To study in a systematic and dynamic manner the level, traits, and development tracks of scientific and technological achievements in medicine and health and related disciplinary fields in the past two decades, the paper conducted a statistical analysis of the winners of prizes awarded by the Ministry of Health for progress in science and technology from 1981 to 1999. The results showed that the number of prize winners presented the tendency of fluctuating increase with 4 to 5 years as a cycle; the quality of prize winners presented a downward tendency; and endocrinology, preclinical medicine, oncology and preventive medicine ranked in the first four places with their prize winners accounting for over half of the total. The academies of medical sciences, Shanghai Medical University, Shanghai, Beijing Medical University, Beijing, and the academies of preventive medical sciences won the most prizes in almost all the fields involved while the academies of medical sciences took the first place in one third of the disciplinary fields. The project index of institutions was 1.91. The study indicates the following musts: enhancing the quality of the bidding projects, reinforcing the strength of research, and implementing policies that favor key and brainstorm projects and key disciplines; supporting weak disciplines, intensifying the development of disciplines with unique features, and stepping up scientific cooperation; strengthening scientific and technological input and the construction of echelons of scientific and technological personnel and maintaining the continuity of research contingents and capabilities of various disciplinary fields.

Lesion was made individually to the various cortical areas in 14 rats.The cortico- fugal fibers terminating into cochlear nuclei were traced in sections by means of the modified Nauta and Fink-Heimer silver staining method.The results were as follows: 1.After damaging the auditory area or somato-sensory area 1(SI)of the cerebral cortex unilaterally,degenerating fibers were found bilaterally in the ventral and dorsal cochlear nuclei.This result showed that the above cortical areas have direct descending connection with the cochlear nuclei. 2.No degenerating fibers were found in the cochlear nuclei after the ablation of the motor or visual area of the cerebral cortex,which demonstrated that the cochlear nuclei do not receive descending fibers from the above cortical areas. 3.The pathway from the cerebral cortex to the cochlear nuclei was:The descending fibers which originated from the auditory area or SI area ipsilaterally passed through the capsula interna and basis pedunculi,and part of these fibers passed dorsally and downward to the lateral portion of the reticular formation of the midbrain;and from there the fibers passed through the lemniscus lateralis and dorsal acustic stria to the cochlear nuclei of the ipsilateral side.The cochlear nuclei in contralateral side also received the corticofugal fibers by way of the dorsal acustic stria.These fibers might cross to the contralateral side at the region in the posterior commissure,superior colliculus commissure and inferior colliculus commissure.

Objective To compare the sedation and anti-inflammatory effects of dexmedetomidine and midazolam on critical ill children with multiple trauma. Methods A prospective randomized controlled trial was conducted. Sixty-five critical ill children with multiple trauma admitted to pediatric intensive care unit (PICU) of Anhui Province Children's Hospital from January 2014 to September 2016 were enrolled, who were randomly divided into dexmedetomidine group (33 cases) and midazolam group (32 cases). Children of both groups received sufentanil for analgesia. Children in dexmedetomidine group firstly received 1.0 μg/kg intravenous bolus of dexmedetomidine for 10 minutes, then continuous infusion of 0.2-0.7 μg·kg-1·h-1, while in midazolam group children received 1-5 μg·kg-1·min-1 of midazolam in continuous infusion. The goal of sedation was to maintain a Richmond agitation-sedation scale (RASS) score of -1 to 0. The level of serum interleukin (IL-6, IL-8, IL-10, IL-1β), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) were detected by enzyme linked immunosorbent assay (ELISA) at 24, 48, 72 hours after treatment, and the duration of mechanical ventilation, ratio of continuous renal replacement therapy (CRRT), length of stay in the PICU, ratio of sepsis and multiple organ failure (MOF) and mortality were also recorded. Results Compared with midazolam, dexmedetomidine decreased the level of pro-inflammatory cytokines and increased the level of anti-inflammatory cytokines. At 24 hours after treatment, the levels of serum IL-1β, TNF-α significantly decreased and IL-10 significantly increased [IL-1β (ng/L):6.48±2.89 vs. 8.07±3.14, TNF-α (μg/L): 11.25±5.21 vs. 15.44±5.97, IL-10 (ng/L): 12.10±5.35 vs. 9.58±4.71, all P < 0.05]. At 48 hours after treatment, the levels of serum IL-6, IL-8, IL-1β, TNF-α and CRP significantly decreased and IL-10 significantly increased [IL-6 (ng/L): 209.67±80.49 vs. 336.31±123.94, IL-8 (ng/L):229.09±80.81 vs. 298.28±90.25, IL-1β (ng/L): 7.31±3.02 vs. 8.74±3.17, TNF-α (μg/L): 12.52±4.79 vs. 16.58±5.98, CRP (g/L): 47.82±24.92 vs. 72.35±31.71, IL-10 (ng/L): 12.90±5.42 vs. 10.01±4.79, all P < 0.05]. At 72 hours after treatment, the levels of serum IL-8 and CRP significantly decreased [IL-8 (ng/L): 234.64±96.24 vs. 290.28±103.97, CRP (g/L): 53.24±29.12 vs. 86.58±38.30, both P < 0.05]. Compared with midazolam, dexmedetomidine could significantly reduce the duration of mechanical ventilation (days: 4.7±1.3 vs. 6.6±2.1), length of PICU stay (days: 9.5±2.7 vs. 12.3±3.9, both P < 0.05), and the ratio of sepsis (33.3% vs. 53.1%, P < 0.05). But there were no significant differences in ratio of CRRT (18.2% vs. 18.8%), MOF (9.1% vs. 18.8%) and mortality (6.1% vs. 12.5%) between two groups (all P > 0.05). Conclusion Compared with midazolam, dexmedetomidine had better efficacy in the treatment of severe multiple trauma in children and reduce the level of inflammation.

Objective:To evaluate the efficacy and toxicity of single-agent bendamustine in patients with indolent B-cell non-Hodgkin's lymphoma (NHL) refractory to rituximab. Methods:Between April 2010 and April 2013, 100 patients with rituximab-refrac-tory indolent B-cell NHL from 8 institutions were enrolled. Bendamustine was administered at 120 mg/m2 on days 1 and 2 every 21 days for 6-8 cycles. The primary endpoint was the overall response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results:One hundred patients with a median age of 56 (rang-ing from 28 to 74) years were recruited in this clinical study. The total number of chemotherapy was 447 cycles, and the median number was 4 cycles. Ninety-three patients could be evaluated for efficacy. Fifteen patients (16.1%) had complete remission (CR), 52 (55.9%) had partial remission (PR), 22 (23.7%) had stable disease (SD), and 4 (4.3%) had progression disease (PD). The ORR and DCR were 72%and 95.7%, respectively. After a median follow-up of 26.6 months (ranging from 2 to 48.4 months), 59 patients (63.4%) had PD.The median PFS was 8.53 (95%CI:6.518-10.542) months, and PFS rate for 1 year was (40.6±5.3)%. Forty-eight patients (48%) had 3/4 grade adverse events, including leucopenia (26%), neutropenia (24%), and anemia (11%). Conclusion:Single-agent bendamustine produced a high rate of objective responses in patients with rituximab-refractory indolent B-cell NHL and could be one of the new op-tions for second-line treatment of these patients. The most common adverse event is hematologic toxicity.

OBJECTIVE:With the popularity of simulated barefoot running,minimalist shoes have become a new way of foot exercise.As an important muscle group of the foot,the maintenance of foot muscle morphology is important for the execution of foot functions.In this paper,by combing the literature about the effect of minimalist shoes on foot muscle morphology in recent years,we systematically evaluate the effect of minimalist shoes on foot muscle morphology compared with traditional running shoes. METHODS:The relevant articles published from 2012 to 2022 were searched in Chinese and English databases(PubMed,Web of Science,ProQuest,CNKI and WanFang databases)with"minimal shoes,minimal footwear,minimalist shoes,minimalist footwear,foot muscle,feet muscle"as Chinese and English keywords,respectively.Meta-analysis,sensitivity tests were performed on the included literature using Review Manager 5.4.1 and Stata 14 software,the Egger method was used to test for publication bias in the literature,and Meta-regression was used to identify the subgroups with heterogeneity. RESULTS:Compared with traditional running shoes,minimalist shoes increased muscle circumference of the abductor hallucis[standardized mean difference=2.034,95%confidence interval(1.192,2.877),Z=4.73,P<0.001].And the results were not reversed after clipping and patching,with a more robust combined effect size(P<0.05).For the toe short flexors,the total combined effect size did not show a difference between traditional running shoes and minimalist shoes[standardized mean difference=0.470,95%confidence interval(-0.45,1.39),Z=1.00,P=0.318]. CONCLUSION:Compared with traditional running shoes,minimalist shoes intervention can effectively improve muscle circumference of the abductor hallucis,but the promoting effect on the flexor digitorum brevis muscle is not obvious.Running in minimalist shoes has positive implications for the maintenance of the medial longitudinal arch,but it is necessary to enrich the research content of minimalist shoes on different foot muscles and different populations in order to further explore the mechanisms by which minimalist shoe interventions promote foot function.

BACKGROUNDEndostar™ (rh-endostatin, YH-16) is a new recombinant human endostatin developed by Medgenn Bioengineering Co. Ltd., Yantai, Shandong, P.R.China. Pre-clinical study indicated that YH-16 could inhibit tumor endothelial cell proliferation, angiogenesis and tumor growth. Phase I and phase II studies revealed that YH-16 was effective as single agent with good tolerance in clinical use.The current study was to compare the response rate , median ti me to progression (TTP) ,clinical benefit andsafety in patients with advanced non-small cell lung cancer ( NSCLC) , who were treated with YH-16 plus vi-norelbine and cisplatin (NP) or placebo plus NP.
METHODSFour hundred and ninety-three histologically or cy-tologically confirmed stage IIIB and IV NSCLC patients , withlife expectancy > 3 months and ECOG perform-ance status 0-2 , were enrolledin a randomized ,double-blind ,placebo-controlled , multicenter trial ,either trialgroup : NP plus YH-16 (vinorelbine 25 mg/m² on day 1 and day 5 ,cisplatin 30mg/m² on days 2 to 4 , YH-167.5mg/m² on days 1 to 14) or control group : NP plus placebo (vinorelbine 25 mg/m² on day 1 and day 5 ,cis-platin 30 mg/m² on days 2 to 4 ,0.9% sodium-chloride 3 .75 ml on days 1 to 14) every 3 weeks for 2-6 cycles .The trial endpoints included response rate ,clinical benefit rate ,time to progression,quality of life and safety .
RESULTSOf 486 assessable patients , overall response rate was 35.4% in trial group and 19.5% in controlgroup (P=0 .0003) . The median TTP was 6 .3 months and 3 .6 months for trial group and control group respectively (P < 0 .001) . The clinical benefit rate was 73 .3 %in trial group and 64.0% in control group (P=0 .035) .In untreated patients of trial group and control group ,the response rate was 40 .0% and 23.9%(P=0 .003) ,the clinical benefit rate was 76 .5 % and 65 .0 % (P=0 .023) ,the median TTP was 6 .6 and 3 .7months (P=0 .0000) ,respectively .In pretreated patients of trial group and control group ,the response ratewas 23.9% and 8.5%(P=0 .034) ,the clinical benefit rate was 65.2% and 61.7%(P=0 .68) ,the median TTP was 5 .7 and 3 .2 months (P=0 .0002) ,respectively . The relief rate of clinical symptoms in trial groupwas higher than that of those in control group ,but no significance existed (P > 0 .05) . The score of quality oflife in trial group was significantly higher than that in control group (P=0 .0155) after treatment . There were no significant differences in incidence of hematologic and non-hematologic toxicity , moderate and severe sideeffects betweentrial group and control group .
CONCLUSIONSThe addition of YH-16 to NP regimen results in significantly and clinically meaningful improvement in response rate , median time to tumor progression,and clinical benefit rate compared with NP alone in advanced NSCLC patients . YH-16 in combination with chemotherapy shows a synergic activity and a favorable toxic profile in advanced cancer patients .

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.
