Objective To establish the normal reference ranges of peripheral blood CD4 and CD8 lymphocytes for the healthy population in Tianjin. Methods 366 samples were recruited from among local physical examination adults and their absolute and proportional values for the ranges of CD4 and CD8 lymphocytes were detected by quantitative flow cytometry with fluorescence labeled antibodies. Results Mean absolute values were (860.27?255.15) cells/?l for CD4 T cells,(671.60?371.39) cells/?l for CD8 T cells and (1.44?0.62) for CD4/CD8 ratio; and the proportional values were (37.05?7.42)% for CD4 T cells,(28.42?7.46)% for CD8 T cells. Our results showed no differences between gender and age on CD4 T cell counts among the healthy adult population in Tianjin. Conclusions There is difference in CD4 T lymphocyte counts in different areas.

Anti-HIV drugs still remain as the dominant role in the treatment of acquired immunodeficiency syndrome (AIDS), because no vaccine was found till today. Owing to structural diversity, few side effects, and abundant resources, natural compounds from traditional Chinese medicines and medicinal plants have unique advantages and good potential in prevention and treatment of AIDS. Many researchers have made great efforts in the field of anti-HIV natural compounds, and have found some natural compounds from traditional Chinese medicines with potent anti-HIV activities. These compounds can be classified into the following categories: alkaloids, coumarins, lignans, flavonoids, terpenoids, tannins, polysaccharides, proteins and peptides, and polyphenols. However, most of these researches are performed in vitro, and most natural compounds show weak anti-HIV activities and indefinite acting targets. In the paper, we reviewed some natural compounds derived from traditional Chinese medicines with potent anti-HIV activities in recent years.

Objective:To study the impact of smoking on C-reactive protein(CRP)concentration in gingival crevicular fluid(GCF) before and after initial treatment.Methods:18 smokers and 18 non-smokers with moderate or severe periodontal disease were recrui-ted into this study.The clinical indexes of periodontal examination of the patients were recorded,GCF samples of the patients were collected,CRP level in the samples was measured by radioimmunoassay balance method before and 4 weeks after initial treatment. Results:4 weeks after initial treatment,the clinical indexes and CRP concentration in GCF of the smoking group and non-smoking group were significantly lower than those before treatment(P <0.05),the changes of the smoking group were less than those of the non-smoking group(P <0.05).Conclusion:Smoking is an unfavorable factor of the initial periodontal therapy.

Objective To investigate the CT imaging features of urinary tract ceftriaxone-associated pseudolithiasis.Methods The CT imaging data of three patients with ceftriaxone-associated pseudolithiasis were collected from August,2008 to April,2012.Their data combined with related literatures were used to review CT imaging features of urinary tract pseudolithiasis.Those three patients,including 2 males and 1 female,were 9,21 and 55 years old,respectively.Ceftriaxone sodium was administrated to one patient due to appendicitis and the other two patients due to urinary tract infection.After ceftriaxone treatment,1 case began to have backache and abdominal pain on day 13,1 case presented backache with floc in the urine on day 2 and progressed to anuria,and the other one had cotton-like material in the urine on day 5.Urinary tract high density shadows were found in all patients by CT scan.The patient with anuria was treated with ureteroscopic lithotripsy and percutaneous nephrolithotomy.The other 2 cases were arranged to be followed up with CT scan.In those cases,the CT showed that the high density shadow in one patient disappeared 16 days after drug discontinuation.The high density shadow was significantly reduced 12 days after ceftriaxone withdrawal in the other one.However,no follow-up was performed afterwards.Results All the urinary tract ceftriaxone-associated pseudolithiasis presented the high density shadows on CT,with CT value 47-667 HU.The density of CT results is homogenic,except one ureteral stone.The pseudolithiasis,existed in kidney,ureter and bladder simultaneously,were found in two patients.And the other patient was found that the pseudolithiasis existed in both kidney and bladder.Two cases were accompanied with hydroureter and hydronephrosis and the other case were accompanied with cholecystolithiasis.The multiple renal pseudolithiasis was noticed in 2 cases,which exhibited the nodular shape.And one patient with hydronephrosis presented both sand-like and nodular stones.Ureteral pseudolithiasis was found in 1 case with 4 stones and the other one with 2 stones.In those pseudolithiasis,5 appeared column morphology and one showed nodular shape.The single nodular stone in bladder was found in one case.And the multiple bladder stones were found in 2 cases.Conclusions The CT imaging characters of urinary tract ceftriaxone-associated pseudolithiasis are high homogenic density shadows in multiple parts of bilateral urinary tracts.The ceftriaxone-associated pseudolithiasis is column shape in ureter and sand-like or nodular shape in kidney and bladder.

Objective To observe the expression of triggering receptor-1 on myeloid cells (TREM-1) of mice with acute lung injury (ALI) in oder to find out its regularity and significance in inflammatory response of or-ganisms. Method Thirty BALB/C mice were randomly(random number) divided into normal control group (n =6) and ALl group (n = 24). The models of ALI were made with intraperitonal injection of lipopolysaccharide (LPS) in dose of 10 mg/kg. Specimens from peripheral blood and lung tissue were collected 6 h, 12 h, 24 h and 48 h after LPS injected. The fluorescent real-time quantitative reverse transcriptiun-polymerase chain (RT-PCR) was used to detect TREM-1 mRNA, and ELISA was employed for detection of TREM-1 protein and TNF-α protein, and HE staining was made doe the pathological Smith lung score under light microscope. Analysis of variance was used for comparison of TREM-1 mRNA, TNF-α and Smith lung injury score between two groups. Spearman corre-lation analysis was made to find out the relationship among these three variables. Results The expressions of TREM-1 mRNA in lung tissue of ALI mice 6 h, 12 h, 24 h, and 48 hours after injection of LPS were 6.61±0.08,34.71±0.83, 61.85±14.05 and 56.46±8.89, respectively which were higher than that in control group (1.00±0.00, P = 0.017, 0.009, 0.002 and 0.003, respectively). The expressions of TREM-1 mRNA in blood were 14.01±3.24, 47.07±0.98, 8.18±0.43 and 8.06±0.05, respectively which were higher than that in normal control group (1.00±0.00, P = 0.010, 0.004, 0.011 and 0.011, respectively). The expression of TREM-1 rnRNA in tissue began to increase 6 hours after modeling and reached its peak 24 hours later, and expres-sion of TREM-1 mRNA in blood reached its peak after 12 hours. The levels of TREM-1 protein in lung tissue of ALl mice 6 h,12 h,24 h and 48 hours after LPS injected were 997.8±114.62, 1579.70±45.92, 1123.9±108.2 and 429.8±89.96 pg/mL, respectively which were higher than that of mice in control group (279.22±4.62 pg/mL, P = 0.024, 0.007, 0.011 and 0.04, respectively). The level of TREM- 1 protein reached the peak 12 hours after LPS injected, but it had no significant correlation with the expression of TREM-1 mRNA (P =0.14). The levels of TNF-α protein in lung tissue of ALI mice 6 h, 12 h, 24 h and 48 hours after LPS injection were 313.16±39.50, 491.91±96.65, 388.48±29.84 and 282.5±52.76 pg/mL, respectively which were sig-nificantly higher than that of mice in control group (256.6±28.31 pg,/mL, P = 0.037, 0.019, 0.032 and 0.043, respectively). The TNF-α concentration was positively correlated with TREM-1 levels in lung tissue and with Smith pathological score (r = 0.795, P = 0.001: r = 0.499, P = 0.034), but not with the expression of TREM-1 mRNA (P = 0.176). Conclusions The expression of TREM-1 mRNA in lung tissue of mice with ALI is elevated, and the expression of TREM-1 mRNA is related to the level of TNF-α and the severity of the ALI in in-flammatory responses in lung. The expressions of TREM- 1 gene are not consistent with the levels of TREM- 1 pro-tein, suggesting another new functional proteins involved in immune regulation.
