This paper collected the traditional Chinese medicine (TCM) prescriptions of osteoporosis and osteoarthritis from CNKI to set up database and used TCM inheritance system to analyze the composing principles in prescriptions. We collected 103 and 106 prescriptions for osteoporosis and osteoarthritis respectively, then analyzed inherent principles between herbs in prescriptions by using the TCM inheritance system, and obtained the frequency of each herb, and drug combinations of two diseases' prescriptions. The result showed that the principles in TCM prescriptions of osteoporosis and osteoarthritis are similarities, buch as tonifying kidney and invigorating the circulation of blood, but differences of the specific drugs. That is to say, tonifying kidney is the main method of osteoporosis treatment, however, invigorating the circulation of blood is the main method of osteoarthritis treatment.

Objective By detecting the DNA methylation and gene expression of long-chain 3-hydroxyacyl CoA dehydrogenase (LCHAD) in trophoblast cells, analyze the correlation of DNA methylation and gene expression in early-onset preeclampsia (EPE), hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome and antiphospholipid syndrome (APS), to investigate the molecular basis of long-chain fatty acid oxidation changes in different preeclampsia and pathological pregnancy. Methods Primary human cytotrophoblast cells and HTR8/Svneo cells were treated with serum from patients with EPE (14 cases), HELLP (12 cases), APS (14 cases), and normal pregnant women (NP, 14 cases). The methylation level of LCHAD gene promoter region through the MassARRAY platform and mRNA expression level by real-time fluorescent quantitative PCR technique were conducted. Results (1) Cytosine-phosphate-guanine (CpG)sites in human LCHAD DNA promoter region:CpG sites were detected in the range of 558 bp before LCHAD gene transcription start site, the detected CpG sites were 11 sites including 8 single sites and 3 complex sites. The position of these sites were at-984,-960,-899,-853,-811,-796,-774,-727,-615,-595,-579 respectively. (2) The sites of-899,-853,-615 and-595 showed increased methylation level in EPE and HELLP groups. The methylation level at-899,-853 and-615 sites in EPE and HELLP groups were significantly higher than those in NP group(P<0.01). The methylation level at-853 site was higher in EPE group than that in HELLP group(P<0.05). The-595 site showed the unmethylated in EPE, HELLP and APS groups. There were significantly difference between the 3 groups and EPE group(P<0.01). (3) The gene expression of LCHAD mRNA in EPE(0.048±0.005), HELLP(0.045±0.006)and APS(0.044±0.004) groups were significantly lower than NP group(0.076 ± 0.009;P<0.01). (4) The correlation of methylation level and gene expression in all groups: the methylation level at-899,-853,-727,-615 and-579 sites were negatively correlated with gene mRNA expression in EPE group (P<0.05). The methylation level at-899,-853 and-615 sites were negatively correlated with gene mRNA expression in HELLP group(P<0.05). Conclusions The variation of LCHAD DNA methylation of trophoblast cells are found among EPE, HELLP syndrome and APS. The different correlation of LCHAD DNA methylation and gene expression are different in pathological groups. LCHAD DNA methylation of EPE and HELLP syndrome were significantly increased and negatively correlated with LCHAD gene mRNA expression. These results further revealed the molecular basis of long-chain fatty acid oxidation in different preeclampsia and pathological pregnancy.

A series of tetrahydroisoquinoline derivatives were prepared and their peroxisome proliferator-activated receptor (PPAR) alpha/gamma agonistic activities were evaluated to obtain more potent PPAR agonist. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Three compounds exhibited higher agonistic activities of PPARgamma than that of the comparison, six compounds exhibited higher agonistic activities of PPARalpha than that of the comparison, and compound 8a was discovered as a highly potent PPARalpha/gamma agonist that is much more active than that of WY14643 and rosiglitazone. The development of potent PPAR agonists may offer a new choice for the treatment of diabetes.

BACKGROUNDDiffusion weighted imaging (DWI), with the applying of intravoxel incoherent motion model, has showed promising results in obtaining additional information about microperfusion and tubular flow associated with morphologic changes in chronic kidney diseases. The study aims to evaluate the potential of T2-weighted signal intensity (SI) and DWI with mono- and bi-exponential models to reflect the serial changes on cisplatin (CP) induced rat renal fibrosis models.

METHODSMagnetic resonance exams were performed prior to and 2 nd day, 4 th day, 6 th day, 8 th day, 2 nd week, 3 rd week and 4 th week after CP injection at a 3.0T with an animal coil. Besides T2-weighted images (T2WI), DWI of 13 b values from 0 to 1500 s/mm 2 was acquired. Apparent diffusion coefficient (ADC), fluid fraction f, pure diffusivity D and pseudodiffusivity DFNx01 values were calculated. The regions of interest were placed on cortex (CO), outer stripe of the outer medulla (OM) and inner stripe of the outer medulla (OM), parameters were measured and compared among different time points. Five rats were scarified at each time point for pathological examination.

RESULTSOM revealed remarkable hyperintense and broadened before it became an obscure thread, while CO demonstrated moderate hyperintense and IM didn't show significant change on T2WI. On all three stripes, ADC values decreased firstly then kept increasing since the 4 th day; f values decreased on all stripes; D values had a tendency to increase with fluctuations but the changes didn't achieve statistical significance; DFNx01 values increased at the 2 nd day then tended to be steady thereafter. Pathological findings revealed tubules epitheliums swelling followed by inflammation cells infiltration, interstitial fibrosis was observed since the 2 nd week.

CONCLUSIONSAll of T2-weighted SI, ADC, and biexponential models parameters vary during fibrotic process; biexponential model is superior to monoexponential model in separating changes of microperfusion together with tubular flow from pure diffusion.

OBJECTIVETo study the effect and potential mechanism of expression of c-jun N-terminal kinase (JNK) signal pathway on neuron autophagy after diffuse brain injury (DBI).

METHODSMale Sprague Dawley rats (n = 216) were randomly divided into four groups: DBI group (n = 54), SP600125 intervene group (n = 54), DMSO group (n = 54) and sham operation group (n = 54). DBI rat model was established according to the description of Marmarou DBI. At different time points (1, 6, 12, 24, 48 and 72 h) after operation, the histopathologic changes of neurons in cortex were observed by HE staining method; The expression of p-JNK, p-P53, DRAM and Beclin-1 were detected by Western blot and immunohistochemistry.

RESULTSThe results showed that under light microscope degenerated and necrotic neurons were observed to be scattered in cortex at 6 h after operation in DBI group, but these changes were low in SP600125 intervene group. Compared with SP600125 intervene group, the expression of p-JNK in DBI group were enhanced obviously at 6, 12 and 24 h (F = 17.902, P < 0.05); the expression of p-P53 in DBI group were enhanced obviously at 12, 24, 48 and 72 h (F = 7.107, P < 0.05); the expression of DRAM in DBI group were enhanced obviously at 6, 12, 24, 48 and 72 h (F = 15.455, P < 0.05); the expression of Beclin-1 in DBI group were enhanced obviously at 6, 12, 24, 48 and 72 h (F = 11.517, P < 0.05). Compared with DBI group, the expression of p-JNK, p-P53, DRAM and Beclin-1 in DMSO group were similar at 1, 6, 12, 24, 48 and 72 h (F = 1.509, P > 0.05).

CONCLUSIONSThe present results indicate that SP600125 can dramatically improve trauma brain injury from autophagy after DBI and the molecular mechanism is related to the modulation of JNK signal pathway following DBI, while it measures the neuron autophagy by means of intervening JNK signal pathway.

OBJECTIVEThe traditional gracilis musculocutaneous flap is supplied by a branch of deep femoral artery, which enters the muscle in between the upper and middle third of it. So the flap barely reaches the pelvis and perineum region for reconstruction. By exploring the blood supply pattern we tried to rotate the flap Upon at the higher point starting at the obturator foramen in order to let it cover a bigger area.

METHODSanatomical reviewing of the blood supply of the gracilis branches of obturator, medial femoral circumflex and deep femoral arteries. Based on this a new type of longitudinal gracilis musculocutaneous flap supported only by the obturator artery was designed to reach the pelvis, female genitalia, pubic symphysis, inguinal area easily.

RESULTSThe new kind of flap has been applied to 9 patients for deformity repairing and tissue replacement in the pelvic and perineal area. All the flaps survived and achieved satisfactory result with 3 months to 3 years' follow up.

CONCLUSIONSLongitudinal gracilis musculocutaneous flaps supplied by the obturator artery can be used as regular musculocutaneous flap clinically.

OBJECTIVETo investigate the role of autophagy inhibitor chloroquine (CQ) in the proliferation of pulmonary arterial smooth muscle cells (PASMCs) in hypoxia conditions.

METHODSThe following groups in this study were set up: control group, hypoxia group, 50 micromol/L CQ + hypoxia group, 50 micromol/L CQ group. The viability of PASMCs in every group was detected by MTT assay. Autophagic vacuoles in the cells were observed by MDC staining. Protein expression of microtubule associated protein light chain 3 (LC3) was measured by Western blot. Migration of PASMCs was detected by wound healing assay.

RESULTSCompared with control group, no effect on the viability of PASMCs was observed treated by CQ alone. In 1% hypoxia group, cell viability increased significantly compared with that in control group. The number of autophagic vacuoles and the rate of cell migration and also protein expression of LC3-II were also markedly increased. Compared with hypoxia group, addition of CQ increased the number of autophagic vacuoles and the levels of LC3-II protein, but decreased the proliferation and migration of PASMCs.

CONCLUSIONHypoxia could activates autophagy and contributes to proliferation and migration of PASMCs, and autophagy inhibitor CQ could decrease the effect of hypoxia on PASMCs through inhibiting autophagy process.
