The Journal of Practical Medicine 2016;32(18):3023-3026
Objective To explore the clinical value of tuberculous infection of T cells spot test (T-SPOT. TB)for diagnosing tuberculous pleurisy in immunocompromised patients. Methods The sensitivities of T-SPOT. TB,ADA, TB-DNA and tuberculosis antibodies to tuberculous pleurisy in 54 immunocompromised patients were compared.Among these patients,22 were retested by T-SPOT. TB after 2 months anti-tuberculosis treatment. Spot forming cells(SFCs) were compared before and after treatment. Results The diagnostic sensitivity of T-SPOT.TB (79.63%)was significantly higher than those of ADA (64.81%),TB-DNA (48.15%)and tuberculosis antibodies (55.56%) (P<0.05).22 patients were retested by the T-SPOT.TB after anti-TB treatment (2 months), the results showed that the positive rate of T-SPOT.TB was 90.91%,not significantly than previous tests (P<0.05).Both ESAT-6 and CFP-10 specific SFCs decreased significantly compared with those before anti-TB treatment (t=2.728 and 2.400,P<0.05 respectively). Conclusions T-SPOT.TB assay has satisfactory sensitivity and could be used in diagnosis of tuberculous pleurisy in immunocompromised patients.

International Journal of Laboratory Medicine 2016;37(13):1782-1783,1786
Objective To investigate the significance of serum cortisol and high‐sensitivity C‐reactive protein (hs‐CRP) test in elderly patients with neurasthenia .Methods A total of 160 elderly patients with neurasthenia in our hospital from January 2012 to June 2015 were selected as the research subjects (observation group) and 160 individuals undergoing the physical examination as the control group .The differences of serum BDNF ,CORT and hs‐CRP levels were compared between the two groups .The patients were divided into the obvious anxiety group and anxiety group according to the Hamilton Anxiety Scale (HAMD) .The differences of serum BDNF ,CORT and hs‐CRP levels were compared between these two groups ;meanwhile serum BDNF ,CORT and hs‐CRP levels after treatment in the patients with ideal curative effect were detected and the detection results were statistically compared with those before treatment .Results The BDNF and CORT levels in the observation group were significantly lower than those in the control group ,while the hs‐CRP level was significantly higher than that in the control group ;the BDNF and CORT levels in the obvious anxiety group were significantly lower than those in the anxiety group ,while the hs‐CRP level was significantly higher than that in the anxiety group ;the treatment outcome also showed that the BDNF and CORT levels after treatment in the patients obtai‐ning the ideal effect were significantly increased compared with the pre‐treatment levels ;while the hs‐CRP level was significantly decreased .Conclusion BDNF ,CORT and hs‐CRP are significantly correlated with neurasthenia occurrence and its severity ,which deserves to pay attention to in clinical practice .

Objective To observe the occurrence of vascular calcification in maintenance hemedialysis (MHD) patients. Method Sixty-nine MHD patients were enrolled in this study. Vascular calcification was evaluated by plain X-my films of chest, upper and lower extremites. Analyzed the relationship of vascular calcification and cardiovascular disease. Results Vascular calcification on X-ray films presented in 38 cases (55%). Of the 23 cases with calcification on arteries of extremites, 14 cases were found to have both intimal calcification and medial calcification. Patients with vascular calcification were older. Ischemic heart disease and cardiac failure appeared more frequently in the patients with vascular calcification. Conclusions Both intimal calcification and medial calcification are frequently found in the MHD patients. Vascular calcification is probablly associated with cardiovascular disease in MHD patients.

Journal of Applied Clinical Pediatrics 1986;0(02):-
Objective To observe the protection of Caspase inhibitor(zVAD-fmk,benzyloxycarbonyl-Val-Ala-Asp-fluoromethyl ketone) on neonatal rat with hypoxic-ischemic brain damage(HIBD).Methods Thirty-six neonatal rats,7 days old,were randomly divided into hypoxic-ischemic(HI) control group(A),zVAD-fmk treated group(B) and sham group(C).Before HI insult,a pan-Caspase inhibitor,zVAD-fmk or normal buffer solution was injected into the cerebral ventricle.The water content of cerebral hemisphere was measured and the percentage of apoptofic cells in hippocampal neurons was measured by Flow cytometer(Annexin V/PI) at 24 hours after HI insult.The effect on body weights(percentage of increased weight,WIP) and macroscopical changes(percentage of cortox and hippocampal dead neurons) were assessed at 14 days.Results Compared with group A,the water content of ischemic hemisphere and apoptosis percentage of hippocampal neurons in group B reduced significantly.The difference of percentage of increased weight at 14 days in group B was not significantly.Microscopic examination showed that cortox and hippocampus neural death rate in group B was proved significantly reduced compared with that in group A.Conclusion Intracerebral administration of zVAD-fmk has protective effects on hypoxic-ischemic brain damage in neonatal rat.

Objective To explore the use of enzyme-linked immunosorbent assay(ELISA) to test the serological BP180NC16A-ELISA index in patients with bullous pemphigoid (BP) and investigate the relationship of this index with disease monitoring and therapeutic guidance.Methods The serological BP180NC16a-ELISA index at different times was examined in twenty BP patients with ELISA kit and monitor changes of pre-treatment BP180NC16a-ELISA index condition score and efficacy relationship..Results Twenty patients tested by ELISA had 19 cases of positive patients with positive rate of 95.0% and one case negative with negative rate of 5.0%.After treatment,19 cases (19.60 ±4.63)d became stable,and condition score was (3.75 ± 1.37) points.After continued treatment (28.75 ± 6.11) d entering clinical remission,condition score was (2.25 ± 1.21)points.Compared with the score before treatment condition [(5.55 ± 1.61) points],differences were statistically significant (Z =-3.808,-3.965,P < 0.01),and clinical remission score below clinically stable condition (Z =-3.808,P <0.01).A total of 19 cases of patients' pre-ELISA treatment index were positive correlation with after treatment stable period and clinical remission period (rs =0.788,0.752,P < 0.01).Conclusions This study demonstrated that ELISA-detected BP180NCI6a-ELISA index was positively correlated with the BP disease severity and clinical course,which could be as the guideline to monitor and clinical treatment.

OBJECTIVETo study the possible mechanisms of chronic nonbacterial prostatitis (CNP) pain.
METHODSCNP models were established in male Wistar rats by the autoimmune method. Then the paw withdrawal threshold (PWT) was detected using the Von Frey filament, prostate pathological examination was conducted, the expressions of substance P (SP) and transient receptor potential vanilloid 1 (TRPV1) in the prostate tissue and L5-S2 spinal segments were determined by immunohistochemistry and their correlations were analyzed.
RESULTSCompared with the control group, the CNP model rats showed markedly decreased PWT (P < 0.05) and obvious inflammation in the prostate tissue, with significant differences in the scope of lesion and interstitial lymphocyte infiltration (P < 0.05). The expressions of SP and TRPV1 in the prostate and spinal cord dorsal horn L5-S2 were remarkably upregulated in the models as compared with the control rats (P < 0.05). However, the expression of SP in the prostate was not correlated with that in the spinal cord (r = 0.099, P = 0.338), nor was that of TRPV1 (r = 0.000, P = 0.5).
CONCLUSIONSP and TRPV1 were involved in the formation and persistence of pain in CNP rats through their upregulated expressions in the L5-S2 spinal segments.
