Journal of Guangzhou University of Traditional Chinese Medicine 2000;0(04):-
[Objective] To observe the therapeutic effect of kidney-tonifying herbal medicine for chronic aplastic anemia (CAA) and its effect in regulating immune function. [Methods] Twenty-nine cases of CAA were randomized into 2 groups: group A (n = 15) was treated with routine western medicine plus Huosui Tablets and kidney-tonifying decoction for oral use, and Huosui Ointment for external application; group B (n = 14) was treated with routine western medicine only. Three months constituted one treatment course and the two groups were treated for over 2 courses. After treatment, the therapeutic effect was assessed and the changes of peripheral blood counting and immune function indexes were compared with those before treatment. [Results] After treatment, the total effective rate was 80.0% in group A and 42.9% in group B, the difference being significant (P 0.05) . [Conclusion] Kidney-tonifying herbal medicine is effective for the treatment of CAA and its therapeutic effect may be related to the regulation of immune function.

Background and purpose:Zhongshan City is one of the areas with the highest NPC incidence worldwide and nationwide. Although its incidence rate had been analyzed thoroughly, but its mortality rate was not studied further until now. This study was to explore NPC mortality status in Zhongshan City from 1970 to 2010, and to provide scientiifc information for its control and prevention.Methods:NPC death data in Zhongshan City from 1970 to 2010 came from Zhongshan Cancer Registry Ofifce. Such indices as its death number, crude rate, age standardized rate (ASR) and truncated rate etc were calculated and analyzed. Results:There were 5 267 NPC death cases in Zhongshan City from 1970 to 2010, its crude world ASR and truncated rates were 11.03/105, 12.34/105 and 29.31/105 respectively. Its world ASRs increased before 1999 but no statistical signiifcance (P=0.64) and decreased thereafter with obvious statistical signiifcance (P=0.001). But overall, there were a decreasing trend for its ASRs (P=0.001) from 1970 to 2010 in Zhongshan City. Moreover, NPC mortality rate in male was remarkably higher than in female, the death peak age was 55-59 age group, and the different age groups were with different trends fro 1970 to 2010. Conclusion:Although with declining trend from 1970 to 2010, NPC mortality rate in Zhongshan City was at high level worldwide. It suggested that NPC control and prevention should be enhanced.

Objective To study the constituents in Melicope pteleifolia. Methods Plant material was isolated with 80% EtOH. Compounds were separated with chromatographic methods and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, and 13C-NMR) and chemical evidence. Results Five compounds were isolated from petrol ether or ethyl acetate soluble fraction. Their structures were identified as 3,5,3'-trihydroxy-4'-methoxy-7-(3-methylbut-2-enyloxy) flavone (pteleifolosin C, 1), 3,7-dimethoxyl kaempferol (kamatakenin, 2), vanillic acid (3), tricosanoic acid tetradecyl ester (4), and p-sitosterol (5), respectively. Conclusion Compound 1 is a new structure named pteleifolosin C. Compounds 2-4 are isolated from this plant for the first time.

Objective To study mRNA expression of neuroglobin (NGB) in thalamus of DAI rats and explore the relation between NGB and heed injury. Method 46 male SD rats were randomly divided into four groups. The DAI model was established according to modi-fied Mamamu method. The mRNA expression of NGB in thalamus at different time point after injury was detected by RT-PCR method. All data were analyzed with statistical software. Result The mRNA expression of NGB in thalamus increased obviously from 30 minutes after in-jury while decreased at the 24th hour after injury. But the expression increased again and reached peak at the 48th hour after injury. Conclu-sion The mRNA expression of NGB in thalamus increased after DM. Those changes suggested NGB might participate in the response mech-anism of stress, secondary ischemia and hypoxic brain injury after neuron injury.

Objective:To analyze the clinical and physical tactors associated with acute bone marrow suppression in concurrent chemo-radiotherapy for rectal cancer and to provide a reference standard for the best clinical treatment plan. Methods:Retrospective analy-sis was performed on 62 patients with rectal cancer who received concurrent radiotherapy and chemotherapy in our department. The pelvis was contoured for each patient in the radiotherapy treatment planning system and divided into three subsites: lumbosacral spine, ilium, and lower pelvis. Prognostic clinical and physical factors were analyzed by univariate and multivariate analyses. Evaluated prognostic clinical factors included sex, age, clinical stage, original hemoglobin levels, and chemotherapy, operation, and radiation modes;physical factors included V5, V10, V15, V20, V25, V30, V35, V40, V45, V50, Dmax, and Dmean of lumbosacral spine, ilium, low-er pelvis, and pelvis. Results:The percentage of patients who developed acute bone marrow suppression (≥2 grade) was 61.3%(38/62).Univariate analysis of related factors revealed statistically significant differences were sex, chemotherapy, lumbosacral spine V45, il-ium V20, and ilium V30. Multivariate logistic regression analysis indicated that chemotherapy and ilium V30 are the risk factors for acute bone marrow suppression. The receiver operating curve showed that the threshold of ilium V30 was 44%. Conclusion:Acute bone marrow suppression is influenced by more than one factor;local control rate of the tumor and acute bone marrow suppression are tradeoffs in rectal cancer treatment. An appropriate chemotherapy method should be selected, and ilium V30 must be maintained below 44%to prevent bone marrow suppression in rectal cancer patients.
