Molecular targeted therapy has become an emerging promising strategy in cancer treatment, and screening the agents targeting at cancer cell specific targets is very desirable for cancer treatment. Our previous study firstly found that a secretory peroxidase of class III derived from foxtail millet bran (FMBP) exhibited excellent targeting anti-colorectal cancer (CRC) activity in vivo and in vitro, whereas its underlying target remains unclear. The highlight of present study focuses on the finding that cell surface glucose-regulated protein 78 (csGRP78) abnormally located on CRC is positively correlated with the anti-CRC effects of FMBP, indicating it serves as a potential target of FMBP against CRC. Further, we demonstrated that the combination of FMBP with the nucleotide binding domain (NBD) of csGRP78 interfered with the downstream activation of signal transducer and activator of transcription 3 (STAT3) in CRC cells, thus promoting the intracellular accumulation of reactive oxygen species (ROS) and cell grown inhibition. These phenomena were further confirmed in nude mice tumor model. Collectively, our study highlights csGRP78 acts as an underlying target of FMBP against CRC, uncovering the clinical potential of FMBP as a targeted agent for CRC in the future.

Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.

AIM: To explore the promoting effect of 2-APB on skin wound healing in mice and its potential mechanism. METHODS: KM mice were divided into 5 groups: control group, DMSO group, low (50 mg/L), medium (100 mg/L) and high (200 mg/L) concentration 2-APB group. On the back of each mouse's skin use a circular punch about 1 cm on both sides of the midline of the spine to make a skin wound with a diameter of 10 mm and as deep as the fascia. The control group was only wrapped with gauze and no drugs were applied; the DMSO group was applied 1 g DMSO/Vaseline ointment per day; in the 2-APB group, apply 1 g of 2-APB/Vaseline ointment at a corresponding concentration every day. Pictures were taken the next day to observe the healing, and the material was taken on the 21st day, HE staining was used to observe the pathological morphology of the wound and western blot to detect TRPM7, TGF-β, collagen-I and IL-1β expression. RESULTS: Compared with the control group and the DMSO group, different concentrations of 2-APB could significantly promote skin wound healing in mice (P<0.01), but there was no significant difference in wound healing rate between the DMSO group and the control group group. The results of HE staining showed that, compared with the control group group and the DMSO group, 2-APB could increase the collagen content of the wound and the thickness of the dermis (P<0.01), but there was no significant difference between the DMSO group and the control group group. At the same time, 2-APB could also significantly increase the expression of TGF-β and Col-I on the wound, and inhibit the expression of TRPM7 and IL-1β. CONCLUSION: Different concentrations of 2-APB (50, 100 and 200 mg/L) can promote skin wound healing, and its mechanism may be related to the inhibition of TRPM7.

Objective To observe the effect of hyperbaric oxygen (HBO) therapy combined with repeated transcranial magnetic stimulation (rTMS) on patients with cognitive dysfunction after cerebral infarction.Methods A total of 81 patients with cognitive dysfunction after cerebral infarction were randomly divided into a control group,an HBO group and a combined treatment group,each of 27.In addition to basic medication and traditional rehabilitation therapy,the HBO group was also treated with hyperbaric oxygen,while the combined treatment group received both HBO and rTMS.The mini-mental state examination (MMSE) and the Montreal cognitive assessment (MoCA) were administered before and after the four weeks of treatment.Results The average MMSE scores of the HBO and combined treatment groups were both significantly higher than that of the control group,with the former significantly higher than the latter.Moreover,the average MoCA score of the HBO group was also significantly higher than that of the combined treatment group,and both were significantly higher than that of the control group.Conclusion Hyperbaric oxygen therapy can more effectively improve the cognitive function of patients with cognitive dysfunction after the cerebral infarction when it is combined with repeated transcranial magnetic stimulation.

OBJECTIVE To investigate and analysis of hearing status and characteristics of China civil aviation air traffic controllers(ATC). METHODS With cluster random sampling, air conduction threshold data of 1498 ATC, who had finished the class Ⅲa medical assessment this year in a certain area were studied. The subjects were tested by pure tone audiometry, the prevalence rate of speech and high frequency hearing loss between gender groups were compared; After age correction, the threshold of different frequencies were compared between age groups. RESULTS The prevalence rate of hearing loss at speech frequency was 6.68％ in male and 1.97％ in female. The result of high frequency was 7.87％ and 1.23％ respectively. Both the threshold and prevalence rate of hearing loss of every frequency were higher in male(P<0.05); The threshold of 3000 Hz

Objective To investigate the application of peripheral perfusion index (PPI) in early diagnosis and goal-directed therapy of septic shock, and to provide reference for the early clinical diagnosis and treatment of septic shock. Methods A prospective single-blind randomized controlled trial (RCT) was conducted. Adult patients with sepsis admitted to emergency medical department and intensive care unit (ICU) of the First People's Hospital of Lianyungang City in Jiangsu Province from January 2013 to December 2016 were enrolled. The patients were randomly divided into two groups (n = 46). The PPI group was defined using PPI < 1.4 as diagnosis of septic shock standard, and PPI > 2 as treatment guide target. Control group was defined according to the traditional diagnostic criteria of shock which systolic blood pressure was less than 90 mmHg (1 mmHg = 0.133 kPa) or systolic blood pressure value decrease> 40 mmHg baseline and bundle treatment was performed. The volume of fluid resuscitation, organ dysfunction, the sequential organ failure score (SOFA), acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score,continuous renal replacement therapy (CRRT) time, mechanical ventilation (MV) time, the length of ICU stay and 28-day mortality were observed. Results There were 39 and 27 septic shock patients in PPI group and control group respectively. The diagnostic criteria of traditional septic shock with blood pressure as "gold standard", the sensitivity of PPI < 1.4 for septic shock was 94.3%, the specificity was 28.2%, the authenticity was 66.3%, the positive predictive value was 64.1%, the negative predictive value was 78.6%, the positive likelihood ratio was 1.31, the negative likelihood ratio was 0.18. The per capita fluid replacement within 24 hours in the PPI group was significantly higher than that in the control group (mL: 4 601±1 250 vs. 3 458±1 006, P < 0.01), but there was no significant difference in the per capita volume of the patients diagnosed as septic shock (mL: 4 596±1 320 vs. 4 205±1 058, P > 0.05). Compared with the control group, the PPI group treated patients within 48 hours with less vascular active drugs (cases: 6 vs. 15), APACHE Ⅱand SOFA score were lower (48 hours: APACHE Ⅱ was 10.2±2.1 vs. 12.0±3.2; 72 hours: SOFA was 5.1±1.8 vs. 6.0±2.1, APACHE Ⅱ was 8.9±1.8 vs. 9.8±2.2), the period of CRRT and the length of ICU stay were shorter [the period of CRRT (days): 3.0±0.9 vs. 3.6±1.4, the length of ICU stay (days): 5.2±2.1 vs. 6.3±2.9), the difference was statistically significant (all P < 0.05). There was no significant difference in the liver and kidney function index, arterial blood lactic acid (Lac), MV time (days: 3.3±1.4 vs. 3.5±1.2) and 28-day mortality (15.22% vs. 19.57%) between two groups (all P > 0.05). Conclusions The inadequacy of microcirculatory perfusion by oximetry-derived PPI is more sensitive to the diagnosis of septic shock than hypotension of systemic circulation. With PPI guiding the fluid resuscitation of septic shock patients, vasopressors can be withdrawn earlier and the duration of the CRRT and ICU can be decreased.

Objective To study extended high frequency (EHF) audiometry for early detection of hearing loss in student pilots in civil aviation.Methods A total of 175 student pilots (all male,18~25 years old, mean 20.2±0.92 years) from a university flight academy were surveyed and underwent EHFA.All subjects had hearing thresholds ≤25 dB HL at conventional frequencies (0.25~8 kHz).The results were compared with the corresponding recommended standards in other countries.According to the use of personal listening devices, all the subjects were divided into the low risk group (non-use, 121 cases) and the high risk group (using>1 year, day>1 hour, 52 cases).The differences of hearing thresholds and detection rates at EHF between the two groups were compared.Results The hearing thresholds of 173 subjects (1 case of middle ear disease and 1 case with family history of hearing loss were excluded) at 9~20 kHz were slightly higher than the reference equivalent threshold sound pressure level (RETSPL) prescribed by American National Standardization Association and the age-matched thresholds recommended by a foreign literature (P<0.05 or P<0.01).The hearing thresholds in the high risk group elevated dramatically than that in the low risk group at 9,12.5,16 and 18 kHz(P<0.05 or P<0.01).As frequencies increased, the detection rate of hearing thresholds in the high risk group decreased gradually, and at 18 and 20 kHz it was significantly lower than that in the low risk group (P<0.01).Conclusion EHF audiometry is a helpful tool for early detection of noise-induced hearing loss in student pilots.Hearing health care should be emphasized in civilian student pilots.It is recommended to avoid the use of personal listening devices or reduce the use time of them.

Objective To report 1 case with renal immunoglobulin light and heavy chain deposited disease (IgG-κ light chain and γ1 heavy chain).Methods The clinical manifestations,serum immunofixation electrophoresis,light and heavy chain abnormalities of blood and urine,bone marrow biopsy and renal biopsy data laboratory data were recorded and analyzed.Results A 63-year-old woman presented with massive proteinuria,microscopic hematuria,hypertension,anemia and serum IgG-κ light chain.Bone marrow aspirate revealed 4％ plasma cells.Renal biopsy revealed nodular glomerulopathy with congo red staining-negative.Immunofluorescence showed that κ light chain and IgG1 (γ1 heavy chain) were deposited along the glomerular basement membranes (GBM) and tubular basement membranes (TBM).Electron-microscopy revealed electrondense deposits that delineate the outer aspect of TBM and endothelial aspect of GBM.Conclusion The diagnosis of renal immunoglobulin light and heavy chain deposited disease (IgG-κ light chain and γ1 heavy chain) should be addressed combine with clinical and is pathology,especially with immune pathological examination.

Methods Seventy-six cases of DVT after cesarean were randomly divided into 2 groups. Thirty-six cases of control group were injected low molecular weight heparin calcium subcutaneously 100 AXaIU/kg twice daily, and forty cases of treatment group were treated with Buyang Huanwu Decoction additionally. After analysing the clinical symptoms and sign before and after treatment, HBV, LBV, PV, FIB, PLT, APTT, TT, PT and indexes of impedance plethysmography, CDFI were observed to evaluate the efficacy. Results After treatment, the total effective rate of treatment group was 97.5%(39/40), and the control group was 77.8%(28/36), the difference was statistically significant (P<0.05). The differences of hemorheological indexes (HBV, LBV, PV, FIB) and impedance plethysmography indexes between before and after treatment in treatment group were statistically significant (P<0.05), while the differences of blood coagulation indexes (APTT, TT, PT) were not significant (P>0.05). No adverse reaction was found during treatment. Conclusion The treatment of DVT after cesarean section with Buyang Huanwu Decoction combined with low molecular weight heparin calcium injection is safe and effective.

In this study we used two types of cell cultures, i.e., anchorage-dependent basket and full suspension batch cultures of sTNFRII-gAD-expressing CHO cells in the CelliGen 310 bioreactor (7.5 L) to compare their yields in order to optimize the culturing conditions for efficient expression of sTNFRII-gAD fusion protein consisting of soluble tumor necrosis factor receptor II and globular domain of adiponectin. The anchorage-dependent basket culture was performed in 4L 10% serum-containing medium with the final inoculating concentration of 3 x 10(5) to 4 x 10(5) cells/mL of sTNFRII-gAD-expressing CHO cells for 3 days, and then switched to 4 L serum-free LK021 medium to continue the culture for 4 days. The full suspension batch culture was carried out in the 4 L serum-free LK021 medium with the final inoculating concentration of 3 x 10(5) to 4 x 10(5) cells/mL of sTNFRII-gAD-expressing CHO cells for 7 days. The culturing conditions were monitored in real-time to maintain pH and dissolved oxygen stability through the whole process. The supernatants were collected by centrifuge, and the protein was concentrated through Pellicon flow ultrafiltration system and then purified by DEAE anion exchange. The results showed that the yields of sTNFRII-gAD fusion protein were 8.0 mg/L with 95% purity and 7.5 mg/L with 98% purity in the anchorage-dependent basket and the full suspension batch cultures, respectively. The study provided the framework for the pilot production of sTNFRII-gAD fusion protein.
