Background： Malnutrition and tuberculosis （TB） tend to interact with each other. TB may lead to nutrition deficiencies that will conversely delay recovery by depressing immune functions. Nutrition support can promote recovery in the subject being treated for TB. The aim of this study was to evaluate the effectiveness of nutrition support on promoting the recovery of adult pulmonary TB patients with anti-TB drug therapy. Methods： English database of the Cocbrane Controlled Trials Register, PubMed, EMBASE, and Chinese database ofCBM, CNKI, VIE and WAN FANG were searched. Randomized controlled trials comparing nutrition support （given tbr more than 2 weeks） with no nutrition intervention, nutrition advice only, or placebo-control for TB patients being anti-TB treated were included. Two reviewers conducted data extraction, assessed the quality of the studies independently, and any discrepancies were solved by the third reviewer. Data were entered and analyzed by RevMan 5.2 software, and recta-analysis was done using risk ratios （RRs） for dichotomous variables and mean differences （MDs） for continuous variables with 95% confidence intervals （C/s）. Results： A total of 19 studies （3681 participants） were included. In nutritional support for TB patients, pooled RR and its 95% CI of sputum smears- or culture-negative conversion rate and chest X-ray （CXR） absorption rate were 1.10 （1.04, 1.17） and 1.22 （1.08, 1.39）, respectively, the pooled MD and its 95% CI of body mass index （BMI） and time of sputum smears or culture negativity were 0.59 （0.16, 1.2） and - 5.42 （-7.93, -2.92）, respectively, compared with the control group. The differences in outcomes of CXR zone affected, TB score, serum albumin, and hemoglobin were not statistically significant （P = 0.76, 0.24, 0.28, and 0.20, respectively） between the intervention group and the control group. No systemic adverse events were recorded. Conclusions： During anti-TB course, nutrition support may be helpful in treatment of TB pa

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.
