ObjectiveTo establish a mutation library of rifampicin resistance gene rpoB. MethodsThe ΔrpoB attB：：rpoB strain of Mycobacterium smegmatis （M. smegmatis） be constructed by homologous recombination and L5 attB phage integration site exchange. Based on the L5 attB plasmid exchange system and resistance selection medium， 48 clones are selected to verify plasmid replacement efficiency. Degenerate primers are designed every 3 bases in the rifampicin resistance determining region （RRDR）， and a full-coverage mutation library of 81 bases in RRDR region is obtained by PCR amplification. The library fragments are seamlessly cloned into the vector and transformed into Escherichia coli （E. coli）to form an E. coli mutation library. Based on the principle of plasmid exchange， the mutant plasmid library is transformed into the M. smegmatis strain ΔrpoB attB：：rpoB， and the original L5 attB site plasmid is replaced to form the M. smegmatis mutant library. The genotype of the library are determined by genome extraction， library construction and high-throughput sequencing. ResultsCompared with the wild-type rpoB gene （5 600 bp）， the amplified fragment of the rpoB knockout strain is 2 200 bp， which proved that the ΔrpoB attB：：rpoB conditional knockout strain of M. smegmatis is successfully constructed. The success rate of plasmid replacement is 100%. There were 540 kinds of single amino acid mutations in both E. coli library and M. smegmatis library， 5 301 kinds of multi-point mutations in E. coli library， and 853 kinds of multi-point mutations in M. smegmatis library. The correlation coefficient between E. coli library and M. smegmatis library is 0.84. ConclusionsWe have developed a strategy to construct a library of mutants targeting the essential mycobacterial gene rpoB， and successfully established a mutant library of rifampicin resistance gene rpoB.
ABSTRACT
Allyl alcohol is an intermediate widely used in industrial production activities, which has caused many occupational damage in China. In this paper, the data of a case of skin damage and clinical cure of inhalation pneumonia caused by occupational allyl alcohol exposure were analyzed and summarized. The patient accidentally inhaled large amounts of allyl alcohol at work and had skin exposure, which was mainly manifested as aspiration pneumonia, respiratory failure, eye damage and skin bullae. After short-term hormone shock therapy, mechanical ventilation, infection prevention, local treatment and other comprehensive treatment, the patient was clinically cured. This case suggests that chemical pneumonia and respiratory failure may be caused by inhalation of allyl alcohol, and skin bullae may be caused by skin contact. Early treatment and hormone use should be emphasized.

Objective To study the characteristics of self-esteem and life position of children with mild intellectual disability and the effects of adaptive behavior on self-esteem and life position. Methods From November, 2019 to January, 2020, 162 children with mild intellectual disabilities in Shanghai were investigated and evaluated with Adaptive Behavior Assessment System-Second version (ABAS-Ⅱ), Rosenberg Self-esteem Scale (SES) and Life Position Scale (LPS). Structural equation model was used to explore the specific effects of adaptive behavior on self-esteem and life position. Results The score of SES was (23.52±5.49), which was slightly lower than the norm (28.75±4.86) (t = -12.140, P < 0.001). The score of LPS was (50.76±11.85). Structural equation model showed that conceptual skill in adaptive behavior negatively affected life position (B = -0.450, P < 0.05); social skill (B = 0.480, B = 0.331, P < 0.05) and practical skill (B = 0.490, B = 0.294, P < 0.05) positively affected both life position and self-esteem. Conclusion Self-esteem decreases in children with mild intellectual disability, and the life position reached the theoretical median level. Among adaptive behavior, both social skill and practical skill positively affect self-esteem and life position, while conceptual skill negatively affects life position.

ABSTRACT
Objective:To explore the characteristics and related factors of unmet needs of nursing care and service for adults with extremely severe and severe intellectual disabilities. Methods:A total of 127 547 adults with extremely severe and severe intellectual disabilities were sampled. Descriptive statistics and multiple response analysis were conducted, and a structural equation model of unmet needs of nursing care and received the services was developed. Results:A total of 26 038 adults with extremely severe and severe intellectual disabilities reported unmet needs of rehabilitation, including nursing care (52.50%), medicine (36.90%), assistive device (20.90%), functional training (19.70%) and surgery (0.80%) respectively. A total of 11 640 adults with extremely severe and severe intellectual disabilities reported received rehabilitation services, including nursing care (49.90%), medicine (36.80%), functional training (19.10%), assistive device (14.10%) and surgery (1.00%) respectively. The structural equation model showed that received nursing care service (main effect = 0.646) and received rehabilitation services (included nursing care) (main effect = 0.014), age (main effect = 0.031), household registration (main effect = 0.015) and educational level (main effect = -0.158) had effects on unmet needs of nursing care (P < 0.001). Conclusion:Adults with extremely severe and severe intellectual disabilities reported unmet needs mainly involved in field of nursing care, and their rehabilitation services mapped to their main needs. It proposed to develop rehabilitation services tailored to their rehabilitation experience, age, socioeconomic status, functional conditions and characteristic of unmet needs, to develop accessible services items and individualized nursing care programs, and to expand the nursing care service supply and coverage of nursing care.
ABSTRACT
Objective:To explore the characteristics and the influential factors of unmet needs and services development of rehabilitation for people with extremely severe hearing disability (PSHDs). Methods:A total of 90 052 PSHDs were included. Multiple response was used to analyze the characteristics of unmet needs and services of rehabilitation. The structural equation model of the received service and unmet needs of PSHDs was developed. Results:The reporting rate of unmet needs of rehabilitation for PSHDs, from high to low, were assistive devices (61.5%), nursing care (24.1%), medicine (23.4%), functional training (17.6%) and surgery (2.5%). The reporting rate of received service for PSHDs, from high to low, were assistive devices (58.3%), nursing care (24.4%), medicine (22.4%), functional training (22.0%) and surgery (2.2%). Structural Equation Model showed that the more services received, the more needs for cochlear implantation surgery and speech therapy (P < 0.001); the better family income situation, the more needs for cochlear implantation surgery (P < 0.001); and age factor had significant effects on the unmet needs of cochlear implantation surgery and speech therapy (P < 0.001). Conclusion:PSHDs reported unmet needs and received services mainly included assistive devices, nursing care, medicine and functional rehabilitation training. Those PSHDs who had received services would report more demand of unmet needs, supposed that improving the accessibility and coverage of services should be emphasized in the development of rehabilitation services. According to ICF model, on the basis of the characteristics of the unmet needs of PSHDs, it proposed to take measures to implement precise rehabilitation services to improve the quality of services.

ABSTRACT
OBJECTIVE To investigate the effect of phosphotyrosine interaction domain containing 1 (PID1, NYGGF4) onpromotion of IR and HCC, and explore its underlying mechanisms. METHODS Lentivirus were used to mediate the knockdown of PID1 in HFD induced IR mouse model as well as ob/ob mice. Intraperitoneal glucose and insulin tolerance were performed 4 weeks after lentivirus injection. Hydrodynamics-based transfection was applied to induce the liver specific overexpression of PID1. Flow cytometry was exerted to detect the proportion and function of immune cells.qRT-PCR and Western blot were used to detect the expression of downstream pathways of PID1. Liquid chromatography-mass spectrometry (LC-MS) and co-immunoprecipitation (Co-IP) were conducted to identify proteins interacting with PID1.Chromatin immunoprecipitation(ChIP)was operated to measure the modification of H3K4me3 of PID1 promoter.RESULTS PID1 restriction improved insulin resistance,hyperglycemia and fatty liver. Conversely, hepatic knockdown of PID1 attenuated liver xenografted tumor growth. Moreover,PID1 liver-specific protooncogenes via hydrodynamics-based transfection established a primary hepatocellular carcinoma mouse model,induced an immunosuppressive environment,with the reduction of CD3+,CD4+,CD8+T cells,retarded maturation of dendritic cells(DCs),pronounced differentiation of regulatory T cells(Tregs),and recruitment of MDSC.In addition,PID1 overexpression activated prolifer-ation related genes, promoted anti-inflammatory genes, suppressed pro-inflammatory genes, induced glycolysis and lipid metabolism genes to facilitate tumorigenesis in liver. Importantly, PID1 exerted its tumor-promoting function through binding to epidermal growth factor receptor(EGFR)and activation of downstream KRAS/ERK pathway.As such,PID1 exist trimethylation of histone H3 at lysine 4(H3K4me3) modification and IR up-regulated the expression of PID1 by activation the H3K4me3 modification. CONCLUSION PID1 is a new gene that exerts both liver cancer-promoting and insulin resistance inducing function.IR accelerates liver cancer development and progression partially dependent on the activation of PID1.

ABSTRACT
OBJECTIVE@#To investigate the effect of radiotherapy plus recombinant human endostatin (RH-endostatin) on esophageal cancer and its mechanism.@*METHODS@#A total of 50 nudemice were equally randomized into control group, radiotherapy group, and combined therapy group I, II, and III after inoculating with Eca109 cell suspension (1 × 10(7) cells/mL). On the day of grouping, control group and radiotherapy group were injected normal saline, while radiotherapy group and 3 combined therapy groups received radiotherapy; besides, combined therapy group I, II, and III was injected RH-endostatin of 2.5, 5, 10 mg/kg respectively. After 3-week therapy, the tumors of each group were collected and microvessel density and VEGF expression in tumors were determined. In vitro, Eca109 cells were divided into control group, radiotherapy group, and combined therapy group. Forty-eight hours after treatment, cell cycle distribution and apoptosis rate were detected, and the activity of VEGF signal paths was semiquantitatively analyzed.@*RESULTS@#Since the 6th day of treatment, the relative tumor proliferation rate of combined therapy group II was lower than radiotherapy group (P < 0.05) and ≤40% since the 15th day. Average microvessel density and EGFR expression in combined therapy group II were lower than radiotherapy group (P < 0.05). In vitro, the cell percentage in S and G2/M phase of combined therapy group cells was lower than that in radiotherapy group cells, while the apoptosis rate and the expression of VEGF, AKT, p-AKT, ERK1/2 and p-ERK1/2 in combined group were higher than that in radiotherapy group (P < 0.05).@*CONCLUSIONS@#RH-endostatin promotes the efficacy of radiotherapy on esophageal cancer, which may be partly realized by inhibiting the activity of VEGF related signal paths.
ABSTRACT
Autism is a developmental disease with unknown etiology, which will affect autistic children through all the life. Although some therapeutic method, such as the training of the eye contact ability, speech imitation, social games, etc., and even the integration of all above methods are effective for the treatment of autism, however, the communication problems frequently appear in the process of treat-ment, and the effect is weakened extremely. In order to promote the effect of rehabilitation, this article introduced the stroking theory and an-alyzes the basic characteristic of behavior for autistic children, then drew the stroking profile. The result showed that autism children often require and accept the positive stroking, and at the same time, they show a lot of negative stroking. The researcher provided a series of effec-tive advice on stroking for medical staff and parents in respond to the autistic children.
ABSTRACT
@#Because the rehabilitation process is too long and its effect is non-significant, stroke patients are prone to showing over-reliance on their families, being unconfident in their abilities, and they usually miscommunicate with medical staff, in fact, the reason why they have these problems is that they didn't manifest appropriate ego states, so they couldn't communicate with families and medical staff healthily,which is extremely unfavorable for stroke rehabilitation. So-called ego state is individual mentality and corresponding behavior patterns.This paper used ego state concept in transactional analysis theory to describe the change of stroke patients' ego states, and analyze the communication patterns among patients, medical staffs and families, in order to assist patients to be aware of their own ego states, and present them properly, develop healthy communication, and promote the rehabilitation of the disease in the end.
ABSTRACT
Injunction is a conception of transactional analysis. It is an injunctive message delivered from parent to children. Injunction is important for development of personality. We suppose that a person who received more injunctions may tend to have more psychological problems. If chronic disease patients have some injunctions, they may show some psychological characteristics which are not conductive for rehabilitation. This article analyzed the injunctions in chronic disease patients and some coping methods were also dicussed.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the role of store-operated calcium channels (SOCs) in primary hepatocytes under conditions of calcium overload and ethanol-induced injury.</p><p><b>METHODS</b>The in vitro model of chronic ethanol-induced hepatocyte injury was established using primary hepatocytes isolated from Sprague-Dawley rats. Ethanol-induced changes (24, 48 and 72 h; 50, 100, 200, 400 and 800 mmol/L) in expression of the SOCs proteins stromal interaction molecule 1 (STIM1) and calcium release-activated calcium channel protein 1 (Oria1) were detected by qualitative PCR analysis (mRNA) and western blotting (protein). The possible role of these two SOCs proteins in the ethanol-induced extracellular calcium influx and related liver cell injury was determined by treating the cell system with various channel blockers (EGTA, La3+, and 2-APB). Cell viability was determined by MTT assay and cytosolic free calcium ion concentration was determined by flow cytometry.</p><p><b>RESULTS</b>After 24 h of exposure to 0 (untreated) to 800 mM/L ethanol, the cell viability was reduced in a concentration-dependent manner. The 400 mmol/L concentration of ethanol decreased cell viability by 57.34% +/- 2.34%. and was chosen for use in subsequent experiments. Compared with the untreated control cells, the ethanol-treated cells showed significantly up-regulated mRNA and protein expression of both STIM1 and Orai1 at all times examined, suggesting that the ethanol-stimulated expression of STIM1 and Orai1 could persist for at least 72 h. The ethanol treatment induced increase in cytoplasmic calcium levels was significantly (and similarly) reduced by co-treatment with any of the three channel blockers.</p><p><b>CONCLUSION</b>Chronic ethanol exposure can increase the expression of STIM1 and Orai1 in primary liver cells, suggesting that ethanol may increase extracellular calcium influx by up-regulating expression of these SOCs protein molecules, ultimately aggravating liver cell damage.</p>

<p><b>OBJECTIVE</b>To investigate the clinical significance of dynamic changes of blood urea nitrogen (BUN), serum creatinine (Cr), serum cystatin (Cys C) and urinary protein on renal injury with paraquat poisoning.</p><p><b>METHODS</b>According to the clinical manifestation and curative effect, the clinical information was analyzed retrospectively in 35 cases of acute paraquat poisoning, survival after eight weeks as the standard. Poisoning patients were taken a fasting blood 5 ml and the middle of urinary on the 1st day, 3rd day, 7th day, 14th day, 21st day and 8 weeks after the poisoning. Then the levels of serum BUN, Cr, Cys C and urinary protein were detected by automatic biochemistry analyzer. 30 cases healthy subjects were randomly selected as normal control group, and discharged kidney disease and other diseases of urinary system history. The same laboratory subjects have been done.</p><p><b>RESULTS</b>The level of serum Bun, Cr, Cys C of survival group increased significantly compared with control group within 21 days (P < 0.05). The level of serum BUN, Cr Cys C decreased on the 14th day. The decreased level of serum Cys C was lower than that of serum BUN and Cr. The renal function of 29 cases among 35 cases survival patients recovered on 21st day. The renal function of 31 cases among 35 cases survival patients recovered 8 weeks late. The positive rate of urinary protein of survival patients was high in the early intoxication (76.9%).</p><p><b>CONCLUSION</b>Serum Cys C is sensitive indicator to reveal the kidney injury on paraquat poisoning patients and have higher value of clinical applications in the diagnosis of the kidney injury of paraquat poisoning, which sensitivity is higher than serum BUN and Cr. The kidney injury caused by paraquat poisoning is reversible.</p>

@#Due to the influence of potential psychological trauma, athletes in the competition may repetitively suffer poor performances, such as losing his usual form, slump, choking, and so on. These under-performing problems actually are symptoms of sports post-traumatic stress disorder (SPTSD). SPTSD refers to the pathological physical and mental after-effects of a trauma previously suffered by the athlete on that athlete's subsequent performances. This is a very common physical and emotional problem in athletics that impairs athletes' performance, affecting their competition results. By peak performance eye movement desensitization and reprocessing therapy, therapists can deal with this problem effectively and help athletes eliminate symptoms of sports post-traumatic stress disorder, improving the competition performance.
