Preliminary Research on Syndrome Types of Chinese Medicine in Children with Primary Nephrotic Syndrome / 中国结合医学杂志

<p><b>OBJECTIVE</b>To provide an objective reference for the syndrome types of Chinese medicine (CM) associated with pediatric primary nephrotic syndrome (PNS).</p><p><b>METHODS</b>A cross-sectional study was performed. Data on clinical symptoms, CM syndrome types, biochemical indices, and medications used were collected from 98 children with PNS. Then, the correlation between CM syndromes and biochemical indices, as well as medications used, was analyzed.</p><p><b>RESULTS</b>The four most common symptoms in children with PNS were brown urine, red tongue, excessive sweating, and swelling of the face and limbs. The syndromes of qi deficiency of Fei (Lung) and Shen (Kidney) (FSQD) and yin deficiency of Gan (Liver) and Shen (GSYD) were the most common main CM syndrome types. FSQD syndrome score correlated significantly with the total cholesterol level, urine protein/creatinine ratio, and urine IgG and albumin levels (P<0.01 or P<0.05). The use of maintenance glucocorticoids combined with immunosuppressive agents correlated with FSQD syndrome, and the use of maintenance glucocorticoids alone correlated with GSYD syndrome (P<0.05).</p><p><b>CONCLUSION</b>Two of the most common CM syndrome types were FSQD and GSYD syndromes. FSQD syndrome may be caused by some factors related to lipid levels, protein loss, and the use of immunosuppressive agents. The use of maintenance glucocorticoids may cause GSYD syndrome.</p>

Prognostic value of the neutrophil to lymphocyte ratio in lung cancer: A meta-analysis

Recently, a series of studies explored the correlation between the neutrophil to lymphocyte ratio and the prognosis of lung cancer. However, the current opinion regarding the prognostic role of the neutrophil to lymphocyte ratio in lung cancer is inconsistent. We performed a meta-analysis of published articles to investigate the prognostic value of the neutrophil to lymphocyte ratio in lung cancer. The hazard ratio (HR) and its 95% confidence interval (CI) were calculated. An elevated neutrophil to lymphocyte ratio predicted worse overall survival, with a pooled HR of 1.243 (95%CI: 1.106-1.397; Pheterogeneity=0.001) from multivariate studies and 1.867 (95%CI: 1.487-2.344; Pheterogeneity=0.047) from univariate studies. Subgroup analysis showed that a high neutrophil to lymphocyte ratio yielded worse overall survival in non-small cell lung cancer (NSCLC) (HR=1.192, 95%CI: 1.061-1.399; Pheterogeneity=0.003) as well as small cell lung cancer (SCLC) (HR=1.550, 95% CI: 1.156-2.077; Pheterogeneity=0.625) in multivariate studies. The synthesized evidence from this meta-analysis of published articles demonstrated that an elevated neutrophil to lymphocyte ratio was a predictor of poor overall survival in patients with lung cancer. .

Ratio of monocytes to lymphocytes in peripheral blood in patients diagnosed with active tuberculosis

Objective: The ratio of monocytes to lymphocytes in peripheral blood could reflect an indi- vidual's immunity to Mycobacterium tuberculosis. The objective of this study was to evaluate the relationship between ratio of monocytes to lymphocytes and clinical status of patients with active tuberculosis. Methods: This was a retrospective review of data collected from the clinical database of The Fifth People's Hospital of Wuxi, Medical College of Jiangnan University. A total of 419 patients who had newly diagnosed active tuberculosis and 108 cases from 419 patients with tuberculosis therapy either near completion or completed were selected. Controls were 327 healthy donors. Results: Median ratio of monocytes to lymphocytes was 0.36 (IQR, 0.22-0.54) in patients before treatment, and 0.16 (IQR, 0.12-0.20) in controls (p < 0.001). Ratio of monocytes to lymphocytes <9% or >25% was significant predictors for active tuberculosis (OR = 114.73, 95% CI, 39.80-330.71; OR = 89.81, 95% CI, 53.18-151.68, respectively). After treatment, the median ratio of monocytes to lymphocytes recovered to be nearly normal. Compared to other patients, patients with extrapulmonary tuberculosis and of age >60 years were more likely to have extreme ratio of monocytes to lymphocytes (AOR = 2.57, 95% CI, 1.08-6.09; AOR = 4.36, 95% CI, 1.43-13.29, respectively). Conclusions: Ratio of monocytes to lymphocytes <9% or >25% is predictive of active tuberculosis. .

Tracheal reconstruction with memory alloy prosthesis coated with collagen / 中国医疗器械杂志

<p><b>OBJECTIVE</b>To investigate the feasibility of tracheal reconstruction with a prosthesis made of memory alloy coated with collagen sponge in mongrel dogs.</p><p><b>METHOD</b>The basic skeleton of the prosthesis was knitted with Ni-Ti memory alloy wires. The tubular mesh was sealed with polyurethane membrane and then inner and external walls of the lumen were coated with collagen sponge. Cervical trachea segmental reconstruction was performed in 8 mongrel dogs with these prostheses. The efficacy of the implanted prostheses were periodically evaluated after operation using x-ray, tracheoscopy and specimen microscope examinations.</p><p><b>RESULTS</b>One dog died of prosthesis dislocation 10 days after operation, another was killed 45 days later because of anastomotic stenosis. 6 dogs survived more than 90 days and the longest one lived for 150 days. Its implanted prosthesis was completely incorporated with the recipient tissue, where re-epithelialization occluded on anastomotic sites. The tracheal lumen was patent.</p><p><b>CONCLUSION</b>This memory alloy tracheal prosthesis has been proved useful for reconstruction of large, circumferential tracheal defects, although its long-term safety and efficiency need to be confirmed.</p>
