Objective To verify the clinical effect of Qinghuang powder in chronic myelogenous leukemia(CML). Methods 86 CML patients treated with Qinghuang powder, in which 28 cases also partially received herbal medicine (activating blood circulation to dissipate blood stasis). Results 62 cases had complete remission (72.1%), 14 cases partial remission (16.3 %), advance 8 cases(9.3 %), inefficiency 2 cases (2.3 %), and the total efficiency was 97.7 %. The symptom were improved after a week when patients had taken medicines. 44 cases have hepatomegalia, among them 39 cases have diminished or became normal compared to untreated. 70 cases have splenoparectasis, among them 60 cases became normal, 9 cases diminished, and 1 case had no change after treatment. It took 15.5 days in average when spleen began to diminish, and took 62.9 days to become smallest. The WBC began to decrease at 10.4 day and took 54.8 days in average became normal. The major side effect was digestive tract symptom, followed by skin pigmentation and skin excessive cornification. It could be avoided by low dosage. Conclusion Qinghuang powder could not only induce CML to CR, but also improve the clinical symptom of CML and eliminate the infiltration of leukemia cells. It has little influence to Hb and Plt.

Objective To determine the efficacy of liver cancer resection combined with splenectomy for patients with hepatocellular carcinoma with hypersplenism.Methods Among 35 patients with hepatocellular cancer and hypersplenism treated from March 2004 to January 2006 at our hospital,12 patients accepted simultaneous liver cancer resection and splenectomy (the splenectomy group)and 23 only accepted liver cancer resection (the non-splenectomy group).The liver function,platelets and white blood cells were analyzed retrospectively.Results All the operations were successfully carried out.Within 1 week after operation,the white blood cell count increased from (3.2 ± 1.7) × 109/L to (8.5±-5.3) × 109/L,the platelet count increased from (52.6±23.7) × 109/L to (245.3±94.6) ×109/L(P＜0.01) in the group of patients with combined splenectomy,while little change occurred in the non-splenectomy group.The liver function in the splenectomy group recovered to the preoperational value within 1 week.Two years after operation,7 (58.3％) patients were still surviving in the splenectomy group and the mean tumor-free survival was (16.4 ± 4.3) months compared with (14.3 ±5.2) months in 10 (43.5％) patients in the non-splenectomy group,(P＜0.005).Conclusion Liver cancer resection combined with splenectomy was efficacious to hepatocellular cancer with hypersplenism.

In order to regulate the apoptosis induced by Fas-FasL system, a soluble isoform of mouse Fas was cloned from thymocytes of immature mice with the primers designed according to the full-length Fas cDNA sequence in the GeneBank. It was directionally inserted into the intermedium vector pUC19. DNA sequencing proved that it was consistent with the expected sequence. Then it was subcloned into the eukaryotic expression vector pCA13, which was used to construct the recombinant vector pCA13-FasC. By lipofectamine (LF2000)-mediated transfection, pCA13-FasC was transfected into the 293 cells. RT-PCR and Western blot indicated that the murine soluble Fas C protein was expressed in the 293 cells. Apoptosis inducing test showed that the expression of this murine Fas C could block the Fas-induced apoptosis, which confirmed the biological activity of the recombinant Fas C.

Objective To review the role of extrahepatic bile duct resection in patients with hepatocellular carcinoma with bile duct tumor thrombi.Methods The Pubmed,Wan Fang and China Science and Technology Journal Database were reviewed systematically.Any case reports or studies involving treatment of hepatocellular carcinoma with bile duct tumor thrombi were included in this literature search.Two authors independently assessed the studies for inclusion and extracted the data.Univariate analysis was used to compare the baseline characteristics and the Kaplan-Meier method was used for analyzing survival and diseasefree survival outcomes.Results Using predetermined inclusion criteria,16 studies which included 170 patients entered into this study.All these patients underwent surgical resection of hepatocellular carcinoma and bile duct tumor thrombi.Based on the Satoh classification,45 patients were type Ⅰ,107 patients type Ⅱ and 18 patients type Ⅲ.Twenty-four patients underwent liver resection combined with extrahepatic bile duct resection.The remaining 146 patients underwent liver resection combined with thrombectomy.The 1-,3-,and 5-year survival rates of all the patients were 73.4％,41.5％ and 21.8％,and the corresponding recurrences free survival rates were 62.5％,29.2％ and 13.1％,respectively.On Kaplan-Meier analysis,there were no significant differences in the survival outcomes between the 2 groups of patients,(P ＞ 0.05).The 1-,3-,and 5-year survival rates of the extrahepatic bile duct resection group were 66.7％,41.7％ and 12.5％,and those of the thrombectomy group were 74.6％,41.3％ and 23.8％,respectively.On subgroup analysis (Satoh type Ⅱ and Ⅲ),no significant differences were observed between the two groups (P ＞0.05).The 1-,3-,and 5-year survival rates of the extrahepatic bile duct resection group were 65.2％,38.0％ and 13.0％,and those of the thrombectomy group were 72.8％,39.5％ and 20.9％,respectively.Conclusion Extrahepatic bile duct resection did not improve the overall survival of patients with hepatocellular carcinoma with bile duct tumor thrombi.

Objective? To explore the knowledge level of hospital infection control in nurses of key clinical departments and to provide a reference for providing more targeted hospital infection training. Methods? The nurses of key clinical departments in Beijing Tiantan Hospital, Capital Medical University in December 2017 were selected by convenient sampling and investigated with the self-designed hospital infection knowledge questionnaire. t test and variance analysis were used to compare the knowledge level of hospital infection between nurses with different characteristics. Results? The score for hospital infection knowledge in the 872 nurses from key clinical departments was (20.34±3.21), and the score in 61.58% of them was ≥20;the highest scoring rate was found in hand hygiene, while the lowest scoring rate was found in infectious disease knowledge and diagnosis; and there were statistical differences in knowledge level of hospital infection between nurses from different departments and with different professional title, educational background and students to teach or not (F/t=4.39, -3.69, -3.13, 5.24; P＜0.05). Conclusions? The knowledge level of hospital infection control in nurses of key clinical departments stands at a low level. Targeted training should be provided to nurses with different characteristics. Multiple management measures need to be taken to strengthen the supervision and monitoring over these departments, enhance the infection control ability in nurses from key departments, and prevent hospital infection.

ObjectiveTo evaluate the dynamic disinfection effect of the upper-room 222 nm ultraviolet radiation on the air in different areas of the emergency department, and to provide references for a new solution of air disinfection that man-machine coexisted in the medical and healthcare institutions. MethodsThe upper-room 222 nm ultraviolet radiation air sterilizers were installed at a height of 2.3‒2.6 m from the ground in the observation room, computed tomography (CT) scanning room, rescue room and consulting room of the emergency department in Beijing Tiantan Hospital, Capital Medical University . The test area was divided into a 222 nm ultraviolet group and a control group according to whether the 222 nm ultraviolet germicidal air disinfection was conducted or not. The experimental group started air disinfection at8:00 a.m., and the air sampling was conducted from 9:00 a.m. to 16:00 p.m., with a 10 min sampling interval of every 1 hour. While the control group only collected air sample with the same air sampling method used in the experimental group, without air disinfection. The air microbial sampler with six-level sieve impingement was used for the air sampling, and the differences in the total number of airborne bacterial colonies were compared between the two groups. ResultsA total of 128 air samples were collected in the trial, of which 64 were from the experimental group and 64 from the control group. The total number of airborne bacterial colonies in the experimental group was lower than that in the control group (all P<0.001), and was maintained at a lower level throughout the entire period. The killing rate of 222 nm ultraviolet radiation to airborne microorganisms was approximately 55.76% to 76.33% in different sampling areas. The qualified rates of the total number of dynamic airborne bacterial colonies in the observation room, rescue room and consulting room were improved from 12.50%, 37.50% and 25.00% to 81.25%, 100.00% and 100.00%, respectively (all P<0.001). Over 62.50% of the time, the air quality in the consulting room and CT room in the 222 nm ultraviolet group met the environment standards for airborne bacterial colony criteria of class Ⅰ or class Ⅱ. ConclusionThe upper-room222 nm ultraviolet radiation germicidal disinfection can effectively reduce the total number of airborne bacterial colonies and improve the environment for emergency department, and the continuous using of it is helpful for keeping the air safe and clean.
