Objective　The effects of endotoxemia on hepatic energy metabolism and hepatic tissue blood flow were studied on the rats with obstructive jaundice.Methods　 After biliary obstructed and decompressed the rats were injected endotoxin,then hepatic tissue blood flow and energy metabolism were determined.Results　Hepatic blood flow decreased and hepatic energy metabolism lowered in rats with obstructive jaundice.Hepatic blood flow decreased markedly and hepatic energy metabolism lowered further due to endotoxemia. Afeter 4 weeks of jaundice hepatic energy metabolism did not recover.Conclusion　The decrease in hepatic tissue blood flow affected notably hepatic energy metabolism in obsturctive jaundice.When obstructive jaundice with endotoxemia happened,hepatic tissue blood flow markedly deceased and energy metabolism lowered further.

Objective To observe the hemodynamic changes on right ventricular hypertrophy induced by monocrotaline in rats . Methods Male SD rats were given monocrotaline 60 mg/kg by a single intraperitoneal injection ,the mRNA expression of RV/BW , RVHI and ANF were took as the indicators .Intraperitoneal injection with 10% chloral hydrate was performed ,the artery cannulae and right ventricular catheter were inserted ,and the right ventricle pressure was measured .Results The RVHI and RV/BW were significantly increased in M2W and M4W groups ,compared with vehicle control (P<0 .01) ,and the ANF mRNA expression was significantly increased in both groups .Bp and HR did not change in model groups .RVEDP markedly decreased (P< 0 .01) and RVP ,± dp/dtmax ,t dp/dtmax and Vpm increased (P<0 .001) in M2W groups ;and all parameters increased significantly in M4W groups (P<0 .01) .Conclusion Monocrotaline can induce RVH ,which accompany hemodynamic changes and the systolic and dias‐tolic dysfunction in right ventricle may eventually cause right heart failure .

Barriers to doctor-patient communication induced medical disputes easily.Operation is one of the main means for surgical treatment.Surgery has a high incidence of medical disputes for its invasive and high-risk nature in operative treatments.In the course of surgical treatment,we place patients at the center of medical services and carry out the communicating model of "empathy" in doctor-patient communication to reduce the somatopsychic suffering of patients and promote mutual understanding and support between doctors and patients.It proves to help build a harmonious relationship between doctors and patients,reduce medical disputes,advance the quality of medical services and put the relationship between doctors and patients in a win-win situation.

OBJECTIVE:To evaluate the initial and acquired resistance level of lung tuberculosis in Shenzhen.METHODS:Culture-positive of sputum specimens of1948cases of lung tuberculosis were collected in Shenzhen from1999to2002and the resistance of tubercle bacillus in sputum-positive to four anti-tuberculosis drugs(isonicotinylhydrazide INH,streptomycin SM,rifampin RFP,Ethambutol EMB)were tested by WHO guideline.RESULTS:The total rate of tubercle bacillus to drug resistance was35.06%,initial drug resistance rate34.01%,initial multi-drug resistance rate4.97%,acquired re?sistance rate45.51%,and acquired multi-drug resistance rate12.92%.Acquired resistance rate of tubercle bacillus to each of4drugs was on the rise to different extents as compared with initial resistance rate.The rise was39.91%for SM,94.07%for INH,44.04%for EMB,and118.18%for RFP.CONCLUSIONS:The initial drug resistance rate ranks higher in Shenzhen as compared with the average level in the whole nation,resistance rates of RFP and INH double after combined administration.

The interaction between the immune system and nervous sytem affcts nervous function.There is a close relationship between the episode of epilepsy and immunity,the molecular basis of which is the network of cytokines.In order to quest new methods of contolling epilepsy by regulating the network of cytokines,the roles of several cytokines in the ocurrence and onset of epilepsy were reviewed in this article.

Objective To investigate the pathogens and drug resistance of bacteria in children with pneumonia in Chongqing by using antibiotic reasonably.Methods Bacteria identification antibiotics sensitivity test were performed in samples of lower respiratory tract secretions from 780 cases by microscan automatic analysis machine.At the same time,respiratory virus,chlamydial and mycoplasmal pneumoniae were tested.Results The pathogens were found in 433 cases.Three hundred and sixty-four strains bacteria were isolated,116 cases were infected by virus and 26 cases by mycoplasmal pneumoniae.The resistant rates of staphylococcal and Klebsiella pneumoniae were high.The resistant rate of Streptococcus pneumoniae to penicillin was high.Haemophilus parainfluenzae was sensitive to cephalosporins.Conclusions In Chongqing,children′s pneumonia is mainly caused by bacteria.The sensitivity of antibiotic varies from different bacteria.Finding pathogens and monitoring drug resistance have taken great advantage to antibiotic selection and have prevented rapidly growing of resistant strains.

Objective To explore the feature of clinical and laboratory and therapy in childern with idiopathic pulmonary hemosiderlsis(IPH).Methods The clinical and laboratory datas of 50 cases with IPH were studied from Jan.1996 to Jan.2006.The hemogram,the metabolism of ferrum,the cellular test of bone marrow,finding the hemosiderin cells in sputum or gastric juice or bronchovesicular juice and ma-nifestation were analyzed.Results IPH were often found in children aged 6 to 14 years old.Coungh and spitting blood and anemia were the most important clinical feature.X-ray manifestations were various.The diagnosis of IPH was based on clinical feature and finding out the he-mosiderin cells in sputum or gastric juice or bronchovesicular juice.X-ray and CT manifestations were important.At the same time,the secon-dary IPH was removed.The clinical symptom of IPH were relieved by using adrenal cortical hormone.Conclusions There is no specificity in children with IPH.X-ray,CT manifestations and finding the hemosiderin cells in sputum or gastric juice are helpful in diagnosis.Using adrenal cortical hormone will release symptom and prognosis.

Totally 1 patient were selected from Beijing Xishan Institute for Neuroregeneration and Functional Recovery in Shijingshan District in May 2006. The patient received acupuncture treatment in trideca-ghost points after olfactory ensheathing cells (OECs) transplantation. Detailed acupuncture method and acupuncture point were as follows: Acupuncture was performed from left side on Shuigou (DU 26), Jiache (ST 6), Fengfu (DU 16), Chengjiang (RN 24), Shangxing (DU 23), oblique needling from Shuigou to mittele muschel 0.3 cun. Needle insertion on Chengjiang was from left to right, for 1 minute without retaining needle. Then acupuncture on Shaoshang (LU 11), Daling (PC 7), Jianshi (PC 5), Quchi (LI 11) of both sides, and lower limbs: Yinbai (SP 1) and Shenmai (BL 62) was conducted. Acupuncture on Jiache and Quchi was retained until the patient vellicated limbs. Punctured on Dicang (ST 4) if the patient had spasm on angulus oris, about 20 minutes every time, once a day. After the treatment, the patient had some improvements in the consciousness and electrophysiology. Significant pain reaction appeared, and the endings of extremities had some little movement. The patient could turn head and twist shoulder. Evoked potential in electromyogram (EMG) had certain amelioration.
