International Journal of Traditional Chinese Medicine 2010;32(6):502-503
Objective To study the effect of treating gouty arthritis with Chinese herbal medicines. Methods 64 patients were randomly recruited into a control group and a treatment group, with 32 cases in each group. The treatment group was treated with taking self-made Qingrelishijiedu formula orally and applying Sanhuang powder externally, while the control group was treated with Xinhuang tablets. Results The cure rate of the healing group was 95.45% in comparison with 86.06%in the control group, showing obvious difference (t=3.25, P<0.05). The level of blood uric acid of both group reduced after the treatment. The level of blood uric acid of the treatment group was (498.2±79.1) μmol/L before the treatment and (338.6±39.9 ) μmol/L after the treatment, contrasting to (492.3 ± 87.5 ) μ mol/L and ( 396.2 ± 67.3 ) μmol/L in the control group. The difference was also statistically obvious (t=3.09, P<0.05). Conclusion The effect of treating gouty arthritis by Chinese herbal medicine both orally taken and externally applied was better than western medicine exclusively.

Chinese Journal of Primary Medicine and Pharmacy 2010;17(14):1955-1956
Objective To investigate the sensitivities and the characteristics and the clinical diagnostic values of the electroencephalography(EEG) and brain electrical activity mapping(BEAM) in patients with acute cerebral infarction in early stage. Methods Early stage EEG of 120 patients with acute cerebral infarction were examined in 72 hours and then analyzed and compared with brain CT. Results In the early stages( ≤72 h) of cerebral infarction,the abnormality rate of brain CT was 73.3%, but the EEG abnormality rate was 90%, and there was a significant difference between them(P <0. 01). The focal EEG abnormality and generalized EEG abnormalities with focal changes were mainly noted in the patients. The focal alteration in powers of α and δ frequency bands in BEAM might help localize and lateralize the focus. Conclusion As an inspecting method for patients with early stage cerebral infarction, EEG has high sensitivity, therefore they could be effectively used in early clinical diagnosis and determination of the disease.

China Pharmacy 2005;0(13):-
OBJECTIVE: To investigate the protective effect of polysccharide on sodium nitroprusside-induced neurotoxicity in PC12 cells. METHODS: PC12 cells were cultured and divided into control,damage,PSS(50,100,150 ?g?mL-1) and nimodipine groups. The cell survival was measured by MTT assay. The apoptosis was measured by flow cytometry. The levels of LDH,MDA,SOD,Ca2+i and the caspase-3 activity were determined as well. RESULTS: Compared with the damage group,PSS could significantly reduce cell death rate,lower the efflux of LDH and production of MDA,increase SOD activity,lower the activities of intracellular Ca2+i and caspase-3 activity,and inhibit apoptosis of PC12 cells. CONCLUSION: The remarkable protective effect of PSS on sodium nitroprusside-induced damage of PC12 cells is possibly related to its antagonistic action on intracellular calcium accumulation and anti-peroxidation of lipid.

Objective To evaluate the safety and efficaey of oxaliplatin plus capecitabine combined with concurrent radiotherapy in treatment of locally advaneed oesophageal squamous cell cancer (OSCC).Methods Between July 2003 and December 2008, 46 patients with locally advanced OSCC were irradiated with a dose of 60-64 Gy in 30-32 fractions. The target area included the primary tumor, the lymph nodes with short axis ≥ 10 ram, and the lymphatic drainage region. Two cycles of concurrent chemotherapy was given during radiotherapy, with the oxaliplatin of 85 mg/m~2 on d_1, d_(21), d_(41) and capecitabine of 850 mg/m~2 on d_(1-14) and d_(21-35), which was followed by two cycles of adjuvant chemotherapy. Results The complete re-sponse rate was 33% (14/46), and partial response rate was 56% (24/46), thus the response rate was 88%. Three patients (7%) had no response and 2 patients (5%) had progression. Obstruction relief rate was 90% ,and pain in the chest and back disappeared in 100% of patients. The 1-,2- and 3-year local con-trol rates and overall survival rates were 72% ,40%, 34% and 80%, 45%, 40%, respectively. Acute ra-diation-induced esophagitis rate was 100%, of which 19% was ≥ grade 3. Leuoopenia occurred in 65% of paients and 23% was ≥ grade 3. 23% of the patients had reduced hemoglobin, and 10% with ≥ grade 3.Hand and foot syndrome rate was 16%, and 4% was ≥grade 3.
