ABSTRACT

Objective:To understand the etiology and clinical characteristics of hospitalized severe community-acquired pneumonia(SCAP) in Changchun, and provide scientific basis for its etiology diagnosis and targeted treatment.Methods:The study subjects included 618 children with clinical diagnosis of SCAP who were hospitalized from January 2016 to December 2019.We collected pharyngeal swabs and alveolar lavage fluid from children.Virus isolation, bacterial culture, time-of-flight mass spectrometry, PCR/RT-PCR, colloidal gold method and Optochin test were used to detect the antigen, nucleic acid and protein profiles in the specimen.Results:There were more boys than girls in hospitalized children with SCAP.The peak age of onset was 7 to 12 months.Most cases occurred in winter and spring.The highest detection rate of SCAP virus was 56.15%(347/618); 73.49%(255/347) were positive for one virus, among which the top five were respiratory syncytial virus (27.8%), influenza A virus (23.9%), influenza B virus (16.1%), rhinovirus (12.2%) and metapneumovirus (10.2%). Two viruses were positive for 19.88%(69/347); three viruses were positive for 4.32%(15/347); four viruses were positive for 2.31%(8/347). Atypical microbial infections were 29.77%(184/618), of which Mycoplasma pneumoniae accounted for 95.65%(176/184). Bacterial infections were 17.31%(107/618), mainly Streptococcus pneumoniae(39.25%, 42/107) and Staphylococcus aureus(24.30%, 26/107). The mixed infection of multiple pathogens was 7.61%(47/618), among which the mixed infection rates of Mycoplasma pneumonia with Streptococcus pneumoniae, virus were 40.43% and 34.04%, respectively.High fever, faster breathing, and perioral cyanosis were risk factors for SCAP, with OR and 95% CI of 7.71 and 4.56-13.04, 2.43 and 2.02-2.93, 3.53 and 2.56-4.86, respectively.Viral co-infection occurred in 36.96%(34/92) of complications such as heart failure, toxic encephalopathy, and myocardial damage; Mycoplasma pneumoniae and other pathogens co-infected 35.29% of children with pleural effusion. Conclusion:The pathogens of SCAP in Changchun are mainly viruses notably, respiratory syncytial virus is the dominant pathogen, followed by Mycoplasma pneumoniae.The bacterial pathogen is mainly Streptococcus pneumoniae.High fever, faster breathing, and cyanosis around the mouth are risk factors for severe pneumonia.Multi-pathogen mixed infection is prone to serious complications.

ABSTRACT

After adequate fluid resuscitation in the early stage of septic shock, excessive accumulation of fluid in the body leads to organ dysfunction, which prolongs hospitalization, mechanical ventilation time, and renal replacement therapy time, and is associated with poor prognosis. The fluid de-escalation therapy is an important fluid management strategy performed in the late stage of septic shock. It aims to clear excess fluid by restricting fluid infusion, using diuretics and renal replacement therapy to achieve a negative fluid balance. The fluid de-escalation therapy contributes to improve clinical outcome of septic shock patients and reduce the mortality. This review mainly discusses the current researches and application progress of the fluid de-escalation therapy of abdominal infection-induced septic shock through clarifying its origin, time and endpoint, method of the therapy, the relationship with the control of the source of abdominal infection and its impact on organ function and clinical outcome. Our study intends to provide guidance for the treatment of abdominal infection-induced septic shock in the late stage, and explore the novel research directions.

ABSTRACT

Objective:To investigate the diagnosis and treatment of children with parainfluenza pneumonia complicated with rhabdomyolysis syndrome and acute kidney injury (AKI).Methods:The clinical manifestations, laboratory and imaging examination results and diagnosis and treatment process of a child with parainfluenza pneumonia complicated with rhabdomyolysis syndrome and AKI admitted to the department of intensive medicine of the Second Affiliated Hospital of Fujian Medical University on July 14th, 2014 were retrospectively analyzed to provide experience and methods for the treatment of such patients.Results:The patient, a Chinese 11-year-old boy, admitted to hospital with "sore throat, fever, and double lower limb pain for 2 days". The clinical manifestations were sore throat, fever, pain in both lower extremities, fatigue, and soy sauce urine. Limb muscle tenderness, bilateral lower limb was obvious. Laboratory examination showed that blood creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), aspartate transaminase (AST), lactate dehydrogenase (LDH), α-hydroxybutyrate dehydrogenase (HBDH) and hematuria myoglobin (Mb) were significantly elevated, and blood parainfluenza viruses (1, 2, 3 types) was positive for immunoglobulin M (IgM) antibodies. Chest X-ray shown bronchial pneumonia in the right lower lung. Pneumonia with rhabdomyolysis syndrome was considered. Anti-infection, fluid hydration, alkalized urine, diuresis and other treatment was initially prescribed. However, the condition became worse, combined with secondary epilepsy, AKI, acute heart failure, transferred to the intensive care unit (ICU). The child was put on mechanical ventilation through oral tracheal intubation, continuous hemofiltration, anti-infection and anti-virus treatment. The child's condition gradually recovered, symptoms and signs disappeared, and finally he was discharged with full recovery.Conclusions:Children with parainfluenza pneumonia can induce rhabdomyolysis. If myalgia is progressively worsened and walking is difficult, we should be highly alert to the occurrence of rhabdomyolysis. And when soy sauce urine, hematuria were noticed, and blood CK, Mb increased significantly, rhabdomyolysis syndrome can be diagnosed. Once the diagnosis is established, rehydration, alkaline urine and diuresis should be carried out in a timely manner to increase myoglobin tubular excretion. Antiviral treatment can reduce the dissolution of striated muscles. If blood purification is needed, hemofiltration and/or plasma exchange can be selected.

ABSTRACT

Objective To evaluate the clinical value of 18 F-FDG PET/CT for restaging, guiding therapeutic strategy and predicting prognosis in patients with postoperative colorectal cancer (PCC). Methods Records of 91 patients (51 males, 40 females;average age (54.90±11.47) years) in whom PCC were eval-uated by 18 F-FDG PET/CT imaging from May 2010 to June 2014 were retrospectively reviewed. All patients underwent evaluation at the First Affiliated Hospital of Soochow University. 18 F-FDG PET/CT results were compared with the results from pathological examination, clinical long-term follow-up (≥6 months ) and conventional imaging. Diagnostic efficiency of 18 F-FDG PET/CT in detecting recurrence and metastases of PCC were calculated. The clinical value of 18 F-FDG PET/CT in restaging and guiding therapeutic strategy were analyzed in patients with true positive results. Kaplan-Meier survival analysis was conducted based on the results of PET/CT and the alteration of therapeutic strategy after PET/CT. Results The sensitivity, specific-ity, accuracy, positive predictive value and negative predictive value of 18 F-FDG PET/CT were 96. 36%(53/55), 83.33%(30/36), 91.21%(83/91), 89.83%(53/59) and 93.75%(30/32), respectively. The median survival time and the 5-year survival rate were 10.00 years and 84% in patients with true negative PET/CT results, and were 6. 33 years and 53% in true positive group. Patients with true negative results showed longer OS and PFS than those with true positive results (χ2=7.753, 8. 933, both P<0.01). Among the 53 patients with true positive PET/CT results, tumor restaging was up-regulated in 32 patients and down-regulated in 2 patients. Therapeutic strategies were changed in 33 patients, in whom the PFS was lon- ger than those without treatment alteration (χ2=4.905, P<0.05) . Conclusion 18 F-FDG PET/CT imaging has the high sensitivity and accuracy in detecting recurrence and metastasis of PCC, with the potential for altering clinical restaging and therapeutic strategy timely.

ABSTRACT

Objective To investigate the changes in the expression of keratin genes in renal tissues during renal ischemia-reperfusion (I/R) injury in mice.Methods Six wild type male C57/B6 mice,aged 50 days,weighing 20-30 g,were divided into 2 groups (n=3 each) using a random number table:sham operation group (Sham group) and I/R group.Right renal arteries and veins were clamped for 1 h followed by reperfusion,and the left kidneys were removed to establish the model of renal I/R injury.At 24 h of reperfusion,blood samples were collected from the left ventricle for determination of serum creatinine and urea nitrogen concentrations by colorimetric method.The right kidney specimens were obtained for pathologic examination and for determination of the expression of kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin mRNA (by quantitative real-time polymerase chain reaction [qRT-PCR]) and keratin genes (by Affemetrixc DNA microarray).The differentially expressed genes identified were further confirmed by qRT-PCR.Results Compared with Sham group,the serum creatinine and urea nitrogen concentrations were significantly increased,the expression of kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin mRNA was up-regulated (P<0.05),and the damage to the renal tubules was aggravated in I/R group.The results of microarray analysis showed that only keratin 20 gene (the expresion was up-regulated) was the differentially expressed gene (P<0.05),and the results measured by qRT-PCR were consistent with those measured by Affemetrixc DNA microarray.Conclusion Keratin 20 gene expression in renal tissues is up-regulated during renal I/R injury in mice,and the change may be involved in the endogenous protective mechanism during renal I/R injury.

ABSTRACT

Objective To study the effect of allicin ( All) on potassium current in single atrial myocytes in rats. Methods Isolated rat atrial myocytes were isolated by perfusion and administered by extracellular perfusion method.Whole cell patch clamp technique was used to record transient outward potassium current ( Ito ) in atrial myocyte. Results In presence of 30 μmol·L-1 of All,the peak current of Ito was significantly reduced from (20.5±2.2) pA/pF to (11.3±2.1) pA/pF at+50 mV of test potential (P<0.01,n=12).This effect of All showed voltage- and concentration-dependence with IC50 of (19.0±2.5)μmol·L-1 .The steady-state activation curve of Ito was shifted to more positive potential and recovery time from inactivation was prolonged.In addition, they fail to find any effect of All on the steady-state inactivation and closed-state inactivation of Ito. Conclusion All can inhibit Ito by slowing down the process of activation and recovery from inactivation of channel.

ABSTRACT

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

ABSTRACT

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.

ABSTRACT

PurposeTo investigate the clinical value of inverted X-ray plain film and MRI examination in the diagnosis of congenital anorectal malformation (CARM). Materials and Methods Thirty-eight cases with operatively proved anorectal malformation were reviewed; inverted X-ray plain film and MRI examination were performed in all patients before surgery. The relationship between the rectum blind side and pubococcygeal line (PC line), and the type of anal atresia was determined, to compare the diagnostic accuracy of inverted plain film with MRI for CARM typing. Results Of all the 38 cases, 19 cases were with low imperforate anus, 8 cases with median imperforate anus, and 11 cases with high imperforate anus. The accuracy rate of inverted X-ray plain film and MRI examination for the diagnosis of CARM typing was 92.1% (35/38) and 97.4% (37/38) respectively, and the difference between them was not statistically significant (χ2=1.37, P>0.05). 7 cases of fistula, 5 cases of spinal cord malformations and 1 case of right kidney agenesis can be clearly demonstrated on MRI. Conclusion Both inverted X-ray plain film and MRI can diagnose the typing of CARM accurately, but MRI is also able to diagnose the fistula, visceral, spinal cord lesion and other abnormalities accompanied with CARM, while reducing the dose of X-ray radiation and damage in children, thus has higher clinical application value compared with inverted X-ray plain film.

ABSTRACT

The development, application and revision of the clinical practice guideline (CPG) in traditional Chinese medicine (TCM) are a whole thing. However, the development and revision of TCM CPGs have been influenced due to lack of TCM CPGs reporting and feedback channel. Therefore, during the TCM standardization network establish-ment, we studied the application model of TCM CPGs with spontaneous reporting network, in order to provide the ba-sis for further TCM CPGs development and revision.

ABSTRACT

Objective To compare the distribution of KCNJ11 polymorphisms between elderly Chinese population with and without hypertension. Methods We examined the mutation of KCNJ11 gene by directly sequencing. Data for the present study were obtained from 250 hypertensive subjects (60 to 83 years old) as well as 250 normotensive subjects (60 to 86 years old). Results We found nine different mutations in KCNJ11, including six novel mutations (I131M, L147I, L147V, L147L, Q235H, G245C). None of the novel mutations were found in the normotensive subjects, and all the residues were conserved in other species. These sequence variants in Chinese population indicate the diversity of the human library and the complexity of hypertension. Conclusions The consistent finding of our present study provided a basis for the development of new strategies to diagnosis and treat hypertension in the elderly.

ABSTRACT

Objective To investigate the change of interleukin-5(IL-5)level and mRNA expression in peripheral blood from asthma patients during paracmasis before and after administration of taurine,and explore its clinical significance.Methods A randomized,placebo control,double blind and prospective study was conduced in 84 patients with mild to moderate asthma During paracmasis.The patients were randomly divided into group A(taurine taken orally for one year from beginning of paracmasis)and group B(placebo taken orally for one year from beginning of paracmasis).The symptom score of asthma,lung function paramcter(FEVI),IL-5 level and mRNA expression in peripheral blood were measured and rccorded before and after treatment.The results were compared with those of healthy control group(group C,n=10).Results There were significant differences in the above indices between group A and group B:symptom score of asthma(12.5 + 4.8 vs 15.2±5.1);lung function parameter[FEV1(L)2.6±0.5 vs 2.2±0.8];IL-5 level(pg/mL)(16.3±4.5 vs 26.9 ±12.7);IL-5 mRNA(0.21 ± 0.09 vs 0.35 ± 0.14).The basic level and mRNA expression of IL-5 were significantly higher in group A and group B than that in group C.The serum level and mRNA expression of IL-5 were positively correlative with symptom score of asthma in group A(r=0.42,P<0.05).Conclusion The exists ovcrexpression of IL-5 in asthma patients during paracmasis and IL-5 level reflects the scverity of pathogenetic condition.Therefore,IL-5 measurement may provide a good reference for clinical therapy of asthma.
