Serum enzymes that play potential roles in tumor growth have recently been reported to have prognostic relevance in a diverse array of tumors. However, prognosis-related serum enzymes are rarely reported for nasopharyngeal carcinoma(NPC). To clarify whether the level of serum enzymes is linked to the prognosis of NPC, we reviewed the pretreatment data of lactate dehydrogenase(LDH), alkaline phosphatase (ALP), and glutamyl transferase (GGT) in 533 newly diagnosed NPC patients who underwent radical radiotherapy between May 2002 and October 2003 at Sun Yat-sen University Cancer Center. Patients were grouped according to the upper limit of normal values of LDH, ALP, and GGT. The Kaplan-Meier method and log-rank test were used for selecting prognostic factors from clinical characteristics and serum enzymes, and the chi-square test was applied to analyze the relationships of clinical characteristics and serum enzymes. Finally, a Cox proportional hazards model was used to identify the independent prognostic factors. We found that increased levels of LDH had poor effects on both overall survival and distant metastasis-free survival (P = 0.009 and 0.035, respectively), and increased pretreatment level of serum ALP had poor effects on both overall survival and local recurrence-free survival (P = 0.037 and 0.039, respectively). In multivariate analysis, increased LDH level was identified as an independent prognostic factor for overall survival. Therefore, we conclude that increased pretreatment serum LDH and ALP levels are poor prognostic factors for NPC.

OBJECTIVETo study the association of single nucleotide polymorphisms (SNPs) of transcription factors (NKX2.5, GATA4, TBX5, and FOG2) with congenital heart disease (CHD) in the Chinese population.

METHODSPubMed, Google Scholar, CNKI, Wanfang Data, and Weipu Data were searched for articles on the association of SNPs of target genes with CHD in the Chinese population. If one locus was mentioned in at least two articles, the random or fixed effect model was used to perform a pooled analysis of study results and to calculate the pooled OR and its 95%CI. If a locus was mentioned in only one article, related data were extracted from this article to analyze the association between the SNPs of this locus and CHD.

RESULTSTwenty-three articles were included. The Meta analysis showed that there were significant differences between the CHD and control groups in the genotype and allele frequencies of GATA4 rs1139244 and rs867858 and the genotype frequency of GATA4 rs904018, while there were no significant differences in the SNPs of the other genetic loci between the two groups. The single-article analysis showed that there were significant differences between the two groups in the allele frequencies of NKX2.5 rs118026695/rs703752, GATA4 rs884662/rs12825/rs12458/rs3203358/rs4841588, and TBX5 rs6489956. There were no significant differences in the SNPs of FOG2 locus between the two groups.

CONCLUSIONSThe SNPs of some loci in NKX2.5, GATA4, and TBX5 are associated with CHD in the Chinese population, but the association between the SNPs of FOG2 locus and the development of CHD has not been found yet.

Objective There are few studies on whether progesterone has neuroprotective effects on cerebral hemorrhage. This study aimed to observe the effects of different doses of progesterone on Matrix metalloproteinase-9（MMP-9）and Nuclear factor-κB （NF-κB）in cerebral hemorrhage in male rats, and to explore the neuroprotective effects and possible mechanism of progesterone on cerebral hemorrhage in rats. Methods We randomly divided 174 adult male rats into six groups of equal number with random number table. The models of cerebral hemorrhage were established. The low-, medium- and high-dose progesterone groups were administered with progesterone 4, 8, 16 mg/kg, respectively. The rats in the sham operation and model groups were given same volume of normal saline. We detected the expression of MMP-9 and NF-κB in the brain tissue of each group by Western blotting at 3 days. Moreover, we used the other rats to obtain the neurological severity scores（NSS），and measure the water content of brain tissue. Furthermore, we detected the expressions of MMP-9 and NF-κB by immunohistochemistry at 1, 3 and 7 days. Results The low-, medium- and high-dose progesterone groups could all improve the neurological function of rats after cerebral hemorrhage, and the middle dose group showed the best effects（P<0.05）. Moreover, the low-, medium- and high-dose progesterone groups can reduce the expression of MMP-9 and NF-κB, and the middle dose group also indicated the best effects （P<0.05）. Conclusion Progesterone might improve the neurological function and reduce edema in rats after cerebral hemorrhage, which may be related to the decrease of MMP-9 and NF-κB expression.

To explore the effect of vinegar-processed Curcumae Rhizoma on endogenous metabolites in bile by investigating the endogenous metabolites difference in bile before and after Curcumae Rhizoma was processed with vinegar. Alcohol extracts of crude and vinegar-processed Curcumae Rhizoma, as well as normal saline were prepared respectively, which were then given to the rats by intragastric administration for 0.5 h. Then common bile duct intubation drainage was conducted to collect 12 h bile of the rats. UPLC-TOF-MS analysis of bile samples was applied after 1∶3 acetonitrile protein precipitation; unidimensional statistics were combined with multivariate statistics and PeakView software was compared with network database to identify the potential biomarkers. Vinegar-processed Curcumae Rhizoma extracts had significant effects on metabolites spectrum in bile of the rats. With the boundaries of P<0.05, 13 metabolites with significant differences were found in bile of crude and vinegar-processed Curcumae Rhizoma groups, and 8 of them were identified when considering the network database. T-test unidimensional statistical analysis was applied between administration groups and blank group to obtain 7 metabolites with significant differences and identify them as potential biomarkers. 6 of the potential biomarkers were up-regulated in vinegar-processed group, which were related to the metabolism regulation of phospholipid metabolism, fat metabolism, bile acid metabolism, and N-acylethanolamine hydrolysis reaction balance, indicating the mechanism of vinegar-processed Curcumae Rhizoma on endogenous metabolites in bile of the rats.

Aging is a gradual process during the loss of functions in cells,organs and tissues by time. The molecular mechanisms of aging-related theories include the classical ones such as telomere,oxygen radical and nonenzymatic glycosylation,as well as the newly proposed ones such as DNA methylation,mitochondrial DNA （mtDNA）and autophagy. The latest study showed the anti-aging effect of autophagy in hematopoietic stem cells. In recent years,based on the molecular regulative mechanisms of aging,a number of the promising anti-aging drugs have been found,including nicotinamide mononucleotide（NMN）and FOXO4-DRI,a peptide of anti-aging. In addition,there are many new discoveries in the field of plant extracts,in which,the extracts from Chinese herbal medicine（CHM）,some single CHMs and the classical prescriptions of CHM,represented by curcumin and resveratrol,have the partial anti-aging effects by regulating the molecular mechanisms of aging both in vivo and in vitro. In brief,developing or exploring anti-aging drugs,especially the natural drugs,is one of the main development directions in the field of anti-aging research in the basis of the molecular regulative mechanisms of aging.

Although the development of the 2009 SpA classification criteria by Assessment of SpondyloArthritis international Society (ASAS) represents an important step towards a better definition of the early disease stage particularly in axial spondyloarthritis (axSpA), the specificity of the criteria has been criticized these days. As the commonest zoonotic infection worldwide, human brucellosis can mimic a large number of diseases, including SpA. This study was performed to determine the frequency of rheumatologic manifestations in patients with brucellosis and the chance of misdiagnosing them as having axSpA in central China. The results showed that clinical manifestations of axSpA could be observed in brucellosis. Over half of patients had back pain, and one fifth of the patients with back pain were less than 45 years old at onset and had the symptom for more than 3 months. Two young males were falsely classified as suffering from axSpA according to the ASAS criteria, and one with MRI proved sacroiliitis was once given Etanercept for treatment. Therefore, differential diagnosis including human brucellosis should always be kept in mind when applying the ASAS criteria, even in traditionally non-endemic areas.

This study explored the in vivo effects and mechanisms of the modern classical prescription Supplemented Gegen Qinlian Decoction Formula(SGDF) against diabetic kidney disease(DKD). Sixty rats were randomly divided into the normal group, model group, SGDF group, and rosiglitazone(ROS) group. The modified DKD rat model was established by employing the following three methods: exposure to high-fat diet, unilateral nephrectomy, and intraperitoneal injection of streptozotocin(STZ). After modeling, rats in the four groups were treated with double distilled water, SGDF suspension, and ROS suspension, respectively, by gavage every day. At the end of the 6 th week of drug administration, all the rats were sacrificed for collecting urine, blood, and kidney tissue, followed by the examination of rat general conditions, urine and blood biochemical indicators, glomerulosclerosis-related indicators, podocyte pyroptosis markers, insulin resistance(IR)-related indicators, and key molecules in the insulin receptor substrate(IRS) 1/phosphatidylinositol-3-kinase(PI3 K)/serine threonine kinase(Akt) signaling pathway. The results showed that SGDF and ROS improved the general conditions, some renal function indicators and glomerulosclerosis of DKD model rats without affecting the blood glucose(BG). Besides, they ameliorated the expression characteristics and levels of podocyte pyroptosis markers, alleviated IR, and up-regulated the protein expression levels of the key molecules in IRS1/PI3 K/Akt pathway to varying degrees. In conclusion, similar to ROS, SGDF relieves DKD by targeting multiple targets in vivo. Specifically, it exerts the therapeutic effects by alleviating podocyte pyroptosis and IR. This study has preliminarily provided the pharmacological evidence for the research and development of new drugs for the treatment of DKD based on SGDF.

To explore the effect and mechanism of Dahuang Zhechong Pills(DHZCP), a classical prescription, in improving testicular aging(TA) in vivo, the authors randomly divided 24 male rats into four groups: the normal, model, DHZCP and vitamin E(VE) groups. The TA rat model was established by continuous gavage of D-galactose(D-gal). During the experiment, the rats in the DHZCP and VE groups were given DHZCP suspension and VE suspension, respectively by gavage, while those in the normal and model groups were gavaged saline separately every day. After the co-administration of D-gal and various drugs for 60 days, all rats were sacrificed, and their blood and testis were collected. Further, various indexes related to TA and necroptosis of testicular cells in the model rats were examined and investigated, which included the aging phenotype, total testicular weight, testicular index, histopathological features of testis, number of spermatogenic cells, sex hormone level, expression characteristics of reactive oxygen species(ROS) in testis, expression levels and characteristics of cyclins in testis, and protein expression levels of the key molecules in receptor-interacting serine/threonine-protein kinase 1(RIPK1)/receptor-interacting serine/threonine-protein kinase 3(RIPK3)/mixed lineage kinase domain like pseudokinase(MLKL) signaling pathway in each group. The results showed that, for the TA model rats, both DHZCP and VE improved their aging phenotype, total testicular weight, testicular index, pathological features of testis, number of spermatogenic cells, serum testosterone and follicle stimulating hormone levels, expression characteristics of ROS and protein expression levels and characteristics of P21 and P53 in testis. In addition, DHZCP and VE improved the protein expression levels of the key molecules in RIPK1/RIPK3/MLKL signaling pathway in testis of the model rats. Specifically, DHZCP was better than VE in the improvement of RIPK3. In conclusion, in this study, the authors found that DHZCP, similar to VE, ameliorated D-gal-induced TA in model rats in vivo, and its mechanism was related to reducing necroptosis of testicular cells by inhibiting the activation of RIPK1/RIPK3/MLKL signaling pathway. This study provided preliminary pharmacological evidence for the development and application of classical prescriptions in the field of men's health.

To observe the multi-targeted therapeutic effects of Huangkui Capsules(HKC)on insulin resistance(IR)and urine microalbumin in the early diabetic kidney disease(DKD)patients. The case data from the 83 DKD patients at G2 and A2 stage were collected respectively and analyzed retrospectively. According to the different treatment,all patients were divided into the control(A)group(40 cases)and the treated(B)group(43 cases). Among them,the A group patients were received "routine basic treatment";the B group patients were received "routine basic treatment+HKC". For the 2 group patients,firstly,the baseline parameters before receiving the treatment were compared respectively,and then,the changes of the total scores of traditional Chinese medicine(TCM) syndromes and the indicators of IR,urine protein,renal function,blood lipids and safety after receiving the treatment for 8 weeks were compared,respectively. Furthermore,for the all patients,the correlation analysis between IR and urine protein or IR and the total scores of TCM syndromes was carried out,respectively. The results showed that,for the B group patients received "routine basic treatment",their total scores of TCM syndromes,urine protein indicators including urine microalbumin(micro-UAlb) and urine microalbumin/urinary creatinine(UACR),IR indicators including fasting serum insulin(FIN)and homeostasis model assessment of insulin resistance(HOMA-IR)were significantly improved,respectively. For the all DKD patients,before and after the treatment,the main IR indicators(FIN and HOMA-IR)were positively correlated with urine protein indicators(micro-UAlb and UACR). The main IR indicators(FIN and HOMA-IR) were also positively correlated with the total scores of TCM syndromes. In addition,2 treatments had no significant effects on renal function,blood lipids and safety indicators in the all DKD patients. Overall, "routine basic treatment+HKC" can ameliorate IR and reduce urine microalbumin in the early DKD patients. Its therapeutic targets may be not only proteinuria,but also IR,which is the upstream risk factor of proteinuria.
