0.05).The cluster analysis of 20 most frequent symptoms was consistent with the frequency analysis in TCM syndrome distribution.Conclusion Age,sex has no relation with the incidence of chronic cholecystitis.TCM syndromes of stagnated heat in liver and stomach and qi stagnation in liver and stomach of chronic cholecystitis are more common.Sex,age,occupation,educational level and whether or with gallbladder stone has no relation with the distribution of TCM syndromes.

ObjectiveTo observe the relativity between cerebral infarction and dyslipidemia in patients with diabetes mellitus (DM).MethodsThe blood glucose and lipid of 66 DM cases and 30 normal healthy persons (as control group) were tested.ResultsIn the blood lipids of the diabetes group without vascular disease, only densities of triglyceride (TG), apolipoprotein A-Ⅰ (apoA-Ⅰ), apolipoprotein B (apoB), apoA-Ⅰ/apoB changed significantly compared with the control group (P<0.05), others without significant change. But blood lipids level of cerebral infarction group was significantly higher than that of the control group (P<0.01). In DM group, the patients with cerebral infarction had higher fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c), TG, low density lipoprotein cholesterol (LDL-ch), apoB, α-lipoprotein (LPα), but lower apolipoprotein A1 (apoA1) and apoA-Ⅰ/apoB than those of the without vascular disease group (P<0.05 or P<0.01).ConclusionDyslipidemia has some relativity with the cerebral infarction of DM.

OBJECTIVE:To observe clinical efficacy of extracorporeal shock wave lithotripsy combined with Paishi decoction in the treatment of kidney stone. METHODS:160 patients with kidney stone were selected and randomly divided into observation group and control group,with 80 cases in each group. Control group only received HB-ESWL-VG extracorporeal shock wave litho-tripsy;observation group additionally received Paishi decoction 300 ml,tid,for consecutive 1 week,on the basis of control group. Clinical efficacy was observed in 2 groups;the levels of serum inflammatory factor IL-2,IL-6,TNF-α,T lymphocyte subset CD3+,CD4+,CD8+ and CD4+/CD8+,erythrocyte immune function indicator C3b receptor rosette(C3bRR),immunity complex ro-sette(ICR)and tumor erythrocyte rosette(TER)level were detected in 2 groups before and after treatment. RESULTS:The effec-tive rate of observation group(98.75%)was significantly higher than that of control group(91.25%),with statistical significance (P<0.05). After treatment,the levels of IL-2,IL-6 and TNF-α in observation group was significantly lower than in control group, the levels of CD3+,CD4+,CD4+/CD8+,C3bRR,ICR and TER were significantly higher than control group,with statistical signifi-cance(P<0.05). Comparsion of CD8+between 2 groups was not statistically significant(P>0.05). CONCLUSIONS:The extracor-poreal shock wave lithotripsy combined with Paishi decoction can relieve inflammation reaction,enhance immune function and im-prove therapeutic efficacy.

Objective To compare the effects of two patient-controlled epidural analgesia(PCEA) after cesarean section and the incidence of nausea vomiting, lethargy and urinary retention. Methods Sixty cesarean section patients were randomly divided into two groups, each group had 30 patients. Group Ⅰ: 0.15% bupivacaine hydrochloride plus tramadoL group Ⅱ: 0.179% ropivacaine mesylate plus nefopam hydrochloride. Postoperative 0-48 hours within the period pain (visual analog score, VAS)and the corresponding time motor block level(the Bromage scale), and incidence of nausea vomiting, lethargy and urinary retention were recorded. Results VAS difference was not statistically significant (P>0.05), Bromage scores in group Ⅱ was shorter than those in group Ⅰ(P<0.05), the incidence rates of nausea vomiting, lethargy and urinary retention in group Ⅱ were lower than those in group Ⅰ(P<0.01). Conclusion Ropivacaine mesylate combined with nefopam hydrochloride PCEA analgesic effect is certain, which shows a clear superiority in the motor function recovery and reducing the incidence of adverse reactions.

OBJECTIVE To investigate the effect of succinate dehydrogenase complex subunit A (sdha)gene on cell proliferation,cell cycle and apoptosis of mouse hepatic cell line BNL CL.2 cells. METHODS The BNL CL.2 cells were transfected by two kinds of sdha-shRNA lentivirus to knockdown sdha gene. The infection efficiency of BNL CL.2 cells infected with lentiviral vectors was analyzed by flow cytometry. The expression of sdha gene and SDHA protein was detected by real-time PCR and Western blotting,respectively. The effect of sdha gene on cell proliferation of BNL CL.2 cells was examined by growth curve,while cell cycle and apoptosis were analyzed by flow cytometry. RESULTS The infection efficiency of BNL CL.2 cells in sh-control group and in sdha-shRNA group was above 80%. Compared with sh-control group,the expression of sdha gene in BNL CL.2 cells infected with sdha-shRNA lentivirus was decreased by about 20 times(P<0.01),the expression of SDHA protein was decreased by about 10 times(P<0.01),and the growth rate was about 70%that of sh-control group(P<0.05). The cells were arrested in S phase,and the percentage of cells in S phase was 0.74 times that of sh-control group(P<0.01). The percentage of cells in G0/GI phase was 1.17 times that of sh-control group(P<0.01). The percentage of cells in G2/M was 1.37 times that of sh-control group(P<0.01). But there was no obvious difference in the apoptosis rate. CONCLUSION The reduced expression of SDHA protein can inhibit the proliferation of mouse hepatic cells,and the inhibitory mechanism may be cell cycle arrest. There is possibly no relationship between inhibition and cell apoptosis.

Objective To study the effect of acute lymphoblastic leukemia (ALL) children bone marrow mesenchymal stem cells (MSCs) on the resistance of K562cell atd mechanism in vitro.Method MSCs were obtained from AL children bone marrow after derivation, cultivation and identification.The coculture of MSCs and K562 and K562 suspension were established.Effects of MSCs on the growth of K562 cells were investigated in vivo.The two kinds of cells treated with different concentration of adriamycin (ADM) and the rate of apoptosis was evaluated by flow cytometry.Cell cycle was determined by flow cytometry.RT-PCR was used to detect Bcl-2 and Bax in K562 cells.Result Compared with the cell growth curve of K562 alone, the K562 cell co-cultured with MSCs grew slower and the exponential phase of growth was not obvious.The apoptosis index of the K562 cells co- clutured with MSCs was (9.19 ±0.53)% examined by flow cytometry, and that of the K562 cells alone was 4.00 ± 0.37% respectively( P ＜ 0.05 ).The percentage of cells at G0/G1 phase was (50.2 ± 2.26) % and that at S phase was (37.03 ± 3.50) % in the group of K562 alone, but those of the K562 cells co - cultured with MSCs were (80.95 ± 3.83) % and ( 17.40 ± 1.50)% respectively( P ＜0.05).The result of RT-PCR suggested expression of Bcl-2/Bax of the K562 cell co-cultured with MSCs was higher than K562 alone.Conclusion ALL children MSCs suppressed the growth of K562 cell in vitro.Adhesion made K562 depress sensitive to ADM.The mechanism was perhaps caused by adhesion with MSCs, K562 cell cycle was changed and related to Bcl-2 gene high level expression.

Objective To investigate the iodine nutritional status,thyroid function and the prevalence of thyroid nodules of residents using non-iodized salt in Ningbo City,Zhejiang Province.Methods In 2011,using typical sampling method,6 villages/communities consumption of non-iodized salt were selected as study fields and residents aged 6-70 were selected as study subjects in Ningbo.Urinary iodine detection,thyroid ultrasound examination and tests of thyroid function [free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)] were performed in all participants.Urinary iodine concentration (UIC) was determined by arsenic cerium catalytic spectrophotometry,and thyroid function was monitored by chemiluminescence method.Results A total of 1 177 residents agreed to participate in the study,482 were male,and 695 were female (including 2 pregnant women).The participants' mean age was (48.54 ± 13.98) years.The median UIC in all participants was 90.36 μg/L,and the proportions with a UIC ＜ 100μg/L was 56.07％ (660/1 177).Furthermore,the median UIC in male was 97.05 μg/L and in female was 83.84 μg/L,there was a significant difference in UICs between male and female (Z =-2.99,P ＜ 0.05).Similarly,significant difference in UICs was observed among age groups (x2 =99.34,P ＜ 0.01).Among the participants,19.88％ had thyroid nodules,with standardized prevalence rate of 13.95％.Furthermore,in male,11.83％ had thyroid nodules,with standardized prevalence rate of 8.11％,and in female was 25.47％,with standardized prevalence rate of 19.83％,there was a significant difference in the detection rate of thyroid nodules between male and female (x2 =33.25,P ＜ 0.01).Likewise,significant difference in the detection rate of thyroid nodules was observed among age groups (x2=49.65,P＜ 0.01),and there was a positive and significant correlation between the detection rate of thyroid nodules and increasing age (x2trend =44.22,P ＜ 0.01).Conclusions The residents who using non-iodized salt in Ningbo City are in the status of iodine deficiency.The detection rate of thyroid nodules is higher in female than in male and it has increased with age.

The kidney stores essence,essence generates marrow is one of the important contents in zaag-xiang theory of traditional Chinese medicine (TCM).The kidney-marrow-brain,kidney-marrow-bone and other biological axis put forward by modern scholars took kidney-marrow system as their cores.Derived from this basis as well as under the guidance of TCM holism concept,the construction of TCM kidney-marrow system has been continuously improved;and the kidney-marrow correlation theory has been enriched.To better grasp and apply the kidney-marrow correlation theory can solve clinical problems of major diseases.However,doctors in past dynasties did not clearly define kidney-marrow system. It has not formed a complete theoretical system.Marrow in the kidney-marrow system contained brain,spinal cord and bone marrow.Marrow can generate blood,which nourishes bone together with the bone marrow.The bone marrow connects with the brain and spinal cord,which are all related to blood.Hence,the function of marrow generates blood occupied an important position in the kidney-marrow system. In this paper,the structure and function of the kidney-marrow system were preliminarily explained and constructed;and the kidney-marrow system related theories were further enriched.

There was preliminary understanding of the kidney-marrow correlation from the pre-Qin to Han dynasty.Until Wei-Jin and Sui-Tang dynasty,the close relationship between kidney-essence-marrow-bone-blood-brain was gradually realized in terms of the structure and physiological function.There was a new anatomical understanding of marrow in the Song,Jin and Yuan dynasty.The concept of spinal cord was put forward for the first time.There was also the etiology and pathogenesis on kidney marrow related diseases.In the Ming and Qing dynasty,there was in-depth understanding on the kidney-marrow correlation.However,the concept of kidney-marrow system was not clearly proposed.Modern scholars summarized traditional Chinese medicine (TCM) theories on kidney stores essence,essence generates marrow,marrow enriches brain,nourishes bone and transfers into blood. Then,the kidney-marrow systemhad begun to take form.It laid a theoretical foundation for the construction of kidney-marrow system..
