ABSTRACT

Primary hemifacial spasm is a motor disorder of facial muscles related to facial nerve. During the attack, the facial muscles present irregular and involuntary clonus, which can be induced or aggravated by emotional excitement, mental tension and random facial movement, seriously affecting daily work and life. The pathogenesis, diagnosis, differential diagnosis and treatment of the primary hemifacial spasm have been studied extensively in recent years. This article reviews the progress in these aspects.

ABSTRACT

Objective:To investigate the variation trend of peripheral blood CD34 + cells during the hematopoietic stem cell mobilization and its influence on the collection timing and results. Methods:The clinical data of 62 patients with hematologic diseases undergoing autologous peripheral blood hematopoietic stem cell mobilization from April 2012 to March 2017 in Shanxi Provincial Cancer Hospital were analyzed. Mobilization regimen used chemotherapy combined with granulocyte colony-stimulating factor (G-CSF) to monitor the number of white blood cells (WBC), mononuclear cells (MNC), CD34 + cells in peripheral blood and apheresis concentrates, and the correlation with CD34 + cells was analyzed. Furthermore, the receiver operating characteristic (ROC) curve was used to establish the threshold to start apheresis. Results:MNC (5.66±1.11)×10 8/kg and CD34 + cell count (2.15±1.20)×10 6/kg were obtained in 62 patients who received 136 times collection in total. The peak of peripheral blood CD34 + cells count appeared at day 4-5 after the treatment of G-CSF, and then it went down. CD34 + cell count in the product was correlated with the peripheral blood CD34 + cell count collected on the day ( r = 0.879, P < 0.01), and it was also correlated with the peripheral blood WBC and MNC collected on the day as well as MNC count in the product (all P < 0.05). Furthermore, the ROC curve analysis demonstrated that peripheral blood CD34 + cells count > 23/μl was the optimal threshold for stem cell collection on the day, 85.2% of patients reaching up to the threshold could be successfully collected at one time. Conclusions:The variation trend of peripheral blood CD34 + cell count can guide the best time of stem cell collection in clinic. Peripheral blood CD34 + cell count is the reliable index to predict CD34 + cells count in the products. Peripheral blood CD34 + cells count > 23/μl could be used as the collection threshold.

ABSTRACT

Objective:To investigate the etiology, clinical characteristics and outcome of severe pneumonia-associated hemophagocytic lymphohistiocytosis, and to analyze the risk factors for mortality.Methods:Clinical data of patients with severe pneumonia-associated hemophagocytic lymphohistiocytosis admitted to Shenzhen Children′s Hospital from February 2009 to February 2019 were retrospectively analyzed.The data included clinical characteristics, etiology, clinical manifestations, laboratory data, treatment and outcomes of the patients.The clinical characteristics and laboratory data of the survival group and the death group were compared by independent sample t-test. Results:(1) Clinical characteristics: the patients were aged from 3 months to 8 years and 7 months, including 15 males and 15 females.Severe pneumonia-associated hemophagocytic lymphohistiocytosis accounted for 2.74% (30/1 096 cases) of severe pneumonia in the same period.(2) Etiology: Mycoplasma pneumoniae infection was found in 8 cases (8/30 cases, 26.67%), virus infection in 7 cases (7/30 cases, 23.33%, including 5 cases with adenovirus infection, 1 case with EB virus infection, and 1 case with cytomegalovirus infection), Mycoplasma pneumoniae complicated with adenovirus infection in 4 cases (4/30 cases, 13.33%), bacterial infection in 3 cases (3/30 cases, 10%), and fungal infection in 2 cases, Mycobacterium tuberculosis infection in 1 case.The pathogens were not identified in 5 patients.(3) Clinical manifestations: fever and hepatomegaly were present in all patients.Besides, 86.67% (26/30)patients had fever duration more than 10 days, 83.33% (25/30 cases) patients had cough, 76.66% (23/30 cases) patients had splenomegaly, and 33.33% (10/30 cases) patients had nervous system symptoms.Laboratory data showed varying degrees of reduction of binary and ternary systems in 80.00%(24/30 cases) of the patients.Liver function impairment was found in half of the patients, and serum ferritin and lactate dehydrogenase levels were elevated in all patients.(4) The mortality rate was 30.00% (9/30 cases). The differences in age, hypertriglyceridemia and high serum ferritin levels between the survival and death groups were significant (all P<0.05). Conclusions:Severe pneumonia-associated hemophagocytic lymphohistiocytosis is a disease with a high mortality rate.Patients with Mycoplasma pneumoniae and adenovirus pneumonia are more likely to suffer from secondary hemophagocytic lymphohistiocytosis.Younger age, hypertriglyceridemia and high serum ferritin levels are indicative of poor prognosis.

ABSTRACT

Objective:To investigate the effect of infused CD34 + cell count on hematopoietic recovery and prognosis of non-Hodgkin lymphoma (NHL) patients after autologous peripheral blood hematopoietic stem cell transplantation (APBSCT). Methods:The data of 60 NHL patients who underwent APBSCT from May 2010 to May 2016 in the Affiliated Cancer Hospital of Shanxi Medical University was retrospectively analyzed, including 32 B-NHL patients and 28 T-NHL patients. The patients were grouped according to the receiver operating characteristic curve (ROC) threshold, and the hematopoietic reconstruction after transplantation was analyzed. The relationship between the infused CD34 + cell count and prognosis was analyzed. The prognostic factors were analyzed using univariate and multivariate analyses. Results:The CD34 + cell count threshold was determined to be 4.35×10 6/kg based on ROC. In CD34 + cell count≥ 4.35×10 6/kg group (20 cases) and CD34 + cell count < 4.35×10 6/kg group (40 cases), the granulocyte recovery time was (9.9±1.2) d and (12.5±3.7) d ( P = 0.031), and the platelet recovery time was (9.4±1.7) d and (13.8±2.9) d ( P = 0.012). The 3-year overall survival(OS) rates in CD34 + cell count ≥ 4.35×10 6/kg group and CD34 + cell count < 4.35×10 6/kg group were 85.0% and 55.0% ( P = 0.024), and the 3-year PFS rates were 85.0% and 57.5% ( P = 0.016). In B-NHL patients, the 3-year PFS rates in CD34 + cell count ≥ 4.35×10 6/kg group (11 cases) and CD34 + cell count < 4.35×10 6/kg group (21 cases) were 81.8% and 42.9% ( P = 0.037), respectively. In T-NHL patients, the 3-year OS rates in CD34 + cell count ≥ 4.35×10 6/kg group (9 cases) and CD34 + cell count < 4.35×10 6/kg group (19 cases) were 77.8% and 36.8% ( P = 0.049), respectively. Univariate survival analysis showed that the predictive factors of both OS and PFS included age > 60 years old, Ann Arbor stage Ⅲ-Ⅳ, international prognostic index (IPI) score > 2 and infused CD34 + cell count < 4.35×10 6/kg (all P < 0.05). Multivariate analysis showed that IPI score and infused CD34 + cell count were both independent predictive factors of PFS ( RR = 0.333, 95% CI 0.112-0.994, P = 0.049; RR = 0.190, 95% CI 0.047-0.773, P = 0.020), and IPI score was an independent predictive factor of OS ( RR = 0.095, 95% CI 0.011-0.837, P = 0.034). Conclusion:The infused CD34 + cell count affects the hematopoietic reconstruction time and component blood transfusion after APBSCT, and has certain predictive value for the prognosis of NHL patients.

ABSTRACT

Objective:To investigate the risk factors of non-obstructive gastric retention before endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliopancreatic disease.Methods:The matched case-control study included 109 patients with non-obstructive gastric retention before ERCP as the case group, and 218 patients without gastric retention as the control group. The patients′ medical records including comorbidities, preoperative medication and laboratory indicators were compared between the two groups. Multivariate conditional logistic regression models were subsequently used to determine the risk factors for non-obstructive gastric retention before ERCP.Results:Logistic regression revealed that the jaundice ( OR=12.359, P<0.001), opiates use ( OR=3.009, P=0.001), somatostatin use ( OR=2.445, P=0.033), fasting hyperglycemia ( OR=1.513, P=0.045), hypokalemia ( OR=4.634, P=0.001) and hyponatremia ( OR=1.805, P=0.023) were independent risk factors for non-obstructive gastric retention before ERCP in patients with biliopancreatic disease. Conclusion:Except for gastrointestinal obstruction, jaundice, opiates use, somatostatin use, fasting hyperglycemia, hypokalemia and hyponatremia are all risk factors for gastric retention in patients with biliopancreatic disease. Comprehensive evaluation and early intervention for patients showing these risk factors are needed.

ABSTRACT

Objective@#To explore the factors influencing the mobilization and collection of autologous peripheral blood stem cells.@*Methods@#The clinical data of 62 patients who received autologous peripheral blood hematopoietic stem cell mobilization in Shanxi Provincial Cancer Hospital from April 2012 to March 2017 were collected. The effects of age, gender, disease type, chemotherapy cycle, disease status, different schemes and the number of CD34+ cells in peripheral blood of patients 1 d before collection on the number of CD34+ cells and the success rate of CD34+ cells collection were analyzed. Measurement data were compared by one-way ANOVA and t test; count data were compared by χ 2 test; multivariate analysis was performed by multiple linear regression analysis.@*Results@#There were statistically significant differences in the number of CD34+ cells between patients with chemotherapy >6 cycles and ≤6 cycles [(2.6±1.3)×106/kg vs. (5.8±2.2)×106/kg; t = 5.221, P < 0.01], and the difference in the success rate of CD34+ cell collection between the two groups was statistically significant [68.8% (11/16) vs. 97.8% (45/46); χ2 = 8.396, P = 0.004]. The difference in the CD34+ cells yield was not statistical significance between male and female patients [(5.4±2.2)×106/kg vs. (4.5±2.8)×106/kg; t = 1.302, P = 0.198)], but the collection success rate in males was higher than that in females [97.6% (40/41) vs. 76.2% (16/21)], and the difference was statistically significant (χ 2 = 5.017, P = 0.025). The success rate of CD34+ cell collection in patients with ≥10/μl CD34+ cell in the peripheral blood was significantly higher than that in patients with < 10/μl CD34+ cells 1 d before the collection[97.9% (47/48) vs. 64.3% (9/14)], and the difference was statistically significant (χ 2 = 10.668, P = 0.001). The differences in CD34+ cells yield and collection success rate between patients with different age, disease type, disease status and mobilization regimen were not statistically significant (all P > 0.05). Multi-factor analysis showed that > 6 cycles chemotherapy before mobilization was the adverse factor affecting stem cell collection (b = -3.435, P < 0.01).@*Conclusions@#The effective mobilization and collection of autologous peripheral blood stem cells are related to the number of chemotherapy cycles before mobilization. The stem cell mobilization and collection should be conducted as soon as possible when the chemotherapy is ≤ 6 cycles and the patient reaches partial remission or above. In addition, peripheral blood CD34+ cell count should be monitored during mobilization. When the peripheral blood CD34+ cell count is > 10/μl, the collection could be started on the next day to obtain a better collection effect, so as to improve the success rate of collection.

ABSTRACT

Objective To observe the effect of different doses of HS6101 on the recovery of hematopoietic injury in ICR mice treated with cyclophosphamide (CTX). Methods Normal ICR mice were intraperitoneally injected with CTX at 100 mg/kg once a day for 3 consecutive days,and the mouse model of chemotherapy-induced hematopoietic injury was established. Three groups of mice (with 20 per group),were respectively injected with HS6101 at 0,9 or 27 μg subcutaneously at one hour before the first administration of CTX. The peripheral blood cell counts of the mice were observed once every 2 days. Hematopoietic progenitor cell colony counting and histopathological assessment of bone marrow cells were evaluated at 4 d and 9 d after the first administration of CTX. Results In ICR mice after chemotherapy with CTX,all doses of HS6101 significantly increased peripheral leukocytes and neutrophils (P<0.05),elevated the number of multilineage hematopoietic progenitor cell colonies of bone marrow,and stimulated the proliferation of bone marrow cells after CTX injury. Mice receiving 27 μg HS6101 were better than those of the other two groups. Conclusion HS6101 at 27 μg could significantly promote the recovery of hematopoiesis in ICR mice treated with CTX chemotherapy.

Objective To investigate the current work situation of senior clinical nurses to provide some advices for the nursing management .Methods The self-made questionnaires were adopted to investigate the work situation of 60 senior nurses for conduc-ting the descriptive analysis .Results The senior nurses′ satisfaction degrees to the professional self -identity ,the chief nurse′s scheduling ,the current work environment ,the approval by hospital and the emphasis degree by the department were not high .They thought that the suitable position for them was the office nurse and the second was the responsibility group leader .Whereas ,the un-dertaking key post at present was the responsibility group leader and the second was the office nurse .Conclusion Due to the partic-ularity of nursing work and the physiological and psychological change ,the senior nurses are unsuitable to the busy front -line work ;the senior clinical nurses have the rich clinical experience ,the stronger communicational and organizational coordination abili-ty ,and are more suitable for the posts of the office nurse and health education nurse ,and second is the post of responsibility group leader .

ABSTRACT

T-lymphoblastic lymphoma (T-LBL) is a rare form of non-Hodgkin lymphoma (NHL),which is biologically similar to T-acute lymphoblastic leukemia(ALL),and occurs most frequently in childhood and adolescence.T-LBL progresses fast.The treatment of LBL with conventional chemotherapy regimens for NHL has shown relatively low rates of complete remission and of disease-free survival.Now,it is reasonable to treat patients with LBL with the current ALL-type protocols,and hematopoietic stem cell transplantation may yield a more favorable overall survival (OS) in T-LBL patients,especial in relapsed or refractory LBL patients.

ABSTRACT

Objective To observe the expression of aquaporin-1(AQP1)in rats with acute lung injury induced by radiation,and discuss the protection of Tanreqing for rats with acute lung injury.Methods A total of 20 SD healthy rats were randomly assigned into 4 groups,including the comparison group,the radiation group(0.9% NaCl 0.2ml),the dexamethasne group(5mg/kg)and the Tanreqing group(0.67ml/kg).Strat intraperitoneal injection one day after radiotherapy,the rats were sacrificed after 7 days.The pathological changes of lung tissues were observed by HE stain.AQP1 expressions in lung tissues were detected by immunohistochemistry and RT-PCR test.Results Compared with the radiation group,there was an obvious amelioration in pathological injury of lung tissue in the dexamethasne and Tanreqing groups.AQP1 was increased significantly in comparison group(0.8006±0.05846),but AQP1 was decreased in the radiation group (0.4938±0.03477)(P<0.05),and AQP1 was increased after the Tanreqing and dexamethasne treatment(0.6492±0.03477,0.6664±0.03251) (P<0.05).Conclusion Tanreqing may have beneficial effects on radiationinduced lung injury by regulating AQP1 expression in the lungs of rats.
