Objective To study the effects of BCG-PSN on the expression of the receptor of selectins——one of the important cell adhesion molecules, and the characteristics of cytoskeleton structure in lung cancer cells. Methods The effects of BCG-PSN on the expression of sialyl Lewis X (slex) and the cytoskeleton structure of highly metastatic human pulmonary giant cell carcinoma (PG) cells and lowly metastatic human pulmonary adenocarcinoma (PAa) cells were observed by flow cytometry and transmission electron microscopy. Results Flow cytometric results showed that the expression of slex on the surface of PAa cells (66.8%) was higher than that on PG cells (5.72%). After treatment with BCG-PSN, the expression of slex on PAa cells decreased in a dose-dependent manner. Transmission electron microscopy showed that the microtubules and microfilaments were sparse in the PAa cells and diminished in PG cells. After treatment with BCG-PSN, the microfilaments were more abundant than before in PG cells and showed a branch-like appearance, but still remained sparse in PAa cells. Conclusion Changes in the components of the cytoskeleton structure are associated with the ability of the migration and movement of the tumor cells. The inhibitory effect of BCG-PSN on the adhesiveness of lung cancer cells may not be the cytoskeleton-mediated enhancement of adhesion, but the start-up process resulted from the down-regulation of cell adhesion molecules on the surface of lung cancer cells.

Objective To analyze the therapeutic effect ofShengji-Yuhong ointment in the treatment of patients with pressure ulcer.Methods 86 patients of pressure ulcer were randomly divided into a control group and an observation group, with 43 cases in each. After debridement, the wound was covered with vaseline gauze in the control group, whileShengji-Yuhong ointment in the treatment group. 10 days constituted 1 course of treatment, and both groups were treated for 3 courses. The blood supply of the whole blood viscosity, plasma viscosity, erythrocyte aggregation index detection; white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C reactive protein (CRP) were observed in order to observe the control condition of the patients with wound infection.Results The total effective rate was 95.3% (41/43) and 74.4% (32/43) in the observation group and control group respectively, with significant difference between two groups (χ2=5.800,P=0.016). After treatment, the whole blood viscosity (high-shea) (4.06 ± 1.38 mPa?svs. 4.74 ± 1.62 mPa?s,t=2.095), the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.34 ± 1.41 mPa?s,t =2.216), blood reduction viscosity (1.13 ± 0.22 mPa?svs.1.44 ± 0.51 mPa?s,t=3.660), the whole blood viscosity (medium-shea) (4.16 ± 0.48 mPa?svs. 4.51 ± 0.89 mPa?s,t=2.270) obviously compared with group before treatment decreased (P<0.05). The patients in the observation group in the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.16 ± 0.48 mPa?s,t=2.251), and blood reduction viscosity (1.13 ± 0.22 mPa?svs. 1.32 + 0.31 mPa?s,t=3.278) in the observation group were  obvious better than the control group (P<0.05). After the treatment the WBC, CRP, ESR in the observation group were decreased significantly than the control group (t=5.947, 7.198, 12.064,P<0.01).ConclusionShengji-Yuhong ointment can effectively control the PU infection in the wound, improve wound tissue under the blood circulation, and promote wound healing.

Objective:To describe the clinical features and immunological of Uygur systemic lupus erythematosus (SLE) subjects.Methods:Atotal of 484 adult patients (≥18 years) followed in the People's Hospital of the Xinjiang Uygur Autonomous Region were included into this study including 211 Uygur patients with SLE and 273 Han patients with SLE.Results:① Of the 211 Uygur SLE patients, 195 (92.4%) were female and 16(7.6%) were male (female:male=12.2∶1), the mean age at SLE onset was 15-64(35±12) years, mean disease duration was 0.1-228(21±35) months.② Of the 211 Uygur SLE patients, the most prevalent clinical presentationswere renal involvement 56.4%(119/211), hematological 56.4%(119/211), rash 50.2% (106/211), arthralgia/arthritis 49.8%(105/211), weakness 47.9%(101/211). The significant difference observed between the Uygur and Han SLE patients was Raynaud phenomenon( χ2=6.066, P=0.014) .③ The positive rates of antinuclear antibodies were 94.8%(200/211), 54.5%(115/211) for anti-dsDNA antibodies, 47.9% (101/211) for anti-SSA antibodies, 35.1%(74/211) for anti-U 1-RNP antibodies, and 28.4%(60/211) for anti-AHA antibodies. The positivity of anti-AHA antibodies ( χ2=4.952, P=0.026) was higher in Uygur SLE patients than thatin Han SLE patients. More Uygur SLE patients were anemic ( χ2=6.904, P=0.009), with decrease of complement ( χ2=6.330, P=0.012). Conclusion:This study can not find any significant differences between the Uygur SLE patients and Han SLE patients in common clinical manifestations in Xinjiang. The Uygur SLE patients are more likely to have anemia and decrease of complement, which may be related to race and diet habits.

Objective To observe expression levels of N-methyl-D-aspartate (NMDA) receptor and cholecystokinin (CCK) in the hippocampus and spinal cord in morphine withdrawal or tolerance mice treated by electroacupuncture or catgut embedding and explore the difference between the regulating effects of electroacupuncture and catgut embedding on morphine withdrawal and tolerance.Methods Fifty-six male C57BL/6J mice were randomly allocated to withdrawal control, withdrawal model, withdrawal catgut embedding and withdrawal electroacupuncture groups, and tolerance control, tolerance model, tolerance catgut embedding and tolerance electroacupuncture groups, 7 mice in each group. A model of morphine withdrawal was made by subcutaneous injection of morphine hydrochloride using 7-day increasing addiction method. The withdrawal control group was injected with an equal volume of normal saline at the same time points. In the withdrawal electroacupuncture group, electroacupuncture at bilateral points Shenshu was performed using a Han’s acupoint nerve stimulation device (HANS-200) at 15 min after an injection of morphine hydrochloride. In the withdrawal catgut embedding group, 0.5 cm chromic catgut was embedded in bilateral points Shenshu at 15 min after an injection of morphine hydrochloride. Addiction was promoted by intraperitoneal injection of naloxone 4 mg/kg at 10 o’clock on the seventh day’s morning and Withdrawal reactions were observed in the mice. The score was recorded using the Ryuta Tomoji opioid withdrawal symptoms evaluation scale. NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by enzyme-linked immunosorbent assay (ELISA). A model of morphine tolerance was made by subcutaneous injection of morphine 10 mg/kg. The tolerance control group was injected with tolerance normal saline 10 ml/kg at the same time. In the tolerance catgut embedding group, catgut was embedded in point Shenshu at the first day after model making. In the tolerance electroacupuncture group, point Shenshu was given electroacupuncture at the first day after model making. After seven days of treatment, NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by ELISA.Results There were statistically significant differences in hippocampal NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There was a statistically significant difference in hippocampal NR2B expression between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the withdrawal catgut embedding or withdrawal electroacupuncture group and the withdrawal model group (P<0.05). There were statistically significant differences in spinal cord NR2A, NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There were statistically significant differences in spinal cord NR2A and NR2B expressions between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There were statistically significant differences in hippocampal NR2A, NR2B and CCK expressions between the tolerance model and tolerance control groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the tolerance catgut embedding and tolerance model groups (P<0.05). There was a statistically significant difference in hippocampal NR1 expression between the tolerance electroacupuncture group and the tolerance model or tolerance catgut embedding group (P<0.05). There was a statistically significant difference in spinal cord CCK expression between the tolerance catgut embedding or withdrawal electroacupuncture group and the tolerance model group (P<0.05).Conclusions Both catgut embedding and electroacupuncture at point Shenshu have a reducing effect on morphine tolerance and withdrawal. The therapeutic effect of electroacupuncture is better than that of catgut embedding.

Objective:To explore the depression of patients with systemic lupus erythematosus (SLE) during the coronavirus disease 2019 (COVID-19) pandemic.Methods:Patients with SLE and healthy subjects(control group) from August 16, 2020 to September 2, 2020 in Urumqi, Xinjiang were collected. The depression and sleep quality were assessed by Self rating Depression Scale (SDS) and Pittsburgh sleep quality index (PSQI). The nonparametric data were represented by median (quartile spacing), and the rank sum test was used to compare the continuous variables between the two groups. Pearson correlation test was used for continuous variables, and Spearman correlation test was used for rank variables or classified variables. Statistical product and service solutions.Results:The prevalence rate of depression in the SLE group (41.9%) was significantly higher than that in healthy control group (32.1%). The difference was statistically significant ( χ2= 10.312, P<0.01). The prevalence rate of poor sleep in the SLE group (31.8%) was significantly higher than that in healthy control group (21.6%). The difference was statistically significant( χ2=3.885, P=0.049). The total score of VAS ( OR=1.366, P<0.01) , PSQI( OR=1.198, P<0.01) were the risk factor of depression in patients with SLE. Conclusion:SLE patients have a higher prevalence of depression during pandemic quarantinee-period, pain and poor sleep quality are risk factors. We need to pay attention to the psychological status of SLE patients.

The adhesion properties of tumor cells with extracellular matrix(ECM) are closely associated with their invasion and metastasis.Our work reported here was intended reveal the relevant biomechanical and biorheological manifestations of human lung cancer. Using micropipette aspiration technique, we investigated quantitatively the adhesive mechanics properties of high metastatic human giant cell carcinoma(PG) cells as well as low metastatic adenocarcinoma(PAa) cells of lung based on cell culture in vitro. The results showed that the adhesion forces of PAa and PG cells to collagen Ⅳ were significantly higher than those to glass surfaces, but at the lower concentrations(1.00μg/ml and 2.00μg/ml) of collagen Ⅳ, the amplitude for the increase of adhesion forces of PG cells were less than the amplitude for that of PAa cells, and most of the adhesion force values of PAa cells to the coated surfaces of incorporation of laminin along with 2 μg/ml collagen Ⅳ were significantly greater than those of PG cells. At the lower concentrations(0.625μg/ml for PAa cells,and 0.625 μg/ml, 1. 25 μg/ml for PG cells) of laminin tested,the adhesion force values of PAa and PG cells all decreased, but the amplitude and level for the decreased values of adhesion forces of PG cells were greater than those for the PAa cells. In conclusion, the adhesive and proteolytic behaviour of cancer cells to extracellular matrix might be mediated mainly by tumor cell membrane receptors such as integrin receptors and laminin receptors, it might affect the biological characteristics and the metastasis of the tumor cells. The results may benefit to explain some questions in biomechanical views about how the highly metastatic PG cells are prone to migration and invasion.

Objective: To assess the association between lupus nephritis disease activity and anti-C1q antibodies. Methods: The study analyzed the medical records of 98 patients with lupus nephritis (LN), 35 patients without lupus nephritis. LN disease activity was measured by the systemic lupus international collaborating clinics (SLICC) renal activity score of 2008. All biopsied tissues were scored based on the International society of nephrology/Renal pathology society (ISN/RPS) 2003 LN pathological typing standards, acute and chronic index scores were used to evaluate the activities of lupus. All patients were test for the levels of anti-dsDNA and anti-C1q antibodies using the enzyme-linked immuno sorbent assay (ELISA), C3, C4, 24-hour urinary protein performed in parallel. For normally distributed quantitative parameters, the differences between groups were assessed by t test. Mann-Whitney U test was performed for non-normally distributed data. The cut-off values were evaluated by using receiver operating characteristic (ROC). The Spearman methods were used to test correlations. Results: Patients with LN had a higher levels of anti-C1q antibodies than patients without lupus nephritis [3.94 (10.2, 91.3) AU/ml与6.9 (2.0, 15.4) AU/ml; Z=-4.299, P<0.01]. Patients with inactive lupus nephritis had higher levels of C1q, C3, C4 than active LN (t=2.393, 3.777, 2.557; P<0.05). Patients with active lupus nephritis had higher levels of anti-C1q antibodies than inactive LN (Z=-4.632, P<0.01). Anti-C1q antibody levels were positively correlated with levels of 24-hour urinary protein, AI score (r=0.327, P<0.01) and SLICC score (r=0.493, P<0.01), and were negatively correlated with serum C1q (r=-0.373, P<0.01), C3 (r=-0.532, P<0.01) and C4 (r=-0.463, P<0.01). The optimal cutoff value of Anti-C1q for a diagnosis of active LN was 48.9 RU/ml, and the sensitivity and specificity were 62.5% and 80%, respectively. The area under the curve (AUC) was 0.771. Conclusion Anti-C1q antibodies are more closely correlated with renal disease activity, and anti-C1q antibody is an important serum marker for monitoring LN activity, but its pathological mechanism in the pathogenesis of LN still needs to be further explored.

Objective: To investigate the expression of NAD (P) H: quinone oxidoreductase 1 (NQO1) and heme oxygenase-1 (HO-1) in T-cell lymphoma (TCL), and investigate the correlation between these two indicators and other clinicopathological parameters in TCL. Methods: Clinical data of 61 patients with TCL who were initially diagnosed in Gansu Provincial Hospital were analyzed retrospectively. Immunohistochemical examination was performed to detect NQO1 and HO-1 expression levels in 61 TCL tissues (TCL group) and 20 lymph node reactive hyperplasia tissues (control group). Results: Positive expression rates of NQO1 and HO-1 were significantly higher in TCL tissues than in lymph node reactive hyperplasia tissues (P<0.05). NQO1 expression was closely related with Ann-Arbor clinical stage and B symptoms (P<0.05); HO-1 expression was correlated with clinical stage, bone marrow invasion, and B symptoms (P<0.05). NQO1 and HO-1 expression levels were not related to age, sex, lactate dehydrogenase level, and pathological type (P>0.05); there was a correlation between NQO1 and HO-1 expression (r=0.264; P=0.040). Conclusions: NQO1 and HO-1 are highly expressed in TCL and may interact and contribute to the occurrence and development of TCL.

This study was aimed to reveal characteristics of functions, main indications and applications of Chinese patent medicines in order to provide references for development of new Chinese patent medicines for antitussive ef-fect. Chinese patent medicines recorded in the Pharmacopoeia of the People's Republic of China and the New Na-tional Chinese Patent Medicines were taken as research subjects. Chinese patent medicines classified in the function and indication with key words of cough-relieving, cough-suppressing, cough and chronic cough were col-lected. Analysis was made on the prescription characteristics, such as functions, main indications and applications. The results showed that there were 684 Chinese patent medicines and 462 terms, which were used for a total of 1533 times. The frequently-used terms are antitussive effect with expectorant, antitussive effect, expectorant, heat-clearing and exterior-releasing, antiasthmatic, wind-expelling and antipyretic, antitussive effect with antiasthmatic, purging lung heat, relieving exterior syndrome and moistening the lungs. All 684 Chinese patent medicines were used 48 ma-jor treatments for a total of 1107 times. The main indications include acute and chronic trachitis / bronchitis, exoge-nous wind-heat type of common cold, exogenous wind-cold type of common cold, cough with abundance of phlegm due to phlegm-heat obstructing the lung, acute upper respiratory tract infection, asthma, acute and chronic pharyngi-tis, lung heat cough, and etc. All 684 Chinese patent medicines used a total of 537 kinds of herbs and chemical medicines, including 441 kinds of herbal medicine, 36 kinds of animal medicine, 25 kinds of mineral medicine and 35 kinds of chemical medicine. The top ten herbs in terms of using frequency are Glycyrrhizae radix et rhizoma, Platycodonis radix, Armeniacae semen amarum, Menthae haplocalycis herba, Citri reticulatae pericarpium, Ephedrae herba, Scutellariae radix, Perilla frutescens (L.) Britt, Pinelliae rhizoma, Fritillariae cirrhosae bulbus. Among them, 1/4 of Chinese patent medicines used extract. Five kinds of food or fruits were also used, which were orange, fresh gin-ger, pear, watermelon and dried mushroom. It was concluded that Chinese patent medicines for antitussive effect can be adopted in the treatment of various kinds of diseases, especially for the treatment of cough(heat cough in partic-ular), abundance of phlegm, asthma, pharyngitis, laryngitis, and etc. The treatment methods of clearing heat, dis-pelling wind and relieving exterior syndrome played an important role in the realization of antitussive effect. However, the expression of functions and main indications is far from standardized and clear. Drugs commonly used are herbal medicine plus animal medicine, mineral medicine and chemical medicine as well as food and fruit. The discovery of preparations with certain clinical curative effect from ethnomedicine and the using of their extracts as a major ingre-dient are one important way to develop new Chinese patent medicines with antitussive effect.

Objective To investigate the role of interleukin-22 (IL-22)-regulated autophagy in hydrogen peroxide (H2 O2 )-induced hepatocarcinoma cell damage. Methods HepG2 cells were transfected with pEGFP-LC3 and then cultured in RPMI 1640 medium free of fetal bovine serum (FBS) or containing 1％ or 10％ FBS. These cells were pretreated with rapamycin or an autophagy inhibitor (3-MA) and then stimulated with recombinat human IL-22 (rhIL-22). GFP-LC3 puncta formation and autophagy signaling ac-tivation were measured. MTT assay was performed to detect cell viability. Results rhIL-22 significantly promoted GFP-LC3 puncta formation and LC3-Ⅱ expression in HepG2 cells treated with different stimulation protocols. The autophagy pathway inhibitor, 3-MA, dramatically suppressed the rhIL-22-activated autophagy signals. rhIL-22 attenuated H2 O2-mediated HepG2 cell death and that could be inhibited by 3-MA. Conclu-sion IL-22 promoted the activation of autophagy signaling pathways and alleviated H2 O2-mediated HepG2 cell damage.
