Objective To investigate the changes of serum cardiac troponin I(cTnI)and brain natriuretic peptide(BNP)in heart failure of children with pneumonia and their relationship with heart function.Methods Thirty healthy children aged from 5 months to 3 years old were randomly selected with 17 male and 13 female(healthy group).Thirty children with severe heart failure aged from 3 months to 2 years old were selected at the same time with 21 male and 9 female(heart failure group).Thirty children with ordinary pneumonia aged from 3 months to 3 years old were also sampled with 16 male and 14 female(ordinary pneumonia group).The peripheral bloods of 2-3 mL of all children were taken.The BNP level were measured by enzyme-linked immunosorbent assay and the cTnI level was determined by micro-particle enzyme immunoluminescent.Left ventricular ejection fraction(LVEF) and left ventricular fractional shor-tening(LVFS)were detected by echocardiography.SPSS 11.0 software was used to analyze the data.Results The levels of cTnI [(0.389?0.030) ?g/L] and BNP [(0.572?0.090) ?g/L] of heart failure group increased significantly compared with healthy and ordinary pneumonia group,while their LVEF and LVFS decreased significantly(Pa

BACKGROUND: With the aging of population, brittle fracture diseases have attracted more and more attention from clinicians. Bone mineral density detection cannot meet the risk assessment of brittle fracture. As one of the new directions and methods to evaluate the risk of brittle fracture, cortical thickness has been studied and discussed by more and more scholars. OBJECTIVE: To explore the correlation of bone cortical thickness values and X-ray gray values in different planes of proximal femur with hip brittle fracture in women aged over 50 years old under X-ray DR photography, so as to evaluate the most appropriate measurement plane for predicting the risk of hip brittle fracture in women among different planes of proximal femur. METHODS: According to the inclusion criteria, relevant clinical data of 100 female patients aged over 50 years old who underwent X-ray DR pelvic radiograph examination at Department of Radiology of the Ninth Affiliated Hospital of Guangxi Medical University from July 2018 to June 2019 were collected. All patients signed the informed consents and the study was approved by the ethics committee of the hospital. The measurement planes of cortical thickness of the proximal femur were designed to be the middle part of femoral neck, within 1 cm above the lesser trochanter, and within 1 cm below the lesser trochanter, with a total of three groups of measurement planes. The gray value of X-ray was measured by taking the line between the middle point of the great rotor and the small rotor as the rectangular diagonal line to take the rectangular area for measurement. RESULTS AND CONCLUSION: (1) Women aged 50-64 years were as group A (n=50) and those aged 65 years and older were as group B (n=50). (2) The cortical thickness and X-ray gray value within 1 cm below the lesser trochanter, and within 1 cm above the lesser trochanter in the group B were significantly lower than those in the group A; fracture rate was higher in group A than in group B (P < 0.05). There was no significant difference in the cortical thickness of middle part of the femoral neck between two groups (P > 0.05). (3) On the whole, cortical thickness values were highest in the within 1 cm below the lesser trochanter, followed by within 1 cm above the lesser trochanter and lowest in the middle part of the femoral neck (P < 0.05). (4) The correlation coefficient of cortical thickness and X-ray gray value of the within 1 cm below the lesser trochanter and within 1 cm above the lesser trochanter and age to brittle fracture was -0.303, -0.205, -0.272, and 0.346 (P < 0.05). There was no significant correlation between cortical thickness of middle part of the femoral neck and brittle fracture (P > 0.05). (5) The difference of cortical thickness within 1 cm below the lesser trochanter and within 1 cm above the lesser trochanter between fracture and non-fracture groups in the group A was significant (P < 0.05). There was no significant difference in each index between fracture and non-fracture groups in the group B (P > 0.05). At the age above 50 years, the difference of cortical thickness and X-ray gray value in each measured plane between fracture and the non-fracture groups was significant (P < 0.05). (6) To conclude, the cortical thickness becomes thinner and the gray value of X-ray becomes smaller, and the possibility of brittle fracture of hip becomes higher. When assessing the risk of hip fracture in women aged over 50 years using cortical thickness of the proximal femur, measurement within 1 cm below the lesser trochanter is recommended.

BACKGROUNDGastric cancer (GC) is the second leading cause of cancer mortality worldwide, and surgical resection is currently the only possible curative approach. Duodenal stump leakage is the most serious complication after radical gastrectomy, and optimal treatment is still lacking.

METHODSWe retrospectively reviewed 2034 cases of total or subtotal gastrectomy for GC from January 1995 to December 2009, including 465 cases of duodenal stump closure using purse-string suture (group A), 835 cases of duodenal stump treated with linear cutting stapler and seromuscular layer suture (group B), and 734 cases of duodenal stump closure using full-thickness and seromuscular layer suture (group C). We evaluated the surgical cost, operative time for duodenal stump closure, short-term postoperative complications, perioperative blood loss, and postoperative recovery.

RESULTSThere was no perioperative mortality in any group. Ninety-four postoperative (within 1 month) complications occurred: 18 abdominal bleeding, 14 anastomotic leakage, 15 abdominal infection, 36 wound infection, and 11 duodenal stump leakage. There was no significant difference among the groups in intra-abdominal hemorrhage, anastomotic leakage, abdominal infection and wound infection. No postoperative duodenal stump leakage occurred in group A, which had a significant difference compared with groups B and C (6 cases in group B and 5 cases in group C suffered duodenal stump leakage. P < 0.01). The surgical cost in groups A and C was significantly lower than in group B (P < 0.01), with no significant difference between groups A and C. The processing time for duodenal stump closure in groups A and B was significantly shorter than in group C (P < 0.01), with no significant difference between groups A and B. There was no significant difference in blood loss and postoperative recovery among the groups.

CONCLUSIONSDuodenal stump closure using purse-string suture seems to be a promising approach with shorter operative time, and lower cost and incidence of duodenal stump leakage in radical gastrectomy.

OBJECTIVETo study the clinical effectiveness of implanting miniscrew serving as anchorage instead of molars in treating maxillary dental arch crowding and protrusive patients mandibular molars complete missing.

METHODSEight adult patients aged from 22 to 38, whose maxillary dental arch were crowding and protrusion, with mandibular molars missing were chosed. At the missing side, a miniscrew was implanted on the buccal surface, 11-13 mm away from the distal end of the second premolar. After implanting, a self-made miniscrew traction cap was attached to its supergingival section by keyway retention. Premolars and anterior teeth were tracted in turn to distal end. Intermaxillary traction II was made necessarily on the traction cap.

RESULTSSuccessful results were acquired after treating together with normal overbite, overjet and right occlusion relation. It took 24 months in the longest course, 15 months in the shortest course and 20.8 months on average.

CONCLUSIONThe implanting miniscrew anchorages could be used in maxillary dental arch crowding and protrusive patients with single molars complete missing.

OBJECTIVETo investigate the association of SOX9 expression and clinicopathologic factors and prognosis of gastric cancer.

METHODSA retrospective cohort study including 112 gastric cancer patients admitted to the Zhejiang Provincial People's Hospital from 2004 to 2006 was performed. Immunohistochemical analysis was used to evaluate the expression of SOX9 in the 112 specimens of gastric cancer tissues and 70 non-cancerous tissues adjacent to the tumor.

RESULTSLow expression of SOX9 was seen in 5(7.1%) tissues out of 70 non-cancerous tissues adjacent to the tumor. A total of 94(83.9%) patients had varying expression of SOX9, of whom 51(45.4%) had overexpression. Univariate analysis demonstrated that the expression of SOX9 was significantly associated with Lauren classification (P<0.05), tumor invasion(P<0.01), lymph node metastasis(P<0.05), distant metastasis(P<0.05) and tumor stage(P<0.05), however there was no significant association between SOX9 expression and sex, age, histological type, histology differentiation or tumor size. Kaplan-Meier analysis showed that the 5-year survival rate of patients with SOX9 over-expression was significantly lower than that of patients with low expression(29.4% vs. 49.2%, P=0.031). Multivariate Cox regression analysis showed that histology differentiation(P=0.046), tumor invasion(P=0.001), and distant metastasis(P<0.01) were independent prognostic factors for gastric cancer, however the over-expression of SOX9 was not significant(P=0.948).

CONCLUSIONSThe expression SOX9 is associated with the growth, invasion, and metastasis of gastric cancer, as well as the prognosis. However, SOX9 expression is not an independent factor for the prognosis in patients with gastric cancer.

OBJECTIVECompletion pneumonectomy (CP) is widely known to be associated with a high morbidity and mortality. However, in certain instances, CP offers the only chance for a cure. Now to explore the indications, prevention and management of complications as well as late outcomes of CP.

METHODSDuring a period of 21 years from January 1985 to August 2006, 24 patients received CP, representing 2.3% of 1026 patients who had undergone pneumonectomy in the same period. There were 17 right and 7 left CPs done in 20 male and 4 female patients with an average age of 58 years (range from 42 to 67 years). Lung malignancy accounted for 22 of these cases in which the indication included local recurrence in 18, second primary tumors in 2 and primary malignancies that developed after right upper lobectomies for pulmonary tuberculoma and pulmonary cyst respectively in 2 cases. Benign disease was progression or recurrence of bronchiectasis in 2 cases. Before CP, 17 patients had had a lobectomy, 5 a bilobectomy, 1 sleeve lobectomy and 1 wedge resection. There were 16 of 20 lung cancer patients receiving postoperative chemotherapy and 3 with positive residues having radiotherapy. The mean interval between the two procedures was 65 months for the whole group (5.5-360) and 32 months for lung cancer patients (5.5-120). They all underwent CP, included sleeve CP in 1 patient.

RESULTSFor all patients, the previous thoracotomy incision was reopened and maneuvers such as rib resection, intrapericardial blood vessel ligation, division of the bronchus first, local application of glues and hemostatic agents, and bronchial reinforcement were routinely used. Intrapericardial route was used in 10 patients (41.7%). Two patients had right pulmonary artery injured. The operation lasted 4-7 hours, with blood loss of 300 to 3000 ml. Overall respectability, morbidity and hospital mortality were 95.8%, 29.2% and 4.2%. No intraoperative deaths occurred. There was 1 early postoperative death after 40 days from adult respiratory distress syndrome. There was no occurrence of bronchopleural fistula, and the 25% associated morbidity rate was a result of bleeding necessitating reexploration in 1 case, chronic empyema in 1 case, arrhythmia in 1 case, anemia in 1 case and fever of unknown reason in 2 cases. Actuarial 1-, 3-, 5-year survival rates from the time of completion pneumonectomy for patients with lung cancer were 77.3%, 50.0% and 29.4%. And 1-, 3-, 5-year survival rates for patients with recurrent lung cancer were 72.2%, 47.1% and 29.4%.

CONCLUSIONSCP can be performed with an acceptable operative mortality and morbidity rate in selected patients. For patients with local recurrence, first and second primary bronchogenic carcinoma as well as benign pulmonary disease, treatment should be surgical when a less invasive procedure is not available and the patients are in good health. In addition, patients undergoing CP have a reasonable prospect for long-term survival.

Objective:To investigate the safety and efficacy of two methods for urethral catheterization in patients with benign prostatic hyperplasia and acute urinary retention after failure of routine indwelling catheterization.Methods:This was a randomized controlled study. From January 2020 to December 2021, 80 patients with benign prostatic hyperplasia complicated with acute urinary retention who failed of catheterization by conventional methods in the Department of Urology, Beijing Aerospace General Hospital were divided into observation group and control groupaccording to the random number table method, with 40 patients in each group. The observation group used a 12 Fr silicone Foley catheter, which was folded 2 cm in front of the catheter. The control group used a 16 Fr silicone curved Coudé catheter. The success rate of catheterization, catheterization time, incidence of gross hematuria after catheterization, and Visual Analog Scale (VAS) were compared between the two groups.Results:The success rate of catheterization in the observation group was 82.5% (33/40), which was significantly higher than 62.5% (25/40) in the control group, and the difference was statistically significant ( χ2 = 4.01, P<0.05). There was no significant difference in the incidence of gross hematuria, the time of catheterization from urethra into bladder and VAS between the two groups (all P>0.05). Conclusions:Technique for manipulating a 12 Fr catheter before insertion into urethral meatus in a difficult catheterization has high success rate and not significantly increases the side effects in patients with benign prostatic hyperplasia with acute urinary retention after failure of routine indwelling catheterization.

BACKGROUNDAssessment of lymph node metastasis (LNM) is important in early gastric cancer (EGC) and affects treatment decisions. However, the relationship between clinicopathological characteristics and LNM in EGC remains unclear. This study therefore explored favorable predictors of LNM in EGC.

METHODSA total of 716 specimens from gastric cancer patients who underwent curative gastrectomy between 1996 and 2003 at Zhejiang Provincial People's Hospital were reviewed. Forty-five cases were EGC, and clinicopathological characteristics such as gender, age, tumor size, location, gross type, differentiation, invasion depth, and vessel involvement were assessed to identify predictive factors for LNM and survival time.

RESULTSThe overall cumulative 5-year survival rate of EGC patients was 88.92%. Among these, 22.4% developed LNM, which was associated with a poor 5-year survival rate of only 72.7%. Patients with tumors larger than 2 cm in diameters, with depth of tumor invasion to the submucosa, and with positive lymphatic or nerve involvement were also inclined to have poorer survival performances. EGC limited to the mucosa but poorly differentiated also had a high risk for LNM. Multivariate analysis identified lymphatic invasion and tumor size as independent prognosis factors related to survival in EGC patients.

CONCLUSIONSCareful planning is required in EGC patients at high risk of lymph node metastases. Endoscopic mucosal resection or endoscopic submucosal dissection and laparoscopic partial gastrectomy should be cautiously used in EGC, and curative gastrectomy including lymphatic dissection and postoperative adjuvant therapy might be considered to improve the prognosis.
