Objective To observe the TCM syndrome changes of lung cancer patients before and after chemotherapy and the effect of Shengxuetang on dealing with side and toxic effects caused by chemotherapy and patient’s immune function. Method Phase III and IV lung cancer patients were randomly divided into two groups, treatment group and control group. Patients in the treatment group were given the combination of chemotherapy and Shengxuetang, while those in the control group were given the combination of chemotherapy and berbamine. Peripheral WBC count, HGB level, platelet count, T-cell count, and NK cell activity were measured, and other toxic effects were observed before and after chemotherapy. Results Before chemotherapy, there were two syndrome types, one is the deficiency of Qi and Yin, and the other is phlegm-damp due to deficiency of Qi accompanied with blood stasis. During the treatment, these two syndrome gradually transformed to the deficiency of both Qi and Yin and coagulation of phlegm and blood stasis. The chance for patients to develop myelosuppression had no difference between two groups, however, most patients in the treatment group developed grade I myelosuppression, while in the control group, most patients developed grade II myelosuppression. G-CSF was prescribed more in the control group than in the treatment group (P

BACKGROUND: Oxygen-derived free radicals are produced during non-enzymatic glycosylation of diabetic protein and accompanied with decrease in nitrogen monoxide (NO) synthesis so as to cause the calcium increase in cell,evacuation of pykno-granule and apoptosis induced by activating endoenzyme.OBJECTIVE: To observe the effects of non-enzymatic glycosylation inhibitor-aminoguanidine on apoptosis of cardiac myocyte and cardiac function in diabetic rats.DESIGN: Completely randomized grouping design and controlled study.SETTING: Pharmacological Department of Jinzhou Medical College.MATERIALS: The experiment was completed at the Central Laboratory of Jinzhou Medical College between September 2002 and March 2003. Totally 54 male SD rats with 2-month old were selected.METHODS: Totally 36 rats were selected to establish diabetic model 60 mg/kg of streptozotocin were injected into the caudal vein. If blood glucose of rats was more than 16.7 mmol/L, the establishment of diabetic model was successful. Model rats were divided into diabetes group and aminoguanidine (AG) group with 18 in each group. Rats in each group were also divided into two 12-week groups with 8 and 12 respectively. Another 18 rats were determined as the control group at 2 time points: 12 weeks (n=8) and 24 weeks (n=10). Rats in each group were fed for 12 and 24in other two groups. Calculation of mass index was [heart (mg)/body mass (g)]. Myocardial tissue of left ventricle was taken out and observed with transmission electron microscope and then stained with in situ end-labeling (ISEL) method. Number of positive nucleus was counted with 10 × 10 ocular lens check system and with 10 fields ISEL method; meanwhile, their average was obtained.MAIN OUTCOME MEASURES: Whether there was apoptosis of cardiac cell and the effect on AG in changes of cardiac structure and function of diabetic rats or not.RESULTS: Eight rats were lost during the experiment because of death mass: That of rats in the 12-week and 24-week diabetic group was higher decrease and increase rate of pressure in left ventricle: That of rats in the 12-week and 24-week diabetic group was lower than that in the control in left ventricle: That in 24-week diabetes group was obviously lower than diabetic group was obviously more than that in AG group (P ＜ 0.01), and that in 24-week diabetes group was obviously more than that in 12-week Apoptosis could be observed in myocardial cell in diabetic group.CONCLUSION: Apoptosis of myocardial cell plays an important role in the development of heart failure in diabetic rats. AG can reduce the apoptosis of myocardial cell and decrease the myocardial pathomorphological abnormality.

BACKGROUND: The blocking treatment can improve the clinic symptom of facial spasm. But the site, depth and the angle of puncturing point are very difficult to be defined, which will seriously infect the curative effect.OBJECTIVE: To study the applied anatomy of the related structures of facial muscle for blocking the facial nerve, and to provide anatomical bases for accurate puncturing point and preventing complications.DESIGN: An observation study based on cadavers and making the mimic puncture and measuring the correlative structures with anatomical method.SETTING: Department of anatomy in a medical college.PARTICIPANTS: Totally 28 adult male cadavers(56 sides) were used and the correlative index were measured.METHODS: The blocking point was located at the convergent point of the interior edge of cartilage of the external acoustic canal, the anterior fringe of mastoid processes and the posterior fringe of mandible ramus, the needle must be thrust vertically to the median sagittal plane. The puncturing needle stopped until it was barred. A longitudinal incision was made from the puncturing point to mandibula angle, and skin, superficial fascia were cut separately. Then carotid superficial fascia was cut from the posterior fringe of parotidean. The facial nerve trunk and the posterior auricular artery were preserved in site. A blunt isolation was made along its incision. Jugular glomus was appeared. Then the correlative index were measured and dealt with statistics method.MAIN OUTCOME MEASURES: The puncturing point, angle and depth,the distance between facial nerve trunk and puncturing point, the position relationship between facial nerve and puncturing needle and the distance relationship between facial nerve and principal structures adjacent to it.RESULTS: The blocking point was located at the convergent point of the interior edge of the external acoustic canal, the anterior fringe of mastoid processes and the posterior fringe of mandible ramus, the needle must be thrust vertically to the median sagittal plane. On the left side, the puncturing depth was (19.91 ± 0.09) mm, On the right side, the puncturing depth was(19.28±0. 10) mm.CONCLUSION: The experimental study could provide accurate puncturing point, angle and depth for blocking the facial nerve and bring the blocking treatment into full play.

Objective To study the changes of amplitude of low-frequency fluctuation (ALFF) of the resting state fMRI in heroin abuser (HD), and discussed its underlying neurophysiological mechanism.Methods The resting state fMRI data of 15 heroin abusers and 15 normal volunteers were analyzed by ALFF.The amplitude of the blood oxygenation level dependent activation of the resting state brain was investigated.The brain structures showing increased and decreased ALFF in TLE patients were demonstrated by comparing to normal subjects with 2-sample t -test with threshold of P＜0.05.Results Compared with normal subjects,the regions showing decreased ALFF in HD patients were distributed in right temporal lobe(45, - 30, -21 ) ,left hippocampus( - 36,- 33, - 6), right thalamus ( 24, - 12,27 ), left posterior cingulum gyrus ( - 15, - 54,24 ), right parietal lobe /precuneus ( 21, - 51,36 ), right inferior parietal lobule ( 21, - 48,78 ) and dorsal lateral aspect of the right frontal lobe(21, - 48,78) ,while ALLF of left(45, - 42,63 ) lateral frontal cortex(0 ,39,72) in HD patients was significantly higher.Conclusion HD shows abnormal brain functional organization in resting state, which may play an important role in the production, maintenance and relapse after withdrawal of heroin abuse.
