Objective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05~0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323~0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.

Objective To investigate the changes of interleukin(IL)-2 and interferon(IFN)-γin serum and synovial fluid of patients with joint injure with Kashin-Beck disease(KBD), and study the roles of IL-2 and IFN-γ in KBD joint injure. Methods In accordance with the "Diagnostic Criteria of Kashin-Beck disease"(GB16003-1995),48 cases of KBD patients and 26 healthy people(control group) from KBD endemic area in Long county Shaanxi province were enrolled in the study. KBD patient were 24 males and 24 females, respectively, aged 40 to 65 years (mean age 51 years). Forty-eight serum specimens and 28 synovial fluid specimens of patients(14 males and 14 females,respectively) were collected. Healthy control group were 13 males and 13 females, respectively. Twenty-six serum specimens of healthy controls were collected. Serum and synovial fluid IL-2 and IFN-γ levels were determined by enzyme-linked immunosorbent assay(ELISA). Results In healthy controls and KBD patients, the midian of serum IL-2 were 46.8 ng/L and 55.7 ng/L, respectively, and IFN-γ were 52.3 ng/L and 48.8 ng/L, respectively. The difference was not statistically significant between healthy controls and KBD patients(t = 0.62, 0.70, all P > 0.05).In synovial fluid of KBD patient, the midian of IL-2 and IFN-γwere 48.3 ng/L and 44.1 ng/L, respectively. The difference was not statistically significant between serum and synovial fluid in KBD patients(t = 0.69, 1.72, all P >0.05). Conclusion Serum and synovial fluid IL-2 and IFN-γare not significantly increased in KBD patients with articular damage, indicating that IL-2 and IFN-γare not involved in KBD joint injury.

Objective To explore the characteristics of proinsulin secretion in latent autoimmune diabetes in adults (LADA). Methods Fasting and 2 h sera in oral glucose tolerance test from 36 LADA patients, 37 type 2 diabetic patients and 43 healthy controls were collected to test glucose, proinsulin (PI) and C-peptide (CP) by radioimmune assay. Glutamie acid decarboxylase antibodies (GAD-Ab) were determined by radioligand assay.Results (1) Fasting proinsulin (FPI) and 2 h proinsulin (PPI) level in LADA patients were lower than those in type 2 diabetic patients (P<0.05), being both significantly inereasad compared with healthy controls (P<0.05 or P<0.01); The ratios of FPI/FCP and PPI/PCP (%) in LADA were beth significantly higer than those of type 2 diabetes mellitus and controls (P<0.05 or P<0.01); (2) LADA type-1 (GAD-Abe>0.3) patients showed lower PI levels(P<0.05 or P<0.01) and higher PI/CP ratio (all P<0.05) than LADA type-2 (0.05≤GAD-Ab<0.3); Meanwhile, there were no significant differences in above parameters between LADA type-2 and type 2 diabetes meUitus (P>0.05). (3) GAD-Ab index was negatively correlated with FPI and PPI in LADA group (r=-0.236 and-0.268, both P<0.05), and positively correlated with PPI/PCP (r=0.254, P=0.030).Meanwhile BMI was positively correlated with FPI, PPI and PI/CP in type 2 diabetes mellitus (all P<0.01). No factor entered the multiple regression analysis for predieting the hyperproinsulinemia and dispropriately elevated proinsulin levels in LADA patients. (4) According to the 99.5 th percentile of proinsulinemia in the healthy controls, which is defined as the cutoff point dispropriately elevated proinsulin levels, the proportion of subjects with fasting dispropriately elevated proinsulin levels (FPI/FCP) were 77.8%, 62.2% and 2.3% in LADA, type 2 diabetes meUitus and controls respectively, and PPI/PCP 83.3%, 51.4% and 2.3% respectively. Conclusion LADA patients, as well as type 2 diabetic patients, all showed hyperproinsulinemia and disproportionately elevated proiasulin levels that were one of characteristics of defective β-cell function. Moreover, disproportionately elevated nproinsulin level is more evident in LADA patients than that in type 2 diabetics and this may be related to humoral immunity.

OBJECTIVETo compare the therapeutic effect of Astragalus and Angelica Mixture (AAM) on treating CKD patients according to different CKD primary diseases, staging and TCM syndromes.
METHODSA multicentre, open-label, and self control clinical design was used, and thirty-two patients in line with inclusive criteria were recruited. Based on maintaining their previous basic CKD treatment, patients additionally took AAM (Astragalus and Angelica each 30 g), once a day, three months consisted of one therapeutic course. Serum creatinine (SCr), estimated glomerular filtration rate (eG- FR), 24 h urinary total protein (UTP), plasma albumin (ALB), hemoglobin (Hb), and changes of TCM syndrome factor integrals were compared before treatment, at the end of month 1, 2, and 3. The differences in the aforesaid indices were compared between CKD patients with different CKD primary diseases (chronic glomerulonephritis, chronic renal tubulointerstitial disease, hypertensive renal damage), different CKD stages (CKD 3 and CKD 4), and patients of qi-blood deficiency syndrome (QBDS) and non-QBDS.
RESULTSAAM could improve 78.12% (25/32) patients' renal function. Compared with before treatment, SCr decreased (12.08% +/- 10.11%), eGFR increased (21.14% +/- 18.55%), and ALB increased (2.76% +/- 1.97%) at the end of 3-month treatment (all P < 0.05). As for TCM syndrome factor integrals, compared with before treatment, the integrals for qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome decreased, while the integrals for dampness heat syndrome and turbid-toxin syndrome increased (all P < 0.05). There was no obvious difference in all indices except the integral for hypertensive renal damage patients of yin deficiency syndrome (P > 0.05). The SCr decreasing percent was 19.82% +/- 8.30% for patients of non-QBDS and 5.24% +/- 10.75% for patients of QBDS. The latter was higher with statistical difference (P < 0.05). As for TCM syndrome factor integrals, the integral differences of qi deficiency and blood deficiency were obviously higher in patients of QBDS, when compared with patients of non-QBDS (P < 0.05).
CONCLUSIONAAM could improve the renal function of CKD patients, elevate their ALB levels, and ameliorate associated qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome, especially for CKD patients of QBDS.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and metabolic syndrome (MS) in patients with impaired glucose tolerance (IGT).Methods:A total of 415 patients with abnormal glucose tolerance were screened by oral glucose tolerance test in Changsha Traditional Chinese Medicine Hospital (Changsha Eighth Hospital) from October 2015 to September 2019. General data were collected and blood routine and biochemical indexes were detected. There were 193 cases in the observation group and 222 cases in the control group. The RDW and other clinical indicators were compared between the two groups, the correlation between RDW and other indicators was analyzed, and the risk factors of metabolic syndrome were analyzed.Results:⑴ The RDW, systolic blood pressure (SBP), diastolic blood pressure (DBP), height (Ht), weight (Wt), waist circumferenc (Wc), triglyceride (TG), cholesterol (CHOL), low density lipoprotein (LDL), creatinine (Cr), uric acid (UA), alanine aminotransferase (ALT), high sensitive C-reactive protein (hs-CRP), body mass index (BMI) of the observation group were significantly higher than those of the control group, while the high density lipoprotein (HDL) was significantly lower than that of the control group, with statistically significant difference ( P<0.05); ⑵ correlation analysis showed that RDW was positively correlated with SBP, DBP, Ht, Wt, Wc, TG, CHOL, Cr, UA, ALT, hs-CRP, BMI, and negatively correlated with HDL ( P<0.05); ⑶ binary logistic regression analysis showed that RDW, Wt, Wc, CHOL, HDL, LDL and hs-CRP were independent risk factors for MS in patients with impaired glucose tolerance. Conclusions:The increase of RDW is a predictor of metabolic syndrome in people with abnormal glucose tolerance, which may provide some reference value for the prevention and treatment of metabolic syndrome.

OBJECTIVETo evaluate the effect of white rot fungus Phanerochaete chrysosporium on removal of gaseous chlorobenzene.
METHODSFungal mycelium mixed with a liquid medium was placed into airtight bottles. A certain amount of chlorobenzene was injected into the headspace of the bottles under different conditions. At a certain interval, the concentrations in the headspace were analyzed to evaluate the degradation of chlorobenzene by P. chrysosporium.
RESULTSThe degradation effects of P. chrysosporium on chlorobenzene under different conditions were investigated. The difference in the optimum temperature for the growth of the fungi and chlorobenzene degradation was observed. The data indicated that a lower temperature (28 degrees C) would promote the degradation of chlorobenzene than the optimum temperature for the growth of the fungi (37 degrees C). A low nitrogen source concentration (30 mg N/L) had a better effect on degrading chlorobenzene than a high nitrogen source concentration (higher than 100 mg N/L). A high initial concentration (over 1100 mg/m3) of chlorobenzene showed an inhibiting effect on degradation by P. chrysosporium. A maximum removal efficiency of 95% was achieved at the initial concentration of 550 mg/m3.
CONCLUSIONP. chrysosporium has a rather good ability to remove gaseous chlorobenzene. A low nitrogen source concentration and a low temperature promote the removal of chlorobenzene by P. chrysosporium. However, a high initial chlorobenzene concentration can inhibit chlorobenzene degradation.
