OBJECTIVETo explore early clinical effect of acetabular cup in total hip replacement for the treatment of Crowe II developmental dysplasia of hip.

METHODSEighteen patients (18 hips) with Crowe type II developmental dysplasia of hip were treated with total hip replacement from September 2001 to July 2013. Among them,including 13 males and 5 females aged from 42 to 60 years old with an average of 47.6 years old; the courses of diseases ranged from 9 to 22 years with an average of 13.5 years. All the patients had hip joint pain, limb shortening and limited hip function before operation. Harris score of hip joint were used to evaluate recovery of function at 1 day and 12 months after operation. Prosthetic coverage of acetabular cup at 1 week after operation was observed by using radiography.

RESULTSEighteen patients (18 hips) were followed up from 12 to 24 months with an average 17 months. All incisions were healed at stage I. No deep vein thrombosis, hip dislocation, periprosthetic joint infection and prosthesis loosening were occurred. No revision surgery during follow-up period. Prosthetic coverage of acetabular cup was more than 80% at 1 week after operation. Harris score were increased from 42.67 ± 5.06 before operation to 94.79 ± 3.27 at 12 months after operation (t = -45.269, P < 0.001).

CONCLUSIONFor type Crowe II developmental dysplasia of hip patients, 15° face-changing acetabular cups in THR could obtain higher actebular component coverage rate and satisfactory early clinical effects.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.

OBJECTIVETo investigate the complications of surgical treatments for femoral intertrochateric fractures using dynamic hip screw (DHS).

METHODSFrom Jan. 2002 to Dec. 2007, sixty-nine patients with intertrochanteric fractures were treated by dynamic hip screw fixation included 27 males and 42 females,with an average age of 72.9 years ranging from 53 to 96 years. According to Evans classification there were 10 cases in type I ,21 in type II, 22 in type III, and 16 in type IV, of which 51 patients (73.9%) suffered from systematic diseases preoperatively.

RESULTSFifty-seven patients were followed up for 8 to 70 months (41 months on average). Four patients died, 17 cases occurrenced systematic complications postoperatively. Internal fixation related complications occurred in 12 patients. There were 8 cases with mechanical failure of DHS including 4 of screw loosen,3 of cutting-out of device through femoral head and neck and 1 of plate breakage. Five patients had a coxa vara, and delayed union occurred in 4 patients.

CONCLUSIONUnstable fracture pattern produced high percentage of mechanical failure. In such cases DHS should not be the first choice for treatment. The appropriate treatment should be in relation to pre-operative fracture stability and osteoporosis.

OBJECTIVETo study the relationship of expression of mucin 1 and E-cadherin with recurrence of pleomorphic adenoma in salivary gland, and to investigate the signal to predict the recurrence potential of the tumor.

METHODS; The capsule of tumor was observed by microscope. The expression of mucin 1 and E-cadherin in 33 cases of primary adenoma, 12 cases of recurrent pleomorphic adenomas and 7 cases of malignant pleomorphic adenomas were detected by immunohistochemistry.

RESULTSThere was no significant difference about the status of capsule and the positive rate of mucin 1 expression between primary and recurrent pleomorphic adenoma (P > 0.05). The abnormal distribution of mucin 1 expression was observed in recurrent pleomorphic adenoma (6/8), which was characterized by the positive staining of the whole cytomembrane. On the other hand, positive staining of the primary pleomorphic adenoma was observed on the top of the membrane (19/21). The difference was statistically significant (P < 0.05). The staining pattern in malignant pleomorphic adenoma was similar with the recurrent ones except higher ratio of positive expression. No significant different was observed among the three kind of tumors on the expression rate of E-cadherin (P > 0.05).

CONCLUSIONThe status of capsule didn't have much actual usage in predicting the recurrence of pleomorphic adenoma. There was no significant relationship between the expression of E-cd and the recurrence of the tumor. The abnormal distribution of mucin 1 expression contributes to the invasiveness of the tumor and can be used as the predictive signal for recurrence of pleomorphic adenoma.

OBJECTIVETo investigate the influence of the amount of portal blood stasis removal on endotoxemia and liver function after liver transplantation.

METHODSForty-seven patients who received liver transplantation from February 2006 to November 2007 were divided into 2 groups according to the amount of portal blood stasis removal during operation: group A (n = 26) 50 ml and group B (n = 21) 200 ml of portal blood stasis removal respectively. The levels of plasma endotoxin, D-lactate, tumor necrosis factor-alpha, interleukin-6, liver function and blood coagulation were examined and analyzed.

RESULTSUnder the condition of no significant difference in sex, age, primary liver diseases and Child-pugh's classification, cold ischemic time, total operation and anhepatic time, operation methods, volume of blood loss and transfusion, and all preoperative observations. Most of observations showed the restoration of the patients in group B was better than that in group A. The plasma levels of endotoxin, D-lactate, tumor necrosis factor-alpha, interleukin-6, alanine aminotransferase, aspartate aminotransferase, prothrombin time and activated partial thromboplastin time in group B were significantly lower than those in group A (P < 0.05). The level of plasma prealbumin in group B was significantly higher than that in group A (P < 0.05).

CONCLUSIONSThe removal of 200 ml portal blood stasis leads to a better results than that of 50 ml, and it can help alleviate endotoxemia and facilitate the restoration of the liver function after liver transplantation.

OBJECTIVETo evaluate the efficacy and clinical outcome of the treatment of thoracolumbar single compression fracture by using in situ rod rotation reduction and short segment pedicle screw at the fracture level.

METHODSFrom December 2008 to May 2010,12 cases of traumatic thoracolumbar single compression fracture (T11-L2) were treated, including 9 males and 3 females, with an average age of 35.8 years old (ranging from 24 to 52). There were 2 case with T11 fracture, 2 cases with T12, 6 cases with L1 and 2 cases with L2, without osteoporosis,pathological fractures or neurologic deficits. Radiographic data were collected preoperatively, 5 days postoperatively and at last follow-up (at least 12 months). Cobb's angle, vetebral compression ratio, internal fixation state were observed.

RESULTSAll patients were followed up from 12 to 30 months postoperatively,with an average of 19 months. There was no pseudoarticulation and solid bone fusion was achieved in all cases. There were no complications such as loosening or rupturing of internal fixation and so on. Sagittal kyphotic Cobb angle was corrected from preoperative (25.8 +/- 9.4) degrees to postoperative (6.7 +/- 2.3) degrees and (6.9 +/- 2.6) degrees at last follow-up. The percentage of vertebral compression was corrected from preoperative (42.5 +/- 10.4)% to postoperative (7.5 +/- 3.9)% and (8.4 +/- 4.5)% at last follow-up.There was significant difference between the postoperative data and preoperative data (P < 0.05), while the difference was not significant between the postoperative data and the last follow-up (P > 0.05).

CONCLUSIONThe thoracolumbar single compression fracture can obtain and maintain a good restoration by using the technic of in situ rod rotation reduction and short segment pedicle screw at the fracture level. The technique should be highly recommended.

BACKGROUNDSepsis is a leading cause of death in the intensive care units. The late inflammatory cytokine, high-mobility group box 1 (HMGB1), plays a critical role in sepsis. In the present study, we investigated the association between the serum HMGB1 levels and the severity of organ injury in the lipopolysaccharide-induced sepsis in rats.

METHODSTo produce an animal model of sepsis with different degree of organ injury, animals were treated with three different doses of lipopolysaccharide (4, 8 and 16 mg/kg), and the animals in control group were treated with the same volume of the vehicle (saline). The levels of serum HMGB1 were measured at 0, 2, 4, 8, 16, 24, 32 and 48 hours after lipopolysaccharide (LPS) or vehicle injection, meanwhile the biochemical and histopathological indicators for the severity of organ injury were assessed.

RESULTSThe level of HMGB1 had a positive, high correlation with the abnormal changes of serum cardiac troponin I, alanine aminotransferase, aspartate aminotransferase, creatinine and blood urea nitrogen, as well as the pathologic scores of heart, lung, liver and kidney.

CONCLUSIONSThe level of serum HMGB1 is highly correlated with the severity of sepsis in rats, suggesting that HMGB1 could serve as a valuable adjunct in the diagnosis and management of sepsis.
