Oral feeding of water cannot be accomplished in some critical patients due to coma, mouth-breathing or long-term indwelling of gastric tube, causing dry mouth which results in oral pain, ulcer, or infection, aggravating patients' discomfort and even affecting the prognosis. To solve this problem, the medical staff of the First Hospital of Jiaxing developed a novel oral humidifier and obtained the National Utility Model Patent of China (ZL 2019 2 0066979.0). The oral humidifier consists of a spraying device and a fixation device. The spraying device is a spraying housing with a water tank, and a spraying port where nanometer water mist can be emitted. The spraying housing is also equipped with a flashlight with a switch, and a schematic diagram of pupil size, which can be used to assess the pupil size conveniently. The fixing device is composed of a fixing frame, an adjustable rod and a clamp. The two ends of the adjustable rod are connected to the fixing frame and the clamp respectively, and can be adjusted to proper shape. The spraying housing can be placed on the fixing frame and installed on the bed and adjusted to the proper position quickly. This novel oral humidifier is a simple device which combines a spraying system with a pupil evaluation tool, implying significant clinical application in improving the convenience of nursing and alleviating dry mouth of critical patients.

OBJECTIVE To study the degree and regular of Aspergillus flavus air contamination in hospital.METHODS Some ambient air of different environment in our hospital was taken 5 times in one day of four seasons one year by using centrifugal air sampler,and then cultivated(using eumycete cultural methods),counted and analyzed.RESULTS A.flavus strain was collected in all sampling points in four seasons.The concentration of Aspergillus flavus in six standort was diverse from each other,and the highest was the out-patient clinic with 1238.9 CFU/m3.The concentration of Aspergillus flavus in each division of Medical Department was significant difference during four seasons(P0.05).The difference between internal medicine and external enviroment was significant between the first and the third season(P=0.022,P=0.039),but that of the second and the fouth season was not significant(P=0.022,P=0.624).CONCLUSIONS The contamination of Aspergillus flavus in hospital was severe.So it′s necessary to prevent the Aspergillus flavus infection and enhance the environmental control of susceptible population.

This paper studies the vein extraction technique based on the susceptibility weighted imaging (SWI) and introduced an improved self-adaptive threshold method based on the vessel enhancing diffusion. The approach employs the combination indicator of the local gray character, the global gray character and the tubular information of the vein. It first applies the vessel enhancing diffusion filter to enhance the continuity of the vein, increases the detection rate of tiny vein and suppresses the nucleus areas. And then it uses the improved self-adaptive threshold method to extract the vein. The results demonstrate that this approach can solve the problem above and extract the vein from the SWI image accurately.

Objective: To analyze the clinical features of inpatients infected with influenza A virus, and then to provide evidence for the diagnosis, treatment and prevention of influenza A in primary hospital. Methods: The clinical data of inpatients with influenza A in one district hospital from Dec 2016 to Mar 2017 were collected to analyze retrospectively. Results: A total of 21 665 patients were admitted to hospital from Dec 2016 to Mar 2017. Among them 647 flu-like cases accepted influenza A nucleic acid detection, and 203 cases were positive, the positive rate was 31.4%. The median age of influenza A positive patients was 64.25 years, and 20.2% were 0 to 4 years, 49.26% were 65 years of age or older. 58.13% patients had at least one underlying medical condition. Fever, Cough and Sputum were the most symptoms of patients infected with influenza A. Compared with the patients under 60 years old, non-fever symptoms were more common in those 60 years or older, the difference was statistically significant (χ²=15.43, P<0.001). Laboratory examination indicated that lymphocytopenia were detected in 54.27% of patients, and increased level of C-reactive protein and procalcitonin (PCT) in 74.83% and 11.76% of patients respectively. Moreover, 75.58% of patients had high erythrocyte sedimentation rate (ESR), 8 patients (97.3%) had findings consistent with pneumonia. 78.33% of patients received anti-viral treatment with oseltamivir, the rate of antibiotic utilization was as high as 85.22%. The median of hospitalization expense of patients infected with influenza A was 4 280 (interquartile range 2 792-9 565) yuan, and the cost of inpatients who had combined underlying diseases were higher than that in inpatients who had no coexisting medical conditions, the difference was statistically significant (Z=7.106, P<0.01). No death occurred in this study. Conclusions Children and old people were at high risk for influenza A infection. Fever, cough and lymphocytopenia were the common clinical features of patients infected with influenza A. It is especially noteworthy for the patients who were 60 years of age or older with flu-like symptoms but without fever, or the patients who had one or more underlying medical conditions, and such patients should receive influenza virus nucleic acid tests as early as possible.

In daily medical work, most of the critically ill patients who cannot move by themselves are pulled and lifted by manpower, often relying on the cooperation of many doctors and nurses, which not only increases the risk of transfer and patients' discomfort, but also causes certain skeletal and muscle damage to the porters. The emergency department of the First Hospital of Jiaxing City, Zhejiang Province designed a kind of patient transfer device, and obtained the National Utility Model Patent (ZL 2018 2 0579844.X). The transfer device is composed of upper frame, lower frame and base. The upper frame and the lower frame are rectangular and in a horizontal position. The upper frame can slide laterally through the circular tubes which are fixed on the lower frame. The lower part of the base is provided with four universal foot brake wheels. During the usage, the booster frame facilitates the transfer of patients by the rolling and two sliding tracks of the circular tube, which can make patients move smoothly and comfortably, and reduce the working intensity of the transporter. This device has good practical value.

Objective:To explore the efficacy and prognostic factors of intensity-modulated radiotherapy (IMRT) in elderly patients with locally advanced esophageal cancer.Methods:The clinical data of 87 elderly patients with locally advanced esophageal cancer who received IMRT and 79 elderly patients with locally advanced esophageal cancer who received three-dimensional conformal radiotherapy (3DCRT) from January 2005 to December 2015 in Changzhou Cancer Hospital Affiliated to Soochow University were retrospectively analyzed, and their efficacy and adverse reactions were observed. The log-rank test and Cox proportional hazards model were used for univariate and multivariate analyses to analyze the prognostic factors of patients receiving IMRT.Results:In the IMRT group, 27 cases (31.0%) achieved complete remission, and 60 cases (69.0%) achieved partial remission; in the 3DCRT group, 18 cases (22.8%) achieved complete remission, and 61 cases (77.2%) achieved partial remission. There was no statistical difference in the short-term efficacy (CR+PR) between the two groups ( χ2 = 1.43, P = 0.232). The 1-, 3-, and 5-year overall survival rates in the IMRT group were 77.0%, 46.0% and 23.0%, respectively, and the 3DCRT group were 70.1%, 40.5% and 10.1%, respectively. There was a statistical difference in the overall survival between the two groups ( χ2 = 4.89, P = 0.027). For elderly patients with locally advanced esophageal cancer who received IMRT, univariate analysis showed that gender, lesion location, T stage, gross tumor volume, and short-term efficacy were prognostic factors (all P < 0.05); multivariate analysis showed that lesion location, T stage, gross tumor volume, and short-term efficacy were independent prognostic factors (all P < 0.05). In the IMRT group, the incidence rate of ≥ grade 2 radiation pneumonitis was 10.3% (9/87), the incidence rate of ≥ grade 2 radiation esophagitis was 32.2% (28/87), the incidence rate of leukopenia was 18.4% (16/87), and the incidence rate of hemoglobin reduction was 7.0% (6/87), and there was no statistical difference in the incidence of acute adverse reactions between the IMRT group and the 3DCRT group (all P > 0.05). Conclusions:IMRT has more advantages than 3DCRT in the treatment of elderly patients with locally advanced esophageal cancer, especially those with upper cervical and thoracic lesion, T 1-3 stage, gross tumor volume ≤40 cm 3, and complete remission in a short term can benefit from it, and the adverse reactions are mild.

Objective To evaluate the clinical outcomes and feasibility of multi-modality adjuvant chemotherapy and radiation, which was conducted as postoperative chemotherapy, radiation, and consolidation chemotherapy (CRC) mode for the treatment of advanced endometrial cancer. Methods A retrospective analysis of 124 patients with International Federation of Gynecology and Obstetrics (FIGO) stages Ⅲ and Ⅳ endometrial cancer from Jan. 2004 to Oct. 2012 was conducted in Peking University People′s Hospital and Beijing Obstetrics and Gynecology Hospital. Inclusion criteria were comprehensive staging procedure including hysterectomy, bilateral salpingo-oophorectomy, and (or) selective pelvic aortic lymphadenectomy, and treatment with adjuvant chemotherapy and (or) radiation. The average age of these patients was (55.9 ± 8.4) years old (range from 23 to 79 years old). According to different postoperative adjuvant treatment modes, the patients were divided into CRC group, chemotherapy-radiotherapy (CR) group and single chemotherapy (C) group. The survival and side effects of the three groups were compared. Results (1) One hundred and twenty-four patients with advanced stage endometrial cancer were identified and received postoperative adjuvant therapies.Sixty-one (49.2％, 61/124) cases of them received postoperative CRC fashion, 19 (15.3％, 19/124) received postoperative CR and 44 (35.5％, 44/124) cases received C. The age, stage, grade and type of surgery of the three groups were not significantly different (all P>0.05);while, the pathology, chemotherapy cycles and chemotherapy regimens differed significantly (all P<0.05). (2) The progression-free survivals (PFS) of the patients with CRC, CR, and C group were (121±7), (68± 15), and (100±11) months, respectively. The 3-year PFS rates were 87.9％, 43.7％, and 61.4％, respectively. The 5-year PFS rates were 82.2％, 36.4％, and 61.4％, respectively. The above indicators were significantly higher in the CRC group than in the CR group (all P<0.01), and there was no difference between the CRC group and the C group (P=0.037). The overall survival (OS) of patients with CRC, CR, and C group were (128 ± 6), (80 ± 12), and (99 ± 10) months, respectively. The 3-year OS rates were 87.8％, 72.4％, and 67.1％, the 5-year OS rate were 84.2％, 54.3％, and 64.1％, respectively. The above indicators were significantly higher in the CRC group than those in the CR group and C group (all P<0.01). (3) There was no difference in the frequency of adverse effects either chemotherapy, such as severe bone suppression or radiotherapy;hepatotoxicity,blood transfusion, dose modifications;or cycle delays between the CRC, CR and C group (all P>0.05). (4) In the univariate analysis shown that, stage, the fashion of postoperative adjuvant therapy and type of surgery were risk factors for tumor progression in patients with advanced endometrial cancer (P<0.05). After adjusted for FIGO stage and type of surgery, the tumor progression hazard ratio (HR) was 3.931 (95％CI:1.734-8.914, P=0.001) for the CR group and 2.188 (95％CI:1.010-4.741, P=0.047) for the C group, compared to the CRC group. Conclusion Sequential CRC delivered in a"sandwich"fashion for the treatment in advanced endometrial cancer could significantly improve the 3-year and 5-year OS rates and have a similar adverse effect profile compared with other sequencing modalities.
