Objective To explore the relevance between resting heart rate (RHR) and metabolic syndrome in young and middle-aged patients with essential hypertension.Methods Three hundred and forty patients with essential hypertension were enrolled in this study.According to the RHR,the hypertension patients were categorized into 3 groups:group RHR 1 (RHR ＜ 70 bpm,52 cases),group RHR 2(RHR 70-85 bpm,168 cases) and group RHR 3 (RHR ＞ 85 bpm,120 cases).The RHR,blood pressure,fasting blood glucose,triglyceride,high density lipoprotein cholesterol,2 h postprandial blood glucose and waistline were determined and compared.Results The level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure,diastolic pressure,and high density lipoprotein cholesterol in group RHR 1 were (4.96 ± 0.65) mmol/L,(6.85 ± 0.51) mmol/L,(1.69 ± 0.43) mmol/L,(78.3 ± 6.5) cm,(143.2 ± 5.6) mmHg (1 mmHg=0.133 kPa),(85.4 ±5.2) mmHg and (1.08 ±0.64) mmol/L.In group RHR 2 they were (5.66 ± 0.77) mmol/L,(7.94 ± 0.66) mmol/L,(2.58 ± 0.75) mmol/L,(88.6 ± 7.3) cm,(156.7 ± 6.1) mmHg,(93.6 ± 4.7) mmHg,and (0.95 ± 0.59) mmol/L.In group RHR 3 they were (6.85 ± 0.73) mmol/L,(8.97 ± 0.59) mmo]/L,(3.52 ± 0.90) mmol/L,(95.8 ± 9.2) cm,(164.3 ± 7.4) mmHg,(101.2 ± 3.5) mmHg and (0.78 ± 0.33) mmol/L.With the increase of RHR,the level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure and diastolic pressure increased step by step,high density lipoprotein cholesterol decreased step by step,and there were significant differences (P ＜ 0.05).Correlation analysis showed that RHR was positively correlated with fasting blood glucose,2 h postprandia blood glucose,triglyceride and waistline (r =0.52,0.45,0.50,0.36,P ＜ 0.05),and negatively correlated with high density lipoprotein cholesterol(r =-0.39,P ＜ 0.05).Conclusion RHR is closely related to the metabolic disorder in young and middle-aged patients with essential hypertension,and doctors should pay attention to the heart rate control while lowering blood pressure.

Pulmonary embolism(PE)is a relatively common cardiovascular emergency.Haemodynamic instability is the characteristics of massive pulmonary embolism,with a mortality as high as 20%.The goals of PE treatment are to remove the thromboembolic obstruction rapidly,exert beneficial effects on haemodynamic parameters and save the lives of patients.Haemodynamic and respiratory support is of vital importance in some critically ill patients with PE.The basic treatment is anticoagulation,the methods of which are different for PE during pregnancy,among cancer patients,with right heart thrombi and with heparin-induced thrombocytopenia.

Objective To optimize the medium for rhizomatous induction of Belamcanda chinensis in vitro. Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.

The neonatal burst suppression is a severe EEG pattern and always demonstrates serious damage of nerve system. But the outcome of these patients depends on the different etiology. A total of 256 cases of video EEG recordings were analyzed in order to summarize the etiology and outcome of burst suppression. The results showed that some patients in all 17 cases of burst suppression showed EEG improvement. The etiology was the dominant factor in long term outcome. It was suggested that effective video EEG monitoring is helpful for etiologic study and prognosis evaluation.

Results 26 cases treated by emergency endoscopic hemostasis were successful, the success rate was 96.30 %. Conclusions Prevention is very important for duodenal papilla hemorrhage. Once bleeding after ER-CP, emergency endoscopic hemostasis is the most direct, simple and effective measure.

Targeted cancer therapy is one of the modalities to increase efficiency and decrease adverse effects of chemotherapy,and the selection of drug vector system is of importance for targeted therapy.An ideal adriamycin targeted vector system should have maximal efficacy and minimal adverse effects in inhibiting cancer cells through different mechanisms.This article reviews the recent progress in adriamycin targeted therapy,including the modes of adriamycin administration,the selection of drug vectors,as well as other chemotherapeutic drugs in targeted therapy of liver carcinoma.

Objective:To analyze the diagnosis and treatment of 1 case of primary bone marrow diffuse large B cell lymphoma (DLBCL),and to provide the reference for its dignosis and treatment. Methods:Combined the medical history and other auxiliary examination results, the possibility of diagnosis of primary bone marrow lymphoma (PBML)was suspected. Bone marrow biopsy and immunohistochemistry were carried out for diagnosis, and R-CHOP (rituximab, cyclophosphamide,doxorubicin,vincristine,and prednisolone) was selected as the chemotherapy scheme. Results:The diagnostic basis of the case was in accordance with the diagnostic standard of PBML.According to the results of immunohistochemical staining,it was classified as the DLBCL subtype. Then the patient received 6 cycles of R-CHOP immune chemotherapy. Complete remission of bone marrow cell morphology was gained after the first cycle of R-CHOP treatment,and the patient was treated for another five cycles and the complete remission was retained in 3 months of follow up after drug withdrawal. Conclusion:Bone marrow biospy and immunohistochemistry have the unique diagnostic values for primary bone marrow DLBCL,and the regimens containing rituximab may provide a ideal efficacy during short term observation.

BACKGROUND:Studies have shown that human umbilical cord mesenchymal stem cel s can improve pulmonary ventilation function by reducing inflammations. OBJECTIVE:To observe the therapeutic effect of human umbilical cord mesenchymal stem cel transplantation on acute lung injury. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and experimental group. Rats in the latter two groups were used to establish animal models of acute lung injury by intratracheal instil ation of lipopolysaccharide. One hour after modeling, rats in the experimental group were intratracheal y administered human umbilical cord mesenchymal stem cel suspension (0.1 mL, 1×106 cel s), and those in the other two groups were given normal saline in the same dose intratracheal y. Twenty-four hours after treatment, the pathological changes of lung tissue were observed using hematoxylin-eosin staining;the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were detected. RESULTS AND CONCLUSION:Compared with the normal group, the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were significantly increased in the model group (P<0.05), while compared with the model group, these levels were significantly decreased in the experimental group (P<0.05). Hematoxylin-eosin staining results showed clear alveolar space structure with complete alveolar septum in the normal group. In the model group, the alveolar septum was markedly thickened, and there was visible pulmonary capil ary hyperemia, edema, as wel as a large amount of inflammatory cel infiltrations in the pulmonary capil aries and alveolar space. Edema fluid rich in proteins was observed in a part of the pulmonary alveoli, and an extensive transparent membrane formed in the alveolar space. In the experimental group, the alveolar structure was clear, but the alveolar septum became thickened, and red blood cel s and a smal amount of infiltrated inflammatory cel s were leaked from the pulmonary interstitial tissue. In conclusion, human umbilical cord mesenchymal stem cel transplantation for treatment of acute lung injury can reduce inflammatory factor levels and al eviate lung injury.

ObjectiveTo investigate the diagnosis and operative procedure for spontaneous perforation of congenital choledochal cyst in children. MethodsThe clinical data of 16 cases with spontaneous perforation of congenital choledochal cyst were analysed retrospectively.ResultsAll cases were under 4 years old with a mean age of 23 months. Abdominal distension, pain, vomiting, fever and diffuse tenderness were present in all patients. The preoperative diagnosis was established by paracentesis in ten patients. Abdominal sonography and CT found a cyst in 5 of the 10 cases reviewed. In 11 cases (68.7%), the site of perforation was found on the confluence of common bile duct and gallbladder cystic duct. T-tube drainage was used as a transition measure. All patients recovered uneventfully. Radical resection was performed in about three months after the initial operation. ConclusionsThe obstruction of the bile duct and poor blood supply to the choledochal cyst are major causes leading to perforation. Routine abdominal paracentesis should be carried out for a small child with peritonitis and general abdominal tenderness, especially on the right upper quadrant.T-tube drainage should be adopted as an emergent procedure to tide the patient over the crisis followed by elective choledochal cyst resection and bile duct reconstruction.
