ObjectiveTo investigate the efficacy of highly active antiretroviral therapy (HAART) for HIV/HCV co-infection patients. MethodsA randomized and double blinded trial was conducted in sixty-three HIV/HCV co-infected patients ( group A) and 62 HIV infected patients ( group B). The group A (study group) was further divided into A1, A2, A3 subgroups randomly by Spw-Pb network data system, and were given three different HAART regimens based on nevirapine (NVP), efavirenz (EFV) and lopinavir/ritonavir(LPV/r), respectively. CD4+ T lymphocyte counts, HIV virus load, glutamate-pyruvate transaminase (ALT) were detected at baseline and at the endpoint of study (48 weeks). SPSS 13.0 was used for statistical analysis. One-way ANOVA and LSD-t tests were performed. ResultsAfter 48 weeks treatment, HIV RNA became negative in 59 patients of group A (59/63, 93.7％ ), while that in group B was 61 (61/62, 98.4％ ) (x2 =0. 159, P ＞ 0.05 ). CD4+ T lymphocyte count in group A was (208 ± 77 )/μL, which was significantly lower than that in group B (263 ± 78)/μL (t =-2. 759, P = 0. 008 ).ALT level in group A was (57 ±49)U/L, which was significantly higher than in group B (31 ± 14) U/L (t = 2. 027, P = 0.047). CD4 + T lymphocyte count in group A3 was significantly higher than that in A1 (t=-2. 191, P =0.045), while ALT level in A1 was much higher than that in subgroups A2 and A3 ( t = 2.568 and 2.478, P ＜ 0. 05 ). The incurrence of drug-induced hepatitis in HIV/HCV co-infected group was much higher than that in HIV infected group (55.5％ vs. 27.4％, x2 = 10. 182, P = 0.001 ).ConclusionsHCV co-infection in HIV patients shows no impact on virological response to HAART, but the immunological response is poorer.Hepatotoxicity is common among patients receiving HAART, especially those who are receiving NVP containing regimens. LPV/r based regimens are recommend for HIV/HCV coinfected patients.

Objective There are few studies on the application of low molecular weight heparin (LMWH) in the therapy of women with recurrent spontaneous abortion (RSA) pregnant by assisted reproductive technology (ART).The article aimed to explore the clinical research of LMWH in therapy of women with RSA pregnant by ART.Methods 126 women with RSA pregnant by ART were enrolled and they were diagnosed and treated in Reproductive Medicine Center in the Affiliated Hospital of Guangdong Medical University from January 2010 to February 2016.According to the patient′s agreement on LMWH treatment, 60 patients in agreement with LMWH treatment were divided into 2 groups: LMWH+IUI group(n=30) and LMWH+ IVF-ET group(n=30).66 patients in disagreement with LMWH treatment were also divided into 2 groups: IUI group(n=32) and IVF-ET group(n=34).Comparison was made in patients from 4 groups concerning pregnancy success rate, live birth rate, pregnancy time involving RSA and incidence of pregnancy complications.At the same time, the occurrence of adverse reactions during the use of LMWH was also observed.Results The pregnancy time involving RSA in LMWH+IUI group significantly increased compared with IUI group([82.67±9.10]d vs [48.17±8.68]d)(P<0.05).The pregnancy success rate and live birth rate in LMWH+ IVF-ET group were both higher than those of IVF-ET group (66.7% vs 35.29%, 85.00% vs 50.00%)(P<0.05) and significant difference was also found in the incidence of RSA, the pregnancy time involving RSA, and the morbidity of gestational hypertension between groups(P<0.05).The results of D2D at 4 weeks of pregnancy in LMWH+IUI group([0.65±0.07]mg/L) and LMWH+ IVF-ET group([0.625±0.06]mg/L) were lower than those of LMWH group ([0.76±0.12]mg/L) and LMWH group([0.77±0.06]mg/L).The result of D2D at 6 weeks of pregnancy in LMWH+IUI group was lower than those of IUI group and IVF-ET group, and D2D in LMWH+ IVF-ET group was lower compared with IVF-ET group(P<0.05).The results of D2D in all the four groups increased with the pregnancy weeks(P<0.05).The prothrombin time(PT) at 4 weeks of pregnancy in LMWH+IUI group, IUI group and LMWH+ IVF-ET group ([12.53±0.38]s, [12.38±0.65]s, [12.47±0.58]s) was significantly higher at pre-pregnancy([12.33±0.52]s, [12.30±0.68]s, [12.22±0.64]s) and 6 weeks of pregnancy([12.13±0.62]s, [12.05±0.60]s, [12.03±0.54]s) (P<0.05).Among 60 cases treated with LMWH, small area ecchymoma were found in 11 cases and the incidence was 18.33%(11/60), only two cases reported with uncomfortable light pain in the location of subcutaneous injection.Conclusion Low-dose LMWH is safe and effective in the therapy of pregnant women with RSA through ART.

To establish a highly sensitive and specific method to detect the presence of Cryptosporidium homini, the RT-PCR-ELISA assay was tried, in which the primer with a biotin-labeled probe was designed to amplify fragment containing the highly variable region by multiple alignment between p23 gene of C.hominis and other Cryptosporidium spp. The RT-PCR was used to amplify the target fragment, and the amplified product was used to hybridize with the probe primer. The hybridized product was then captured on micro-plate wells coated with streptavidin and reacted with anti-digoxin antibody labeled with horse-radish peroxidase. This method of testing was then used for the detection of C.hominis in 22 clinical specimens and compared with the conventional methods of testing. It was demonstrated that the RT-PCR--ELISA for the detection of C.hominis was proved to be quite sensitive and specific. Its sensitivity was 100 times higher than that of the general PCR. From the result of clinic detection, the detection rate of RT-PCR-ELISA assay attained to 86%(19/22), while those of RT-PCR, sucrose floating method and anti-acid staining were 27%, 27% and 50% respectively. This result indicates that the RT-PCR-ELISA assay is more sensitive to detect C.hominis than the other three methods of testing.

Fragile X syndrome (FXS) is the most common monogenic disease that causes intellectual disability and autism spectrum disorder (ASD),causing moderate to severe mental retardation with unusual facial features and connective tissue abnormalities.Fragile X syndrome is caused by the mutation of FMR1 gene,resulting in the reduction or loss of its product,fragile X mental retardation protein (FMRP).The diagnosis is mainly based on the detection of FMR1 gene,and there is no effective treatment for fragile X syndrome.Therefore,it is very important to strengthen genetic counseling and prenatal diagnosis,and effectively reduce the incidence of fragile X syndrome.

Objective To investigate the expression of WD repeat-containing protein 5(WDR5)in cervical cancer tissue and its relationship with clinical pathological characteristics and prognosis of patients.Methods 105 CA patients admitted to our hospital from January 2018 to March 2020 were included as the study subjects,the cancer tissue and adjacent tissue samples of patients were collected,Immunohistochemical staining and Western blot were used to detect the level of WDR5 in CA tissue and adjacent cancer tissues.Immunohistochemistry and Western blot were used to determine the level;Survival analysis was conducted using the Kaplan Meier method;The influencing factors of patient prognosis were analyzed through Cox regression.Results Among 105 CA tissue samples,the positive expression rate of WDR5(WDR5 positive cases/total cancer tissue cases)was 68.57% (72/105),which was higher than 22.86% (24/105)in adjacent cancer tissues(P<0.05);Compared to adjacent tissues(1.00±0.11),the expression level of WDR5 was higher in CA tissues(4.66±0.98)(t = 38.030,P<0.05).The expression level of WDR5 is related to the degree of differentiation,TNM staging,and lymph node metastasis(P<0.05);The survival rate of WDR5 positive expression was 65.28% (47/72)lower than that of negative expression of 90.91% (30/33)(Log rank χ2 = 6.732,P = 0.009);TNM staging,WDR5,degree of dif-ferentiation,and lymph node metastasis are all influencing factors for patient prognosis(P<0.05).Conclusion The expression of WDR5 is elevated in cervical cancer tissues,and its changes are closely related to TNM staging,differentiation,lymph node metastasis,and prognosis in cervical cancer patients.

ObjectiveTo observe the effects of Wendantang on the expression of inflammatory cytokines， autophagy markers， and key molecules of phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway in the adipocytes of the rat model of obesity （syndrome of phlegm-dampness） and to explore the material basis of inflammation in obesity （syndrome of phlegm-dampness） and the underlying mechanism of Wendantang intervention. MethodA total of 126 SD rats were randomized into 2 groups： 16 rats in the blank group and 110 rats in the modeling group. The blank group was fed with a basic diet while the modeling group with a high-fat diet to establish the animal model of obesity （syndrome of phlegm-dampness） for 8 weeks. After successful modeling， 48 obese rats were selected according to their body mass and randomized into a model control group， an orlistat （ORLI， 32.40 mg·kg^-1） group， a rapamycin （RAPA， 2 mg·kg^-1） group， and low-， medium-， and high-dose （4.45， 8.90， 17.80 g·kg^-1， respectively） Wendantang groups， with 8 rats in each group. In addition， 8 rats were randomly selected from the blank group to be set as the normal control group. The corresponding agents in each group were administrated by gavage and the model and control groups were administrated with equal amounts of distilled water once daily for 6 weeks. The body mass， Lee's index， body fat ratio， and obesity rate were measured or calculated. The expression of UNC51-like kinase-1 （ULK1）， Beclin1， human autophagy-related protein 5 （Atg5）， p62， and microtubule-associated protein 1 light chain 3 （LC3） Ⅰ/Ⅱ （markers of autophagy in adipocytes） was detected by the immunohistochemical two-step method. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the expression of tumor necrosis factor （TNF）-α， interleukin-6 （IL-6）， IL-1β， monocyte chemotactic protein-1 （MCP-1）， IL-4， IL-10， IL-13， and transforming growth factor （TGF）-β in adipocytes. Western blot was employed to measure the protein levels of classⅠ-PI3K， phosphatidylinositol triphosphate （PIP3）， Akt， mTORC1， ULK1， TSC1， and TSC2 in adipocytes. ResultCompared with the blank group， the modeling group showed increased body mass and Lee's index （P<0.01）， the obesity rate >20%， and phlegm-dampness syndrome manifestations such as physical obesity， decreased mobility， decreased appetite， lusterless and tight fur， loose stools， decreased responsiveness to the outside world， and decreased water intake. Compared with the normal control group， the model control group showed increased body mass， Lee's index， body fat ratio， adipocyte autophagy marker expression， pro- and anti-inflammatory cytokine levels （P<0.05， P<0.01）， down-regulated protein levels of classⅠ-PI3K， PIP3， Akt， mTORC1， TSC1， and TSC2 （P<0.01）， and up-regulated protein level of ULK1 （P<0.01）. The intervention groups showed lower body mass， body fat ratio， adipocyte autophagy marker protein expression， and protein levels of TNF-α， IL-6， IL-1β， MCP-1， IL-4， and IL-13 than the model control group （P<0.05， P<0.01）. Moreover， the RAPA and Wendantang （medium and high dose） groups showed lowered levels of IL-10 and TGF-β （P<0.01）， and the ORLI group showed down-regulated expression of TGF-β （P<0.01）. The expression of key molecules of the signaling pathway was up-regulated （P<0.05， P<0.01） while that of ULK1 was down-regulated （P<0.01） in all the intervention groups. Compared with the RAPA group， the Wendantang groups showed up-regulated expression of all autophagy marker proteins in adipocytes （P<0.01）. In addition， the low-dose Wendantang group showed elevated levels of inflammatory cytokines （except TNF-α） （P<0.05， P<0.01） and down-regulated expression of all key molecules of the signaling pathway （P<0.05， P<0.01）. The levels of inflammatory cytokines （except IL-16， MCP-1， and IL-10） were elevated in the medium-dose Wendantang group （P<0.05， P<0.01）. The expression of key molecules except PI3K of the signaling pathway was down-regulated in the medium- and high-dose Wendantang groups （P<0.05， P<0.01）. Compared with the ORLI group， low- and medium-dose Wendantang groups showed up-regulated expression of autophagy markers in adipocytes （P<0.01）， and the low-dose group showed elevated levels of inflammatory cytokines （IL-6， IL-4， and TGF-β） （P<0.01） and down-regulated expression of all key molecules of the signaling pathway （P<0.01）. The medium-dose Wendantang group showed up-regulated expression of IL-4 （P<0.01） and down-regulated expression of key molecules except PI3K of the signaling pathway （P<0.05， P<0.01）. The high-dose Wendantang group showed increased body mass， up-regulated expression levels of autophagy markers （ULK1， LC3 Ⅰ/Ⅱ） （P<0.05， P<0.01）， down-regulated expression of PIP3， mTORC1， and TSC1 （P<0.05， P<0.01）， and lowered levels of Beclin1， Atg5， TNF-α， and IL-13 （P<0.05， P<0.01）. ConclusionThe inflammation in obesity （syndrome of phlegm-dampness） is closely associated with the PI3K/Akt/mTOR pathway-mediated adipocyte autophagy. Wendantang can treat the chronic inflammation in obese rats with the syndrome of phlegm-dampness by regulating this signaling pathway and thus improve adipocyte autophagy.
