Abstract
Objective: To understand the attitudes toward sexual health education and its correlates among community-based older adults in Shanghai, China. Methods: From June 2020 to December 2022, a cross-sectional survey was conducted among community residents aged ≥50 in Shanghai through multi-stage sampling. The estimated sample size was 735. The questionnaire included sociodemographic characteristics, health characteristics, and history of sexual health education. The multivariable logistic regression model was used to assess the correlates of attitudes toward sexual health education among community-based older adults. Results: A total of 824 participants (489 males and 335 females) with age of (65.1±8.1) years were included, whose main age distribution was 60-69 years (45.3%). The prevalence of supporting sexual health education among older adults was 49.4% (45.2% of men and 55.5% of women). Males (aOR=0.61, 95%CI: 0.44-0.83), aged 70 years and older (aOR=0.62, 95%CI: 0.40-0.94), urban residents (aOR= 2.54, 95%CI: 1.81-3.58), self-reported very good or excellent health status (aOR=1.64,95%CI: 1.04-2.58), having depressive symptoms (aOR=0.37,95%CI: 0.15-0.85), and having a history of sexual health education (aOR=8.64,95%CI: 4.62-17.70) were associated with their attitude toward sexual health education. Conclusions: The proportion of community-based older adults in Shanghai who support sexual health education was not high. Their attitudes toward sexual health education were associated with their self-reported health status, depressive symptoms, and history of sex education. Health professionals and institutions should focus on community-based older adults with key characteristics and tailor interventions to promote the willingness to receive sexual health education among older adults in China and to promote the popularity of sexual health education in this population.

Abstract
Objective: To understand the sexually active status among community-based older adults aged ≥50 years in Tianjin, China, and to explore the potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 was conducted between June 2020 and December 2022. The estimated sample size was 735. The survey collected questionnaire information through face-to-face interviews with investigators, including sociodemographic, health, and sexual lifestyle characteristics. The multivariable logistic regression model was used to assess correlates of sexually active status. Results: A total of 776 study participants (510 males and 266 females) were included, whose major age distribution was 50-59 years (45.9%). The overall sexual activity prevalence of the participants was 45.6%. Older age (60-69: aOR=0.67, 95%CI: 0.45-0.99; ≥70: aOR=0.12, 95%CI: 0.07-0.21), being male (aOR=1.93, 95%CI: 1.32-2.82), living in urban area (aOR=0.18, 95%CI: 0.12-0.28), living with spouse/married (aOR=2.80, 95%CI: 1.41-5.58), living alone (aOR=0.51, 95%CI: 0.27-0.96), having difficulty climbing stairs or walking (aOR=0.55, 95%CI: 0.31-0.97), having chronic diseases (one chronic disease: aOR=0.55, 95%CI: 0.36-0.85; two or more chronic diseases: aOR=0.53, 95%CI: 0.33-0.84) were associated with sexually active status among older adults. Conclusions: Many community-based older adults remained sexually active. There was an association between physical health and sexually active status among community-based older adults. Incorporating sexual health services into healthcare services for community-based older adults could be advocated, with a concurrent emphasis on enhancing the awareness and competence of providing sexual health services among community-based healthcare workers.

Abstract
Objective: To investigate the utilization of sexual health services among community-based older adults in Chongqing and explore its potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 years was conducted in Chongqing between June 2020 and December 2022. A questionnaire including information on demographic characteristics, general health, sexual health status, and sexual health services utilization was collected. Sexual health and reproductive services utilization was defined as having ever been tested for human immunodeficiency virus (HIV), or having had a male/gynecological reproductive health examination in the past year. Logistic regression was used to examine the correlates of the utilization of sexual health services. Results: A total of 794 community-based older adults participated in the study (482 were male, and 312 were female). The mean age was (62.8±8.2) years. The proportion of HIV testing was 18.0%, and the proportion of reproductive health examination was 10.1% among community-based older adults. The results of multivariate logistic regression analysis showed that the age group of 60-69 years (aOR=0.37, 95%CI: 0.18-0.76), female (aOR=11.34, 95%CI: 5.71-22.52), monthly income ≥5 000 yuan (aOR=3.05, 95%CI: 1.01-9.27), being sexual activity (aOR=4.99, 95%CI: 2.23-11.15) was significantly associated with had a reproductive health examination in the past year. Conclusions: The proportion of sexual health services utilization among older adults was low. Older sexual health education should be further strengthened, the close relationship between older adults should be correctly guided and dealt with, and the sexual health services suitable for the older population should be formulated.

Abstract
Objective: To understand the current status of condom use and its correlates among community-based older adults in Chongqing, China. Methods: Cross-sectional study based on a multistage sampling method was conducted in Chongqing from June 2020 to December 2022. The estimated sample size was 735. Through face-to-face interviews, the investigators collected the sociodemographic characteristics, sexual behavior characteristics, awareness of AIDS prevention knowledge, etc. A multivariable logistic regression model was used to explore the correlates of condom use during the last sexual behavior among the participants. Results: A total of 761 participants were included in this study, with 476 males and 285 females, whose average age was (63.8±8.2) years old, mainly in the age group of 60-69 years (44.5%). Among the participants, the rate of condom use during the last sexual behavior was 9.7%. The multivariable logistic regression analysis indicated that correlates of condom use during the last sexual behavior included urban household registration (aOR=2.34, 95%CI: 1.12-4.89), monthly income of 1 000-4 999 Yuan, and 5 000 Yuan and above (aOR=4.49, 95%CI: 1.31-15.41; aOR=16.33, 95%CI: 4.30-62.00), self-assessed sexual behavior risk as very risky/relatively risky (aOR=3.97, 95%CI: 1.40-11.31), awareness of AIDS prevention knowledge (aOR=0.36, 95%CI: 0.21-0.62). Conclusions: The rate of condom use among community-based older adults in Chongqing is low. Comprehensive intervention measures should be taken in combination with the characteristics and needs of community-based older adults to improve awareness of AIDS prevention knowledge and perception of AIDS risk and promote condom use among this population.

Abstract
Objective: To investigate the surgical methods and clinical effects of free superficial peroneal artery perforator flap in repairing small and medium-sized thermal crush injury wounds in the hand. Methods: A retrospective observational study was conducted. From August 2018 to December 2021, 12 patients (19 wounds) with small and medium-sized thermal crush injury in the hand who met the inclusion criteria were hospitalized in Suzhou Ruihua Orthopaedic Hospital, including 5 males and 7 females, aged from 30 to 54 years. The area of the wound was from 2.5 cm×2.0 cm to 14.0 cm×3.5 cm, and all the wounds were repaired by using free superficial peroneal artery perforator flaps from lower leg on one side (including single flap, multiple flaps, and multiple flaps with one pedicle resected from the same donor site). The area of the flap was from 3.5 cm×3.0 cm to 16.0 cm×4.0 cm. The wound in the donor site was sutured directly. The vascular crisis and survival of the flap were observed after operation. The texture, appearance, color, hyperpigmentation, sensation, and two-point discrimination of the flap repaired area were followed up, as well as the hyperplasia of scar and pain condition in the donor and recipient sites. At the last follow-up, the curative effect of flap repair was evaluated by the comprehensive evaluation scale, and the extension and flexion functions of the reserved digital joint were evaluated by the total active movement systematic evaluation method recommended by American Academy for Surgery of Hand. Results: One flap developed arterial crisis on the first day after operation but survived after timely exploration. The other 18 flaps survived successfully after operation. Follow-up of 4 to 24 months after operation showed good texture and appearance in the flap repaired area; the color of the flap repaired area was similar to that of the normal skin around the recipient site, without pigmentation; the protective sensation was restored in all cases, but there was no two-point discrimination; there was no obvious hypertrophic scarring or pain in the donor or recipient site. At the last follow-up, the curative effect of flap repair was evaluated with 3 flaps being excellent and 16 flaps being good; the extension and flexion functions of the reserved digital joint were also assessed, being excellent in 8 fingers, good in 9 fingers, and fair in 2 fingers. Conclusions: The blood supply of superficial peroneal artery perforator flap is sufficient and reliable, and multiple flaps of this type or multiple flaps with one pedicle can be resected from one donor site. The use of this flap to repair small and medium-sized thermal crush injury wounds in the hand results in minimal damage to the donor area, and good postoperative appearance and texture of the flap.

Abstract
Solar flares are one of the severest solar activities that have important effects on near-Earth space. Previous studies have shown that flight arrival delays increase as a result of solar flares, but the intrinsic mechanism behind this relationship is still unknown. In this study, we conducted a comprehensive analysis of flight departure delays during 57 solar X-ray events by using a huge amount of flight data (~ 5 × 106 records) gathered over a 5-year period. It is found that the average flight departure delay time during solar X-ray events increased by 20.68% (7.67 min) compared to quiet periods. Our analysis also revealed apparent time and latitude dependencies, with flight delays being more serious on the dayside than on the nightside and longer (shorter) delays tending to occur in lower (higher) latitude airports during solar X-ray events. Furthermore, our results suggest that the intensity of solar flares (soft X-ray flux) and the Solar Zenith Angle directly modulate flight departure delay time and delay rate. These results indicate that communication interferences caused by solar flares directly affect flight departure delays. This work expands our conventional understanding of the impacts of solar flares on human society and provides new insights for preventing or coping with flight delays.

Abstract
Cyclin-dependent kinases 4/6 (CDK4/6) inhibitors are anti-tumor agents for the treatment of hormone receptor-positive breast cancer. Palbociclib, abemaciclib and dalpiciclib have been approved for the treatment of breast cancer in China. Common adverse effects of CDK4/6 inhibitors include bone marrow suppression, gastrointestinal toxicities, liver dysfunction, and skin or subcutaneous tissue adverse reactions (AEs). The Breast Cancer Expert Group of Chinese Society of Clinical Oncology (CSCO) summarized the incidence, clinical manifestations, and grading of the AEs. This expert consensus reports measures of AE management on the basis of experience of clinical practice and the latest advances worldwide, aiming to guide clinical practice by the way of managing AE and help to choose the best treatment regimen.

Abstract
Objective: To assess the clinical impact of direct two-step distraction reduction (TSDR) for basilar invagination (BI) with atlantoaxial dislocation (AAD). Methods: Retrospective analysis was conducted on the clinical data of patients who underwent TSDR and occipitocervical fusion in West China Hospital between October 2013 and March 2021. Depending on whether the preoperative decrease was greater than 50% on preoperative hyperextension X-rays, the patients were split into two groups. The neurological function [Japanese Orthopedic Association (JOA) score], atlantodens interval (ADI), the distance of odontoid process beyond McRae Line (ML) and Wackenheim Line (WL), cervicomedullary angle (CMA), O-C2 angle (OC2A), and complications incidence were compared between two groups preoperatively and postoperatively. Results: There were 12 men and 23 women among the 35 patients with BI and AAD, and the age ranged from 28 to 71 years, with an mean age of (52.0±13.4) years. In the preoperative reduction ≥50% group, there were 4 males and 9 females with an average age of (54.0±13.8) years; in the preoperative reduction <50% group, there were 8 males and 14 females with a mean age of (50.9±13.4) years. All the patients were followed-up for a mean time of (23.3±13.4) months. There was no significant difference in age, gender, bleeding, length of hospital stay and follow-up time between the two groups (all P>0.05). The JOA score, ADI, WL, ML and CMA of 35 patients were significantly improved when compared with those before operation (all P<0.05). The reduction degree of ADI, ML and WL was more than 80% in 31 cases (88.57%), 30 cases (85.71%) and 31 cases (88.57%), respectively. There was no significant difference in postoperative ADI, ML and WL between the two groups (all P>0.05). All patients had no incision infection, no loosening or breakage of the internal fixators. Dysphagia occurred in 3 patients, non-fusion happened in 1 patient, but no instability in X-ray of cervical dynamic position was found, no loosening or displacement occurred in internal fixators, and partial spontaneous fusion occurred between atlantoaxial lateral mass joints. Conclusions: For BI with AAD without atlantoaxial bony connection or serious atlantoaxial facet joint inclination, TSDR could obtain satisfactory reduction degree. The reduction degree on preoperative hyperextension X-ray doesn't affect the degree of intraoperative reduction.

Abstract
Objective: To explore the clinical effects of proximal ulnar artery perforator flap combined with iliac bone graft in the reconstruction of subtotal thumb or finger defects. Methods: A retrospective observational study was conducted. From August 2016 to August 2019, 7 patients with thumb or finger defects caused by mechanical damage who met the inclusion criteria were admitted to Ruihua Affiliated Hospital of Soochow University, including 6 males and 1 female, aged 46 to 58 years. Their length of fingers was repaired with iliac bone, with length of 2.0 to 3.0 cm. After the bone graft, the skin defect area of the affected finger ranged from 2.8 cm×2.2 cm to 6.0 cm×3.2 cm. Then the free proximal ulnar artery perforator flap with area of 3.0 cm×2.4 cm to 6.5 cm×3.5 cm was used to cover the wounds. The wounds in donor sites of iliac crest and flap were directly sutured. The survival of flap in one week post surgery and the donor site wound healing in 2 weeks post surgery were observed, respectively. During the follow-up, the appearance and sensory function of the affected finger, bone healing, and scar hypertrophy of wound in the donor site were observed and evaluated. At the last follow-up, the functional recovery of the affected finger was evaluated with trial standard for the evaluation of functions of the upper limbs of the Hand Surgery Society of Chinese Medical Association. Results: In one week post surgery, all the flaps survived. In 2 weeks post surgery, the iliac bone and the wounds in forearm donor site healed. During the follow-up of 5 to 13 months, the flap was good in appearance, without obvious pigmentation; the sensory recovery reached level S2 in 5 patients and S0 in 2 patients; all the grafted iliac bones were bony union without obvious resorption; the wounds in donor site healed well, with only mild scar formation. At the last follow-up, the shape of the reconstructed finger was close to the healthy finger, and the functional evaluation results were excellent in 3 cases and good in 4 cases. Conclusions: The use of proximal ulnar artery perforator flap combined with iliac bone graft to reconstruct subtotal thumb or finger can partially restore part of the appearance and function, with less damage to the donor site. It is a good choice for patients who have low expectations of appearance and function for the reconstructed finger.

Abstract
Objective: To screen the differential methylation sites, genes and pathways of air pollution fine particles (PM(2.5)) on human bronchial epithelial (HBE) cells by methylation chip and bioinformation technology, so as to provide scientific basis for further study of the toxicological mechanism of PM(2.5) on HBE cells. Methods: In August 2020, HBE cells were infected with 10 μg/ml and 50 μg/ml PM(2.5) aqueous solution for 24 h, namely PM(2.5) 10 μg/ml exposure group (low dose group) and PM(2.5) 50 μg/ml exposure group (high dose group) ; uninfected HBE cells were used as control group. The DNA fragments were hybridized with the chip, the chip scanned and read the data, analyzed the data, screened the differential methylation sites, carried out GO analysis and KEGG analysis of the differential methylation sites, and analyzed the interaction relationship of the overall differential methylation sites by functional epigenetic modules (FEMs). Results: Compared with the control group, 127 differential methylation sites were screened in the low-dose group, including 89 genes, including 55 sites with increased methylation level and 72 sites with decreased methylation level. The differential methylation sites were mainly concentrated in the Body region and UTR region. Compared with the control group, 238 differential methylation sites were screened in the high-dose group, including 168 genes, of which 127 sites had increased methylation level and 111 sites had decreased methylation level. The differential heterotopic sites were mainly concentrated in the Body region and UTR region. Through FEMs analysis, 8 genes with the most interaction were screened, of which 6 genes had significant changes in methylation level. MALT1 gene related to apoptosis was found in the heterotopic site of methylation difference in low-dose group; PIK3CA and ARID1A genes related to carcinogenesis were found in the heterotopic sites of methylation difference in high-dose group; TNF genes related to tumor inhibition were found in the results of FEMs analysis. Conclusion: After PM(2.5) exposure to HBE cells, the DNA methylation level is significantly changed, and genes related to apoptosis and carcinogenesis are screened out, suggesting that the carcinogenic mutagenic effect of PM(2.5) may be related to DNA methylation.

Abstract
On November 17, 2013, the Second Affiliated Hospital of Kunming Medical University admitted a 23-year-old male patient with a high-temperature steel bar penetration injury from scrotum to buttocks who was transferred from another hospital. Expanded debridement, suture, and drainage of the perineum, right thigh, and right hip were performed as soon as possible after admission. A sputum suction tube was used as the guide mark for expanded debridement during the operation to ensure the accuracy of the direction and scope of expanded debridement. The incision was treated with vacuum sealing drainage (VSD) and full drainage. On the 20th day after the operation (the 25th day after admission), the unhealed wound was transplanted with split-thickness skin graft from the right thigh, and the drainage of the operation area and dressing change were strengthened. On the 53rd day after injury, the patient was discharged after complete wound healing. This case suggests that VSD after early debridement is an effective means to treat high-temperature steel bar penetration injuries.

Abstract
Objective: To explore the current status of alcoholic hepatitis diagnosis by clinicians' in China. Methods: Clinical data of inpatients confirmed with alcohol-associated liver disease diagnosed at Tongliao Infectious Disease Hospital of Inner Mongolia from June 1, 2018 to May 31, 2019 were retrospectively analyzed. The consistency of clinical diagnosis of alcoholic hepatitis was judged according to the diagnostic criteria recommended by the National Institute of Alcohol Abuse and Alcoholism (USA), and then the alcoholic hepatitis severity assessment model recommended by international guidelines, including Maddrey discriminant function, Model for end-stage liver disease, and Glasgow alcoholic hepatitis score and ABIC scores (age, total bilirubin, international normalized ratio and creatinine) were applied to evaluate this group of cases. Results: Among 79 cases with alcohol-associated liver disease, 75 were males and 4 were females, age ranged between 27~75 (51.1±8.8) years. Alcohol consumption varied from 60 g/d to 600g/d, with an average consumption of 148.8 ± 76.6 g/d. The alcohol consumption duration ranged from 4 to 50 [average (23.9 ± 9.6)] years. According to the initial discharge diagnosis, there were 47 and 32 cases in alcoholic hepatitis and alcoholic liver cirrhosis group, respectively. The mean erythrocyte volume, serum alanine aminotransferase, aspartate aminotransferase and total bilirubin were increased in alcoholic liver cirrhosis than alcoholic hepatitis group, while albumin and total cholesterol were lowered in alcoholic liver cirrhosis than alcoholic hepatitis group, and coagulation indexes were significantly extended. Alpha-fetoprotein of both groups were in the normal range; however, it was significantly higher in the alcoholic hepatitis group than the alcoholic cirrhosis group. The 10 cases in the alcoholic cirrhosis group met the definition and diagnosis of alcoholic hepatitis defined by the National Institute of Alcohol Abuse and Alcoholism (USA), but there was no case in the alcoholic hepatitis group. Among the 10 diagnosed cases of alcoholic hepatitis, 5, 6, 1 and 3 cases met the diagnostic criteria of Maddrey discriminant function, Model for end-stage liver disease, Glasgow alcoholic hepatitis score, and ABIC score for severe alcoholic hepatitis, respectively. The Maddrey discriminant function, ABIC score, and Glasgow alcoholic hepatitis score within the Model for end-stage liver disease scores> 20 points had 5, 1, and 3 cases, respectively. Conclusion: Alcoholic hepatitis is over-diagnosed by clinicians. Alcoholic hepatitis patients have the base of liver cirrhosis who meet the diagnostic criteria of National Institute of Alcohol Abuse and Alcoholism (USA). Patients with Model for end-stage liver disease score > 20 points have good consistency with Maddrey discriminant function score ≥ 32 points, and both can be used to evaluate the alcoholic hepatitis patient clinical severity.

Abstract
Objective: To explore the relationship between triglyceride-glucose index (TyG) and non-alcoholic fatty liver disease (NAFLD). Methods: 25 535 cases who participated in the health check-ups at the First Hospital of China Medical University from January 2019 to December 2019 were selected as the eligible subjects. Logistic regression analysis and receiver operating characteristic curve were used to analyze the relationship between TyG index and NAFLD risk and its diagnostic value for NAFLD. Results: NAFLD prevalence was gradually increased with the increase of the TyG index. After adjusting for other potential influencing factors, compared with the first quarter of TyG in patient with NAFLD, the OR (95%CI) in the second, third, and fourth quarter were 1.677 (1.495 ~ 1.881), 2.707 (2.397 ~ 3.057) and 4.049 (3.482 ~ 4.710), respectively. Receiver operating characteristic curve analysis showed that the best cut-off value of TyG index for the diagnosis of NAFLD was 6.9, and the area under the curve was 0.816. The sensitivity and specificity were 77.66% and 70.51%, respectively. The combined application of TyG and ALT levels had higher diagnostic value. Conclusion: TyG, as a simple and convenient biosynthetic index, is closely related to the NAFLD. In addition, when the TyG index is ≥6.9, it has a high diagnostic value for NAFLD.

Abstract
Objective: To investigate the effects of preoperative segmental range of motion (ROM) on clinical and radiographical outcomes after artificial cervical disc replacement (ACDR) and explore whether ACDR could be indicated for patients with preoperative limited or excessive segmental ROM. Methods: From January 2008 to December 2017, patients who underwent Prestige-LP ACDR in West China Hospital were retrospectively reviewed. The preoperative and postoperative X-rays of the cervical spine were collected to measure the radiographic parameters, including cervical lordosis (CL), C(2-7) ROM, disc height (DH), disc angle (DA) and ROM at the arthroplasty level. Clinical outcomes were evaluated using the Japanese Orthopedic Association (JOA) and the Neck Disability Index (NDI) scores. The correlation between preoperative segmental ROM and postoperative clinical and radiographical outcomes were also analyzed. Results: A total of 161 patients were analyzed, with 73 males and 88 females. The mean age was (44±8) years, and the follow-up period was 34 months (12-120 months). JOA and NDI scores improved after ACDR (P<0.05). However, postoperative C(2-7) ROM and ROM at the arthroplasty level were comparable with preoperative counterparts (both P>0.05). Preoperative segmental ROM positively correlated with C(2-7) ROM and ROM at the arthroplasty segment (r=0.213、0.271, both P<0.05), but was negatively correlated with the change of ROM (r=-0.534, P<0.05). The segmental ROM was 4.0°±1.0° in the limited-ROM group (A) and 14.6°±1.3° in the excessive-ROM group (B), respectively. There were significantly more patients diagnosed with cervical spondylosis in group A than in group B (35.5% vs 10.7%, P<0.05). The level-distribution was statistically different between the two groups. C(5/6) and C(6/7) were prone to limited motion in group A, while C(4/5) and C(5/6) were predisposed to excessive motion in group B (all P<0.05). After surgery, C(2-7) ROM increased for 14.2°±16.8° in group A, while paradoxically decreased for 2.2°±14.4° in group B. However, C(2-7) ROM in group B was still larger than that in group A (P<0.05). Similarly, the ROM at the arthroplasty level increased by 3.1°±3.7° in group A, whereas the values decreased by 4.4°±4.2° in group B postoperatively. In addition, group A still had less segmental ROM than group B (P<0.05). The preoperative DH in group A was less than that in group B (P<0.05). The rates of ASD, HO, and high-grade HO in group A were all higher than those in group B but without significant differences (all P>0.05). Conclusion: Preoperative segmental ROM has no significant effects on clinical outcomes after ACDR; it has a positive correlation with postoperative global and segmental ROM while is negatively correlated with ROM change.

Abstract
Objective: To study the effect of p38 mitogen-activated protein kinase (MAPK) gene silencing on expression of apoptotic genes and oncogenes in hepatocytes treated with PM(2.5). Methods: From June to September 2019, according to the p38MAPK gene mRNA sequence provided by GenBank, three interfering sequences were designed and synthesized, ligated into PLVX-shRNA2-puro after annealing, and the recombinant lentiviral vector was transfected into L02 hepatocytes. The p38MAPK silencing cells were identified by real-time fluorescent quantitative PCR and western blotting. The normal L02 cells and p38MAPK silencing cells were treated with 50 μg/mL PM(2.5) water soluble solution, 10 μmol/L positive control Cr(6+), and a blank control group was set up, the treatment time was 24 h. The mRNA levels of oncogenes (c-fos, c-myc, k-ras) , tumor suppressor gene (p53) and apoptotic genes (Caspase-3, Caspase-8, Caspase-9) were detected by real-time PCR. The protein levels of oncogenes and apoptotic genes were detected by Western blotting. Results: The expression levels of p38MAPK mRNA and protein in p38MAPK gene silencing cells were significantly lower than those in L02 hepatocytes (P<0.05) , and the p38MAPK gene silencing cell line was successfully constructed. Compared with the blank control group, the expression levels of the oncogenes c-fos, c-myc, k-ras and the apoptosis genes Caspase-3, Caspase-8 and Caspase-9 increased, the expression level of tumor suppressor gene p53 decreased in the L02 hepatocyte group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Compared with the L02 hepatocytes group treated with PM(2.5) water soluble matter, the expression levels of the oncogenes c-fos, c-myc, k-ras and apoptosis genes Caspase-3, Caspase-8 and Caspase-9 decreased, the expression level of tumor suppressor gene p53 increased in the p38MAPK gene silencing cells group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Conclusion: PM(2.5) has effects on the expression of oncogenes, tumor suppressor genes and apoptotic genes in L02 hepatocytes, while p38MAPK gene silencing can inhibit the effects of PM(2.5) on L02 hepatocytes.

Abstract
Objective: To construct the c-myc gene silenced hepatocytes, study the effect of c-myc gene silence on expression of oncogenes and apoptosis genes in hepatocytes treated with PM2.5. Methods: According to the c-myc gene mRNA sequence provided by GenBank, three interfering sequences were designed and synthesized, the recombinant lentiviral vector was transfected into L02 hepatocytes. The real-time quantitative PCR and western blotting were used to identify the effect of c-myc gene silencing. L02 cells and c-myc gene silenced cells were used as experimental subjects. The normal L02 cells and c-myc silenced cells were treated with 50 μg/ml PM(2.5) water soluble solution, 10 μM positive control Cr(6+) and a blank control, the treatment period was 24 h. The mRNA levels of oncogenes (c-myc, c-fos, k-ras, p53) and apoptotic genes (Caspase-3, Caspase-8, Caspase-9) were detected by real-time PCR. The protein levels of oncogenes and apoptotic genes were detected by western blotting. Results: The mRNA level and protein level of c-myc decreased by 81% and 70% in c-myc silenced cells when compared with the normal L02 hepatocytes, the above results indicate that c-myc gene silenced cells were successfully constructed. After c-myc silenced cells were treated with PM2.5 water soluble solution, The mRNA levels of c-myc, c-fos, and k-ras decreased by 84.1%, 45.4%, and 54.6% (P<0.05) , p53 increased by 192.9% (P<0.05) , and the expression of Caspase-3, Caspase-8, and Caspase-9 decreased by 24.4%, 36.1%, 60.9% (P<0.05) . In the Cr(6+) positive control group, the expression of c-myc, c-fos, and k-ras decreased by 72.1%, 82.2%, and 54.0% (P<0.05) , p53 increased by 250.0% (P<0.05) , the expression of Caspase-3, Caspase-8, and Caspase-9 decreased by 34.6%, 36.0%, 68.9% (P<0.05) , respectively, when compared with the normal L02 hepatocytes (P<0.05) . Western blotting results showed that the protein levels of c-myc and c-fos increased, p53 decreased after PM(2.5) exposure; the protein levels of Caspase-3, Caspase-8, Caspase-9 increased after PM(2.5) exposure (P<0.05) . When in comparison with the c-myc silenced group, the protein levels of c-myc and c-fos decreased, p53 protein increased in PM(2).5 exposed group (P<0.05) . Conclusion: c-myc gene silenced cells were successfully constructed in this paper. PM(2.5) could promote the expression of oncogenes and apoptotic genes in L02 cells, and c-myc gene silencing can inhibit the expression of oncogenes and apoptotic genes after PM(2.5) treatment in L02 cells.

Abstract
This study sought to assess whether the objective response (OR, including complete response and partial response) of first-line chemotherapy can predict overall survival (OS) for patients with metastatic triple-negative breast cancer (mTNBC) in both clinical trial and a real-world setting. The survival predictable parameters were assessed in two independent cohorts, the training cohort of 236 patients as part of a phase 3 trial (CBCSG006, Trial registration number NCT0128762) and the validation cohort of 360 patients from the real-world setting. Univariable and multivariable Cox proportional hazard models were applied to explore associations with progression-free survival and OS in the training cohort and then in the validation cohort. OR (OR vs non-OR, HR, 0.438, p<0.001) together with Eastern Cooperative Oncology Group (ECOG) performance status, disease-free survival, number of metastatic organ sites and platinum-based chemotherapy used as first-line chemotherapy were observed to be independent prognostic factors for progression-free survival (PFS), and OR (OR vs non-OR, HR, 0.602, p=0.002) together with ECOG score, disease-free survival, number of metastatic organ sites and previous anthracycline and/or taxane treatment were observed to be independent predictive factors for OS in the training cohort. These predictors were confirmed in the validation cohort. For OR and non-OR group, median OS was 23.72 and 13.83 months in the training cohort (HR, 0.637, p=0.002), and 21.95 and 13.80 months in the validation cohort (HR, 0.608, p<0.001), respectively. By adding OR in the OS predictors, the concordance index (C-index) improved from 0.622 to 0.645 in the training cohort and 0.653 to 0.675 in the validation cohort. PFS and OS of mTNBC can be predicted by OR status with any regimen of first-line chemotherapy in an independent prospective clinical trial and a real-world setting. Therefore, TNBC, not like other subtypes of breast cancer, may be in need of combination chemotherapy or intense chemotherapy to achieve a high response rate for survival.

Abstract
Non-alcoholic fatty liver disease and alcohol (ethanol)-related liver disease is a global epidemic of chronic liver disease and the main cause of fatty liver. Non-alcoholic fatty liver patients sometimes ingest different types of alcohol. Therefore, when obesity coexist with alcohol consumption, it is more difficult to diagnose the cause of fatty liver. The amount of alcohol consumption and alcohol drinking pattern and chronic liver injury, type 2 diabetes mellitus, cardiovascular disease and other metabolic-related diseases may have J-type correlation; that is to say, a light to moderate amount of alcohol consumption may bring certain benefits to the above diseases, but excessive alcohol consumption may promote the development of obesity, aggravate liver disease, metabolic abnormalities, and increase the risk of tumors. Screening for metabolic-related disease risk should be considered in addition to the assessment of changing liver lesions when obesity coexists with alcohol consumption. Changing bad living habits, losing weight and abstaining from alcohol are still the basis of treating fatty liver and metabolic disorders. Carefully selecting patients and communicating with them about the risk and benefit of drugs are important indicators of drug therapy. Patients with end-stage liver disease can be considered for liver transplantation and postoperative lifestyle improvement should be emphasized.

Abstract
Objective: To quantitate the association between birth weight and phenotypes of physical indicators in adulthood, i.e. BMI and waist circumference (WC) and to what degree genetic or environmental factors affect birth weight-obesity association. Methods: A total of 6 623 gender matched twin pairs aged 25 to 79 years were recruited through the Chinese National Twin Registry. The twins reported their own birth weight, current height and weight, and WC using a self-administered questionnaire. BMI was calculated according to the self-reports of body height and weight. Within twin-pair design was used to quantitate the association between birth weight and phenotypes related to obesity while bivariate structural equation models were used to decompose the phenotype correlation. Results: After adjusted for multiple factors, twin-pair analyses within monozygotic (MZ) showed that, on average, a 1.0 kg increase in birth weight corresponded to an increase of 0.33 kg/m(2) in BMI and 0.95 cm in WC in adulthood (P<0.001). Bivariate structural equation models showed significant positive unique environmental correlation between birth weight and the two obesity-related phenotypes. Conclusion: The study supported the role of twin-specific supply line factors on relationship between birth weight and physical indicators in adulthood.

Abstract
Objective: To investigate the impact of heterotopic ossification (HO) after cervical disc replacement (CDR) on clinical outcome and radiological outcome of adjacent segment. Methods: The data of patients underwent single-level Prestige-LP CDR between January 2008 and March 2014 in West China Hospital with a minimum 36 months of follow-up were retrospectively analyzed in this study. The incidence of HO, whether it affected clinical outcome, and its impact on adjacent segment intervertebral disc height (IDH), range of motion (ROM) and adjacent segment degeneration were observed. The data were compared with independent sample t test between the two groups. Results: Ninety-two patients were included in this study, including 48 males and 44 females, the mean age was (44±8) years, and the mean follow-up was (62±23) months. At the final follow-up, 34 patients developed HO after CDR, but the incidence of Grade 4 HO was 7.6%. In both of the HO and non-HO groups, clinical outcomes at the final follow-up were all significantly improved when compared to those before the operation. And there was no significant differences in any clinical indexes between the HO and non-HO groups. The adjacent segment IDH before operation and at the final follow-up in the HO group and non-HO group were similar(t=0.596, 0.825 and t=0.877, 0.644, all P>0.05). The preoperative adjacent segment ROM of HO group was similar with that in non-HO group(t=0.056, 0.709, both P>0.05), but the adjacent segment ROM in HO group was higher than that in the non-HO group at the final follow-up (upper adjacent segment: 10.0°±2.0° vs 9.0°±1.3°; lower adjacent segment: 10.2°±1.9° vs 8.8°±1.3°, t=2.824, 4.022, both P<0.05). The incidence of adjacent segment degeneration of HO group was higher than that of non-HO group at the final follow-up(41.2% vs 19.0%, χ(2)=5.343, P<0.05). Conclusions: HO is a common phenomenon in the long-term follow-up after the CDR operation with Prestige LP prosthesis, but HO does not affect the improvement of clinical outcome. HO after CDR might be one of important risk factors accelerating adjacent segment degeneration.

Abstract
Background CBCSG006 trial reported the superior efficacy of cisplatin plus gemcitabine (GP) regimen than paclitaxel plus gemcitabine (GT) regimen as first-line treatment of metastatic triple-negative breast cancer (mTNBC). This study focused on the updated survival data and the explorations of potential biomarkers for efficacy. Patients and methods Germ-line mutations of homologous recombination (HR) panel, BRCA1/2 included, were evaluated in 55.9% (132/236) patients. PD-L1 expression was evaluated in 48.3% (114/236) patients. A nonparametric sliding-window subpopulation treatment effect pattern plot (STEPP) methodology was used to analyze the absolute survival benefits. All statistical tests were two-sided. Results Median progression-free survival (PFS) was 7.73 [95% confidence interval (CI) 6.46-9.00] months for GP arm and 6.07 (95% CI 5.32-6.83) months for GT arm (P = 0.005). No significant difference in overall survival (OS) was observed. There was significant interaction between HR status and treatment for PFS and status of HR deficient significantly correlated with higher objective response rate (ORR) and longer PFS in GP arm than in GT arm (71.9% versus 38.7%, P = 0.008; 10.37 versus 4.30 months, P = 0.011). There was no significant interaction between germ-line BRCA1/2 (gBRCA1/2) status and treatment for PFS. Patients with gBRCA1/2 mutation had numerically higher ORR and prolonged PFS in GP arm than in GT arm (83.3% versus 37.5%, P = 0.086; 8.90 versus 3.20 months, P = 0.459). There was no significant interaction between PD-L1 status and treatment for PFS, and no significant differences in ORR, PFS or OS between two arms regardless of PD-L1 status. In STEPP analysis, patients with lower composite risks had more absolute benefits in PFS than those with higher composite risks. Conclusions GP regimen has superior efficacy than GT regimen as first-line chemotherapy for mTNBC patients. Germ-line mutations of BRCA1/2 and HR panel are possible biomarkers for better performance of cisplatin-based regimens. A composite risk model was developed to guide patient selection for GP treatment in TNBC patients. Trial registration ClinicalTrials.gov, NCT01287624.

Abstract
Objective: To investigate the impact of implant height on the morphology of cervical facet joints in artificial cervical disc replacement (ACDR). Methods: A finite element model of the cervical spine from C(2) to C(7) was constructed. The surgical processes of ACDR were simulated by insertion of 5 mm, 6 mm or 7 mm Prestige-LP artificial cervical discs. The morphological changes of cervical facet joints were recorded in terms of facet overlap distance, facet overlap area and facet angle. Results: The normal height Prestige-LP cervical disc could restore the natural status of the cervical spine. Compared with the intact condition, the model with ≥2 mm height implant would reduce the overall range of motion (ROM) by 19.2% in flexion, 19.4% in extension, 18.4% in lateral bending and 19.0% in axial rotation. Besides, the ROM at the surgical level reduced by 15.8% in flexion, 15.4% in extension and lateral bending and 19.0% in rotation. The upper and lower adjacent levels (C(4/5) and C(5/6)) showed more obvious changes in ROM, which reduced by 26.8% and 26.5% in flexion, 26.6% in extension, 26.5% and 26.4% in lateral bending, and 26.4% and 26.3% in rotation, respectively. The reduction of facet overlap distance, facet angle and facet overlap area with the ≥2 mm height artifact was 9.6%, 30.7%, and 17.9% respectively at the upper adjacent level, and 22.3%, 35.3% and 28.2% respectively at the surgical level, compared with the intact model.The morphology of facet joints at the lower adjacent level were slightly changed. Conclusion: The implant height selection in ACDR should be in accordance with the physiological intervertebral disc height. Artifact with ≥2 mm in height would obviously change the morphology of facet joints, thus should not be used in clinical practice.

Abstract
Objective: To investigate the effect of global end-diastolic volume index (GEDI)-guided fluid resuscitation on the prognosis of patients with chronic heart failure and septic shock. Methods: This study was a prospective randomized controlled study. Consecutive eligible patients were divided into 2 groups according to the random number table method: control group (n=21) and experimental group (n=20). On the basis of routine treatment, patients in the control group received early goal-directed therapy until the central venous pressure (CVP) reaching 8-12 mmHg (1 mmHg=0.133 kPa), mean arterial pressure reaching over 65 mmHg, urine volume reaching over 0.5 ml·kg(-1)·h(-1), and central venous oxygen saturation reaching more than 70%. On the basis of routine treatment, patients in the experimental group were monitored continuously on cardiac output with pulse indication and fluid resuscitation guided by volume index GEDI. The GEDI should be maintained on the range of 680-800 ml/m(2). The remaining resuscitation goals were the same as control group. General clinical data of the two groups were collected at admission. Negative fluid balance onset time, duration of mechanical ventilation, ICU mortality and 28-day mortality were compared between the two groups. The outcomes were recorded as listed: start time of negative fluid balance, duration of mechanical ventilation, mortality in ICU and 28-day mortality. Results: There was no significant difference in age, sex, weight, APACHE Ⅱ score, SOFA score and NYHA functional class score between the two groups (all P>0.05). The negative liquid balance onset time in the control group was 3.5 (2.5, 4.0) days, which was significantly longer than that in the experimental group (2.6 (2.0, 3.0) days,U=115.0, P=0.012). The duration of mechanical ventilation was 355 (118, 552) hours in the control group, which was significantly longer than that in the experimental group (132 (36.75, 233.3) hours, U=130, P=0.038). The ICU mortality was 38.1% (8/21) in the control group, tended to be higher than that in the experimental group (20.0%(4/20), χ(2)=1.620, P=0.203). The 28-day mortality was 42.9% (9/21) in the control group, similar as in the experimental group (25.0%(5/20), χ(2)=1.482,P=0.477). Conclusion: Fluid resuscitation guided by volume index (GEDI) may improve the prognosis of patients with chronic heart failure complicated with septic shock.

Abstract
Objective: To construct 3β-HSD gene shRNA lentivirus interference vecto, then transfect into human MCF-7 cells, and construct cell line with 3β-HSD gene silencing, finally to study the effects of 3β-HSD on apoptosis induced by di- (2-ethylhexyl) phthalate (DEHP) . Methods: According to the mRNA sequence of 3β-HSD gene provided by GenBank, three interference sequences were designed and connected to PLVX-shRNA2-puro after annealing. The recombinant lentivirus vector was transfected into 293FT cells, the virus supernatants were collected and infected with MCF-7 cells. After puromycin screening, MCF-7 cells with 3β-HSD gene silencing were constructed. The cells with 3β-HSD gene silencing were identified by real-time quantitative PCR and western blot. Then the 3β-HSD gene silencing cells and MCF-7 cells were treated at various doses of DEHP for 24 hours to detect the gene expression and protein expression of apoptosis genes including Bax, Caspase-3 and Caspase-8. Results: The interference sequence of 3β-HSD gene inserted into lentivirus vector PLVX-shRNA2-puro is consistent with the designed sequence. 3β-HSD gene expression level in MCF-7 cells with 3β-HSD gene silencing was 77% lower than than that of control MCF-7 cells. 3β-HSD protein level in MCF-7 cells with 3β-HSD gene silencing was 74% lower than that of control MCF-7 cells. After DEHP treatment in MCF-7 cells with 3β-HSD gene silencing and control MCF-7 cells, qRT-PCR results showed that Bax gene expression levels increased by 28%-54%, Caspase-3 gene increased by 13%-49%, Caspase-8 gene increased by 21%-70% in MCF-7 cells when compared with the control group. Additionally, in the 3β-HSD gene silencing cells, Bax gene expression level decreased by 11%-28%, Caspase-3 gene expression decreased by 12%-23%, Caspase-8 gene expression decreased by 11%-34%, compared with the same treatment group of MCF-7 cells. Western blot results showed that Bax protein expression level increased by 28%-61%, Caspase-3 protein expression level increased by 40%-48%, Caspase-8 protein increased by 31%-84% in MCF-7 cells when compared with the control group. In 3β-HSD gene silencing cells, Bax protein expression level increased by 11%-27%, Caspase-3 protein increased by 21%-40%, Caspase-8 protein increased by 12%-25%, compared with the same treatment group of MCF-7 cells. Conclusion: The stable 3β-HSD gene silencing cell line are successfully constructed in this study. DEHP can induce increased expression of apoptotic gene and protein. Silencing of 3β-HSD gene can inhibit the activation of apoptotic gene by DEHP in a certain degree.

Abstract
Objective: To analyze the heritability of diabetes among the Chinese twin adults. Methods: A total of 10 253 same-sex twin pairs aged 25 years and older, were selected from the Chinese National Twin Registry (CNTR) program. Heritability of diabetes was calculated by using the structural equation model. Results: After adjusted for age and gender, the overall heritability rates of diabetes were 0.41 (0.15-0.75), 0.83 (0.72-0.91) and 0.34 (0.04-0.73) in the <45 and ≥45 years twin pairs, respectively. After adjusted for age, rates of heritability appeared as 0.37 (0.05-0.78) and 0.88 (0.79-0.94) in men and women, respectively. Conclusions: Diabetes is affected by both genetic and environmental factors. The genetic effect of diabetes seemed stronger on female than that on male twins but was dying down along with ageing.

Abstract
Intravenous regional anesthesia (IVRA; Bier block) is commonly used to anesthetize an extremity for surgery. Limitations of the procedure include pain from the required tourniquet, the toxicity that can occur from systemic release of local anesthetics, and the lack of postoperative pain relief. We hypothesized that the nanoencapsulation of the local anesthetic would prolong local anesthesia and enhance safety. Here, we developed an ∼15 nm micellar bupivacaine formulation (M-Bup) and tested it in a rat tail vein IVRA model, in which active agents were restricted in the tail by a tourniquet for 15 min. After tourniquet removal, M-Bup provided local anesthesia for 4.5 h, which was two times longer than that from a larger dose of free bupivacaine. Approximately 100 nm liposomal bupivacaine (L-Bup) with the same drug dose as M-Bup did not cause anesthesia. Blood levels of bupivacaine after tourniquet removal were lower in animals receiving M-Bup than L-Bup or free bupivacaine, demonstrating enhanced safety. Tissue reaction to M-Bup was benign.

Abstract
Objective: To investigate the relationship between body mass index (BMI) and all-cause mortality in hypertensive population. Methods: All participants were selected from a prospective cohort study based on a rural population from Henan province, China. Cox proportional hazards regression models were used to estimate the associations of different levels of BMI stratification with all-cause mortality. Restricted cubic spline models were used to detect the dose-response relation. Results: Among the 5 461 hypertensive patients, a total of 31 048.38 person-years follow-up was conducted. The median of follow-up time was 6 years, and 589 deaths occurred during the follow-up period. Compared to normal weight group (18.5 kg/m(2)<BMI<24.0 kg/m(2)) the multivariate-adjusted hazard ratios for all-cause mortality associated with BMI levels (<18.5 kg/m(2), 24-28 kg/m(2), and ≥28 kg/m(2)) were 0.83 (95%CI: 0.37-1.87), 0.81 (95%CI: 0.67-0.97), and 0.72 (95%CI: 0.56-0.91), respectively. The dose-response analysis showed a nonlinear, reverse "S" shaped relationship (non-linearity P<0.001). Conclusion: Overweight or obese might have a protective effect on all-cause mortality in hypertensive population, which supports the "obesity paradox" phenomenon.

Abstract
The efficacy of tetrodotoxin (TTX), a very potent local anesthetic, is limited by its poor penetration through barriers to axonal surfaces. To address this issue, we encapsulated TTX in hollow silica nanoparticles (TTX-HSN) and injected them at the sciatic nerve in rats. TTX-HSN achieved an increased frequency of successful blocks, prolonged the duration of the block, and decreased the toxicity compared to free TTX. In animals injected with fluorescently labeled HSN, the imaging of frozen sections of nerve demonstrated that HSN could penetrate into nerve and that the penetrating ability of silica nanoparticles was highly size-dependent. These results demonstrated that HSN could deliver TTX into the nerve, enhancing efficacy while improving safety.

Abstract
Sheep are an important source of fiber production. Fibroblast growth factor 5 (FGF5) is a dominant inhibitor of length of the anagen phase of the hair cycle. Knockout or silencing of the gene results in a wooly coat in mice, donkeys, dogs, and rabbits. In sheep breeding, wool length is one of the most important wool quality traits. However, traditional breeding cannot accurately and efficiently mediate an advanced genotype into the sheep genome. In this study, we generated 3 knockout sheep via the 1-step clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 system. Sequencing analysis confirmed that mutations in the gene existed in all germ lines of 3 founders: besides the intact sequence, 3 kinds of deletions in the gene (including 5, 13, and 33 bp) were detected. The changes in the primary and senior structure of the FGF5 protein due to the 3 deletions in founders suggested that the FGF5 protein was dysfunctional. In addition, the expression level of intact mRNA in heterozygous individuals decreased compared with the wild types ( < 0.01). Functionally, we discovered that wool length in founders was significantly longer than in wild types ( < 0.05). Collectively, the knockout sheep with the longer wool length phenotype will provide an efficient way for fast genetic improvement of sheep breeding and promote the development of wool industry.

To analyze the nursing effect on the respiratory function of thoracotomy patients, sixty thoracotomy hospitalized patients were studied. The subjects were divided into a normal group (A) and an observation group (B). The patients in group A received routine nursing only, while those in group B received chest physiotherapy as well as routine nursing. Afterwards, the respiratory function indicators of the two groups were compared and a data analysis was performed. The results showed that the partial pressure of oxygen (PO2) value of the patients in group B was greater than that of the patients in group A while the partial pressure of carbon dioxide (PCO2) value in group B was smaller than that in group A, and there was a significant difference between the two groups (p less than 0.05). The vital capacity under normal circumstances and forced breathing of group B were greater than that of group A and the difference was statistically significant (p less than 0.05). The incidence of complications (atelectasis, respiratory infections, pleural effusion) was statistically significant between the two groups (p less than 0.05). The degree of autonomic respiratory dysfunction in group B was lower than that in group A, and there was a significant difference (p less than 0.05), suggesting that the respiratory function in patients receiving chest physiotherapy improved significantly.

Abstract
Hydrocarbon polymers, O-containing, F-containing and Cl-containing polymers are comprehensively studied by Coincidence Doppler Broadening Spectroscopy (CDBS). It is shown that for polymers with different chemical structure, CDBS results can effectively distinguish polar groups CO, CCl, and CF. For polymers with similar chemical structure, the intensity of the element-specific peak in the CDBS ratio curve is dependent not only on the fraction of free positrons, but also on the content of characteristic atom in polymer repeated unit, and the polarity of the polymer molecule. For polymers containing several different polar groups, such as PCTFE (CF & CCl) and PFA (CF & CO), whether the element-specific peak appears or not depends on the amount of the polar groups and its positron capture ability. This work may provide insights into potential applications of CDBS for studying complex polymer systems.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has become the most important liver disease in the world and its prevalence rate still tends to increase. However, there are still no effective drugs so far. The complex and dynamic interactions between multiple effects/mediators in the pathophysiology of NAFLD provide new insights and help with stratification and redefinition of clinical phenotypes and evaluation of disease susceptibility and multiplicity of progression. They may also provide new targets for future treatment. Therefore, research on the pathophysiology of NAFLD is imperative. Alcoholic liver disease is a great harm to health and an important cause of end-stage liver disease. Some progress has been made in the research on alcoholic liver disease around the world in 2016. This article reviews the research advances in alcoholic liver disease in 2016 from the aspects of epidemiology, pathogenesis, diagnostic and therapeutic methods, and prognosis.

Abstract
INSTRUCTION Anterior cervical discectomy and fusion (ACDF) is a well-accepted surgical management strategy for radiculopathy and/or myelopathy. However, complications sometimes required subsequent surgery at the operated and adjacent levels. Artificial cervical disc replacement (ACDR) has been accepted as the most extensive non-fusion procedure and is designed to preserve motion. However, some specific complications can result in subsequent surgery, thus, attracting the attention of investigators. HYPOTHESIS Compared with ACDF, ACDR had a lower subsequent surgery rates at both operated and adjacent levels after a minimum of four-years of follow-up. MATERIAL AND METHODS A meta-analysis was performed with articles published prior to February 2016. Only randomized controlled trials that reported a minimum of 4 years of follow-up with regard to the rates of subsequent surgeries after ACDR compared with ACDF were included in this study. Two reviewers independently screened the articles and data following the PRISMA statement. RESULTS Our data showed that the pooled overall rate of subsequent surgery at the operated level and adjacent levels was lower in the ACDR group (7.4%) than in the ACDF group (16.8%) (P=0.0006). For subsequent surgery at the operated level, patients who received ACDR had a lower rate of subsequent surgery than patients who received ACDF (P<0.0001). With respect to the adjacent level, ACDR also had fewer subsequent surgeries compared with ACDF (P<0.0001). CONCLUSION ACDR had significantly fewer subsequent surgical interventions compared with ACDF, However, a review of the literature showed that there were an insufficient number of studies with respect to subsequent surgery with a minimum of 4 years of follow-up. Hence, longer-term, multicenter studies are needed for better evaluation of the rate of subsequent surgery after ACDR. LEVEL OF EVIDENCE Level I, meta-analysis of high-powered prospective randomized trials.

Abstract
OBJECTIVE To investigate the association between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and the incidence risk of type 2 diabetes mellitus (T2DM). METHODS In total, 20 194 participants ≥18 years old were selected randomly by cluster sampling from two township (town) of the county in Henan province from July to August of 2007 and July to August of 2008 and the investigation included questionnaires, anthropometric measurements, fasting plasma glucose, and lipid profile examination were performed at baseline; 17 236 participants were enrolled in this cohort study. 14 720 (85.4%) were followed up from July to August 2013 and July to October 2014. Finally, 11 643 participants (4 301 males and 7 342 females) were included in this study. Incidence density and Cox proportional hazards regression models were used to evaluate the risk of T2DM associated with baseline BMI, WC, WHtR, and their dynamic changes. RESULTS After average of 6.01 years following up for 11 643 participants, 613 developed T2DM and the incidence density was 0.89 per 100 person-years. After adjusted for baseline sex, age, smoking, drinking, family history of diabetes, as well as the difference of fasting plasma-glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), diastolic blood pressure (DBP) between baseline and follow-up, Cox Proportional-Hazards regression analysis indicated that T2DM risk of baseline BMI overweight group, BMI obesity group, abnormal WC group and abnormal WHtR group were significantly higher than that of the corresponding baseline normal groups , and the incidence risk of T2DM reached the highest for those whose baseline BMI, WC and WHtR were all abnormal, the corresponding HR (95%CI) were 2.05 (1.62-2.59), 3.01 (2.33-3.90), 2.34 (1.89-2.90), 2.88 (2.21-3.74), 3.32 (2.50-4.40), respectively. Whether baseline BMI/WC was normal or not, T2DM risk increased if baseline WHtR was abnormal, and the HR (95%CI) of baseline normal BMI/abnormal WHtR group, baseline abnormal BMI/abnormal WHtR group, baseline normal WC/abnormal WHtR group, baseline abnormal WC/abnormal WHtR group were 1.88 (1.29-2.74), 3.08 (2.34-4.05), 2.15(1.53-3.00), 3.22 (2.45-4.23), respectively. The analysis for dynamic changes of BMI, WC, and WHtR indicated that in baseline normal WC or WHtR group, T2DM risk increased when baseline normal WC or WHtR developed abnormal at follow-up, and the corresponding HR (95%CI) were 1.79 (1.26-2.55), 2.12(1.32-3.39), respectively. In baseline abnormal WC or WHtR group, T2DM risk decresed when baseline abnormal WC or WHtR reversed to normal at follow-up, and the corresponding HR (95%CI) were 2.16 (1.42-3.29), 2.62 (1.63-4.20), respectively. CONCLUSION BMI, WC, and WHtR were associated with increased T2DM risk. The more abnormal aggregation of BMI, WC, and WHtR presents, the higher T2DM risk was. T2DM risk could be decreased when abnormal WC or WHtR reversed to normal.

Abstract
OBJECTIVE To analyze the influences of genetic and environmental factors on smoking behavior, smoking cessation and onset age of smoking less than 20 years in male twin adults. METHODS A face-to-face questionnaire was conducted to collect data from 6 458 pair male twins aged ≥25 years registered in 9 provinces(municipality)in China. The heritability of three smoking related behaviors were calculated by using structural equation models. RESULTS The ACE models were the best models of the three dimensions of smoking, i.e. smoking behavior, smoking cessation and onset age of smoking less than 20 years for male twins, and the corresponding heritability of these behaviors were 0.26(0.19-0.34), 0.27(0.19-0.37)and 0.05(0.00-0.14), respectively. When adjusted for area and age, the heritability of these three behaviors were 0.26(0.19-0.34), 0.31(0.00-0.74)and 0.05(0.00-0.14), respectively. CONCLUSIONS All the three smoking related behaviors were affected by genetic factors, but environment factors had more effect on them. For smoking cessation, the heritability was highest, but the influence of environmental factors was lowest. Meanwhile, for onset age of smoking, the influence of environmental factors was highest.

Abstract
OBJECTIVE To provide a noninvasive type 2 diabetes mellitus (T2DM) prediction model for a rural Chinese population. METHODS From July to August, 2007 and July to August, 2008, a total of 20 194 participants aged ≥18 years were selected by cluster sampling technique from a rural population in two townships of Henan province, China. Data were collected by questionnaire interview, anthropometric measurement, and fasting plasma glucose and lipid profile examination. A total 17 265 participants were followed up from July to August, 2013 and July to October, 2014. Finally, 12 285 participants were selected for analysis. Data for these participants were randomly divided into a derivation group (derivation dataset, n= 6 143) and validation group (validation dataset, n=6 142) by 1∶1, respectively. Randomization was carried out by the use of computer-generated random numbers. A Cox regression model was used to analyze risk factors of T2DM in the derivation dataset. A T2DM prediction model was established by multiplying β by 10 for each significant variable. After the total score was calculated by the model, analysis of the receiver operating characteristic (ROC) curve was performed. The area under the ROC curve (AUC) was used for evaluating model predictability. Furthermore, the model's predictability was validated in the validation dataset and compared with the Finnish Diabetes Risk Score (FINDRISC) model. RESULTS A total 779 of 12 285 participants developed T2DM during the 6-year study period. The incidence rate was 6.12% in the derivation dataset (n=376) and 6.56% in the validation dataset (n=403). The difference was not statistically significant (χ(2)=1.00, P=0.316). A total of four noninvasive T2DM prediction models were established using the Cox regression model. The ROCs of the risk score calculated by the prediction models indicated that the AUCs of these models were similar (0.67-0.70). The AUC and Youden index of model 4 was the highest. The optimal cut-off value, sensitivity, specificity, and Youden index were scores of 25, 65.96%, 66.47%, and 0.32, respectively. Age, sleep time, BMI, waist circumference, and hypertension were selected as predictive variables. Using age<30 years as reference, β values were 1.07, 1.58, and 1.67 and assigned scores were 11, 16, and 17 for age groups 30-44, 45-59, and ≥60 years, respectively. Using sleep time<8.0 h/d as reference, the β value and assigned score were 0.27 and 3, respectively, for sleep time ≥10.0 h/d. Using BMI 18.5-23.9 kg/m(2) as reference, β values were 0.53 and 1.00 and assigned scores 5 and 10, respectively, for BMI 24.0-27.9 kg/m(2), and ≥28.0 kg/m(2). Using waist circumference <85 cm for males/< 80 cm for females as reference, β values were 0.44 and 0.65 and assigned scores 4 and 7, respectively, for 85 cm ≤ waist circumference <90 cm for males/80 cm≤ waist circumference <85 cm for females, and waist circumference ≥90 cm for males/≥85 cm for females. Using nonhypertension as reference, the respective β value and assigned score were 0.34 and 3 for hypertension. The AUC performance of this model and the FINDRISC model was 0.66 and 0.64 (P=0.135), respectively, in the validation dataset. CONCLUSION Based on this cohort study, a noninvasive prediction model that included age, sleep time, BMI, waist circumference, and hypertension was established, which is equivalent to the FINDRISC model and applicable to a rural Chinese population.

Abstract
In order to conduct lunar surface mineral composition studies and content analysis, the Visible and Near-infrared Imaging Spectrometer (VNIS), one of the scientific payloads of the Chang'E 3 Yutu rover, has been developed to detect lunar surface objects and to obtain their reflectance spectra and geometric images. This is achieved with a 45° visual angle and at a height of 0.69 m. VNIS is equipped with a lunar surface calibration function, and the spectral range is 0.45-2.40 μm with a spectral resolution of 2-12 nm. It is capable of synchronously acquiring the full spectrum of lunar surface objects and in situ calibration. Here, we describe the VNIS and explain the preliminary results of the lunar surface exploration and calibration, which provides valuable information for scientific data processing and applications.

Abstract
A 948-bp sequence of the UL2 gene was amplified from the pseudorabies virus (PRV) Becker strain genome using polymerase chain reaction, and the gene identity was confirmed through further cloning and sequencing. Bioinformatic analysis indicated that the PRV UL2 gene encodes a putative polypeptide with 315-amino acid residues. Its encoding protein, designated UL2, has a conserved uracil-DNA glycosylase (UDG)_F1 domain, which is closely related to the herpesvirus UDG family and is highly conserved among its counterparts encoded by UDG genes. Multiple nucleic acid and amino acid sequence alignments suggested that the product of PRV UL2 has a relatively higher homology with UL2-like proteins of Alphaherpesvirinae than that of other subfamilies of Herpesviridae. In addition, phylogenetic analysis showed that PRV UL2 had a close evolutionary relationship with members of Alphaherpesvirinae, especially members of the genus Varicellovirus of bovine herpesvirus 1 and bovine herpesvirus 5. Antigen prediction indicated the presence of several potential B-cell epitopes in PRV UL2. In addition, secondary structure and 3-dimensional structure prediction revealed that PRV UL2 consisted predominantly of an α-helix. Taken together, these results provide molecular biological insight for the further study of the function and mechanism of UL2 during PRV infection.

Abstract
Pseudorabies virus (PRV) early protein UL54 is a homolog of herpes simplex virus 1 immediate-early protein ICP27, which is a multifunctional protein essential for the virus replication. However, the precise role of the PRV UL54 protein in the virus life cycle is still poorly understood. To shed more light on this problem, we considered it essential to have available an antiserum specifically detecting this protein. Since it was known that a full-length UL54 protein is a too big molecule for efficient expression in prokaryotic systems, it was truncated from 1 to 66 N-terminal amino acids, fused to EYFP-His tag and expressed in Escherichia coli through an appropriate expression vector. The truncated protein was purified by Ni-NTA affinity chromatography and used for raising an antiserum in rabbits. Western blot analysis showed that this antiserum specifically recognized the purified truncated as well as full-length UL54 protein in PRV-infected cells. Immunofluorescence assay confirmed the latter finding and also demonstrated localization of this protein first in nucleoli and later in whole nuclei of PRV-infected cells. These results indicate that the prepared antiserum could serve as a valuable tool in further studies of PRV UL54 protein function.

Abstract
We report on the characterization of modifications in fused silica after exposure to low fluence (2 J/cm2) 355 nm laser at repetition frequencies of 1 Hz, 5 Hz and 10 Hz. Synchrotron based XRF spectroscopy is employed to study concentration variation of metal inclusions in the surface layer. Positron annihilation lifetime spectroscopy is used to probe atomic size defects variation in bulk silica. FT-IR is used to characterize changes of bond length and angle of Si-O-Si covalent bond of irradiated silica. Compared to the basic frequency, the big loss of cerium and iron concentration, the size enlargement of vacancy cluster and the decrease of Si-O-Si covalent bond length after 10 Hz laser irradiation are illustrated by our data. These tiny modifications provide important data to investigate laser damage mechanism.

Abstract
BACKGROUND Aortic stenosis (AS) is a common progressive disease. Statins have been hypothesized to delay its progression via pleiotropic mechanisms. However, results of clinical trials focusing on statin therapy in AS patients have been controversial. OBJECTIVE To analyse and summarize the findings in recent statin trials and to discuss the rationale of statin usage in AS populations. METHODS A comprehensive database search was conducted by two independent reviewers. Controlled trials that compared progression of AS between statin and non-statin therapy published before 31 December 2008 were included. Data were extracted for meta-analysis, to estimate overall effects, if available. Factors that contributed to heterogeneities among the trials were analysed. RESULTS The meta-analysis included nine trials with a total of 2947 patients. Statin therapy displayed an overall statistically significant effect on delaying AS progression. The weighted mean difference (statin vs. control) of annual increase of peak aortic-jet velocity was -0·12 m/s (95% confidence interval -0·22 to -0·03); the increase of mean transaortic pressure gradient was -1·64 mmHg per year (-3·27 to -0·01); Heterogeneity-analysis suggested that the baseline risk factors and characteristics of the patients, the use of different statins, and the time point to initiate statin therapy, may be important considerations when interpreting the result of individual studies. CONCLUSION Although the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial reported negative results in delaying AS progression in low-risk patients, the potential benefits of statins in those with multiple risk factors and their value in preventing future coronary events call for further investigation of different categories of AS patients.

Abstract
BACKGROUND AND OBJECTIVE The mechanism by which periodontal pathogens dominate at disease sites is not yet understood. One possibility is that these late colonizers antagonize the quorum-sensing systems of early colonizers and render those early colonizers less resistant to environmental factors. In this study, we utilized Streptococcus mutans, a well-documented oral Streptococcus with many quorum-sensing-dependent properties, as an example of an earlier colonizer antagonized by periodontal pathogens. MATERIAL AND METHODS In this study, S. mutans NG8 and S. mutans LT11 were used in experiments assessing transformation, and S. mutans BM71 was used in experiments investigating bacteriocin production. The effects of the periodontal pathogens Porphyromonas gingivalis and Treponema denticola on these competence-stimulating peptide-dependent properties were evaluated in mixed-broth assays. RESULTS Both P. gingivalis (either live bacteria or membrane vesicles) and T. denticola antagonized transformation in S. mutans NG8 and LT11. The production of bacteriocin by S. mutans BM71 was also inhibited by P. gingivalis and T. denticola. Boiling of these late colonizers before addition to the broth cultures abolished their ability to inhibit S. mutans transformation and bacteriocin production. P. gingivalis and T. denticola inactivated S. mutans exogenous competence-stimulating peptide, whereas the boiled bacteria did not. CONCLUSIONS This study demonstrated that periodontal pathogens antagonize S. mutans quorum-sensing properties. This may render S. mutans less virulent and less resistant to environmental antibacterial factors.

Abstract
We demonstrate, both theoretically and experimentally, that cation vacancy can be the origin of ferromagnetism in intrinsic dilute magnetic semiconductors. The vacancies can be controlled to tune the ferromagnetism. Using Li-doped ZnO as an example, we found that while Li itself is nonmagnetic, it generates holes in ZnO, and its presence reduces the formation energy of Zn vacancy, and thereby stabilizes the zinc vacancy. Room temperature ferromagnetism with p type conduction was observed in pulsed laser deposited ZnO:Li films with certain doping concentration and oxygen partial pressure.
