ABSTRACT

Drug-induced hyperglycemia/diabetes is a global issue. Some drugs induce hyperglycemia by activating the pregnane X receptor (PXR), but the mechanism is unclear. Here, we report that PXR activation induces hyperglycemia by impairing hepatic glucose metabolism due to inhibition of the hepatocyte nuclear factor 4-alpha (HNF4α)‒glucose transporter 2 (GLUT2) pathway. The PXR agonists atorvastatin and rifampicin significantly downregulated GLUT2 and HNF4α expression, and impaired glucose uptake and utilization in HepG2 cells. Overexpression of PXR downregulated GLUT2 and HNF4α expression, while silencing PXR upregulated HNF4α and GLUT2 expression. Silencing HNF4α decreased GLUT2 expression, while overexpressing HNF4α increased GLUT2 expression and glucose uptake. Silencing PXR or overexpressing HNF4α reversed the atorvastatin-induced decrease in GLUT2 expression and glucose uptake. In human primary hepatocytes, atorvastatin downregulated GLUT2 and HNF4α mRNA expression, which could be attenuated by silencing PXR. Silencing HNF4α downregulated GLUT2 mRNA expression. These findings were reproduced with mouse primary hepatocytes. Hnf4α plasmid increased Slc2a2 promoter activity. Hnf4α silencing or pregnenolone-16α-carbonitrile (PCN) suppressed the Slc2a2 promoter activity by decreasing HNF4α recruitment to the Slc2a2 promoter. Liver-specific Hnf4α deletion and PCN impaired glucose tolerance and hepatic glucose uptake, and decreased the expression of hepatic HNF4α and GLUT2. In conclusion, PXR activation impaired hepatic glucose metabolism partly by inhibiting the HNF4α‒GLUT2 pathway. These results highlight the molecular mechanisms by which PXR activators induce hyperglycemia/diabetes.

ABSTRACT

OBJECTIVE@#To explore feasibility of closed reduction technique under monitoring of C-arm and three screws in the fixation of abduction and insertion femoral neck fracture.@*METHODS@#Seventeen patients with abduction and insertion femoral neck fracture operated from January 2014 to December 2019 were analyzed retrospectively, including 10 males and 7 females, aged from 21 to 59(42.09±7.30) years old. According to preoperative X-ray and CT data, angle of retroversion and abduction displacement of femoral head were determined. Two 2 mm diameter Kirschner wires crossed and gently knocked into the bone of the acetabular roof from outside and front of femoral head. The proximal fracture segment was fixed on the acetabulum. Under the monitoring of C-arm, lower limb (distal fracture segment) was gradually rotated inward and retracted against direction of fracture displacement, three cannulated screws were used for internal fixation after anatomical reduction of the distal fracture end and the proximal fracture end. Garden index was evaluated, postoperative complications were observed, and Harris functional score was performed.@*RESULTS@#All 17 cases of femoral neck fracture with abduction and insertion were successfully completed closed reduction and internal fixation. The operation time was 36 to 68(43.87±7.63) min and intraoperative bleeding was 15 to 50(28.36±5.93) ml. The quality of fracture reduction was evaluated by garden index during operation. There were 12 cases of anatomical reduction, 5 cases of acceptable reduction, and no cases of unsuccessful reduction were changed to open reduction. 17 cases were followed up for 3 to 41(27.5±8.4) months. There were no complications such as femoral head necrosis, fracture nonunion, hip impingement and femoral neck shortening. MR examination showed no femoral head necrosis and articular cartilage injury. Two years after operation, Harris score of hip joint was excellent in 13 cases and good in 4 cases.@*CONCLUSION@#Closed reduction and three screws internal fixation can obtain good anatomical reduction rate and therapeutic effect in the treatment of abduction and insertion femoral neck fracture.

ABSTRACT

OBJECTIVE@#To compare clinical effects of different postoperative rehabilitation modes on lumbar degenerative diseases, and explore influence of rehabilitation mode and other factors on postoperative effect.@*METHODS@#From June 2013 to July 2016, totally 900 patients were admitted from nine tertiary hospitals in Beijing to perform single segment bone grafting and internal fixation due to lumbar degenerative diseases were prospectively analyzed. There were 428 males and 472 females, the age of patient over 18 years old, with an average of (51.42±12.41) years old;according to patients' subjective wishes and actual residence conditions, all patients were divided into three groups, named as observation group 1 (performed integrated rehabilitation approach and orthopedic treatment model intervention), observation group 2 (performed integrated rehabilitation approach and orthopedic treatment, classified rehabilitation model intervention), and control group(performed routine rehabilitation model intervention). Visual analogue scale(VAS), Oswestry Disability Index(ODI) and Japanese Orthopaedic Association (JOA) were used to evaluate postoperative efficacy among three groups at 24 weeks. Possible factors affecting the postoperative efficacy including age, age grouping, gender, body mass index (BMI), BMI grouping, education level, visiting hospital, payment method of medical expenses, preoperative complications, preoperative JOA score, clinical diagnosis, surgery section, operative method, intraoperative bleeding volume, postoperative complications and rehabilitation mode were listed as independent variables, and postoperative ODI score at 24 weeks as dependent variables. Univariate analysis was used to analyze relationship between influencing factors and postoperative efficacy. Multiple linear regression was used to analyze relationship between influencing factors, rehabilitation mode and postoperative ODI score at 24 weeks, in further to find out the main reasons which affect postoperative efficacy, and to analyze impact of rehabilitation mode on postoperative efficacy.@*RESULTS@#All patients were followed up for 24 weeks after operation. All incisions healed at stage I with stable internal fixation. (1)Evaluation of postoperative efficacy:① There were no statistical differences in preoperative VAS and ODI among three groups(@*CONCLUSION@#Preoperative JOA score, gender, age could predict postoperative clinical effects of lumbar degenerative diseases in varying degrees treated with single level bone graft fusion and internal fixation. Different rehabilitation modes could improve clinical effects. Intergrated rehabilitation orthopedic treatment model and integrated rehabilitation approach and orthopedic treatment with classifiedrehabilitation model are superior to conventional rehabilitation model in improving patients' postoperative function and relieving pain, which is worthy of promoting in clinical.

ABSTRACT

To investigate the feasibility and safety of endoscopic trans-gastric cholecystolithotomy(ETGC) combined with endoscopic retrograde cholangiopancreatography (ERCP) for cholecystolithiasis and choledocholithiasis. Data of patients with cholecystolithiasis and choledocholithiasis who underwent ETGC after ERCP in Zhongshan Hospital Affiliated to Fudan University from November 2018 to April 2019 were analyzed. Six patients with cholecystolithiasis and choledocholithiasis, 4 males and 2 females, were included in this study.The interval between ERCP and ETGC ranged from 1 to 77 days (median 5 days). All the 6 patients successfully completed ETGC after ERCP, with a surgical success rate of 100%. All the patients had multiple cholecystolithiasis and one patient was complicated with gallbladder polyps.The ETGC operation time was 22-100 min (median 65 min), and the length of hospital stay was 3-9 d (median 6.5 d). Two patients had dull pain in the upper abdomen and increased body temperature after surgery. Abdominal ultrasound in one patient suggested local effusion in the right upper abdomen.Both patients improved after conservative treatment.None of the patients had cholecystitis and cholangitis related symptoms such as right upper abdominal pain or fever during postoperative follow-up, and the follow-up rate was 100%with median follow-up time of 18 month.All the 6 patients underwent abdominal ultrasound examination after surgery. No recurrence occurred in 5 patients. One of the patients showed cholesterol crystals in the gallbladder wall and bile mud deposition.ETGC combined with ERCP is safe and feasible for cholecystolithiasis and choledocholithiasis.

ABSTRACT

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guideline 2019 recommended that lymph node dissection for advanced rectal cancer should include the lymphatic adipose tissue at the root of the inferior mesenteric vessels, but the ligation site of the inferior mesenteric artery (IMA) was not determined, and the NCCN guideline did not indicate clearly whether to retain the left colonic artery (LCA). Controversy over whether to retain LCA is no more than whether it can reduce the incidence of anastomotic complications or postoperative functional damage without affecting the patients' oncological outcome. Focusing on the above problems, this paper reviews the latest research progress. In conclusion, it is believed that the advantages of retaining LCA are supported by most studies, which can improve the blood supply of the proximal anastomosis, and technically can achieve the same range of lymph node dissection as IMA high ligation. However, whether it affects the survival of patients, reduces the incidence of anastomotic leakage, and improves the quality of life of patients, more high-quality evidence-based medical evidence is still needed.

ABSTRACT

Objective: To explore the efficacy of relocation and expansion pharyngoplasty by suspension sutures in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Seventy-three patients(including 60 males and 13 females) with OSAHS admitted to the department of otorhinolaryngology of our hospital in recent two years were retrospectively analyzed. All the patients had velopharyngeal obstructionevaluated by electronic endoscopic Müller test and were divided into control group (34 cases) and observation group (39 cases). The patients in the control group were performed modified uvulopalatopharyngoplasty, while those in the observation group were performed relocation and expansion pharyngoplasty by suspension sutures.The scores of ESS, AHI and LSaO2 before and after treatment were collected and compared. Results: The total effective rate of the observation group was 94.87%, which was significantly higher than 79.41% of the control group. The AHI was lower and LSaO2 value was higher (χ2=-1. 896,-1. 968,P<0.05)in the observation group. The sleeping symptoms and quality of life of the two groups were significantly improved. The ESS score of the observation group was decreased more significantly than that of the control group after treatment, and the difference was statistically significant (χ2=-1.451,P<0.05). The incidence of foreign body sensation in pharynx of the observation group (89.74%) was higher than that of the control group (55.88%), and the postoperative bleeding and postoperative recurrence rate (0.00%, 2.56%) was lower than that of the control group (8.82%, 14.70%)with statistical significance (χ2=4.738,4.249,4.119,P<0.05).The incidence of transient nasopharyngeal reflux in both groups was low and statistically insignificant (χ2=0.629,P>0.05). Conclusions: Preoperative strict screening of indications plays an important role in the selection of palatopharyngeal surgery methods and curative effect. Relocation and expansion pharyngoplasty by suspension sutures can improve the clinical efficacy of OSAHS with better safety and less recurrence.

ABSTRACT

Ultrasonic bubble detection has been widely used in predicting the risk of decompression sickness and evaluating the efficiency and safety of decompression procedures. Currently, the widely used SPENCER scale is conducted by using Doppler ultrasound to monitor the bubble signal in the precordial region of subjects. KM grading system is a computerized system based on Doppler ultrasound. The grading score can be converted into SPENCER bubble grading scale score and the bubble grading is precise and suitable for the motion status. On the basis of the above two methods, the KISMAN integrated severity score, extended SPENCER bubble grading and simplified Doppler bubble grading system were established. They not only coordinated analysis of Doppler ultrasound bubble detection results with other risk factors of decompression disease, but also convenient to use computer for processing detection results. With the in-depth application of Fourier technique and empirical mode decomposition in Doppler audio bubble signal detection, methods such as three-parameter fuzzy analysis and energy operator method are playing an important role in automatic bubble analysis. Optimization of detection technology and improvement of sensitivity and accuracy of automatic analysis are important development directions in the field of decompression bubble Doppler grating technology.

ABSTRACT

Objective:To perform a prospective cohort study to identify individual susceptibility of glucocorticoid (GC) -associated osteonecrosis of the femoral head (GA-ONFH) and their clinical and genetic risk factors. Methods:The present prospective cohort study enrolled patients who received their first GC therapy between July 2015 and January 2018 at Zhongshan Hospital. All patients did not receive any GC treatment before enrollment. Further, they planned to start GC treatment with the dose (equivalent prednisone) of ≥30 mg/d, lasted ≥3 weeks, or pulse dose ≥200 mg/d, lasted ≥3 d. Blood samples were collected before GC treatment to evaluate bone metabolism and its released factors. Hip MRI was performed at the 1st, 3rd, 6th, 12th and 24th month to diagnose GA-ONFH. All patients were followed-up for ≥2 years. The endpoint was regarded as diagnosis of GA-ONFH or completion of 2 years follow-up. Lasso regression was performed to determine which clinical features were associated with GA-ONFH. A nested case-control sub-cohort (A, n=12) was established prospectively based on the main cohort by 1∶1 matching. Whole exome sequencing was performed to screen differential and functional candidate single nucleotide polymorphisms and insertion-deletions (SNP/InDels). Another sub-cohort (B, n=50) was constructed retrospectively in patients with GA-ONFH and non-ONFH patients received standard high dose GC treatment for more than two years. The candidate SNP/InDels were verified by Sanger sequencing based on the patients from sub-cohort B. Results:A total of 96 patients were enrolled of which 88 of them (32 males and 56 females, mean age 42.30 years) completed follow-up. Eight cases (9.1%) were diagnosed with GA-ONFH. The median time from the start of GC therapy to the diagnosis of ONFH was 53.00(34.00,13.50) days. The baseline characteristics, such as age, sex and body mass index, indicated no significant difference between the ONFH group and the non-ONFH group. The cumulative GC dose of the ONFH patients in the first month was higher than that of non-ONFH [32.74(29.55, 47.05) mg/kg vs. 24.00(21.10, 29.45) mg/kg, Z=-2.410, P=0.016]. However, there was no significant difference of patients who underwent pulse therapy (37.5% vs. 10.0%, adjusted χ 2=2.829, P=0.093). The ratio of serum apolipoprotein B/apolipoprotein A1 (ApoB/ApoA1) in patients with ONFH was higher than that in non-ONFH group before GC use [0.95(0.80, 1.50) vs. 0.70(0.60, 0.80), Z=-2.875, P=0.000]. Due to the multicollinearity, Lasso regression model was performed to reduce overfitting. All variables were included in the model. The results suggested that higher ApoB/ApoA1 ratio, lower serum β-c-terminal telopeptide (β-CTX) and higher cumulative GC dose in the first month were the top three risk factors of GA-ONFH. This model had an accuracy of 0.982 in internal validation. Seven differential candidate SNP/InDels were found by whole exome sequencing of sub-cohort A. We further verified these SNP/InDels in sub-cohort B. The patients with COLEC12 mutation (rs2305027, G1816A) were at risk of GA-ONFH ( OR=6.00, 95% CI: 1.17, 30.73). Conclusion:Higher first-month GC dose, lower serum β-CTX level before treatment, higher ApoB/ApoA1 ratio and COLEC12 mutation (rs2305027, G1816A) could increase the risk of GA-ONFH.

ABSTRACT

Systematic integration teaching is a curriculum system focusing on organs and systems, which is an important direction of medical education reform in China. Based on the practice of integrated curriculum teaching in Dalian Medical University for more than 10 years, combined with the experience in 15 medical colleges and universities in China, this paper analyzed the modes of systematic integrated teaching at the basic medicine teaching stage for medical higher education, and specified the purpose and significance of this teaching reform. The results showed that: (1) The systematic integrated teaching is a well-accepted and widely used teaching mode in domestic medical colleges and universities, which mainly includes three types of methodologies, i.e., integration of basic medicine courses, integration of clinical medicine courses and integration of basic and clinical medicine courses. The systematic integrated teaching is carried out by reforming various teaching methods including problem-based learning (PBL), case-based learning (CBL) and team-based learning (TBL). (2) The systematic integration teaching at the basic medicine teaching stage can significantly optimize the transition between basic and clinical courses, promote the cooperation and exchange between basic and clinical teachers, and improve the medical students' knowledge construction and critical thinking, and teachers' teaching ability as well. (3) The systematic integration teaching concept of "Six focuses" and "Five combinations" effectively guides the design and implementation of the integrated curriculum at the basic medical teaching stage of Dalian Medical University. With the deepening and development of medical education system reform in China, giving full play to the respective advantages of the systematic integrated teaching and traditional single-subject teaching at the basic medicine stage, and strengthening the integration of basic and clinical courses will play an important role in optimizing medical education curriculum system with Chinese characteristics.

Objective:To observe the controlling effect of addition and subtraction therapy of Xuanbi tang on knee osteoarthritis of rheumatic fever arthralgia type (KOA) at attack stage and to investigate the influence to acute inflammation factors. Method:One hundred and twenty-eight patients were randomly divided into control group and observation group (1∶1) by random number table with SAS software. The patients in both groups got celecoxib capsules, 0.2 g/time, 1 time/day, glucosamine hydrochloride capsule, 1 grain/time, 2 times/day. Patients in control group addiiontally got Simiaowan, 6 g/time, 2 times/day. Patients in observation group got addition and subtraction therapy of Xuanbitang, 1 dose/day, with a treatment course of 2 weeks in both groups. Visual analogue scale of pain (VAS) was used to discuss pain degree of knee joint, and the VAS scores during activity and resting state were recorded every day, and the time to pain relief and time to pain disappearance were also recorded. Before and after treatment, the scores of osteoarthritis index visual scale of Western Ontario and McMaster University (WOMAC), scores of swelling degree and scores of rheumatism heat arthralgia syndrome were graded. The levels of high sensitive C-reactive protein (hs CRP), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and serum matrix metalloproteinase-3 (MMP-3) were detected before and after treatment. In addition, safety was evaluated and discussed. Result:The comprehensive total effective rate in observation group was 95.00% (57/60), higher than 83.05% (49/59) in control group (P<0.05). At the third, seventh, tenth, fourteenth day after treatment, scores of knee joint pain degree in observation group were lower than those in control group (P<0.01). Time to pain relief and time to pain disappearance were shorter than those in control group (P<0.01). Scores of WOMAC, swelling degree and rheumatism heat arthralgia syndrome were all lower than those in control group (P<0.01). Levels of hs-CRP, IL-1β, IL-6, TNF-α and MMP-3 were lower than those in control group (P<0.01). In addition, there was no adverse reaction related to Xuanbitang. Conclusion:Addition and subtraction therapy of Xuanbitang can relieve pain, swelling and other symptoms, improve knee joint function, shorten the course of disease, and control the acute inflammatory reaction, with significant clinical efficacy and safety.

ABSTRACT

To prospectively evaluate the correlation between intravoxel incoherent motion (IVIM)-derived parameters and CT perfusion parameters as well as the pathological grade in insulinoma. A total of 55 patients with suspected insulinoma undergoing IVIM and CT perfusion scans were prospectively enrolled. The images were post-processed to obtain IVIM parameters including apparent diffusion coefficient (ADC),diffusion (D),perfusion correlated diffusion (D*),and f,and CT perfusion parameters including blood flow (BF),blood volume (BV),and permeability (PM). The pathological specimens were stained to obtain pathological parameters including the grading,ki-67 index,and the mitotic count. The IVIM derived parameters of normal pancreas including head,body,and tail as well as that of the pancreatic insulinoma were compared. The correlation between IVIM parameters and CT perfusion parameters as well as the pathological parameters was analyzed. ADC and D values of pancreatic tail were significantly lower than those of the pancreatic head and neck (all 0.05). IVIM parameters differ at different anatomical parts of normal pancreas. IVIM parameters can distinguish normal pancreatic parenchyma from insulinoma. The ADC value is weakly correlated with BF.

The cell survival rate and apoptosis rate were calculated. Transwell assay was used to test the migration of cells after treated with different doses of metformin (10,20 mmol/L)for 24 h. The number of migrating cells was recorded. qRT-PCR and Western blotting assay were performed to determine mRNA and protein expression of E-cadherin ,Vimentin and RGC- 32 in cells. RESULTS :Compared with control group and 5 mmol/L metformin group ,survival rate of cells were decreased significantly in 10,20 mmol/L metformin groups ,while apoptosis rate was increased significantly ;the apoptosis rate in 20 mmol/L metformin group was significantly higher than 10 mmol/L metformin group (P<0.05). Compared with control group , the number of migrating cells was decreased significantly in 10,20 mmol/L metformin groups ,and the 20 mmol/L metformin group was significantly lower than 10 mmol/L metformin group (P<0.05). Relative mRNA and protein expression of E-cadherin were increased significantly in 10,20 mmol/L metformin groups ,and relative mRNA expression of E-cadherin in 20 mmol/L metformin group was significantly higher than 10 mmol/L metformin group. Relative mRNA expression of Vimentin in 10 mmol/L metformin group ,relative mRNA and protein expression of Vimentin in 20 mmol/L metformin group ,relative mRNA and protein expression of RGC- 32 in 10,20 mmol/L metformin groups were decreased significantly ;relative mRNA and protein expression of Vimentin as well as mRNA expression of RGC- 32 in 20 mmol/L metformin group were significantly lower than 10 mmol/L metformin group (P<0.05 or P<0.01). CONCLUSIONS :Metformin can inhibit the proliferation and migration of pancreatic cancer cells through smael-independent pathways in a dose- dependent manner ,and promote their apoptosis ,which is associated with the inhibition epithelial- mesenchymal transition and the expression of RGC- 32 of pancreatic cancer.

ABSTRACT

Objective:To explore the clinical characteristics of children with Streptococcus pneumoniae cellulitis. Methods:The bacterial culture information management system in 18 children′s hospitals from January 2012 to December 2017 were reviewed.Among 1 138 children diagnosed with invasive pneumococcal disease(IPD), 7 cases were hospitalized with cellulitis.Clinical information was collected and analyzed.Results:Seven cases of Streptococcus pneumoniae cellulitis accounted for 0.6%(7/1 138 cases) of 1 138 IPD cases in 18 hospitals.There were 5 males and 2 females.The onset age was from 1 month to 6 years old, and the median age was 2 years old.There were 4 cases in rural areas and 3 cases in urban areas.Langerhans cell histiocytosis (LCH) was found in 1 case.Clinical manifestations: fever, local swelling and pain with infection.The focus of cellulitis: orbital cellulitis in 2 cases, buccal infection in 2 cases, upper extremity, head and buttock infection in 1 case, respectively.At the beginning of the disease: 2 cases of orbital cellulitis were accompanied by nasosinusitis and suppurative otitis media, 1 case was treated with acute periapical inflammation, 1 case was 10 months after chemotherapy.Type of infection: 6 cases were complicated with bloodstream infection, 2 cases with bacterial meningitis and 1 case with pneumonia.Other culture results: 6 cases of Streptococcus pneumoniae were cultured in peripheral blood, 2 cases were positive in local pus culture.Drug sensitivity test: 6 cases were sensitive to Penicillin and Cephalosporin (Cefotaxime/Ceftriaxone), 1 case was resistant.Treatment: 3 patients were treated with Cephalosporins alone, 2 cases with Cephalosporins and Penicillins, 2 cases with Vancomycin and Meropenem for meningitis, 3 cases with local abscess by incision and drainage, 2 cases with meningitis in Intensive Care Unit, and 1 case with endotracheal intubation and ventilator assisted ventilation.The average length of stay was 14.3 days(5-41 days). Discharge outcome: 6 cases improved and 1 case died. Conclusions:Cellulitis is a rare type of infection in children with IPD.It is mainly found in the head, face and around the orbit.It may be accompanied by bloodstream infection or bacterial meningitis.Most of them have a good prognosis.

ABSTRACT

Objective:To explore the clinical characteristics, drug resistance and the serotype distribution of the isolates from peadiatric patients with pneumococcal meningitis (PM).Methods:Clinical data, follow-up outcomes, drug susceptibility of isolated strains and serotyping results of 72 children diagnosed as PM and hospitalized in Beijing Children′s Hospital, Capital Medical University, from January 2012 to December 2017 were retrospectively analyzed, and the independent risk factors of mortality in the PM patients were analyzed.Results:There were 46 males and 26 females.In 72 PM cases, with the age ranging from 1 month to 9 years, and hospital stay from 1 to 363 days(median, 22.0 d). A total of 71 cases (98.6%) had community-acquired infections.There were 28 cases (38.9%) with definite underlying diseases, the top 3 of which were cerebrospinal fluid rhinorrhea(6 cases), head trauma (4 cases)and immunodeficiency diseases (4 cases). Fever (72 cases, 100.0%) was the most common clinical symptom, followed by depression of spirit, change of consciousness (46 cases, 63.9%), vomitting (45 cases, 62.5%), convulsion (42 cases, 58.3%), increased tension of anterior fontanelle (27 cases, 37.5%) and headache (17 cases, 23.6%) .There were 44 cases (61.1%) of neurological complications, including 29 cases (40.3%) of subdural effusion.Bacterial meningitis recurred in 2 cases, both of which were recurrent Streptococcus pneumoniae infection.The intracranial infections were divided into meningitis (43.1%, 31/72 cases) and meningoencephalitis (56.9%, 41/72 cases) .The penicillin nonsensitive rate of meningitis isolates was 74.3%, and their resistance rate to Erythromycin, Clindamycin and Tetracycline were 95.7%, 95.7% and 89.1%, respectively.All meningitis isolates were susceptible to Levofloxacin, Vancomycin and Linezolid.The serotypes of 24 cases (33.3%) were identified, among which 8 strains were type 19F (33.4%), 5 strains were type 14, 4 strains were type 23F, 3 strains were type 6A, 2 strains were type 19A, 1 strain was type 1 and 1 strain was type 15B, with a 13-valent protein-polysaccharide conjugate vaccine (PCV13) coverage rate of 95.8%(23/24 strains). Among all children that were followed up, 51 cases got better, 21 cases (case fatality rate was 29.2%) were confirmed dead, and 21 children (29.2%) had sequelae.The multiva-riate Logistic regression analysis suggested that respiratory failure and peripheral blood white blood cell count <4×10 9/L were independent risk factors for death of children with PM(all P<0.05). Conclusions:Most PM cases in this center are children under 5 years old.Cerebrospinal fluid rhinorrhea, head trauma and immunodeficiency diseases are common underlying diseases in children with PM.Respiratory failure or peripheral blood leukopenia during the course of the disease may indicate a poor prognosis.
