ABSTRACT

Apoptosis is particularly important for the body to inhibit or eliminate Mycobacterium tuberculosis ( Mtb) infection. A series of mechanisms to regulate macrophage apoptosis are triggered after macrophages are infected by Mtb. In Mtb-infected macrophages, there are differentially expressed microRNAs (miRNAs), which can directly bind to the binding sites in the 3′-untranslated region (3′ UTR) of apoptotic genes to regulate the expression of apoptotic genes and the apoptosis of macrophages through the mitochondrial or death receptor pathway. This paper reviewed the miRNAs associated with the apoptosis of Mtb-infected macrophages and the major mechanisms.

ABSTRACT

Osteonecrosis is the most common disorder in femoral head and scaphoid. However, avascular necrosis (AVN) in metacarpal head is a rare disease. In the present study, a 14-year-old male patient complained of right-hand pain with a limited range of motion for one month. Physical examination showed that the active flexion was 70° and the extension was limited to 30° of the metacarpophalangeal (MCP) joints. The grip strength decreased to 60% of the contralateral hand. X-rays demonstrated flattening and sclerotic changes in the long finger and ring finger of metacarpal head. CT scanning indicated cystic, osteochondral defects and sclerotic changes in metacarpal head. Imaging examination further confirmed the diagnosis of AVN in the long metacarpal finger and ring finger. After conservative treatments including splint immobilization, non-steroidal anti-inflammatory drugs (NSAIDs) and physiotherapy, the local pain symptoms of the MCP joint gradually disappeared. The range of motion of MCP joint returned to normal with the grip strength score as 105% of the contralateral hand. MRI confirmed excellent remodeling and regeneration in the metacarpal head at two years later. The clinical characteristics, diagnosis and treatments of AVN of metacarpal head were reviewed. Although radiograph examination is commonly used, early-stage osteonecrosis of the metacarpal head should be confirmed by MRI. Given the rarity of this disorder, there is no consensus on the treatments. Metacarpal necrosis is the more common disorder in adolescent patients with a history of trauma. Considering the potential of bone remodeling, juveniles with metacarpal head necrosis could recover by conservative treatments.

ABSTRACT

Objective:To identify the risk factors for premature proximal femur physeal closure (PPC) in children treated surgically for femoral neck fractures.Methods:Data of 106 children with an open triradiate cartilage who were treated surgically for a femoral neck fracture were retrospectively analyzed. Age, gender, laterality, mechanism of injury, the type of fracture, initial displacement, time to reduction, fixation method, whether the implant crossed the physeal plate, reduction method, reduction quality and development of femoral head avascular necrosis (AVN) were collected. PPC of the proximal femur was assessed through postoperative 6-12 months radiographs.Results:A total of 106 patients with an open triradiate cartilage were followed up, with an average duration of 20.4±13.3 months (range, 6-86 months). The overall rate of PPC following paediatric femoral neck fractures treated surgically was 36.8% (39/106). Among the 39 patients with PPC, 25 were males and 14 were females; the average age at the time of injury was 9.7±3.6 years (range, 3-15 years); 23 patients were involved in left hips and 16 were in right; the mechanisms of injury included motor vehicle accident in 5 fractures, falling injury in 21, sports-related injury in 12 and other causes in 1 fracture; two hips were Delbet type I, and 26 hips and 11 hips were Delbet type II and III, separately; type II and III of initial displacement were involved in 26 and 13 patients, separately; the mean duration from injury to surgery was 3.3±2.8 d (range, 1-14 d); 2 hips were treated with Kirschner wires, 35 hips with screw fixation, and the remaining 2 hips underwent screw and plate fixation; 2 hips had the hardware crossing the proximal femoral growth plate, and the remaining 37 hips didn’t; 15 hips were treated by closed reduction and internal fixation, and the other 24 hips underwent open reduction and internal fixation; anatomical reduction was achieved in 14 patients, acceptable reduction in 24 hips and unacceptable reduction in 1 hip; 24 hips developed AVN at the latest follow-up and the remaining 15 hips didn’t. Statistical analysis indicated that age ( t=3.875, P< 0.001), the severity of initial displacement ( Z=-2.118, P=0.034) and the rate of AVN ( χ2=42.280, P< 0.001) in patients with PPC were significantly higher than those in patients without; Logistic regression analysis confirmed age ( OR=1.288, P=0.011) and AVN ( OR=40.336, P< 0.001) as risk factors for PPC. ROC curve analysis indicated 10 years was the cut off age to significantly increase the rate of PPC. The rate of PPC in patients aged over 10 years (63.6%, 21/33) was significantly higher than that (24.7%, 18/73) in those aged less than 10 years ( χ2=14.848, P< 0.001). Conclusion:Age over 10 years and AVN are risk factors for PPC in children with femoral neck fractures treated surgically.

ABSTRACT

Objective:To evaluate the long-term prognosis and recurrence of young liver transplant recipients with hepatocellular carcinoma(HCC).Methods:Based upon the database of liver transplantation center, clinical data were retrospectively reviewed for 39 young recipients(18~40 years)and 158 middle-aged and elderly recipients(over 40 years)from 2013 to 2017. The parameters of overall survival(OS), recurrence-free survival(RFS)and disease-specific survival(DSS)were compared between two groups.Cox's proportional hazard model was utilized for evaluating the prognostic factors.Results:Significant inter-group difference existed in recurrence rate of HCC. Kaplan-Meier analysis revealed no significant difference in OS rate(1/3-year OS, 82.1%, 66.7% and 86.1%, 74.7%, P>0.05)and DSS rate(1/3-year DSS, 94.9%, 82.1% and 99.4%, 91.1%, P=0.053); RFS rate(1/3-year RFS, 51.3%, 41.0% and 73.0%, 62.7%, P=0.008)showed significant differences; Cox multivariate analysis revealed that AFP>400 μg/L was an independent risk factor for OS, DSS and RFS; poorly differentiated tumors and positive micro-vascular invasion(MVI)were independent risk factor for DSS; poorly differentiated tumors and total tumor size >5 cm were independent risk factors for RFS. Conclusions:Although RFS of young adult group is worse than that in middle-aged and elderly group after LT, no significant inter-group difference exists in OS or DSS. And LT is still a quite effective treatment for young HCC patients.

ABSTRACT

OBJECTIVE@#To investigate the effects of blocking the activation of ERK pathway on the expression of matrix metalloproteinase-9 (MMP-9) and the formation of cerebral edema in SD rats after brain injury.@*METHODS@#Ninety SD rats were randomly divided into 3 equal groups, including a sham-operated group, modified Feeney's traumatic brain injury model group, and ERK inhibition group where the ERK inhibitor SCH772984 (500 μg/kg) was injected via the femoral vein 15 min before brain trauma. At 2 h and 2 days after brain trauma, the permeability of blood-brain barrier was assessed by Evans blue method, the water content of the brain tissue was determined, and the phosphorylation level of ERK and the expression level of MMP-9 mRNA and protein were measured by RT-PCR and Western blotting.@*RESULTS@#Compared with the sham-operated group, the rats with brain trauma exhibited significantly increased level of ERK phosphorylation at 2 h and significantly increased expression of MMP-9 mRNA and protein 2 days after the injury ( < 0.01). Treatment with the ERK inhibitor significantly decreased the phosphorylation level of ERK after the injury ( < 0.01), suppressed over-expression of MMP-9 mRNA and protein 2 days after the injury ( < 0.01). The permeability of blood-brain barrier increased significantly 2 h after brain trauma ( < 0.05) and increased further at 2 days ( < 0.01); the water content of the brain did not change significantly at 2 h ( > 0.05) but increased significantly 2 d after the injury ( < 0.01). Treatment with the ERK inhibitor significantly lowered the permeability of blood-brain barrier and brain water content after brain trauma ( < 0.01).@*CONCLUSIONS@#Blocking the activation of ERK pathway significantly reduced the over-expression of MMP-9 and alleviates the damage of blood-brain barrier and traumatic brain edema, suggesting that ERK signaling pathway plays an important role in traumatic brain edema by regulating the expression of MMP-9.

ABSTRACT

OBJECTIVE To identify the mental state of laryngopharyngeal reflux disease (LPRD) patients by analyzing anxiety scale and depression scale. METHODS The LPRD patients who received treatment in Fuzhou General Hospital were studied. The healthy volunteers were recruited as control group. Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to get the individual scores. Mental states of LPRD patients were finally studied through statistical analysis. RESULTS The scores of anxiety and depression in patients with LPRD were significantly higher than those in control group (anxiety score 50.59±7.24 vs 38.76±7.70, depression score 52.90±7.14 vs 40.63±8.17). The incidence of anxiety and depression in patients with LPRD were significantly higher than that in control group (anxiety rate 56.68% vs 9.80%, depression rate 50.98% vs 11.76%). Significant association was detected between ref lux symptom index score and anxiety or depression score in patients with LPRD(r =0.786, r =0.736, P <0.05). Significant association between LPRD and anxiety and depression were concluded. CONCLUSION The results showed that the patients with LPRD are more prone to be anxiety and depression mental state than healthy control group, and the severity of LPRD symptoms is significantly correlated with the anxiety and depression. This suggests that the patient's mental state should also be emphasized as well as antacids treatment.

The patient with postoperative abdominal hemorrhage underwent reoperation for hemostasis, and other patients with complications were cured after ultrasound-guided puncture and drainage or conservative treatment. Duration of postoperative hospital stay of 181 patients with bile duct injury was 12.6 days (range, 6.0-34.0 days). There was no perioperative death occurred. (4) Follow-up: 157 of 181 patients were followed up for 8.2-201.3 months, with a median follow-up time of 92.7 months. Twenty-eight patients had anastomotic stricture recurred, 16 of which were treated with reoperation, 10 were treated with endoscopic stent implantation, and 2 cases were treated with balloon dilatation in interventional department; the stricture was repaired again in all cases. Thirteen patients had recurrent cholangitis, showing no obvious anastomotic stricture on MRCP, and symptoms can be effectively controlled after conservative treatment. (5) Results of the SF-36 scale assessment: 181 patients with bile duct injury completed the SF-36 scales before definitive repair surgery, and 157 completed one year after definitive repair surgery. All the 50 patients without complications completed SF-36 scales one year after LC. The scores of HRQOL in physiological function, role functioning, somatic pain, general health, vitality, social function, emotional function, mental health, the scores of physical component summary, and mental component summary of 181 patients with bile duct injury before surgery were 79±15, 65±12, 40±17, 42±14, 59±20, 27±15, 48±23, 56±22, 60±11, and 56±11, respectively. The above indices one year after definitive repair surgery were 87±10, 78±15, 71±20, 64±20、68±19, 70±25, 67±21, 69±23, 71±13, 68±15, respectively. The above indices of 50 patients without complications one year after LC were 90±13, 81±20, 87±16, 72±20, 73±15, 86±17, 79±22, 77±19, 82±18, 79±18, respectively. The 181 patients with bile duct injury had significant elevation in above indices one year after definitive repair surgery (t=2.051, 2.016, 3.875, 3.014, 2.563, 3.225, 2.964, 2.357, 2.150, 2.203, P<0.05). The 50 patients without complications also had significant elevation in above indices one year after definitive repair surgery (t=2.817, 2.206, 3.641, 3.112, 3.202, 3.310, 3.011, 2.899, 2.150, 2.118, P<0.05). There were significant differences in the general health and mental health one year after definitive repair surgery between 181 patients with bile duct injury and 50 patients without complications (t=2.014, 2.011, P<0.05), and no significant difference in the physiological function, role functioning, somatic pain, vitality, social function, or emotional function between the two groups (t=0.852, 0.915, 0.907, 1.102, 1.284, 1.120, 0.863, 1.109, P>0.05).@*Conclusion@#Definitive repair surgery can significantly improve HRQOL in patients with bile duct injury caused by LC.

ABSTRACT

Objective@#To estimate future excess mortality attributable to cold spells in Guangzhou, China.@*Methods@#We collected the mortality data and metrological data from 2009-2013 of Guangzhou to calculated the association between cold spell days and non-accidental mortality with GLM model. Then we projected future daily average temperatures (2020-2039 (2020s) , 2050-2069 (2050s) , 2080-2099 (2080s) ) with 5 GCMs models and 2 RCPs (RCP4.5 and RCP8.5) to identify cold spell days. The baseline period was the 1980s (1980-1999). Finally, calculated the yearly cold spells related excess death of 1980s, 2020s, 2050s, and 2080s with average daily death count of non-cold spell days, exposure-response relationship, and yearly number of cold spell days.@*Results@#The average of daily non-accidental mortality in Guangzhou from 2009 to 2013 was 96, and the average of daily average was 22.0 ℃. Cold spell days were associated with 3.3% (95%CI: 0.4%-6.2%) increase in non-accidental mortality. In 1980s, yearly cold spells related deaths were 34 (95%CI: 4-64). In 2020s, the number will increase by 0-10; in 2050s, the number will increase by 1-9; and in 2080s, will increase by 1-9 under the RCP4.5 scenario. In 2020s, the number will increase by 0-9; in 2050s, the number will increase by 1-6; and in 2080s, will increase by 0-11 under the RCP8.5 scenario.@*Conclusion@#The cold spells related non-accidental deaths in Guangzhou will increase in future under climate change.

ABSTRACT

OBJECTIVE To assess the prevalence and analyze the influence factors of laryngopharyngeal reflux disease(LPRD) in the Fuzhou region, in order to provide a theoretical basis for the development of prevention and control measures for LPRD. METHODS A questionnaire survey in residents in Fuzhou by a random cluster sampling was carried out. Individual information, reflux symptom index(RSI) of Belafsky and risk factors were included. Patients more than 13 scores of RSI were defined as LPRD. Data were statistically analyzed. RESULTS A total of 4100 residents were investigated, 4063 of them were available. The prevalence of LPRD was 5.00%. Often eating too much, often drinking strong tea, menolipsis, rhinitis, tonsillitis were closely related to LPRD. CONCLUSION The prevalence of LPRD in Fuzhou region were closely related to many factors.

ABSTRACT

Objective To identify the risk factors of the incidence rate of initial poor graft function (IPGF)in recipients after living donor liver transplantation. Methods Clinical data of 309 patients undergoing living donor liver transplantation were retrospectively analyzed. Candidate risk factors:(1 )donor factors included age,gender and body mass index (BMI);(2)recipient factors included age,gender,BMI and preoperative Child-Pugh classification,model for end-stage liver disease (MELD)grading,preoperative renal insufficiency,serum total bilirubin elevation,hyponatremia and hypopotassaemia;(3)graft factors included graft cold ischemia time,graft recipient weight ratio (GRWR);(4)recipient surgery factors included total operation time,blood loss volume,blood transfusion volume,platelet transfusion and anhepatic phase≥1 00 min. Single factor analysis was performed to identify the potential risk factors of IPGF. Logistic regression analysis was conducted to explore independent risk factors. Results and Conclusions Child-Pugh C of preoperative recipient liver function,MELD score≥20,serum total bilirubin elevation(>68. 4μmol/L),hyponatremia(<1 35 mmol/L), hypopotassaemia (<3. 5 mmol/L)and anhepatic phase≥1 00 min were potential risk factors of IPGF (all P<0. 05 ). Child-Pugh C of preoperative recipient liver function was an independent risk factor of the incidence rate of IPGF following living donor liver transplantation (P=0. 01 9).
