Objective Non-small-cell lung cancer with ipsilateral mediastinal lymph node metastasis (N2) belongs to heterogeneous subgroup. We analyzed the prognosis of patients with resected N2 NSCLC to determine the clinical significance. Methods The present study comprised 146 consecutive patients whom underwent surgical resection of N2 NSCLC between January 1997 and January 2000. Histological type, location, T primary tumor status, operation mode, clinical N2 (cN2) factor, N2 level(single or multiple), number of positive nodes(N2-num), and the cycles of adjuvant chemotherapy were estimated from the date of operation using the Kaplan-Meier and Log Rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results The 3-and 5-year survival rate of these N2 NSCLC patients were 19.86% and 14.56%, respectively. The patients with tumor in the right lower lobe showed a significantly longer survival than left lobes. The histological type, tumor location, cN2 factor, N2 level and N2-number were associated with survival. A multivariate analysis using Cox regression identified 4 factors of prognosis: tumor site, T status, N2 level and clinical N2 status. Conclusion This article has identified N2 NSCLC subgroups and found that patients with mN2, N2L1 and single N2 have better prognosis.

To guarantee the research and establishment of the modern basic theory of traditional Chinese medicine, We firstly proposed the concept of the academic standards of the modern basic theory of traditional Chinese medicine and its logical structure and standards points in this paper. According to the research progress at home and abroad, we explored the basic concept of academic, academic standards, academic of Chinese medicine, academic standards of Chinese medicine in depth, given the logical definition of relevant concepts, and revealed the connotation and logical hierarchy relationship between different concepts. On this basis, we proposed three-level standards points of the academic standards of Chinese medicine. All of these works mentioned above would provide a preliminary standards protection for the academic research of traditional Chinese medicine and the establishment of the modern basic theory of traditional Chinese medicine.

Objective To study the role of cutaneous nerve and protease activated receptor 2 (PAR2)in the development of pruritus in atopic dermatitis(AD).Methods Dermal sheets were prepared from chronically pruritic skin lesions of 7 patients with AD,as well as from the normal skin of 7 healthy human controls.Double labeled immunofluorescence was performed using mouse anti-protein gene product 9.5(PGP9.5)monoclonal antibody and rabbit anti-substance P(SP)polyclonal antibody to observe the morphological changes in cutaneous nerve fibers,and Image-Pro Plus 6 software was used to semiquantitively assess the length,diameter of nerve fibers,integral optimal density of PAR2 and SP in dermal sheets.Results Immunofluoresence double staining showed that PAR2 co-expressed with PGP9.5 or SP in cutaneous nerve fibers.Compared with the normal control skin,both the total length and average diameter of PGP 9.5-expressing nerve fibers were increased(11051.8±1900.9 μm vs 7264.0±2659.9 μm,4.23±0.15 μm vs 3.95±0.15 μm,both P＜0.01)in pruritic lesions,while only the average diameter of SP-expressing nerve fibers was up-regulated(3.99±0.20 μm vs 3.80±0.07 μm,P＜0.05),and the total length of them remained unchanged(4304.7±1455.0 μm vs 3380.0±1735.4 μm,P＞0.05).Also,increased integral optimal density was observed for SP and PAR in pruritic lesions in comparison with the normal control skin (27.71±16.52 vs 12.63±4.31.35.99±8.63 vs 22.69±9.56.both P＜0.05).Conclusion Our results indicate a hyper-plasia of cutaneous nerve fibers in chronic itchv skin lesions of AD and an increase in the expression of PAR2 and SP in the cutaneous nerve fibers,suggesting that the signal enhancement in PAR2 pathway may be related to the mechanism of pruritus in patients with AD.

Objective: To investigate the role of nuclear factor ?B (Rel/NF-?B) in pathogenesis of atopic dermatitis(AD) and the effect of topical 0.1%(mass fraction) or 0.03%(mass fraction) tacrolimus ointment on expression of NF-?B in lesional AD skin. Methods: Immunohistochemistry has been employed to study the expression of NF-?B in normal skin and lesional AD skin before and after using topical tacrolimus ointment. Results: The expressions of NF-?Bp50 and NF-?Bp65 were scattering or negative in normal keratinocytes. NF-?Bp50 was overexpressed on nuclear of basal and suprabasal keratinocytes in 9 cases of AD, NF-?Bp65 was overexpressed in cytoplasm and perinuclear of basal and suprabasal keratinocytes. After using topical tacrolimus ointment for three weeks , nuclear NF-?Bp50 expressed on basal and suprabasal keratinocytes were lost and NF-?Bp50 was expressed sparsely on basal keratinocytes cytoplasm or nuclear. NF-?Bp65 was expressed sparsely on basal and suprabasal keratinocytes cytoplasm. Conclusion: These data suggest that increased NF-?B activity may represent the basis of initiation or maintenance of the skin inflammatory response in atopic dermatitis. Topical tacrolimus may directly or indirectly inhibit NF-?B nuclear expression in keratinocytes and inhibit skin innate immuno-inflammatory response in atopic dermatitis that related to NF-?B.

Objective To observe the clinical efficacy and safety of 0.1% and 0.03% tacrolimus ointment in patients aged 18 to 65 years with atopic dermatitis (AD). Methods Treatment was given twice daily to all affected areas for 3 weeks in a multicentre, randomized, double blind, parallel, and vehicle-controlled study. Follow-up visits were scheduled on day 1(baseline), and 1, 2 and 3 weeks post-treatment. The therapeutic effect and safety were evaluated. Results A total of 211 adults with moderate to severe AD in 6 study centres were enrolled in the efficacy evaluation. The efficacy rates were 88.4%, 77.8% and 30.0% in patients treated with 0.1%, 0.03% tacrolimus ointment, and the vehicle, respectively (P

Objective To evaluate the efficacy and safety of 0.03% tacrolimus ointment for the treatment of atopic dermatitis (AD) in Chinese children. Methods A total of 139 children, 2 to17 years of age, with moderate to severe AD from 5 study centres were enrolled in this multicentre, randomized, double-blind, vehicle-controlled, parallel group study. Treatment with 0.03% tacrolimus ointment or vehicle was applied twice daily to the affected areas for 3 weeks. Visits were scheduled on day 1 (base line, before treatment) and 1, 2, 3 weeks after the treatment. The main therapeutic parameter was the efficacy rate at the end of the treatment. Results The efficacy rates were 84.6% and 29.0% for tacrolimus group and vehicle group, respectively (P

Objective To sum up and analyze the clinical and pathological characteristics in patients with both IgA nephropathy (IgAN) and diabetes mellitus. Methods A total of 500 patients were recruited, including 25 patients with both IgAN and diabetes mellitus, and 475 patients with IgAN only, who were diagnosed by renal-biopsy during Jan 2015 to Jan 2017 at the First Affiliated Hospital of Zhengzhou University. The clinical and pathological data were collected and analyzed using SPSS 22.0. Propensity Score Matching was used to match and select the patients in the both groups, and thereafter the depth of the basement membrane from the matched patients were compared using electron microscopy. The data of the patients whose follow - up time was ≥3 months were retrospectively collected, and Kaplan-Meier analysis was used to compare the difference of the prognosis. Results Compared to the patients with IgAN only, patients with both IgAN and diabetes mellitus were older [(46.36±13.49) years vs (34.00±13.80) years, P<0.001], had higher level of serum triglyceride [2.06(1.52, 3.11) mmol/L vs 1.51(1.01, 2.25) mmol/L, P=0.012] and thicker basement membrane [(384.33 ± 61.20) nm vs (346.72 ± 52.65) nm, P=0.044]. The patients with both IgAN and diabetes mellitus were more prone to reach the composite endpoint [4/7(57.14％) vs 25/265(9.33％), P<0.001] and had worse prognosis (Log-Rank test, P=0.004). Conclusions IgAN patients with diabetes mellitus have different clinical, pathological characteristics and prognosis from patients with IgAN alone. These patients need to be closely monitored and actively treated.

Psoriasis (Ps) is an inflammatory skin disease caused by genetic and environmental factors. Previous studies on DNA methylation (DNAm) found genetic markers that are closely associated with Ps, and evidence has shown that DNAm mediates genetic risk in Ps. In this study, Consensus Clustering was used to analyze DNAm data, and 114 Ps patients were divided into three subclassifications. Investigation of the clinical characteristics and copy number variations (CNVs) of DEFB4, IL22, and LCE3C in the three subclassifications revealed no significant differences in gender ratio and in Ps area and severity index (PASI) score. The proportion of late-onset ( ≥ 40 years) Ps patients was significantly higher in type I than in types II and III (P = 0.035). Type III contained the smallest proportion of smokers and the largest proportion of non-smoking Ps patients (P = 0.086). The CNVs of DEFB4 and LCE3C showed no significant differences but the CNV of IL22 significantly differed among the three subclassifications (P = 0.044). This study is the first to profile Ps subclassifications based on DNAm data in the Chinese Han population. These results are useful in the treatment and management of Ps from the molecular and genetic perspectives.
