Background::Exercise, as the cornerstone of pulmonary rehabilitation, is recommended to chronic obstructive pulmonary disease (COPD) patients. The underlying molecular basis and metabolic process were not fully elucidated.Methods::Sprague-Dawley rats were classified into five groups: non-COPD/rest ( n = 8), non-COPD/exercise ( n = 7), COPD/rest ( n = 7), COPD/medium exercise ( n = 10), and COPD/intensive exercise ( n = 10). COPD animals were exposed to cigarette smoke and lipopolysaccharide instillation for 90 days, while the non-COPD control animals were exposed to room air. Non-COPD/exercise and COPD/medium exercise animals were trained on a treadmill at a decline of 5° and a speed of 15 m/min while animals in the COPD/intensive exercise group were trained at a decline of 5° and a speed of 18 m/min. After eight weeks of exercise/rest, we used ultrasonography, immunohistochemistry, transmission electron microscopy, oxidative capacity of mitochondria, airflow-assisted desorption electrospray ionization-mass spectrometry imaging (AFADESI-MSI), and transcriptomics analyses to assess rectal femoris (RF). Results::At the end of 90 days, COPD rats’ weight gain was smaller than control by 59.48 ± 15.33 g ( P = 0.0005). The oxidative muscle fibers proportion was lower ( P < 0.0001). At the end of additional eight weeks of exercise/rest, compared to COPD/rest, COPD/medium exercise group showed advantages in weight gain, femoral artery peak flow velocity (Δ58.22 mm/s, 95% CI: 13.85-102.60 mm/s, P = 0.0104), RF diameters (Δ0.16 mm, 95% CI: 0.04-0.28 mm, P = 0.0093), myofibrils diameter (Δ0.06 μm, 95% CI: 0.02-0.10 μm, P = 0.006), oxidative muscle fiber percentage (Δ4.84%, 95% CI: 0.15-9.53%, P = 0.0434), mitochondria oxidative phosphorylate capacity ( P < 0.0001). Biomolecules spatial distribution in situ and bioinformatic analyses of transcriptomics suggested COPD-related alteration in metabolites and gene expression, which can be impacted by exercise. Conclusion::COPD rat model had multi-level structure and function impairment, which can be mitigated by exercise.

Objective To analyze the quality of the hospital preparation magnesium sulfate oral solution by using capability sixpack. Methods By using the capability sixpack of Minitab, the content of magnesium sulfate in the magnesium sulfate oral solution was used as an indicator to determine whether the magnesium sulfate composition reached a controlled state during the production process and whether the production process of magnesium sulfate oral solution was stable. Results The content of magnesium sulfate and the production process of magnesium sulfate oral solution was under control, but there were potential disadvantages. Based on the concept of risk management philosophy, The failure model and effect analysis (FMEA) were applied to the prospective management of potential risks. Conclusion The application of the capability sixpack in the quality analysis of the hospital preparation of magnesium sulfate oral solution is helpful for us to discover the potential risks under the controlled state of the production process, which is beneficial to the improvement of the preparation production process and the assurance of the quality of the preparation.

Objective: To investigate the anti-tumor effect of CTL cells on colon cancer xenograft in nude mice after knocking out the immune check point CTLA-4 by CRISPR/Cas9 technology. Methods: A specific small guide RNA (sgRNA) for CTLA-4 was designed to construct sgRNA/Cas9 plasmid, which was then transfected into CTL using a lentiviral vector to obtain CTL cells with CTLA-4 deletion (CTLA-4 KO CTL). The transfection efficiency of the plasmid and the deletion efficiency of CTLA-4 were verified. BALB/c nude mice were randomly divided into two groups to prophylactically inoculate CTLA-4 KO CTL (experimental group) or CTL (control group); 3 days later, the animals of two groups were inoculated with colon cancer cell line LS174-T to observe the tumor formation rate and tumor formation time. After constructing colon cancer xenograft model in nude mice, the animals were randomly divided into two groups, respectively treated with CTLA-4 KO CTL (experimental group) and CTL (control group) cells to observe the tumor growth volume and survival time of mice. The serum levels of TNF-α and IFN-γ in nude mice were detected. Results: sgRNAwas designed and CRSIPR/Cas9 system with lentivirus as vector was successfully constructed. CTL cells were transfected with the established CRSIPR/ Cas9 system, and the highest transfection efficiency was up to (28.80±0.62)%. After transfection, the deletion efficiency of CTLA-4 was detected by Flow cytometry. The CTLA-4 expression of CTLA-4 KO CTL group was significantly lower than that of CTL group [(0.91±0.25)% vs (42.70±2.72)%, P<0.05]. In prophylactic assay, the formation rate of colon cancer xenografts in the experimental group was significantly lower than that in the control group(33.33%vs100%,P<0.05). In treatment assay, the tumor volume in the experimental group was significantly inhibited compared with the control group ([503±23.9] vs [911.2±51.4] mm3, P<0.05), and the survivaltimeoftheexperimentalgroupwassignificantlyprolonged (mediansurvivaltime:78dvs42d,P<0.05); Moreover, the secretion levels of serumTNF-α([268.93±17.04]pg/mlvs[148.26±20.07]pg/ml,P<0.05) and IFN-γ(315.38±18.67 pg/ml vs 202.92±29.32 pg/ml, P<0.05) in the experimental group were significantly higher than those in the control group. Conclusions: The lentiviral vector CRSIPR/Cas9 system is an effective gene editing method; its successful deletion of CTLA-4 in CTL cells can significantly inhibit the tumor formation rate of colon cancer xenografts in nude mice and enhance the anti-tumor effect of CTLon colon cancer xenografts.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

OBJECTIVE： To investigate the relationship between ATP-binding cassette subfamily B member 1 （ABCB1） polymorphism and tacrolimus-related adverse drug reactions in renal transplant patients during perioperative period. METHODS： Totally 170 patients who underwent renal transplantation from Nov. 2014 to Mar. 2018 in our hospital as well as were tested for their ABCB1 C1236T （rs1128503）， ABCB1 G2677T/A （rs2032582） and ABCB1 C3435T （rs1045642） genotype were selected in this study. χ2 test was used to compare the incidence of tacrolimus-related ADR among patients with different genotypes. The related adverse reactions included digestive tract reaction， pulmonary infection， renal dysfunction， abnormal liver function， elevated blood sugar， elevated blood lipid and decreased white blood cells. Logistic regression model was used to analyze the unit point risk. The main haplotypes of the above genes were analyzed by PHASE software， and their correlation with tacrolimus-induced ADR was analyzed. RESULTS： Among 170 patients， 21 cases （12.3％） of CC type， 78 cases （45.9％） of CT type and 71 cases （41.8％） of TT type were detected by ABCB1 C1236T （rs1128503）. ABCB1 G2677T/A （rs2032582） test showed that 25 cases （14.7％） were GG type， 95 cases （55.9％） were GA+GT type and 50 cases （29.4％） were AA+AT+TT type. ABCB1 C3435T （rs1045642） test showed that 57 cases （33.5％） were CC type， 82 cases （48.2％） were CT type and 31 cases （18.3％） were TT type. There was no significant difference in the incidence of digestive tract reaction， pulmonary infection， renal dysfunction， elevated blood sugar， elevated blood lipid and decreased white blood cells among patients with different ABCB1 genotypes （P＞0.05）. However， there was significant difference in the incidence of abnormal liver function between ABCB1 C1236T （rs1128503） and ABCB1 C3435T （rs1045642） genotypes （P＜0.05）. There was no significant difference in the incidence of abnormal liver function among ABCB1 G2677T/A （rs2032582） genotypes （P＝0.069）， but P was lower than 0.1. Logistic regression analysis showed that ABCB1 C1236T （rs1128503） CC genotype [OR＝4.959， 95％CI （1.700， 14.468）， P＝0.003]， ABCB1 G2677T/A （rs2032582） GG genotype [OR＝3.500， 95％CI （1.164， 10.524）， P＝0.026] and ABCB1 C3435T （rs1045642） CC genotype [OR＝3.033， 95％CI （1.012， 9.095）， P＝0.048] were risk factors for tacrolimus-related abnormal liver function. ABCB1 CGC haplotype was the main haplotype. There was significant difference in the incidence of abnormal liver function caused by tacrolimus between ABCB1 CGC haplotype and non-ABCB1 CGC haplotype （P＝0.002）， and it was also a risk factor for tacrolimus-related liver dysfunction [OR＝3.173， 95％CI（1.512， 6.656）， P＝0.002]. CONCLUSIONS： The abnormal liver function of ABCB1 CGC haplotype kidney transplantation patients is more likely to occur when tacrolimus is administered during the perioperative period.

OBJECTIVETo evaluate systematically the short- and long-term outcomes between laparoscope-assisted transanal total mesorectal excision (LA-taTME) and laparoscopic total mesorectal excision (L-TME) in the treatment of mid and low rectal cancer.

METHODSLiteratures comparing LA-taTME with L-TME published from January 2014 to January 2018 were systematically selected through searching PubMed, Ovid, EMbase, Cochrane Library, CNKI and Wanfang databases. Literature screening and methodology quality evaluation were carried out by two surgeons independently. Randomized controlled trial (RCT) was evaluated by the modified Jadad rating scale, in which 1 to 3 and 4 to 7 were considered as low and high quality,respectively(total scores: 7). Non-randomized controlled trial (NRCT) was assessed by the modified Newcastle Ottawa Scale (NOS), in which 1 to 3, 4 to 6, and 7 to 9 were defined as low, moderate, and high quality, respectively (total score: 9). Ratio of incomplete mesorectum, positive rate of circumferential resection margin (CRM), number of harvested lymph node, distance of distal resection margin, operation time, intraoperative blood loss, morbidity of postoperative complication, conversion rate, hospital stay, recurrence, 2-year disease-free survival (DFS) and 2-year overall survival (OS) were compared and analyzed by using Stata/SE12.0 software.

RESULTSFourteen studies including 1 RCT and 13 NRCTs were enrolled finally. Among them, the RCT with a score of 6 was considered to be of high quality; all NRCTs (2 with 6 stars, 5 with 7 stars, and another 6 with 8 stars) were indicative of moderate to high quality; 450 patients underwent LA-taTME and 498 patients underwent L-TME. No significant differences were observed in terms of age, gender, tumor location and TNM stage between two approaches (all P>0.05). Compared to L-TME, LA-taTME had lower ratio of incomplete mesorectum (RR=0.53, 95%CI: 0.31 to 0.93, P=0.026), lower positive rate of CRM (RR=0.50, 95%CI: 0.29 to 0.86, P=0.012), lower conversion rate(RR=0.48, 95%CI: 0.26 to 0.86, P=0.014), lower morbidity of postoperative complication (RR=0.81, 95%CI: 0.67 to 0.99, P=0.036) and less intraoperative blood loss (SMD=-0.38, 95%CI:-0.68 to -0.08, P=0.013). While the differences between two groups had no statistical significance in terms of operative duration, number of harvested lymph node, distance of distal resection margin, hospital stay, overall recurrence, 2-year DFS and 2-year OS (all P>0.05).

CONCLUSIONThe short- and long-term outcomes of LA-taTME and L-TME for the treatment of mid and low rectal cancer are comparable, while LA-taTME can reduce the ratio of incomplete mesorectum, positive rate of CRM, conversion rate, and morbidity of postoperative complication, and intraoperative blood loss.

Objective To explore the demands of schizophrenics and their primary caregivers for knowledge of mental health during rehabilitation period,so as to provide some references for improving their mental health knowledge.Methods Using the convenience sampling method,49 schizophrenics and 59 primary caregivers completed the general information questionnaire and needs for knowledge of mental health questionnaire.Results The total score of demands for knowledge of mental health of schizophrenics was (55.83±19.29),while the total score of caregivers was (64.88±19.83)(t=-2.376,P=0.019). Conclusions Demands for mental health knowledge of schizophrenics and their primary caregivers are different. Implementation of health education programs should be targeted and individualized.

Objective To investigate needs of caregivers of patients with schizophrenia for mental health knowledge and provide the scientific evidence for formulating the general intervention to improve the caregivers′mental health knowledge and skills . Methods Sixty-five caregivers of the patients with schizophrenia participated in the survey by a general state questionnaire and the requirement to mental health knowledge and skill questionnaire using the convenience sampling method. The survey included mental illness knowledge drug, knowledge rehabilitative therapy and self-adjustment. Results Among all the items of the questionnaire, the 3 items they needed most was mental illness knowledge, the preventing method and the symptoms of the recurrent diseases. The 3 items they needed most in respect of drug knowledge were what examinations are needed when taking special drugs, the adverse reactions of the antipsychotic drugs and the importance of persisting in taking drugs. The 3 they needed most in respect of rehabilitative therapy were the relationship between psychology and disease rehabilitation, the role of mental treatment and the role of work-entertainment therapy. The 3 items they needed most in respect of self-adjustment included sleep adjustment, self-adjustment of affects and self-management of daily life and instructions on dieting. Conclusions The caregivers′mental health knowledge and skills are not enough. Therefore, their mental health knowledge and skills should be strengthened so that they can take better care of the patients to realize comprehensive rehabilitation of patients.

Objective To explore the methods and effectiveness of using nurses as standardized patient ( NSP) in junior nurses′hanging and choking rescue care training. Methods This study selected four nurses as NSPs, based on Huaxi Hospital′s NSP screening criteria. A total of 60 nurses whose psychiatric nursing age were beyond three years were randomly divided into experimental group and control group, with 30 members each. The nurses in the experimental group were treated with NSP method, while the control group was trained in the regular way. After that, the effects of training were evaluated by Dundee Ready Education Environment Measure ( DREEM ) . The theory and clinical skills examination and training satisfaction were surveyed. Results The theory test scores of the two groups after training were significantly higher than those before training (P<0. 05), and the scores of the experimental group was higher than that of the control group, but there was no significant difference (P>0. 05). The total score of DREEM, and the perception of learning, course organizers and academic self-perception score of DREEM of the experimental group were significantly higher than those of the control group (t=7. 086, 9. 443, 10. 462, 8. 620, respectively;P<0. 05). The score of choking rescue skills of the experimental group was significantly higher than that of the control group ( t=2. 759,P<0. 05). But the score of hanging rescue skills of the experimental group was not significantly higher than that of the control group (P>0. 05). There was no significant difference in the satisfaction between the two groups (P>0. 05). Conclusions The application of NSP in hanging and choking rescue care training can improve the teaching environment, increase nurses′choking rescue care skills, but no difference is found in the theory examination and hanging rescue care skills between the two groups.

Objective To discuss the improvement of drug attitude and its influence factors in Schizophrenia inpatients. Methods A total of 185 schizophrenic inpatients were assessed the quality of life and drug attitude, and improvement of them at their admission and before their discharge by life satisfactions rating scales ( SQLS ) and drug attitude inventory ( DAI ) respectively. The Spearman correlation analysis and regression analysis were used to analyze the relationship among the differential value of DAI and SQLS, and demographic data. Results The SOLS scores of all patients dropped down before discharge comparing with scores of admission, in which social psychological dimension was ( 28. 7 ± 17. 0 ) score, dynamic energy dimension (44. 8 ± 14. 5) score, side effect symptom dimension (19. 2 ± 18. 7); the score of DAI increase to (3. 5 ± 4. 6) (t = -5. 831, -12. 112, -7. 373, 9. 875;P <0. 01). The correlation analysis presented gender, each dimension of SQLS improvement had bound with DAI improvement; liner regression analysis revealed that the improvement of dynamic energy and side effects symptom impacted on the improvement ( P<0. 05). Conclusions The improvement of quality of life in schizophrenic inpatients influences the improvement of attitude to taking medication, especially the more improvement of dynamic energy level and side effects symptom. The more quality of life improves, the more improvement of taking medication attitude.
