Objective:
To evaluate the feasibility of autoregressive integrated moving average with explanatory variables ( ARIMAX ) model including meteorological factors on the prediction of influenza-like illness ( ILI ), so as to provide a basis for the monitoring and early warning of influenza.
Methods:
The ILI data reported by four sentinel hospitals in Yuhang District of Hangzhou from the 1st week of 2014 to the 26th week of 2018 was collected, as well as the meteorological data during the same period. The ARIMAX model was established using the percentage of ILI cases in total outpatients ( ILI% ) data from the 1st week of 2014 to the 52nd week of 2017 and the meteorological factors selected by Lasso regression model. The ILI% from the 1st to 26th week of 2018 was predicted and compared with the actual values to verify the ARIMAX model.
Results:
From the 1st week of 2014 to the 26th week of 2018, a total of 60 419 cases of ILI were reported by the four sentinel hospitals of Yuhang District, with ILI% of 1.29%. Lasso regression analysis showed that there was a positive correlation between weekly average absolute humidity and ILI% ( r=27.769 ), and a negative correlation between weekly average temperature and ILI% ( r=-0.117 ). The ARIMAX (1, 0, 0) ( 1, 0, 0 )12 with weekly average temperature and absolute humidity was selected as the optimal model, with the Bayesian information criterion (BIC) value of 81.30 and the mean absolute percentage error (MAPE) value of 15.77%. The MAPE value of the ARIMAX model predicting the ILI% from 1st to 26th week of 2018 were 43.75%.
Conclusion
The ARIMAX model including meteorological factors can be used to predict the prevalence of ILI, but the accuracy needs to be promoted.

Objective: To systematically assess the effectiveness and safety of using acupuncture-moxibustion therapy alone to treat adult overactive bladder (OAB) by taking oral Western medication solely as the control, and to provide evidence-based reference for acupuncture-moxibustion treatment of OAB. Methods: A systemic search was conducted through China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), PubMed, Cochrane Library, and Excerpta Medica Database (EMBASE). RevMan 5.3 was used for meta-analysis. Statistical descriptions were made using standardized mean difference (SMD), confidence interval (CI), and risk ratio (RR). Results: Eight randomized controlled studies were finally recruited and were analyzed after being grouped according to intervention methods. Regarding urinary symptoms, compared with sole use of oral Western medication, acupuncture plus moxibustion can more effectively reduce 24 h urinary frequency [P=0.01, SMD=-0.57, 95%CI (-1.02, -0.12)], 24 h nocturia frequency [P=0.03, SMD=0.49, 95%CI (0.05, 0.94)], and OAB syndrome score (OABSS) [P<0.001, SMD=-3.67, 95%CI (-4.48, -2.86)]. Acupuncture combined with moxibustion and oral Western medication work equivalently in comparing 24 h urinary urgency frequency [P=0.38, SMD=-0.17, 95%CI (-0.57, 0.22)], 24 h urgent incontinence frequency [P=0.25, SMD=0.26, 95%CI (-0.18, 0.70)], and single voiding volume [P=0.22, SMD=1.15, 95%CI (-0.70, 3.00)]. There were no significant differences between acupuncture/electroacupuncture and oral medication in comparing 24 h urinary frequency [P=0.46, SMD=0.07, 95%CI (-0.12, 0.26)], 24 h urinary urgency frequency [P=0.18, SMD=0.70, 95%CI (-1.71, 0.32)], 24 h nocturia frequency [P=0.46, SMD=-0.71, 95%CI (-2.60, 1.17)], 24 h urgent incontinence frequency [P=0.08, SMD=-0.22, 95%CI (-0.48, 0.03)], single voiding volume [P=0.09, SMD=0.17, 95%CI (-0.02, 0.36)], or OABSS [P=0.96, SMD=-0.07, 95%CI (-2.65, 2.52)]. Compared with oral Western medication, moxibustion can more effectively reduce 24 h urinary frequency [P<0.001, SMD=-6.53, 95%CI (-7.65, -5.44)] and 24 h urinary urgency frequency [P<0.001, SMD=-1.6, 95%CI (-2.85, -0.36)]. In comparing the adverse reaction rate, acupuncture-moxibustion was associated with a lower rate compared with oral medication [P=0.002, RR=0.07, 95%CI (0.01, 0.37)], but the difference was statistically insignificant between acupuncture/electroacupuncture and oral medication [P=0.40, RR=0.57, 95%CI (0.16, 2.12)]. Conclusion: Acupuncture-moxibustion is equivalent to the sole use of oral Western medication in improving urinary symptoms in OAB patients and has a higher safety rating.

BACKGROUND:The reported time of bone marrow mesenchymal stem cel s induced to differentiate into chondrocytes is different. Few studies have observed and compared the cel s’ dynamic transformation during the induction process.
OBJECTIVE:To observe the dynamic differentiation and the mature time of rabbit bone marrow mesenchymal stem cel s which were directional y induced to chondroblasts for 8, 11, 14, 17, 20 days.
METHODS:Bone marrow was aspirated from the femur of New Zeal rabbits, and bone marrow mesenchymal stem cel s were isolated by gradient centrifugation. After cultivation and amplification, bone marrow mesenchymal stem cel s at passage 3 were directional y induced to chondrocytes by the serum-free medium containing transforming growth factor beta-1. The experiments were divided into five groups according to different induction time points:8 days, 11 days, 14 days, 17 days, 20 days. Then cel ular morphology, toluidine blue staining, typeⅡ col agen immunohistochemistry, aggrecan content in induction medium, and chondrogenic differentiation in each group were observed and compared.
RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s had apparently transformed in morphology at 8 days of induction, and presented obvious chondrocytes’ morphology at 14 days. The aggrecan in induction medium could be detected at a low level at 4 days, significantly increased at 8 days, and maintained slow increasing at 20 days. At 14 days, the metachromatic particles could be found by toluidine blue staining, and the col agen type Ⅱimmunohistochemistry was significantly positive in cel climbing slice. Experimental findings indicate that, bone marrow mesenchymal stem cel s that are monolayer cultured in a high density can be induced into chondroblasts at the effect of transforming growth factor beta-1 and other factors. There are a few chondroblasts in the early induction process, then cel s begin to have chondrocytes morphology and function after induced for 8 days, and may differentiate to mature chondrocytes at 14 days. In addition, they can keep a high biological activity in the induction process.

Objective To explore the alteration of brain pain functional areas in patients with functional dyspepsia (FD) irritable bowel syndrome (IBS) overlap by rectal balloon volume stimulation and magnetic resonance imaging (MRI) and the differences with IBS alone patients and healthy individuals were compared.Methods A total of 11 IBS alone patients,16 IBS overlapped with FD patients (IBS-FD) and 10 healthy controls were recruited.Sensory thresholds and visual analogue scale (VAS) were recorded during the rectal balloon air injection process. The changes of brain activated areas were analyzed by functional MRI (fMRI) when the rectum was stimulated at the volume of 50,100 and 150 ml.The data were analyzed by least significant difference (LSD) test.Results Under rectal volumetric stimulation,the sensory thresholds of IBS-FD group and IBS alone group were (53.14 ± 16.05) ml and (59.20 ± 20.55) ml and the difference was not statistically significant (LSD test,P>0.05).There was no significant difference in VAS score between IBS alone group and IBS-FD group (LSD test,P>0.05).Rectal stimulated under different volume,the results of fMRI indicated the activation of anterior cingulated cortex, dorsolateral prefrontal cortex,postporietal cortex,thalamus and insular cortex in both IBS alone group and IBS-FD group.And there was no significant difference in activated areas and intensity between IBS alone group and IBS-FD group (LSD test,P>0.05).Conclusions There was no significant difference in activations of brain areas between IBS alone and IBS-FD patients under rectal volumetric stimulation. Under rectal volumetric stimulation,although symptoms overlapped,there was no evidence of the overlap of braingut axis and visceral hypersensitivity between IBS alone and IBS-FD.

Objective To investigate the effect of early enteral nutrition combined with probiotics on the nutritional status of patients with severe head injury. Methods Thirty-five patients with severe head injury were randomized into early enteral nutrition group ( control group, n = 18 ) and early enteral nutrition combined with probiotics group (observational group, n = 17). All the patients received enteral nutrition via nasogastric tube within 24-48 hours following admission. Hemoglobin, lymphocyte count,plasma concentrations of total protein, albumin, prealbumin, cholinesterase, and fasting blood glucose were determined before enteral nutrition and at days 8, 15, 21 after enteral nutrition. Arm circumference (AC), triceps skinfold thickness (TSF) and ann muscle circumference ( AMC ) were measured at the same time points. Gastrointestinal reactions as well as the time to first defecation were recorded. Glasgow coma scale (GCS) was assessed. Results There was no difference in terms of hemoglobin, lymphocyte count, plasma concentrations of total protein, prealbumin, and GCS score at each time point between the two groups ( P > 0. 05 ). At day 8 after enteral nutrition, the patients in the observational group exhibited significantly lower level of fasting blood glucose than those in the control group (P < 0.05 ). At day 15,the concentration of plasma cholinesterase in the observational group was significantly higher than that in the control group ( P < 0. 05 ). At day 21, the observational group showed a tendency in increase of plasma albumin level in comparison with the control group( P = 0. 054), and the decrease of AC and AMC was obviously lower than that in the control group ( P <0. 05 ) compared with pre-enteral nutrition. The observational group showed less gastro-oesophageal reflux and constipation as well as earlier time to first defecation compared with the control group ( P < 0. 05,0. 01 ). Conclusion Compared with the ordinary enteral nutrition, the enteral nutrition combined with probiotics can attenuate metabolic disorders and improve the nutritional status of the patients with severe head injury.

Objective To compare the efficacy and the side-effect of three different ways in treating the patients with malignant pleural effusion. Methods 98 patients histologically proved malignant pleural effusion were randomly divided into three groups, bleomycin group(BLM), bleomycin with mycobacterium group( BLM + UTL) and blemycin with intertleukino2 ( BLM +IL). 31 patients were treated with bleomycin intrapleural injection in BLM group,32 patients were treated with bleomycin and Utilin's(mycobacterium) intrapleural injection in BLM + ULL group and 35 patients were treated with bleomycin and intertleukin-2 intrapleural injection in BLM + IL group. The therapeutic efficacy, change of performance and side effects were compared among the three groups after one period of treatment. The changes of CEA and TNF in the pleural effusion were examined before and after treatment. Results The therapeutic efficacy and performance improvement were higher in BLM+UTL and BLM+IL group than that of BLM group(P<0. 05) ,the pleural CEA of post-treatment in three groups were lower than that of pre-treatment(P<0.01) ,the CEA after treatment in BLM+UTL group and BLM+IL group was lower than that of BLM group(P<0. 01,respectively). The pleural TNF of post-treatment in BLM+UTL and BLM+IL groups was higher than that of pre-treatment(P<0. 01 ) in BLM group. The pleural TNF of post-treatment in BLM+UTL and BLM+IL group was higher than that of BLM group ( P<0. 01 ). Conclusion Intrapleural injection of mycobacterium with bleomycin or interlekin-2 with bleomycin has better efficacy than using bleomycin only in treating malignant pleural effusion.
