Abstract
Osteoarthritis (OA) is a complicated degenerative disease that affects whole joint tissue. Currently, apart from surgical approaches to treat late stage OA, effective treatments to reverse OA are not available. Thus, the mechanisms leading to OA, and more effective approaches to treat OA should be investigated. According to available evidence, the PI3K/AKT/mTOR signaling pathway is essential for normal metabolism of joint tissues, but is also involved in development of OA. To provide a wide viewpoint to roles of PI3K/AKT/mTOR signaling pathway in osteoarthritis, a comprehensive literature search was performed using PubMed terms 'PI3K OR AKT OR mTOR' and 'osteoarthritis'. This review highlights the role of PI3K/AKT/mTOR signaling in cartilage degradation, subchondral bone dysfunction, and synovial inflammation, and discusses how this signaling pathway affects development of the disease. We also summarize recent evidences of therapeutic approaches to treat OA by targeting the PI3K/AKT/mTOR pathway, and discuss potential challenges in developing these strategies for clinical treatment of OA.

Abstract
The Arabidopsis trichome is a polyploid epidermal cell resulting from multiple rounds of endocycles. The CYCLIN-DEPENDENT KINASE INHIBITOR (CKI) family proteins are core cell cycle regulators that promote the endocycle. CONSTITUTIVE EXPRESSION OF PR GENES 5 (CPR5) is a plant-specific nucleoporin. It has been found that two Arabidopsis CKI, SIAMESE (SIM) and SIAMESE-RELATED 1 (SMR1), function downstream of CPR5 to activate plant effector-triggered cell death. The sim smr1 double mutants form multicellular and clustered trichomes, while the cpr5 mutants produce dead and branchless trichomes. This study explored roles of the CPR5-CKI signalling pathway in trichome cell cycle transition. To examine the underlying mechanism of how cell cycle transition is regulated in plant trichomes, Trypan blue staining, flow cytometry, scanning electron microscopy (SEM) and nuclear DNA measurement were conducted. The native promoter-driven CKI and GUS fusion reporter showed that both SIM and SMR1 proteins were preferentially expressed in trichomes. The cpr5-induced dead and branchless trichomes were fully suppressed by the sim smr1 double mutant, suggesting that SIM and SMR1 function downstream of CPR5 in trichome development. Flow cytometry analysis showed that as compared to the number of 2C (C = DNA content in a haploid nucleus) cells, the number of 4C cells significantly increased, whereas that of polyploidy cells (8C and 16C) dramatically decreased in the cpr5 mutant. The elevated 4C/2C ratio in the cpr5 mutant is consistent with de-repression of pro-endocycle regulators SIM and SMR1. The polyploidy cells (8C and 16C) may be selectively targeted to cell death, which is therefore attributed to the branchless trichomes in the cpr5 mutant. Nuclear DNA content analysis demonstrated that the nuclear DNA content of trichomes in the cpr5 sim mutant was significantly higher than in the sim mutant, indicating that CPR5 is a negative endocycle regulator in trichomes. This study reveals that the CPR5-CKI signalling pathway controls trichome cell cycle transition and excessive endocycles are required for cell death in plant trichomes.

Abstract
Objective: To investigate the safety and efficacy of transcatheter perforation of pulmonary valve by micro-guidewire and balloon dilation in the treatment of neonatal pulmonary atresia with intact ventricular septum (PA-IVS). Methods: The retrospective study included 21 neonates (14 males and 7 females) with PA-IVS who underwent transcatheter micro-guidewire pulmonary valve perforation and balloon dilation in Xinhua Hospital from January 2012 to December 2018. All patients underwent the pulmonary valve perforation by micro-guidewire through the Simmons catheter. During the follow-up period at 1, 3, 6, 12 months postoperatively and annually thereafter, the operative efficacy and the development of the right ventricle (RV) were evaluated by echocardiography. Statistical analyses were performed using t test. Results: A total of 21 neonates with PA-IVS were enrolled, and 13 cases were diagnosed prenatally. The median age of surgery was 6 days, the weight was (3.2±0.5) kg. The balloon/valve ratio was 1.19±0.12, and the RV pressure measured by catheter was (121±33) mmHg (1 mmHg=0.133 kPa) . The immediate postoperative RV pressure was (47±13) mmHg. The median follow-up time was 30 months. All the cases enrolled achieved biventricular circulation without death and serious complications. According to the last follow-up data including 16 cases who were followed up for 1 year or longer, the pulmonary artery transvalvular pressure was (29±15) mmHg. The postoperation ratio of right to left ventricular transverse diameter was significantly higher than that before operation (0.86+0.10 vs. 0.73+0.13, t=-2.96, P=0.006). Compared with preoperative data, the postoperation pulmonary valvular diameter Z-score was significantly higher (-1.41±0.89 vs. -2.83±1.06, t=-3.65, P=0.001) and the tricuspid valvular diameter Z-score was significantly higher (-0.52±0.29 vs. -1.34±0.81, t=-3.55, P=0.001). Conclusion: Transcatheter perforation of pulmonary valve by micro-guidewire and balloon dilation is a safe and effective initial therapy for neonatal PA-IVS.

Abstract
Objective: To evaluate the effect of dexmedetomidine on lung injury and CCAAT/enhancer-binding protein homologous protein (CHOP) expression in elderly patients with lung cancer undergoing thoracoscopic lobectomy. Methods: A total of 120 elderly patients with lung cancer who underwent elective thoracoscopic lobectomy were selected from the Second Affiliated Hospital of Zhengzhou University from October 2018 to March 2019. The random phenotype was divided into dexmedetomidine group (group D, n=60) and control group (group C, n=60). The elapsed time before postoperative awake and spontaneous breathing recovery and agitation occurrence were recorded. The mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SPO(2)), oxygen partial pressure (PaO(2)), alveolar-arterial oxygen partial pressure difference[P(A-a)O(2)], end-tidal carbon dioxide partial pressure (P(ET)CO(2)), and airway pressure peak (P(peak)) were recorded before the anesthetic induction (T(0)), immediately after tracheal intubation (T(1)), immediately after unilateral pulmonary ventilation(T(2)), 1 hour after unilateral pulmonary ventilation (T(3)), immediately after bilateral pulmonary ventilation (T(4)), and at the end of surgery(T(5)). The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-8, IL-10, super oxide dismutase (SOD) and malondialdehyde (MDA)were compared at the time of T(0), T(1), T(2), T(3), T(4) and T(5) in two groups. The ratios of alveolar damage (IQA), apoptotic index (AI), and the expression of CHOP mRNA and their protein in lung tissue were detected. Results: The recovery time of conscious and spontaneous breathing in group D were significantly shorter than that in group C (P<0.05). The MAP and HR of the two groups at T(1)-T(5) were significantly lower than those at T(0)(P<0.05).The levels of P(peak) in group C at T(3)-T(5) was significantly higher than those in group D (P<0.05). The SpO(2) values in the group D at T(1)-T(5) were significantly higher than those in group C (P<0.05). The P(A-a)O(2) values in the group D at T(1)-T(5) was significantly lower than those in group C (P<0.05).The levels of IL-6, IL-8 and MDA in group D at T(1)-T(5) were significantly lower than those in group C(P<0.05). The levels of IL-10 and SOD in group D at T(1)-T(5) were significantly higher than those in group C (P<0.05). The values of IQA, AI, and the expression of CHOP mRNA and their protein in the two groups at T(4) were significantly higher than those at T(2) (P<0.05). The values of IQA, AI, and the expression of CHOP mRNA and their protein in group D at T(4) were significantly lower than those in group C (P<0.05). Conclusions: Dexmedetomidine could attenuate the extent of lung injury in elderly patients with lung cancer undergoing thoracoscopic lobectomy. The pulmonary protective mechanism could be related to the inhibition of inflammatory factors in dexmedetomidine, improving oxidative stress and reducing Chop-mediated apoptosis of lung tissue by the protein.

Abstract
Forecasting the trajectory of social dynamic processes, such as the spread of infectious diseases, poses significant challenges that call for methods that account for data and model uncertainty. Here we introduce an ensemble model for sequential forecasting that weights a set of plausible models and use a frequentist computational bootstrap approach to evaluate its uncertainty. We demonstrate the feasibility of our approach using simple dynamic differential-equation models and the trajectory of outbreak scenarios of the Ebola Forecasting Challenge. Specifically, we generate sequential short-term forecasts of epidemic outbreaks by combining phenomenological models that incorporate flexible epidemic growth scaling, namely the Generalized-Growth Model (GGM) and the Generalized Logistic Model (GLM). We rely on the root-mean-square error (RMSE) to quantify the quality of the models' fits during the calibration periods for weighting their contribution to the ensemble model while forecasting performance was evaluated using the RMSE of the forecasts. For a given forecasting horizon (1-4 weeks), we report the performance for each model as the percentage of the number of times each model outperforms the other models. The overall mean RMSE performance of the GLM and the GGM-GLM ensemble models outcompeted that of participant models of the Ebola Forecasting Challenge. We also found that the ensemble model provided more accurate forecasts with higher frequency than the GGM and GLM models, but its performance varied across forecasting horizons. For instance, across all of the Ebola Challenge Scenarios, the ensemble model outperformed the other models at horizons of 2 and 3 weeks while the GLM outperformed other models at horizons of 1 and 4 weeks.

Abstract
Abstract Objective To explore the relationship between the electrical conductivity (EC) and biochemical indicators of rat cerebrum tissues and postmortem intervals (PMIs) and discuss the mechanism of applying EC to infer PMI. Methods Forty healthy Sprague-Dawley rats were sacrificed and stored in an environment of about 25 ℃. The whole cerebrum tissues of rats were removed respectively at different PMIs of 0, 1, 2, 3, 4, 5, 6, and 7 d, and then made into homogenized impregnation solution. The EC and related biochemical indicators (potassium, sodium, chloride, calcium, inorganic phosphorus, magnesium, uric acid, urea nitrogen and creatinine) in cerebrum tissue impregnation solution were determined, and the relationships among EC in impregnation solution, related biochemical indicators and PMI were analyzed. Results The EC in cerebrum tissues increased gradually with the extension of PMI, and the content of uric acid, urea nitrogen and inorganic phosphorus in its impregnation solution also increased gradually with the extension of PMI. The correlation of EC, uric acid, urea nitrogen, and inorganic phosphorus with PMI was relatively good (R2 was 0.95-0.99), and there was a linear correlation between the content change of uric acid, urea nitrogen, inorganic phosphorus and EC (R2 was 0.97-0.99). The changes of the other 6 kinds of biochemical indicators with the extension of PMI within 7 d after the rats' death were non-significant (P>0.05). Conclusion The correlation between EC in cerebrum tissues, uric acid, urea nitrogen, inorganic phosphorus and PMI were relatively good, and combining various indicators can also improve the accuracy of PMI estimation.

A total of 476 FSWs aged 16 years and above were recruited from entertainment venues, and the information about their demographic characteristics, condom use negotiation and condom use were collected by using questionnaires. Logistic regression model was used to analyze related factors of condom use after negotiation between FSWs and clients unwilling use condom. Results: A total of 852 FSWs who aged (24.29±8.44) years old participated in the survey. In past month, 499 FSWs had negotiation for condom use with unwilling clients (58.6%, 499/852), after negotiation, 441 FSWs (88.4%, 441/499) had consistent condom use in each sex with the clients. In the past one month, 99 FSWs had negotiation for unwilling use condom with regular sex partners (14.4%, 99/687), after negotiation, 54 FSWs (54.5%, 54/99) had consistent condom use in each sex with regular sex partners. Among the FSWs, 266 (53.3%, 266/499) reported that they could say "It is a mandatory requirement" to persuade clients who were unwilling to use condom. 97(19.4%, 97/499) reported that they could say "There is risk for infection" to persuade clients who were unwilling to use condoms. 115 (23.1%,115/499) reported that they could say "It is a mandatory requirement" and "there is risk for infection" to persuade their unwilling clients to use condoms. 21 (4.2%, 21/499) reported that they used other strategies. 22 (4.4%, 22/499) felt that it was difficult to persuade clients to use condoms. Multivariate logistic regression analysis showed that compared with FSWs who felt difficult in persuading clients to use condoms, FSWs who felt moderate difficulty were more likely to have consistent condom use after negotiation (OR=4.00, 95%CI: 1.55-10.32) and FSWs who felt easy in persuading clients to use condoms were also more likely to have consistent condom use (OR=30.17, 95%CI: 3.22-282.44). Compared with FSWs used other strategies to persuade their clients to use condoms, FSWs who said it was a mandatory requirement were more likely to have consistent condom use after negotiation (OR=4.44, 95%CI: 1.41-14.01) and FSWs who said it was a mandatory requirement and there was risk for infection were also more likely to have consistent condom use (OR=5.52, 95%CI: 1.55-19.73). Conclusions: Negotiation for condom use increased the rate of condom use in FSWs in sex with clients who were unwilling to use condom. The negotiation strategy of "It is a mandatory requirement" would promote condom use in FSWs in sex with clients who were unwilling to use condom. Besides, the negotiation strategy of saying "there is risk for infection" had additional effects.

Abstract
Due to the continuous improvement on HIV surveillance system and the diversity of data sources, various methodologies on estimation and projection of HIV/AIDS present greater contribution in exploring the natural history and related burden of HIV in the future. Different kinds of methods have been developed by professionals, both at home and abroad. This paper reviews the rationale, requirement, application, strength and limitation of the related methodologies that have been widely used in this field, to provide reference and evidence for the application and selection of related methodologies in the future.
