Abstract
OBJECTIVE To understand the current status of chronic filariasis patients in Huai'an City, so as to provide insights into the future care of chronic filariasis patients. METHODS According to the data pertaining to the historically registered chronic filariasis patients in Huai 'an City, each case was followed up and the baseline data of chronic filariasis patients were captured using questionnaire survey. The demographic and clinical features of the patients, and the distribution and coverage of the care sites were analyzed. RESULTS There were still 616 chronic filariasis patients in Huai'an City, including 229 men (37.2%) and 387 women (62.8%), and 93.2% were aged 60 years and older. The chronic filariasis patients were found across the 8 counties (districts) across the city, and the cases were predominantly detected in Lianshui (40.3%), Huaiyin (30.8%) and Yuyi (8.0%). There were 49.0% of the patients with lymphedema or elephantiasis alone, 10.2% with chyluria alone, 1.0% with hydrocele of tunica vaginalis alone, 2.4% with lymphatic inflammation or lymphadenitis alone, and 37.3% with two or more types of symptoms, respectively, and all cases with lymphedema or elephantiasis alone had the sites of edema in the lower limbs, with over 90% at stages I to III. Currently, there are 81 care sites in the city covering 567 patients. The mean number of care activities was 3.2 times in 2018, and the mean cumulative duration of caring activities was 18.4 years in the care sites. CONCLUSIONS Although the number of chronic filariasis patients has remarkably decreased, the number remains high in Jiangsu Province, and the cases are characterized by high age and long course of disease. Further caring activities are required to improve the quality of life in chronic filariasis patients.

Abstract
AIM To undertake a systematic review and meta-analysis of the diagnostic performance of CT for differentiating peritoneal tuberculosis (PTB) from peritoneal carcinomatosis (PC). MATERIAL AND METHODS PubMed, Embase, the Web of Science, and the Cochrane Library were searched for papers published before 23 July 2019. The methodological quality of the studies was analysed. Overlapping descriptors used in different studies to denote the same image finding were subsumed under a single CT feature. Sensitivity, specificity, and positive and negative likelihood ratios were pooled. A summary receiver operating characteristic curve (sROC) was constructed and the area under the curve (AUC) of the included studies was calculated when possible. RESULTS Six studies were included and 17 CT features were analysed. The pooled sensitivity and specificity of smooth peritoneal thickening were 59% (95% CI: 52-66%) and 84% (95% CI: 79-88%), respectively. The AUC of smooth peritoneal thickening was 0.83. Omentum line/rim, lymph node necrosis or calcification, and mesenteric macro nodules had a pooled specificity ranging from 95% to 100% and a pooled sensitivity ranging from 12% to 67%. The other 12 signs had a pooled sensitivity ranging from 21% to 79% and a pooled specificity ranging from 19% to 81%. Omentum involvement (cake-like pattern) showed a threshold-effect, so only the AUC (=0.70) was calculated. CONCLUSIONS Smooth peritoneal thickening shows fairly good diagnostic accuracy, while omentum rim/line, lymph nodes necrosis or calcification, mesenteric macro nodules have good specificity but limited sensitivity. The informative features summarised in this study may aid clinical practice and future studies.

Abstract
OBJECTIVE To evaluate the effect of oltipraz (OPZ) on isoproterenol-induced heart failure (HF) and heart function. We also explore the underlying molecular mechanism of OPZ. MATERIALS AND METHODS The rats were randomly divided into four groups, including normal control group, isoproterenol (ISO) group, ISO +100 mg/kg OPZ group, and OPZ group. Hemodynamic parameters, such as left-ventricular systolic pressure, were statistically analyzed. Besides, plasma levels of brain natriuretic peptide (BNP), pro-inflammatory cytokines and antioxidant markers were assessed by using enzyme-linked immunosorbent assay (ELISA). Moreover, histopathological examination was applied to assess the degree of cardiac interstitial fibrosis. RESULTS OPZ could statistically improve the hemodynamic parameters of the heart function, and could also obviously attenuate cardiac interstitial fibrosis in ISO-induced HF rats when compared with the ISO group. Besides, plasma level of BNP in ISO +100 mg/kg OPZ group dramatically decreased in comparison with that of ISO group. Moreover, compared with ISO group, OPZ treatment significantly reduced the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Moreover, OPZ treatment remarkably increased the levels of antioxidant markers such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) in ISO-induced HF rats. CONCLUSIONS OPZ administration may provide experimental evidence for the possible effect of OPZ on isoproterenol-induced heart failure in rats. Moreover, OPZ administration may have potential utility for the treatment of heart failure.

Abstract
Mitochondrial antiviral signaling protein (MAVS), a crucial adaptor protein localized on mitochondria, plays vital roles in various biological processes. Autophagy and apoptosis are two independent and closely linked cell death pathways. But whether MAVS could induce apoptosis and autophagy in rhabdomyosarcoma cells (RD cells) and what is the relationship between autophagy and apoptosis still remains elusive. Here, we reveal that overexpression of MAVS could trigger both apoptosis and autophagy in RD cells. Interestingly, MAVS-induced apoptosis was dependent on the activation of the c-Jun N-terminal kinase (JNK) signaling pathway and inhibition of the extracellular signal-regulated kinase (ERK) signaling pathway. Also, it was found that inhibition of autophagy by 3-methyladenine (3-MA) enhanced MAVS-induced apoptosis resulting in increased cleavage of caspase-3 and poly (ADP-ribose) polymerase (PARP). Meanwhile, autophagy induction by rapamycin resulted in decreased MAVS-induced apoptosis. In addition, we found that MAVS expression was inhibited upon Coxsackievirus A16 (CA16) infection and overexpression of MAVS could inhibit CA16 replication. Collectively, our study provides novel insights into the link between apoptosis and autophagy induced by MAVS overexpression in RD cells and gains a greater understanding of MAVS-induced antiviral functions, which provide new targets for CA16 treatment. Keywords: CA16; MAVS; apoptosis; autophagy.

Abstract
OBJECTIVE To investigate the clinical functions and the detailed mechanism of long noncoding RNA (lncRNA) JPX in human ovarian cancer cell lines. PATIENTS AND METHODS The expression of JPX in ovarian cancer tissues and cell lines was detected by Real-time polymerase chain reaction (RT-PCR). The correlation between JPX expression and prognosis was analyzed by follow-up data. The OVCAR-3 cell proliferation, invasion and migration were measured by methyl thiazolyl tetrazolium (MTT) assay, cloning formation assay and scratch assay. The cell apoptosis was detected by Bcl-2, Bax, and Caspase-3 activity. PI3K/mTOR inhibitor treatment and Western blot proved that JPX functions associated with PI3K/Akt/mTOR signaling and test the protein levels of p-PI3K, p-Akt, p-mTOR. RESULTS RT-PCR results showed that the expression of JPX was upregulated in ovarian cancer tissues and ovarian cancer cell lines (p < 0.05), and it was significantly increased in large tumor tissues and metastatic lymph nodes (p < 0.05). The survival rate of high JPX expression patients was much lower than low JPX expression patients (p < 0.05), indicating that high expression of JPX predicted poor prognosis in patients with ovarian cancer. MTT assay, colony formation and scratch assay showed the repression of JPX and resulted with significantly decreased in cell proliferation, invasion and migration of OVCAR-3 cells compared with the control (p < 0.05). PI3K/mTOR inhibitor treatment showed overexpression of JPX could activate the PI3K/Akt/mTOR signaling pathway. Western blot assay showed that the expressions of p-PI3K, p-Akt, p-mTOR were significantly increased after overexpression of JPX (p < 0.05), and after the inhibition of PI3K/Akt/mTOR signaling pathway and overexpression of JPX, the tumor cell proliferation, invasion and migration were significantly repressed, compared with the control (p < 0.05). CONCLUSIONS JPX could predict the poor prognosis in patients with ovarian cancer, which could promote the tumor cell proliferation, invasion and migration in human ovarian cancer cell lines and inhibited the cell apoptosis through activating PI3K/Akt/mTOR signaling pathway.

Abstract
Objective: To compare the efficacy and safety profiles of tiotropium/olodaterol with the mono-components in Chinese and total study population from TONADO trial. Methods: In the replicate, double-blind, parallel-group, active-controlled, randomized, 52-week, Phase Ⅲ TONADO studies (TONADO 1+2), patients received tiotropium/olodaterol, tiotropium, or olodaterol via the Respimat(®) Inhaler (Boehringer Ingelheim, Germany). Primary end points were forced expiratory volume in 1 second (FEV(1)) area under the curve from 0 to 3 hours (AUC(0-3h)) response and trough FEV(1) response, and St George's respiratory questionnaire (SGRQ) total score at 24 weeks. Adverse events were also collected. This subgroup analysis only focused on the efficacy and safety of the drug at the approved dose in China. Results: 548 Chinese patients were randomized, aged 41 to 82 years [mean age, (63±8) years] and most were male (526, 96%), 111 received tiotropium/olodaterol 5/5 μg, and 127 received tiotropium 5 μg and 95 received olodaterol 5 μg. The baseline characteristics of these groups were similar. After 24 weeks, treatment with tiotropium/olodaterol 5/5 μg, tiotropium 5 μg and olodaterol 5 μg resulted in an adjusted mean FEV(1) AUC(0-3h) response of 0.240, 0.157 and 0.079 L, and trough FEV(1) response of 0.117, 0.068 and-0.001 L, respectively. Tiotropium/olodaterol 5/5 μg significantly improved SGRQ scores in Chinese patients compared with olodaterol 5 μg (32.729 and 37.202, respectively). Generally, the safety profile of tiotropium/olodaterol was comparable with mono-components in 52 weeks. Conclusion: Compared with tiotropium or olodaterol, tiotropium/olodaterol in Chinese patients provided significant improvement in lung function and quality of life, and the safety profiles were similar.

Abstract
Objective: To validate whether the prognostic stage groups by the 8th edition of the American Joint Committee on Cancer (AJCC) staging system provides improved prognostic accuracy in T1-2N1M0 postmastectomy breast cancer patients compared to 7th edition. Methods: a total of 1 823 female patients with T1-2N1M0 breast cancer who underwent mastectomy and axillary lymph node dissection without neoadjuvant chemotherapy were analyzed and restaged according to 8th edition. Univariate analysis of prognostic factors was evaluated by using log-rank test. Multivariate analysis was estimated by using the Cox proportional hazards model. The prognostic accuracy of the two staging systems was compared using receiver operating characteristic (ROC) analyses and the concordance index (C-index). Results: 5-year locoregional recurrence rate (LRR) for the whole group was 6.0%, 5-year distant metastasis (DM) rate was 11.5%, 5-year disease-free survival (DFS) was 85.0%, and 5-year overall survival (OS) was 93.1%. Cox analysis showed that 7th edition of the AJCC staging system and progesterone receptor status were independent risk factors for LRR, DM, DFS and OS (P<0.05). Compared with stage by 7th edition, 1 278(70.1%) were assigned to a different prognostic stage group: 1 088 (85.1%) to a lower stage and 190 (14.9%) to a higher stage. LRR, DM, DFS and OS were significantly different between prognostic stage ⅠA, ⅠB, ⅡA, ⅡB and ⅢA according to 8th edition of the AJCC staging system(P<0.001). Prognostic stage had significantly higher C-indexes and provided better estimation of prognosis compared to stage by 7th edition of the AJCC staging system (P<0.001). Conclusion: The prognostic stage groups of 8th edition AJCC staging system has superior prognostic accuracy compared to 7th edition in T1-2N1M0 breast cancer, and has better clinical therapeutic guidance value.

Abstract
Humanacellular dermal matrix (HADM) is widely used in the field of burn wound repair and tissue engineering plastic surgery. HADM is manufactored by physical and chemical decellular process to remove the antigenic components that might cause immune rejection in dermis.The extracellular matrix of three-dimensional cell scaffold structure with collagen fibers had been used for wound repair and tissue regeneration, while HADM characterized with low absorption rate after implantation and strong ability to induce angiogenesis in host tissue. Studies reported that after the HADM was implanted into the patient, the host cells, such as fibroblasts and myofibroblasts, as well as lymphocytes, macrophages, granulocytes and mast cells, rapidly infiltrated the graft. The connective tissue and neovascularization were then formed within the HADM three-dimensional cell scaffold, the lymphatic system also appears after vascular reconstruction. Traditional urethral reconstruction using autologous skin flaps has some defects, such as complexity of the technology, risk of necrosis of the skin flaps after transplantation, and failure to achieve functional repair of the urethral epithelium. It has been reported that using HADM to reconstruct the urethra in patients with urethral stricture, hypospadias and bladder-vaginal fistula, showed promising results. Others have reported the experience of using HADM to repair and reconstruct congenital classic bladder exstrophy. HADM has also been used for tissue repair in patients with penile skin defect caused by Fonier's gangrene and hidradenitis suppurativa, and implanted under Bucks' fascia to enlarge the penis. The report of HADM implantation for treating premature ejaculation also deserves attention. Researchers found that HADM implantation can form a tissue barrier between the skin and corpus cavernosum, which can effectively reduce penile sensitivity and treat premature ejaculation. The safety and effectiveness of HADM implantation in the treatment of premature ejaculation need to be further standardized by data from multi-center, large-sample clinical studies. In summary, HADM is the extracellular matrix and three-dimensional cell scaffold of human dermis. As a new type of tissue repair material, new blood vessels are formed actively after implantation, which shows good histocompatibility. HADM has shown increasingly broad application prospects in treatment of genitourinary diseases including penis, urethra and bladder diseases. HADM has also been used in the treatment of premature ejaculation in recent clinical studies, and its long-term safety and efficacy need to be further investigated.

Abstract
Objective: To investigate the effect of skin soft tissue expansion on repair of large area of scars on extremities. Methods: Twenty-five patients with large area of scars on extremities were admitted to our department from June 2007 to October 2014. There were 14 males and 11 females, aged 4 to 36 years. Operations were performed under local infiltration anesthesia or general anesthesia. In the first stage, 1 to 5 cylindrical expanders with capacities of 250 to 600 mL were placed at left or right sides or at upper or lower parts of the scars. In the second stage, scars of 21 patients were repaired with expanded transverse propulsive and lateral flaps, and scars of 4 patients were repaired with expanded perforator flaps whose pedicles were perforators of brachial artery, superior ulnar collateral artery, or posterior interosseous artery according to areas and shapes of the scars. The secondary wound areas ranged from 13 cm×7 cm to 34 cm×18 cm after dissolution or excision of scars. The areas of flaps ranged from 13 cm×7 cm to 20 cm×12 cm. The donor sites were sutured directly. The flaps after operation and follow-up of patients were observed and recorded. Results: All expanded flaps survived after operation. And the superficial distal part of flap whose pedicle was perforator of posterior interosseous artery in one patient was with necrosis, and other flaps survived well. During follow-up of 3 to 15 months after operation of the second stage, color and texture of flaps were similar to surrounding skin, while extremities of donor sites were thinner and auxiliary incisional scars formed after expansion. Conclusions: Expanded flap is a good way to repair large area of scar on extremities. Bilateral skin of scar is the first choice of donor site of expanded flap. If there isn't enough skin for expanding on bilateral sides, expanded perforator flap designed at upper or lower part of the scar is another choice to repair the scar.

Abstract
BACKGROUND Clinical evidence suggests that curcuminoids, as a natural polyphenol, can provide support for cardioprotection and glucose metabolism. This meta-analysis assessed the efficacy and safety of curcumin with respect to improving glucose metabolism in patients with cardiovascular risk factors. METHODS Four databases (PubMed, Cochrane Library, Web of Science and Embase) were searched up to June 2018. The inclusion criteria included (i) randomised controlled trials (RCT) and (ii) subjects with risk factors for cardiovascular disease supplemented with curcumin and curcuminoids. A random-effects model and a standardised mean difference with a 95% confidence interval were used to perform quantitative data synthesis. Sensitivity and subgroup analyses were conducted to assess the effects. RESULTS Fourteen eligible RCT with 1277 subjects were included. In the overall analyses, curcumin led to significant decreases in fasting blood glucose (FBG), glycated haemoglobin (HbA1c) and homeostatic model assessment of insulin resistance (HOMA-IR). The subgroup analyses suggested that curcumin or combined curcuminoids were more effective at reducing FBG and HbA1c in type 2 diabetes patients than in individuals with metabolic syndrome. Supplementation with curcuminoids at doses ≥300 mg day-1 showed significant decreases in FBG, HbA1c and HOMA-IR. The effects of supplementation on FBG, HbA1c and HOMA-IR were more significant over long periods (≥12 weeks) than short periods. Curcumin and curcuminoids were well tolerated, with no serious adverse events. CONCLUSIONS Curcumin or combined curcuminoids could exert cardioprotective effects in patients at risk for cardiovascular disease by improving glucose metabolism. However, further high-quality studies and larger sample sizes are required to confirm these results.

Abstract
Progress in neurodevelopmental brain research has been achieved through the use of animal models. Such models not only help understanding biological changes that govern brain development, maturation and aging, but are also essential for identifying possible mechanisms of neurodevelopmental and age-related chronic disorders, and to evaluate possible interventions with potential relevance to human disease. Genetic relationship of rhesus monkeys to humans makes those animals a great candidate for such models. With the typical lifespan of 25 years, they undergo cognitive maturation and aging that is similar to this observed in humans. Quantitative structural neuroimaging has been proposed as one of the candidate in vivo biomarkers for tracking white matter brain maturation and aging. While lifespan trajectories of white matter changes have been mapped in humans, such knowledge is not available for nonhuman primates. Here, we analyze and model lifespan trajectories of white matter microstructure using in vivo diffusion imaging in a sample of 44 rhesus monkeys. We report quantitative parameters (including slopes and peaks) of lifespan trajectories for 8 individual white matter tracts. We show different trajectories for cellular and extracellular microstructural imaging components that are associated with white matter maturation and aging, and discuss similarities and differences between those in humans and rhesus monkeys, the importance of our findings, and future directions for the field. Significance Statement: Quantitative structural neuroimaging has been proposed as one of the candidate in vivo biomarkers for tracking brain maturation and aging. While lifespan trajectories of structural white matter changes have been mapped in humans, such knowledge is not available for rhesus monkeys. We present here results of the analysis and modeling of the lifespan trajectories of white matter microstructure using in vivo diffusion imaging in a sample of 44 rhesus monkeys (age 4-27). We report and anatomically map lifespan changes related to cellular and extracellular microstructural components that are associated with white matter maturation and aging.

Abstract
Objective: To investigate the expression of microRNA-133b (miR-133b) in esophageal squamous cell carcinoma (ESCC), and explore its effect and the underlying molecular mechanisms on cell proliferation and invasion. Methods: Real-time quantitative PCR (qPCR) was used to examine miR-133b expression in 63 ESCC tissues and paired adjacent non-cancerous tissues, several ESCC cells (Eca109, EC9706, EC1, TE1, KYSE70) and normal esophageal epithelial cell Het-1A. MiR-133b mimic, inhibitor and negative control (NC) were transfected into TE1 cells. The effect of miR-133b on cell proliferation and invasion were determined by CCK-8 and Transwell assays, respectively. Subsequently, the target gene of miR-133b was predicted by online tools TargetScan and miRDB, which was verified by dual luciferase reporter assays. Finally, Western blot was utilized to detect the effects of miR-133b overexpression on expression of target gene TAGLN2 as well as EMT-related proteins E-cadherin, N-cadherin, Snail, Slug and Vimentin. Results: Relative levels of miR-133b in ESCC tissues (0.295±0.040) were significantly lower than those in adjacent non-cancerous tissues (1.002±0.011, P<0.001). The expression of miR-133b was tightly associated with clinical staging, lymph node metastasis and prognosis. Moreover, relative levels of miR-133b in ESCC cells Eca109, EC9706, EC1, TE1 and KYSE70 (0.679±0.031, 0.391±0.008, 0.236±0.016, 0.031±0.005 and 0.099±0.020) were evidently lower than that in normal esophageal epithelial cell Het-1A (1.005±0.016, all P<0.001). In TE1 cells, miR-133b mimic significantly increased the level of miR-133b to 6.199±0.627, and suppressed cell proliferation and invasion, whereas miR-133b inhibitor obviously decreased its expression to 0.182±0.023, and promoted cell proliferation and invasion. Most notably, the relative luciferase activities of miR-133b-mimic group (0.320±0.018) in TE1 cells transfected with TAGLN-3'UTR-WT were markedly lower than that in NC group (1.010±0.036, P<0.001), whereas those in TAGLN-3'UTR-MUT transfection cells were 1.019±0.056 and 1.008±0.021, respectively, showing no significantly statistical difference (P>0.05). Furthermore, miR-133b overexpression markedly downregulated TAGLN2, N-cadherin, Snail, Slug and Vimentin levels, and increased E-cadherin expression. Conclusion: MiR-133b plays an important role in the proliferation and invasion of ESCC cells by regulating TAGLN2 expression, and it may be a potential therapeutic target for ESCC patients.

Abstract
AIMS To evaluate the effect of pregabalin on radiotherapy-induced trismus in patients with nasopharyngeal carcinoma, a hospital-based, clinical retrospective cohort study was conducted. MATERIALS AND METHODS Data were collected on patients diagnosed with radiotherapy-induced trismus from March 2014 and March 2016 in the department of neurology in our hospital. Patients in the treatment group were administrated pregabalin for 8 weeks combined with rehabilitation, while the control group only received rehabilitation. The clinical therapeutic effects were observed and evaluated by mandibular motion, severity of trismus measured by late effects of normal tissues/subjective and objective medical analysis (LENT/SOMA) scales, and quality of life (QOL) assessed using the World Health Organization QOL instrument (WHOQOL-BREF) at baseline, week 4 and week 8 during treatment in these two groups, respectively. RESULTS In the treatment group, the number of patients with improvement on maximal vertical dimension (MVD) was significantly more than controls at week 4 and week 8 (P=0.013, P=0.004, respectively). Moreover, at week 4 and week 8, the severity of trismus was both significantly improved on LENT/SOMA grade in treatment group (P=0.047, P=0.032, respectively). And at week 8, the physical health and the whole life domain of the WHOQOL-BREF score were significantly increased (P=0.037, P=0.034, respectively). In the treatment group, 11 patients (36.7%) presented dizziness, and 7 patients (23.3%) presented somnolence. CONCLUSIONS Administration of pregabalin, in adjunct to rehabilitation, might provide a better outcome in patients with radiotherapy-induced trismus.

Abstract
Amphetamines are chemical synthetic drugs that are becoming increasingly popular in China. As a common sample in the inspection of poisons, hair has the advantages of easy storage, good stability, and long detection time compared with traditional human body fluid samples (blood, urine), thus possesses an unique application value in the field of forensic toxicology analysis. By now, methods for detecting amphetamines in human hair have been widely used, and validity of the results has been recognized and adopted by the court. This paper reviews domestic and foreign research progress of the detection of amphetamines in hair samples, including the pretreatment and analytic methods.

Abstract
Currently available drug delivery systems for oral diseases suffer from short retention time and poor local concentrations at the target site. A biodegradable stimulus-responsive hydrogel was synthesized in the present study to evaluate its application as an environmentally sensitive carrier for on-demand intraoral drug delivery. The hydrogel was synthesized from diacrylate-containing polyethylene glycol-based scaffolds and a cysteine-terminated peptide crosslinker (CGPQG↓IWGQC) via a Michael-type addition reaction. Because CGPQG↓IWGQC can be cleaved by matrix metalloproteinase 8 (MMP-8), minocycline hydrochloride, bovine serum albumin, or an antibacterial peptide (KSL) was incorporated into the scaffolds to evaluate the MMP-8-responsive release behavior of the on-demand drug delivery system. Hydrogel characterization and gelation kinetics were examined with gel time, Fourier-transform infrared spectroscopy, scanning electron microscopy, and measurements of rheologic parameters. Degradation behavior and MMP-8-responsive drug release were performed by high-performance liquid chromatography and protein-specific assay. Biocompatibility evaluation indicated that the hydrogels were noncytotoxic. Antibacterial testing demonstrated that the released drugs were able to maintain bioactivity. Taken together, these results suggest that the MMP-8-sensitive hydrogel is a promising candidate for on-demand intraoral localized drug delivery. Because MMP-8 is one of the most important biomarkers for periodontitis, the MMP-8-responsive hydrogel has potential to be used for in situ adaptive degradation in response to chronic periodontitis and peri-implantitis. This notion has to be tested in animal models of periodontal disease.

Abstract
Objective: To investigate the clinical and prognostic differences between primary nasopharyngeal natural killer (NK)/T-cell lymphoma (NP NKTCL) and extranodal NK/T-cell lymphoma of the nasal cavity with nasopharynx extension (N-NP NKTCL). Methods: A total of 89 patients with NP NKTCL and 113 patients with N-NP NKTCL from January 2000 to June 2015 were retrospectively analyzed. Clinical and pathological features, treatment responses and prognosis were compared between the two groups. Results: NP NKTCL patients showed similar clinicopathological features with those with N-NP NKTCL, except that the former had a relative low proportion of elevated lactate dehydrogenase (LDH) levels (28.1% vs. 41.6%; P=0.001). Both of two groups presented with high proportion of cervical lymph node involvement (55.1% and 42.5%; P=0.076). The 5-year overall survival (OS) rates in these two groups were 63.2% and 54.6%, respectively, whereas 5-year progress-free survival (PFS) rates were 50.7% and 45.6%, respectively. For the patients with stage Ⅰ and Ⅱ, the 5-year OS and PFS rates in these two groups were 68.8% and 55.7% as well as 55.6% and 47.2%, respectively. These were no statistically significant differences between two groups (all P>0.05). The complete response (CR) rate after initial chemotherapy in NP NKTCL group was 43.8%, which was significant higher than that of 19.6% in N-NP NKTCL group (P=0.006). Additionally, the CR rate after primary radiotherapy was 63.4% and 62.7%, respectively (P=0.629). The NP NKTCL patients with stage Ⅰ and Ⅱ who accepted radiotherapy with or without chemotherapy had similar survival times with chemotherapy alone, showing the 5-year OS rates of 70.5% and 33.3% (P=0.238), as well as the 5-year PFS rates of 56.7% and 33.3%, respectively (P=0.431). Similar results were found in N-NP NKTCL group, the 5-year OS rates for patients with radiotherapy with or without chemotherapy and chemotherapy alone were 57.4% and 33.3% (P=0.246), while the 5-year PFS rates were 49.3% and 16.7% (P=0.177), respectively. Besides, the relapse pattern of NP NKTCL and N-NP NKTCL groups was also similar, mainly involving the distant extra-nodal organs followed by lymph nodes. Conclusion: The patients with N-NP NKTCL and NP NKTCL showed similar clinical and prognostic features, however, the initial response to chemotherapy was different.

Abstract
After three decades of intensive research attention, the emergence of superconductivity in cuprates remains an unsolved puzzle. One major challenge has been to arrive at a satisfactory understanding of the unusual metallic "normal state" from which the superconducting state emerges upon cooling. A second challenge has been to achieve a unified understanding of hole- and electron-doped compounds. Here, we report detailed magnetoresistance measurements for the archetypal electron-doped cuprate Nd2-x Ce x CuO4+δ that, in combination with previous data, provide crucial links between the normal and superconducting states and between the electron- and hole-doped parts of the phase diagram. The characteristics of the normal state (magnetoresistance, quantum oscillations, and Hall coefficient) and those of the superconducting state (superfluid density and upper critical field) consistently indicate two-band (electron and hole) features and point to hole pocket-driven superconductivity in these nominally electron-doped materials. We show that the approximate Uemura scaling between the superconducting transition temperature and the superfluid density found for hole-doped cuprates also holds for the small hole component of the superfluid density in electron-doped cuprates.

Abstract
Distributed ditches and ponds in agricultural landscapes can retain agricultural pollutants (such as nutrients and pesticides) like wetlands while facilitating crop field drainage. Their complex hydraulic conditions affect pollutant transport and degradation processes, but the existing lump-sum method for estimating pollutant removal treats the total area simply as one unit without considering their specific hydraulic conditions (HCs). In this paper we proposed an analytical method for evaluating pollutant removal efficiencies of distributed ditches and ponds by considering their different HCs explicitly. A realization factor (RF) was used to compare pollutant removal rates with and without considering specific HCs. Application of the method was demonstrated with a case study based on field investigations in an intensively farmed area in southeastern China. The total area of ditches and ponds accounts for 15% of drained crop fields; and the calculated RFs were 0.70-0.84% for various removal rate constants. The difference was mainly caused by the uneven distribution of ditches and ponds along different drainage paths. For pollutants with small values of removal rate constants, the calculated concentration reductions along different flow paths were proportional to their wetland sizes, making the pollutant removal as area limited. For pollutants with larger values of removal rate constant, however, the calculated pollutant removal became concentration limited when the wetland to farmland area ratio was high. Large ponds and ditches were major contributors (85-94%) of pollutant removal in the whole system, while the field ditches contributed to less than 10% of the total removal due to their small dimension and shallow water depth. The distributed nature of ditches and ponds poses some inherent limitations to their water quality functions due to variable hydraulic conditions; understanding such underlying constraints may help guide proper evaluation and conservation of the existing ditches and ponds in agricultural landscapes.

Abstract
Objective: To compare and analyze the epidemiological characteristics of hospitalized elderly, young and middle-aged patients with severe burn in recent years, so as to provide reference for the prevention and treatment of elderly patients with severe burn. Methods: Relying on the entry system of epidemiological case data and biological sample of severe burn from multicenter in clinic, medical records of patients with severe burn, aged above 18, hospitalized in 8 burn wards from January 2012 to December 2015 were collected. Six hundred and fifteen patients who were more than 18 years old and less than or equal to 65 years old were included in young and middle-aged group (YM). Eighty-two patients aged more than 65 years old were included in elderly group (E). Data of age, gender, residence, education level, cause of injury, location of injury, season of injury, total burn area, occurrence and area of full-thickness burn injury, wound site, inhalation injury incidence and severity, post burn admission time, proportion of delayed resuscitation, proportion of escharectomy or tangential excision and skin grafting, preinjury systemic disease, system complication during hospitalization, length of hospital stay, outcome of treatment, and reason of abandoning treatment of patients were analyzed. Data were processed with chi-square test and Mann-Whitney U test. The odds ratios of preinjury systemic disease, system complication during hospitalization, and adverse outcome of patients in group YM were compared with those in group E. Results: (1) The majority of patients in the two groups were male, but the proportion of male patients in group YM was higher. There was statistically significant difference in gender distribution of patients between the two groups (χ(2)=18.727, P<0.001). The majority of patients in the two groups were from rural areas, but the proportion of rural patients in group E was higher. There was statistically significant difference in residence distribution of patients between the two groups (χ(2)=9.306, P=0.002). Patients in group YM mainly had secondary education, while patients in group E mainly had primary education. There was statistically significant difference in distribution of education level of patients between the two groups (χ(2)=146.797, P<0.001). (2) The most common causes of injury of patients in the two groups were both flame, but the proportion of patients with flame burn injury in group E was higher. There was statistically significant difference in distribution of cause of injury of patients between the two groups (χ(2)=25.063, P<0.001). The main locations of injury of patients in groups YM and E were respectively public place and private residence. There was statistically significant difference in location distribution of injury of patients between the two groups (χ(2)=46.313, P<0.001). The main seasons of injury of patients in groups YM and E were respectively summer and winter. There was statistically significant difference in season distribution of patients between the two groups (χ(2)=23.143, P<0.001). There was statistically significant difference in distribution of total burn area of patients between the two groups (χ(2)=25.799, P=0.002). The occurrences of full-thickness burn injury of patients in the two groups were similar (χ(2)=2.685, P=0.101), while there was statistically significant difference in area of full-thickness burn injury of patients between the two groups (χ(2)=26.702, P=0.002). There was no statistically significant difference in distribution of wound site of patients between the two groups (χ(2)=3.954, P=0.785). There were no statistically significant differences in incidence and severity distribution of inhalation injury of patients between the two groups (with χ(2) values respectively 0.425 and 0.672, P values above 0.05). (3) There was statistically significant difference in distribution of admission time of patients between the two groups (χ(2)=6.632, P=0.036), but there was no statistically significant difference in proportion of delayed resuscitation of patients between the two groups (χ(2)=1.261, P=0.261). The proportion of escharectomy or tangential excision and skin grafting of patients in group YM was 72.0% (443/615), which was significantly higher than 35.4% (29/82) of group E (χ(2)=44.498, P<0.001). The incidence of preinjury systemic disease of patients in group YM was 13.2% (81/615), which was significantly lower than 61.0% (50/82) of group E (χ(2)=108.337, P<0.001). The risk of preinjury systemic disease of patients in group E was 10.30 times of that of patients in group YM [with 95% confidence interval (CI) of 6.24-17.01, P<0.001]. During hospitalization, 59.8% (49/82) of patients in group E suffered from system complications, which was significantly higher than 36.6% (225/615) of group YM (χ(2)=16.282, P<0.001). The risk of system complication of patients in group E was 2.57 times of patients in group YM (with 95% CI of 1.61-4.12, P<0.001). The length of hospital stay of patients in group E was significantly shorter than that of group YM (U=36 735, P<0.001). There was statistically significant difference in treatment outcome of patients between the two groups (χ(2)=106.251, P<0.001). The risk of adverse outcome of patients in group E was 7.52 times of group YM (with 95% CI of 4.40-12.88, χ(2)=67.709, P<0.001). The proportion of abandoning treatment of patients in group E was significantly higher than that of group YM (χ(2)=150.670, P<0.001). The risk of abandoning treatment of patients in group E was 15.86 times of that of group YM (with 95% CI of 9.36-26.88, P<0.001). There was no statistically significant difference in distribution of reason of abandoning treatment of patients between the two groups (χ(2)=4.178, P=0.243). Conclusions: There were significant differences in the epidemiological characteristics of patients in groups E and YM. In elderly burn patients, the proportion of rural population was higher and the education level was lower. Flame burn was common and burns mostly occurred in private residences and in winter. The total burn area was slightly lower but the area of full-thickness burn injury was larger. The length of hospital stay was shorter and the proportion of surgical treatment was lower. The incidences of preinjury systemic disease and system complication during hospitalization were higher, and therefore the risks of adverse outcome and abandoning treatment were higher.

Abstract
Molecular emission can be used for isotopic analysis in laser-induced breakdown spectroscopy (LIBS) due to its large isotopic shift. However, spectral weakness and interference have become the main flaws in molecular isotopic analysis, causing deterioration of quantitative accuracy and sensitivity. Here, to overcome these problems, laser-induced radical fluorescence (LIRF) was applied to enhance the molecular spectra and eliminate the spectral interference. The root mean square errors of cross validation (RMSECVs) of boron and carbon isotopes (11BO, 10BO, 12CN, and 13CN) improved to 2.632, 5.721, 5.990, and 1.543 at.%, as compared with 16.96, 35.79, 57.10, and 13.89 at.%, respectively, obtained in the case without LIRF. The limits of detection (LoDs) of 11BO, 10BO, 12CN, and 13CN were 0.9858, 0.8470, 1.606, and 1.193 at.%, respectively. This work demonstrates the feasibility of LIBS-LIRF to achieve isotopic determination with high accuracy and sensitivity.

Detection of novel mutations associated with independent resistance and cross-resistance to isoniazid and prothionamide in Mycobacterium tuberculosis clinical isolates. Clin Microbiol Infect 2018; 25:1041.e1-1041.e7. [PMID: 30583053 DOI: 10.1016/j.cmi.2018.12.008] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 11/20/2018] [Accepted: 12/08/2018] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Prothionamide, a structural analogue of isoniazid, is used mainly for treating multidrug-resistant tuberculosis (MDR-TB). Both drugs have a common target InhA, so prothionamide can be ineffective against isoniazid-resistant (INHR) Mycobacterium tuberculosis. We aimed to investigate the prevalence of mutations in katG, ethA, ndh, ethR, mshA, inhA and/or its promoter associated with independent resistance and cross-resistance to INHR and/or prothionamide-resistant (PTOR) M. tuberculosis isolates. METHODS We sequenced the above genes in 206 M. tuberculosis isolates with susceptibility testing against ten drugs. RESULTS Of the 173 INHR PTOR isolates, 170 (98.3%) harboured mutations in katG, 111 (64.2%) in ethA, 58 (33.5%) in inhA or its promoter, 5 (2.9%) in ndh, 3 (1.7 %) in ethR and 2 (1.2%) in mshA. Among the 18 INHR PTOS isolates, mutations in katG were found in all of them; one had a mutation in the inhA promoter and another in ndh. Of the five INHS PTOR isolates, four showed mutations in ethA and two in the inhA promoter. Notably, 55 novel non-synonymous mutations were found in them and 20.2% of the PTORM. tuberculosis isolates harboured no known mutations. CONCLUSIONS This is the first report to investigate cross-resistance between INHR and/or PTOR isolates. Among INHR (94.4% MDR-TB) M. tuberculosis isolates, the high diversity of mutations for independent resistance and cross-resistance with prothionamide highlight the importance of both phenotypic susceptibility and genotypic diagnosis when using it to treat patients with INHR-TB. The high proportion (one-fifth) of PTORM. tuberculosis isolates showed no known mutation related to PTOR genes, so uncovered resistance mechanism(s) of prothionamide exist.

Abstract
BACKGROUND Effective diagnostic methods for detecting latent tuberculosis infection (LTBI) are important for its eradication. A number of studies have evaluated the use of interferon-γ-induced protein 10 (IP-10), which is elevated after tuberculosis infection, as a biomarker for LTBI, but conclusive results regarding its effectiveness have not been reported. OBJECTIVES Our objective was to assess the diagnostic value of IP-10 for LTBI. DATA SOURCES We searched the PubMed, Embase, the Cochrane Library and Web of Science databases to find eligible studies. STUDY ELIGIBILITY CRITERIA We included cohort, case-control and cross-sectional studies that evaluated IP-10 in LTBI participants in comparison with tuberculin skin tests (TST) and interferon-γ release assays (IGRA). PARTICIPANTS Individuals with LTBI and uninfected participants. INTERVENTIONS IP-10 (index test) compared with TST and IGRA (reference standard) for diagnosing LTBI. METHODS PubMed, Embase, the Cochrane Library, and Web of Science databases were searched up to June 2018. A hierarchical summary receiver operating characteristic (HSROC) model was used to evaluate the pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and HSROC curve for the diagnostic efficiency of IP-10. RESULTS Twelve studies including 1023 participants and 1122 samples were included. The overall pooled sensitivity was 0.85 (95% CI 0.80-0.88), specificity was 0.89 (95% CI 0.84-0.92), PLR was 7.55 (95% CI 5.20-10.97), NLR was 0.17 (95% CI 0.13-0.22) and DOR was 44.23 (95% CI 28.86-67.79), indicating a high accuracy for diagnosing LTBI. Based on a meta-regression analysis, high-burden countries, study design, IP-10 method, reference standard and the IP-10 cut-off could not explain the heterogeneity (p >0.05). CONCLUSIONS Our results suggested that IP-10 is a promising biomarker for the diagnosis of LTBI.

Abstract
Objective: To explore the expression of microRNA(miR)-147b in esophageal squamous cell carcinoma (ESCC) and its regulatory roles in cell proliferation, cell cycle and invasion as well as its molecular mechanisms. Methods: Real-time quantitative PCR (qPCR) was used to investigate the expression of miR-147b in ESCC tissues and cells. Negative control (NC) and miR-147b inhibitor were transfected into ESCC EC1 and EC9706 cells, which were divided into two groups: NC group and miR-147b inhibitor group, and qPCR was employed to detect the miR-147 level and CCK-8. Flow cytometry and Transwell chamber were utilized to investigate the effects of miR-147b downregulation on cell proliferation, cell cycle and invasion in ESCC cells. Besides, target genes of miR-147b was confirmed by double luciferase reporter assay. Subsequently, qPCR and Western blot were used to examine the effects of miR-147b downregulation on NDUFA4 expression, and NDUFA4 expression and its correlation with miR-147b were investigated in ESCC tissues. Results: Relative level of miR-147b in ESCC tissues (3.03±0.27) and cells were markedly higher than that in para-carcinoma tissues (1.00±0.01) and normal esophageal epithelial cell, and the differences had statistical significance (P<0.01), and its high expression was closely associated with clinical staging, invasion depth, histological grading and lymph node metastasis(P<0.05). Importantly, clinical staging, lymph node metastasis and miR-147b may be an independent prognostic factor in ESCC. Moreover, miR-147b downregulation dramatically suppressed cell proliferation, arrested cell cycle in G0/G1 phase and reduced invasion ability in ESCC cells. Most importantly, NDUFA4 was a direct target gene of miR-147b, and miR-147b inhibitor evidently upregulated the expression of NDUFA4. Furthermore, NDUFA4 displayed low expression in ESCC tissues and its expression exhibited negative correlation with miR-147b expression. Conclusions: The downregulation of miR-147b expression significantly suppresses the proliferation and invasion abilities as well as alters cell cycle distribution in ESCC.

Abstract
AIM We aim to investigate the incidence and associated factors of vitamin D deficiency, a seldom reported factor, in patients with stages 1 and 2 chronic kidney disease (CKD) in southern China. METHODS We conducted a single-center observational study. Hospitalized patients over 14 years old, who were diagnosed with stages 1 and 2 CKD and had their serum 25-hydroxyvitamin D [25 (OH) D] measured, were included. Patients were divided into vitamin D deficient and non-deficient groups depending on the cutoff serum 25 (OH) D value of 37 nmol/L. Clinical and biochemical parameters were evaluated for associated factors of vitamin D deficiency by logistic regression. RESULTS A total of 118 patients were included, of which 62 (52.5%) were vitamin D insufficient and 47 (39.8%) were vitamin D deficient. Using multivariate binary logistic regression analysis, high serum level of gamma-glutamyl transpeptidase (GGT) (OR = 5.163; 95%CI, 1.105-24.130; P = 0.037), dyslipidemia (OR = 3.083; 95%CI, 1.029-9.243; P = 0.044), 24-hour urinary protein excretion (UPE) ≥3.5 g/24 hrs (OR = 5.010; 95%CI, 1.316-19.074; P = 0.018), and treatment with glucocorticoids (OR = 2.973; 95%CI, 1.093-8.084; P = 0.033) were independently associated with vitamin D deficiency. In addition, among different types of nephropathy, minimal change disease (MCD) had the highest incidence (85.7%) of vitamin D deficiency. CONCLUSION Poor vitamin D status is common in patients with stages 1 and 2 CKD in southern China. The incidence of vitamin D deficiency is 39.8%. High serum GGT level, dyslipidemia, 24-hour UPE ≥3.5 g/24 hrs, and treatment with glucocorticoids are independent associated factors of vitamin D deficiency.
