The cGAS-STING pathway plays a significant role in host defense against viral and bacterial infection.In the process,the cytoplasmic free DNA,considered as a danger signal,is recognized by nucleotidyl transferase cGAS.cGAS is activated by double-stranded DNA (dsDNA) and catalyzes the synthesis of a noncanonical cyclic dinucleotide 2'5'-cGAMP from adenosine triphosphate (ATP) and guanosine triphosphate (GTP).cGAMP serve as an endogenous second messenger to stimulate the induction of type Ⅰ interferons via STING.In addition to the exogenous bacterial or viral DNA,abnormal deposition of host DNA in cytosol also activates the cGAS-STING signaling pathway cascade,resulting in inflammation and autoimmune diseases.Subsequent studies found that this pathway also plays an important role in tumor's responsiveness to radio-therapy and chemo-therapy.Activation of cGAS-STING pathway produces or enhances the therapeutic efficacy.These findings suggest that specifically interfering with cGAS-STING activation may hold therapeutic value for the treatment of cancer,infection and inflammatory diseases.In this paper,the activation mechanism of cGAS-STING pathway and its relationship with the treatment of diseases were summarized,and the regulation of cGAS-STING pathway was introduced in detail.

Objective To investigate the relationship between the preterm infants after premature rupture of the membranes(PROM)brain injury and some cellular factors in the umbilical cord blood and amniotic fluid,and ana-lyze the biological markers with great predictive value,and provide a theoretical basis for early monitoring of brain injury in premature infants. Methods One hundred and thirty - nine singleton infants with PROM,their gestation less than 34 weeks,were evaluated. The umbilical cord blood and amniotic fluid of cytokines,including interleukin - 1β(IL - 1β),IL - 4,IL - 6,IL - 8,IL - 10,IL - 17A,tumor necrosis factor alpha(TNF - α),granulocyte colony - stimu-lating factor(G - CSF),monocyte chemotactic protein - 1(MCP - 1),S100B protein and soluble intercellular adhe-sion molecule - 1(sICAM - 1)levels were measured with Luminex liquid chip. All the premature infants underwent brain imaging for the diagnosis of brain damage. All cases were divided into brain injury group and non - brain injury group based on brain imaging examination. Results The concentration of IL - 10 in cord blood was significantly lower in the brain injury group than that in the non - brain injury group,and the difference was statistically significant(P ﹤0. 05). The levels of IL - 1β,IL - 6,IL - 8,TNF - α,G - CSF,MCP - 1,S100B and sICAM - 1 in the brain injury group were significantly higher than those of non - brain injury group,and the differences were statistically significant (all P ﹤ 0. 05). The levels of IL - 1β,IL - 6,IL - 8,TNF - α,G - CSF,MCP - 1 and sICAM - 1 in the amniotic fluid were significantly higher than those of non - brain injury group,and the differences were statistically significant(all P ﹤ 0. 05),but amniotic fluid S100B protein level was similar between 2 groups,which had no statistical significance (P ﹥ 0. 05). To predict the value of brain damage in premature infants,the highest sensitivity in cord blood was S100B protein,the highest specificity was IL - 6. The highest sensitivity in amniotic fluid was IL - 1β,and the highest specificity was IL - 8. The levels of IL - 4 and IL - 17A in the umbilical cord blood and amniotic fluid,IL - 10 in amniotic fluid were very low,and had no predictive value for brain damage. Conclusions Many biological markers in umbilical cord blood and amniotic fluid provide information about the risk of brain injury in premature infants. The highest sensitivity in cord blood was S100B protein,the highest specificity was IL - 6. The highest sensitivity in amniotic fluid was IL - 1β,the highest specificity was IL - 8. Changes in inflammation - related biomarkers suggest that brain damage in the preterm infants might be associated with intrauterine inflammation.

OBJECTIVETo explore the clinical effects of one-stage hemiarthroplasty in treating fresh subtrochanteric fracture combined with old femoral neck fracture.

METHODSFrom October 2003 to October 2013, 7 patients with fresh subtrochanteric fracture and old femoral neck fracture were treated with hemiarthroplasty in one stage. There were 5 males and 2 females, aged from 69 to 80 years old with an average of 74.5 years. According to the Garden classification, 2 cases were type IV and 5 cases were type V. According to the A0 classification of subtrochanteric fracture, all cases were type A1 (long oblique femoral subtrochanteric fractures). Biological coating long handle femoral prosthesis was used in the patients. The hip joint functions were assessed according to Charnley scoring system after all hemiarthroplasty.

RESULTSSeven patients were followed up from 12 to 24 months with an average of 18 months. There were 1 case with urinary system infection and 1 case with deep venous thrombosis. Of all, 5 cases recovered the walk ability at 6 months after operation and 2 cases could walk with the help of the crutch at 1 year after operation. According to Charnley scoring system to assess the hip joint function, the total Charnley scores reached 15.0±2.5, and 4 cases got an excellent results, 2 good, 1 fair.

CONCLUSIONArthroplasty through anterolateral approach can obtain satisfactory clinical effects in treating fresh subtrochanteric fracture combined with old femoral neck fracture, it has advantages of good joint stability, little pain, less complication, quickly recover, early activities on fields.

BACKGROUND: Some researches suggest that improvement of motor function is closely related to cognitive function. The better the cognitive status is, the better the recovery of motor function is. Early evaluation of cognitive function can predict prognosis of motor function and improve generalized ability, social communication abilities and quality of life (QOL).OBJECTIVE: To observe the correlation of cognitive function in hemiplegia and aphasia and analyze the prognostic factor of early cognitive dysfunction in patients with acute stroke.DESIGN: Contrast study.SETTING: Department of Neurology, Taian Central Hospital; Department of Neurology, Affiliated Hospital of Medical College of Qingdao University.PARTICIPANTS: Fifty patients with acute stroke were enrolled from Neurological Department of Taian Central Hospital and Neurological Department of the Affiliated Hospital of Medical College of Qingdao University from January 2002 to May 2005. They were 32 males and 18 females aged 34-78 years. All patients were coincidence with the Diagnostic Criteria of Acute Stroke established by the Fourth National Cerebrovascular Diseases Meeting and diagnosed with CT or MRI. Patients were told about the evaluation in details. Among them, 44 patients had hemiplegia, including 30 males and 14 females aged 34-78 years; 30 had aphasia, including 17 males and 13 females aged 34-78 years; 20 had non-aphasia, including 14 males and 6 females aged 38-70 years.METHODS: ① Aphasia was tested with Western Aphasia Battery (WAB).Aphasic quotient of ＜ 93.8 was regarded as aphasia; otherwise, it was regarded as non-aphasia. ② Motor function was evaluated with Fugl-Meyer (FMA).Motor function of upper and lower limbs was scored as 100 in total. The higher the points were, the better the motor function was. ③ Cognitive function was evaluated with Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), which contained 4 items (orientation, perceptibility, visual-motor organization and thinking ability) and 22 subtests in total. The higher the points were, the better the cognitive function was. Functional evaluation started at half-month treatment onset. Intergroup comparison of their mean value was tested using Student's test and one-way analysis of variance.MAIN OUTCOME MEASURES: ① Correlation between cognitive function and hemiplegia; ② correlation between cognitive function and aphasia.RESULTS: Fifty patients with acute stroke were all involved in the final analysis. ① Correlation between cognitive function and hemiplegia: Scores of orientation, perception, visual-motor organization and cognitive function of 44 patients with hemiplegia were positive positively correlated with FMA scores of motor function (r=0.534, 0.598, 0.500, 0.548, P ＜ 0.01); however,scores of thinking ability was not correlated with FMA scores of motor function (r=0.310, P ＞ 0.05). ② Correlation between cognitive function and aphasia: Scores of orientation, perception, visual-motor organization, thinking operation and cognitive function of patients with aphasia were (4.60±2.37), (15.10±6.02), (14.00±6.93), (12.33±6.77), (1.83±1.09) points,which were lower than those of patients with non-aphasia (7.30±1.08),(23.20±1.11), (24.25±4.08), (24.20±5.43), (3.50±0.76) points (t=5.44 to7.197, P ＜ 0.05).CONCLUSION: The more severe the cognitive dysfunction is, the more severe the hemiplegia is. Cognitive function in stroke patients with aphasia is significantly reduced.

Objective: To observe the inhibitory effect of scopolamine(Spm) and chlopromazine (Clo) on withdrawal syndromes in morphine dependent rats. Methods: The intensity of withdrawal syndromes on the model of morphine dependent rats was recorded after single or muiltiple subcutaneous administration(sc) of Spm and Clo at different doses. Results: Withdrawal syndromes were markedly decreased when single Spm 1 mg/kg and Clo 0.5 mg/kg combined with morphine were injected (P<0.05). Spm+Clo(sc) had much stronger effects on inhibiting withdrawal syndromes after intraperitoneal (ip) naloxone in morphine dependent rats (P<0.01). Conclusion: Spm can act on Ach-receptor and relieve morphine withdrawal syndromes. Clo may have a synergistic action with Spm via α2-receptor in the locus coeruleus of the rat brain stem.

To explore the major risk factors for hepatitis B (HBV) in Shanghai Jinshan district.A one-to-two matched case control study was performed among the residents of Shanghai Jinshan district in 2010.The data were analyzed by single factor and multivariate analysis performed with SAS 9.13.Single factor analysis showed that the risk factors for hepatitis B were family member with hepatitis B,no vaccination history of hepatitis B virus vaccine and oral treatment.Muhivariable analysis showed that family member with hepatitis B (OR =1.91),no vaccination history of HBV vaccine (OR =0.49) and oral treatment (OR =2.06) were independent risk factors for HBV infection in Shanghai Jinshan district.Strengthening health education for HBV prevention,modifying unhealthy living habits and standardizing the treatment of oral diseases are important measures for lowering infectious rate of HBV.

Objective To improve the understanding of autoimmune disease related panereatitis by analyzing their clinical features.Methods The clinical features were analyzed retrospectively in 28 autoimmune disease related pancreatitis cases from Peking Union Medical College Hospital(PUMCH),according to the associated autoimmune diseases.Results (1)The average age was(40.0±16.1)years,and the ratio of male to female patients Was 1:6.There were 24 acute and 4 chronic pancreatitis in the 28 cases.(2)The common related autoimmune diseases were systemic lupus erythematosus(20/28)and Sjogren's syndrome(6/28).(3)The characteristics of the autoimmune diseases was multi-system involvement,such as hematologic system,kidney,liver,etc.(4)Clinical features of those acute pancreatitis shown that no distinct trigger exist for acute pancreatitis.and the radiological changing Was not prominent.(5)In laboratory examination,an obvious increase of CA199 coaid be seen,paralleling the severity of pancreatitis.(6)Glucocorticoids or immunosuppressors was effective,and the mortality rate of acute pancreatitis cases was 33.3%.ConclusionsAutoimmune disease related pancreatitis is dominant with acute pancreatitis and females is common,which may reflect the activity of autoimmune diseases.Autoimmune disease related acute pancreatitis has a high mortality rate.Glucocorticoids and/or immunosuppressors may be useful to relieve the pancreatitis.
