ABSTRACT

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells (T-bet) and GATA binding protein 3 (GATA3). MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective, double-blind and randomized control methods, the patients were randomized into three groups: kidney deficiency group, Qi and blood deficiency group, and control group. The three groups were respectively treated with Bushen Shengxue prescription granule, Yiqi Yangxue prescription granule, and Placebo (half the dose of Bushen Shengxue formula granules). In addition, all of them were given oral cyclosporin and androgen. The treatment lasted 6 months, with 3 months as a course. The blood routine indexes, T cell subsets, and fusion genes T-bet and GATA3 before and after treatment were analyzed, and the safety indexes were monitored. ResultDuring the observation, a total of 75 cases dropped out and 18 were rejected. Finally, 161 cases in the kidney deficiency group, 164 in the Qi and blood deficiency group, and 167 in the control group were included. After 6 months of treatment, the total effective rate was 98.8% (159/161) in the kidney deficiency group, which was higher than the 79.9% (131/164) in the Qi and blood deficiency group (χ2=30.135, P<0.01) and the 61.7% (103/167) in the control group (χ2=70.126, P<0.01). The total effective rate was higher in the Qi and blood deficiency group than in the control group (χ2=13.232, P<0.01). After treatment, the hemoglobin (HGB) content increased significantly in three groups (P<0.05) as compared with that before treatment, particularly the kidney deficiency group (P<0.01). After treatment, the white blood cell (WBC) count and platelet (PLT) count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group (P<0.01). There was no specific difference in neutrophils (ANC) after treatment among the three groups. At the same time point, the level of T helper type 1 (Th1) cells, Th1/Th2 ratio (P<0.05), level of CD4+, and CD4+/CD8+ ratio (P<0.05) were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19-, HLA/DR+, and CD25+ between the kidney deficiency group and the other two groups, but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group (P<0.05). ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism, inhibiting the activity of immune system, modulating T cell subsets, suppressing Th1 and CD4+, and promoting bone marrow hematopoiesis. Moreover, it is safe with little side effects, which is worthy of further promotion.

ABSTRACT

Objective To investigate the clinical features,diagnosis and treatment of medullary thyroid microcarcinoma (MTMC).Methods The clinical data of 14 patients with MTMC from Mar.2012 to Sep.2016 were retrospectively reviewed.All cases were treated with surgery and pathologically proved to be MTMC.Results All patients were sporadic MTMC.Calcitonin and CEA levels were measured before surgery in 11 patients.The median values were 81.61 (3.36-1187) pg/ml and 7.42 (0.81-90.75) ug/ml,respectively.All patients were followed up postoperatively.During a median follow-up of 24 months (8-63 months),no death happened.Regional lymph node metastasis occurred in 8 patients (57.14%),and lateral lymph node metastasis in 5 cases (35.71%).The rate of postoperative calcitonin abnormal was significantly higher in patients with lateral lymph node metastasis (P<0.01).6 cases (42.86%) had abnormal postoperative calcitonin,among whom 5 cases had preoperative baseline calcitonin level higher than 100 pg/ml.Patients having abnormal postoperative calcitonin suffered from higher calcitonin and CEA baseline (P<0.05).The tumor size was similar in two groups (P>0.05).Conclusions For patients with thyroid nodules,preoperative screen of calcitonin can effectively detect MTC.Patients with elevated CEA also need to exclude the possibility of MTC.Compared with tumor size,calcitonin baseline is more important to surgical options and postoperative outcomes.Lateral lymph node metastasis,baseline calcitonin >100 pg/ml indicates abnormal postoperative calcitonin.

ABSTRACT

OBJECTIVE@#This article summarizes the matters warranting consideration in adult cochlear implants before and after operation with different deafness causes and investigates the impact of etiological variables that affect hearing and speech ability rehabilitation after cochlear implantation.@*METHOD@#We retrospectively reviewed the preoperative data of 30 adults who have received cochlear implantation, switch on, and periodical post operative mapping. 'Nijmegen Cochlear Implant Questionnaire' was used for every patient during follow-up and test their hearing thresholds at one year after switched-on. The average score of every patient in the six aspects of questionnaire, along with the average hearing threshold, has been gathered.@*RESULT@#The average hearing threshold of every patient is lower than 35 dBHL. The average score of 28 patients is more than or equal to 75 in the basic sound perception, advanced sound perception as well as self-esteem. The average score of 26 patients is more than or equal to 75 in capacity for action. Besides, as for sociability and speech ability, the average score of 22 patients is more than or equal to 75.@*CONCLUSION@#Auditory perception can be greatly improved regardless of deafness causes, on the premise that appropriate candidate is selected. The primary disease should be brought under control before and after the operation. The influence of various causes to the language ability rehabilitation largely depends on the development of the language center at deafness onset. Self-esteem and social identity can be significantly enhanced after cochlear implantation in adult patients, particularly those with acquired deafness.

ABSTRACT

OBJECTIVE@#To investigate the expressions of high mobility group box B1 protein (HMGB1), matrix metalloproteinases-2(MMP-2) and matrix metalloproteinases-9 (MMP-9) in human laryngeal carcinoma and study their relationships with clinicopathological characteristics and prognosis.@*METHOD@#The expressions of HMGB1, MMP-2 and MMP-9 proteins were examined with the EnVision immunohistochemical method in 61 cases of laryngeal carcinoma. The expressions of HMGB1, MMP-2 and MMP-9 mRNA were detected by real-time quantitative RT-PCR method in 30 cases of laryngeal carcinoma.@*RESULT@#The positive expression rates of HMGB1, MMP-2 and MMP-9 proteins were significantly higher in laryngeal carcinoma than those in adjacent tissue (chi2=44.934, 49.923 and 36.054, P<0.01). The relative expression levels of HMGB1, MMP-2 and MMP-9 mRNA in laryngeal carcinoma were significantly higher than those in adjacent tissue (t=5.940, 7.005 and 7.664, P<0.01). The high level expression of HMGB1, MMP-2, MMP-9 proteins was closely associated with T stage, clinical stage and the status of lymph node metastasis (P<0.05 or P<0.01). There was a positive correlation between the expression of HMGB1 and MMP-9 protein (r=0.381, P<0.01). Univariate analysis indicated that the overall survival rate was lower in patients with a positive expression of HMGB1 and MMP-9 than those with negative expression (chi2= 4.974, 6.418, P<0.05). Multivariate analysis showed that HMGB1 was a risk predictor. A higher expression of HMGB1 was associated with a shorter survival time.@*CONCLUSION@#HMGB1, MMP-2 and MMP-9 play a role in invasion and metastasis of laryngeal carcinoma; Also there is a synergistic effect between HMGB1 and MMP-9; Moreover HMGB1 may be a independent prognostic factor.

ABSTRACT

OBJECTIVE@#This study was to investigate the expression and significance of Integrins subunits in laryngeal squamous cell carcinoma (LSCC).@*METHOD@#The expression of Integrins subunits was detected by cDNA microarray in 4 cases of primary LSCC tissues and corresponding adjacent normal tissues. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) were used to identify the different expression of Integrins subunits in 24 cases of primary LSCC tissues and corresponding adjacent normal tissues.@*RESULT@#A cDNA microarray analysis revealed significant changes in the expression of Integrins subunits, with IntegrinalphaV, Integrinbeta8 being up-regulated and Integrinalpha8 being down-regulated. The result of RT-PCR was consistent with that of cDNA microarray. The mRNA levels of IntegrinalphaV and Integrinbeta8 were significantly higher in LSCC tissues than that in corresponding adjacent normal tissues (1.0131 +/- 0.4780 vs 0.7591 +/- 0.4678 for IntegrinalphaV, P<0.05, 1.7362 +/- 1.3849 vs 1.2267 +/- 0.9363 for Integrinbeta8, P<0.05). The mRNA levels of Integrinalpha8 were significantly lower in LSCC tissues than that in corresponding adjacent normal tissues (0.2646 +/- 0.2622 vs 0.5457 +/- 0.3827, P<0.05).@*CONCLUSION@#The expression of IntegrinalphaV, Integrinbeta8, Integrinalpha8 were significantly up-regulated or down-regulated in laryngeal squamous cell carcinoma, which may relate to tumorigenesis and development of laryngeal squamous cell carcinoma.

ABSTRACT

OBJECTIVE@#To confirm the expression and distribution of aquaporin 5 (AQP5) in nasal polyps.@*METHOD@#AQP5 were studied in 20 samples nasal polyp without AR (Group NAR) and 16 samples with AR (Group AR) with immunochemistric staging and its integrated light intensity and its grey step.@*RESULT@#(1) Hematoxylin and eosin staining showed that there was obvious inflammation reaction, a large quantity of glands hyperplasia and acidophils soaked in nasal polyps, especially those with allergic rhinitis. (2) Immunofluorescence technique showed that the distribution of AQP5 in the two groups was in accordance with that in nasal polyps on the whole. AQP5 expressed mainly in the membrane and cytoplasm of the epithelium of the glands, ducts and cilia. (3) The statistical analysis of the immunohistochemical staining showed that the integrated light intensity of AQP5 in Group AR (0.1675+/-0.006536) was obviously higher than that in the Group NARs nasal polyps (0.09343+/-0.001816). There was statistical significance between the two groups (t = -12.00, P<0.01). (4) The statistical analysis of the immunohistochemical staining showed that the grey step of AQP5 in Group AR (175.6+/-2.471) was obviously lower than that in the Group NAR's nasal polyps (206.2+/-0.9649). There was statistical significance between the two groups (t=12.46, P<0.01).@*CONCLUSION@#AQP5 is expressed in nasal polyp. Combined with the research before, it was conferred that the hypersecretion of glands and its character has a relationship with the high expression of AQP5 in nasal polyps, and nasal polyp with different symptom has different mechanism.

ABSTRACT

Objective To investigate the outcome of powered laryngeal shaver for papilloma of the larynx in children by laryngeal endoscopy. Methods Thirty-nine children with papilloma of the larynx were treated by powered laryngeal shaver under a laryngeal endoscope. Twenty-seven of the patients who had an extensive tumor received radiofrequency to avoid hemorrhage and adhesion of the surgical surface. Results The mean operation time was (11.2?2.6) min, and the blood lose was less than 30 ml. Three months after the operation, 28 of the patients were fond of their voice quality. Among the 39 patients, 37 were followed up for 2-5 years, during which 3-year recurrence rate was 51% (19/37). In the children with primary patients, the rate of recurrence was 30% (3/10), and in those with recurrent tumor, the rate was 59% (16/27). Conclusions By using powered laryngeal shaver under a laryngeal endoscope, papilloma of the larynx can be accurately resected with low blood loss, short operation time and short hospital stay and confirmed effectivenss.
