IgG4-related disease (IgG4-RD) has been proved to be associated with malignancy.The incidence and risk factors of malignancy development in IgG4-RD were not clear.Nine IgG4-RD patients with malignancies and 27 IgG4-RD control cases were analyzed for risk factors and clinical features.The incidence of malignancy in IgG4-RD was 3.3％,higher than age-controlled general population.Smoking history was significantly more common in patients with malignancies than in the control group (9/9 vs 16/27,P ＜ 0.05).A total of 6/9 malignancies occurred within the first year after the diagnosis of IgG4-RD.Colorectal,biliary and thyroid cancers were the leading types.Smoking history is a risk factor for IgG4-RD associated malignancy.Careful vigilance to monitor malignancy needs to be paid during follow-up.

ObjectiveTo evaluate the effect of N-acetylcysteine (NAC) on alleviating hepatorenal damage caused by combined chemotherapy using cisplatin-based regiments in elderly patients. MethodsAll 40 elderly patients with malignant tumors were randomly divided into AB and BA group in cross-over pattern. In AB group, combination of chemotherapy and NAC was administrated for 10 days first, and then combination of chemotherapy, carnine and vitamin C was given for 10 days. In BA group, combination of chemotherapy, earnine and vitamin C was administrated for 10 days first, and then combination of chemotherapy and NAC was given for 10 days, a cycle was 21 days. The hepatorenal damage degree was observed and the curative effect of NAC on hepatorenal damage was evaluated. ResultsThere were no differences in the levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and serum creatinine(Cr) between pre chemotherapy and post chemotherapy in A cycle[(25.32±5.23) U/L vs. (29.18±5.43) U/L,(29.21±6.51)U/L vs. (32.37±7. 13)U/L, (89.87±19.56)Mmol/L vs. (95.22±20. 60)μmol/L,all P>0. 05] . In B cycle, the levels of ALT,AST and Cr were (56.76±5.53) U/L, (48.83±6.64)U/L and (137.33±21.16)μmol/L post chemotherapy, respectively, which were evidently higher than pre chemotherapy[(26.19 ± 5.51) U/L, (29.95±6.56) U/L and (88.66±18.27)μmol/L,respectively] (all P<0.01) . ConclusionsNAC has better preventive and therapeutic effects on hepatorenal damage caused by the chemotherapeutic drugs in elderly patients with malignant cancer.

Endocrine disrupting chemicals (EDCs) are natural or man-made agents that interfere in some way with human or animal normal endocrine function, and even influence the endocrine function of their offspring. There are many kinds of EDCs, which are widely present in soil, water, and even food. This review elaborates the impact of EDCs on human and animal semen quality from the viewpoint of epidemiology and biology by focusing on pesticides, plasticizers and detergents.

"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

Objective To investigate the effects of sex hormone-binding globulin (SHBG)gene in the apoptosis of human trophoblastic cells.Methods The siRNA specific-targeting SHBG gene was transfected into human trophoblastic cells and they were divided into six groups:trophoblasts without transfection in normal control groups(group Ⅰ);transfect liposome in blank control groups(group Ⅱ);transfect nonspecific siRNA in negative control groups(group Ⅲ);transfect SHBG siRNA-Ⅰ,SHBG siRNA-Ⅱ,SHBG siRNA-Ⅲ respectively in trans-fection group(group Ⅳ,Ⅴ,Ⅵ).Hoechst 33258 dying method was used to detect cell apoptosis.SHBG and Caspase-3 mRNA profiling and the level of SHBG and caspase-3 protein were detected by real-time PCR and Western blot.Results There was no statistical significant difference in the gene expression and protein level of SHBG and caspase-3 in group Ⅰ,Ⅱ and Ⅲ (P >0.05).In Ⅳ,Ⅴ and Ⅵ group,there was no statistical significant difference in the expression level of SHBG and caspase 3 (P >0.05).Compared with group Ⅰ,Ⅱ and Ⅲ,the a-mount of SHBG gene expression decreased obviously,the caspase-3 mRNA and protein level increased obviously and the trophoblast cell ap-optosis increased markedly (P <0.05).Conclusion Through siRNA interference technology can reduce SHBG gene expression in human trophoblastic cells,and it can lead to excessive apoptosis of human trophoblasts cells.

Objective:To observe the clinical effect of warm needling moxibustion plus acupoint sticking therapy for cervical radiculopathy.Methods:A total of 120 cases were allocated into an observation group,a warm needling group and an acupoint sticking group according to the random number table,with 40 cases in each group.Cases in the observation group received warm needling moxibustion plus acupoint sticking therapy;cases in the warm needling group received the same warm needling moxibustion in the observation group;cases in the acupoint sticking group received the same acupoint sticking therapy in the observation group.The scores of Japanese Orthopaedic Association (JOA) and visual analog scale (VAS) were recorded before and after treatment.Results:The total effective rate was 95.0％ in the observation group,versus 77.5％ in the warm needling group and 75.0％ in the acupoint sticking group (both P＜0.05).Inter-group differences in JOA and VAS between the observation group and the other two groups were statistically significant (all P＜0.05).Conclusion:Warm needling moxibustion plus acupoint sticking therapy is effective in treating cervical radiculopathy,and it can significantly alleviate pain and enhance clinical efficacy,and thus is worth clinical popularization.

Objective To analyze the temporal and spatial variation characteristics of six common air pollutants in Xi'an, and to provide a scientific basis for the environmental protection departments to conduct targeted prevention and control. Methods Based on air pollution monitoring data with high temporal resolution, the temporal and spatial distribution characteristics of six common air pollutants in Xi_'an were analyzed, and the correlation between the pollutants was studied. Results Except for O_{3_8h}, the annual average concentrations of the other five air pollutants decreased year by year. By 2020, the annual average concentration of PM_2.5 and PM₁₀ still exceeded the second-level concentration limit. The annual average concentration of NO₂ was slightly higher than the first-level concentration limit, and the number of unqualified days of O_{3_8h} accounted for one-tenth of the entire year. The concentrations of PM_2.5, PM₁₀, CO, SO₂, and NO₂ all were the highest in winter, equivalent in spring and autumn, and the lowest in summer. The concentration of O_{3_8h} generally presented the characteristics of summer > spring > autumn > winter. In 2020, the annual average concentrations of PM_2.5 and PM₁₀ in 9 urban areas exceeded the second-level concentration limit. The annual average concentrations of NO₂ in Xincheng District, Lianhu District, Beilin District, and Yanta District all exceeded the second-level concentration limit. The annual average concentration of O_{3_8h} in Beilin District, Chang'an District, and Yanliang District all exceeded the average level of Xi'an. PM_2.5, PM₁₀, CO, SO₂, and NO₂ in general showed a positive correlation in varying degrees. In summer, O_{3_8h} showed a positive correlation with other air pollutants, but a negative correlation in other seasons. Conclusion The air pollution situation in Xi'an has been improving year by year, but the pollution of PM_2.5, PM₁₀, and O_{3_8h} still exceeds the standard, which will be the focus of long-term prevention and control of air pollution in Xi'an.
