Abstract
Essential oils are potential alternatives to antibiotics for preventing Candida albicans (C. albicans) infection which is responsible for economic losses in the pigeon industry. Cymbopogon martini essential oil (EO) can inhibit pathogens, particularly fungal pathogens but its potential beneficial effects on C. albicans-infected pigeons remain unclear. Therefore, we investigated the impact of C. martini EO on antioxidant activity, immune response, intestinal barrier function, and intestinal microbiota in C. albicans-infected pigeons. The pigeons were divided into four groups as follows: (1) NC group: C. albicans uninfected/C. martini EO untreated group; (2) PC group: C. albicans infected/C. martini EO untreated group; (3) LPA group: C. albicans infected/1% C. martini EO treated group; and (4) HPA group: C. albicans infected/2% C. martini EO treated group. The pigeons were infected with C. albicans from day of age 35 to 41 and treated with C. martini EO from day of age 42 to 44, with samples collected on day of age 45 for analysis. The results demonstrated that C. martini EO prevented the reduction in the antioxidant enzymes SOD and GSH-Px causes by C. albicans challenge in pigeons. Furthermore, C. martini EO could decrease the relative expression of IL-1β, TGF-β, and IL-8 in the ileum, as well as IL-1β and IL-8 in the crop, while increasing the relative expression of Claudin-1 in the ileum and the crop and Occludin in the ileum in infected pigeons. Although the gut microbiota composition was not significantly affected by C. martini EO, 2% C. martini EO increased the abundance of Alistipes and Pedobacter. In conclusion, the application of 2% C. martini EO not only enhanced the level of antioxidant activity and the expression of genes related to intestinal barrier function but also inhibited inflammatory genes in C. albicans-infected pigeons and increased the abundance of gut bacteria that are resistant to C. albicans.

Abstract
Objective: To clarify the mechanisms involvement in Alisertib-resistant colorectal cells and explore a potential target to overcome Alisertib-resistance. Methods: Drug-resistant colon cancer cell line (named as HCT-8-7T cells) was established and transplanted into immunodeficient mice. The metastasis in vivo were observed. Proliferation and migration of HCT-8-7T cells and their parental cells were assessed by colony formation and Transwell assay, respectively. Glycolytic capacity and glutamine metabolism of cells were analyzed by metabolism assays. The protein and mRNA levels of critical factors which are involved in mediating glycolysis and epithelial-mesenchymal transition (EMT) were examined by western blot and reverse transcription-quantitative real-time polymerase chain reaction(RT-qPCR), respectively. Results: In comparison with the mice transplanted with HCT-8 cells, which were survival with limited metastatic tumor cells in organs, aggressive metastases were observed in liver, lung, kidney and ovary of HCT-8-7T transplanted mice (P<0.05). The levels of ATP [(0.10±0.01) mmol/L], glycolysis [(81.77±8.21) mpH/min] and the capacity of glycolysis [(55.50±3.48) mpH/min] in HCT-8-7T cells were higher than those of HCT-8 cells [(0.04±0.01) mmol/L, (27.77±2.55) mpH/min and(14.00±1.19) mpH/min, respectively, P<0.05]. Meanwhile, the levels of p53 protein and mRNA in HCT-8-7T cells were potently decreased as compared to that in HCT-8 cells (P<0.05). However, the level of miRNA-125b (2.21±0.12) in HCT-8-7T cells was significantly elevated as compared to that in HCT-8 cells (1.00±0.00, P<0.001). In HCT-8-7T cells, forced-expression of p53 reduced the colon number (162.00±24.00) and the migration [(18.53±5.67)%] as compared with those in cells transfected with control vector [274.70±40.50 and (100.00±29.06)%, P<0.05, respectively]. Similarly, miR-125b mimic decreased the glycolysis [(25.28±9.51) mpH/min] in HCT-8-7T cells as compared with that [(54.38±12.70)mpH/min, P=0.003] in HCT-8-7T cells transfected with control. Meanwhile, in comparison with control transfected HCT-8-7T cells, miR-125b mimic also significantly led to an increase in the levels of p53 and β-catenin, in parallel with a decrease in the levels of PFK1 and HK1 in HCT-8-7T cells (P<0.05). Conclusions: Silencing of p53 by miR-125b could be one of the mechanisms that contributes to Alisertib resistance. Targeting miR-125b could be a strategy to overcome Alisertib resistance.

Abstract
Sleep is a highly conserved phenomenon in endotherms, and has a universal physiological function across all species. In mammals, sleep can be divided into two stages: rapid eye movement (REM) sleep and non-REM (NREM) sleep, which alternate in a cyclic manner. Humans spend about one-third of their lives asleep. Sufficient sleep is necessary for humans to sustain everyday functioning. Sleep plays an important role in regulating energy metabolism, immune defense, endocrine function, and the consolidation of memory process. With the development of social economy and the change of life style, sleep duration of the residents has gradually decreased and the incidence of sleep disturbances has increased. Sleep disturbances can lead to severe mental disorders, such as depression, anxiety disorders, dementia, and other mental diseases, and may increase the risk of physical diseases, such as chronic inflammation, heart disease, diabetes, hypertension, atherosclerosis and others. Maintaining good sleep is of great significance for developing social productive forces, promoting sustainable development of economic society, and is a necessary condition for carrying out the "Healthy China Strategy". The sleep research in China started in 1950s. After decades of development, researchers have made great progress in the molecular mechanisms of sleep and wakefulness, the pathogenesis of sleep disorders and the development of new therapies. With the advancement of science and technology and the public's attention to sleep, the level of clinical diagnosis and therapy of sleep disorders in China is gradually brought in line with international standards. The publication of diagnosis and treatment guidelines in the field of sleep medicine will promote the standardization of the construction. In the future, it is still necessary to promote the development of sleep medicine in the following aspects: Strengthening the professional training and discipline construction, improving the cooperation of sleep research, promoting the intelligent diagnosis and treatment of sleep disorders, and developing the new intervention strategies. Therefore, this review will comprehensively summarize the origin, current situation, and future expectations of sleep medicine in China, including discipline construction of sleep medicine, the number of sleep project grants, research findings, the status and progress of diagnosis and treatment of sleep disorders, and the development direction of sleep medicine.

Abstract
Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Abstract
N6-methyladenosine (m6A) exists widely in eukaryotes as a post-transcriptional modification. This modification is dynamically and reversibly regulated by methyltransferases and demethylases, and is involved in regulating biological effects through m6A binding proteins. Recent studies have elucidated that m6A is involved in embryonic skin morphogenesis, wound repair, and pathophysiological processes such as inflammatory response, angiogenesis, and fibrosis. This review summarizes the role of m6A and its related proteins in the related pathophysiological processes of wound repair, so as to provide a new theoretical basis for the treatment strategy of wound repair.

Abstract
Objective: To explore the changes of γ-GCS mRNA expression and GSH-PX in serum of workers exposed to manganese in order to provide scientific basis for early diagnosis of manganese poisoning. Methods: In June 2017, a total of 180 workers from a motorcycle manufacturer were selected by stratified random sampling, including 115 welders as the exposure group and 65 administrative office workers as the Control Group, the exposure group was divided into high exposure group (43 persons) and low exposure group (72 persons) according to whether the exposure group exceeded the standard limit. The levels of γ-gcs Mrna expression and GSH-Px activity in serum were determined by Occupational Health Survey, and the differences of γ-gcs Mrna expression and GSH-Px activity among different groups were analyzed. Results: Compared with the control group, the serum GSH-Px activity was lower and the serum γ-GCS mRNA expression level was higher in the exposed group (F=370.52, 275.95, P<0.01) . Compared with the control group, there was significant difference in γ-GCS mRNA expression level and GSH-Px activity (F=0.475、1.06, P<0.01; F=48.53、111.70, P<0.01) . The concentrations of manganese in air, welding dust and urine were positively correlated with the level of γ-GCS mRNA (r=0.71, 0.50, 0.31, P<0.01) The serum GSH-Px activity was negatively correlated with the concentrations of manganese in air, welding dust and urine (r=-0.80, -0.52, -0.30, P< 0.01) , There was no correlation between Serum γ-GSH-Px activity and age and years of exposure (P>0.05) . Conclusion: Serum γ-GCS mRNA expression level and GSH-Px activity level can be used as early biomarkers of manganese poisoning. The concentrations of manganese in workplace air, welding dust and urine manganese in workers are the influencing factors.

Abstract
Influenza is an infectious respiratory disease caused by the influenza viruses. Older people, infants and people with underlying medical conditions could have a higher risk of severe influenza symptoms and complications. The co-infection of Coronavirus Diseases 2019 (COVID-19) with influenza viruses could lead to the complication of prevention, diagnosis, control, treatment, and recovery of COVID-19. Influenza vaccine and COVID-19 vaccine overlapped in target populations, vaccination time, and inoculation units. Although there was insufficient evidence on the immunogenicity and safety of co-administration of influenza vaccine and COVID-19 vaccine, World Health Organization and some countries recommended co-administration of inactivated influenza vaccine and COVID-19 vaccine. This review summarized domestic and international vaccination policies and research progress, and put forward corresponding suggestions in order to provide scientific support for the formulation of vaccination strategy on seasonal influenza vaccine and COVID-19 vaccine.

Abstract
Objective: To investigate whether vestibular-evoked myogenic potentials(VEMPs) can be used to assess brainstem involvement in patients with Kennedy's disease (KD). Method: This was a case-control study.Twenty consecutive patients with genetically confirmed KD and 20 age-and sex-matched healthy subjects were enrolled from November 2018 to September 2020.All subjects were tested for three types of VEMPs, including cervical VEMP (c-VEMP) recorded by the sternocleidomastoid muscle (parameter:p13, n23), masseter VEMP (m-VEMP) recorded by the masseter muscle(parameter: p11), and ocular VEMP (o-VEMP) recorded by the inferior oblique muscle (parameter n10, p15).The latency of each wave, interside peak latency and interpeak latency of c-VEMP, the corrected amplitude and amplitude asymmetry ratio were recorded. Bilateral sternocleidomastoid muscle (SCMM) electromyography (EMG) was performed. The spinal cord and bulbous muscular atrophy functional rating scale (SBMAFRS) was used for assessment. Results: The mean p13 latency of c-VEMP was (15.5±1.4)ms, which was longer than that of the control group[(13.3±0.9)ms](P<0.05); the mean n23 latency was(25.5±1.4)ms, which was also longer than that of the control group[(22.5±1.0)ms] (P<0.05); the difference of bilateral p13[(2.3±0.6)ms] was significantly higher than that of the control group(P<0.05). The abnormal rates of c-, m-, o-VEMP in KD patients were 75%(15/20), 30%(6/20) and 20%(4/20), respectively. There was a significant positive correlation between c-VEMP latency and course of disease in KD patients(left: r=0.715, 0.695, right: r= 0.708, 0.715, both P<0.05). However, c-VEMP latency was negatively correlated with SBMAFRS score (left: r=-0.701, -0.694, right: r=-0.644, -0.685, both P<0.05). Abnormal rates of SCMM EMG in KD group were as follows: 15%(3/20)of patients showed spontaneous potential in resting state and 45% (9/20) of patients exhibited simple recruitment. Conclusions: The c-VEMP latency is a sensitive tool for detecting lower brainstem involvement in patients with KD, and the degree of damage increases with prolongation of disease course. The o-and m-VEMP abnormalities indicate that some KD patients develop upper brainstem damage.

Abstract
Objective: To investigate the factors related to myasthenic crisis (MC) in myasthenia gravis patients (MG) with oropharyngeal involvement during hospitalization. Methods: The clinical data of 99 MG patients with oropharyngeal involvement who were admitted to Beijing Tongren Hospital from 2018 to 2020 were retrospectively reviewed. There were 52 males and 47 females, aged 17-89 (55±15) years old, with a disease duration of 1-240 [10 (4, 36)] months. Multivariable logistic regression analysis was used to determine the factors associated with MC. Results: A total of 19 (19.19%) patients developed into MC during hospitalization. Multivariate logistic regression analysis showed that age of hospitalization ≥ 60 years old (OR=31.378, 95%CI: 3.868-254.557, P=0.001), type B and C thymoma (OR=29.175, 95%CI: 2.986-285.016, P=0.004), excess oropharyngeal secretions (OR=12.649, 95%CI: 2.057-77.783, P=0.006) and infections (OR=9.539, 95%CI: 1.345-67.645, P=0.024) were independently related to MC in MG patients with oropharyngeal involvement. Conclusions: Older age, malignant thymoma, excess oropharyngeal secretions and infection are independently related to MC in MG patients with oropharyngeal involvement during hospitalization. Therefore, great attention should be paid to this type of MG patients, and increased oropharyngeal secretions and various infections should be actively treated, so as to reduce the occurrence of MC.

Abstract
Objective: To explore whether the cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) can improve the survival rate of colorectal cancer patients with peritoneal metastasis. Methods: The relevant studies were systematically retrieved from PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP database, and the study of French Elias' team on peritoneal metastasis was retrieved manually. Inclusion criteria: (1) The patients were colorectal cancer peritoneal metastasis. (2) There were CRS+HIPEC treatments (treatment group) and other treatments (control group). (3) Survival analysis data of treatment group and control group were available. (4) Types of studies were randomized controlled trials, cohort studies, or case-control studies. (5) The literature was in Chinese or English. Exclusion criteria: (1) studies without full-text; (2) studies without complete data. The literature screening and data extraction were carried out by two people independently, and the third person decided on the literature with differences. The extracted data included authors, year of publication, number of patients, time of enrollment, time of follow-up, studies design, treatment regimen, hazard ratio (HR) and 95% CI of treatment group and control groups. If the HR and 95% CI of the treatment group and control group were not provided in the literature, Engauge Digitizer 11.1 software was used to extract the time of follow-up and the survival rate at the corresponding time point from the survival curves of both groups, and the HR and 95% CI of both groups were calculated by combining the number of both groups. The quality of study was evaluated by Newcastle-Ottawa scale (NOS) or Cochrane collaboration's tool for assessing risk bias. STATA 15.1 software was used for statistical analysis. HR and 95% CI of both groups were pooled and analyzed. Inter-trial heterogeneity was assessed by Q test and I(2) statistics. When there was no significant heterogeneity (Q test: P≥0.10), fixed-effect model was used for pooled analysis. When significant heterogeneity existed (Q test: P<0.10), random effect model was used for pooled analysis, and subgroup analysis was used to find out the source of heterogeneity. Sensitivity analysis was used to evaluate the stability of the pooled results. Publication bias was assessed by Egger's test and Begg's test (P<0.05 indicated publication bias) and it is reflected by the visual symmetry of Begg's funnel plot on the natural logarithm of HR. Results: A total of 10 studies were enrolled in the meta-analysis, including 1 randomized controlled trial and 9 cohort studies. The risk of bias in 1 randomized controlled trial was uncertain, and 9 cohort studies were all higher than 7 points, indicating high quality literatures. There were 781 patients in treatment group receiving CRS+HIPEC and 2452 patients in control group receiving other treatment, including tumor cytoreductive surgery (CRS), palliative chemotherapy (PC) and intraperitoneal chemotherapy (IPC). The results of pooled analysis by random effect model showed that the OS rate in treatment group was significantly higher than that in control group (HR=0.43, 95% CI: 0.34-0.54), but the heterogeneity of the study was high (P=0.024, I(2)=52.9%). The subgroup analysis of different control treatments showed that the OS rate in treatment group was significantly higher than that in CRS control group (HR=0.63, 95% CI: 0.44-0.90), in PC control group (HR=0.37, 95% CI: 0.32-0.43), in CRS+ IPC control group (HR=0.60, 95% CI: 0.37-0.96), and the heterogeneity of each subgroup was low (CRS control group: P=0.255, I(2)=22.9%; PC control group: P=0.222, I(2)=29.9%; CRS+IPC control group: P=0.947, I(2)=0). Due to the low heterogeneity of subgroups, fixed-effect models were used to pool and analysis. The results of sensitivity analysis revealed that there was little difference between the pooled analysis results after each study was deleted, suggesting that the pooled analysis results were more reliable. Publication bias detection of each study showed Begg's test (P=0.088) >0.05 and Egger's test (P=0.138)>0.05. According to the Begg's funnel plot, the scatter point distribution was basically symmetric, indicating that there was no publication bias in the included study. Conclusion: CRS+HIPEC can improve the OS of patients with colorectal cancer peritoneal metastasis.

Abstract
The smoking cessation rate of 1 314 people at high risk of lung cancer in the area of lung cancer screening and early diagnosis and early treatment in Sichuan Province increased from 22.37% at baseline to 41.78% after screening (χ²=227.97, P<0.001), and the smoking amount of persistent smokers decreased from 20 cigarettes per day to 15 cigarettes per day (t=11.76, P<0.001). Those with positive results in lung cancer screening were more likely to quit smoking or continue to quit smoking. Male, younger age or lower education level would increase the risk of continuous smoking or relapse (P<0.05).

Abstract
Objective: To investigate the feasibility and clinical significance of a continuous auscultation recorder of bowel sounds based on artificial intelligence in monitoring the bowel sounds. Methods: From November 1,2018 to August 12,2019, a continuous auscultation recorder of bowel sounds was applied to monitor the perioperative bowel sounds of 31 patients undergoing colorectal surgery, in order to discovery underlying rules which might be used to guide clinical practice. Results: After the operation, the bowel sounds continued to exist for (1.8±0.8) h, and then gradually weakened or disappeared, and recovered gradually after (11.2±3.5) h. The first exhaust and the first defecation were detected at the time of (22.7±5.8) h and (28.7±6.9) h after surgery, respectively. The bowel sounds rate increased after eating, and decreased significantly after exhaust/defecation. Conclusions: The continuous auscultation recorder of bowel sounds based on artificial intelligence was safe and effective, which can afford help to clinical evaluation.

Abstract
Objectives: To investigated whether berberine could ameliorate septic cardiomyopathy in a rat model of sepsis and it's mechanisms. Methods: SD rats were divided into 3 groups: sepsis group (LPS group), rats were intraperitoneal injected of LPS (10 mg/kg); Berberine intervention group (Ber group), Ber (50 mg/kg, one time per day) was gavage fed 3 days before intraperitoneally injection of lipopolysaccharides (LPS); control group (Con group), rats were gavage fed with double distilled water (2 ml/100 g, one time per day) 3 days before intraperitoneal injection of normal saline (1 ml/100 g). LPS group and the Ber group was further divided into 3 subgroups (n=6), and the follow-up experiments were conducted at 6 h, 24 h and 48 h after LPS injection (of which 48 h subgroup rats were gavage fed with Ber/saline at 24 h). Left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), and the maximum rate of change of left ventricular pressure (±dp/dtmax) were monitored, the level of cardiac troponin T (cTnT), tumor necrosis factor (TNF)-α and interleukin (IL)-1β was detected by ELISA method, HE staining of myocardial tissues was done to observe myocardial injury; Western blotting method was used to detect the expression of toll-like receptor 4(TLR4) protein in rat myocardial tissue, the level of myocardial cell nucleus protein p65 was detected to reflects the degree of NF-κB activation. The correlation of factors was analyzed with Pearson correlation analysis. Results: Pre-treatment with berberine stabilized cardiac hemodynamics and improved the systolic function and diastolic function in the heart of LPS-induced rats, as evidenced by the partial recovery of the reduced±dp/dtmax and LVSP, as well as the decreased LVEDP. Compared with the LPS group, the Ber group showed improved myocardial injury, as demonstrated by decreased cTnT at each time point. HE staining results showed that berberine decreased inflammatory cell infiltration and LPS-induced cell swelling. These effects were observed early at 6 hours, severe at 24 hours, and become more serious at 48 hours after LPS injection. Further, TLR4 and NF-κB p65 subunits, which were the two key factors of the TLR4/NF-κB signaling, were upregulated in the LPS group and attenuated in the Ber group. Consistently, the expression levels of the downstream cytokines TNF-α and IL-1β were lower in the Ber group than those in the LPS group (all P<0.05). Myocardial injury markers were positively correlated with the markers of TLR4/NF-κB signals and the downstream host inflammatory factors (all P<0.05). Conclusions: Berberine can improve myocardial injury and cardiac function in sepsis rats, the mechanism is considered to be related to that it can inhibit the activation of TLR4/NF-κB signaling pathway induced by LPS and further reducing the production of TNF-α and IL-1β.

Abstract
Objective: To find more objective evidence and support for clinical classification of Parkinson's disease by means of tremor analysis in patients with early confirmed Parkinson's disease. Methods: A cross-sectional study was conducted to collect 65 patients with early Parkinson's disease treated in the Third Hospital of Peking University from January 2015 to December 2016. Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn-Yahr scale (H-Y scale), Mini-mental state examination (MMSE), Hamilton depression scale (HAMD) were recorded in all patients. According to the ratio of UPDRS rigidity score to tremor score, the patients were divided into tremor dominant (TD), postural instability/gait difficulty (PIGD) and mixed types. All patients were examined by tremor analysis and the results were analyzed and compared. Results: Among the 65 patients, the mean age of onset was (63±10) years, the course of disease was (14±8) months. Twenty-one patients were classified to TD group, 28 patients were classified to PIGD type, and 16 patients with mixed type. There was no significant difference in frequency and amplitude of tremor between the three groups (P>0.05), but the proportion of alternating contraction and harmonic resonance of active and antagonistic muscles in TD group was significantly higher (P<0.05). Twenty patients (71.4%) in TD group showed typical Parkinson's disease manifestations in tremor analysis. Only four patients (14.3%) in PIGD group showed the typical manifestations. More patients in PIGD group showed no clear main peak of tremor at rest. Some patients showed 6-8 Hz/sec peak frequency in posture position and simultaneous contraction of the active and antagonist muscles. These two manifestations occured simultaneously in mixed type patients, including 10 cases (62.5%) with typical Parkinson's disease manifestations. Conclusion: As an objective electrophysiological method to evaluate tremor type, tremor analysis can be used as an important assistant method for clinical classification of Parkinson's disease. It can provide information of the pathway of pathological loss in different types and give important hints in prognosis and treatment.

Abstract
Objective: To investigate the application value of motor unit number index (MUNIX) for diagnosis and assessment progress in patients with amyotrophic lateral sclerosis (ALS). Method: Sixty healthy controls and 60 ALS patients in the clinic were enrolled from May 2017 to December 2018. The bilateral deltoid, abductor digiti minimi, quadriceps femoris and tibialis anterior muscles of the subjects were detected by MUNIX method, and the negative peak amplitude of compound muscle action potential (CMAP) of ulnar nerve, femoral nerve, peroneal nerve, axillary nerve in bilateral was collected. MUNIX and motor unit size index (MUSIX) of muscles were compared between ALS group and control group. The difference between the MUNIX abnormal rate of muscles and abnormal rate of the corresponding CMAP negative peak amplitude in ALS patients was further compared. Meanwhile, the correlation between the disease course of ALS patients and MUNIX and MUSIX was analyzed. Results: Compared with the control group, the MUNIX values of the deltoid, abductor digiti minimi, quadriceps femoris and tibialis anterior decreased significantly (97±24 vs 183±38, 48±17 vs 191±39, 54±15 vs 159±22, 49±16 vs 147±25, all P<0.05). MUSIX values increased ((175±32) μV vs (47±15) μV, (189±34) μV vs (54±16) μV, (170±30) μV vs (49±13) μV, (190± 36) μV vs (48± 14) μV, all P<0.05)). In ALS patients, the abnormal rate of MUNIX was respectively 81%, 87%, 75% and 89%. The negative peak amplitude abnormal rate of corresponding neuralCMAP was 35%, 40%, 31% and 36%, respectively, with a significant difference (P<0.05). There was a negative correlation between MUNIX value and the course of disease in ALS patients (P<0.05), and a positive correlation between MUSIX value and the course of disease (P<0.05). Conclusion: The MUNIX technique exhibits the features of quantifying the proximal upper and lower limb muscles and assessing the loss of motor units in motor neuron degeneration.

Abstract
Objective: An electrophysiological technique was established to determine Motor Unit Number Index (MUNIX), and to investigate the stability of MUNIX. Methods: Fifty healthy subjects (25 males and 25 females) from the Outpatient Service of Peking University Third Hospital between December 2017 and September 2018 were included and divided into 5 groups according to age. The relevant parameters were detected in bilateral deltoid muscle (axillary nerve), double little finger abductor muscle (ulnar nerve), double quadriceps muscle (femoral nerve), double tibialis anterior muscle (peroneal nerve). The same muscle and the same healthy subjects were tested again three months later. Three-step detection were conducted: first, the surface electrode was attached to the muscle belly of each muscle, and the reference electrode was placed 2-3 cm away from the muscle belly. At the same time, the maximum compound muscle action potential (CMAP) of corresponding nerve was obtained, and the negative peak amplitude was measured. The second step was to collect the interference phase of the surface electromyography (SIP). There were 10 levels in total. And the measurement was repeated for three times, and the whole interference phase range was measured in the end. In the third step, the negative peak amplitude and SIP value of CMAP were substituted into the Excel table, and the MUNIX and motor unit number size (MUSIX) values were automatically calculated by the instrument through mathematical functions. Results: The mean MUNIX values of deltoid, extensor little finger, quadriceps femoris and tibial anterior were 193.2, 189.0, 159.7, 147.2, MUSIX were 46.9, 54.3, 49.6, 48.1 μV, respectively. The detection rates of MUNIX and MUSIX in the four muscles were 100%, respectively. With the increase of age, it could be seen that MUNIX declined, with statistically significant difference (P<0.05), but there was no significant change in MUSIX. There was no statistically significant difference in MUNIX and MUSIX between different gender, lateral sides and baseline and 3-month's reexamination results (P>0.05). Conclusions: MUNIX technology can improve the motor unit count of proximal upper limb and lower limb muscles. Its parameters are monitored using a mathematical model based on the composite muscle action potential and the interference phase of surface electromyography. Result is stable and reliable.

Abstract
Objective: To investigate the relationship between the spontaneous focal lamina cribrosa (LC) defect and the progression of visual field defect (VFD) in primary open-angle glaucoma (POAG). Methods: Case-control study. The patients who were diagnosed as POAG with at least 5 visual field results had been collected from June 2018 to January 2019 at Beijing Tongren Hospital Affiliated to Capital Medical University. Serial imaging by swept source optical coherence tomography B-Scan of the optic discs were acquired at the end of the follow-up and LC defects status were reviewed. Intraocular pressure, mean defects of visual field, central corneal thickness and axis length were recorded in the follow-up duration. Eyes were classified as having either progressive or nonprogressive VFD, and associating factors were evaluated by χ(2) or Fisher's test, mixed-effect model analysis and multivariate Logistical regression analysis. Results: A total of 32 subjects (64 eyes) were enrolled in the study with mean age of (47±14) years, the group consisted of 17 males and 15 females. Fourty-five eyes showed nonprogressive VFD. LC defects were more common in eyes without (28/45) rather than with progressive VFD (5/19) (χ(2)=6.896, P=0.009). Eyes with nonprogressive VFD showed longer axis length[(26.82±1.34) mm vs. (25.79±1.44) mm; t=6.589, P=0.013] and wider LC defects diameter[211 (165-326) μm vs. 114 (106-156) μm; Z=4.797, P=0.042]. Multivariate Logistic regression analysis revealed that the presence of LC defect was significantly associated with nonprogressive VFD (odds ratio=0.217, P=0.012). There were 7 subjects with asymmetry VFD and the incedence of LC defects without progression (7/7) is higher than fellow eye with progression (1/7, P=0.002). There was only one patient with progressive VFD showed one LC defect with an smaller diameter (169 μm) than that in the contralateral eyes with stable VFD (269 μm). Conclusions: LC defects are more common in eyes with nonprogressive VFD. Spontaneous LC defects are associated with nonprogressive glaucomatous defects and could be a protective factor for POAG.

Abstract
Objective: To establish a method for detecting multi-segmental motor nerve conduction of axillary nerve using magnetic stimulation technique, and to preliminarily discuss its clinical application value. Methods: From April 2017 to February 2018, 80 healthy volunteers, 40 male and 40 female, were included and divided into five groups according to age and gender (groupⅠwere <35 years old; groupⅡwere 35-44 years old; group Ⅲ were 45-54 years old; groups Ⅳ were 55-64 years old; groups Ⅴ aged 65-74). Axillary nerve recording electrodes were placed in the deltoid muscle belly, reference electrode was placed in the deltoid muscle check point. Using the magnetic stimulation coil, stimulation was released at spots which were, respectively, 2 fingers from the lateral side of subscapular fossa, 2 fingers from the lateral side of infraclavicular fossae, and Erb's point. The latency, amplitude, detection distance (stimulation to recording electrode) were recorded at each spot, and the height and arm length were also measured. Results: The detection rate of axillary nerve waveform in healthy volunteers was 97.2%. There were no statistically significant differences in latency and amplitude in the different sides, gender (P>0.05).The latency corresponding to different detection distances was compared, and the difference was statistically significant (P<0.05).Height and arm length in different age groups were significantly increased in groupsⅠ, Ⅱ and Ⅲ compared with groups Ⅳ and Ⅴ, with statistical significance (P<0.05). When compared among different age groups, the latency and amplitude of group Ⅳand Ⅴ (more than 55 years old and over) were significantly prolonged and decreased, with statistically significant differences (P<0.05). Conclusions: The method of detecting multi-segmental magnetic stimulation of axillary nerve is stable and the result is reliable, which makes the evaluation of the proximal nerve of upper limbs be possible. However, the biological effects of age on nerve conduction should be carefully considered.

Abstract
Emerging evidences indicate that dysregulated long noncoding RNAs (lncRNAs) are implicated in cancer tumorigenesis and progression and might be used as diagnosis and prognosis biomarker, or potential therapeutic targets. LncRNA H19 has been reported to be upregulated in diverse human cancers; however, its clinical significance in gastric cancer (GC) remains elusive. Expression levels of H19 in 128 pairs of GC and adjacent normal tissues, GC cell lines and GC juices compared to their corresponding controls were detected by real-time quantitative polymerase chain reaction (qPCR) assay. A receiver operating characteristic (ROC) curve and Kaplan-Meier analysis were constructed to evaluate the diagnostic and prognostic values. Univariate and multivariate analysis were performed using the Cox proportional hazard analysis. H19 expression was remarkably increased in GC tissues and cell lines compared with that in the normal control, and its up-regulation was significantly correlated to invasion depth (P < 0.001), advanced TNM stage (P = 0.002) and regional lymph nodes metastasis (P < 0.001) in GC. H19 levels were robust in differentiating GC tissues from controls [area under the curve (AUC) = 0.697; 95% confidence interval (CI) = 0.636-0.752, p<0.01]. Kaplan-Meier analysis demonstrated that increased H19 expression contributed to poor overall survival (P = 0.017) and disease-free survival (P = 0.024) of patients. A multivariate survival analysis also indicated that H19 could be an independent prognostic marker. The levels of H19 in gastric juice from gastric patients were significantly higher than those from normal subjects (P = 0.034). Furthermore, knockdown of H19 expression by siRNA could inhibit cell migration and invasion in GC cells partly via regulating E-cadherin protein expression. H19 might serve as a promising biomarker for early detection and prognosis prediction of GC.

Abstract
Objective: To study the integrity of vestibular brain stem pathway and explore the diagnostic and clinical value of vestibular-evoked myogenic potentials (VEMPs) in central nervous system diseases through the establishment of detection method of VEMPs. Method: Seventy-two normal volunteers (included between April 2016 and July 2017) were divided into 6 groups according to different ages.All subjects were tested with short acoustic stimulation.The superior oblique, masseter and sternocleidomastoid muscles were recorded respectively, and the stable waveform was obtained: (1)the Opposite ocular potential (o- VEMP) N1 and P1; (2)the bilateral masseter potential (m-VEMP) P11; (3)the same side neck potential (c-VEMP) P13 and N23.The three detection methods were used to measure the latency period, the amplitude of the peak value, the ratio of the amplitude before and after the stimulus, and the logarithm value of the ratio. Results: The mean values of latency period of N1, P11 and P13 were 10.9-12.0 ms, 11.3-13.6 ms, 13.2-14.6 ms, among which the occurrence rates of o-vemp, m-vemp and c-vemp were respectively 97.2%, 98.5% and 95.4%.With the increase of age, the latency period of each wave was observed to be prolonged, with significant difference (P<0.05), while no significant difference in the gender and side of each wave (P> 0.05). Conclusions: VEMPs are noninvasive measurement technology, stable and reliable, and can objectively evaluate the integrity of the vestibular brainstem pathway from three segment. This technology has broad application prospects in the central nervous system diseases, especially in neurodegenerative disease.

Abstract
OBJECTIVE To prepare ion exchange doxorubicin-loaded poly (acrylic acid) microspheres (DPMs) and evaluate the properties of these chemoembolic agents. METHODS Poly (acrylic acid) microspheres (PMs) without drug were prepared by inverse suspension polymerization method and then doxorubicin was loaded by ion exchange mechanism to prepare DPMs. Optical microscope was used to investigate the morphology and particle size distribution of PMs and DPMs; fluorescence microscope and confocal microscope were used to observe the distribution of doxorubicin after drug loading. Elasticities of both the microspheres were evaluated by texture analyzer. High performance liquid chromatography (HPLC) method was established to determine the drug loading behavior of PMs and releasing behavior of DPMs. The in vivo embolic property was evaluated by embolizing the hepatic artery of a rabbit with 0.1 mL of DPMs. RESULTS PMs and DPMs were both spherical in shape, smooth in surface and dispersed well. Doxorubicin was mainly in the outer area inside of DPMs and distributed evenly. The average particle size of PMs and DPMs were (283±136) μm and (248±149) μm, respectively. PMs and DPMs both had good compression ability with the Young's modulus of (62.63±1.65) kPa and (93.94±1.10) kPa separately. PMs reached the drug loading balance at 12 h, and the entrapment efficiency was greater than 99%. Drug loading of PMs in doxorubicin solution at the concentration of 5.0 g/L and 12.5 g/L was (19.78±0.27) g/L and (49.45±0.37) g/L, respectively. Doxorubicin released slowly from DPMs in PBS and the accumulative release percentages of DPMs with corresponding drug loading were 6.82%±0.02% and 2.83%±0.10% after 24 h, respectively. Arterial angiograms showed that the hepatic artery of the rabbit was successfully embolized with DPMs. CONCLUSION DPMs with good performance of loading doxorubicin could be a potential embolic agent for transcatheter arterial chemoembolization.

Abstract
Objective:To investigate the expression and significance of CTHRC1 in patients with papillary thyroid cancinoma.Method:We collected 63 specimens of papillary thyroid carcinoma tissue with 36 specimens of the adjacent normal thyroid tissue and 23 specimens of thyroid nodular goiter. The expressions of CTHRC1 protein in these tissues were detected by immunohistochemical staining. The correlations between the expressions of CTHRC1 with clinicopathologic features,E-cadherin and Vimentin expression were analyzed.Result:CTHRC1 protein expression levels in papillary thyroid carcinoma tissue were significantly higher than those in adjacent normal thyroid tissue and benign disease(P<0.01);CTHRC1 expression was significantly correlated with lymph node metastases(P<0.05). Moreover,CTHRC1 expression was correlated with the expression of E-cadherin and Vimentin(P<0.01).Conclusion:CTHRC1 is related with the occurrence and miligant transformation of papillary thyroid cancinoma. We speculated that CTHRC1 might play a role in the epithelial-mesenchymal transition of papillary thyroid cancinoma.

Abstract
Objective: To investigate the effects of overexpression of microRNA-7 (miR-7) on the proliferation and invasion of HepG2 cells and the underlying mechanism in vitro. Methods: The relative expression levels of miR-7 and Raf1 in hepatocellular carcinoma (HCC) tissues and adjacent normal tissues (ANT) were detected by quantitative real time-PCR (qRT-PCR). The relationship between the expression of miR-7 and the characteristics of HCC patients was analyzed. Cells were divided into blank control group, negative control (NC) group and miR-7 mimics transfected group, miR-7 mimics and NC were transfected into HepG2 cells by Lipofectamine™2000. The relative expression of miR-7 was detected by qRT-PCR. The proliferation ability of HepG2 cells was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The invasion of HepG2 cells was detected by Transwell assay. The target genes of miR-7 were predicted by TargetScan and the binding effect of miR-7 on the 3'UTR of Raf1 was verified by dual luciferase reporter assay.The expressions of Raf1 protein in hepatocellular carcinoma tissues, normal tissues and miR-7 mimics transfected HepG2 cells was detected by Western blot. The correlation of the levels of miR-7 and Raf1 mRNA was determined by Pearson correlation analysis. Results: The relative expression level of miR-7 in HCC was 0.49±0.02, significantly lower than in ANT (1.21±0.05, P<0.01). The level of miR-7 was significantly correlated the tumor volume, metastasis and prognosis of HCC patients (P<0.05). The relative expression level of miR-7 in miR-7 mimics transfected HepG2 group was 12.67±0.40, significantly higher than that in blank group (P<0.01). Compared with the blank group, the A value and invasion ability of miR-7 mimics transfected group were significantly down-regulated at 48 hours and 72 hours after transfection (P<0.01). Compared with miR-7 NC group, the luciferase activity of wild-type Raf1 reporter gene in miR-7 mimics transfected group was significantly reduced (P<0.01). The relative expression of Raf1 protein in HCC was 3.15±0.10, significant higher than in ANT (0.53±0.03, P<0.01). The relative expression of Raf1 protein in miR-7 mimics transfected group was 0.24±0.01, significantly lower than in miR-7 NC group (0.98±0.02, P<0.01). Furthermore, an negative correlation was observed between the levels of miR-7 and Raf1 in HCC tissues (P<0.05). Conclusions: The expression of miR-7 in HCC is significantly decreased and inversely correlated with poor survival of HCC patients. Overexpression of miR-7 can inhibit the proliferation and invasion ability of hepatocellular carcinoma cells HepG2 by downregulating Raf1 in vitro.

Abstract
Objective: To explore the efficacy and safety of uterine lower posterior wall breakwater-like suture technique in controlling the intraoperative bleeding of placenta previa. Methods: From June 2016 to June 2017, 47 patients were diagnosed placenta previa in Union Hospital, Tongji Medical College of Huazhong University of Science and Technology. Posterior wall breakwater-like suture technique was used preferentially, as for cases with poor myometrium layer, lower anterior wall stitch suture was used at the same time. Bilateral descending branches of uterine artery ligation and Cook balloon compression of uterine lower segment was conducted when necessary. The clinic data of the 47 cases were analyzed. Results: Thirty cases (63.8, 30/47) were diagnosed placenta inccreta or percreta by ultrasound or MRI preoperatively. Senventeen cases were diagnosed as placenta accreta (36.2%, 17/47) . Thirty-four cases had the previous history of cesarean section. The average cervical canal length of 47 patients was (2.8±0.9) cm. There were 19 cases (40.4%,19/47) with 1 time posterior wall breakwater-like sutured and 16 cases (34.0%,16/47) with 2 or 3 times posterior wall breakwater-like sutured; 12 cases (25.5%,12/47) were treated with anterior wall stitch suture simultaneously.Ten cases (21.3%, 10/47) underwent uterine artery ligation, 17 cases (36.2%, 17/47) underwent COOK balloon compression on the staxis surface of lower segment. None of them had postpartum hemorrhage or performed internal iliac artery embolization. The median blood loss in the operation was 700 ml, the percentiles 25 was 500 ml, and the percentiles 75 was 1 200 ml. The blood loss ≥1 000 ml in 18 (38.3%, 18/47) patients,and the most serious one was 2 500 ml. The median blood transfusion volume (including allogenetic transfusion and autotransfusion) was 450 ml, the percentiles 25 was 228 ml, and the percentiles 75 was 675 ml. The average vaginal bleeding volume was (150±63) ml first day after operation. The mean hospitalization time was (4.7±1.0) days. The mean gestational weeks of pregnancy termination was (36.1±1.5) weeks, and the mean birth weight of newborns was (2 817±492) g. Apgar score:1-minute 7.8±1.1, 5-minute 8.9±0.8. No neonatal death, 16 cases were transferred to neonatal ICU (34.0%, 16/47) mainly for premature delivery and low birth weight. No complication was found in 6 months post-operation. Conclusions: Uterine posterior wall breakwater-like suture technique is a simple, safe and effective way in controlling intraoperative bleeding of placental previa.Lower anterior wall stitch suture could effectively stop bleeding and restore the normal uterine shape. Combined application of various methods could significantly reduce the incidence of postpartum hemorrhage and hysterectomy, and improve maternal and fetal prognosis.

Abstract
Objective: To explore the reference intervals of thyrotropin (TSH) and free thyroxine (FT(4)) in normal pregnant women. Methods: Prospective and longitudinal sequential collection of the cases were performed. A total of 155 singleton pregnant women who had regular prenatal examination and delivery in West China Second Hospital of Sichuan University from January 2015 to December 2015 were included as the research group. Blood samples were sequentially collected from the pregnant women at the first (9-13(+6) weeks) , the second (24-27(+6) weeks) , the third (32-36 weeks) trimesters, respectively. Another 155 non-pregnant women were selected as the control group simultaneously, in an effort to establish a range of reference intervals of thyroid index in each period of pregnancy. Meanwhile, neonatal plantar blood were also collected on special filter paper and TSH levels were measured. Results: (1) TSH reference intervals [percentile 2.5-percentile 97.5 (P(2.5)-P(97.5)) ] were 0.08-3.29 mU/L, 0.59-4.22 mU/L and 0.81-4.33 mU/L in three trimesters respectively. FT(4) reference intervals were 11.88-20.06 pmol/L, 9.89-15.80 pmol/L and 9.22-15.77 pmol/L in three trimesters respectively. (2) The median serum TSH in the first trimester (1.35 mU/L) was lower than that in the second trimester (2.15 mU/L) , the third trimester (2.19 mU/L) , and the control group (2.19 mU/L) . The differences were all statistically significant (P<0.05) . There was no significant difference in median serum TSH between the second trimester and the third trimester, the second trimester and the control group, and the third trimester versus the control group. (3) The median serum FT(4) in the first trimester (15.16 pmol/L) was higher than that in the second trimester (12.39 pmol/L) and the third trimester (12.26 pmol/L) . The differences were both statistically significant (P<0.05) . The median FT(4) in the second trimester and the third trimester was lower than that in the control group (15.64 pmol/L) , and the differences were both statistically significant (P<0.05) . (4) In the first trimester, the median serum total triiodothyronine (TT(3)) level (2.32 nmol/L) was higher than that in the control group (1.56 nmol/L) , total thyroxine (TT(4)) level (154.60 nmol/L) was also higher than that in the control group (98.25 nmol/L) , and free triiodothyronine (FT(3)) level (4.70 pmol/L) was lower than that in the control group (4.84 pmol/L) , the differences were all statistically significant (P<0.05) . (5) The TSH levels of all neonatus were normal [ (2.1±1.3) mU/L]. Conclusions: The thyroid hormone levels between pregnant women and non-pregnant women are significantly different. Moreover, the reference intervals are vary with pregnancy period. It is important to establish the specific reference intervals of thyroid hormones in the first, second and third trimester of pregnancy specific to local region or unit.

Abstract
AIM The aim of this study was to explain the effects of miRNA-145 in the pathogenesis of preeclampsia. METHODS Collecting the placental tissue of 40 severe preeclampsia patients and 20 normal pregnant women, and observation of the pathological findings by HE staining. Measuring the miR-145 by RT-PCR. EVCT were divided into NC group; MC group and miRNA group. The EVCT cells of MC and miRNA groups were simulated by hypoxia in vivo by CoCl2. Measuring the proliferation rate of different groups by MTT testing. The cells apoptosis rates were measured by flow cytometry; evaluating PI3K, Akt, mTOR and P53 gene and protein expression of three groups by RT-PCR and WB. RESULTS Compared to the normal pregnant placental tissue. The miR-145 expression of preeclampsia pregnant placental tissue was significantly decreased (p < 0.05). In the cell experiments, the proliferation rate was significantly increased, and the cell apoptosis rate was significantly reduced in MC group compared to the MC group (p<0.05, respectively). Comparing with MC group, the PI3K, Akt and mTOR gene and protein expression of miRNA group were significantly up-regulated and the P53 expression was significantly down-regulated (p<0.05, respectively). CONCLUSION miR-145 might have effects to predict preeclampsia via PI3K/Akt/mTOR signalling pathways (Fig. 5, Ref. 30).

Methods: The blood distribution of 509 apparent healthy volunteers of Tueti County and Gal County, Tibet, which were randomly selected from September to November in 2016; 137 Tibetan blood donors, from 2016 September to2017 July and 84 Tibetan blood donors from 2015 August to 2017 July was analyzed retrospectively. The blood type was tested by the slide method. By reviewing the Chinese and foreign language database, seven articles on Tibetan blood group distribution were obtained. And the data of the blood distribution of the Ali area population and the Tibet Tibetan population were compared. Results: The ABO phenotype frequencies of 507 apparent healthy people, 137 blood donors and 84 recipients were B>O>A>AB. The composition ratio were 36.1%, 34.5%, 21.5 %, 7.9%; 40.1%, 35.0%, 17.5%, 7.3%; 39.3%, 34.5%, 20.2%, 6.0%.There was no statistically significant difference in blood group distribution between the donors and the recipients (P>0.05). And there was no significant difference in the blood group distribution between Ali and Shigatse, Nagqu, Lhasa, Shannan. However, the differences between Ali and Qamdo, Nyingchi areas were statistically significant. Conclusion: The geographical position of the blood from the west to east, B type shows a downward trend, O type blood composition ratio shows an upward trend.

Abstract
BACKGROUND Garzê and Aba form the second largest Tibetan-inhabited area of China. Blood services have never been reported for this region before. OBJECTIVE To assess the current situation and analyse whether a safe and adequate blood supply has been developed in both Garzê and Aba. METHODS We conducted a longitudinal survey covering the period 2011-2016. The subjects of interest were recruited from non-remunerated voluntary donation, blood testing, clinical transfusion practices and infrastructure of local blood service systems. RESULTS The donation rate and blood collection volume were below the average levels of both the Sichuan Province and mainland China. Component therapy was widely used, but inappropriate usage of whole blood existed. A lack of national specific standards for people on the plateaus led to local blood transfusions being conducted without full clinical assessment. Endemic and frequently occurring disease, such as hydatid disease and gastrointestinal disease, were inevitable risks for blood utilisation and safety. The potential influence of religious belief and traditions, like 'male-leaving marriages', of Tibetans on donor recruitment and blood safety requires further research. CONCLUSIONS A relatively safe and complete blood service system has been developed in this region. However, there is still an urgent need for comprehensive and effective support from the government in terms of policies and finance. As an epidemic area of hydatid disease and sexually transmitted disease, this region needs to emphasise public health measures, such as blood safety and inappropriate usage of blood products.

Abstract
Tumor-associated macrophages (TAMs) play an essential role in metastasis. However, what enables TAMs to have a superior capacity to establish pre-metastatic microenvironment in distant organs is unclear. Here we have begun to uncover the effects of cytochrome P450 (CYP) 4A in TAMs on lung pre-metastatic niche formation and metastasis. CYP4A+ TAM infiltration was positively associated with metastasis, pre-metastatic niche formation and poor prognosis in breast cancer patients. The pharmacological inhibition of CYP4A reduced lung pre-metastatic niche formation (evidenced by a decrease in vascular endothelial growth factor receptor 1 positive (VEGFR1+) myeloid cell recruitment and pro-metastatic protein expression) and metastatic burden, accompanied with TAM polarization away from the M2 phenotype in spontaneous metastasis models of 4T1 breast cancer and B16F10 melanoma. Co-implantation of 4T1 cells with CYP4A10high macrophages promoted lung pre-metastatic niche formation and metastasis. Depletion of TAMs disrupted lung pre-metastatic niches and thereby prevented metastasis. Treatment with the CM from CYP4A10high M2 macrophages (M2) increased pre-metastatic niche formation and metastatic burden in the lungs, whereas CYP4A inhibition attenuated these effects. In vitro TAM polarization away from the M2 phenotype induced by CYP4A inhibition decreased VEGFR1+ myeloid cell migration and fibronectin expression, accompanied with downregulation of STAT3 signaling. Conversely, overexpression of CYP4A or exogenous addition of 20-hydroxyeicosatetraenoic acid promoted M2 polarization and cytokine production of macrophages and thereby enhanced migration of VEGFR1+ myeloid cells, which were reversed by siRNA or pharmacological inhibition of STAT3. Importantly, a combined blocking M2 macrophage-derived factors TGF-β, VEGF and SDF-1 abolished VEGFR1+ myeloid cell migration and fibroblast activation induced by CYP4A. In summary, CYP4A in TAMs is crucial for lung pre-metastatic niche formation and metastasis, and may serve as a potential therapeutic target in human cancer.

Abstract
Objective: To investigate the value of DNA content in comet tail (TailDNA) in predicting the changes in peripheral blood cell counts in workers exposed to benzene. Methods: In 2011, cluster sampling was used to select 150 male workers exposed to benzene in a petrochemical factory. Cubital venous blood and urine samples were collected for routine blood rest, comet assay, and measurement of s-phenylmercapturic acid (SPMA) and urine creatinine. The population was divided into groups according to urinary SPMA or TailDNA, and routine blood test results within 3 years were collected to analyze the changes in blood cell counts. Results: The low-SPMA group had significantly higher white blood cell and neutrophilcounts in all years than the high-SPMA group (P<0.05) . The low-Tail DNA group had a significant increase in platelet count from 2012 to 2014 (P<0.05) , while the high-Tail DNA group had no significant change (P>0.05) . During the 4-year period, the high-TailDNA group had a significantly lower red blood cell count than the low-TailDNA group (P<0.05) . The high-TailDNA group showed a gradual reduction in white blood cell count over time (β=-0.113, P<0.05) , and the low-TailDNA group showed no trend of the reduction in white blood cell count (P>0.05) . Conclusion: TailDNA can be used to predict the changes in blood cell counts in workers exposed to benzene.

Abstract
We compare the results of simulated and measured power efficiency and far-field beam pattern, for two reflective Fourier phase gratings, designed to generate 2 × 2 and 2 × 4 beams respectively from a single-beam, coherent source at 1.4 THz. The designed surface structures were manufactured on aluminum plates by a computer numerical control (CNC) micro-milling machine. Despite small differences between the designed and fabricated gratings, we measured power efficiencies of both gratings to be around 70%, which is in a good agreement with the simulated values. We also find a good agreement between the simulated and measured diffracted beam size and spatial distribution. We demonstrate the application of both gratings as multiple beam local oscillators to simultaneously pump (or operate) a 4-pixel array of superconducting heterodyne mixers.

Abstract
Objective:The purpose of this study was to investigate the expression level of kidney injury molecule l (KIM-1), cystatin C (Cys C) and β2-microglobulin (β2-MG) in patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) disease, and to assess the clinical significance among these factors in OSAHS patients with early renal injury.Method:Total 80 OSAHS patients diagnosed by polysomnogram (PSG) in the sleep disorder lab were selected as experimental group and 15 healthy adults who were normal in PSG examinations were selected as control group. Measure the levels of Cys C, β2-MG in fasting venous blood in the morning and detecte the level of KIM-1 in midpiece urine after centrifugation by enzyme-linked immunolsorbent assay (ELISA). All data were analyzed by the SPSS13.0 statistical software.Result:①According to AHI grouping: the average levels of uric KIM-1 in the moderate and severe patients were higher than healthy control group (P< 0.01). The serum levels of Cys C and β2-MG in severe OSAHS patients were higher than healthy control group (P< 0.01). Besides, the difference of the average levels of uric KIM-1 among the mild, moderate and severe OSAHS patients was statistically significant (P< 0.01) and the serum level of Cys C and β2-MG only in severe OSAHS patients were higher than mild and moderate OSAHS patients (P< 0.01). ②According to LSaO₂ grouping: the average level of KIM-1, Cys C and β2-MG in the severe group were higher than normal control group (P< 0.01). Besides, the average level of KIM-1, Cys C and β2-MG in severe group were higher than mild and moderate groups (P< 0.01). ③KIM-1, Cys C and β2-MG were positive correlated with each other and AHI (P< 0.01). ④KIM-1, Cys C and β2-MG were negative correlated with LSaO₂ (P< 0.01). Conclusion:The urine level of KIM-1 might be a sensitive indicator in OSAHS patients with early renal damage. It was better to evaluate renal injury by AHI grouping than LSaO₂ in OSAHS patients.

Abstract
OBJECTIVE To investigate the risk factors of peripartum hysterectomy in placenta previa through retrospective study of 3 840 placenta previa cases. METHODS The clinical data of 3 840 patients with placenta previa who delivered in West China Second University Hospital between Jan 2005 and June 2014 were analyzed retrospectively. The relationship of certain factors and peripartum hysterectomy was analyzed, including maternal age, residence place, parity, prior curettage, prior cesarean section, twin or multiple pregnancy, antenatal vaginal bleeding, type of placenta previa, suspected placenta accreta, antenatal level of hemoglobin and gestational age at delivery. RESULTS The prevalence of placenta previa was 4.84%(3 840/79 304)in West China Second University Hospital during the study period, and the incidence of preipartum hysterectomy in patients with placenta previa was 2.76%(106/3 840). One-factor analysis demonstrated that residence place, parity, times of prior curettage, prior cesarean section, prenatal vaginal bleeding, anterior placenta, type of placenta previa, placenta accreta, antenatal anemia and gestational age at delivery were potential risk factors for peripartum hysterectomy(P<0.01). Variables with P<0.1 in one-factor analysis were introduced to multi-factor logistic regression analysis, which suggested that one prior cesarean section(OR=12.9,95% CI:6.3-26.3), two or more prior cesarean sections(OR=14.4, 95%CI:3.9-53.2), anterior placenta(OR=4.8, 95%CI:2.1-10.7), complete placenta previa(OR=5.9, 95%CI: 1.8-42.5), placenta accreta(OR=11.2, 95%CI:6.8-18.6), antenatal hemoglobin<100 g/L(OR=1.7, 95%CI: 1.0-2.8)and delivery before 34 gestational weeks(OR=3.2, 95%CI: 1.6-6.3)were independent risk factors of peripartum hysterectomy in patients with placenta previa(P<0.05). CONCLUSIONS Prior cesarean section, anterior placenta, complete placenta previa, placenta accreta, antenatal anemia and delivery before 34 gestational weeks are high risk factors of peripartum hysterectomy in placenta previa patients. Perinatal care and risk evaluation before cesarean section are important to improve perinatal outcomes and reduce peripartum hysterectomy.

Abstract
OBJECTIVE To investigate the incidence and pregnant outcome on vaginal birth after cesarean (VBAC). METHODS From January 2005 to December 2015, clinical data of 507 cases with VBAC in West China Second Hospital were studied retrospectively. There were 370 cases of VBAC from January 2013 to December 2015 as study group (VBAC group), in contrast, 740 cases of elective repeat cesarean section (ERCS group) and 740 primiparas of vaginal delivery without history of cesarean section as control groups, the pregnancy outcome were analyzed between the study group and control groups respectively. RESULTS (1) There were 76 547 total births from January 2005 to December 2015. Among these, 10 178 (13.296%, 10 178/76 547) patients had a single prior low transverse cesarean section, of which 4.981% (507/10 178) had VBAC. The incidence of VBAC was rising from 1.020%-3.704% during 2005-2012 to 6.028%-7.662% during 2013-2015. The rate of scared uterus during 2013-2015 was 18.269% (5 539/30 319), of which 9.26% (513/5 539) chose trial of labor after cesarean section (TOLAC). Successful VBAC occurred in 72.12% (370/513) of patients with TOLAC, and 27.88% (143/513) delivered by emergency cesarean. (2) The following parameters of the successful group and the unsuccessful VBAC group were compared, maternal age (29±4) versus (34±4) years, body mass index at prenatal visit (22.2±1.4) versus (22.6±1.4) kg/m(2), gestational age (38.7±0.9) versus (39.6±1.3) weeks, birth weight (3 326±317) versus (3 404±285) g, and the rate of induction of labor 0 (0/370) and 6.29% (9/143), there were significant differences (all P<0.01). There was no statistical difference between two group for lower uterine segment (P=0.947). (3) The duration of labor of VBAC group and 740 primiparas of vaginal delivery without history of cesarean section was compared, (10.3±1.8) versus (11.5±2.0) hours, there was significant difference (P<0.01). There were no statistical difference between two groups for the following parameters, including postpartum hemorrhage, hospitalization duration, the ratio of 5-minute Apgar score≥8, neonatal admission rate (all P>0.05). (4) The postpartum hemorrhage and hospitalization duration in VBAC group incidence were respectively (194±34) ml and (2.32±0.49) days, and the indexes of the ERCS group were respectively (419±57) ml and (4.14±0.78) days, there were significant differences (all P<0.01). There were no statistical difference between two groups for the ratio of 5-minute Apgar score≥8 and neonatal admission rate (all P>0.05). CONCLUSIONS The majority of patients choose ERCS rather than TOLAC. It's important to assess the indications and contraindications of patients for the successful VBAC, and to monitor maternal and fetal conditions during the delivery process. The premise of TOLAC is a comprehensive understanding of closely monitoring the progress of delivery. Compared with the ERCS, VBAC could reduce patients' postpartum hemorrhage and hospitalization duration, improve the outcomes of pregnancy, and the cesarean section rate could be reduced.

Abstract
Shuangren-Anshen capsule (SAC) is a traditional Chinese herb that was improved in our laboratory. An orthogonal experiment [L9(3)(4)] was used to optimize the extraction conditions. In vivo, a hemorrhage mouse model was established and the hemoglobin contents of normal control, model control, and treated mice were measured. Additionally, the sedative and hypnotic effects of SACs were assessed based on pharmacological parameters such as changes in locomotive activity, forelimb raising, sleep latency, sleep duration, and number of mice that fell asleep. Brain tissue was sectioned and stained to detect changes in cell morphology by microscopy. The optimum extraction was achieved with 3 cycles of decoction for 120 min each with a 10-fold volume of water added. In the model control group, hemoglobin content significantly decreased and pharmacological parameters increased (P < 0.01) relative to that in the normal control group. Compared to the model control group, the group treated with 0.9 g/kg SAC showed significant (P < 0.05) increase or decrease in hemoglobin content and all pharmacological parameters except sleep duration. The groups treated with 1.8 or 3.6 g/kg SAC and the positive control group also showed significant alterations in hemoglobin content and pharmacological parameters (P < 0.05). In addition, SAC exhibited a protective effect on the morphological structures of the damaged nerve cells in the mouse model. Thus, an optimal extraction process was successfully identified. The pharmacological data also suggests that the drug can improve sleep quality. SAC treatment was shown to cause changes in hemoglobin content and cell morphology in a mouse model.

Abstract
OBJECTIVE To investigate the possible reversal effects of 1,3-diphenyl-1,3-propanedione (DPPD) for cocaine-induced content changes of neurotransmitters of brain in mice. METHODS In this study, 36 healthy ICR male mice were randomly divided into control group, cocaine group, three DPPD pretreatment groups (200, 400, and 800 mg/kg) and DPPD alone group (800 mg/kg). The mice in control group were administered intragastrically with 1% Tween 80 for 3 d, and the mice in cocaine group were administered intragastrically with 1% Tween 80 for 2 d before cocaine was injected subcutaneously on the 3rd day. The mice in the three DPPD pretreatment groups were administered intragastrically (DPPD 200, 400, and 800 mg/kg) for 3 d before cocaine was injected subcutaneously 30 min after the administration on the 3rd day. The mice in DPPD alone group were administered intragastrically with DPPD at dose of 800 mg/kg for 3 d. The mice were sacrificed 20 minutes after cocaine injection. The contents of dopamine (DA) and 5-hydroxytryptamin (5-HT) in the mice brain were determined by high performance liquid chromatography (HPLC)-fluorescence detector, the contents of glutamic acid (Glu) and γ-aminobutyric acid (GABA) in the mice brain were determined by HPLC-ultraviolet detector, and the neurotransmitter levels were compared between the groups. RESULTS The results showed that as compared with the control group, DA and GABA contents in cocaine group increased significantly (P<0.01 and P<0.05), while Glu content decreased (P<0.05). As compared with cocaine group, the DA levels in the three DPPD pretreatment groups (200, 400, and 800 mg/kg) all decreased significantly (P<0.01). In DPPD 200 mg/kg pre-administration group, GABA content decreased (P<0.05), and the contents of the four kinds of neurotransmitters had no statistical differences with those of the control group. CONCLUSION DPPD may have potential reversal effects of the content changes of neurotransmitters in mice brain induced by cocaine at a lower dose.

Abstract
OBJECTIVE To investigate the presence of upper motor neuron dysfunction in patients with Charcot-Marie-Tooth disease (CMT) by triple stimulation technique (TST) to provide evidence for gene diagnosis. METHODS A total of 65 CMT patients confirmed by genetic testing from Peking University Third Hospital between August 2013 and August 2015, underwent physical examination and routine electrophysiological tests and triple stimulation technique. The TST combined transcranial magnetic stimulation (TMS) of the motor cortex with peripheral collision studies. The results were expressed by the TST amplitude ratio (TST test/ TST control). Based on the result of physical examination and the ratio of TST, the function of upper motor neuron was assessed. RESULTS All of the CMT patients had typical presentations and were confirmed genetically. Hyperreflexia, Babinski sign and muscular hypertonia were discovered in lower limbs in 7 CMT patients, while 2 patients complicated with hyperreflexia and Hoffmann sign in upper limbs. TST amplitude ratio was significantly altered in 10 patients, including 5 patients with pyramid sign: hyperreflexia, Babinski sign and muscular hypertonia was discovered in lower limbs while 2 patients complicated with hyperreflexia and Hoffmann sign in upper limbs. The disease-causing mutations were: MFN2 mutations in 5 patients, 1 patient with BSCL2 mutation, 3 patients with GJB1 mutations and 1 patient with GDAP mutation. In summary, 18.5% (12 patients) of the 65 CMT patients had upper motor neuron dysfunction based on the result of physical examination and the ratio of TST. CONCLUSION Upper motor neuron dysfunction may be found in CMT patients, which may provide clues for the testing of disease-causing mutations.
