Objective To explore the correlation between cytomegalovirus pneumonia (CMV-IP) and viral load in renal transplant recipients and to find out the threshold value of viral load for predicting CMV-IP. Methods The blood samples of 56 renal transplant recipients were taken weekly for the first 2 months and every 2 weeks for 2-6 months after transplantation.Real-time PCR were used to quantify the plasma CMV DNA.The mean viral loads of CMV-IP group and non-CMV-IP group in each time were compared using Wilcoxon test.Different cut-off values were tested to find the suitable values to predict the CMV-IP. Results Of the 56 recipients,8 (14.3%) developed CMV-IP.The viral loads were near zero in the first 4 weeks in both groups;from week 5 the viral load of CMV-IP group increased gradually and reached the climax at week 8 and then declined,but the load of non-CMV-IP group fluctuated at a low level.During weeks 5-11,the viral loads of CMV-IP group were higher than those of non-VMV-IP group.At 5,7 and 9 weeks,the differences of the viral loads between the 2 groups were significant (P

Objective To explore the diagnosis,treatment and prognosis of primary gastric malignant (lymphoma)(PGML).Methods The diagnosis and treatment data of 21 cases of PGML admitted in our(hospital) during 8 years was retrospectively analyzed.The diagnostic methods included barium meal(examination),gastroscopy,B type ultrasonography,and CT scan.All patients underwent operative treatment and most of the patients received adjuvant chemotherapy.Results Upper abdominal pain,digestive tract bleeding,emaciation and abdominal mass were common clinical manifestations of PGML.The resectabilty rate of PGML was 90.5% while the 5-year survival rate was 57.1%.Conclusions The key to a satisfactory prognosis was early diagnosis,radical curative operation and combined treatment.

Objective The aim of this randomized,double-blind,placebo-controlled trial was to evaluate the efficacy of the Saccharomyces boulardii (S.boulardii) power in preventing antibiotic-associated diarrhea (AAD) in hospitalized children with pneumonia.Methods Two hundred and forty-five hospitalized children with pneumonia were randomly divided into two groups,group 1 treated with antibiotics and S.boulardii power (n =104),and group 2 with antibiotics and placebo,along with S.boulardii power and zinc when suffered from diarrhea (n =141).All children received montmorillonite powder and fluid replacement therapy for diarrhea.The stool frequency and consistency were observed.Diarrhea incidence,diarrhea and pneumonia duration of treatment,and therapeutic effect were recorded.Results AAD is more prevalent in group 2 than in group 1 (P ＜0.05).A 55.7％ relative risk reduction in AAD was seen in group 1 compared with group 2 (RR =0.443,95％CI 0.233 ～ 0.845,P =0.012).Patients with preventive treatment of S.boulardii power in broup 1 had lower AAD incidence compared with those in group 2 (P ＜ 0.05).Both the diarrhea and pneumonia duration of treatment in group 1 were shorter than that in group 2(P =0.001 for diarrhea duration,P =0.030 for pneumonia duration,respectively).No drug related adverse reactions were found during the observation period.Conclusion Preventive use of S.boulardii power may effectively reduce the risk of AAD,improve therapeutic effect,and shorten hospital stays for hospitalized children with pneumonia.

Objective To evaluate the apphcation value of peripheral blood neutrophil CD64 expression in early differential diagnosis of etiology in children with community-acquired pneumonia.Methods From June 2014 to June 2015 in our hospital,total of 99 cases of different pathogen infection were divided into three groups,bacterial pneumonia group (n =41),non-bacterial pneumonia group(n =38),healthy children group (n =20);and the non-bacterial pneumonia group was divided into two subgroups,viral pneumonia group (n =22) and mycoplasma pneumoniae pneumonia group(n =16).Flow cytometry was used to test the median fluorescence intensity (MFI) of peripheral blood neutrophil CD64.The levels of peripheral blood CRP,WBC and neutrophil percentage were detected.Results The levels of CD64 expression,CRP and WBC in bacterial pneumonia group were statistically higher than those of non-bacterial pneumonia group and healthy children group respectively (both P ＜ 0.01).The optimal cutoff value of CD64 was 6 519 MFI when using ROC curve,and the sensitivity and specificity of the diagnosis of bacterial pneumonia were 87.8％ and 89.7％ respectively.The levels of CD64 expression in bacterial pneumonia group were significantly higher than those in viral pneumonia group,mycoplasma pneumoniae pneumonia group and healthy children group (all P ＜ 0.01).Conclusion The expression of peripheral blood neutrophil CD64 increases in children with community-acquired pneumonia of bacteria infection.It can be used to guide early diagnosis of children with bacterial pneumonia and the using of antibiotics.

This article briefly summarized the meaning, category and function of qi, tubes and viscera in human body respectively after combining exploring the theories of traditional Chinese medicine(TCM) and clinical practices. Afterward, we put forward the theory of Qi-Tube-Viscera and elaborated its close relationship with the physiological status of the human, and then we thought the relationships of qi, tube and viscera respectively, at last we draw a conclusion that qi, tube and viscera only came from qi. And the clinical guiding significance of the theory of Qi-Tube-Viscera and itsBalanced steady state, Nature and Man in One, State medicine were narrated to demonstrate that new theory of Qi-Tube-Viscera has high signifance in the theory of TCM and clinical practice.

BACKGROUND:Extensive studies have shown that transcutaneous electrical nerve stimulation (TENS) plays a positive role in relieving the pain caused by a variety of diseases. However, its exact effect to manage pain in patients with knee osteoarthritis is stil controversial. TENS is classified into h-TENS and l-TENS, but currently its respective role in relieving the pain caused by knee osteoarthritis is not clear yet. OBJECTIVE: To compare the efficacy of h-TENS and l-TENS on pain relieving among patients with knee osteoarthritis. METHODS: A computer-based search was performed on PubMed, Embase and Cochrane database for randomized controled trials on TENS for the treatment of knee pain in patients with knee osteoarthritis which were reported before February 2014. Methodology quality of the trials was criticaly assessed and relative data were extracted. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software. RESULTS AND CONCLUSION:A total of 10 randomized controled trials involving 519 cases were included. The results of meta-analysis showed that the h-TENS group had significant effects on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.56, 95%CI(-0.98,-0.15),P=0.008]; the l-TENS group had no significant effect on pain relief in knee osteoarthritis patients in comparison to the control group [MD=-0.13, 95%CI(-1.63, 1.38),P=0.87]; the h-TENS group had significant effect on pain relief in knee osteoarthritis patients in comparison to the l-TENS group [MD=-0.85, 95%CI(-1.32, -0.37), P=0.000 5]. These findings indicate that h-TENS performs something positive to reduce pain in knee osteoarthritis patients that l-TENS cannot do. Owing to the limitations of this study, further work is needed to determine the role of TENS in pain management among patients with knee osteoarthritis.

BACKGROUND:Ultrasonic therapy is one of several physical therapy modalities suggested for the management of pain and loss of function due to osteoarthritis. However, its effectiveness stil remains controversial in the previous studies.
OBJECTIVE:To analyze the effect of ultrasonic therapy for the treatment of relieving knee osteoarthritis pain.
METHODS:A retrieval of Pubmed, Ovid/Medline, Ovid/EMBASE, and Cochranee database was performed. The relevant literatures were manual y retrieved. The retrieval deadline was set on March 31, 2014. Randomized control ed trials on ultrasonic therapy of knee osteoarthritis were col ected.
RESULTS AND CONCLUSION:A total of eight studies of meta-analysis were accumulated. Among them, six studies adopted visual analog scale and Western Ontario and McMaster Universities Arthritis Index, one study adopted visual analog scale only, and one study adopted Western Ontario and McMaster Universities Arthritis Index. Then the Western Ontario and McMaster Universities Arthritis Index scores were transformed into visual analog scale scores for data analysis. There was a statistical difference between the groups in the visual analog scale pain score (standardized standard deviation:-0.51;95%confidence interval:-0.68,-0.33;P=0.05). Ultrasonic therapy is an effective method for knee osteoarthritis pain.

Basic knowledge of forensic science is theoretical and abstract,therefore,confir-matory experiment teaching is often adopted in the experiment teaching. International education has become an important topic in medical colleges and universities. Forensic medicine is a compulsory subject for medical international students. This article discussed the exploration and practice in teach-ing forensic medicine for international students at Wenzhou Medical University,which included faculty constructing and training,encouraging whole English teaching by young teachers,applying heuristic interactive teaching and case teaching,establishing strict attendance and appraisal system and con-ducting comprehensive evaluation on medical teaching quality and teaching management.

BACKGROUND:Reconstruction of the anterior cruciate ligament has become the gold-standard treatment for an anterior cruciate ligament rupture. Despite the popularity of the procedure, there remains a considerable amount of controversies over whether an autograft or anal ograft should be used for primary anterior cruciate ligament reconstruction. OBJECTIVE:To compare the clinical outcomes of al ograft and autograft in primary anterior cruciate ligament reconstruction. METHODS:Randomized control ed trials concerning autograft versus non-irradiated al ograft for anterior cruciate ligament reconstruction were identified from the PubMed/Medline database conducted up to July 12, 2014. These studies were selected independently by two reviewers according to the inclusion and exclusion criteria. Meta-analysis was performed using Revman5.2 software. RESULTS AND CONCLUSION:A total of 6 randomized control ed trials consisting of 858 cases were included, 441 cases in autograft group and 417 cases in non-irradiated al ograft. The results of the meta-analysis indicate no significant difference between autografts and non-irradiated al ografts in overal IKDC [relative risk (RR)=1.02, 95%confidence interval (CI) (0.99 to 1.06), P=0.21], degree of laxity [mean difference (MD)=-0.13, 95%CI (-0.29 to-0.02), P=0.09], Lachman test [RR=1.04, 95%CI (0.95 to 1.13), P=0.37], pivot shift test [RR=1.00, 95%CI (0.95 to 1.05), P=0.96], one-leg hop test [RR=1.01, 95%CI (0.96 to 1.06), P=0.77], Lysholm score [MD=-0.64, 95%CI (-1.45 to 0.17), P=0.12], Tegner score [MD=0.16, 95%CI (-0.16 to 0.47), P=0.34] and rate of postoperative complications [RR=1.42, 95%CI (0.67 to 3.04), P=0.36]. Therefore, in the meta-analysis, there is no significant difference between autograft and non-irradiated al ograft in clinical outcomes. However due to the limitations of our study, further work is needed to determine this conclusion.

A 54-year-old female patient with congenital heart disease had a persistent complete left bundle branch block three months after closure by an Amplatzer ventricular septal defect occluder. Nine months later, the patient suffered from chest distress, palpitation, and sweating at daily activities, and her 6-min walk distance decreased significantly (155 m). Her echocardiography showed increased left ventricular end-diastolic diameter with left ventricular ejection fraction of 37%. Her symptoms reduced significantly one week after received cardiac resynchronization therapy. She had no symptoms at daily activities, and her echo showed left ventricular ejection fraction of 46%and 53%. Moreover, left ventricular end-diastolic diameter decreased 6 and 10 months after cardiac resynchronization therapy, and 6-min walk dis-tance remarkably increased. This case demonstrated that persistent complete left bundle branch block for nine months after transcatheter closure with ventricular septal defect Amplatzer occluder could lead to left ventricular enlargement and a significant decrease in left ventricular systolic function. Cardiac resynchronization therapy decreased left ventricular end-diastolic diameter and increased left ventricular ejection fraction, thereby improving the patient’s heart functions.
