To discuss clinicopathological features and molecular genetic change of congenital mesoblastic nephroma (CMN).Methods Nine cases diagnosed as CMN were analyzed retrospectively in this study.Histological features,immunohistochemical profiles and ETV6 gene rearrangement status were assessed.Results All patients were within two years of age and eight of them were within one year.The average diameter of tumors was 9.5 cm (3.2-15.0 cm).These series cases included 3 classic CMN,5 cellular CMN and 1 mixed CMN.Cystic degeneration was found in 5 cases,and cartilage islands were observed in 2 cases.Compared with classic CMN,tumor size was bigger,and hemorrhage,necrosis and mitotic figures were easily to see in cellular CMN.All the tumor cells were positive for vimentin and negative for WT-1 by immunohistochemistry.ETV6 gene rearrangement was detected in 5 cases (including 4 cellular CMN and 1 classic CMN).Three cellular CMN harbored ETV6 gene translocation,1 mixed CMN and 1 cellular CMN were negative for ETV6 gene translocation by FISH analysis.The follow up data were obtained in 7 cases and 2 cases were lost.All the 7 patients were alive without evidence of recurrence and metastasis from 5 to 46 months.Conclusion CMN is a rare infant renal tumor with unique clinicopathological characteristics.Most of cellular CMNs harbor ETV6 gene translocation.The prognosis of CMN is relative good and needs to be differentiated from other malignant renal tumors.

OBJECTIVE To enhance the rational usage of antibiotics by comprehensive interventional measures in clinics.METHODS Several interventional measures have been adopted in our hospital since January 2001: to(establish) expert team on antibiotics usage and administration consultation;constitute antibiotics use criteria(suitable) for each clinical specialty;train and examine the usage of antibiotics;censor the distribution of pathogen and drug-resistance variance.Then 10% of the discharged medical records in 2000,2002 and 2004 were drawn out respectively to analyze the usage of antibiotics and the isolation of pathogen from nosocomial infection cases.(RESULTS) The proportion of the patients with prophylactic and remedial indications was increased remarkably((P

Objective To analyze the distribution and drug resistance of pathogens for bacterial infection after lung transplantation,so as to provide evidence for clinical prophylactic strategies postoperation and reasonable use of antibiotics.Method The bacterial distribution and drug resistance of 81 recipients after lung transplantation in our hospital were retrospectively analyzed from May 2009 to October 2012.The VITEK-32 full-automatic microbial identification system (Biomerieux,France)and its supplementary reagent were used for bacterial identification and drug sensitive test.The data were statistically analyzed by using the software SPSS 13.0.Result There were 67 cases of bacterial infection in the 81 recipients after lung transplantation and the infection rate was 82.72％ (67/81).The infection was caused by one kind of bacteria in 20 patients,two kinds of bacteria in 23 patients and multiple bacteria in 24 patients.157 strains pathogenic bacteria were produced,and the grampositive bacilli and the gram-negative bacilli accounted for 12.74％ and 87.26％ respectively.The most common pathogens for the bacterial infection were Acinetobacter baumannii,Klebsiella pneumoniae,Pseudomonas aeruginosa,Stenotrophomonasmaltophilia,Escherichia coli and Staphylococcus aureus.Most of the bacterial infections occurred in the early period (≤1 month) after lung transplantation and most non-fermentative bacterial pathogens were resistant to multi-antibiotics.Conclusion The bacterial infection rate is high after lung transplantation.The rational use of antibiotics in clinical practice should be adjusted according to the bacterial distribution and drug resistance.

OBJECTIVETo explore the clinical characteristic of functional articulation disorders in children and provide more evidence for differential diagnosis and speech therapy.

METHODS172 children with functional articulation disorders were grouped by age. Children aged 4-5 years were assigned to one group, and those aged 6-10 years were to another group. Their phonological samples were collected and analyzed.

RESULTSIn the two groups, substitution and omission (deletion) were the mainly articulation errors in these children, dental consonants were the main wrong sounds, and bilabial and labio-dental were rarely wrong. In age 4-5 group, sequence according to the error frequency from the highest to lowest was dental, velar, lingual, apical, bilabial, and labio-dental. In age 6-10 group, the sequence was dental, lingual, apical, velar, bilabial, labio-dental. Lateral misarticulation and palatalized misarticulation occurred more often in age 6-10 group than age 4-5 group and were only found in lingual and dental consonants in two groups.

CONCLUSIONMisarticulation of functional articulation disorders mainly occurs in dental and rarely in bilabial and labio-dental. Substitution and omission are the most often occurred errors. Lateral misarticulation and palatalized misarticulation occur mainly in lingual and dental consonants.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

OBJECTIVETo study the effect of occupational stress on cardiovascular function of different vocational population.

METHODSThe occupational stressors, risk factors of cardiovascular diseases were investigated by questionnaire in 839 people with 4 kinds of jobs. Blood pressure, sugar, and lipid were detected at the same time.

RESULTSBlood pressure were higher in the groups of old age, long standing and teachers, and the abnormal rate of blood pressure was 21.69%. There was no difference in abnormal ECG among ages, standing and occupation, and the abnormal rate of ECG was 19.07%. Job control, job demands, job responsibility, role in a job and shift work were the main stress factors affecting systolic and diastolic blood pressure. More conflict in job, less chance of participation, severe job loads were the risk factors of primary hypertension. Accident due to job responsibility, job responsibility, role in a job were the main risk factors of abnormal electrocardiograph. Self-respect and activity beyond work were the good modifiers of heart function.

CONCLUSIONOccupational stress has certain effect on cardiovascular function.

OBJECTIVELeptin (LEP) is mainly produced by white adipose tissue and participates in the energy metabolism and regulation of growth. Cooperating with the other metabolic hormones, it plays an important role in the developments of fetus and neonates. This study was designed to test the serum levels of LEP, neuropeptide Y (NPY), insulin (INS) and insulin-like growth factor-1 (IGF-1) and measure the body mass index (BMI) and head circumference (HC) at different days of life of premature infants with or without serious diseases and to find the changes of serum levels of LEP as well as NPY, INS and IGF-1, the relationship between those hormones and the changes of body weight and the influences of diseases on the levels of those hormones in premature infants.

METHODThe clinical data as well as weights, lengths, HC of 40 sick premature infants (sick group) and 30 premature infants without any diseases (control group) were collected and the serum levels of LEP, NPY, INS and IGF-1 were determined by using radioimmunoassay (RIA) at d 1, d 7 and d 12 of life. BMI was calculated by weight (kg)/length (m)(2). SPSS13.0 was used to analyze the data

RESULT(1) In sick group the serum LEP levels were 0.74 +/- 0.21, 0.60 +/- 0.18, 0.82 +/- 0.12 (mg/L) (P < 0.01), the BMI were 9.81 +/- 1.24, 8.36 +/- 0.87, 9.08 +/- 1.12 (kg/m(2)) (P < 0.01) on d 1, d 7 and d 12, respectively. In control group serum LEP levels were 0.78 +/- 0.17, 0.71 +/- 0.17, 0.88 +/- 0.58 (mg/L) (P < 0.01), the BMI were 10.03 +/- 1.04, 9.35 +/- 0.80, 11.06 +/- 0.82 (kg/m(2)), on d 1, d 7 and d 12, respectively (P < 0.01). In both groups, serum LEP levels as well as the BMI decreased on d 7 and reincreased on d 12. The differences of serum LEP levels and BMI between sick group and control group at d1 were not significant (P > 0.05); compared with control group, the serum LEP levels and BMI on d 7 and d 12 in sick group were lower and the differences were significant. (2) There were positive correlations between serum LEP levels and BMI in sick group as well as in control group. (3) In sick group, the serum NPY levels at d 1, d 7, d 12 were 55.33 +/- 9.38, 46.64 +/- 6.17, 75.13 +/- 9.12 (ng/L) (P < 0.01), INS were 10.07 +/- 2.63, 7.71 +/- 2.77, 10.37 +/- 2.29 (mU/L) (P < 0.01), IGF-1 were 38.66 +/- 11.42, 31.98 +/- 7.34, 41.84 +/- 8.05 (mg/L) (P < 0.01), respectively. In control group, the serum NPY levels at d1, d 7 and d 12 were 57.77 +/- 7.15, 48.49 +/- 8.81, 81.36 +/- 8.51 (ng/L) (P < 0.01), INS were 11.55 +/- 1.99, 8.28 +/- 2.87, 15.42 +/- 3.80 (mU/L) (P < 0.01), IGF-1 were 37.76 +/- 7.07, 34.33 +/- 8.97, 50.19 +/- 8.38 (mg/L) (P < 0.01), respectively. In both groups, serum levels of NPY, INS and IGF-1 had positive correlations with serum LEP levels as well as BMI on the corresponding days and decreased on d 7 and reincreased on d 12.

CONCLUSION(1) The serum LEP levels decreased on 7 d of life and reincreased on 12 d of life, which corresponded to the changes of the physical development of premature infants. (2) The serum LEP levels in sick premature infants decreased definitely as compared with control group, which suggested that diseases had negative influences on the LEP levels and the physical developments were slowed down in sick premature infants. (3) The serum levels of NPY, INS and IGF-1 had positive correlations with LEP levels as well as BMI at the early period of life, which suggested that NPY, INS and IGF-1, cooperating with LEP, might take part in the regulation of development of premature infants.

OBJECTIVETo summarize experience of using screws and cement to rebuild tibial bone defect in primary total knee arthroplasty (TKA) and to discuss the relationship between the number of required screws and the severity of tibial bone defects.

METHODSFrom July 2009 to May 2015, 34 patients (40 knees) with varus knees underwent TKA, and the screw and cement technique was used to rebuild medial tibia plateau during operation. There were 8 males (8 knees) and 26 females (32 knees), and the average age was (65.00 +/- 7.25) years old (ranged,55 to 82 years old). One to 6 screws were used in each case. Extension stems were used in 2 cases (4 and 5 screws was used respectively). The area percentages of the bone defects measured as defect area/tibia plateau area, depth of each defect, the number of screws needed in each case, were all used to determine the relationship between the number of screws and the area percentage in certain depth of bone defect by statistic methods, as well as the relationship between screw number and defect depth.

RESULTSAll the patients were followed up and the average duration was 24 months (ranged, 1 to 72 months). The average preoperative HSS score was 43.33 +/- 6.11 (ranged, 32 to 51 scores). Whereas the average postoperative HSS score was 92.15 +/- 4.64 (ranged,83 to 96 scores). The preoperative individual scores including pain, function, activity, nuscle strength, flexion deformity and stability were all improved compared with preoperation,and the differences were statistically significant. All the patients received normal alignment postoperatively, femoraltibial angle was improved from (167.00 +/- 6.39) degrees preoperatively to (175.00 +/- 2.69) degrees postoperatively, the tibial angle was improved from (78.09 +/- 4.51) degrees preoperatively to (88.75 +/- 1.24) degrees postoperatively. Both area percentage and depth of bone defect in a fitting Ologistic model had a significant statistical relationship with the screw number, and a rectangular coordinate system could be formed according to the relationship.

CONCLUSIONScrews and cement technique is a simple, safe and convenient method to rebuild tibial bone defects in primary TKA and its short-term and midterm effect are both reliable. During opera- tion, according to the rectangular coordinate system, the screw number needed in the operation can be inferred form th area and depth of tibia defect, which could have a guiding function in surgery.
