Functional constipation (FC) is a common functional bowel disorder disease that affects life quality of a large number of people. This study aimed to explore the impact of different intensities of electro-acupuncture (EA) treatment for FC patients. Totally, 111 patients with FC meeting the Rome III criteria were randomly assigned to different intensities of EA groups (low and high intensity of EA groups) and medicine-controlled (MC) group. In EA groups, patients were treated with EA at quchi (LI11) and shangjuxu (ST37) bilaterally for 4 weeks, 5 times/week in the first 2 weeks, and 3 times/week in the last 2 weeks. In MC group, 5 mg mosapride citrate was administered orally 3 times/day for 4 weeks. Spontaneous bowel movement frequency each day was recorded using a constipation diary. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the patients' psychological state. Cortisol (CORT), substance P (SP), and vasoactive intestinal polypeptide (VIP) were evaluated at baseline and at the end of 4 weeks after treatment. As compared with the baseline, there was statistically significant increase in stool frequency every week (P<0.01), but there was no statistically significant difference among the three groups. As compared with the baseline, after 4 weeks of EA therapy, the scores of SDS and serum levels of CORT were decreased significantly in low intensity of EA group (P<0.01), and the serum levels of SP and VIP were increased significantly (P<0.05); the scores of SAS and SDS and serum levels of CORT were decreased significantly in high intensity of EA group (P<0.05), and the serum levels of SP and VIP were increased significantly (P<0.05); the serum levels of CORT and VIP were increased significantly in MC group (P<0.05). As compared with MC group, after 4 weeks of treatment, the serum levels of SP were signifcicantly increased in low intensity of EA group (P<0.01). Low and high intensities of EA could increase the stool frequency, improve the FC patient's anxiety and depression, reduce the serum levels of CORT, and increase the serum levels of SP and VIP effectively. It is concluded that both low and high intensities of EA are effective for FC patients, but there is no significant difference between the low and high intensities of EA.

Objective To explore clinical characteristics and diagnosis of aggressive natural killercell leukemia (ANKL),and evaluate the value of flow cytometry (FCM) in diagnosing it.Methods A case of ANKL was reported and literatures were reviewed.Results The patient presented with persistent high fever,progressive pancytopenia and hepatosplenomegaly.The untypical cells could be seen by morphology.By FCM,NK cells consisted 83.3 ％ of total lymphocytes in bone marrow and immunophenotypes were CD34-,CD2+,CD7+,CD3-,CyCD3+,CD5-,CD16+,CD56+,CD30-,CD4-,CD8-,CD117-,CD11c,CD19-,CD45++,SSC+-++.T-cell receptor (TCR) and IgH gene rearrangement were negative and chromosome was normal.The patient was diagonised ANKL eventually.Conclusions ANKL is a quite rare disease with highly aggressive,poor prognosis and could be misdiagnosed easily.FCM combined with morphology is a convenient,handy,practicable and less invasive device for the diagnosis,and can be a preferred detection technique in some cases.

Objective To analyze the local control rate and the desimetric patterns of local recurrence in nasopharyngeal carcinoma(NPC)patients having been treated with standardized conventional radiotherapy and to evaluate the delineation of rational target volume.Methods From Jan.2000 to Dec.2000,476 patients with untreated NPC were treated by standardized conventional radiotherapy alone at the Sun Yat-sen University Cancer Center.The radiation ports were designed on a X-ray simulator.The nasopharyngeal lesion demonstrated by CT scan and the subclinical spread regions adjacent to the nasopharynx were defined as the target volume.Kaplan- Meier method was used to calculate the cumulative local recurrence rate.For patients with locad recurrence,the primary and recurrent local tumor volumes(V_(nx),V_(recur))were delineated with three-dimensional treatment planning system(3DTPS),and the dataset of radiation ports and delivered prescription dose to the 3DTPS were transferred according to the first treatment.The dose of radiation received by V_(recur)was calculated and analyzed with dose- volume histogram(DVH).Local recurrence was classified as:1.“in-port”with 95% or mere of the recurrence volume((recur)_V_(95))was within the 95% isedase;2.“marginal”with 20% to95% of _(recur)V_(95)within the 95% isedese; 3.“outside”with only less than 20% of _(recur)_V_(95)within the 95% isodose curve.Results With the median follow- up of 42.5 months(range 8～54 months),52 patients developed local recurrence.The 1-,2-,3 and 4-year cumulative local failure rate was 0.6%,3.9%,8.7% and 11.5%,respectively.Among the 42 local recurrent patients who could be analyzed by 3DTPS,52% were in-port,40% were marginal and 7% were outside.For most of the marginal recurrence and all the outside recurrence patients,the main reason of recurrence were related to the unreasonable design of the radiation port and inaccuracy in the interpretation image findings.Conclusions The outcome of better local control rate and the dosimetric pattern of local recurrence show that the target volume is reasonable for NPC in Sun Yat-sen University Cancer Center.Enhancing the capability of correct interpretation of images,accurate design of the radiation pouts and making most useful molecular or functional imaging techniques to escalate the local radiation dose are promising ways to improve the local control further and better.

OBJECTIVETo study the effect of phenformin hydrochloride that may be illegally added in traditional Chinese medicine preparations on the pharmacokinetics of puerarin in rats.

METHODRats were randomly divided into the single pueraria group and the phenformin hydrochloride combined with pueraria group. After oral administration in the two groups, their bloods were sampled at different time points to determine the drug concentration of puerarin in rat blood and calculate pharmacokinetic parameters.

RESULTAfter oral administration with pueraria extracts and phenformin hydrochloride combined with pueraria extracts, the two groups showed main pharmacokinetic parameters as follows: Cmax were (2.39 +/- 1.01), (1.03 +/- 0.35) mg x L(-1), respectively; Tmax were (0.50 +/- 0.09), (1.5 +/- 0.5) h, respectively; Ke were (0.153 +/- 0.028), (0.172 +/- 0.042) h(-1), respectively; t(1/2) were (4.65 +/- 0.86), (4.20 +/- 0.81) h, respectively; AUC(0-t), were (5.73 +/- 2.60), (5.45 +/- 1.81) mg x h x L(-1), respectively; AUC(0-infinity) were (6.72 +/- 2.89), (6.26 +/- 1.88) mg x h x L(-1), respectively. Compared with the single puerarin group, the Cmax was significantly decreased (P < 0.05) and the Tmax was markedly longer (P < 0.01) than the hydrochloride combined with pueraria group.

CONCLUSIONPhenformin hydrochloride can slow down the absorption process of puerarin and change the pharmacokinetic process of puerarin to some extent.

ObjectiveTo investigate the living condition of patients with spinal cord injury (SCI) after Tangshan earthquake.MethodsA questionnaire was designed for the investigation with 41 items including resident environment, income, mood, etc. The faculty of surveillance was composed of trained professionals. 1261 SCI patients living in Tangshan at present, 420 of which live in the sanatoriums and others live in the common families. The patients of four sanatoriums were chosen randomly from fourteen sanatoriums to be investigated in detail, and patients in the common families in two communities, one from city, another from countryside, were also chosen. This investigation was performed in 2003.The results are compared with that of 1988' survey.ResultsGreat improvements in the living condition of SCI patients in Tangshan were shown by the comparison of these two surveys, they were mainly in: the progress in the housing environments (100% SCI patients now live in the specially designed reconstructed houses); better medical services provided (the ratio of wheelchair available from 38.1% to 100%); the majority of the patients in acceptance stage of their disability; the increase of income (21.1% takes up various occupation) with a vigorous spare time; decrease in the common complications with SCI patients; although uremia was still the first death cause of the SCI patients, the percentage was decreased apparently; cardiovascular accident had a higher percentage in the death cause(the second leading cause), implies that the death cause of the SCI survivors had approached the normal person.ConclusionThe improvements reflect the social progress in China. However, still there are some problems to be remained for further solution: the ratio of employment is low; the insurance of living and medical rehabilitation needs further improvement.
