RESUMEN
OBJECTIVE@#To determine the clinical efficacy of different manipulation in the treatment of cervical instability in young people, and to analyze the risk factors of relapse of cervical instability in young people.@*METHODS@#From March 2021 to June 2022, the clinical data of 120 young patients with cervical instability were retrospectively analyzed. According to the different treatment methods, they were divided into rotation group (60 cases, 3 cases of loss) and tendon group (60 cases, 5 cases of loss). There were 25 males and 32 females in rotation-traction manipulation group;age ranged from 22 to 44 years old with a median of 28 years old;course of disease ranged from 0.17 to 120 months with amedian of 22 months. There were 22 males and 33 females in tendon-regulating manipulation group;age ranged from 21 to 42 years old with a median of 27 years old;course of disease ranged from 0.23 to 180 months with a median of 24 months. Both groups were treated for 2 weeks, once every other day for 7 times, and were followed up for 1 year. The clinical efficacy of the two groups was evaluated, and the visual analogue scale (VAS), neck disability index (NDI) were observed before and after treatment. One year after the course of treatment, patients with effective treatment were followed up to make statistics on recurrence. Patients with recurrence were included in the recurrence group, while those without recurrence were included in the non-recurrence group. Factors that may affect symptom recurrence were analyzed, and univariate and multivariate Logistic regression analysis were performed.@*RESULTS@#The 13 patients who failed the treatment (4 cases in the rotation-traction manipulation group and 9 cases in the tendon-regulating manipulation group) were not followed up. All the 99 patients who were effective in treatment were followed up ranged from 303 to 406 days with a median of 359 days. No complications occurred in all patients. There were significant differences in VAS and NDI between the two groups after treatment and before treatment (P<0.05), and there were significant differences in VAS and NDI between the two groups after treatment (P<0.05). Ninety-nine patients achieved follow-up, 56 (56.57%) relapsed and 43 (43.43%) did not. Univariate correlation analysis showed that NDI index, the time spent at the desk every day, the time spent using electronic products every day and angular displacement of anterior flexion before treatment in the relapse group were significantly higher than those in the non-relapse group (P<0.05). Logistic regression analysis showed that the time spent at the desk every day [OR=2.447, 95%CI(1.255, 4.771)], the time spent using electronic products every day [OR=1.892, 95%CI(1.066, 3.358)] and the angular displacement of anterior flexion of the cervical before treatment [OR=1.246, 95%CI(1.045, 1.485) ]were the risk factors for relapse.@*CONCLUSION@#Both rotation-traction manipulation and tendon-regulating manipulation can effectively treat cervical instability in young people, and rotation-traction manipulation has more advantages than tendon-regulating manipulation in improving cervical pain and cervical dysfunction in patients. The time spent at the desk every day, the time spent using electronic products every day, and the increase of cervical flexion angle displacement will increase the risk of relapse in patients.

Objective To analyze the immunophenotypic characteristics of the patients with minimal residual disease (MRD) positive acute B lymphocytic leukemia (B-ALL). Methods The leukemia-associated immunophenotype (LAIP) of 106 cases with MRD positive B-ALL from Department of Hematology, Tianjin KingMed Diagnois Center between June 2014 and January 2016 were retrospectively analyzed. CD10, CD13/CD33, CD19, CD38, CD58, CD45 and other antibodies were used to analyze the MRD of B-ALL. Results All the patients were positive for CD19. CD34 was negatively or weakly positive expressed in 27 cases (25.4%). CD10 was negatively or weakly positive expressed in 23 cases (21.7%). CD10 was strongly positive in 24 cases (22.6%). Totally, CD10 was weakly or strongly expressed in 47 cases (44.3%). CD58 was strongly positive in 98 cases (92.5%). CD13/CD33 was positively or weakly positive expressed in 64 cases (60.4%). CD38 was negative or weakly expressed in 33 cases (31.1%). CD45 was negative in 21 cases (19.8%). 15 cases (14.1%) were positive for 6 types of LAIP; 30 (28.3%) cases were positive for 5 types of LAIP; 42 (39.6%) cases were positive for 4 types of LAIP; 13 (12.3%) cases were positive for 3 types of LAIP;5 cases (4.7%) were positive for 2 types of LAIP; only one case (0.9%) was positive for 1 type of LAIP. Conclusion The combination of CD58, CD13/CD33, CD10, CD38 and CD34 antibodies can distinguish the neoplastic blast/immature B lymphocytes from progenitor B cells.

RESUMEN
Objective To investigate the effect of Reduning Injection on Vero cells and suckling mice infected by EV71 virus and its mechanism in vitro and in vivo. Methods The anti-virus ability was exhibited in Vero cells which were infected by 33 TCID50 and 25 TCID50 titers of EV71 in vitro. Meanwhile, the antiviral activity in vivo was evaluated on suckling mice model, in which suckling mice were intraperitoneal injected with EV71 at 100 μL. After 2 h infection, Reduning Injection 2.60, 1.30, and 0.65 g/kg and ribavirin 10 mg/kg were followed for treatment. To further understand the antiviral effects of Reduning Injection, weigh of suckling mice, clinical symptoms, expression of IL-1β, IL-6, MCP-1, and TNF-α in skeletal muscle were recorded. Moreover, histological examination of skeletal muscle was examined. Results The results demonstrated that Reduning Injection 5.0 mg/mL could obviously inhibit Vero cells lesion induced by EV71 in vitro. Compared with the model group, suckling mouse model results showed the high and middle dose of Reduning Injection could reduce clinical manifestations scores, increase the weight and improve living conditions of model mice, decrease the expression of IL-1β, IL-6, TNF-α, and MCP-1 in skeletal muscle of suckling mice (P<0.05, 0.01). Histological damages in skeletal muscle were also alleviated with Reduning Injection treatment. Conclusion In a suckling mouse model, Reduning Injection can reduce mortality and obviously prolong the survival time of suckling mice caused by EV71 infection. It can alleviate clinical symptoms and growth inhibition caused by the EV71 virus. Inhibition of IL-1β, IL-6, TNF-α, and MCP-1 levels may be the important mechanism of Reduning Injection in the treatment of hand-foot-and-mouth disease.

RESUMEN
The present study was designed to evaluate the protective effects of Reduning injection against Enterovirus 71 (EV71) in Vero cells and in mice. The Vero cells were infected with 100 and 50 TCID50 (50% tissue culture infective dose) of EV71, respectively. The inhibition of Reduning injection on cytopathic effect (CPE) was detected. Meanwhile, a mouse model produced by intraperitoneal EV71-infection (10(6) TCID50), was used to investigate the protective effects of Reduning injection. The total survival rate, living time, daily survival rate, weight ratio, and score for symptoms were examined. The viral loads in Vero cells and muscle tissues were detected using real-time PCR. Finally, the content of cytokines was analyzed by ELISA. In the Vero cells, 2.5 mg crude drug·mL(-1) of Reduning injection inhibited CPE induced by EV71 infection. In the mice, 1.3 g crude drug·kg(-1) of Reduning injection rescued death triggered by infection, in comparison with model group. Moreover, the survival rate, weight ratio, and clinical scores were also improved. The viral RNA copies in the Vero cells and the mice muscle tissues were reduced. Besides, the steep EV71-induced accumulations of TNF-α and MCP-1 were decreased by Reduning injection. In conclusion, Reduning injection showed promising protective effects against EV71 in Vero cells and in mice.

<p><b>OBJECTIVE</b>IBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.</p><p><b>METHODS</b>Totally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.</p><p><b>RESULTS</b>After treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.</p><p><b>CONCLUSIONS</b>High sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.</p>

<p><b>OBJECTIVE</b>To investigate the intervention effect of thalidomide on paraquat-induced acute lung injury in mice and its mechanism.</p><p><b>METHODS</b>Male ICR mice were randomly allocated to negative control group (n = 30), thalidomide control group (n = 30), paraquat poisoning group (n = 30), 50 mg/kg thalidomide treatment group (n = 30), 100 mg/kg thalidomide treatment group (n = 30), and 150 mg/kg thalidomide treatment group (n = 30). The negative control group was intraperitoneally injected with the same volume of saline; the thalidomide control group was intraperitoneally injected with thalidomide (150 mg/kg); the paraquat poisoning group was intraperitoneally injected with diluted paraquat solution (22 mg/kg); each thalidomide treatment group was intraperitoneally injected with the same volume of paraquat solution (22 mg/kg) and was injected with thalidomide (50, 100, or 150 mg/kg) 1 h later. All mice were anesthetized and sacrificed at 1, 3, or 7 d after paraquat poisoning, and their lung tissue was collected. The levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in lung tissue were measured by double-antibody sandwich ELISA; the mRNA expression of nuclear factor-kappa B (NF-κB) was measured by RT-PCR; the protein expression of nuclear NF-kgr;B p65 was measured by Western blot. The pathological changes of lung tissue were observed under light microscope; the wet/dry ratio of the lung was calculated.</p><p><b>RESULTS</b>Compared with the negative control group, the paraquat poisoning group had significantly increased levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65 and wet/dry ratio of the lung (P < 0.05). Compared with the paraquat poisoning group, the thalidomide treatment groups had significantly decreased levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65 and wet/dry ratios of the lung (P < 0.05), and the 150 mg/kg thalidomide treatment group showed the most significant decrease in the levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65. The observation of pathological changes showed that the paraquat poisoning group had the most marked lung tissue damage at 3 d after poisoning, and the lung tissue damage was lessened in the thalidomide treatment groups.</p><p><b>CONCLUSION</b>Thalidomide can reduce paraquat-induced acute lung injury and lung edema. The mechanism may include inhibition of NF-κB activation and expression and downregulation of TNF-α, IL-1β, and IL-6.</p>

<p><b>OBJECTIVE</b>To clarify the expression and clinical significance of metastasis-associated in colon cancer 1 (MACC1) mRNA in hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>The expression and distribution of MACC1 were assessed by quantitative real-time polymerase chain reaction (RT-PCR) and immunohistochemical staining (IHC) in a cohort of hepatitis B virus-related HCC, including 138 in early (A), 96 in intermediate (B) and 120 in advanced stages (C). The association of MACC1 mRNA with disease progression and outcomes was analyzed by univariate and multivariate Cox analysis.</p><p><b>RESULTS</b>The intratumoral expressions of MACC1 mRNA in HCC stage I (0.001 76, range: 0.000 54 - 0.002 47), stage II (0.002 49, range: 0.000 55 - 0.006 78) and stage III (0.008 35, range: 0.006 86 - 0.009 88) were about 3-, 4- and 14-fold higher than that in the normal liver tissue (0.000 59, range: 0.000 57 - 0.000 60), respectively. Intratumoral expression of MACC1 mRNA increased with disease progression from stage I to stage III. HCC clinical staging classification, age, portal vein invasion and tumor differentiation were significantly associated with intratumoral high expression of MACC1 mRNA (All P < 0.05). Immunohistochemical staining showed that there was an increased MACC1 expression in cytoplasm of HCC cells and positive nuclear staining in some cases. Increased MACC1 mRNA expression could predict poor outcome and recurrence in stage A and B HCC postoperatively. The median tumor-free survival and total survival of patients with high MACC1 mRNA expression were 34.0 and 40 months, respectively, significantly lower than that in those with low expression (48.0 and 48.0 months) (all P < 0.01). Cox analysis showed that Child-Pugh grading and high expression of MACC1 mRNA were independent predictive factors, and high expression of MACC1 was an independent predictive factor affecting the tumor-free survival.</p><p><b>CONCLUSIONS</b>MACC1 mRNA up-regulation is a feature of disease progression in HCC. MACC1 mRNA expression in the HCC may become an independent predictive factor for recurrence and survival in postoperative HCC patients.</p>

<p><b>OBJECTIVE</b>To study the changes of body composition in females patients with human immunodeficiency virus (HIV)-related lipodystrophy (LD) syndrome (HIV-LD).</p><p><b>METHODS</b>Totally 25 female patients who were treated in our hospital from January 2002 to December 2009 were divided into LD group and non-LD group based on the existence of LD. All these patients were receiving highly active antiretroviral therapy (HAART). In addition, 12 healthy women were set as the controls. Total and regional body composition were measured by dual X-ray absorptiometry in all three groups.</p><p><b>RESULTS</b>The fat mass (FM) was correlated negatively with the duration of HAART (r=-0.431, P=0.029). Multiple linear regression analysis showed that FM had positive correlation with weight and negative correlation with lean mass (LM) (r = - 0. 973, P =0. 000). Total, trunk and leg FM were significantly lower in LD patients than that in controls (P <0.05).Meanwhile, total, trunk and leg bone mineral contents were statistically lower in LD patients than that in controls (P <0. 05). Lumbar bone mineral density of LD patients was lower than that of non-LD patients and controls, and there was significant difference between LD patients and controls (P = 0. 001). LM of LD patients was higher than that of non-LD patients but without statistical difference (P > 0. 05).</p><p><b>CONCLUSIONS</b>The peripheral and central FM and bone mineral contents remarkably decrease in female patients with HIV-LD. How-ever, HIV-LD patients tend to have higher LM than non-LD patients. .</p>

ObjectiveTo study the roles of cytokeratin-19 ( CK-19 ),vimentin,vascular endothelial growth factor-C( VEGF-C ),and cyclooxygenase-2 ( COX-2 ) played in the occurrence and development of Graves'disease(GD) and Hashimoto's thyroiditis(HT).Methods57 cases of GD and 58 cases of HT were enrolled in our study.Immunohistochemistry using SP method was carried out for assessment of the expression of CK-19,vimentin,VEGF-C,and COX-2 in the thyroid tissues.Results CK-19,VEGF-C,and COX-2 were expressed in the cytoplasm of thyroid follicular epithelial cells.Vimentin was expressed both in the mesenchyma and in the cytoplasm of thyroid follicular epithelial cells.The positive rates and expression intensities of CK-19 and VEGF-C in HT ( 86.2%,96.6% ) were significantly higher than those in GD ( 43.9%,56.1%,all P<0.05 ).The expression intensities of vimentin and COX-2 in GD ( 100.0%,93.1% ) were similar to those in HT ( 100.0%,91.2 % ),while the expression intensity of COX-2 in HT was significantly higher than that in GD( all P<0.05 ).The positive rates of CK-1 9 were much higher in type Ⅲ ( 81.3% ) of GD than in type Ⅰ ( 1 5.8% ) and type Ⅱ ( 40.9% ) of GD,and also higher in type P( 100% ) of HT than in type L(66.7% ) of HT.The positive rates of VEGF-C were much higher in type Ⅲ ( 87.5% ) of GD than in typeⅠ ( 36.8% ) and type Ⅱ ( 50.0%,all P < 0.05 ) of GD.ConclusionImmunohistochemical detection of the expression of CK-19,vimentin,VEGF-C,and COX-2 may carry clinical significance in revealing the occurrence and development as well as evaluating the prognosis of Graves'disease and Hashimoto's thyroiditis.
RESUMEN
<p><b>OBJECTIVES</b>Investigate the clinical efficacy of cryotherapy ablation treatment for advanced hepatocellular carcinoma. analyse the predictive factors of cryotherapy ablation treatment.</p><p><b>METHODS</b>There were 190 cases of hepatitis B-related HCC patients with advanced HCC from 2005 to 2008 in our hospital. By using clinical cohort method, they included cryoablation group (147 cases) and control group (43 cases), The median survival time and time to disease progression were compared. Evaluate clinical significance of age, gender, location of portal vein tumor thrombus, HBeAg, tumor histological grade, Child-Pugh classification, end-stage liver disease (MELD) score, advanced liver cancer prediction system (ALCPS) score and the Eastern Cooperative Oncology Group performance status (ECOG PS) score for predicting the efficacy of cryoablation. Group rates were compared with the x2 test, survival analysis by using Kaplan-Meier method, survival rates were compared by Log-rank analysis; multiple factor survival analysis by using Cox regression model.</p><p><b>RESULTS</b>Median survival time of cryoablation group and Control group was 7.5 (4.2 to 14.6) months and 3.2 (1.2 to 8.6) months, median TTP was 3.5 (2.5 to 4.5) months and 1.5 (1.0 to 3.5 months), the differences were statistically significant ( P less than 0.05 ). Median OS and TTP of advanced HCC patients who had Well-differentiated tumor, Child-pugh A-class and low score of MELD score, ALCPS score, ECOG PS score were significantly longer than the poorly differentiate, Child-Pugh B-class and the high those scores ( P less than 0.05). ECOG PS ( P less than 0.05, 95% CI 1.074 to 2.143) and ALCPS (P less than 0.05, 95% CI 1.005 to 2.121) were independent predictors for OS of advanced HCC.</p><p><b>CONCLUSION</b>Cryoablation treatment can prolong median OS and TTP of advanced HCC; ECOG PS and ALCPS are important predictors for survival time of advanced HCC.</p>
