Objective To investigate the trend of the national Kaschin-Beck disease condition, and provide the scientific basis for the government to make preventing strategy. Methods The data were collected from national surveillance on Kaschin-Beck disease(KBD) condition from 2000 to 2007 by restrospective method. The national X-ray detective rates and KBD condition in the eastern and western areas of China were analyzed. Results Monitoring data were collected from 189 monitoring points in 14 provinces of China, and 21 287 X-ray films were photographed of right hands of children from 2000 to 2007. X-ray detective rate was decreased significantly of national KBD from 2000 to 2007. The condition in the west of China is slightly more serious than the eastern areas, but the average of X-ray detective rate was also decreased from 21.75% to 7.30%. National condition is basically controlled. X-ray detective rate had been controlled below 5%, exept for Qinghai, Tibet and Inner Mongolia and so on. Conclusions Ninty percent of the wards have reached the controlled level according to the X diagnosis standard. In terms of the severity of the disease, most of the wards are occupied by patients with slight condition, 10% ward with moderate condition, less than 1% ward with serious condition.

Objective: To examine the effect of SiO2 exposure on the airway surface microenvironment and NIMA-related kinase 7 (NEK7)/nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome in rats. Methods: Twenty-four specific pathogen-free male rats of the SD strain were randomly divided into the control group and the model group, of 12 rats in each group. Rats in the model group were given SiO2 suspensions through disposable tracheal intubation perfusion to model silicosis in rats, while rats in the control group was perfused with the same amount of physiological saline. The pH value and glucose level were measured in the rat bronchoalveolar lavage fluid (BALF) 14 and 28 days after modeling. Lung tissues were stained with HE and Masson and the distribution of inflammatory cells and the deposition of pulmonary interstitial collagens were observed in lung tissues under a light microscope. The expression of transforming growth factor β1 (TGF-β1), collagen type Ⅰ(ColⅠ), collagen type Ⅲ (Col Ⅲ), interleukin-1β (IL-1β), NLRP3, N-terminal domain of Gasdermin D (GSDMD-NT), caspase-1, and NEK7 was quantified in lung specimens using immunohistochemistry. Results: Lower pH values were measured in rat BALF in the model group than in the control group 14 [(6.38±0.05) vs. (6.68±0.08), P<0.05] and 28 days after modeling [(6.63±0.14) vs. (6.86±0.05), P<0.05], while higher glucose levels were seen in the model group than in the control group 14 [(0.39±0.06) vs. (0.31±0.04) mg/dL, P<0.05] and 28 days after modeling [(0.39±0.08) vs. (0.31±0.06) mg/dL, P<0.05]. HE and Masson staining showed mild to moderate alveolitis and pulmonary fibrosis in rats 14 days post-exposure to SiO2, and showed moderate to severe alveolitis and pulmonary fibrosis 28 days post-exposure. Immunohistochemistry detected higher TGF-β1, ColⅠ, Col Ⅲ, IL-1β, NLRP3, GSDMD-NT, caspase-1 and NEK7 expression in rat lung tissues in the model group than in the control group (all P<0.05). Conclusions SiO2 exposure may cause changes in rat airway surface microenvironment, including BALF acidification and elevated glucose. Pyroptosis induced by activation of NEK7-associated NLRP3 inflammasome may be an important mechanism of pulmonary fibrosis caused by silicosis.

Objective To investigate the value of detecting HEART score and HEARTS3 score in risk stratification and prognosis of acute coronary syndrome (ACS) in patients with non-ST segment elevation chest pain in emergency department (ED).Methods Clinical data of case-control retrospective study of 775 patients with non-ST segment elevation chest pain in ED were collected from July 2011 to March 2015.The patients were estimated and risk stratification was made with HEART score and HEARTS3 score.After follow-up visiting by telephone for 30 days,outcomes were found to be ACS and myocardial infarction (MI).And the patients were categorized with score into low,intermediate and high risk groups.The correlation between the ACS and risk score in three groups was analyzed.Comparison of capability of performance in predicting 30-day ACS between the HEART score and HEARTS3 risk score.Statistical analyses were performed using SPSS13.0.Enumeration variables were expressed as percentage.For comparison of predictive value of the two sets of scores,area under the receiver operating curve (auROC) was calculated and compared by Z test.Results There were 92 cases with 30-day ACS.The rate of ACS had a trend of increase with increase in HEART score and HEARTS3 score.The patients with higher scores of HEART and HEARTS3,higher incidence of ACS in 30 days.Especially,the high-risk patients with score≥7 of HEART score and≥8 of HEARTS3 score had higher rate of ACS.And there was significant difference in predicting high-risk patients between two sets of scoring (P ＜ 0.05).The HEARTS3 score outperformed the HEART score as determined by comparison of areas under the ROC curve for MI (0.952 vs 0.813;P =0.028),30-day ACS (0.913 vs.0.815;P =0.034).Conclusions HEART score and HEARTS3 score both can be used to evaluate and perform risk stratification for non-ST segment elevation chest pain patients in ED.But HEARTS3 score can more precisely stratify high-risk patients with chest pain for 30-day ACS.

Objective To identify the clinical and imaging characteristics in neonatal refractory purulent meningitis. Methods Clinical data of 70 cases of neonatal purulent meningitis admitted to the neonatal intensive care unit at Children's Hospital of Fudan University from January, 2009 to December, 2014 were reviewed retrospectively. The patients were divided into refractory group (n=28) and non-refractory group (n=42) according to the course of antimicrobial therapy.The clinical and brain MRI characteristics of neonatal refractory purulent meningitis were analyzed. Parameters were compared between the two groups using Chi-square or Fisher's exact tests, and Wilcoxon tests where appropriate. Risk factors of neonatal refractory purulent meningitis were investigated by univariate and multivariate Logistic regression analysis. Results Among the 70 cases, 31(44.3%) were positive for cerebrospinal fluid (CSF)/blood culture. The positive rate was higher in the refractory group than in the non-refractory group [75.0%(21/28) vs 23.8%(10/42),χ2=17.843, P<0.01]. The most common pathogenic bacteria isolated in the refractory group were Escherichia coli [8 cases (38.1%)] and group B streptococci [5 cases (23.8%)]. Compared to the non-refractory group, patients in the refractory group were more likely to have seizure, higher CSF white blood cell count, higher CSF protein concentration and lower CSF glucose concentration [53.6%(15/28) vs 7.1% (3/42), 965.0 (463.0-2 200.0)×106/L vs 116.5 (61.0-327.5)×106/L, 3 221.1(2 354.3-4 633.5) mg/L vs 1 487.6(988.2-1 924.1) mg/L, and 0.2 (0.1-0.8) mmol/L vs 1.5 (1.2-1.8) mmol/L; all P<0.01]. Multivariate Logistic regression analysis showed that seizure, low CSF glucose concentration on admission, and a positive CSF/blood culture result neonatal refractory purulent meningitis (OR=9.6, 95%CI: 1.2-76.0; OR=15.0, 95%CI: 5.6-63.3; and OR=7.3, 95%CI: 1.5-36.0, respectively). Abnormal brain MRI findings, including intracranial extracerebral space abnormality, ventricular dilatation and periventricular white matter injury, were more common in the refractory group [100.0%(28/28) vs 61.9%(26/42), χ2=13.827 totally; 64.3%(18/28) vs 21.4%(9/42), χ2=13.023 for intracranial extracerebral space abnormality; 60.7%(17/28) vs 19.0%(8/42), χ2=12.704 for ventricular dilation and 28.6%(8/28) vs 2.4%(1/42) for periventricular white matter injury; all P <0.01]. Compared with the non-refractory group, the refractory group had a longer hospital stay [(48.0±17.4) d vs (26.0±10.2) d, t=6.016, P<0.01] and more adverse events [67.9%(19/28) vs 31.0%(13/42), χ2=9.220, P=0.002], including hearing impairment and requirement of neurosurgical intervention [14/18 ears vs 10/46 ears (21.7%), χ2=4.292, P=0.038]. There was no death in both groups during hospitalization. Conclusions Neonates with seizure, low CSF glucose concentration and positive CSF/blood culture results are more likely to have refractory purulent meningitis. Brain MRI abnormalities are more common in neonatal refractory purulent meningitis.

Objective To investigate the clinical features of neonatal invasive fungal infection(IFI) so as to guide diagnosis,prevention and treatment of IFI.Methods Seventy-six neonates with IFI admitted to the Neonatal Intensive Care Unit (NICU) at Children's Hospital of Fudan University from 2004 to 2014 were included in the study.Pathogens,clinical manifestation,risk factor exposure,laboratory findings,complications,and clinical outcome of neonatal IFI were analyzed.Results Seventy-six cases were diagnosed as IFI between 2004 and 2014,with an yearly increasing trend.Sixty-eight patients were premature infants (89.5％).Of the 76 cases,except one with unknown birth weight,11(14.7％),34(45.3％),20(26.7％)and 10 (13.3％) cases had birth weight ＜ 1 000 g,(≥ 1 000-＜1 500) g,(≥ 1 500-＜2 500) g and ≥ 2 500 g,respectively.The pathogens were mainly Candida (74/76,97.4％),including 26 cases of Candida albicans (34.2％).However,the incidence of non-Candida albicans infection was increasing.Candida guilliermondii was the most common in nonCandida albicans,accounting for 29.2％ (14/48).All Candida albicans were sensitive to fluconazole.One strain of Candida glabrata was resistant to fluconazole.The most common risk factors included use of broad-spectrum antibiotics(93.3％,56/60),parenteral nutrition(70.0％,42/60),central vein catheterization(53.3％,32/60),invasive ventilation(40.0％,24/60) and history of abdominal surgery(21.7％,13/60).Clinical manifestations of IFI included temperature instability,frequent apnea,increased requirement of respiratory support and feeding intolerance.Among all cases,six were diagnosed as central nervous system infection.Of the patients who received cranial MRI,46.8％(22/47) showed multiple abnormal signals in cerebral parenchyma.Fiftytwo patients were cured and seven patients died before discharge,including one death due to fungal infection.Conclusions There is an increasing trend of IFI cases in NICU,especially in premature infants.Non-Candida albicans has become the main pathogenic fungus.There are no specific clinical manifestations in neonatal IFI.Use of broad-spectrum antibiotics,parenteral nutrition and central venous catheterization are common risk factors,and preventive measures should be taken in high-risk infants.In addition,IFI in neonates may affect important organs such as central nervous system,thus early treatment is necessary in suspected patients.

Objective To compare early-stage clinical features and hypothalamic-pituitary-adrenal (HPA) axis neuroendocrine function in first-episode and untreated major depressive disorders with suicide and without suicide. Methods Untreated patients who had a diagnosis as major depression according to ICD-10 were allocated to suicide with major depressive disorder group or non-suicide with major depressive disorder group according to whether the pa?tients had suicidal ideation or behaviours. Patients were assessed before treatment using the 17-item Hamilton Depres?sion Scale (HAMD-17), the Hamilton Anxiety Scale (HAMA), the Yale-Brown Obsessive Compulsive Scale (YBOCS) and the suicide assessment scale. The cortisol (CORT) and adrenocorticotropic hormone (ACTH) levels in serum were measured using a chemiluminescence immunoassay. Results There was no significant difference in demographic data be?tween the two groups (P>0.05). In early-stage clinical features, there were significant differences in changes of sexual ac? tivity and feeling of despair (P<0.05). HAMD total scores were significantly higher in the suicide group (P<0.01), whereas HAMA total scores and Y-BOCS total scores were not significantly different between the two groups (P>0.05). There were no significant differences in CORT or ACTH levels between two groups (P>0.05). There were no significant correlation of suicidal scores with early-stage clinical features, symptom scales scores, CORT or ACTH levels (P>0.05). Conclusion De?creased sexual desire and feeling of despair are more severe in depressed patients with suicide than those without. There is no correlation of early-stage clinical features or HPA axis functions with suicide in patients with depression.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.
