OBJECTIVETo observe the relation between Pi deficiency syndrome (PDS) and the configuration and functions of extensor digitorum longus (EDL)and soleus (SOL).

METHODSTotally 36 ICR mice were randomly divided into 3 groups according to weight matching principle, the control group, the exhausted group, and the rhubarb group, 12 in each group. Two PDS models were established by either purgation with rhubarb diarrhea (as Group A) or exhausted swimming plus sleep deprivation (as Group B).The cross sectional area (CSA) of type I and II fibers of extensor digitorum longus (EDL) and soleus (SOL), relative proportions of type I and II fibers were measured by m-ATPase histochemical method. The isotonic contraction and the maximum tetanus contraction of EDL and SOL were detected by PowerLab system.

RESULTSCompared with the control group, the body weight, body temperature, and the general health condition of PDS model rats obviously decreased; the spleen index and the thymus index were also lower; the maximal isotonic contraction and the maximum tetanus contraction obviously decreased; the cross section areas of EDL and SOL were reduced with loosely arranged cells. In EDL, the proportion of type I fibers was added and the proportion of type II fibers was lowered. In SOL, there was no change in the proportion of type I and type II fibers.

CONCLUSIONSEDL and SOL were obviously atrophied in the two PDS model mice. The type I fibers of SOL was more significantly atrophied in Group B.

This study aimed to investigate viral infections and the prevalence of influenza-like illness (ILI) in Shijiazhuang, China, in 2011 and to provide a scientific basis for the diagnosis and control of respiratory tract infections. Throat swab specimens were collected from 483 cases of ILI who were outpatients in the influenza surveillance sentinel hospitals in Shijiazhuang between January and December 2011. All specimens were examined by multiplex RT-PCR for the following 15 respiratory tract viruses: adenovirus (ADV), human rhinovirus (HRV), human parainfluenza virus (PIV types 1-4), influenza virus A (FluA), influenza virus B (FluB), human enterovirus (HEV), respiratory syncytial virus (RSV-A and -B), human metapneumovirus (HMPV), human coronavirus (HCoV-229E/NL63 and -OC43/HKU1), and human bocavirus (HBoV). Among the 483 cases of ILI, 214 (44.31%) were positive for viruses, including ADV (8.7%), HEV (8.7%), RSV-A (8.07%), HRV (7.45%), FluA (5.38%), HCoV-OC43/ HKU1 (2.9%), PIV-3 (2.9%), HMPV (1.86%), PIV-1 (1.24%), HCoV-229E/NL63 (1.04%), PIV-2 (1.04%), HBoV (0.83%), and FluB (0.41%). Twenty-six (5.38%) of all cases were co-infected with two or more viruses, most commonly HEV/HRV with other viruses. Cases of viral infection were detected throughout the year, with peaks in January and February. ADV and HRV were detected throughout almost the whole year without obvious seasonality. HEV was detected between April and November, with a peak of prevalence in summer and autumn. FluA and FluB reached epidemic levels mainly in winter and spring. All cases of RSV were identified to be subtype A. PIV infection was mainly caused by PIV-3. The positive rate of HCoV-OC43/HKU1 infection was significantly higher than that of HCoV-229E/NL63. The leading five viruses that resulted in ILI Shijiazhuang in 2011 were HEV, ADV, RSV-A, HRV, and FluA, and these viruses have different epidemiological features.

Objective To investigate the diagnostic value and significance of myocardial injury markers in neonates.Methods A retrospective analysis of 838 cases of myocardial injury markers in neonates,the total positive rate of hs -cTnI and the positive rates of hs -cTnI(hypersensitivity cardiac troponin I)in different kinds of neonatal disease were calculated,the levels of abnormalities consistent rate in hs -cTnI and CK -MBmass(creatine kinase MB mass)were compared with hs -cTnI and MYO(Myoglobin).Results The total positive rate of hs -cTnI was 40.33% in the 838 neonates.The highest incidence of myocardial injury was neonatal sepsis (57.14%),followed by neonatal pulmonary hemorrhage (55.56%)and neonatal convulsions (54.55%).The abnormalities consistent rate of hs -cTnI and CK -MBmass was better than hs -cTnI and MYO (85.50% vs 28.11%,χ2 =226.9,P <0.05). Conclusion Neonatal hospitalized children often complicated by myocardial injury;As a biochemical myocardial injury marker,the hs -cTnI detection is important for early detection of myocardial injury,it should be recommend as routine test items;CK -MBmass has better correlation with hs -cTnI than MYO,which can provide guide for doctors to interpret the data of myocardial injury markers.

Objective To improve the effect of clinical diagnosis and treatment of acetabular fracture with a femoral nerve injury by analyzing the causes of femoral nerve injury following acetabular fractures.Methods From January 1996 to November 2004,146 cases of acetabular fractures were treated operatively.Six cases of them were complicated with femoral nerve injury.The causes of femoral nerve injury were analyzed on the basis of clinical manifestations,CT scan and 3-dimensional reconstruc- tion.All the cases were classified according to Letournel and Judet classification.Three cases had hema- toma compression (2 cases with double column fractures and 1 with transverse-posterior wall fractures);2 cases had femoral nerve injury caused by fracture fragments (1 case with anterior wall fracture following anterior hip dislocation,the another with old fracture of anterior column combined with fracture of superior ramus of pubis);and one case had anterior column fracture combined with fracture of wing of ilium,and the femoral nerve was injured by traction in operation.Clearance of hematoma,nerve tract decompression and epineuria solution were performed in 5 cases,and 1 case was treated conservatively.Results The average follow-up period was 1.8 years(ranging from 1 to 3 years).The muscle power of quadriceps fem- oris recovered from 1-2 grade before operation to 4-5 grade after operation in 5 cases.The function of ex- tensor knee and gait was normal.The function of sensory completely recovered in 4 cases.One case was followed up for 2 years,which showed the patient still suffered from hypoesthesia in the lower 2/3 of the thigh and the medial of the leg.One ease of traction injury was followed up for 1.2 years,showing the muscle power recovered to normal,but still presented with sensory disability.Conclusion Acetabular fractures associated with femoral nerve injury are rare.For complex acetabular fractures and severe trau- ma,attention should be given to the possibility of femoral nerve injury.Fragment stabbing and compres- sion of hematoma around iliopsoas muscle are the common causes of femoral nerve injury following ace- tabular fractures.Iatrogenic injury should not be ignored.

OBJECTIVETo observe the effect of single herb pilose antler (PA) on the expression of Smad2 and Smad3 in the cartilage of osteoarthritis (OA) rats.

METHODSOne hundred 3-month old female healthy SD rats, (200 +/- 20) g, were recruited and routinely fed for 1 week. They were randomly divided into 5 groups, i.e., the low dose PA group, the high dose PA group, the normal saline control group, the model group, and the normal control group, 20 in each group. The model was prepared using classic Hulth method except the normal control group. After 6-week modeling, the model was confirmed successful by pathologic observation. PA at 0.021 g/100 g and 0.084 g/1 00 g was given by gastrogavage to rats in the low dose PA group and the high dose PA group respectively. Normal saline was administered to those in the normal saline control group. No treatment was given to rats in the normal control group and the model group. Bilateral knee cartilages were harvested at week 2,4, and 6. mRNA and protein expressions of Smad2 and Smad3 were detected by immunohistochemical assay, fluorescent quantitative PCR, and Western blot.

RESULTSOA model was successfully prepared by pathological observation. Results of immunohistochemical assay showed that Smad2 and Smad3 expressed extensively in the cartilage, and located inside the chondrocyte membrane. Compared with the model group, mRNA expression of Smad2 and Smad3 obviously increased in the low dose PA group and the high dose PA group at week 2, 4, and 6, showing statistical difference (P < 0.05). Compared with the same group at week 4 after gastrogavage, mRNA expression of Smad2 and Smad3 obviously decreased in the low dose PA group and the high dose PA group at week 6, showing statistical difference (P < 0.05). Compared with the model group, protein expression of Smad2 and Smad3 obviously increased in the chondrocytes of the low dose PA group and the high dose PA group at week 2 and 4, showing statistical difference (P < 0.01). Compared with the same group at week 2 after gastrogavage, protein expression of Smad2 and Smad3 obviously increased in the low dose PA group and the high dose PA group at week 4, showing statistical difference (P < 0.01). Compared with the same group at week 4 after gastrogavage, protein expression of Smad2 and Smad3 obviously decreased in the low dose PA group and the high dose PA group at week 6, showing statistical difference (P < 0.01).

CONCLUSIONS(1) The pilose antler could repair cartilages by regulating mRNA and protein expressions of Smad2 and Smad3. (2) Up-regulating mRNA and protein expressions of Smad2 and Smad3 might be one of important mechanisms for the pathogenesis of OA.

OBJECTIVESubtrochanteric femoral fractures are severe injuries. Although many treatment methods have been developed, controversy exists regarding the optimal management of these fractures. This study evaluated the clinical outcome of subtrochanteric femoral fractures fixed with long proximal femoral nail antirotation (PFNA-long).

METHODSBetween October 2006 and February 2008, 25 patients with traumatic subtrochanteric fractures of the femur were treated with PFNA-long. Closed reduction and fixation were performed in 20 cases. In the remaining 5 cases, closed reduction was difficult, so limited open reduction was performed, with bone grafting in 4 cases and circumferential wiring in 4 cases.

RESULTSThe average follow-up time was 16.1 months. All subtrochanteric femoral fractures healed uneventfully except one case of delayed union. The mean union time was 26.2 weeks. Technical difficulties with nail insertion were encountered in 3 cases. No implant failure was observed.

CONCLUSIONPFNA-long is effective in treatment of subtrochanteric femoral fractures, with a high rate of bone union, minor soft tissue damage, early return to functional exercise and few implant-related complications.

PURPOSETo investigate efficacy of open reduction and internal fixation with the miniplate and hollow screw in the treatment of Lisfranc injury.

METHODSTen cases of Lisfranc injury treated by open reduction, miniplate and hollow screw in our hospital were retrospectively analyzed. There were 6 males and 4 females with age ranging from 25 to 45 years (mean 32 years). Among them, one case was classified as Type A, six Type B and three Type C. Injury mechanism included road traffic accidents (3 cases), fall from height (5 cases) and hit by heavy object (2 cases). All injuries were closed without cerebral trauma or other complicated injuries. The time interval between injury and operation was 6-10 days (average 6.6 days). Postoperatively, the foot function was assessed using Visual Analogue Scales (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) Scales. Healing time and complications were observed.

RESULTSAll patients were followed up for 18-24 months (average 20 months). Anatomic reduction was achieved in all patients on images. There was statistical significance between preoperative score (7.89 ± 0.34) and score at postoperative 8 weeks (0.67 ± 0.13). According to the AOFAS score, 5 cases were defined as excellent, 3 cases as good and 2 cases as fair. During follow-up, there was no wound infection or complications except for osteoarthritis in 2 cases. Healing time ranged from 3 to 6 months with an average of 3.6 months.

CONCLUSIONAnatomical reduction of Lisfranc injury can be achieved by open reduction and internal fixation with the miniplate and hollow screw. Normal structure of Lisfranc joint is regained to a great extent; injured ligaments were also repaired. Therefore, this method offers excellent curative effect and can avoid postoperative complications and improve the patients' quality of life.

OBJECTIVETo study lymph node micrometastases (LNMM), expression of nm23-H(1), MMP(9), TIMP(2) proteins, and their relationship and clinical significance in patients with stage Dukes B colorectal cancer.

METHODSThirty patients with stage Dukes B colorectal cancer were studied. LNMM in these patients was detected by immunohistochemical anti-cytokeratin 20 (CK20) staining. The expression of nm23-H(1), MMP(9) and TIMP(2) proteins in primary tumors was examined by Strept-avidin-biotin complex method. Clinical-pathological data and survival of each patient were recorded and analyzed.

RESULTS(1) The positive dyeing of CK20 was observed in 26.7% for cases and in 7.8% for lymph nodes of 30 patients with stage Dukes B colorectal cancer. (2) Different expression of nm23-H(1) and MMP(9) proteins in the patients between stage Dukes B and stage Dukes CD was observed (P < 0.05). The decreased nm23-H(1) expression, and/or the increased MMP(9) expression in primary stage Dukes B tumors were significantly associated with LNMM (P < 0.05). Sensitivity and specificity for detection of LNMM by using nm23-H(1) or MMP(9) were respectively 62.5% and 81.8% or 75.0% and 69.8%. If by combining nm23-H(1) with MMP(9), specificity for detection of LNMM became 90.9%. The expression of TIMP(2) protein was not related with stage Dukes and LNMM. (3) The percent of tumor recurrence and/or metastasis for the stage Dukes B patients with LNMM was significantly higher than that for the patients without LNMM (P < 0.05), but the survival percent for the patients with LNMM was significantly lower than that for the patients without LNMM. The outcome for the patients with nm23-H(1) (-) LNMM (+) or MMP(9) (+) LNMM (+) was significantly worse than that for patients with nm23-H(1) (+) LNMM (-) or MMP(9) (+) LNMM (-) (P < 0.05).

CONCLUSIONSLNMM is detected by immunohistochemical anti-CK20 staining. The expression of nm23-H(1) and MMP(9) in primary stage Dukes B tumors was significantly associated with LNMM. The outcome in the LNMM patients with nm23-H(1) (-) and/or MMP(9) (+) were worse. Combining examination of CK20 for lymph nodes with expression of nm23-H(1) and MMP(9) for primary tumors is of important clinical significance for staging of Dukes, selection of adjuvant treatment and evaluation of prognosis in patients with colorectal cancer.
