Abstract
Objective: To investigate the characteristics of frailty in the elderly male patients with chronic kidney disease (CKD) and the effects of renal function on the incidence of frailty. Methods: A total of 105 non-dialysis CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Their clinical data and laboratory indicators were collected. Frailty was defined according to Fried frailty criteria. According to the frailty scores, the participants were categorized as non-frail (n=37), intermediately frail (n=37) and frail (n=31). The association of frailty and the level of estimated glomerular filtration rate (eGFR) in the patients was analyzed using the model of multivariate Logistic regression. Results: Among the 105 patients, the mean age was 74 (68, 77) years old. The incidence of frail and intermediate frail was 35.2% (37/105) and 29.5% (31/105), respectively. Multivariate logistic analysis showed statistically significant associations of frailty with age (OR=1.14, 95%CI:1.08-1.20, P<0.001), body mass index (OR=0.87, 95%CI:0.79-0.95, P=0.001) and the level of eGFR (OR=0.98, 95%CI:0.96-0.99, P=0.003) in those patients. The incidence of frail in patients with eGFR<45 ml·min(-1)·(1.73 m(2))(-1) and 45-59 ml·min(-1)·(1.73 m(2))(-1) was 1.02 (OR=2.02, 95%CI: 1.06~3.87) and 0.84 (OR=1.84, 95%CI: 1.05-3.22) times higher than that of eGFR≥60 ml·min(-1)·(1.73 m(2))(-1), respectively. Conclusion: The incidence of frailty in the elderly patients with CKD is affected by many factors, such as age, body mass index and renal function, and increases with decreased renal function.

Abstract
Objective: To identify the therapeutic efficacy of lithium chloride (LiCl) on phosphatase and tensin homolog deleted on chromosome ten (PTEN)-deficient tumors. Methods: First, the Catalogue of Somatic Mutations in Cancer for mutation spectrum of human endometrial carcinoma samples was analyzed. Second, the relationship between PTEN abundance and LiCl inhibition of endometrial cancer cell lines using Pten(+/+) and Pten(-/-) mouse embryonic fibroblast (MEF) lines was investigated. Moreover, potential alterations of mammalian target of rapamycin (mTOR) signaling pathway after treatment with LiCl were checked.Last,LiCl's efficacy on PTEN null tumors was studied. Results: PTEN was mutated in 39% of endometrial carcinomas. LiCl preferentially inhibited the proliferation of PTEN-deficient endometrial carcinoma cells and MEFs. Furthermore, LiCl blocked PTEN-deficient tumor development. Mechanistically, LiCl down-regulated mTOR signaling. Conclusions: PTEN is the most frequently mutated gene in endometrial carcinoma.By targeting mTOR signaling pathway,LiCl is a promising regimen for the treatment of tumors with PTEN deficiency.

Abstract
Abstract Objective To explore the distribution of genetic structure of Y-SNP and Y-STR genetic markers in different ethnic groups and its application in forensic science. Methods SNaPshot minisequencing was used to detect the polymorphisms of 12 Y-SNP loci in 439 males from 6 ethnic groups, including Guangxi Han, Guangxi Jing, Guangxi Miao, Guangxi Yao, Guangxi Zhuang and Guangxi Dong. DNATyperTM Y26 kit was used to multiplex-amplify 26 Y-STR loci. The PCR products were analyzed by 3130xl genetic analyzer. The network analysis of Y-STR haplotype under the same Y-SNP haplogroup was analyzed by Network 5.0 software. Results Six haplogroups defined by 12 Y-SNP loci were detected in 6 ethnic groups, and 362 haplotypes were detected in 26 Y-STR loci. The haplotype diversity was 0.996 6. In the C haplogroup, the samples from Guangxi Yao, Guangxi Zhuang and Guangxi Dong were clustered on different branches; in the O1 haplogroup, those from Guangxi Zhuang, Guangxi Miao and Guangxi Jing were relatively independent and clustered separately; in the O2 haplogroup, some samples from Guangxi Miao and Guangxi Yao were gathered in a cluster. Conclusion Based on the Y-STR network analysis of samples with identical haplogroup of Y-SNP, some ethnic groups can be preliminarily distinguished, which could be used to infer male suspects' ethnic group through detecting their genetic markers left in the crime scene.

Abstract
Objective: To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. Methods: 530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients. Results: A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05). Conclusions: Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It's important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.

Abstract
Objective: To investigate the expressional levels and diagnostic values of miR-18a and miR-21 in esophageal carcinoma. Methods: The expressions of miR-18a and miR-21 in esophageal cancer tissues and adjacent tissues from 45 esophageal cancer patients, peripheral blood from 45 esophageal cancer patients and 50 healthy donors respectively were detected by RT-PCR. The expressions of miR-18a and miR-21 in normal esophageal epithelial cell HET-1A, esophageal cancer cell lines including ECA109, KYSE150 and TE1 were also detected. Chemiluminescence immunoassay was used to quantitatively detect the concentrations of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC), CYRFA21-1 and TPA (tissue polypeptide antigen) in peripheral blood serum from esophageal cancer patients and healthy controls. Meanwhile, the diagnostic effects of miR-18a and miR-21 on esophageal cancer were compared with those of tumor markers in serum. Results: The expression levels of miR-18a and miR-21 in esophageal cancer cells ECA109, KYSE150 and TE1 were 1.64±0.17, 1.62±0.19, 1.46±0.12 and 20.52±1.48, 6.73±0.73, 1.43±0.19, respectively, higher than those in normal esophageal epithelial cells (both P<0.01). The expressions of miR-18a and miR-21 in esophageal cancer tissues were 32.48±28.62 and 8.67±11.98, respectively, significantly higher than those in adjacent tissues (all P<0.001). The expression levels of miR-18a and miR-21 in peripheral blood of patients with esophageal cancer were 12.66±11.92 and 9.15±8.14, respectively, significantly higher than those in the normal control group (both P<0.001). The receiver operating characteristic (ROC) curve analysis showed that the area under the curve of miR-18a and miR-21 for diagnosis of esophageal cancer were 0.948 and 0.913 5, respectively. Compared with traditional esophageal tumor markers, the expressions of miR-18a and miR-21 were more sensitive in the diagnosis of esophageal cancer. The sensitivity and accuracy of the expressions of miR-18a and miR-21 combined with traditional esophageal tumor markers in diagnosis of esophageal cancer can be further improved to 97.8% and 68.4%, respectively. Conclusion: Our study reveals that the expressions of miR-18a and miR-21 play important roles in the diagnosis of esophageal cancer and may be potentially novel biomarkers.

Abstract
The three central phenomena of cuprate (copper oxide) superconductors are linked by a common doping level p*-at which the enigmatic pseudogap phase ends and the resistivity exhibits an anomalous linear dependence on temperature, and around which the superconducting phase forms a dome-shaped area in the phase diagram1. However, the fundamental nature of p* remains unclear, in particular regarding whether it marks a true quantum phase transition. Here we measure the specific heat C of the cuprates Eu-LSCO and Nd-LSCO at low temperature in magnetic fields large enough to suppress superconductivity, over a wide doping range2 that includes p*. As a function of doping, we find that Cel/T is strongly peaked at p* (where Cel is the electronic contribution to C) and exhibits a log(1/T) dependence as temperature T tends to zero. These are the classic thermodynamic signatures of a quantum critical point3-5, as observed in heavy-fermion6 and iron-based7 superconductors at the point where their antiferromagnetic phase comes to an end. We conclude that the pseudogap phase of cuprates ends at a quantum critical point, the associated fluctuations of which are probably involved in d-wave pairing and the anomalous scattering of charge carriers.

Abstract
Objective: To explore the psychological status and related factors in patients with precancerous of esophageal and gastric cardia in Linzhou of Henan. Methods: Clinical psycho-rating scale of Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS, score ≥50 points with symptoms of anxiety) and Self-Rating Depression Scale (SDS, score ≥53 points with the symptoms of depression) were applied to survey life events and psychological status of subjects who aged 40-69 years old and participated in"The Early diagnosis and Early Treatment"program in Linzhou cancer hospital from July 2015 to Jan 2016. Patients with lower intraepithelial neoplasia or high-grade intraepithelial neoplasia were selected as precancerous lesions (n=118), and patients with normal grade were selected as healthy controls (n=210). Compare the differences of the scores between the two groups, and the logistic regression model was used to analyze the related factors of precancerous lesions and psychological status of the study subjects. Results: Precancerous lesions included esophageal (72 cases), gastric cardia (40 cases), esophageal and cardia dual source (6 cases); Precancerous lesions and healthy controls aged (57.17±7.71) and (53.12±7.99) years old, the difference was statistically significant (P<0.001). The anxiety and depression scale showed that the scores of SAS and SDS scores in the precancerous lesions were (37.18±10.01), (40.44±8.37) points, and (34.02±6.63), (38.49±8.73) points in control group, the difference was statistically significant (P=0.002, 0.032). While the social support total score (38.26±5.26), and subjective support score (24.08±3.83) and objective support score (7.50±1.89) in control group were all higher than those of precancerous group (36.80±6.18, 23.01±3.93, 6.93±1.57), and the difference were statistically significant (P=0.024, 0.016, 0.004). In addition, the Logistic analysis showed that subjects with low objective social support, subjective social support and anxiety symptoms were more likely to develop precancerous lesions, and the OR were 0.81, 0.72 and 1.05, respectively (P=0.028, 0.005, 0.009). Conclusion: Social support, anxiety and depression status may be related to the occurrence and development of esophageal and gastric cardia precancerous lesions.

Abstract
Objective: To analyze whether heat-shock protein 90 (HSP90) be involved in a permanently abnormal activated JAK/STAT signaling in ATL cells in vitro. Methods: The effect of 17-AAG on proliferation of ATL cell lines HUT-102 was assessed using CCK8 at different time points. Cell apoptosis was measured by flow cytometry. The specific proteins HSP90, STAT5, p-STAT5 and JAK3 were detected by Western blotting. Results: Overexpression of HSP90 in HUT-102 cell lines was disclosed (P<0.05) , and constitutive activation of JAK3/STAT5 signaling was observed in HTLV-1-infected T-cell lines but not in normal PBMCs; Treatment of ATL cell lines with 17-AAG led to reduced cell proliferation, but there was no significant change in terms of cell proliferation when the concentration of 17-AAG between 2 000-8 000 nmol/L (P>0.05) . 17-AAG induced cell apoptosis in different time-points and concentrations. 17-AAG don't affect the expression of JAK3 gene. Conclusion: This study indicated that JAK3 as HSP90 client protein was aberrantly activated in HTLV-1-infected T-cell lines, leading to constitutive activation of p-STAT5 in JAK/STAT signal pathway, which demonstrated that HSP90-inhibitors 17-AAG inhibited the growth of HTLV-1-infected T-cell lines by reducing cell proliferation and inducing cell apoptosis.

Abstract
Objective: To observe the analgesic and sedative effect and safety of application of dexmedetomidine combined with remifentanil in dressing change of conscious patients with non-intubation in burn intensive care unit. Methods: Forty patients conforming to the study criteria hospitalized in our burn intensive care unit from April 2015 to April 2017 were selected. Prospective, randomized, and double-blind method was used for the design. Patients were divided into dexmedetomidine group and dexmedetomidine+ remifentanil group according to the random number table, with 20 cases in each group. Patients in the two groups were respectively given corresponding drugs during dressing change. The frequency and time of dressing change, Verbal Rating Scale (VRS) score of patients during dressing change (at drug administration for 25 minutes) and after dressing change (25 min after dressing change), Ramsay Sedation Score (RSS) during dressing change, satisfaction level for anesthesia of the patients and physicians after dressing change, dosage of remifentanil, and various adverse effects during and after dressing change were recorded. The heart rate, mean arterial blood pressure (MAP), respiratory rate, and pulse oxygen saturation (SpO2) before drug administration and at 10, 15, and 25 minutes after drug administration were also recorded. Data were processed with analysis of variance for repeated measurement, t test, chi-square test, and Fisher's exact probability test. Results: (1) Totally 38 patients completed the trial. There were no statistically significant differences between patients in two groups in gender, American Association of Anesthesiologist Grading, age, weight, and total burn area (χ2=0.230, 0.146, t=0.224, 0.351, 0.367, P>0.05). (2) The frequency of dressing change of patients in two groups were both 48 times. The time of dressing change and VRS scores during dressing change of patients in two groups were similar (t=0.821, 1.522, P>0.05). The VRS score of patients in dexmedetomidine+ remifentanil group after dressing change was (3.1±0.4) points, obviously lower than (3.8±0.8) points in remifentanil group (t=2.213, P<0.05). The RSS, satisfaction level scores for anesthesia of the patients and physicians after dressing change in dexmedetomidine+ remifentanil group were (3.13±0.32), (3.44±0.41), and (3.13±0.25) points, respectively, obviously better than (1.82±0.24), (2.71±0.23), (2.53±0.41) points in remifentanil group (t=2.226, 2.684, 7.702, P<0.01). The dosage of remifentanil of patients in dexmedetomidine+ remifentanil group was (282±19) μg, obviously less than (340±31) μg in remifentanil group (t=9.896, P<0.01). There were no statistically significant differences between patients in two groups in rates of respiratory inhibition and hypotension (χ2=0.211, 0.154, P>0.05). Compared with those in remifentanil group, the rates of nausea, vomiting, and other gastrointestinal symptoms of patients in dexmedetomidine+ remifentanil group were obviously reduced (P<0.05), but the rate of bradycardia was obviously increased (χ2=6.008, P<0.05). (3) There were no statistically significant differences between patients in two groups in heart rate, MAP, respiratory frequency, and SpO2 before drug administration (t=0.444, 0.892, 1.059, 1.039, P>0.05). The heart rates of patients in dexmedetomidine+ remifentanil group at 10, 15, and 25 minutes after drug administration were (83±11), (78±10), and (82±14) times per minute, respectively, significantly lower than (95±10), (87±12), and (89±12) times per minute in remifentanil group (t=5.592, 3.992, 2.630, P<0.05 or P<0.01). The MAP of patients in dexmedetomidine+ remifentanil group at 15 and 25 minutes after drug administration were (69.4±3.1) and (73.8±2.2) mmHg (1 mmHg=0.133 kPa), respectively, significantly lower than (75.4±3.0) and (78.1±3.5) mmHg in remifentanil group (t=9.181, 7.206, P<0.01). There were no statistically significant differences between patients in two groups in respiratory frequency at each time point after drug administration (t=1.489, 1.862, 1.963, P>0.05). The SpO2 of patients in dexmedetomidine+ remifentanil group at 15 minutes after drug administration was 0.972±0.018, obviously lower than 0.979±0.015 in remifentanil group (t=2.070, P<0.05). Conclusions: Application of remifentanil with small dosage has effective analgesia for conscious burn patients with non-intubation during dressing changes, however, adverse effects such as nausea and vomiting are likely to occur. Remifentanil combined with dexmedetomidine not only guarantee the analgesic effect, but also reduce the dosage of analgesics, improve the sedative effect and satisfaction of the patients for anesthesia, and reduce various adverse effects. However, it will increase the incidence of bradycardia and has some inhibition effect on circulation at the same time.

Abstract
Chitosan/montmorillonite intercalated composite (CTS/MMT) was used as an effective adsorbent for removal of reactive dyes, i.e. Reactive Black 5 (RB5), Reactive Red 136 (RR136), Reactive Yellow 145 (RY145) and Reactive Blue 222 (RB222). Taguchi method attached grey relational analysis was applied to determine the optimal adsorption conditions, including pH, initial concentration of dye, temperature, adsorbent dosage and contact time, for achieving simultaneous maximization of removal percentage and adsorption capacity. The percentage contribution of each adsorption condition was determined in the analysis of variance and showed that the most effective parameter in removal of RB5, RY145 and RB222 is the dye solution pH, whereas the initial concentration was the determining factor for optimum efficiency for the dye RR136. Under respective optimal condition, the removal percentages and adsorption capacity of four reactive dyes onto CTS/MMT were both found in the following order: RR136 > RY145 > RB5 > RB222. The maximum removal percentages of 78.8 and 49.5%, and the adsorption capacity of 315.20 and 123.75 mg/g were obtained for RR136 and RB222, respectively. The adsorption behaviors showed that the adsorption kinetics and isotherms were in best agreement with Avrami fractionary order model and the Toth isotherm, respectively.

Abstract
Objective: To observe the effect of Yiqi Wenyang Decoction on the infiltration and activation of NK cells in nasal mucosa of mouse model with allergic rhinitis (AR), and to explore the potential mechanism for effective intervention of AR with Yiqi Wenyang Decoction. Methods: Fourty-eight mice were randomly divided into blank group, model group, low, medium and high dose of Yiqi Wenyang Decoction group and Cetirizine group, with 8 rats in each group. After modeling of AR, the model group was filled with 0.9% sodium chloride solution. Yiqi Wenyang Decoction groups of each dose were given different concentrations of Yiqi Wenyang Decoction water extract, while the Cetirizine group was given aqueous solution of Cetirizine. The behavior, morphological changes of nasal mucosa and infiltration of NK cells in nasal mucosa were observed. The levels of IL-4 and INF-γ in nasal lavage fluid were measured. Besides, the drug safety was observed by acute toxicity test. Results: In the respect of behavioral scoring, middle and high dose of Yiqi Wenyang Decoction group were superior to the model group (number of sneezing: q value was 7.189, 8.748, respectively; number of scratching nose: q value was 12.074, 14.560, respectively; all P<0.05). In middle and high dose of Yiqi Wenyang Decoction group, the infiltration of NK cells and nasal lavage fluid IL-4 levels were lower than those in model group (IOD: q value was 10.073, 12.322, respectively; IOD/Area: q value was 10.954, 14.073, respectively; IL-4: q value was 4.705, 6.801, respectively; all P<0.05). There was no significant difference in nasal lavage fluid of INF-γ among each group (Fv=1.166, P>0.05). In acute toxicity test, no obvious poisoning symptoms and death occurred in mice. Conclusion: Yiqi Wenyang Decoction can control the nasal symptom, reduce the local NK cell infiltration of nasal mucosa and inhibit the expression of the 2-type cytokines released by NK cells, which may be related with the potential mechanism of effective intervention of AR with Yiqi Wenyang Decoction.

Abstract
Line coupling and line mixing effects have been calculated for several self-broadened NH3 lines in parallel bands involving an excited v 2 mode. It is well known that once the v 2 mode is excited, the inversion splitting quickly increases as this quantum number increases. In the present study, we have shown that the v 2 dependence of the inversion splitting plays a dominant role in the calculated line-shape parameters. For the v 2 band with a 36 cm-1 splitting, the intra-doublet couplings practically disappear and for the 2v 2 and 2v 2 - v 2 bands with much higher splitting values, they are completely absent. With respect to the inter-doublet coupling, it becomes the most efficient coupling mechanism for the v 2 band, but it is also completely absent for bands with higher v 2 quantum numbers. Because line mixing is caused by line coupling, the above conclusions on line coupling are also applicable for line mixing. Concerning the check of our calculated line mixing effects, while the present formalism has well explained the line mixing signatures observed in the v 1 band, there are large discrepancies between the measured Rosenkranz mixing parameters and our calculated results for the v 2 and 2v 2 bands. In order to clarify these discrepancies, we propose to make some new measurements. In addition, we have calculated self-broadened half-widths in the v 2 and 2v 2 bands and made comparisons with several measurements and with the values listed in HITRAN 2012. In general, the agreements with measurements are very good. In contrast, the agreement with HITRAN 2012 is poor, indicating that the empirical formula used to predict the HITRAN 2012 data has to be updated.
