Objective To learn the management staff and funds allocation of the NRCMS in Guangxi,and come up with solution accordingly.Methods Collection of the annual report data of NRCMS in Guangxi from 2009 to 2012,and calculation of the management personnel and funds expenditure.Results The management personnel of NRCMS in Guangxi is found with a 1000-person gap between the actual staffing and approved staffing quota; the management funds rise year by year which come mostly from fiscal appropriation.Yet it accounts for less than 2.00％ and with a high rate of surplus; per-capita funds for management personnel rise significantly,along with their per-capital salaries,yet the highest fall below 25000 yuan per year per person.Conclusion Staffing quota should be fixed more rationally to ensure the number and competence of NRCMS management staff; more funds and better use of management funds are required.

This study was to investigate the protective effects of puerarin on myocardial ischemia/reperfusion (MI/R) injury and the underlying mechanism. The MI/R-model was established by ligating the left anterior descending artery (LAD) for 60 min followed by 24 h reperfusion, puerarin (10, 30, and 100 mg·kg^-1) was orally administered 20 min before reperfusion. Cardiac function, myocardial infarct index, cardiac damage markers, inflammatory cytokines, and apoptosis index were measured to evaluate the protective effects of puerarin on MI/R injury. The activation of Nod-like receptor protein 3 (NLRP3) inflammasome and Toll like receptor 4 (TLR4)/myeloid differentiation factor 88 (Myd88)/nuclear factor kappa B (NF-κB) pathway were determined by Western blot. All animal experimental procedures were approved by the ethics committee of the Institute of Materia Medica, Peking Union Medical College, Chinese Academy of Medical Sciences. The results showed that puerarin could significantly improve cardiac function, reduce myocardial infarct size, decease the levels of lactic dehydrogenase (LDH), aspartate transaminase (AST), creatine kinase-MB (CK-MB), and cardiac troponin T (cTnT) and suppress cardiomyocyte apoptosis. Meanwhile, puerarin could notably decrease the levels of inflammatory cytokines such as interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis revealed that puerarin could downregulate the expression of TLR4, Myd88, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cleaved-caspase 1, cleaved-gasdermin-D (GSDMD), IL-1β, and IL-18, as well as the phosphorylation levels of inhibitor of NF-κB α (IκBα), IκB kinase β (IKKβ), and NF-κB. These findings demonstrated that puerarin could alleviate MI/R injury by suppressing NLRP3 inflammasome activation, possibly via TLR4/Myd88/NF-κB pathway.

Objective To investigate the endoscopic and pathological characteristics of Barrett's esophagus (BE).Methods Data of 152 patients who were diagnosed as having BE with endoscopy and pathology were retrospectively analyzed.Results BE was most commonly seen in patients of 40-60 years old.The clinical manifestations overlapped in different patients,including regurgitation and heartburn in 78 (51.32%),dysphagia in 9 (5.92%),retrosternal pain in 12 (7.89%),upper abdominal pain or discomfort in 67 (44.08%),and asymptomatic in 8 (5.26%).Long segment BE (LSBE) was determined in 7 patients (4.61%),and short segment BE (SSBE) in 145 (95.39%).The metaplasia pattern under endoscopy included island like in 98 (64.47%),tongue like in 39 (25.66%) and circumferential in 15 (9.87%).Stratified squamous epithelia in the lower part of the esophagus were replaced by columnar epithelia in all cases,and intestinal metaplasia occurred in 68 cases (44.74 %).Conclusion BE is most frequently seen in the middle-aged and can be diagnosed by endoscopy and pathology without special clinical manifestations.Island pattern occurs in most cases and is with lowest rate of intestinal metaplasia,which is associated with age.Patients with specialized intestinal metaplasia and dysplasia should be followed up for surveillance of cancer.

OBJECTIVETo explore treatment methods for patients with severe aplastic anemia (SAA) failing in immunosuppressive therapy (IST).

METHODSTotally 62 SAA patients failing in IST were treated by integrative medicine (IM). The treatment course was divided into three stages: the critical emergency stage, the improvement stage, and the recovery stage. In the critical emergency stage, patients were treated with Lingyang Yigui Decoction (LYD, consisting of 1.2 g antelope horn, 6 g coptis chinensis, 12 g stir-baked Fructus Gardeniae, 30 g rehmannia rhizoma, 50 g lalang grass rhizome, 9 g amur corktree bark, 12 g Cortex Moutan, 9 g ass-hide gelatin, 30 g red date, 6 g prepared licorice root, etc.) and Erzhi Busui Decoction (EBD, consisting of 120 g glossy privet fruit, 100 g eclipta prostrata, 24 g prepared Gold Theragran, 12 g fructus lycii, 90 g rehmannia rhizoma, 60 g astragalus, 9 g Angelica sinensis, 9 g ass-hide gelatin, 30 g honeysuckle flower, 12 g lotus plumule, and so on) alternatively, one dose daily, decocted twice, taken in two portions. Meanwhile, 50 mg Testosterone Propionate was intramuscularly injected every other day to the improvement stage. Those with fever were treated with LYD by adding 60 g gypsum, 60 g common anemarrhena, 30 g dandelion, 30 g bittersweet herb, 30 g blackend swallowwort root and rhizome, 15 g hemsley rockvine root tuber, and so on. In the improvement stage patients were treated with Jixueteng Compound (Jixueteng Zhengyang Decoction was administered to those of Shen-yang deficiency syndrome: consisting of 100 g spatholobus suberectus, 60 g astragalus, 3 g red ginseng, 12 g psoralea corylifolia, 18 g dodder seed, 12 g angelica, 18 g Herba Epimedii, 6 g common fenugreek seed, 24 g Gold Theragran, 30 g glossy privet fruit, 30 g eclipta prostrata, 6 g dried human placenta, and so on). Meanwhile, 50 mg Testosterone Propionate was intramuscularly injected every other day. Jixueteng Yijing Decoction was administered to those of Shen-yin deficiency syndrome: consisting of 100 g glossy privet fruit, 100 g eclipta prostrata, 90 g rehmannia rhizoma, 30 g spatholobus suberectus, 12 g dodder seed, 6 g psoralea corylifolia, 30 g prepared Gold Theragran, 9 g ass-hide gelatin, 9 g fructus lycii, 24 g Salvia miltiorrhiza, 30 g astragalus, 6 g angelica, and so on), one dose daily, decocted twice, taken in two portions. The treatment lasted to the recovery stage. The medication was gradually reduced to the follow-ups of drug discontinuance. Results After 6 -57 months of treatment, 12 patients (accounting for 19.4%) were basically cured, 14 (22.6%) relieved, 8 (12. 9%) markedly improved, 28 (45.2%) ineffectively, with the total effective rate of 54. 8%. Totally 23 patients had the body temperature ranging 37.6-38.5 degrees C at the first visit to our hospital. They took 2 h- 6 days to have pyretolysis ( <37.5 degrees C) after treatment. Twenty patients with body temperature higher than 38.5 degrees C took 4 h - 5 days to have pyretolysis after treatment. Totally 26 patients suffering from IST induced abnormalities of liver and renal functions (ALT, AST, BUN, and Cr) at the first visit were treated by IM for 2 months. They were restored to the normal levels in 25 cases.

CONCLUSIONSThe treatment of SAA failing in IST had its specificity. The staging targeted treatment is in line with its pathophysiology. The key points for its treatment might be lie in the improvement and protection of hematopoietic microenvironment of bone marrows. The antisepsis and anti-inflammation of Chinese herbs hindered its aggravating tendency.

Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

Objective To evaluate the value of endobronchial ultrasound elastography in diagnosis of mediastinal lymph nodes by measuring the parameters of endobronchial ultrasound elastography. Methods Between 2016 and 2017, 46 patients with 63 lesions underwent EBUS-TBNA examination were included. Conventional ultrasound and ultrasound elastography were performed respectively to examine 63 lymph nodes before aspiration. Then various features of conventional ultrasound and parameters of ultrasound elastography were analyzed and recorded. Then evaluate the value of ultrasound elastography by pathological results and three-month follow-up data. Result The diagnostic value of ultrasound elastography image type, elasticity score, strain ratio and blue area ratio for malignant lymph nodes were higher than that of conventional ultrasound features in accuracy, sensitivity and specificity (P < 0.05); The accuracy of the boundary was the highest in the diagnosis of malignant lymph nodes. In the ultrasound elastography parameters, the accuracy of the elasticity score was the highest, and the blue area ratio had the largest area under the curve. When the boundary was used as the joint index to judge malignant lymph nodes with elasticity score and area ratio respectively, significantly higher than the diagnostic accuracy of conventional ultrasound and ultrasound elastography alone (P < 0.05). Conclusion The value of ultrasound elastography parameter in mediastinal lymph nodes diagnosis is higher than the conventional ultrasound features and a combination of both applications can improve discrimination accuracy of benign and malignant lymph nodes.
