Objective: To explore the application value of T lymphocyte subsets combined with procalcitonin (PCT), C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR) and white blood cell count (WBC) in the auxiliary diagnosis and prognosis evaluation of sepsis. Methods: In a retrospective study, seventy-two patients with sepsis diagnosed and treated in Tianjin First Central Hospital from June 2018 to April 2021 were selected as the research objects, and included in the sepsis group were 46 males and 26 females, aged 68 (57.3, 80.3) years. In addition, 111 patients with local infection admitted to hospital during the same period were included in the local infection group, including 62 males and 49 females, aged 68 (51, 77) years. Sepsis patients were divided into survival group (43 cases) and death group (29 cases) according to the 28-day outcome. CD3⁺, CD4⁺, CD8⁺, CD4⁺/CD8⁺ ratio were detected by flow cytometry within 24 h after admission, PCT was detected by ELISA, CRP was detected by immunoturbidimetry, blood routine examination, blood lactic acid (Lac) and oxygen partial pressure (PO₂) were detected by instrumental method. Multivariate Logistic regression analysis was used to evaluate the correlation between each indicator and sepsis, and receiver operating characteristic curve (ROC) was drawn to evaluate the diagnostic value of each indicator for sepsis. Multivariate Logistic regression analysis and Kaplan Meier survival analysis were used to evaluate the prognostic value of each index for patients with sepsis. Results: Peripheral blood CD3⁺, CD4⁺, CD8⁺, CD4⁺/CD8⁺ ratio and PLT in sepsis group were significantly lower than those in local infection group(Z=-8.184,P<0.001;Z=-7.210,P<0.001;Z=-5.936,P<0.001;Z=-2.700,P=0.007;Z=-6.381,P<0.001); PCT, CRP, NLR and Lac levels were significantly higher than those in local infection group(Z=-8.262,P<0.001;Z=-3.094,P=0.002;Z=-9.004,P<0.001;Z=-4.770,P<0.001). Multivariate Logistic regression model showed that PCT, NLR, CD3⁺, CD8⁺, CD4⁺/CD8⁺ were independent risk factors for sepsis. According to ROC curve analysis, AUC of sepsis patients diagnosed by each indicator were 0.862, 0.894, 0.858, 0.760 and 0.618, respectively. The cut-off values were 3.075 ng/ml, 10.715, 44.935×10⁹/L, 27.463×10⁹/L and 0.750, respectively. The NLR sensitivity was 80.6%, and the CD3⁺ specificity was 94.6%. The AUC of combined detection of PCT and NLR was 0.947, sensitivity was 87.5% and specificity was 91.9%. The combined detection AUC of PCT, NLR, CD3⁺, CD4⁺/CD8⁺ was 0.958, the sensitivity and specificity were 90.3% and 91.0% respectively(P<0.001). PCT and Lac in death group were significantly higher than those in survival group(Z=-2.302,P=0.021;Z=-3.095,P=0.002);Peripheral blood CD4⁺/CD8⁺ levels were significantly lower than those in survival group(Z=-3.691,P<0.001),Multivariate Logistic regression model showed that CD4⁺/CD8⁺ ratio was an independent risk factor for 28 d mortality in patients with sepsis (P<0.001). The ROC curve showed that the AUC was 0.758, and the Youden index reached the maximum when the cut-off value was 1.27, the sensitivity and specificity were 79.3% and 60.5%, respectively. Compared with patients with CD4⁺/CD8⁺ ≥1.27, 28-day mortality was significantly increased in patients with CD4⁺/CD8⁺<1.27 (P=0.032). Conclusion: The combined detection of PCT, NLR, CD3⁺ and CD4⁺/CD8⁺ can improve the auxiliary diagnostic efficiency of sepsis, and the ratio of CD4⁺/CD8⁺ in peripheral blood may have certain predictive value for the prognosis of sepsis.

OBJECTIVETo explore the influence of rosa roxburghii tratt preparation on immune function of arseniasis patients caused by burning coal.

METHODSAccording to the diagnosis standard for endemic arseniasis(WS/T 211-2001), 62 cases of arseniasis patients who resided in endemic arseniasis area in Guizhou province were selected and divided stratified randomly into two groups: rosa roxburghii tratt juice treatment group and superoxide dismutase(SOD)-enriched rosa roxburghii tratt juice treatment group, with 31 patients in each group.Each patient took 120 ml/d rosa roxburghii tratt preparation or SOD-enriched rosa roxburghii tratt orally for one month. Another 30 healthy residents from a neighbour township 12 km away where arsenic was not prevalent were selected as controls. A 2 ml blood and 50 ml urine samples were collected from individuals and the urine arsenic contents, peripheral blood T-lymphocyte subsets (CD3(+), CD4(+), CD8(+) T cell), serum immunoglobulin (IgG, IgM, IgA) and complement (C3, C4) were detected. The differences between more than two groups on above indicators were compared. The correlations between urinary arsenic and immune parameters were analyzed.

RESULTSAmong the rosa roxburghii tratt juice group, SOD-enriched rosa roxburghii tratt juice before intervention group and the control group, the levels of urine arsenic were (76.55 ± 23.02) , (72.60 ± 25.91) and (26.33 ± 11.30) µg/g Cr respectively and IgG were (11.31 ± 1.68), (11.35 ± 1.94) and (9.23 ± 1.75) g/L respectively. The differences were statistically significant(F values were 82.01, 13.82, both P values < 0.05). After intervention with rosa roxburghii tratt preparation, the levels of urine arsenic were (53.21 ± 16.51) and (51.72 ± 17.70)µg/g Cr, both decreased than before intervention (t values were 5.80 and 3.78, both P values < 0.05). The levels of CD3(+) were (44.47 ± 7.14)%, (43.44 ± 6.61)% and (70.78 ± 5.26)%, CD4(+) were (29.87 ± 5.67)%, (29.42 ± 5.87)% and (46.08 ± 5.87)%, CD4(+)/CD8(+) were(1.25 ± 0.42), (1.22 ± 0.39) and (1.79 ± 0.26) and C4 were (0.13 ± 0.08), (0.13 ± 0.09) and (0.20 ± 0.11) g/L respectively among the two treatment group before intervention and the control group. The differences were significant (F values were 178.04, 76.71, 23.13 and 5.26, all P values < 0.05). After intervention, the levels of CD3(+) were (59.73 ± 7.38)% and (66.31 ± 7.57)%, CD4(+) were (34.00 ± 7.97)% and (39.11 ± 5.81)%, CD4(+)/CD8(+) were (1.41 ± 0.37) and(1.58 ± 0.26), all increased than before intervention(t values were 12.47, 25.18, 5.41, 10.47, 3.22 and 5.05, all P values < 0.05). The levels of urine arsenic and CD3(+), CD4(+), CD4(+)/CD8(+), C4 were inversely correlated correlation, while positive correlation existed between the level of urine arsenic and IgG(r values were -0.68, -0.56, -0.51, -0.43 and 0.36, all P values < 0.01).

CONCLUSIONSThe level of urinary arsenic level is closely related to immune function suppression in arseniasis patients caused by burning coal, rosa roxburghii tratt preparation can effectively improve immune function of arseniasis patients.

OBJECTIVETo observe the efficacy and safety of total glucosides of paeony capsule (TGPC) in patients with mild and moderate alopecia areata.

METHODSA total of 86 outpatients were randomly allocated into two groups of TGPC (treatment, 44 cases) and compound glycyrrhizin tablet (control, 42 cases). The treatment group was given oral TGPC, three times daily and 600 mg per time; the control group was given oral compound glycyrrhizin tablets, three times daily and 50 mg per time. In addition, both groups were given 10 mg of vitamin B(2) and tapped the bold patches with massage. The treatment course was three months for both groups. Peripheral blood T-cell subsets (CD3(+)CD4(+), CD3(+)CD8(+), Th, Ts, Th/Ts) of 10 patients randomly selected from each group respectively were tested before and after three months of treatment. The effectiveness and adverse reaction of all cases were observed each month. The safety was evaluated according to the incidence rate of adverse reaction.

RESULTSIn the treatment group, the cured and markedly effective rate was 36.36% (16/44), 50.00% (22/44) and 68.18% (30/44) at the end of first, second and third month of treatment, respectively, and the incidence rate of adverse reaction was 13.64% (6/44). In the control group, the cured and markedly effective rate was 38.10% (16/42), 57.14% (24/42) and 71.43% (30/42), respectively, and the incidence rate of adverse reaction was 16.67% (7/42). The cured and markedly effective rate and the incidence rate of adverse reaction were similar in both groups (P>0.05). TGPC and compound glycyrrhizin tablet can inhibit CD3(+)CD4(+) and CD3(+)CD8(+), and decrease the ratio of Th/Ts (P<0.05).

CONCLUSIONTGPC is effective and safe in the treatment of alopecia areata.

BACKGROUND: We developed a single-color multitarget flow cytometry (SM-FC) assay, a single-tube assay with graded mean fluorescence intensities (MFIs). We evaluated the repeatability of SM-FC, and its correlation with multicolor flow cytometry (MFC), to assess its application as a routine FC assay. METHODS: We selected CD19, CD3, CD4, and CD8 as antigen targets to analyze a lymphocyte subset. MFIs were graded by adjusting monoclonal antibody (mAb) volumes to detect several cell populations. Dimly labeled mAb was prepared by decreasing mAb volume and the optimum diluted volume was determined by serial dilution. SM-FC repeatability was analyzed 10 times in 2 normal controls. The correlation between SM-FC and MFC was evaluated in 20 normal and 23 patient samples. RESULTS: CV values (0.8-5.0% and 1.3-4.1% in samples 1 and 2, respectively) acquired by SM-FC with CD3-fluorescein alpha-isothyocyanate (FITC)dim+CD4-FITCbright and with CD19-FITCdim+CD3-FITCbright showed good repeatability, comparable to that acquired by MFC (1.6-3.7% and 1.0-4.8% in samples 1 and 2, respectively). Excellent correlation was observed between the 2 methods in the 20 normal samples (B cells, T cells, non-Thelper cells, and Thelper cells; r2=0.87, 0.97, 0.97, and 0.98, respectively; P<0.05). There were also linear relationships between SM-FC with CD19-FITCdim+CD3-FITCbright and CD8-PEdim+CD4-PEbright, and MFC, in the 23 patient samples (B cells, T cells, Tcytotoxic cells, and Thelper cells; r2> or =0.98, 0.99, 0.99, and 0.99, respectively; P<0.05). CONCLUSIONS: The multicolor, single-tube SM-FC technique is a potential alternative tool for identifying a lymphocyte subset.

OBJECTIVETo observe effect of oral scorpio and scolopendra powder on T-cell subsets in peripheral blood and intestine from rats with collagen induced arthritis (CIA).

METHOD60 rats were randomly divided into 6 groups: normal control group, model control group, low-dose scorpio and scolopendra group, middle-dose scorpio and scolopendra group, high-dose scorpio and scolopendra group, and type II collagen group. Rat's rheumatoid arthritis was induced by collagen II (C II). Level of T-cell subsets from peripheral blood and intestine was measured by flow cytometry.

RESULTCD4+ T cellular level was obviously increased (P < 0.05 or P < 0.01) or kept increased tendency in peripheral blood and intestine from the model group compared with that of the normal group, while the ratio of CD4+/CD8+ in intestine was obviously descent but the contrary in peripheral blood (P < 0.05 or P < 0.01). CD4+, CD8+ T cellular level in intestine were obviously descent and the ratio of CD4+ /CD8+ increased in all treated groups when compared with in the model group (P < 0.05 or P < 0.01). However, CD4+ T cellular level and the ratio of CD4+/CD8+ in peripheral blood were remarkablely decreased.

CONCLUSIONThe mechanism that scorpio and scolopendra could treat rat's rheumatoid arthritis may be regulating balance of T-lymphocyte subsets in peripheral blood and intestine.

BACKGROUNDSjögren syndrome (SS) is a systematic autoimmune disease, on which traditional therapeutic agents show limited effect. More effective agents with longer-lasting and fewer side effects are needed in the clinic. The aim of this study was to investigate the effects of Ganoderma lucindum spores (GLS) on sialoadenitis of nonobese diabetic (NOD) mice.

METHODSThirty-two female NOD mice were assigned randomly into 4 groups: low-dose GLS-treated (L-GLS) group and high-dose GLS-treated (H-GLS) group, a dexamethasone group, and a normal saline (NS) control group. Stimulated total saliva flow rate (STFR), area of lymphocytic infiltration in submandibular glands and ratios of CD4(+) and CD8(+) T lymphocytes and B lymphocytes in peripheral blood as well as apoptosis of these subsets and serum IgG level were tested after 10 weeks of treatments. Differences among the groups were analyzed by one-way analysis of variance (ANOVA), Student-Newman-Keuls Test (SNK) was used between each two groups and a P < 0.05 was considered statistically significant.

RESULTSSTFR of the high-dose GLS group increased significantly after a 10-week treatment compared with those of the NS control group (P < 0.05). The incidence of sialoadenitis in GLS-treated NOD mice groups showed no significant difference compared with the control group (P > 0.05), but the area of lymphocytic foci in both the H-GLS and L-GLS groups decreased significantly to 50% of the NS control group (P < 0.05); the ratio of CD4(+)/CD8(+) T lymphocytes and apoptosis of B lymphocytes of NOD mice with sialoadenitis were less and apoptosis of CD4(+) and CD8(+) T lymphocytes were significantly increased compared with the control group (P < 0.05). After pretreatment with H-GLS before sialoadenitis onset, the ratio of CD4(+)/CD8(+) T lymphocyte and the serum IgG levels of NOD mice decreased significantly (P < 0.05).

CONCLUSIONSPretreatment with H-GLS can relieve symptoms of sialoadenitis in NOD mice. GLS has some protective effects on sialoadenitis in NOD mice through increasing STFR and decreasing the area of lymphocytic foci by regulating the ratio of CD4(+)/CD8(+) T and apoptosis of B lymphocytes.

OBJECTIVETo explore and compare the clinical effects of three immuno-potentiators and their influence on immune function in preventing and treating recurrent respiratory tract infection (RRI).

METHODSSeventy-two children with RRT were assigned to three groups, the 23 patients in the M group treated with milkvetch extract oral liquid, the 23 in the P group treated by P-transfer factor and the 26 in the U group treated by Utilins injection. Clinical effect was compared among three groups after treatment, and changes of T cell subgroups as well as immune antibodies were detected before and after treatment.

RESULTSThe markedly effective rate in the M, P, and U group was 69.6%, 65.2%, and 73.0% respectively, and the total effective rate 87.0%, 82.6%, and 92.3%, showing an insignificant difference among them (all P>0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ rose obviously in the three groups (all P<0.05); levels of CD8+ in the M group and the P group lowered significantly (P<0.05, P<0.01), but with no significant difference among three groups in the changes of T cell subgroups (all P>0.05). Serum levels of IgG in all the three groups, IgA in the P group and the M group, and IgM in the M group and the U group rose significantly (P<0.05 or P<0.01), with statistical difference presented in comparing of IgA level in the P group with that in the other two groups (P<0.01).

CONCLUSIONThe clinical effects and the outcomes of immunological indexes' changing are similar in RRI patients treated by the three immuno-potentiators. They all can enhance the immunological function of the organism, strengthen the disease-resistant ability of patients, and reduce the incidence of RRI. Among them, the milkvetch extract oral liquid is worthy of spreading due to its lower cost, simple administration, exemption from painful injection, and good compliance.
