AIM: To investigate the refractive distribution and analysis risk factors for aircrew ametropia.
METHODS: The number of 49 cases with ametropia from 1031 aircrew during May 2013 to May 2014 were reviewed. Various types of refraction composition, age, type, position, time of flight with the subjective assessment of aircrew were analyzed and compared.
RESULTS:Of 49 cases, 43 cases (88%) were myopia, 6 cases ( 12%) were hypermetropia. , Detection rates were higher in age over 50 years aircrew and flight time more than 3000h. Detection rates were lower in self-conscious symptom heavy aircrew, fighter aircrew and good habit of using eyes.
CONCLUSION: The myopia incidence in aircrew with age >50 years and long flight time is higher, than that of fighter pilots and good habit of using eyes. We should pay attention to the increasing late-onset myopia of aviators and habit of using eyes, work intensity and time of using eyes about aircrew.

Objective To screen the differential proteins in the brain (neocortex and hippocampus) between the rats with cortical dysplasia (CD) and control ones,and investigate the role of their alteration in the development of epilepsy in CD.Methods Cortical dysplasia was induced in rat pups via in utero delivery of BCNU.A two-dimensional electrophoresis (2-DE)-based approach was used to construct the expression profiles of proteins in both the neocortex and hippocampus at different age groups (postnatal day 7 and 60) and to detect proteome changes between CD rats and control ones.Following gel image analysis,protein spots that differed in abundance between CD and control rats were identified by using Matrx-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) and MS/MS.Results A total of 57 kinds of protein were screened out (P ＜ 0.05),in which 35 were found up-regulated and 22 were down-regulated compared with the control,35 from neonatal stage (postnatal day 7) and others from adult stage.Finally,12 among them were identified,including tubulin,alpha-lB,Beta-actin,tubulin beta-2A,GAP-43,UbCKmit,GAPDH and TMBr-3,etc.Conclusions Changed expression of specific proteins which were found in our study are involved in construction of brain 's cytoskeleton,synaptic function,mitochondrial function and so forth.Thus,they may be related to the pathogenic mechanisms of epileptogenicity of CD.

The epidemic of COVID-19 has brought great challenges to the global public health prevention and control system combined with clinical diagnosis and treatment system, and it makes the development of effective antiviral drugs an important task in current pharmaceutical research. Traditional Chinese medicine (TCM) has played an important role in the prevention and control of COVID-19. Due to its numerous chemical components and various structural types, TCM becomes a natural library for searching for lead compounds against SARS-CoV-2. In this study, a novel dual-target surface plasmon resonance (SPR) biosensor was developed for S protein receptor binding domain (SRBD) and angiotensin converting enzyme 2 (ACE2) which are two key proteins in the process of SARS-CoV-2 invading cells according to characteristics of synergistic effects of multiple components and comprehensive regulation of multiple targets of TCM. The SPR biosensor was applied to screen and identify active components from six TCMs, and daidzin from Puerariae Lobatae Radix was identified to bind with SRBD and ACE2. The affinity constant (K_D) of daidzin and ACE2 was 5.18 μmol·L^-1 through the SPR affinity assay. Competitive ELISA assay showed that daidzin could inhibit the binding of SRBD and ACE2, and the inhibition rate of daidzin (20 μmol·L^-1) was 38.6%. Molecular docking experiments further confirmed that daidzin had the best binding near the binding region of SRBD-ACE2 complex. This study shows that the dual-target SPR screening system is accurate and efficient, and is particularly suitable for screening of complex drug systems and effective substances study of TCM. It provides a material basis for exploring the mechanism of TCM active constituents against SARS-CoV-2, and provides a source of lead compounds for the development of anti-SARS-CoV-2 drugs.

Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

BACKGROUND:Muscle atrophy and weakness exist around the knee joint of patients with knee osteoarthritis, comprehensive treatment combined with training muscle power around knee joint can obviously relieve symptoms and restore muscle power around the knee joint.
OBJECTIVE:To test the relationship between muscle function around the knee joint and the knee joint function with isokinetic muscle strength test before and after comprehensive treatment of knee osteoarthritis, and to investigate the pathological mechanisms of knee osteoarthritis in order to provide basis for the clinical rehabilitation and treatment.
METHODS:We screened out 30 subjects with unilateral knee osteoarthritis (stage Ⅱ and Ⅲ). Hospital for Special Surgery was used to evaluate the knee function, and visual analogue scale score was used to assess the patient pain. The knee muscle function of knee osteoarthritis patients was measured before treatment;the patients with knee osteoarthritis at stage Ⅱ and Ⅲ received comprehensive treatment for at least 1 month (active quadriceps isometric muscle strengthening exercises, oral celecoxib capsules combined with intra-articular injection of sodium hyaluronate), and knee muscle function was measured after treatment. Hospital for Special Surgery and the visual analogue scale score were evaluated during fol ow-up period.
RESULTS AND CONCLUSION:Compared with the healthy side, the muscle power of the affected side of the patients with knee osteoarthritis was decreased when the flexion and extension muscle peak torque and work volume tested at 60 (°)/s and 180 (°)/s (P<0.05). After comprehensive treatment, the Hospital for Special Surgery scores of the knee osteoarthritis patients were increased significantly (P<0.05), while the visual analogue scale scores were decreased (P<0.05), and the muscle power of the affected side was increased significantly (P<0.05);there was no significant difference in the muscle power
between affected side and healthy side after treatment (P>0.05). There was no significant difference in the peak torque ratio of quadriceps and hamstring measured at 60 (°)/s in the knee osteoarthritis patients before and after treatment (P>0.05), and there was significant difference measured at 180 (°)/s (P<0.05). Knee osteoarthritis patients have decreased muscle strength around the knee joint, and the comprehensive treatment of muscle functional training combined with effective pain relief and nutrition joint drugs can significantly relieve symptoms, improve muscle strength and restore knee function.

Objective To explore the application and assess the cosmetic effect of mammaplasty with volume-displacement technique(VDT)following breast conserving surgery.Methods Breast conservation therapy(BCT) was performed in 77 patients of early breast cancer(EBC).Of the patients,42 cases received oncoplastic VDT (onco-plastic group)and 35 cases had only direct skin closure without treatment of the postresection defect (regular group) following BCT.The cosmetic results of the two groups were evaluated after operation and radiotherapy,respectively. Results All patients were followed up for 1 -36 months with median follow -up of 22.3 months,and no recurrence or metastasis occurred in one of the patients.1 month after surgery,the excellent or good cosmetic outcome were achieved in 31 cases (73.81%)in oncoplastic group and 17 cases (48.57%)in regular group respectively,and there was statistical difference between the two groups (χ2 =5.442,P =0.021);1 month after radiotherapy,the cos-metic excellent or good result were obtained in 27 cases (64.29%)in oncoplastic group and 6 cases (17.14%)in regular group respectively,and the difference between the two groups reached statistical significance (χ2 =9.045,P =0.008).Conclusion VDT can improve the cosmetic effect of mammaplasty following BCT in EBC and does not affect curative effect,it is worthy of promoting.

Objective · To detect the vitamin D2 and D3 levels in the patients with moderate and severe depression. Methods · Eighty-five patientswho met the criteria for major depressive disorder were recruited (53 patients with moderate depression, 32 patients with severe depression). Fifty agematchedhealthy volunteers were recruited as controls. Serum 25 (OH) D2, 25 (OH) D3 and total 25 (OH) D2/D3 levels were detected by using liquidchromatography-tandem mass spectrometry (LC-MS/MS). The risk factors which might influence the severity of depression were screened by Logisticregression analysis. Results · The serum 25 (OH) D2, 25 (OH) D3 and total 25 (OH) D2/D3 levels in the case group was lower than those in the controlgroup (P=0.012, P=0.000, P=0.000). The patients with moderate depression presented significantly lower serum 25 (OH) D3 and total 25 (OH) D2/D3 levelsthan the controls did (P=0.000), although no significant difference in serum 25 (OH) D2 levels was found between these two groups. As well, the serum 25 (OH) D2, 25 (OH) D3 and total 25 (OH) D2/D3 levels in patients with severe depression were significantly lower than those in patients with moderate depression and controls (P<0.05). The body mass index of severe depression group was much higher than that of moderate depression group and control group (P=0.002). Both overweight/obesity and the concentration of vitamin D may be the major influencing factors of depression severity (P=0.034, P=0.011). Conclusion · Vitamin D2 and D3 deficiency in depressive patients, particularly in those patients with severe depression, was shown in the present study. In addition, overweight/obesity as well as the concentration of vitamin D may exert the significant influence on the severity of depression. Vitamin D supplementation and weight control may be needed to be considered in making therapeutic strategies of major depressive disorder.
