ABSTRACT
As a ligand-dependent transcription factor,retinoid-associated orphan receptor γt(RORyt)that controls T helper(Th)17 cell differentiation and interleukin(IL)-17 expression plays a critical role in the pro-gression of several inflammatory and autoimmune conditions.An emerging novel approach to the therapy of these diseases thus involves controlling the transcriptional capacity of RORyt to decrease Th17 cell development and IL-17 production.Several RORyt inhibitors including both antagonists and inverse agonists have been discovered to regulate the transcriptional activity of RORyt by binding to orthosteric-or allosteric-binding sites in the ligand-binding domain.Some of small-molecule inhibitors have entered clinical evaluations.Therefore,in current review,the role of RORyt in Th17 regulation and Th17-related inflammatory and autoimmune diseases was highlighted.Notably,the recently developed RORyt inhibitors were summarized,with an emphasis on their optimization from lead compounds,ef-ficacy,toxicity,mechanisms of action,and clinical trials.The limitations of current development in this area were also discussed to facilitate future research.
ABSTRACT
Objective:To study the clinical and genetic features of neonatal Smith-Kingsmore syndrome (SKS).Methods:The clinical data of a newborn with SKS admitted to our hospital in November 2021 were reviewed. Using "Smith-Kingsmore", "rapamycin gene", "newborn", "premature infant", "the mammalian target of rapamycin", "MTOR", "mTOR", "Smith-Kingsmore syndrome", "megalencephaly", "macrocephaly" and "hemimegalencephaly" as keywords, databases including CNKI, Wanfang Database, VIP database, PubMed, Embase, Web of Science and the Cochrane Library were searched from the date of establishment to January 1, 2022. The clinical and genetic features of neonatal SKS from published literature were summarized.Results:The case admitted to our hospital was a male preterm infant. The presenting symptoms were groan and hypotonia. The facial abnormalities included macrocrania, ocular hypertelorism, depressed nasal bridge and low-set ears. Brain MRI showed lateral ventricle enlargement. Whole-genome sequencing (WGS) showed mTOR gene nonsense heterozygous mutation (NM_004958.4:c.7255G>A:p.Glu2419Lys). Neither father nor mother had any pathogenic gene mutations. The infant had seizure at 2-month and phenobarbital was effective reducing seizure. Gross motor delay was present at 3-month. Sixteen related articles were retrieved, including eight articles with 10 neonatal cases. Among them, 6 cases were male. The main clinical features were megalencephaly or hemimegalencephaly (9/10), facial developmental malformation (8/10), hypotonia (6/10), large-for-gestational age (LGA) infants (5/10), cerebral ventricle dilation (4/10) and abnormal corpus callosum (4/10). All the gene mutations were missense mutations, including c.5395G>A(p.Glu1799Lys) mutation in 5 cases, c.4448G>T(p.Cys1483Phe) mutation in 1 case, c.4448G>T(p.Cys1483Tyr) mutation in 1 case, c.7235A>T(p.Asp2412Val) mutation in 1 case, c.5663T>G(p.Phe1888Cys) mutation in 1 case, c.5390C>T(p.Thr1799IIe) mutation in 1 case.Conclusions:The clinical phenotypes of neonatal SKS are diverse, including megalencephaly, facial malformation, LGA and hypotonia. The brain MR findings included (hemi) megalencephaly, cerebral ventricle dilation and corpus callosum hypoplasia. Most of the gene mutations are missense mutations and c.5395G>A(p.Glu1799Lys) is the hotspot.
ABSTRACT
Objective:To investigate the influencing factors of anastomotic leakage after laparoscopic intersphincter resection (ISR) for extremely low rectal cancer and construction of nomogram prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 812 patients who underwent laparoscopic ISR for extremely low rectal cancer in the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) from February 2012 to February 2022 were collected. There were 459 males and 353 females, aged (51±11)years. Observation indicators: (1) surgical situations; (2) follow-up; (3) influencing factors of postoperative anastomotic leakage; (4) construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. The COX proportional hazard model was used for univariate and multivariate analyses. The R software(3.5.1 version) was used to construct nomogram prediction model. The receiver operating characteristic (ROC) curve was drawn and the area under curve (AUC) was used to evaluate the efficacy of the nomogram prediction model. The Bootstrap method was used for internal verification and to calculate the average consistency index (C-index). Results:(1) Surgical situations. All 812 patients underwent laparoscopic ISR for extremely low rectal cancer, including 388 cases undergoing partial ISR, 218 cases undergoing subtotal ISR and 206 cases undergoing complete ISR. All 812 patients underwent ileal protective ostomy, and there were 306 cases with double anastomosis and 203 cases with left colic artery preserved, respectively. The operation time and volume of intraoperative blood loss of 812 patients was (179±33)minutes and (33±13)mL, respectively. (2) Follow-up. All 812 patients were followed up for (13.5±0.9)months. Of the 812 patients, there were 62 cases with postoperative anastomotic leakage and the healing time of these cases was (33±6)days. (3) Influencing factors of postoperative anastomotic leakage. Results of multivariate analysis showed that male, neoadjuvant chemoradiotherapy, failure of reser-ving left colic artery were independent risk factors of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer ( hazard ratio=5.98, 4.00, 16.26, 95% confidence interval as 1.66-24.12, 1.30-12.42, 3.00-90.89, P<0.05). (4) Construction and evaluation of nomogram prediction model for postoperative anastomotic leakage. According to the results of multivariate analysis, male, neoadju-vant chemoradiotherapy and failure of reserving left colic artery were used to construct the nomogram prediction model for anastomotic leakage after laparoscopic ISR for extremely low rectal cancer, and the score of these indexes in the nomogram prediction model was 50, 49, 93, respectively. The total score of these index corresponded to the incidence rate of anastomotic leakage. Results of ROC curve showed that the AUC of nomogram prediction model of anastomotic leakage after laparoscopic ISR for extremely low rectal cancer was 0.87 (95% confidence interval as 0.80-0.93, P<0.05), with sensi-tivity and specificity 0.96 and 0.60, respectively. Results of internal verification showed that the C-index of nomogram prediction model was 0.87. Conclusion:Male, neoadjuvant chemoradiotherapy, failure of reserving left colic artery are independent risk factors of anastomotic leakage after laparo-scopic ISR for extremely low rectal cancer, and the nomogram prediction model based on these indexes can predict the incidence rate of postoperative anastomotic leakage.
ABSTRACT
Patients with abdominal surgery history always present different degrees of abdominal adhesion. In the past, it was regarded as a relative contraindication of laparoscopic surgery. With the development of minimally invasive concept, reoperative minimally invasive surgery is proposed in clinic to avoid huge trauma caused by multiple open surgeries. In June 2022, a laparoscopic assisted ileostomy reduction was performed for a patient with history of multiple abdominal injuries in Shanghai Changzheng Hospital. Minimally invasive achieved after huge trauma, and it maximized the benefit to the patient.
ABSTRACT
Objective:To investigate the efficacy and safety of dienogest (DNG) alone and gonadotropin-releasing hormone agonist (GnRH-a) combined with DNG sequential treatment to adenomyosis.Methods:The clinical data of 110 patients with adenomyosis attending the First Affiliated Hospital of Nanjing Medical University from December 2019 to March 2022 were retrospectively analyzed, including 40 patients treated with DNG (2 mg/day) alone (DNG group) and 70 patients treated with sequential DNG (2 mg/day) after 3-6 injections of GnRH-a (GnRH-a+DNG group). The clinical data before and after treatment were compared between the two groups.Results:(1) The dysmenorrhea visual analogue scale (VAS) scores, cancer antigen 125 (CA 125) and cancer antigen 19-9 (CA 19-9) levels at different time periods after treatment were significantly lower than before treatment in both groups (median before treatment: DNG group 70.0 mm, 68.55 kU/L, 22.45 kU/L respectively, GnRH-a+DNG group 80.0 mm, 151.50 kU/L, 20.44 kU/L respectively; all P<0.001). (2) The hemoglobin (Hb) levels of patients in both groups at different time periods after treatment were significantly higher than those before treatment (median: DNG group 102.00 g/L, GnRH-a+DNG group 94.00 g/L; all P<0.001). (3) Treatment with DNG alone did not have a significant effect on uterine volume in patients of DNG group ( P>0.05), and uterine volume decreased significantly in the 15th-24th months of GnRH-a+DNG group compared with that before treatment (median: 167.76 vs 227.77 cm 3; P<0.05). (4) There were no significant differences in hepatic and renal function and coagulation indexes between the two groups before and after treatment (all P>0.05), and no significant abnormal lesions were observed in breast tissue during the follow-up period. (5) The incidence of amenorrhea of GnRH-a+DNG group was higher than that of DNG group, and the incidences of irregular spotting bleeding and breakthrough hemorrhage were lower than those in DNG group. Conclusions:Whether DNG is used alone or in combination with GnRH-a in sequence, it could significantly relieve dysmenorrhea symptoms, improve the level of Hb, reduce the levels of CA 125 and CA 19-9 in patients with adenomyosis, with no adverse effects on coagulation and hepatic or renal function. GnRH-a sequential DNG therapy is superior to DNG alone in improving uterine bleeding patterns and controlling the growth of uterine volume in patients with adenomyosis.
ABSTRACT
Objective:To evaluate the barrier-free level of village clinics of a city in the aging era, for references in improving the barrier-free medical environment for the elderlies.Methods:The village dectors of 156 village clinics in 12 counties of a city were selected as the objects of a questionnaire survey from Dec.2020 to Jan.2021, with 6 evaluation indexes established, each set with 1-10 points. This questionnaires was used to survey the barrier-free construction levels of village clinics. The data were statistically analyzed by rank sum ratio and quadrant graph model.Results:The barrier-free buildings of such clinics scored 32.86 points in average. Among the six indexes, the barrier-free access and doors(7.21 points) scored the highest, and the barrier-free parking space(4.71points) and toilets(3.28 points) scored the lowest. All the counties of the city fell into four categories, including 2 counties with high degree of aging-high level of accessibility, 4 counties with low degree of aging-high level of accessibility, 4 counties with low degree of aging-low level of accessibility, and 2 counties with high degree of aging-low level of accessibility, according to the quadrant graph model built based on the aging degrees and the barrier-free levels of village clinics.Conclusions:The barrier-free level of the village clinics in a city needs to be further improved, and the barrier-free transformation of parking space and toilets should also be strengthened in the future. The government should take different measures in view of conditions of each county to improve the accessibility of village clinics and facilitate the health care-seeking of elderlies.
ABSTRACT
Objective:To explore the different coagulation state in patients with adenomyosis and its clinical significance.Methods:Clinical data of the patients admitted to the First Affiliated Hospital of Nanjing Medical University from January 2017 to December 2021 were retrospectively analyzed. (1) Differential coagulation state between 25 healthy women and 25 patients with adenomyosis were compared during menstrual and non-menstrual periods. (2) The coagulation indexes of 145 patients with adenomyosis (observation group 1) and 129 patients with cervical intraepithelial neoplasia grade Ⅲ (control group 1) who underwent hysterectomy in non-menstrual period were compared. (3) The coagulation indexes of 154 patients with adenomyosis (observation group 2) and 147 women without myometrial lesions (control group 2) who underwent endometrial curettage during uterine bleeding period were compared. (4) Correlations of coagulation index with cancer antigen 125 (CA 125), cancer antigen 19-9 (CA 19-9) and uterine volume in patients with adenomyosis were analyzed. Results:(1) The coagulation state of each health women during the menstrual and non-menstrual period showed no significant differences (all P>0.05). For the 25 patients with adenomyosis, fibrinogen [FIB; 2.61 g/L(2.50-3.10 g/L)] and D-dimer [0.60 mg/L (0.40-1.00 mg/L)] in the menstrual period were significantly higher than those in the non-menstrual period [2.25 g/L (1.90-2.70 g/L) and 0.27 mg/L (0.20-0.40 mg/L), respectively; both P<0.01], while thrombin time [TT; 16.70 s (16.10-17.40 s)] in the menstrual period was significantly lower than that in the non-menstrual period [17.95 s (17.20-18.40 s); P<0.01]. (2) In the non-bleeding period, D-dimer [0.26 mg/L (0.20-0.40 mg/L)] and platelet count [257.0×10 9/L (212.0×10 9/L-308.5×10 9/L)] of observation group 1 were significantly higher than those of control group 1 (all P<0.01). Besides, FIB ( r=0.237, P=0.004) and D-dimer ( r=0.373, P<0.001) were positively correlated with CA 125, while prothrombin time (PT; r=-0.208, P=0.012) and internationalized normalized ratio of plasma prothrombin time (PT-INR; r=-0.201, P=0.015) were negatively correlated with CA 19-9. (3) In the bleeding period, PT [10.70 s (10.10-11.20 s)] and PT-INR [0.93 (0.90-1.00)] of observation group 2 were significantly lower than those of control group 2 (all P<0.01), while D-dimer [0.41 mg/L (0.20-0.80 mg/L)] was significantly higher than that in the control group 2 ( P<0.001). Furthermore, FIB ( r=0.252, P=0.038) and D-dimer ( r=0.321, P=0.008) were positively correlated with uterine volume, while activated partial thromboplastin time (APTT; r=-0.190, P=0.018) and TT ( r=-0.304, P=0.012) were negatively correlated with uterine volume. (4) During non-menstrual period and uterine bleeding period, APTT and TT in patients of observation group 1 and 2 combined with anemia were significantly lower than those of non-anemia patients (all P<0.05). Conclusion:Patients with adenomyosis have a tendency to hypercoagulability in both the uterine bleeding and non-bleeding periods, which may be related to enlarged uterine volume, increased serum CA 125 and anemia.
ABSTRACT
Objective:To analyze the psychological contract satisfaction of contracted residents and its impact on their behavioral intentions under the guidance of incomplete contract theory, for reference in improving the effectiveness of contracted family doctor services.Methods:1 100 contracted residents from nine townships/streets in Shandong province were selected as subjects according to stratified random sampling from September 2019 to June 2020, and a questionnaire survey on the level of satisfaction of contracted residents′ psychological contracts(24 items) and assessment of behavior intentions(9 items) was conducted, and the model of the effect of contracted residents′ psychological contracts on behavior intentions was established and analyzed. The correlation was validated by Pearson test and the structural equation method was used for verifying the model.Results:998 valid questionnaires were recovered. The psychological contract satisfaction score of the contracted residents was 3.45±0.56 and the behavioral intention was 2.81±0.29. Both transactional and relational psychological contracts were correlated with all dimensions of behavioral intention( P<0.01). Concerning the impacts of residents′ psychological contracts on behavioral intentions, the effect coefficients of transactional psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.33, 0.24, -0.25 and -0.49 respectively, with an indirect effect on neglect intention; the effect coefficients of relational psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.26, 0.10, -0.14 and -0.50 respectively, with an indirect effect on advice intention and neglect intention. Conclusions:Residents′ psychological contract has yet not been effectively satisfied. Satisfying and improving the residents′ psychological contract can directly enhance their loyalty intention and reduce their exit intention, indirectly influencing the voice and neglect intentions. In order to enhance the effectiveness of family doctor contracted services and improve the healthcare experience of contracted residents, it is suggested that the relevant departments should actively take the following measures, including carrying out a survey on the psychological contract of contracted residents, building a provincial-city-county-township collaborative linkage platform, and so on.
ABSTRACT
Cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS) is an autosomal recessive hereditary disorder characterized by cerebellar ataxia, sensory neuropathy and bilateral vestibulopathy. Recently a biallelic intronic AAGGG repeat expansion in the replication factor C1 (RFC1) gene was identified as the cause of this disorder. Clinical studies of genetically-confirmed CANVAS in the past 2 years have significantly expanded the clinical phenotype of the disease and the concept of RFC1-related disease was proposed. The clinical manifestations, characteristic auxiliary examination, genetic changes of CANVAS were reviewed and the new diagnostic criteria to improve clinicians′ awareness of the disease was discussed in this paper.
ABSTRACT
Objective:To analyze skin manifestations of pediatric inflammatory bowel disease (IBD) .Methods:Children with IBD were collected from pediatric wards in Peking University Third Hospital from January 2010 to January 2022, and their skin manifestations were retrospectively analyzed.Results:A total of 50 children with IBD were included, including 27 with Crohn′s disease and 23 with ulcerative colitis. Twenty-five (50%) patients had skin manifestations, including specific skin manifestations in 11 (22%) and relevant skin manifestations in 11 (22%) . Specific skin manifestations included cutaneous perianal Crohn′s disease in 2 cases, and anal fistula and/or perianal abscess in 9 cases; relevant skin manifestations included erythema nodosum in 5 cases, aphthous stomatitis in 3 cases, psoriasis in 1 case, polyarteritis nodosa in 1 case, and Henoch-Sch?nlein purpura in 1 case. Compared with the ulcerative colitis group, the Crohn′s disease group was more prone to suffer from specific skin manifestations and relevant skin manifestations, and there were significant differences in the prevalence of specific and relevant skin manifestations between the two groups (both P < 0.05) . Of the 27 children with Crohn′s disease, 19 (70%) had one or more skin manifestations, 2 of whom successively presented with 4 different skin manifestations. One child with Crohn′s disease and 1 with ulcerative colitis had 3 different skin manifestations in different periods. The fecal calprotectin level was elevated in all children with skin manifestations, and in 12 (48%) children without skin manifestations. The skin lesions of 5 children were improved or subsided after dose adjustment (1 case) or switch (4 cases) of biological agents. Conclusions:Half of the children with IBD have skin manifestations, and children with Crohn′s disease are more prone to have specific and relevant skin manifestations. Different skin manifestations could be observed in the same child in different periods. Multidisciplinary teamwork is conducive to the overall control of this disease.
ABSTRACT
IL1RAPL1 gene is one of the genes related to X-linked nonspecific mental retardation(MRX), but its pathogenic mechanism has not been fully clarified.Interleukin-1 receptor accessory protein like 1(IL1RAPL1) is a synaptic adhesion molecule located on postsynaptic membrane.The mutation of IL1RAPL1 gene can lead to the deletion or dysfunction of this protein.Recent studies have shown that the IL1RAPL1 protein regulates dendritic formation and mediates the activity of IL-1β molecules on dendritic morphology.This review describes the latest advances in synaptic and neuronal functions of IL1RAPL1, and summarizes some gene mutations that have been found to be associated with mental retardation(MR)and autism spectrum disorder(ASD), to provide evidence for clinical diagnosis and treatment.
ABSTRACT
Objective:To describe the content and analyze the constitutive dimensions of the psychological contracts with residents contracted for family physician services.Methods:Based on a collection of policy documents on family doctor contracting services issued by central government ministries and relevant departments in Shandong province as well as 27 signed family doctor agreements in nine counties (cities, districts) of Shandong province, semi-structured interviews were made to 48 residents in both September 2019-January 2020 period and May-June 2020 period, regarding the verbal promises of family doctors and the needs of these contracted residents. Then the documented and non-documented commitments of the family doctors were extracted in the content analysis method, and a credibility test was made using the Myers reliability test formula.Results:A total of 639 written commitments of family doctors were obtained, covering 5 types of responsibilities and 20 commitments, and the credibility coefficient was 0.88. 322 codes of non-documented commitments were obtained, 4 commitments were added on the basis of documented commitments, and the credibility coefficient was 0.90. The psychological contracts were sorted out in such five areas as technical quality responsibility, cost control responsibility, convenient access responsibility, communication responsibility, and empathic responsibility, by matching the residents′ medical service needs obtained from the interviews, while the first three categories and the last two categories were classified as transactional and relational psychological contracts, respectively, with 10 items of technical quality responsibility accounting for the highest percentage (41.67%).Conclusions:The documented and non-documented commitments of family doctors differed in content and structure. The psychological contract signed by residents was mainly transactional, and residents had higher expectations for family doctors to provide high-quality, convenient and economical services.
ABSTRACT
SCN2A (sodium channel, voltage-gated, type Ⅱ, alpha) gene encodes neuronal voltage-gated sodium channel Na V1.2, one of the four sodium channel analogues expressed in the central nervous system, which participates in the initiation and conduction of a series of neuronal action potentials.The dysfunction of SCN2A gene is associated with a variety of neurodevelopmental disorders, and has been confirmed to be one of the main causes of epilepsy, autism spectrum disorder and mental retardation in infants.There is a strong correlation between the type of gene mutations and clinical phenotypes.The clinical symptoms of seizures can be improved by activating the function of sodium channels.This paper describes the related research on SCN2A gene-mediated epilepsy in recent years, and summarizes its clinical characteristics, which provides a new idea for treatment.
ABSTRACT
Family physicians contracted service is an important choice to deepen the reform of China′s healthcare reform and achieve the strategic goal of " health for all" . In order to effectively promote the contracted service, the central government has successively issued a number of policy documents, which are echoed by the localities in their proactive explorations, achieving remarkable results. But there are also multiple roadblocks hindering the contracted service to progress. This article referred to the three-circle theory and studied policy implementation from the three dimensions of policy value, policy resources, and policy impetus. A thorough analysis of the problems in the implementation process revealed such main problems as insufficient family physicians, inadequacy of supporting policies and low level of policy acceptance among the young healthy age groups. The follow-up work will promote the long-term implementation of the family physicians contracted service policy by enriching the family physicians team, enriching supporting policies, and focusing on promotions to key age groups.
ABSTRACT
Objective To investigate the influence of high-motivated affect background on the holistic face processing and its neural mechanism.Methods Totally 26 subjects were instructed to perform composite-face process under the priming condition of three emotional pictures (food,neutral and fear).Results (1)Behavioral studies showed a significant interaction between emotion type and face combination(F(2,50) =5.37,P=0.008).Composite-face effect was observed in neutral emotional condition due to the fact that the recognition accuracy of the misaligned face ((90.21 ± 11.20)％) was significantly higher than that of the aligned face((84.83 ± 11.20) ％,t (25) =3.95,P=0.001).However,the composite-face effect disappeared under the condition of high-motivated emotion.That is,there was no significant difference in the recognition accuracy of the misaligned faces ((87.88± 10.28)％) and aligned faces ((85.12± 8.81)％,t(25)=1.93,P=0.065) under the condition of high-motivated negative emotion.Under the condition of high-motivated positive emotion,there was also no significant difference in the recognition accuracy between the misaligned faces ((87.92±11.00)％) and aligned faces((88.33±8.89)％,t(z5)=0.263,P=0.795).(2) According to the results of ERP,P3 components showed significant interaction between emotion type and face combination form(F(2,50) =3.23,P=0.048).Under the neutral emotional condition,the P3 amplitude of aligned faces ((3.46 ± 1.26) μV) was significantly higher than that of misaligned faces ((2.82 ± 1.43)μV,F (1,25)=5.28,P=0.03).In the case of high-motivated negative condition,there was no significant difference in P3amplitude between aligned faces ((3.21 ± 1.16) μV) and misaligned faces ((3.07 ± 1.22) μV,F (1,25) =0.53,P=0.476).The P3 amplitude of aligned faces((3.33±1.20) μV) and misaligned faces((3.42±1.40) μV) were also not significantly different under the condition of high-motivated positive affect (F(1,25)=0.23,P=0.638).Conclusion The study shows a high correlation between face processing and emotional processing.Additionally,the emotional motivation has a stronger influence on face processing.Regardless of the emotional valence,high-motivated intensity affect can cause local attention bias and reduce the holistic processing level of the face,which is mainly manifested in the later cognitive processing stage.
ABSTRACT
Objective To analyze the dilemmas of our hierarchical medical system, in order to seek a viable path for effective implementation.Methods Based on the Meter-horn model, six related factors were used, including policy standards and goals, policy resources, implementation methods, characteristics of the actuator, value orientation of the executive and the system environment, to analyze the dilemmas of the implementation of hierarchical medical system.Results This policy had not achieved the expected effect in the implementation process, which deviated from the original intention of policy designers to some extent. There exist the following setbacks for the roadblocks. For example, policy standard was ambiguous, the policy resources were insufficient, the execution method was not proper, the implementation mechanism was"criticized" , the implementation personnel value orientation was biased and the complex system environment.Conclusions All the factors involved in the implementation of the hierarchical medical policy affect each other.In this consideration, medical institutions at all levels and the relevant departments should coordinate and deal with the relationship between these six related factors, and timely take effective measures to amend and improve the policy, so as to ensure the orderly progress and long-term implementation of the hierarchical medical system.
ABSTRACT
OBJECTIVE@#To investigate the association of CXCL12 and CXCR4 polymorphisms with the genetic risk and severity of coronary stenosis in patients with coronary artery disease (CAD).@*METHODS@#Competitive allele specific PCR(KASP) was performed to identify the genotypes of rs2297630 and rs2322864 polymorphisms in 302 CAD patients and 302 age-and gender-matched healthy controls. The severity of CAD patients was assessed by the Gensini scoring system according to the results of coronary arteriography. The association of rs2297630 and rs2322864 polymorphisms with genetic risk of CAD and Gensini scores were analyzed by unconditional logistic regression and multivariate linear regression respectively.@*RESULTS@#There were significant differences in the genotype and allele frequencies of both rs2297630 and rs2322864 between the CAD group and healthy control (all 0.05).@*CONCLUSIONS@#Gene polymorphism of CXCL12 rs2297630 is associated with the genetic risk of CAD and the severity of coronary stenosis. Moreover, the gene polymorphism of CXCR4 rs2322864 is associated with genetic risk of CAD, but not with the severity of coronary stenosis.

Objective To systematic review the influence of case-based payment on inpatient costs since China′s new medical reform. Methods Studies about inpatient costs before and after the implementation of case-based payment were collected. The literature collected underwent a meta-analysis by RevMan 5. 0. Results A total of 11 articles in compliance were included in the study. The meta-analysis of random effect model showed the overall effect size (SMD) was -1. 54 with 95% CI being -1. 79, -1. 29, showing a significant difference (P<0. 05). The subgroup analysis showed that the overall effect size (MD) in the low-cost disease group was -585. 57 yuan with 95% CI being -750. 34, -420. 80, showing a significant difference (P < 0. 05). The overall effect size (MD) in the high-cost disease group was-4 172.65 yuan with 95% CI being -5 368. 21, -2 977. 10, showing a significant difference ( P <0.05). The funnel plot was approximately symmetrical, suggesting a publication bias as less likely in the study. Conclusions The implementation of case-based payment has reduced the inpatient costs to some extent thanks to China′s new healthcare reform. And the effect in the high-cost disease group was more obvious than that in the low-cost disease group.
ABSTRACT
Objective To evaluate the diagnostic value of T-cell enzyme-linked immunosorbent spot assay (T-SPOT.TB) using both pleural effusion and peripheral blood in tuberculous pleurisy.Methods One hundred and two cases of in patients with pleural effusion treated in Anhui Chest Hospital from January 2014 to October 2015 were enrolled in this study.T-SPOT.TB was performed using both serous effusion mononuclear cells (SEMC) and peripheral blood mononuclear cells (PBMC),and the diagnostic sensitivity and specificity were calculated.Chi square test was used for categorical variables and MannWhitney U test was used for continuous variables in non-normal distribution.Results Of the 102 participants,71 (69.61 ％) were microbiologically or clinically diagnosed with tuberculous pleurisy and 31 (30.39 ％) were diagnosed with other diseases.In tuberculous pleurisy group,the median spot forming cells (SFC) of T-SPOT.TB for early secretory antigenic target 6 (ESAT-6) and culture filtrate protein 10 (CFP-10) using SEMC were 159/2.5 × 105 (120/2.5 × 105-200/2.5× 105) and 160/2.5 × 105 (110/2.5 × 105-210/2.5 × 105),respectively;and the median SFC of T-SPOT.TB using PBMC were 30/2.5×105 (15/2.5×105-55/2.5×105) and 40/2.5×105(8/2.5×105-87/2.5 ×105),respectively.The SFC counts of SEMC were obviously higher than those of PBMC,and differences were statistically significant (for ESAT-6,Z=-7.818;for CFP-10,Z=-7.120,both P＜0.05).The ROC curve analysis showed that using a cut-off value of 38 SFC per 2.5 × 105 SEMC,the area under the curve is 0.969.The sensitivity and specificity of T-SPOT.TB using PBMC were 90.14％ and 77.42％,respectively;and those of T-SPOT.TB using SEMC were 95.77％ and 93.55％,respectively.When combined the T-SPOT.TB assay using both PBMC (≥6 spots) and SEMC (≥38 spots),the sensitivity and specificity were 90.14％ and 96.77％,respectively.Conclusion The joint detection of T-SPOT.TB using both PBMC and SEMC can be an effective diagnostic method for tuberculous pleurisy.
ABSTRACT
Objectives:The objective of this study is to make suggestions for the internet medical development. Methods:Based on the field survey, this paper analyzes three kinds of internet medical mode in China, and sums up the pros and cons. Results:The internet medical has the ability of technically providing healthcare by internet, and meeting the patients’ essential health care requirements. The problems mainly include health insurance, regional dis-tribution, electronic prescription audit, electronic medical record and safekeeping the record files, operation supervi-sion etc. The corresponding countermeasures include elaborating laws, gradually completing the internet medical and health insurance cooperation, the government’s regional division handling, setting up a special supervision department in the hospitals etc. Conclusion:It is important to clear the internet medical related problems and develop a model which is suitable for healthcare institutions.
