ABSTRACT
【Objective】 To study the current situation of apheresis platelets collection in various regions of Gansu province by comparing and analyzing relevant data from blood stations in 14 prefecture-level cities of Gansu province. 【Methods】 The units of collected platelets and rate of double-dose collection in 13 regional blood stations and 1 provincial blood center from 2016 to 2020, as well as the clinical supply and demand was statistically analyzed. 【Results】 From 2016 to 2020, the total units of platelets collected by 13 blood stations and 1 blood center in Gansu increased from 11 255 U to 15 270 U, with the increase rate at 35.7% in 5 years, and mainly were collected by the provincial blood center (74.57%, 50 253/ 67 392). Although the rate of double-dose collection in the province showed a steady upward trend, only 3 blood stations realized annual double-dose collection more than 20%. There was still a gap of about 10% between supply and clinical needs. 【Conclusion】 Although the number of platelet collections and units in each blood station in Gansu is on the rise in general, the units collected varies in each blood station. Therefore, further measures need to be taken from the aspects of publicity, recruitment, optimizing the collection process, improving the rate of double-dose collection, retention of regular blood donors and regional coordination to increase the collection units, narrow down the regional gap and ensure the balance between supply and demand.
ABSTRACT
Objective:To explore the clinical significance of different metabolic parameters measured by 18F-fluorodeoxyglucose (FDG) PET/CT in predicting the effectiveness of chemotherapy in advanced lung adenocarcinoma patients. Methods:A set of metabolic parameters of PET/CT and clinical characteristics which were detected from 127 patients (70 males, 57 females, age (56.8±10.1) years) with advanced lung adenocarcinoma treated with at least two cycles of chemotherapy in Hainan Cancer Hospital between August 2017 and June 2019 were retrospectively analyzed. The effects of those parameters on patients′ survival were analyzed by receiver operating characteristic (ROC) curve, Kaplan-Meier method (log-rank test) and Cox proportional hazards model.Results:Maximum standardized uptake value (SUV max), metabolic tumor volume 30% (MTV 30), and total lesion glycolysis 30% (TLG 30) had larger areas under the curve (0.581, 0.606 and 0.693 respectively) compared with other imaging parameters, and the optimal cut-off values were 10.12, 20.21 cm 3 and 81.25 g respectively. Kaplan-Meier univariate and Cox analyses synergistically showed that clinical stage (hazard ratio ( HR)=0.293(95% CI: 0.190-0.451), P<0.001), smoking ( HR=0.732(95% CI: 0.605-0.885), P=0.001), and MTV 30 ( HR=1.555(95% CI: 1.078-2.242), P=0.018) had significant predictive value for progression-free survival (PFS). Stratified analysis showed that smoking and MTV 30>20.21 cm 3 were independent prognostic factors for poor PFS in patients with advanced lung adenocarcinoma receiving chemotherapy ( HR=0.738(95% CI: 0.611-0.893), P=0.002; HR=1.502(95% CI: 1.037-2.177), P=0.032). Conclusions:Clinical stage, smoking and MTV 30 are independent prognostic factors of PFS in patients with advanced lung adenocarcinoma receiving chemotherapy. MTV 30≤20.21 cm 3 is expected to be an image biomarker for predicting survival and selecting patients with advanced lung adenocarcinoma who are more likely to benefit from chemotherapy.
ABSTRACT
Objective:To explore the debridement effectiveness of infected bone tissue of chronic hematogenous osteomyelitis in the lower extremities under the guidance of 99mTc-MDP SPECT/CT fused images. Methods:A retrospective case series analysis was conducted on 21 patients with chronic hematogenous osteomyelitis in the lower extremities treated at Southwest Hospital of Army Medical University from May 2017 to June 2020. There were 8 males and 13 females, with the age range of 10-62 years [23(18, 37)years]. The tibial infections were found in 16 patients, and femoral infections in 5 patients. The duration of bone infection was 4-480 months [120(42, 228)months]. According to the Cierny-Mader anatomico-physiological system, 4 patients were classified as type I, 14 as type III, 3 as type IV; 18 patients were classified as type A and 3 as type B. Intraoperative debridement of infected bone tissue was operated at stage I on the region of interest (ROI) where the isocontour(ISO) value was between 30%-40%, using the preoperative 99mTc-MDP SPECT/CT fused images as the reference. The stage II bone defect reconstruction was based on autologous and / or allogeneic bone. To observe the frequency of operations regarding bone infection control in stage I. The preoperative white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), intraoperative bacterial culture and pathological examination were compared at stages I and II. The skin redness and swellings, pain, sinus tract in the infected limbs, and ossification of grafted bones in the original bone defect part were observed at stage II. The accuracy rate between ISO value in the region of interest (ROI) and set ISO figure was checked. The difference of longitudinal length of the bone debridement area in ROI area with the actual bone debridement area was observed under the coronal position. Results:All patients were followed up for 6-36 months [11(9, 29)months] after stage II operation. All of the 21 patients had undergone operations of infection control with an average number of 1.04 times in stage I. 1 patient's intraoperative frozen section indicated that neutrophils were>5/HP. The bone graft at stage II had been completed after another debridement. Comparison of preoperative inflammatory markers at stages I and II: the WBC was decreased from (5.9±1.6)×10 9/L to (5.4±1.5)×10 9/L ( P>0.05), the ESR decreased from 9(5, 26)mm/h to 4(2, 10)mm/h ( P<0.05), and the CRP decreased from 2.8(2.3, 7.7)mg/L to 2.3(1.4, 3.0)mg/L ( P>0.05). The results of bacterial culture of tissue at stage I were positive in 12 patients and negative in 9 patients. The pathological examination indicated neutrophils and lymphocyte infiltration. The results of bacterial culture of tissue at stage II were all negative. A modicum of plasmacyte and lymphocyte infiltration and the neutrophils (<5 per/Hp) had been found in the intraoperative frozen section and pathological examination. No redness, swelling or sinus tract was found in the skin after stage II surgery and ossification of grafted bone was good. The accuracy rate between ISO value in the ROI and set ISO figure was 90.5%. The comparison between longitudinal debridement scope of ROI [(86.8±31.1)mm] and actual bone tissue debridement scope [(86.0±31.3)mm] at stage I showed no significant difference ( P>0.05). Conclusions:99mTc-MDP SPECT/CT fused images can be used as an effective means to define the debridement scope of infected bone tissue preoperatively. The method can not only avoid excessive debridement, but also improve the cure rate of hematogenous osteomyelitis in the lower extremities.
ABSTRACT
Objective Alzheimer's disease (AD) is the most common cause of dementia. The pathophysiology of the disease mostly remains unearthed, thereby challenging drug development for AD. This study aims to screen high throughput gene expression data using weighted co-expression network analysis (WGCNA) to explore the potential therapeutic targets.Methods The dataset of GSE36980 was obtained from the Gene Expression Omnibus (GEO) database. Normalization, quality control, filtration, and soft-threshold calculation were carried out before clustering the co-expressed genes into different modules. Furthermore, the correlation coefficients between the modules and clinical traits were computed to identify the key modules. Gene ontology and pathway enrichment analyses were performed on the key module genes. The STRING database was used to construct the protein-protein interaction (PPI) networks, which were further analyzed by Cytoscape app (MCODE). Finally, validation of hub genes was conducted by external GEO datasets of GSE 1297 and GSE 28146.Results Co-expressed genes were clustered into 27 modules, among which 6 modules were identified as the key module relating to AD occurrence. These key modules are primarily involved in chemical synaptic transmission (GO:0007268), the tricarboxylic acid (TCA) cycle and respiratory electron transport (R-HSA-1428517).

ABSTRACT
Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.
ABSTRACT
OBJECTIVE To explore the effect of connexin (Cx) 40-formed gap junctional intercellular communication (GJIC) on Photofrin- photodynamic therapy (PDT) phototoxicity in Cx40- transfected HeLa cells and its potential mechanisms. METHODS HeLa cell line stably transfected to express Cx40 was seeded at high and low cell density, respectively, to assess in vitro photosensitivity using CCK8 assay. Western blot assay was performed to detect the expression of Cx40. The intracellular ROS and Ca2 +concentrations were determined using flow cytometer. 4-HNE and ceramide were measured using ELISA assay. RESULTS Cx40-composed GJ formation at high density enhances the phototoxicity of Photofrin-PDT. When the Cx40 is not expressed or Cx40 channels are blocked, the phototoxicity in high-density cultures substantially reduces, indicating that the enhanced PDT phototoxicity at high density is mediated by Cx40-composed GJIC. The GJIC-mediated increase in PDT phototoxicity was associated with ROS and calcium-mediated stress signaling pathways. CONCLUSION The work uniquely presents the ability of Cx40-composed GJIC to enhance the sensitivity of malignant cells to PDT, and indicates that mainte?nance or increase of Cx40-formed GJIC may be a profitable strategy towards the enhancement of PDT therapeutic efficiency.
ABSTRACT
Objective@#To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO.@*Methods@#Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×109/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×109/L.@*Results@#A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×109/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×109/L) at 4th week, 8th week and 12th week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×109/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild.@*Conclusion@#Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

ABSTRACT
To establish the integration of Alzheimer's disease(AD) and blood stasis syndrome tree shrew model. Panax notoginseng saponins (PNS) was used to intervene the model to testify the stability of the model. The level of blood stasis of each group in the tree shrew model was evaluated by analyzing five traditional Chinese medicine(TCM) characterizations, four blood coagulation indexes, plasma nitric oxide (NO) level, plasma superoxide dismutase (SOD) level in each group. Hematoxylin and eosin(HE) staining was used to observe the morphological changes of brain hippocampal neuron cell of each group. Immunohistochemical staining was used to assay the ChAT and SYP levels in brain hippocampus of each group.The blood stasis characterization of the integration of disease and syndrome group was more obvious than the AD group, and that of the drug administration group was lower than that of the integration of disease and syndrome group. Aβ1-42, APP, P-Tau, ChAT and SYP level of AD group were lower than those in the blank group, which were further reduced in the model of integration of disease and syndrome. However, the administration of PNS relieved the reduction, indicating that the AD and blood stasis integration syndrome tree shrew model is stable.

ABSTRACT
OBJECTIVE:To study in vitro effects of tanshinoneⅡA to reverse multiple drug resistance. METHODS:MCF-7/ADM cells and A549/DDP cells were cultured with 0 [20 mg/L doxorubicin(ADM)or cisplatin(DDP),negative control],5 mg/ml tanshinone ⅡA(combined with 20 mg/L ADM or DDP)for 24 and 48 h. Then MTT method was used to determine cell viability, and polymerase chain reaction(PCR)was adopted to detect mRNA expressions of cell cycle control protein CDC25A and cell cy-clin dependent kinase (CKD2). RESULTS:Compared to the negative control,after MCF-7/ADM cells and A549/DDP cells were cultured with tanshinone ⅡA for 24 and 48 h,cell viability was weaker,also were mRNA expressions of CDC25A and CKD2. There were statistical differences(P<0.01). CONCLUSIONS:Tanshinone ⅡA combined with ADM or DDP can inhibit the viabili-ty of cell line MCF-7/ADM and cell line A549/DDP,decrease expression of CDC25A,CKD2 mRNA in cells and reverse multiple drug resistance in malignant tumors.
ABSTRACT
Objective To discuss the therapeutic effect of transcatheter arterial embolization using hardening agent combined with oral propranolol in treating giant hemangioma at maxillofacial region in infants. Methods During the period from October 2013 to December 2014 at Imaging Center of Anhui Provincial Children's Hospital, transcatheter arterial embolization using hardening agent combined with oral propranolol was employed in a total of 27 infants with giant hemangioma at maxillofacial region. The age of the infants ranged from 2 months to 22 months (mean 5.9 months) and the body weight was 4.5-10 kg with a mean of 6.32 kg. Angiography via femoral artery was performed, which was followed by super-selective catheterization of hemangioma-feeding artery, and then pingyangmycin lipiodol emulsion was injected into the hemangiomas with subsequent injection of PVA particles to obstruct the hemangioma-feeding artery. After the embolization treatment, the patient received oral propranolol for 3-6 months. Results All the infant patients were followed up for 3-6 months. Clinical examination and ultrasonography indicated that the hemangioma was cured in 20 infants (75%) and the therapeutic result was effective in 7 infants (25%). Skin necrosis at hemangiomas site was observed in 2 infants (7.5%), which was cured after symptomatic treatment. No serious complications such as pulmonary embolism, cerebral embolism occurred, and no recurrence was observed. Conclusion For the treatment of giant hemangioma at maxillofacial region in infants, transcatheter arterial embolization using hardening agent combined with oral propranolol is minimally invasive, quickly effective and highly safe;and this treatment leaves no scar formation in most cases. Therefore, this technique is worthy of clinical application.

Objective To investigate the influence of ulinastatin combined with Xue Bi Jing injection therapy on serum interleukin interleukin-8 (IL)-8 and γ-interferon (γ-IFN) of patients with severe acute pancreatitis(SAP).Methods Seventy patients with SAP were randomly divided into the control group(n=35) and research group (n =35).Patients in the control group were given ulinastatin on the foundation of traditional treatment,and in research group were given Xue Bi Jing injection on the foundation of treatment of the control group.The rehef time of abdominal distension and abdominal pain,time of serum amylase (sAMY) and white blood cell count(WBC) returned to normal were recorded.The IL-8 and γ-IFN of before and after treatment of the two groups were measured.Results The relief time of abdominal distension,abdominal pain,times of serum amylase,WBC returned to normal in treatment group were (4.1 ± 1.5) d,(4.2 ± 1.9) d,(5.2 ± 1.4) d,(6.5 ± 1.9) d respectively,significantly shorter than the control group((6.2±2.4) d,(6.5±2.2) d,(6.8±2.5) d,(8.9±2.5) d;t=5.468,5.747,4.354,4.647;P＜0.05).The IL-8 and IFN-γ at the 3rd.day and 7th day after treatment of the two groups decreased obviously,and those in the observation group were significantly lower than the control group (P ＜ 0.05).Conclusion Ulinastatin combined with Xue Bi Jing injection therapy can conspicuously reduce the IL-8 and γ-IFN levels in patients with severe acute pancreatitis and alleviate the clinical symptom.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Modified Dachengqi Decoction (MDD) as whole course therapy on mediators of inflammation in severe acute pancreatitis (SAP) model rats, and to compare interventional advantages over intestinal mucosal barrier (IMB) of SAP rats between whole course therapy of MDD and early stage therapy of MDD.</p><p><b>METHODS</b>Totally 190 SD rats were divided into five groups according to random digit table, i.e., the sham-operation group, the model group, the octreotide (OT) group, the early stage MDD treatment group, the whole course MDD treatment group, 38 in each group. SAP models were established with retrograde injection of 5% sodium taurocholate into the pancreaticobiliary duct. Three hours after modeling normal saline (NS) was administered to rats in the sham-operation group and the model group by gastrogavage, once per 12 h.1.35 µg/100 g OT was subcutaneously injected to rats in the OT group, once every 8 h. 0.4 mL/100 g MDD was administered to rats in the early stage MDD treatment group, and 6 h later changed to NS (once per 12 h).0.4 mL/100 g MDD was administered to rats in the whole course MDD treatment group, once every 12 h. The accumulative survival rate and morphological manifestations of pancreas and small intestine were observed under microscope 48 h after modeling. Pathologic scores of the pancreas and small intestine were conducted at 4, 6, 24, and 48 h after modeling. Contents of serum amylase (AMY), alanine transaminase (ALT), and TNF-α were also detected. The expression of high mobility group box protein 1 (HMGB1) in the small intestine tissue was also detected by Western blot. The positive rate of bacterial translocation in mesenteric lymph nodes (MLNs) was observed within 48 h. Correlations between serum TNF-α or HMGB1 in small intestinal tissue and pathological scores of the pancreas or the small intestine were analyzed.</p><p><b>RESULTS</b>The accumulative survival rate was 100. 0% in the sham-operation group, 79. 2% in the whole course MDD treatment group, 70. 8% in the OT group, 45. 8% in the early stage MDD treatment group, and 37.5% in the model group. At 6 h after modeling, pathological scores decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 24 and 48 h after modeling, pathological scores of the pancreas and the small intestine decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P <0. 05). At 6, 24, and 48 h after modeling, serum contents of AMY and ALT both decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 48 h after modeling serum contents of AMY and ALT both decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). At 6 h after modeling serum TNF-α levels decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 6, 24, and 48 h after modeling the level of HMGB1 in the small intestinal tissue decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). Of them, HMGB1 levels at 24 and 48 h were lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). The number of MLNs bacterial translocation at 48 h after modeling was lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group and the model group (P < 0.05). Serum TNF-α contents within 6 h were positively correlated with pathological scores of pancreas (r = 0.579, P < 0.01). ROC curve showed that serum TNF-α contents could predict the severity of SAP (ROC = 0.990, 95% Cl: 0.971 to 1.000). HMGB1 in the small intestine was positively correlated with pathological scores of the small intestine (r = 0.620, P < 0.01).</p><p><b>CONCLUSIONS</b>Early stage use of MDD could effectively reduce the release of TNF-α, while whole course use of MDD could effectively inhibit the expression of HMGB1. The latter could preferably attenuate injuries of the pancreas and the small intestine, lower MLNs bacterial translocation, and elevate the survival rate.</p>
