Crystal structures of chemical drugs has been being investigated widely. But few attention has been paid to polymorphs-phenomena of active ingredients from Traditional Chinese Medicine(TCM). Taking anhydrous dehydroandrographolide and hydrousprim-O-glucosylcimifugin as example, differences between TCM reference substances (RSs) with different crystal structures were discussed by using microscopy, melting point determination, differential thermal analysis (DTA) and infrared (IR) methods. The results showed that different crystal structures could lead to change of melting points, thermal behaviors and IR spectrum. It's indicated that polymorphs may be considered if different physicochemical properties were obtained when applying TCM RS. Differences of chemical properties of active ingredients from TCM with different crystal structures need further investigation.

ObjectiveTo investigate the effects of community-based rehabilitation simple technique on motor function, balance function of stroke.Methods48 stroke patients from Guangwai Hospital in Beijing were divided into two groups: test group(n=26) and control group(n=22). The test group received community-based rehabilitation simple technique combining with routine therapy, while the control group only received routine therapy. All patients were assessed with the scale of motor function (Fugl-Meyer Assessment, FMA) and Fugl-Meyer Balance Assessment (FMA-B) before, 1 month, and 3 months after treatment respectively.ResultsThere were no significant difference between two groups in FMA and FMA-B (P>0-05) before and 1 month after treatment. The scores of FMA and FMA-B improved significantly (P<0-05) 3 months after treatment.ConclusionCommunity-based rehabilitation simple technique is effective to improve motor function and balance function of stroke patients.

OBJECTIVETo investigate the prevalence and subtypes of microdeletions in azoospermia factor (AZF) region in infertile men from Sichuan in order to correlate genotypes with phenotypes.
METHODSMultiplex-PCR was used to detect sequence tagged sites (STS) of AZF microdeletions in 1011 infertile men including 713 cases of non-obstructive azoospermia and 298 cases of severe oligospermia.
RESULTSThe overall prevalence of microdeletions was 10.48% (106/1011), and the deletion rates were 11.08% (79/713) in non-obstructive azoospermia and 9.06% (27/298) in severe oligospermia. Complete AZFa or AZFb deletions were associated with azoospermia, whereas AZFc deletion (60.38%) was the most frequent deletion. The deletions were associated with variable spermatogenic phenotypes, and 37.50% of the patients with a deletion had sperms in the ejaculate. A mild decline in sperm concentration was found in two cases with partial AZFb deletion and one case with partial AZFb-c deletion.
CONCLUSIONDeletions of the AZFc region were most commonly found in our patients. All cases with complete AZFa or AZFb deletions and a proportion of cases with AZFc deletion were associated with azoospermia. Our study has provided more insight into the genotype-phenotype correlation, and confirmed that Yq microdeletion screening has a significant value for the diagnosis for male infertility.

OBJECTIVETo explore the in vitro anti-platelet effects of Ginsenoside -2A,a purified extract from Panax notoginseng.
METHODSPlatelet rich plasma (PRP) was prepared routinely from venous blood samples of patients with essential hypertension and normal persons. PRP was incubated with different concentrations of Nifedipine, Ginsenoside-2A ,and SK&F96365. Maximal platelet aggregation rate[ PAG (M) ] induced by 2 micromol/L ADP was taken as the observed index. Five-minute PAG( M) was determined for 5 consecutive times.
RESULTS(1) PAG (M) in essential hypertension group was 0. 89 +/- 0. 06, which was higher than that in the normal group (0. 68 +/-0. 07 ) with significant difference (P <0.01). (2)Nifedipine of two concentrations (10 p.mol/L,20 pVmol/L) had no effect on PAG(M) in either essential hypertension group or normal group(P >0. 05). (3)Different concentrations of SK&F96365 (2.5 micromol/L,5 micromol/L,10 micromol/L and 20 micromol/L) could inhibit the PAG(M) in essential hypertension group; (4) Differen concentrations of Ginsenoside -2A (2. 5 micromol/L, 5 micromol/L, 10 micromol/L and 20 micromol/L) could inhibit PAG ( M) in essential hypertension group; three concentrations of Ginsenoside -2A (5 micromol/L, 10 micromol/L, 20 micromol/L) could inhibit the PAG(M) in the normal group (all P <0.05).
CONCLUSIONPlatelet aggregating function in essential hypertension patients was obviously higher than that in the normal persons and platelets was in the high reactive status. Nifedipine had no inhibitive effect on platelet aggregation. SK&F96365 could inhibit the platelet aggregation. Ginsenoside-2A could inhibit platelet aggregation, and had the definite anti-platelet action.

AIM: To study caspase-9 expression on rat retina in the process of chronic elevation of IOP and the changes with the application of amino guanidine (AG), thus to investigate potential protective function of AG to rat retina with chronic elevation of IOP.METHODS: Immunohistochemistry, RT-PCR and Western blot were used to observe retinal morphology and expression of caspase-9 at different time points of rat with chronic IOP elevation, both affected or not affected by the application of AG.RESULTS: Compared with control group, as time passed retina of experimental group gradually had detectable morphological changes. On 21st day of chronic IOP elevation, retinas became thinner and the quantity of retinal ganglion cells (RGCs) decreased; caspase-9 expression increased, consistent with the morphological changes. The group using AG presented relatively smaller morphology changes and less expression of caspase-9.CONCLUSION: Apoptosis-related gene caspase-9 played a part in the process of chronic IOP elevation; AG protects retina by down-regulating expression of caspase-9.

Objective To improve the quality of the management of the elderly patients with cancer in Sichuan province,and to understand the attitudes and perspectives of elderly surgeons and oncologists for the management and treatment of elderly patients with cancer.Methods A face-toface questionnaire interview was conducted with oncologists (n 64) and geriatricians (n =64).128 physicians were involved in this study.Results The cancer management and therapeutics were deemed appropriate at present by 9.38% (6/64)of the geriatricians and 25.00% (16/64)of the oncologists.The 39.06% (25/64) of geriatricians used to notice geriatric syndromes,while 81.25% (52/64)of oncologists never concerned about the geriatric syndrome(P=0.011).As for the causes of the therapy-associated toxicity,oncologist versus geriatrician payed an attention to malnutrition (100.00% vs.100.00% in both groups),to mobility disorders(65.63% vs.65.63%,84/128 in both groups),to cognitive impairment/mood disorder (89.06% in geriatrician group vs.75.00% in oncologist group,P=0.038).For the factors affecting treatment decisions,a physical ability attention (oncologists vs geriatricians:70.31% vs.92.19%;P =0.002),and comorbidity (oncologists vs geriatricians:62.50% vs.79.69%,P =0.032) had statistically significant difference.In addition,lack of geriatrics knowledge was also reported by more oncologists.However,one hundred percent of participants wanted very much to cooperate with each other in their clinical work.When responding to the clinical scenario,the 10.94% (7/64)of geriatricians and 32.81% (21/64)of oncologists chose modified treatment for 65-74 years old patient with cancer(P =0.003).When the age of the patients was 75-84 years old,only 12.50 % (8/64) of geriatricians prefer end-of-life care,while 31.25 % (20/64) of oncologists chose it (P =0.010).Conclusions Selection of treatment decisions in the elderly patients with cancer affect by ageing.Both oncologists and geriatricians are concerned with the elderly patients with cancer,ageing syndrome,total sickness and functional status.And these doctors support an establishment of a multi disciplinary team cooperation for the elderly patients with cancer.Therefore,the establishment of mutual cooperation between the two professionals is necessary and feasible.
