nephrostomy tube on the basis of indwelling double-J stent is necessary for patients with septic shock after PCNL.

OBJECTIVESThe staging and treatment of multi-focal non-small cell lung cancer (NSCLC) are controversial. This study evaluated the effectiveness of surgical treatment for the ipsilateral multi-focal NSCLC.

METHODSSixty-eight patients with multi-focal NSCLC underwent complete resection from December 1999 to December 2006. This series included 44 males and 24 females, with a mean age of 60.3 years old (range from 33 to 81 years old). Fifty-four patients had multiple nodules in primary lobe (T4) and 13 patients had additional nodules in non-primary lobe (M1), and a patient was proved to have synchronous primary NSCLC lesions. Surgical treatments included lobectomy in 53 cases, bilobectomy in 4 cases, pneumonectomy in 2 cases, and lobectomy combined with wedge resection in 9 cases.

RESULTSThe median overall survival time of this series was 30 months. Prognostic study demonstrated that mediastinal lymph node metastasis and bronchioloalveolar carcinoma histology had significant impact on overall survival. The median survival times were 39 months for patients with N0 and N1, and 14 months for patients with N2, respectively, and there was significant difference between the groups (P < 0.01). The difference in survival was significant between patients with bronchioloalveolar carcinoma components and other NSCLC histologic types (P < 0.01), and the median survival times were 46 months and 20 months, respectively.

CONCLUSIONSurgery could provide choice for multi-focal NSCLC patients (T4 and M1), especially for patients with bronchioloalveolar carcinoma components and without mediastinal lymph node metastasis.

Objective To quantitatively evaluate the effectiveness of prevention and control measures against pandemic influenza A (H1N1) in Beijing, 2009 and to provide evidence for developing and adjusting strategies for prevention and control of the disease. Methods Considering the seasonality and the number of vaccination on pandemic influenza A (H1N1) , data regarding pandemic influenza A (H1N1) in Beijing were collected and analyzed. Based on the dynamics of infectious disease transmission, a quantitative model for evaluation of prevention and control measures was developed. Results Both latency and infectious periods of pandemic influenza A (H1N1) were estimated to be 1.82 days and 2.08 days, respectively. The effective reproduction numbers of the three periods were 1.13,1.65 and 0.96, respectively. Thanks to the implementation of a series of measures to prevent and control pandemic influenza A (H1N1), the cumulative number of laboratory-confirmed cases of pandemic influenza A (H1N1) was reduced, making it much smaller than what would have been under the natural situation. Specifically, the program on pandemic (H1N1) 2009 vaccination reduced the cumulative number of laboratory-confirmed cases by 24.08% and postponed the peak time. Conclusion Measures that had been taken during this period, had greatly contributed to the successful prevention and control of pandemic influenza A (H1N1). The 2009 Pandemic (H1N1)vaccination was confirmed to have contributed to the decrease of cumulative number of laboratoryconfirmed cases and postponed the peak arrival time.

OBJECTIVEThe staging and treatment of bronchioloalveolar carcinoma (BAC) with pulmonary metastasis are still controversial. This study aimed at evaluating the current staging of BAC with ipsilateral intrapulmonary metastatic nodules and the therapeutic effectiveness of surgical resection.

METHODSThe clinicopathological data of 729 completely and surgically resected patients with non-small cell lung cancer (NSCLC) from December 1999 to December 2006 were retrospectively reviewed. Prognostic factors affecting the overall survival were analyzed by the Kaplan-Meier method and compared by the log rank test.

RESULTSAmong 67 NSCLC patients with ipsilateral intrapulmonary metastatic nodules, 54 had multiple nodules in the lobe with primary lesion (T4, PM1) and 13 had additional nodules in the other ipsilateral lobes (M1, PM2). This series consisted of 40 males and 27 females, with a median age of 60.0 years. Of those, 28 had the lesions containing pure or some bronchioloalveolar carcinoma component, while the other 39 had a NSCLC lesions containing non-bronchioloalveolar carcinoma components. The median overall survival time of this series was 24.0 months. Prognostic study demonstrated that bronchioloalveolar carcinoma histology and mediastinal lymph node metastasis had significant adverse impact on the overall survival. The median survival time of the patients with bronchioloalveolar carcinoma was 58.0 months versus 27.0 months in patients with other subtypes of NSCLC (P < 0.01). The median survival times were 39.0 months for the patients with N0 or N1 versus 14.0 months for patients with N2, with a significant difference between the two groups (P < 0.01). There was no significant difference in the survival time between the patients with PM1 (36 months) and those with PM2 (24 months) (P > 0.05).

CONCLUSIONSurgical resection is effective for NSCLC patients with ipsilateral intra-pulmonary metastasis, especially for those with bronchioloalveolar carcinoma components. Our results suggest that the current TNM classification system may be inappropriate for the NSCLC patients with ipsilateral intrapulmonary metastatic nodules, and may need a modification.

Taking the Chinese city of Xiamen as an example, simulation and quantitative analysis were performed on the transmissions of the Coronavirus Disease 2019 (COVID-19) and the influence of intervention combinations to assist policymakers in the preparation of targeted response measures. A machine learning model was built to estimate the effectiveness of interventions and simulate transmission in different scenarios. The comparison was conducted between simulated and real cases in Xiamen. A web interface with adjustable parameters, including choice of intervention measures, intervention weights, vaccination, and viral variants, was designed for users to run the simulation. The total case number was set as the outcome. The cumulative number was 4,614,641 without restrictions and 78 under the strictest intervention set. Simulation with the parameters closest to the real situation of the Xiamen outbreak was performed to verify the accuracy and reliability of the model. The simulation model generated a duration of 52 days before the daily cases dropped to zero and the final cumulative case number of 200, which were 25 more days and 36 fewer cases than the real situation, respectively. Targeted interventions could benefit the prevention and control of COVID-19 outbreak while safeguarding public health and mitigating impacts on people's livelihood.
