Cytomegalovirus is a DNA virus that has the potential to latent-reactivation in human body with immune deficiency.CMV infection is usually asymptoatic in an immunocompetent host,but it may attack immunocompromised population.IL-10 is an important immunoregulatory cytokine,it can attenuate and terminate viral response by multiple immunosuppressive ways:affecting the expression of pro-inflammatory cytokines and chemokines,regulating antigen presenting cells,and restraining effector cell and NK cell responses.Currently,many researchers report that IL-10 has close relationtship with immunologic mechanism of cytomegalovirus in host.This paper reviews the biological effect of IL-10 and effect of IL-10 in cytomegalovirus infection.

Recently,an unconventional T cell population (collectively designated as Vδ2 -γδT cell ) has been characterized during the anti-cytomegalovirus immune response in all organ transplant recipients,neo-nates,and healthy individuals.These cytomegalovirus-induced Vδ2 -γδT cells undergo a dramatic and stable ex-pansion after cytomegalovirus infection,in a conventional adaptive way.Similarly,as cytomegalovirus-specific CD8 +αβT cells,they exhibit an effector/memory TEMRA phenotype and cytotoxic effect or functions.This paper reviews the researchs and reports about cytomegalovirus induced-Vδ2 -γδT cell,including its location,phe-notype,and activation,as well as its immunologic mechanism in cytomegalovirus infection,acute or chronic re-jection,and anti-cancer function.

Objective] To study Professor Wang Kungen's therapeutic principles in treating chronic constipation by data mining therapy. [Method]First, establish Wang Kungen's medical records database; then do data standardization and data mining. [Result]There are totally 207 cases that meet the demand. The major patterns of syndrome of CC in Professor Wang Kungen's medical records are as follows: gastrointestinal heat syndrome, stagnation of liver qi and spleen deficiency, Yin deficiency syndrome, Qi deficiency. The major prescriptions are as follows: Liumo Decoction, Xiao Yao San, Pi Yue Pill, Buzhong Yiqi decoction. There is close correlation between prescriptions and patterns as follows: gastrointestinal heat syndrome and Liumo Decoction; stagnation of liver qi and spleen deficiency and Xiao Yao San; Yin deficiency syndrome and Pi Yue Pill; Qi deficiency and Buzhong Yiqi decoction. There is close correlation between herbs as follows: rhizoma atractylodis macrocephalae and fructus arctii; rhizoma atractylodis macrocephalae and radix paeoniae alba; fructus cannabis and elecampane; rhizoma atractylodis and fuling; peach kernel and cortex moutan; semen raphani and fructus aurantii.[Conclusion] The evidence type of chronic constipation is relatively purging heat and keeping body fluid, soothing the liver and stomach, tonifying spleen and moistening intestines, tonifying Qi.

OBJECTIVE:To establish a HPLC method for the simultaneous determination of blood drug concentration of acetaminophen and phenacetin.METHODS:Diamonil C 18 was used as the chromatographic column,the mobile phase was methanol-water(45∶55),theophyllinum was used as internal standard,the detection wavelength was254nm and the column temperature was set at the room temperature.RESULTS:The minimum determination concentration of acetaminophen and phenacetin was5?g/ml,the calibration curve was linear in a range from5～25?g/ml;The recovery rate of both acetaminophen and phenacetin in this method was more than95%;both the intraday RSD and the interday RSD were less than4.0%.CONCLUSION:The method is rapid and accurate,which can satisfy the needs of the clinic blood drug concentration deter-mination of paracetamol and phenacetin.

Clinical, neuroimaging, and pathologic studies suggested that a variety of nonmotor symptoms, such as olfactory dysfunction, dysautonomia, and mood and sleep disorders, can precede the typic motor features of Parkinson disease (PD) by years and, perhaps, even decades. The period when these symptoms arise can be referred as the premotor phase of the disease. This paper reviewed the conception, clinical manifestation, pathology, diogose of the premotor phase of early Parkinson disease.

Objective:To evaluate the feasibility of two materials used as scaffolds in periodontal tissue engineering. Methods: Dog periodontal ligament cells cultured in vitro were collected and seeded on three-dimensional framework of cancellous bone matrix (CBM) or nano-HAp/collagen (nHAC) . The cell growth in the scaffolds was observed by cell counting and scanning electronic microscope. Results: Porous structure of the two materials and adhesion and eugonic growth of cells in the scaffolds were observed by scanning electronic microscope.The cell number was doubled in both scaffolds in 72 h culture. Conclusion: It may be feasible to use CBM or nHAC as the scaffolds for periodontal tissue engineering.

Objective To investigate the fetal haemolytic status when IgG antibody's efficiency of pregnant women was ≥1∶512 in blood group incompatibility. Methods We retrospectively analyzed the data of 6 pregnant women whose IgG antibody's efficiency were more than 1∶512 in blood group incompatibility. The levels of bilirubin, IgG antibody's efficiency and blood type in amniotic fluid from amniocentesis were examined. Umbilical blood bilirubin, blood type analysis and Coombs test of newborns were performed. Results Serum IgG antibody's efficiency of pregnant women did not correlate with the severity of haemolytic disease of newborn. Conclusions Fetal haemolytic disease can not be diagnosed only by serum IgG antibody's efficiency of pregnant women.

Objective To investigate and analyze the dwarf reasons for children in the area of Huai'an city,Jiangsu province.Methods A retrospective analysis of 92 cases of children with short stature in our hospital in recent 5 years had been made.Results The dwarf reasons for the 92 cases of undersized children were:lack of growth hormone (53.3％),physical sexual puberty delay (16.3％),hypothyroidism (9.8％),turner syndrome (7.6％),nanosoma essentialis (5.4％),familial short stature (4.3％),intrauterine growth retardation (2.2％)and glycogen storage disease type Ⅰ (1.1％).Conclusion The main dwarf reasons for children were growth hormone deficiency and physical sexual puberty delay,and medical treatment should be used as soon as possible.

Objective To study the clinical characteristics, diagnosis, treatment and prognosis of primary pulmonary peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods Two cases of primary pulmonary PTCL-NOS were studied and relevant literature were reviewed. Results Case 1 diagnosed as primary pulmonary PTCL-NOS was a 44 years old woman and disease progressed after GLD (Gem+L-OHP+DXM) chemotherapy regimen. At last, the patient died of respiratory failure after one month. Case 2 diagnosed as primary pulmonary PTCL-NOS was a 46 years old man and reach partial response after CHOP regimen, and still alive now.Conclusion Primary pulmonary PTCL-NOS is very rare. It is easy to be misdiagnosed due to non-specific clinical and imaging manifestations. Acquiring enough tissue specimens for pathologic examination is the key to a definitive diagnosis. At present, there is no standard chemotherapy regimen for these patients, the prognosis is relatively poor.

Objective To evaluate the value of MSCT and MRI in diagnosis of early postoperative complications of inguinal hernia repair (IHR).Methods Imaging and clinical data in 1 6 patients with early complications of IHR were analyzed retrospectively.Re-sults Among the complications,postoperative infection in 2 was found including incision infection in 1 and groin cellulitis in other 1. CT showed swelling abdominal wall and heterogeneous enhancement for incision infection,and inguinal mass,deep inguinal ring thickening,edema of residual sac with fluid and air collections for groin cellulitis.Seroma was found in 8,and CT and MRI demon-strated residual sac effusion,spermatic cord thickening and spermatic vascular tortuosity.Residual sac edema was found in 4,and CT and MRI showed thickening spermatic cord without effusion in residual sac or scrotum.Effusions between patch and anterior abdom-inal wall were detected by MRI in 2,one of which was accompanied by patch shrinking.Conclusion With specific clinical background for early complications of IHR,MSCT and MRI provide more anatomical information of inguinal region,which may contribute to di-agnosis and treatment of early postoperative complications.
