Objective To study the effects of Xianlingqianggukoufuye (XLQGKFY) on postmenopausal osteoporosis in ovariectomized female rats. Method 60 female Sprague-dawley rats in 7-month were used, 50 of them were ovariectomized and randomly divided into 5 groups:ovariectomized (OVX), OVX+ Nylestriol, OVX+XLQGKFY (high dose, middle dose, low dose), the others were sham-operated group. Rats were treated with drugs starting at 3rd day after the operation for 90 days. Double in vivo fluorochrome labeling was administered to all rats. At the end-point of study, the blood was collected to detecte contents of ALP, StrACP in serum, the fourth lumar vertebra (LV4) and femur bone sections were cut and stained for bone histomorphometric analyses, biomechanical analyses and BMP analyses. Result XLQGKFY decreased greatly the StrACP content, increased bone stiffness, bone M-load, improved bone biomechanical property. Conclusion XLQGKFY has a good preventive effect on postmenopausal osteoporosis which provides for clinical use.

Objective:To study the clinicopathologic features of IgG4-related pulmonary inflammatory pseudotumor (IRPIP), and its correlations with CD4+T lymphocytes and interleukin-10 (IL-10) expression,and to investigate the immunopathological factors in the disease of IgG4-related pulmonary inflammatory pseudotumor .Methods: Expressions of IL-10, CD3, CD20, CD4, CD8 were examined by immunohistochemistry in 17 cases of IgG4-related pulmonary inflammatory pseudotumor tissues and 15 cases of IgG4-nonrelated pulmonary inflammatory pseudotumor tissues ( INPIP) .To analyze the differences of these indexes expression between IRPIP and INPIP.Results: In group of IRPIP, the CD4+T lymphocytes number and the ratio of CD 4+T lymphocytes number/CD8+T lymphocytes number were all apparently higher than those in the group of INPIP (P=0.006,0.023,respectively).The cells numbers of CD3,CD8,IL-10 positive expression in IRPIP were higer than those in INPIP ,and the cells number of CD20 positive expression in IRPIP was lower than that in INPIP,but these differences all had no statistical significance (P>0.05).In IRPIP,the number of IgG4+plasmacytes was positively related to the number of IL-10+cell (r=0.517),the correlation had statistical significance (P=0.033). Conclusion:The number of CD4+T lymphocytes increased in addition to the increased number of IgG 4+plasmacytes in the lesion back-ground of IRPIP,and the number of IgG4+plasmacytes was positively related to the number of IL-10+cells.It is suggested that the increased number of Th 2 lymphocyte and the increased secretion of cytokine IL-10were are immunopathological factors participated in the disease of IRPIP .

Toimprovethesensitivity,aCuOnanoparticledopedinmolecularlyimprintedpolymer(MIP)film for the determination of phenobarbital was prepared by using methacrylic acid as functional monomers, ethylene glycol maleic rosinate acrylate as a cross linking agent by thermal polymerization method. The electrochemical properties of the nano-doped sensor were investigated using cyclic voltammetry ( CV ) , differential pulse voltammetry ( DPV ) , electrochemical impedance spectroscopy ( EIS ) and chrono-amperometry ( CA) . The chemical structures and morphologies of the imprinted films were characterized using Fourier transform infrared spectroscopy and scanning electron microscopy. The results indicated that the sensors response value of peak current showed a linear dependence on the phenobarbital concentration in the ranges of 1. 2 × 10-7-1. 5 × 10-4 mol/L of phenobarbital. ( Linear regression coefficient=0. 9984 ) with the detection limit ( S/N=3 ) of 8. 2 × 10-9 mmol/L. The prepared sensor was successfully applied to the determination of phenobarbital in practical samples with recovery ranging from 96 . 5% to 103 . 0%.

Objective To study the expressions of hypoxia inducible factor (HIF)-1 and angiopoietin (Ang)-2 in repeated gastrointestinal bleeding due to vascular malformation, and the efficacy of treatment with thalidomide. Methods Twenty-five patients with repeated gastrointestinal bleeding due to vascular malformation confirmed by capsule endoscopy or enteroscopy were collected and 18 subjects without severe diseases were served as controls. Ten patients with gastrointestinal vascular malformation, who received 25 mg of thalidomide 4 times daily for 4 months and were followed up for at least one year, were also enrolled. The serum samples from all participauts were detected for expressions of HIF-1 and Ang-2 using enzyme-linked immunosorbent assay (ELISA).The expressions of HIF-1 and Ang-2 were compared between angiodysplasia group and control group.The expressions of HIF-1 and Ang-2 were comparatively evaluated before and after treatment with thalidomide in treatment group. Results The expressions of HIF-1 and Ang-2 in vascular malformation group [( 113. 84 ± 26. 66 ) ng/ml and ( 652. 11 ± 140. 39) ng/ml, respectively] were significantly higher than that of control group [(43.28±17.30) ng/ml and (265.60±53.88) ng/ml,respectively, P=0. 000]. The expression of HIF-1 was positively associated with that of Ang-2. (r=0. 700, P= 0. 000). There was no difference in expressions of HIF-1 and Ang-2 before and after treatment with thalidomide (P=0. 498 and =0. 136, respectively). However, significant reduction of Ang-2 [(113. 80±73. 60) ng/ml(P=0. 003)] was found in 8 effectively treated patients after thalidomide treatment. Conclusions HIF-1 and Ang-2 might play an important role in the formation of vascular malformation. The extent of Ang-2 reduction after thalidomide treatment may be helpful in evaluating its efficacy or prognosis.

Objective To explore the clinical outcomes of different mild-stimulation in poor ovarian responders in vitro culture/intracytoplasmic injection (IVF/ICSI) to provide the evidence for clinical treatment,and investigate clinical parameters including pre-ovulation rate,rate of oocytes retrieved,fertilization rate,good quality embryo rate,and pregnancy rate per cycle.Methods The clinical date of a total 180 IVF cycles of infertile patients undergone from Jan 2013 to May 2016 in medical reprodution center of Xiang Tan Central Hospital.According to the different methods of controlled ovarian hyperstimulation (COH),the cycles were divided into 3 groups:group A with 60 cycles of early five days using clomiphene,group B with 60 cycles of persistent using clomiphene,and group C with 60 cycles using artificial luteal-phase ovarian stimulation protocol.Results The basic situations in three groups were no significant difference (P ＞0.05).Compared to groups B and C,the pre-ovalution rate was more in group A (P ＜ O.05),and the rate of oocytes retrieved,fertilization rate,good quality embryo rate,and preganacy rate per cycle were higher in groups B and C (P ＜ 0.05).The rate of oocytes retrieved,fertilization rate,good quality embryo rate,and preganacy rate per cycle were no significant difference among gourps B and C.The good quality embryo rate and preganacy rate per cycle in groups B and C were higher than group A,and group B was higher than group A (P ＜ 0.05).Conclusions Persistent using clomiphene or persistent using clomiphene in COH could decrease the rate of pre-ovalution,and get more rate of oocytes retrieved,good quality embryo rate,and preganacy rate per cycle.

Objective To investigate the clinical value of C-reactive protein (CRP) combined with prothrombin time (PT) and partially activated thromboplastin time (APTY) in the diagnosis of neonatal late-onset sepsis.Methods From January 2013 to January 2018,100 neonates with sepsis admitted to our department of neonatology in Lishui Maternal and Child Health-Care Center were collected.According to the results of blood culture,neonates with positive blood culture were classified as sepsis group A (53 cases),and neonates with negative blood culture were classified as sepsis group B (47 cases).Another 50 normal newborns born at the same period were included in the control group.The CRP,PT and APTT values of the three groups were detected and compared.The receiver-operating characteristic curves (ROC) were plotted to obtain the area under ROC curve (AUC) and the sensitivity,specificity,positive predictive value and negative predictive value.Another ROC curve was plotted to obtain the area under ROC curve (AUC) and the sensitivity,specificity,positive predictive value,and negative predictive value for a new variable,CPR + PT + APTT,which was established using a binomial logistic regression method.Results The results of CPR,PT and APTT in the control group,sepsis group A and sepsis group B all increased in turn (F=10.616,6.155,5.243,P =0.000,0.000,0.000).CPR + PT + APTT had the largest AUC (0.94),the highest sensitivity (93.42％),the highest specificity (91.66％),the highest positive predictive value (92.60％),and the highest negative predictive value (78.55％) in the four indicators.Conclusion When blood culture fails to diagnose late-onset neonatal sepsis,combined detection of CPR + PT + APTT can provide some clues for its early diagnosis,which is worthy of clinical attention.

Objective: To investigate the clinical features, immunohistochemical and differential diagnosis of desmoplastic fibroblastoma. Methods: The clinical data and pathology features of 7 cases of desmoplastic fibroblastoma were collected and immunohistochemical study were carried out in all cases with a review of the literatures. Results: There were 2 males and 5 females, with age ranging from 31 to 71 years (average and mean age were 59 and 61 years, respectively). The tumors were located in extremities and abdomen (left toe and right toe, right foot back, left leg and right thigh, right forearm and left hepatic lobe). Clinically, the tumors presented as slow growing painless masses of long standing duration. Grossly, the tumors were well-circumscribed with firm, white to gray cut-off surface. Tumor size ranged from 1.2 to 4.0 cm in maximum diameter (average 3.0 cm). Microscopically, 2 cases were located in dermis, 4 cases were located in subcutaneous and 1 case was located in liver parenchyma. It was composed of spindle-shaped or stellate cells with a fibroblastic or myofibroblastic appearance, and sparsely scattered in densely fibrous or fibromyxoid background. There was small vascular component in tumor background. At high magnification, the tumor cells were medium size with abundant cytoplasm, and the nucleus were small and always with small nucleoli. In some cases, the tumor cells were slightly larger with enlarged nuclei, but without cellular atypical and mitosis. Immunohistochemical study showed that the tumor cells were strongly positive for vimentin, desmin, S-100 protein and CD34, but CKpan was negative. α-SMA showed focal positive in one case. Ki-67 index ranged from 1% to 2%. Four cases were followed-up (ranged from 11 to 21 months, average 16.5 months) and the patients had no recurrence after surgery. Conclusions Desmoplastic firoblastoma is a rare soft benign tumor. The differential diagnosis includes other benign or low-grade fibroblastic/myofibroblastic lesions.

OBJECTIVETo assess the association of short tandem repeats (STRs) loci with aggressive behaviors of schizophrenia.

METHODSBlood samples from 123 schizophrenic patients with aggressive behaviors and 489 schizophrenic patients without aggressive behaviors were collected. DNA from all samples was amplified with a PowerPlex 21 system and separated by electrophoresis to determine the genotypes and allelic frequencies of 20 STR loci including D3S1368, D1S1656, D6S1043, D13S317, Penta E, D16S639, D18S51, D2S1338, CSF1PO, Penta D, TH01, vWA, D21S11, D7S820, D5S818, TPOX, D8S1179, D12S391, D19S433, and FGA.

RESULTSAll of the 20 STR loci have reached Hardy-Weinberg equilibrium in both groups. A significant difference was found in allelic and genotypic frequencies of loci Penta D between the two groups (alleles: P=0.042; genotypes: P=0.014) but not for the remaining 19 loci (P> 0.05). Univariate analysis also showed a significant difference for allele 10 and genotypes 10-12 of Penta D between the two groups (P=0.0027, P=0.0001), with the OR being 1.81 (95%CI: 1.22-2.67) and 4.33 (95%CI: 1.95-9.59), respectively.

CONCLUSIONPenta D may be associated with aggressive behaviors of schizophrenia. Allele 10 and genotypes 10-12 of Penta D may confer a risk for the disease.

OBJECTIVETo study the clinicopathological characteristics of hepatic angiomyolipoma (HAML) and to evaluate the correlation between clinicopathological parameters and tumor subtypes.

METHODSRetrospective analysis of clinicopathological features was conducted in 182 cases of HAML.

RESULTSHAML patients were predominantly female (M:F=1:4) and most commonly presented with non-specific symptoms. The median age at diagnosis was 46 years, ranged from 17 to 77 years. Tumor diameter was ranged from 0.3 to 32.0 cm with an average of 5.0 cm. Majority of the tumor was epithelioid type (112/165, 67.9%). Extramedullary hematopoiesis, multinucleated giant cells, intranuclear inclusions, nucleolus, cellular atypia, invasive growth pattern, multiple masses, hyperpigmentation and purpura-like changes mostly occurred in the epithelioid type (P<0.05). Extramedullary hematopoiesis was commonly seen in HAML, the significance of which was still uncertain.

CONCLUSIONSMost of HAML are epithelioid type, characterized by a proliferation of predominantly epithelioid cells, in which extramedullary hematopoiesis is commonly seen. Some morphologic features that may predict malignant such as necrosis, mitotic figures, and tumor emboli are only found in the epithelioid HAML. Mitotic activity, tumor necrosis, tumor thrombus, giant cells, periportal invasion, multiple lesions and tumors size over 10 cm are closely related with tumor recurrence and metastasis.
