Objective:To investigate the changes of T lymphocyte subsets and cytokines in children with he-patitis B virus(HBV)-associated glomerulonephritis (HBV-GN), and their relationship with HBV-DNA load.Methods:Forty-one children who was the first diagnosed with HBV-GN in Department of Pediatrics, the People′s Hospital of Gansu Province and Institute of Infectious Diseases, the First Hospital of Lanzhou University from September 2012 to September 2016 were collected as the objects(HBV-GN group). At the same time, the 40 patients with HBV infection (chronic HBV infection, normal liver and kidney function, normal 24-hour proteinuria quantitation, no hematuria under the microscope, no recent symptoms of cold and fever, etc.) were enrolled as the control group.The levels of T lymphocyte subset, tumor necrosis factor α(TNF-α), interferon-γ (IFN-γ), interleukin (IL)-2, IL-4, IL-6, IL-8 and IL-10 in the HBV-GN group and the control group were compared, and the relationship between HBV-DNA and cell factors was farther analyzed.Results:Compared with the control group, the proportions of CD3 + T, CD4 + T lymphocyte and CD4 + /CD8 + ratio decreased in the HBV-GN group(0.632±0.052 vs.0.692±0.047, 0.204±0.050 vs.0.466±0.038, 0.006±0.002 vs.0.017±0.003, t=1.025, 3.342, 5.234, all P<0.05), and the proportions of CD8 + T lymphocyte was significantly higher than that in the control group (0.411±0.023 vs.0.220±0.043, t=4.452, P<0.01). Besides, IL-2 and IFN-γ levels in the HBV-GN group were significantly lower than those in the control group[(23.36±2.55) ng/L vs.(36.33±1.24) ng/L, (19.20±2.18) ng/L vs.(61.25±2.08) ng/L, all P<0.05], and the serum levels of TNF-α, IL-4, IL-6, IL-8, and IL-10 were significantly higher than those in the control group[(19.60±1.46) ng/L vs.( 6.68±2.32) ng/L, (13.65±3.34) ng/L vs.(1.35±1.52) ng/L, (5.57±1.02) ng/L vs.(1.43±0.57) ng/L, (26.32±3.45) ng/L vs.(9.68±2.55) ng/L, (19.82±2.78) ng/L vs.(1.02±0.56) ng/L, all P<0.01]. Moreover, in HBV-GN patients, there was negative correlation between HBV-DNA load and IFN-γ, IL-2( r=-0.985, -0.943, all P<0.05), and positive relationship in HBV-DNA load with TNF-α, IL-4, IL-6, IL-8 and IL -10 levels( r=0.942, 0.966, 0.953, 0.944, 0.963, all P<0.05). Conclusions:There is an CD4 + /CD8 + imbalance and an abnormal level of cell factors in HBV-GN progression.In further HBV-GN treatment, HBV-DNA and the cell factors should be detected simultaneously to dynamically eva-luate the illness change and the clinical curative effect.

Objective To understand the clinical features of hepatic tuberculosis. Methods The clinical manifestations, laboratory findings, treatment, and prognosis of a case of hepatic tuberculosis were analyzed. Similar cases were identified from PubMed database during the period from 2013 to 2017 using search terms "Liver/Hepatology/Hepatic Tuberculosis". The clinical data of the identified patients with hepatic tuberculosis were reviewed and analyzed. Results The 16-year-old male patient presented with cough and abdominal distension. His sputum was positive for acid-fast bacillus. CT showed low-density spaceoccupying lesions. After anti-tuberculosis treatment, the lesion disappeared. Hepatic tuberculosis was finally considered, which was caused by disseminated tuberculosis. Literature search identified 63 similar cases. In summary, the 64 cases(containing this one)included 38 males and 26 females with age from 11 months to 77 years. Tuberculosis in other site or underlying disease was found in 39 cases. The main clinical manifestations were fever(51.6%), abdominal pain(50.0%), weight loss(31.2%), loss of appetite(25.0%), tiredness/weakness(21.9%), and nausea/vomiting(20.3%). Low-density space-occupying lesions were the main features on CT image. The diagnosis was confirmed by histopathological and/or bacteriological testing in 59 patients. Five patients were diagnosed after diagnostic anti-tuberculosis treatment was effective. Overall, 36 patients were cured, 19 improved, and 3 died.Conclusions The clinical symptoms of hepatic tuberculosis are atypical. Imaging combined with histopathological examination of the liver is the preferred method for diagnosis of hepatic tuberculosis. Anti-tuberculosis treatment and timely surgical treatment is usually effective with good outcomes.

Objective To understand the clinical features of splenic tuberculosis. Methods The clinical manifestations, laboratory tests, treatment outcomes of a case of splenic tuberculosis caused by hematogenous pulmonary tuberculosis were analyzed. Related literatures about splenic tuberculosis were also reviewed. Results The patient was a 19-year-old male. Cough, fever, night sweats, and weight loss were the main manifestations. Thoracoscopy revealed tuberculosis and imaging suggested splenic tuberculosis and tuberculosis in multiple body sites. Anti-tuberculosis treatment was effective in improving patient conditions. According to literature review, there are two types of splenic tuberculosis: primary splenic tuberculosis or as part of hematogenous pulmonary tuberculosis.The clinical manifestations of primary splenic tuberculosis are usually atypical. Immune deficiency is a significant risk factor of splenic tuberculosis. The main clinical manifestations of splenic tuberculosis are splenomegaly, fever, digestive system symptoms, and occasionally spontaneous splenic rupture (3/32). Most of the patients with splenic tuberculosis (28/32) were cured or improved by anti-tuberculosis treatment and/or splenectomy. Conclusions The onset of splenic tuberculosis is mostly insidious and clinical symptoms usually atypical. The diagnosis relies on radiographic findings, biopsy and pathological examination. Anti-tuberculosis and selective splenectomy are the effective treatment. The outcome of splenic tuberculosis is good in most patients.

Objective To explore the clinical value of Z score in assessing coronary artery lesions (CAL) of children with Kawasaki disease. Methods The clinical records of 102 children with Kawasaki disease from January 2012 to December 2016 in Gansu Provincial Hospital were retrospectively analyzed. The internal diameter of left main coronary artery (LMCA) and right coronary artery ( RCA) was measured by echocardiography (ECHO),and the incidence of CAL was preliminarily judged. The Z scores of LMCA and RCA were calculated on the basis of the coronary artery diameter,the age of the children and the body surface area,and the incidence of CAL was judged again. Results A total of 22 cases(21. 6%) of CAL were found in 102 cases by ECHO examination,of which 18 cases(17. 6%) of LMCA lesions,and 22 cases(21. 6%) of RCA lesions. A total of 33 cases(32. 4%) of CAL were found by calculating the Z score of coronary artery, of which 29 cases(28. 4%) of LMCA lesions and 33 cases(32. 4%) of RCA lesions. There was significant difference between two methods for determining LMCA lesions (χ2=3. 35,P<0. 05),and there was no sig-nificant difference between two methods for determining RCA lesions (χ2=3. 01,P>0. 05). Z score of coro-nary artery was more accurate to detect the CAL in Kawasaki disease,especially LMCA lesions. A large coro-nary artery aneurysm was found in the patients with the largest Z score by selective coronary angiography. Conclusion The Z score can be more conductive to assess the CAL in children with Kawasaki disease,and the higher the Z score,the more serious the CAL is.

Objective:To evaluate the accuracy of Cerec Bluecam and Cerec Omnicam with 3D printed resin models.Methods:A metal master model including 4 cylindrical metal preparations on the model base,respectively simulating the maxillary canine and the first molar preparations,was prepared.The right canine and the right first molar were respectively marked as A and B,and the left as C and D.The master model was scanned respectively by Cerec Bluecam and Cerec Omnicam for 10 times,10 digital models were genera-ted in Bluecam group and Omnnicam group respectively.Resin models were obtained by a 3D printer based on the digital models,the distance of AB,AC,BD and the diameter(d)of A were respectively measured.Statistical analysis was conducted by SPSS 13.0 soft-ware.Results:The distance of AB,AC,BD of master model and Bluecam group showed significant difference(P 0.05);the distance of AC,BD of master model and Omnicam group showed significant difference(P 0.05).All the distances of the Bluecam group and Omnicam group showed significant difference(P <0.05).Conclusion:The scanning accuracy of Cerec Bluecam is higher than that of Cerec Omnicam in a single preparation scanning.When the scanning area ex-tending,the scanning accuracy of Cerec Omnicam is higher than that of Cerec Bluecam.
