Objective To explore the possible role of proline-rich tyrosine kinase (Pyk2) in the pathogenesis of systemic lupus erythematosus (SLE).Methods The expression of Pyk2 in the peripheral blood mononuclear cells (PBMCs) of 50 patients with SLE and 36 healthy controls were tested with RT-PCR assay.The activation of Pyk2 was inhibited using specific inhibitor Pyk2 (TyrA9).Semi-quantitative PCR methodwas used to detect the Blys expression of PBMCs.One-way ANOVA and Pearson's correlation analysis were used for statistical analysis.Results The Pyk2 expression level (28.31 ±0.91) of SLE patients was significantly higher than that in healthy controls (33.69±0.04),the difference was statistically significant (P＜0.05).The activation of Pyk2 was stimulated and the expression levels of Blys in the PBMCs of patients with SLE was elevated.By inhibiting the activation of Pyk2,the BLyS expression levels decreased significantly.Conclusion Pyk2 may be involved in the abnormal activation of lymphocytes which lead to the pathogenesis of SLE.Pyk2 expression is associated with SLE disease activity,disease aggravation,and the Pyk2 expression levels is also increased significantly.In addition,the expression level of Pyk2 is higher in patients with renal involvement than those patients with other organ involvement.

Objective By detecting the expression levels of Foxp3 in CD4+CD25+ regulatory T cells of peripheral blood mononuclear cells (PBMCs) in rheumatoid arthritis (RA),and the Foxp3 gene promoter region methylation to explore its role in the pathogenesis of RA.Methods Twenty-five RA patients and 10 healthy controls were selected,and the PBMCs were extracted by density gradient centrifugation.Foxp3 expression levels of CD4+CD25+ regulatory T cells were detected by flow cytometry.The real-time fluorescence quantitative PCR assay was used to detect the Foxp3 mRNA expression in PBMCs; and bisulfate processing gene sequencing was used to determinethe differences in Foxp3 gene promoter sequence methylation level of PBMCs.The comparison between groups was analyzed using one-way ANOVA; two sets of qualitative data were compared using Fisher's exact test.Results The expression levels of Foxp3 mRNA in the CD4+CD25+regulatory T cells of active RA patients (2.31±0.25) was significantly lower than inactive RA group (3.68±0.26) and healthy controls (5.67±0.34),the difference was statistically significant (P＜0.05).The Foxp3 mRNA expression level in inactive RA group was lower than that of the healthy controls (P＜0.05).Foxp3 promoter region-67,-74 sites of methylation level in PBMCs of RA patients (46％) was significantly higher than that of the healthy controls (6％).Conclusion Reduction in the number of CD4+CD25+ regulatory T cells may be involved in the pathogenesis of RA and Foxp3 gene promoter methylation levels plays a key role in this process.

Objective To compare the improvement of peri-orbita rhytides and the patients' satisfaction treated by intense pulse light, Elos and activeFXTM fractional CO2 laser. Methods Two groups of the study were conducted. In first group, 42 volunteers in the hospital were enrolled. All were took photos to evaluate the peri-orbita rhytides by the physician before and one month after activeFX? treatment. Doctors and volunteers evaluated the improvement of peri-orbita rhytides and satisfaction together. In second group, a retrospective study was conducted, in which 40 patients were treated with intense pulse light, and other 40 patients treated with Elos in 2006-2007. Their improvements were analyzed through comparison of their photos before and one month after treatment, and the satisfaction was also evaluated. All data were analysed by SPSS10. 0. Results ActiveFXTM fractional CO2 laser is better than other two techniques for improving peri-orbita rhytides, and patients were more satisfied with this technology. Conclusion The improvement of peri-orbita rhytides and satisfaction treated by activeFXTM is higher than intense pulse light and Elos techniques.

Objective To study the mRNA expressions of Toll-like receptor (TLR) 2 and 4 in peripheral blood mononuclear cells (PBMCs) of patients with leprosy. Methods SYBR Green fluorescence quantitative RT-PCR was conducted to detect the mRNA expressions of TLR2 and 4 in PBMCs from 30 patients with cured leprosy, 30 patients with active leprosy and 30 normal human controls. Results The expression of TLR2 mRNA in patients with active leprosy was significantly higher than that in those with cured leprosy and in controls (both P ＜ 0.01 ), but there was no significant difference between the latter two groups (P ＞ 0.05). The expression of TLR4 mRNA was of no significant difference between patients with active leprosy and those with cured leprosy orthe controls (both P＞ 0.05). Conclusion The expression of TLR2 mRNA is decreased in PBMCs from leprosy patients, suggesting that TLR2 may be a specific recognition receptor in patients with leprosy.

Objective To assess the efficacy and safety of tacrolimus (TAC) combined with methotrexate (MTX) for the treatment of refractory rheumatoid arthritis (RA),and to compare it with cyclophosphamide (CTX) added to MTX for the treatment of refractory RA.Methods Thirty-six cases of refractory RA patients were divided into the observation group and the control group.TAC+MTX were used in the observation group,and CTX+MTX were used in the control group.We used repeated measures to analyze the variance and Fisher exact probability method to analyze the efficacy at 8 weeks and 24 weeks.Results The effective rate of the observation group in 8 weeks,24 weeks were 77.8％(14 cases) and 100％(18 cases) respectively,while those of the control group were 11.1％ (2 cases) and 44.4％(8 cases),it showed that both TAC+MTX and CTX+MTX in the treatment of refractory RA were effective,but the efficacy of TAC+MTX was better than CTX+MTX,the difference of C reactive protein (CRP) and disease activity score (DAS)28 was statistically significant (P＜0.05),and it could significantly improve the clinical symptoms and laboratory indexes.Conclusion TAC+MTX is effective and safe in treating refractory RA,and is worth of spreading.

OBJECTIVE:To investigate clinical efficacy and safety of Kang'ai injection adjuvant chemotherapy for advanced lung cancer. METHODS:A total of 146 patients with advanced lung cancer during May 2013-Apr. 2014 were divided into observa-tion group and control group according to odd-even admission number,with 73 cases in each group. Control group was given GP (gemcitabine+cisplatin)chemotherapy. Observation group was additionally given Kang'ai injection 60 mL added into normal saline 250 mL,qd,ivgtt,for consecutive 14 d each chemotherapy cycle,on the basis of control group. Both groups were given tropise-tron 5 mg for preventing gastrointestinal reaction during chemotherapy. A treatment course lasted for 3 weeks,and both groups were treated for 3 courses. Clinical efficacies of 2 groups were compared;the levels of serum inflammatory factors (hs-CRP, TNF-α,IFN-γ,IL-10),immune function indexes(CD3+,CD4+,CD8+,CD4+/CD8+)and tumor markers(SCC-Ag,CEA,CA50, CA72-4) were compared before and after treatment. The occurrence of ADR were recorded in 2 groups. RESULTS:The response rate and disease control rate of observation group were 39.73％ and 84.93％,which were significantly higher than 23.29％ and 71.23％ of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the lev-els of serum inflammatory factors,immune function indexes or tumor markers between 2 groups (P>0.05). After treatment,the levels of hs-CRP,TNF-αand IFN-γin 2 groups were significantly lower than before treatment,while the level of IL-10 was signifi-cantly higher than before treatment;above indexes of observation group were significantly better than control group,with statistical significance(P<0.05). The levels of CD4+ and CD4+/CD8+ in control group were decreased significantly and lower than observa-tion group,with statistical significance(P<0.05). Serum levels of SCC-Ag,CEA,CA50 and CA72-4 in 2 groups were decreased significantly,and observation group was significantly lower than control group,with statistical significance(P<0.05). The inci-dence of thrombocytopenia,neutropenia,abnormal liver function,nausea and vomiting,anemia in observation group were signifi-cantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Kang'ai injection adjuvant chemothera-py can effectively relieve inflammation symptoms of patients with advanced lung cancer,reduce toxic reactions,enhance immune function, and improve short-term therapeutic efficacy with good safety.

Objective:To observe the pathological changes of levator palpebrae superiors muscle in patients with different severities of simple congenital ptosis (SCP).Methods:Levator palpebrae superiors muscle specimens from 102 eyes of 68 patients with SCP who received levator palpebrae superiors muscle shortening surgery at Wuhan Aier Hankou Eye Hospital from August 2018 to October 2019 were collected as the observation group.According to the severity of ptosis, the specimens were divided into three groups, coverage ≤4 mm group (n=35), coverage >4 mm to ≤6 mm group (n=30), and coverage >6 mm group (n=37). Fresh levator palpebrae superiors muscle tissues from 8 normal donors in Aier Eye Bank of Wuhan Red Cross were selected as the control group.All specimens were performed with Masson trichrome staining and immunohistochemical staining for α-smooth muscle actin (α-SMA), and ImageJ software was used to measure the collagen fiber area ratio, skeletal muscle fiber area ratio and the integrated absorbance (IA) value of α-SMA.Seventeen specimens (2 from the control group, 5 from coverage ≤4 mm group/coverage >4 mm to ≤6 mm group/coverage >6 mm group) were observed with a transmission electron microscope (TEM). This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Wuhan Aier Hankou Eye Hospital (No.HKAIER2018IRB-005-01). All patients and their legal guardians were well informed about the treatment method and the purpose of sampling and voluntarily signed informed consent.Results:Compared with the control group, the skeletal muscle fiber was reduced in number and was in disordered arrangement, and the striation of some muscle fibers disappeared, and hyperplastic fibrous connective tissue was found in intercellular substances in the observation group.The collagen fiber area ratio of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group were significantly higher than that of the control group, and the skeletal muscle fiber area ratio of the three groups was significantly lower than that of the control group (all at P<0.008 3). There were more smooth muscle fibers and positive expression of α-SMA found in the specimens of the observation group.The IA value of α-SMA of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group was 7 195.28(5 935.69, 14 058.29), 55 584.18(33 861.88, 80 419.32), 166 507.76(119 121.95, 187 890.86), respectively, which were all higher than 5 543.03(4 867.67, 8 312.02) of the control group, among which, there were statistically significant differences between the control group and the coverage >4 mm to ≤6 mm group, coverage >6 mm group (both at P<0.008 3). Abundant organelles and some damaged mitochondria were found in smooth muscle cytoplasm in the observation group with a TEM.But no characteristic structure of smooth muscle cells such as dense patch and dense body was detected.Conclusions:There are abnormal smooth muscle cells in the levator palpebrae superiors muscle of SCP patients, and the dysgenesis of the levator palpebrae superiors muscle may be related to this abnormal muscle cell.
