Alternative splicing of pre-messenger RNA (pre-mRNA) is a crucial mechanism for the diversity of the human transcriptome and proteome. Alternative splicing is a complex gene regulation process. Whole-transcriptome analysis shows that 95% of human exonic genes are alternatively spliced, involving various cis-acting elements and trans-acting factors. Any changes in any component or step may cause erroneous splicing events and lead to the occurrence of various related diseases. In addition to gene replacement therapy that directly changes the splicing results, RNA splicing modification is expected to become a new therapeutic strategy to alleviate or treat diseases by targeting and correcting abnormal pre-mRNA splicing. Splicing modification tools currently developed including RNA trans-splicing, antisense oligonucleotides, small interfering RNA, and small molecule drugs can correct abnormal splicing through different ways. This article reviews the resent progress of epigenetic regulation of pre-mRNA alternative splicing in recent years, and discusses the occurrence and regulation of alternative splicing, the types of diseases caused by related splicing defects, and the current-used tools for targeting and altering splicing. The importance of splicing modification strategies in the future treatment of human diseases is envisioned.

Objective To investigate the influence of Xiyanping injections therapy on inflammation factors and lung function for old patients with acute exacerbation chronic obstructive pulmonary disease (AECOPD).Methods Ninety-two patients with AECOPD were randomly divided into the control group (n =46) and observation group(n =46).Patients in control group were given conventional treatment,in observation group were given XiYanPing injections for 2 weeks treatment on the basis of treatment of control group.The C-reactive protein(CRP),blood sedimentation rate (ESR),interleukin 10 (IL-10),1 s forced expiratory volume (FEV1),forced vital capacity (FVC),FEV1/FVC change and clinical effect of the two groups were recorded.Results There was no statistically significant difference in terms of CRP,ESR and IL-10 between the two groups before treatment (P ＞ 0.05).After treatment,CRP and ESR in control group were reduced from (35.6 ±9.8) mg/L and (56.2 ± 16.4) mm/h to (14.2 ± 8.1) mg/L and (22.4 ± 11.6) mm/1 h and the difference was significant (t =-14.515,-12.008;P ＜ 0.05),while in observation group decreased from (36.4 ± 8.2) mg/L,(54.6 ± 15.4) to (8.2 ± 6.2) mg/L,(16.8 ± 9.6) mm/h and the difference was significant (t =-18.468,-15.249;P ＜ 0.05).Meanwhile,the level of IL-10 in the two groups significantly increased and the observation group showed more.IL-10 in control group increased from (168.8 ± 62.4) ng/L to (212.4 ± 85.6) ng/L and the difference was significant(t =5.468,P ＜ 0.05),and in observation group increased from (172.8 ± 65.1) ng/L to (266.4 ± 92.6) ng/L and the difference was significant (t =6.368,P ＜ 0.05).The FEV1 and FVC were markedly increased after treatment and the observation group showed increase more.FEV1and FVC in control group were increased from (1.41 ±0.15) L and (2.62 ±0.88) L to (1.62 ± 0.18) L and (2.89 ± 0.92) L,and the differences were significant (t =2.186,2.415 ; P ＜ 0.05).While in observation group,FEV1 and FVC were increased from (1.42 ± 0.16) L and (2.59 ± 0.84) L to (1.84 ±0.21) L and (3.12 ± 0.94) L,and the differences were significant (t =4.366,4.585 ; P ＜ 0.05).Total efficacy of observation group was 91.3％ (42/46),obviously higher than that of control group(78.3％ (36/46) ; x2 =4.658 ;P ＜ 0.05).Conclusion Xiyanping injections can reduce the inflammatory response in patients with AECOPD,improve lung function and the effect of treatment.

Objective:To evaluate the security, efficacy and side effects of E_2 transdermal patch (Fem-7) in the treatment of menopausal syndrome. Methods:A total of 60 cases with menopausal syndrome (blood serum FSH >30 U/L,E_2 <109.8 pmol/L) were randomly divided into treatment group ( Fem-7 group) and control group (estrodiol valerate (E_2V) group) for 12 weeks treatment. Fem-7 group changed patch every 7 days and took the 2 mg medroxyprogesterone (MPA) every day. While the E_2V group took the 2 mg MPA and 1.5 mg E_2 V every day. Serum E_2, FSH, lipoprotein and coagulation function were evaluated at baseline and at the 12th week of the treatment. In addition, menopausal symptoms and some other index of security and side effects were also observed. Results:Kupperman indix in both groups was decreased and the mean value of E_2 was increased obviously. Hepatic function, renal function, coagulation function and blood glucose were no obvious change. Lipoproteina was descended markedly in Fem-7 group. Other index of security in both groups was no obvious change. Conclusions:Fem-7 patch is secure and valid for relieving symptom of menopause, especially for the women who is not sutable for oral medication.

Objective: To explore the high dose atorvastatin reducing contrast induced nephropathy (CIN) rate in patiens with emergent percutaneous coronary intervention (PCI) via improveing heat shock protein-90 (HSP90) expression with its possible mechanism. Methods: A total of 158 STEMI patients with emergent PCI in our hospital were studied. The patients were randomly divided into 2 groups: High dose atorvastatin group, the patients received pre-operative atorvastatin 40 mg,n=80 and Control group, the patients received pre-operative placebo,n=78. The serum creatinin (Scr), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), superoxide dismutase (SOD), malondialdehyde (MDA), nitrogen monoxide (NO), HSP90 mRNA expression and protein concentration and urine α1-microglobulin were examined in all patients and the incidence rates of CIN were compared between 2 groups. Results: Compared with Control group, High dose atorvastatin group had drcreased Scr (68.92 ± 8.80) μmol/L vs (77.25 ± 13.36) μmol/L, MDA (3.88 ± 0.53) nmol/L vs (4.08 ± 0.52) nmol/L and urine α1-micrglobulin (1.38 ± 0.36) mg/dl vs (1.89 ± 1.13 ) mg/dl; increased Ccr (89.71 ± 9.85) ml/min vs (77.28 ± 13.78) ml/ min, SOD (129.52 ± 30.63) U/ml vs (117.66 ± 27.98) U/ml, NO (66.23 ± 29.26) μmol?gprot vs (55.12±27.43) μmol?gprot, allP<0.05. Compared with Control group, High dose atorvastatin group presented higher post-operative HSP90 mRNA expression (0.466 ± 0.158) vs (0.224 ± 0.278 ) and protein concentration (1259.83 ± 121.17) pg/ml vs (1195.0 ± 127.65) pg/ml, allP<0.05. The incidence rate of CIN was lower in High dose atorvastatin group (2.5%) than Control group (10.3%),P<0.05. Conclusion: A high dose atorvastatin administration before emergent PCI may decrease CIN occurrence rate. Atorvastatin may promote HSP90 expression, increase NO produciton, then improve the vascular endothelial function and anti-oxidative ability to protect the renal function in STEMI patients.
