Objective:To observe the dynamic changes in serum gastroanteric hormones in patients with stroke complicating stress upper gastrointestinal hemorrhage in acute stage,the changes in acidity,and the changes in gastric empty and to investigate the pathogenetic link of stress pathological change of gastric mucous membrane in patients with stroke(Zhongzangfu,ZZF,中脏腑).Methods:In 20 cases with acute ZZF (Glasgow coma score 6-12 scores) who were all complicating upper gastroenteric bleeding within 24 hours of attack,the levels of motilin(MTL),somatostation(SS),and gastruins(GAS) were measured by radioimmunoassay at the first day (within 24 hours) and the fourth day (within 72-96 hours) respectively meanwhile the gastratube was plased and kept within 24 hours of attack to dynamically observe the pH of gastric juice and the condition of gastric emptying.Results:In comparison with control group the MTL level was significantly increased in patients at the first day of attack (P<0.05),the SS level significantly decreased (P<0.01),and the GSA level had not significant difference (P>0.05).Otherwise the pH (2.87±0.90） of gastric juice in comparison with control group has not significant difference (P>0.05).Among patients in 17 cases the gastric emptying time was prolonged.Even at the fourth day in patients the MTL level was still significantly increased (P<0.01),SS level decreased (P<0.05),and GAS level increased (P<0.01).Conclusions:The upper gastrointestinal hemorrhage in patients with acute ZZF is tightly associated with the changes in MTL and SS but the changes in GAS and gastric pH are not main factor.

OBJECTIVE: To evaluate nasal ventilation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after nasal cavity ventilation expansion techniques by using acoustic rhinometry. METHOD: Thirty-eight patients with mild OSAHS and 17 patients with moderate OSAHS who were diagnosis by PSG were selected. The acoustic rhinometry and rhinomanometry were used to assess the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) before and after the surgery (6 month later). RESULT: The state of mild OSAHS group in NCV, NMCA and NR: before surgery (2.41 ± 1.33) cm³, (0.37 ± 0.39) cm², (2.07 ± 1.48) cmH₂O/(L · min), after surgery (2.53 ± 1.54) cm³, (0.45 ± 0.34) cm², (1.69 ± 1.03) cmH₂O/(L · min), has significant difference (P < 0.05). The state of moderate OSAHS group in NCV, NMCA and NR: before surgery (2.03 ± 1.54)cm³, (0.29 ± 0.39) cm², (3.47 ± 2.56) cmH₂O/(L · min), after surgery (2.31 ± 1.47) cm³, (0.39 ± 0.33) cm², (1.89 ± 1.03)cmH₂O/(L · min), also has significant difference (P < 0.05), while DCAN in two group had no difference (P > 0.05). CONCLUSION There was an objective evaluation of nasal ventilation in OSAHS patients after surgery by using acoustic rhinometry.

Objective To investigate the diagnosis and treatment of the patients with lung cancer hospital-ized in affiliated hospital of Hainan Medical College.Methods A retrospective study was performed from January 1st 2005 to December 31th 2009 in the Hospital.201 patients were enrolled in this study.Results The average onset age of patients with lung cancer was 66 years old.No difference in different gender.The incidence of male was 72.1%, which was higher than of female(27.9%).Male to female ratio was 2.6:1.70.3% of male patients with lung cancer had a history of smoking.146 cases(72.6%)were diagnosed by clinical data,only 55 cases(27.4%)were diagnosed by histopathology.134 cases(66.7%)hadn′t indications for surgery.only 17 cases(25.4%)agreed to have surgery among 67 cases (33.3%)with indications for surgery,50 cases(74.6%)didn't agree to have surgery.34 cases (16.9%)had no indications for chemotherapy.40 cases(24.0%)agreed to have chemotherapy among 167 cases (83.1%)with indications for chemotherapy,but only 14 cases(35.0%)had completed 4 to 6 cycles of chemotherapy, and 26 cases(65.0%)hadn't completed 4 to 6 cycles.8 cases(4.0%)agreed to have radiotherapy.3 cases(1.5%) agreed to have targeted therapy.3 cases (1.5%)transfered to other hospital.Conclusion The ratio of lung cancer patients in male is higher than female in the hospital.smoking is closely related to male patients.Clinical diagnosis rate of patients is high,whereas histopathologic diagnosis rate is low.The rate of the intervention that patients accepted is low and many patients give up available management after the diagnosis is made.

Over the past two decades, multiple drug-resistant infections have escalated globally with the significantly increased morbidity and mortality due to the unreasonable uses of antimicrobial agents in areas such as animal husbandry, industry and medicine. As the situation of drug resistance has been progressively serious, anti-drug-resistant clinical strategies have attracted widely social concerns. This review will report the current status of antibiotic resistance and the mechanism of antibiotic-resistance all over the world. The anti-drug resistance strategies are the emphasis of our report, including the new indication of old antibiotics, the combination of existing antibiotics, the development of new antibiotics, nano-antibiotics, and non-infection treatment with immunomodulators and phage. This review aims to further understand the current situation of drug resistance, which optimizes the strategies of drug-resistant bacteria and clinical services.

OBJECTIVE: To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry. METHOD: Twenty AR cases were selected. Each one was assessed for the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) by using acoustic rhinometry before and after nasal provocation 1 hour and 6 hours later. The results were statistically analyzed. RESULT: After nasal provocation 1 hour 1 later, NCV and NR had a significant difference compared with before nasal provocation(P<0. 05), but NMCA and DCAN had no difference (P > 0.05). After 6 hours later, NCV, NR, NMCA and DCAN had a significant difference compared with before nasal provocation (P < 0.05). NCV,NR,DCAN had a significant difference between 1 hour later and 6 hours later after provocation (P < 0.05), while NMCA had no difference (P > 0.05). CONCLUSION The nasal ventilation in allergic rhinitis after nasal provocation had declined over time.

Objective To determine the prevalence of gastroesophageal reflux disease (GERD) in patients with idiopathic pulmonary interstitial fibrosis (IPIF). Methods From December 2006 to January 2008, 24 consecutive patients with IPIF admitted to Beijing Chaoyang Hospital underwent 24-hour esophageal pH monitoring and esophageal manometry. Meanwhile, 23 patients with diffuse parenchymal lung disease (DPLD) (excluding IPIF) admired to the hospital in the same period served as a control group. Comparison of the prevalence of pathologic esophageal acid exposure GERD symptoms, and ineffective esophageal motility (IEM) between the two groups was made. In this study, nocturnal acid exposure is defined as acid reflux episodes occurring from 10pro to 6am. Results (1) 16 out of the 24 (66. 7%) patients with IPIF were demonstrated to have pathologic esophageal acid exposure; the prevalence of GERD in IPIF patients was significantly higher than that in other DPLD patients, whose prevalence was 26. 1% (P<0.05); (2) 87.5% patients with IPIF and GERD (GERD-IPIF) had nocturnal acid exposure episodes; (3) only 37.5% of the GERD-IPIF patients was found to have typical GERD symptoms such as heartburn and regurgitation; (4) The prevalence of IEM was similar in IPIF and other DPLD patients, being 42.9% and 39. 1% respectively (P >0. 05). Conclusions IPIF patients have higher prevalence of GERD and most of them usually do not show typical reflux symptoms. It is hereby suggested that IPIF patients should be screened with pH monitoring for GERD.
