Investigation of Listeriosis-Related Knowledge, Attitudes, and Practices Among Medical Staff in Fangshan, Beijing, China.

The aim of this study was to gain insight into the knowledge of, attitude toward, and practical experience with listeriosis among medical staff. In two hospitals in Fangshan, Beijing, 410 medical staff members were randomly selected using a random sampling method. Each selected staff member was invited to participate in a standardized questionnaire interview. In total, 397 valid questionnaires were collected. With regard to the staff members' general knowledge of listeriosis, they answered 65.96% of the items correctly. The knowledge scores among obstetricians and gynecologists were higher than those of other clinical doctors (p < 0.05); however, obstetricians and gynecologists were less knowledgeable about which drugs are effective against listeriosis than the other doctors (p = 0.007). The percentage of participants with a positive attitude about preventing listeriosis was 96.47%, the percentage with practice formation was 52.39%. The medical staff's mean score for knowledge of listeriosis was 4.61 ± 1.83. The mean score for attitude toward listeriosis was 9.71 ± 1.31. There was a significant association between attitude and knowledge of listeriosis (r = 0.221, p < 0.001). Medical staff obtained a mean score of 2.10 ± 1.07 for the practice formation. There was a significant association between practice formation and knowledge of listeriosis (r = 0.502, p < 0.001). The mean knowledge-attitude-practice (KAP) score for listeriosis among medical staff was 16.41 ± 3.19. The KAP scores were significantly correlated with age (r = 0.129, p = 0.011), occupation (r = -0.103, p = 0.041), department (r = -0.168, p = 0.001), and professional title (r = 0.166, p = 0.001). To improve medical outcomes and foodborne disease surveillance, medical staff should receive more training on listeriosis and the content of the training should be adjusted.

[Effects of cyclooxygenase-2 selective inhibitor celecoxib on the expression of major vault protein in rats with status epilepticus].

OBJECTIVE: To study the effect of cyclooxygenase -2 selective inhibitor celecoxib on the expression of major vault protein ( MVP) in the brain of rats with status epilepticus and its possible roles in the treatment of refractory epilepsy. METHODS: Sixty adult male Sprague-Dawley rats were randomly assigned to blank control (n=16), epilepsy model (n=22) and celecoxib treatment groups (n=22). After the status epilepticus was induced in rats by injecting lithium and pilocarpine, each group had 16 rats enrolled as subjects. Immunohistochemical method and Western blot method were used to detect the expression of MVP in the frontal cortex and hippocampus. RESULTS: The expression of MVP was significantly higher in the epilepsy model group than in the control group (P<0.01). The expression of MVP in the celecoxib treatment group was significantly decreased compared with the epilepsy model group, but it was still higher than in the control group (P<0.01). CONCLUSIONS: Celecoxib could decrease the expression of MVP in brain tissue of rats with status epilepticus, suggesting that it is promising for the treatment of intractable epilepsy.

[Relationship between brachial-ankle pulse wave velocity and glycemic control of type 2 diabetes mellitus patients in Beijing community population].

OBJECTIVE: To explore the correlation between glycemic control of type 2 diabetes mellitus (T2DM) patients and brachial-ankle pulse velocity (baPWV). METHODS: A community-based cross-sectional study was conducted in Beijing, China. Every subject underwent physical examinations, glycated hemoglobin (HbA1c), blood lipid and baPWV measurements and completed a standardized questionnaire. T2DM patients were divided into well controlled and poorly controlled groups according to HbA1c levels. The correlation between glycemic control of T2DM patients and baPWV was analyzed. RESULTS: In this study, 1 341 subjects were recruited, including 733 T2DM patients and 608 non-diabetes subjects. Compared with non-diabetes subjects, abnormal baPWV (baPWV≥1 700 cm/s) rate for T2DM patients was higher (40.8% vs. 26.8%, P<0.001). With HbA1c<6.5% or <7.0% as the aim of glycemic control in T2DM patients, the abnormal baPWV rates for non-diabetes subjects, well controlled and poorly controlled T2DM patients were significantly different (non-diabetes vs. HbA1c<6.5% T2DM vs. HbA1c≥6.5% T2DM: 26.8% vs. 32.8% vs. 42.6%, P<0.001; non-diabetes vs. HbA1c<7.0% T2DM vs. HbA1c≥7.0% T2DM: 26.8% vs. 36.1% vs. 43.4%, P<0.001). After being adjusted for gender, age, smoking status, diabetes mellitus family history, T2DM duration, cardiovascular diseases (CVD), waist hip ratio (WHR), systolic blood pressure (SBP), diastolic blood pressure (DBP), total triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C), the Logistic regression models suggested that glycemic control status of T2DM patients was associated with abnormal baPWV. Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<6.5% T2DM patients and HbA1c≥6.5% T2DM patients were 0.927(95%CI 0.560-1.537) and 1.826 (95%CI 1.287-2.591). Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<7.0% T2DM patients and HbA1c≥7.0% T2DM patients were 1.210 (95%CI 0.808-1.811) and 1.898 (95%CI 1.313-2.745). CONCLUSION: The glycemic control status of T2DM patients from communities is significantly associated with baPWV. Poor glycemic control is a risk factor for abnormal baPWV. Keeping HbA1c under control might lower the risk of cardiovascular diseases in T2DM patients.

Effectiveness of vagus nerve stimulation for drug-resistant generalized epilepsy in children aged six and younger.

BACKGROUND: To explore a novel scoring system to evaluate the efficacy of vagus nerve stimulation (VNS) in children with drug-resistant generalized epilepsy (DRGE) aged six and younger. BASIC PROCEDURES: The data of twelve children with DRGE under the age of 6 years who accepted VNS and have been followed up for at least 3 years were retrospectively reviewed. The outcome was evaluated with the McHugh Classification System and a novel scoring system we proposed. MAIN FINDINGS: Based on the McHugh Classification System, the total response rate was 91.67% (11/12) and the rate of Grade I was 41.67% (5/12). A novel scoring system involving seizure frequency, seizure duration and quality of life (QOL) was proposed, by which the outcome was scored from -3 to 11 and graded from IV to I. Based on the novel scoring system, the total response rate was 91.67% (11/12) and the rate of Grade I was 33.33% (4/12). The incidence of complication was 16.67% (2/12). The efficacy of VNS appeared a gradually improving trend with plateau or fluctuation over time. Shorter course of epilepsy prior to VNS may be related to better outcome. PRINCIPAL CONCLUSIONS: VNS could effectively reduce the seizure frequency and improve the QOL of children with DRGE aged six and younger. The novel scoring system was comprehensive and feasible to evaluate the efficacy of VNS. The time pattern of the long-term efficacy of VNS requires further investigation.

CHD4 variants are associated with childhood idiopathic epilepsy with sinus arrhythmia.

AIMS: CHD4 gene, encoding chromodomain helicase DNA-binding protein 4, is a vital gene for fetal development. In this study, we aimed to explore the association between CHD4 variants and idiopathic epilepsy. METHODS: Trios-based whole-exome sequencing was performed in a cohort of 482 patients with childhood idiopathic epilepsy. The Clinical Validity Framework of ClinGen and an evaluating method from five clinical-genetic aspects were used to determine the association between CHD4 variants and epilepsy. RESULTS: Four novel heterozygous missense mutations in CHD4, including two de novo mutations (c.1597A>G/p.K533E and c.4936G>A/p.E1646K) and two inherited mutations with co-segregation (c.856C>G/p.P286A and c.4977C>G/p.D1659E), were identified in four unrelated families with eight individuals affected. Seven affected individuals had sinus arrhythmia. From the molecular sub-regional point of view, the missense mutations located in the central regions from SNF2-like region to DUF1087 domain were associated with multisystem developmental disorders, while idiopathic epilepsy-related mutations were outside this region. Strong evidence from ClinGen Clinical Validity Framework and evidences from four of the five clinical-genetic aspects suggested an association between CHD4 variants and epilepsy. CONCLUSIONS: CHD4 was potentially a candidate pathogenic gene of childhood idiopathic epilepsy with arrhythmia. The molecular sub-regional effect of CHD4 mutations helped explaining the mechanisms underlying phenotypic variations.

[Effects of valproate acid on blood lipid, serum leptin and cerebral cortex in juvenile and adult rats].

OBJECTIVE: To study the effects of valproate acid (VPA) on serum lipid and leptin levels and cerebral cortex in juvenile and adult rats. METHODS: Twenty healthy juvenile female Sprague-Dawley (SD) rats (21-day-old) and twenty healthy adult female SD rats (2-month-old) were randomly divided into four groups (n=10 each): juvenile control, juvenile VPA, adult control and adult VPA. Juvenile and adult VPA groups were fed with VPA 200 mg/kg daily, while the two control groups were fed with normal saline. The body weights were recorded weekly. Six weeks after feeding, serum and brain samples were obtained. Serum lipid levels including total cholesterol (TC), triglycerides (TG) and lower density lipoprotein cholesterol (LDL-C) were determined. Serum leptin (LEP) levels were measured by radioimmunoassay (RIA). Myelin staining and Nissl staining were used to evaluate the changes of brain tissues. RESULTS: The weight and serum LEP and lipid levels in both juvenile and adult VPA groups increased significantly compared with those in the control groups (P<0.05). The juvenile VPA group had more increased serum LEP and lipid levels than the adult VPA group (P<0.05). The Myelin staining showed that the average fiber density in the VPA groups was significantly lower than that in the control groups (P<0.05). The Nissl staining showed that the number of toluidine blue staining neurons in the VPA groups was not statistically different from the control groups. CONCLUSIONS: VPA may increase serum LEP and lipid levels in both juvenile and adult rats, and more increased levels may be found in juvenile rats. Long-term VPA treatment may have an adverse effect on brain myelination, but no effect on neurons.

[Effect of astrocytes with different degrees of proliferation on multidrug resistance gene expression in rats with epilepsy].

OBJECTIVE: To study the relationship of activated astrocytes and multidrug resistance gene (MDR) expression in rats with epilepsy. METHODS: Astrocytes of neonatal Sprague-Dawley rats were separated and cultured. The cultured cells of passage 3 were activated by TNF-α for 2, 24 or 48 hrs. The culture media of cells with different degrees of proliferation were infused to the lateral cerebral ventricle of rats with epilepsy. The expression of MDR in the brain tissue was ascertained by PCR, immunocytochemistry and Western blot. RESULTS: After 2 hrs of TNF-α stimulation, astrocytes began to proliferate, and reached a peak at 24 hrs. The expression of MDR in the brain tissue increased after infusion of culture medium of proliferated astrocytes in the TNF stimulation group compared with that in the control group without TNF stimulation. The level of MDR expression in the TNF stimulation group was positively correlated with the degrees of cell proliferation. CONCLUSIONS: Proliferation of astrocytes can increase the expression of MDR in rats with epilepsy and is probably involved in the development of refractory epilepsy.

Entecavir add-on Peg-interferon therapy plays a positive role in reversing hepatic fibrosis in treatment-naïve chronic hepatitis B patients: a prospective and randomized controlled trial.

BACKGROUND: The efficacy of entecavir (ETV) add-on peg-interferon therapy compared with ETV monotherapy in treatment-naïve hepatitis B virus (HBV) patients remains controversial. We investigated whether adding peg-interferon to ongoing ETV treatment leads to a better curative effect or not. METHODS: All patients have been recruited between August 2013 and January 2015 from the Shanghai Public Health Clinical Center and Zhongshan Hospital (China). Eligible HBV patients (n = 144) were randomly divided (1:1) to receive either ETV monotherapy (n = 70) or peg-interferon add-on therapy from week 26 to 52 (n = 74). Patients were followed-up for at least 2 years. Indexes including hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) seroconversion rate, sustained virologic response, transient elastography value, and histological scores were evaluated every 3 months until the end of the study. The rate of patients with HBsAg loss was defined as the primary endpoint criteria. RESULTS: At week 26, no patient achieved HBsAg seroconversion in either group. At week 52, one patient in the monotherapy group was HBsAg-negative but there was none in the combination therapy group. The monotherapy group showed significantly better liver function recovery results than the combination therapy group. At week 78, one patient in the combination group had HBsAg seroconverted. At week 104, only three patients in the combination therapy group were HBsAg-negative compared with one patient in monotherapy. The mean alanine aminotransferase and aspartate aminotransferase levels and transient elastography values decreased significantly compared with baseline. Both groups showed a favorable decrease in alpha-fetoprotein (monotherapy: 4.5 [2.8, 7.1] vs. 2.2 [1.8, 3.1] ng/mL, P < 0.001; combination therapy: 5.7 [3.0, 18.8] vs. 3.2 [2.0, 4.3] ng/mL, P < 0.001) and an improved result of liver biopsy examination scores. The combination group showed a better improvement in histology compared with the monotherapy group (mean transient elastography value 6.6 [4.9, 9.8] vs. 7.8 [5.4, 11.1] kPa, P = 0.028). But there was no significant difference in HBsAg conversion rate (1.8% [1/56] vs. 4.1% [3/73], P = 0.809) and HBeAg conversion rate (12.5% [7/56] vs. 11.0% [8/73], P = 0.787), as well as HBV-DNA, sustained virologic response (93.2% vs. 98.5%, P = 0.150) between the two groups. CONCLUSIONS: Both therapies supported liver function recovery and histology improvement. Combination therapy did not show better anti-viral efficacy in HBsAg or HBeAg seroconversion compared with monotherapy. However, combination therapy played a more positive role in reversing hepatic fibrosis compared with monotherapy.

[Relationship between the polymorphisms of GDI1, children NSMR and their intelligence in Qinba region].

The subjects of this study were recruited from Zha Shui and An Kang counties in the Qinba mountain region located in Middle-west China. The present study discussed the relationship between the variations of GDI1 with the children NSMR and their intelligence levels. The case-control association analysis method was used to analyze the association between the polymorphisms of two functional SNPs (rs2276462 and rs11549300) located in splicing site of the seventh exon and the eighth exon respectively, with NSMR and their different intelligence levels. It does not find out the polymorphism of rs2276462, because of its conservation. The results of case-control analysis indicated that, no association between the rs11549300 polymorphisms and children NSMR (P >0.05), but its polymorphisms may be related to intelligence levels of children in Qinba region (P =0.03). And a further work should be done to verify the conclusion of this study using the more genetic markers of GDI1 in a larger sample.

[Anassociation study between OPHN1 gene rs492933 polymorphism and mental retardation in children of the Qinba Mountain region.].

The OPHN1 gene encodes a Rho-GTPase activating protein (RhoGAP), and mutations in OPHN1 are responsible for non-specific X-linked mental retardation (NSMR). A SNP located in the 5'-untranslated region (UTRs) of OPHN1 (rs492933) was examined by PCR-RFLP to assess its contribution to cognitive ability in 234 unrelated healthy and MR children in the Qinba Mountain region in Shaanxi. The allelic frequencies of rs492933 were 0.826 for the C allele and 0.174 for the T allele. Genotype frequencies and allelic frequencies were not significantly different between the MR and the controls, or between the borderline group and the controls. In conclusion, there is no association between the OPHN1 gene polymorphism and NSMR in the Qinba Mountain region children.

[Protective effect of fructose-1,6-diphosphate against ultrastructural damage in the hippocampus of rats with repeated febrile seizures].

OBJECTIVE: Fructose-1, 6-diphosphate (FDP), serving as a cellular energy substance, has shown its roles in the treatment of hypoxic-ischemic encephalopathy and myocardial damage. The present study aimed at exploring the potentiality of the protective effect of FDP against ultrastructural damage of the hippocampus caused by febrile seizures (FS) in rats. METHODS: Thirty-six 21-day-old male Sprague-Dawley rats were randomly divided into three groups: untreated FS (control), high-dose FDP-treated FS and low-dose FDP-treated FS. FS were induced by hyperthermal bath. Thirty minutes before FS induction, rats in the high-dose and low-dose FDP-treated groups received a peritoneal injection of FDP at a dosage of 50 and 25 mg per 100 g of body weight respectively, whereas the same volume of 0.9% sodium chloride solution were injected to the rats in the control group. Transmission electron microscopy was used to examine the ultrastructural pathologic changes of neurons and organelles as well as the features of synaptic morphological parameters in the hippocampal CA1 area. RESULTS: Neuronal degeneration and necrosis, mitochondria swelling, polyribosomes disaggregation from endoplasmic reticula, and golgiosomes dilation in the hippocampal CA1 area in the two FDP intervention groups were less severe compared with the control group. FDP treatment resulted in significant increases in postsynaptic density thickness (F=12.47, P<0.01), synaptic active zone length (F=14.75, P<0.01) and synaptic interface curvature (F=3.77, P<0.05), as well as a shorter interspace of neural synapses (F=7.29, P<0.01) when compared with the control group. There were no significant differences in the ultrastructural changes between the two FDP treatment groups. CONCLUSIONS: FDP can ameliorate ultrastructural damage in the hippocampus caused by FS in rats. However, further research is warranted for a reasonable and effective dosage of FDP.

Induction of Apoptosis in Pterygium Cells by Antagonists of Growth Hormone-Releasing Hormone Receptors.

Purpose: The aim of the study was to investigate the signaling of growth hormone-releasing hormone receptor (GHRH-R) in the pathogenesis of pterygium and determine the apoptotic effect of GHRH-R antagonist on pterygium epithelial cells (PECs). Methods: Fourteen samples of primary pterygium of grade T3 with size of corneal invasion ≥ 4 mm were obtained for investigation by histology, immunofluorescence, electron microscopy, explant culture, and flow cytometry. Results: We found that PECs were localized in the basal layer of the epithelium in advancing regions of the head of pterygium. These cells harbored clusters of rough endoplasmic reticulum, ribosomes, and mitochondria, which were consistent with their aggressive proliferation. Immunofluorescence studies and Western blots showed that GHRH-R and the downstream growth hormone receptor (GH-R) were intensively expressed in PECs. Their respective ligands, GHRH and GH, were also elevated in the pterygium tissues as compared to conjunctival cells. Explanted PECs were strongly immunoreactive to GHRH-R and exhibited differentiation and proliferation that led to lump formation. Treatment with GHRH-R antagonist MIA-602 induced apoptosis of PECs in a dose-dependent manner, which was accompanied by a downregulation of ERK1 and upregulation of Caspase 3 expression. Conclusions: Our results revealed that GHRH-R signaling is involved in survival and proliferation of PECs and suggest a potential therapeutic approach for GHRH-R antagonist in the treatment of pterygium.

[Effects of topiramate and valproate acid on serum insulin and leptin levels in young and adult rats].

OBJECTIVE: To study the effects of topiramate (TPM) and valproate acid (VPA) on serum insulin and leptin levels in young and adult rats. METHODS: Thirty healthy female young rats (21 days old) and thirty healthy female adult rats (2 months old) were randomly administered with TPM (50 mg/kg daily), VPA (200 mg/kg daily) or normal saline (control group) by intragastric administration for 5 weeks. After 5 weeks, serum leptin and insulin levels were detected by radioimmunoassay (RIA). RESULTS: Serum leptin and insulin levels in both the young and adult TPM groups were remarkably lower than those of the corresponding control group (P < 0.05). The adult TPM group had significantly lower serum leptin and insulin levels than the young TPM group (P < 0.05). In contrast, serum leptin and insulin levels in both the young and adult VPA groups were remarkably higher than those of the corresponding control group (P < 0.05). The young TPM group had significantly higher serum leptin and insulin levels than the adult TPM group (P < 0.05). CONCLUSIONS: TPM decreases serum leptin and insulin levels in young and adult rats, especially in adult rats. VPA increases serum levels of both in young and adult rats, especially in young rats.

Clinical features of benign epilepsy of childhood with centrotemporal spikes in chinese children.

This multicenter clinical trial was conducted to examine current practice of benign epilepsy with centrotemporal spikes and especially address the question that in what circumstances 1 antiepileptic drug (AED) should be preferred.Twenty-five medical centers participate in this clinical trial. The general information, clinical information, and treatment status were collected under the guidance of clinicians and then analyzed. Difference between different treatment groups was compared, and usefulness of the most commonly used AEDs was evaluated.A total of 1817 subjects were collected. The average age of the subject was 8.81 years. The average age of onset is 6.85 years (1-14 years). Male-to-female ratio is 1.13:1. A total of 62.9% of the patients are receiving monotherapies, and 10.6% are receiving multidrug therapy. Both age and course of disease of treated rolandic epilepsy (RE) patients are significantly different from those of untreated patients. Bilateral findings on electroencephalography (EEG) are less seen in patients with monotherapy compared with patients with multidrug therapy. Except for 25.4% patients not taking any AEDs, oxcarbazepine (OXC), sodium valproate (VPA), and levetiracetam (LEV) are the most commonly used 3 AEDs. VPA and LEV are commonly used in add-on therapy. OXC and LEV are more effective as monotherapy than VPA.Age of onset of Chinese RE patients is 6.85 years. Bilateral findings on EEG could be a risk factor to require multidrug therapy. In Chinese patients, OXC, VPA, and LEV are most commonly used AEDs as monotherapy and OXC and LEV are more effective than VPA.

Association between a functional COMT polymorphism, mental retardation and cognition in Qinba area children.

Catechol-O-methyl transferase (COMT) plays an important role in the metabolism of neurotransmitters. Two alleles of the COMT gene as a result of a G/A transition in the exon 4 can lead to different COMT enzymatic activities. Much genetic research has revealed that this COMT functional polymorphism was related to human psychiatric disorders. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods were used to discern the relationships among the functional polymorphism of COMT, mental retardation (MR), and general cognitive ability of children. The results of the case-control analysis showed that there was no association between the frequencies of genotypes of COMT and MR (chi2=0.776, P>0.05) or between the frequency of COMT alleles and MR (chi2=0.335, P>0.05). COMT polymorphism was found in children whose intelligence quotient (IQ) was above 55. In normal children (IQ> or =85), the frequencies of high-activity allele COMTH and the homozygote genotype COMTHH were 60.98% and 79.28%, respectively. Both were higher than those of the borderline group (46.67% and 70.67%, 0.10 > P>0.05). Therefore, the result of this study suggests that this functional polymorphism is not an important risk factor for MR, but the COMTHH genotype may have a positive effect on cognitive performance in normal children in the Qinba area.

Short-term use of antiepileptic drugs is neurotoxic to the immature brain.

Previous studies have shown that the long-term use of antiepileptic drugs can cause nervous system damage. However, short-term antiepileptic drug treatment is frequently given to infants, especially neonates, to control seizure. Whether the short-term use of antiepileptic drugs is neurotoxic remains unclear. In the present study, immature rats, 3-21 days of age, were intraperitoneally injected with phenobarbital and/or topiramate for 3 consecutive days. Hematoxylin-eosin and immunohistochemical staining revealed that phenobarbital and topiramate, individually or in combination, were cytotoxic to hippocampal CA1 neurons and inhibited the expression of GluR1 and NR2B, excitatory glutamate receptor subunits. Furthermore, the combination of the two drugs caused greater damage than either drug alone. The results demonstrate that the short-term use of antiepileptic drugs damages neurons in the immature brain and that the combined use of antiepileptic drugs exacerbates damage. Our findings suggest that clinicians should consider the potential neurotoxic risk associated with the combined use of antiepileptic drugs in the treatment of seizure.

Efficacy of levetiracetam in electrical status epilepticus during sleep of children: a multicenter experience.

BACKGROUND: Electrical status epilepticus during sleep is characterized by epilepsy, a specific electroencephalographic pattern, and neuropsychological impairment. This study aims to evaluate the efficacy and safety of levetiracetam in treating children with electrical status epilepticus during sleep. METHODS: A multicenter, retrospective, open-label study enrolled 73 children (mean age: 8 years) affected by electrical status epilepticus during sleep. The efficacy was rated according to the seizure frequency and electroencephalography response. RESULTS: After a mean treatment period of 19 months (range: 6 to 24 months), 33 (63.5%) of 52 patients became seizure-free or had experienced remarkable reduction in seizures. The electrical status epilepticus of 41 (56.2%) of 73 patients disappeared off their electroencephalography. The electroencephalography efficacy of levetiracetam treatment was noted in the monotherapy (61.9%) and add-on (53.9%) groups. The clinical (67.7%) and electroencephalography (64.3%) response rates of the idiopathic group were better than those of the symptomatic group (57.1% and 45.2%, respectively). No patient discontinued the trial because of intolerability of side effects. CONCLUSIONS: Levetiracetam is effective in individuals with electrical status epilepticus during sleep with tolerable side effects.

Hospitalized patients with novel influenza A (H1N1) virus infection: Shanghai, June - July 2009.

BACKGROUND: From late May 2009, sporadic imported cases of novel influenza A (H1N1) were continuously confirmed in Shanghai, but there were few reports on its clinical presentation in China. The aim of the study was to investigate the demographic and clinical features of the laboratory-confirmed cases and the treatment with oseltamivir. METHOD: We performed a retrospective study in the Shanghai Public Health Clinical Center (SHAPHC), reviewing the medical records of the laboratory-confirmed patients derived from June 10 to July 20, 2009. RESULTS: A total of 156 cases were enrolled, of whom 152 had a history of recent travel. The mean age was 22.6 years and 89 cases (57.1%) were males. The most common symptoms were fever, cough, and sore throat, with children more likely to run a temperature above 38.5 degrees C than adults. The mean leucocyte count was 5.4 x 10(9)/L, the mean neutrophil count 3.2 x 10(9)/L and the mean lymphocyte count 1.4 x 10(9)/L. Other findings included a normal range or elevated level of C-reactive protein (CRP) and glutamic-pyruvic transaminase and a normal or decreased level of prealbumin; the levels of prealbumin and CRP were significantly lower in the children than in the adults. Fifty-two patients had abnormal chest CT results, with small unilateral or bilateral pulmonary infiltrates, axillary and mediastinal lymphadenopathy and local pleural thickening, while no cases showed symptoms of hypoxia. All the patients received oseltamivir and recovered without complications, but the duration of fever and virus shedding were significantly longer in the children than in the adults. CONCLUSIONS: Travel-related circulation may be an important reason for the H1N1 epidemic in the non-epidemic areas, and the virus caused mild respiratory symptoms. The infection in children was more severe in terms of prealbumin levels, temperature, the duration of fever and virus shedding. Oseltamivir was effective for H1N1, but more effective in the adults than in the children.

Pulmonary miliary tuberculosis and intestinal tuberculosis co-infected with AIDS.

Infections with human immunodeficiency virus (HIV) and Mycobacterium tuberculosis account for 25 million patients worldwide. Tuberculosis is the most common opportunistic infectious disease in HIV-infected subjects, and HIV infection is a high-risk factor for tuberculosis. The convergence of HIV and tuberculosis is a disaster practically unequalled in medical history. This is a rare case report on the topic of pulmonary miliary tuberculosis and intestinal tuberculosis with AIDS.
