OBJECTIVETo explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation.

METHODSFrom January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group. In shoulder pain group, there were 21 cases including 15 males and and 6 females ranging the age from 22 to 62 years old with an average of (40.6±11.2) years old. There were 8 cases were on the left side and 13 cases were on the right side. In painless group, there were 65 cases including 36 males and and 29 females ranging the age from 19 to 65 years old with an average of (40.0±11.3) years old. There were 33 cases were on the left side and 32 cases were on the right side. The time from injury to operation ranged from 3 h to 8 d with an average of 34.6 h. Shoulder function of all patients were normal before injuried. Postoperative pain, activity of daily living (ADL), range of motion, deltoid muscle strength were compared. Anteflexion,rear protraction, abduction and upthrow of shoulder joint were also compared. Postoperative complications between two groups were observed and compared.

RESULTSAll patients were followed up from 12 to 48 months with an average of 18.5 months. Constant-Murley score were used to evaluate clinical efficacy at the least following up, and 13 cases got an excellent results, 5 moderate, 2 good and 1 poor in shoulder pain group ; while 61 cases were obtained excellent results, 3 moderate and 1 good in painless group. There were significantly differences between two groups in Constant-Murley score and activity of shoulder joint (P<0.05). In shoulder pain group, 3 cases were disconnected, 1 case occurred stress fracture, 9 cases were subacromial impingement syndrome, 5 cases occurred subluxation, 1 case occurred plate breakage and 11 cases were acromioclavicular arthritis.

CONCLUSIONChosing individual clavicular hook plate, fulfilling anatomic reset, paying attention to the repair of articular capsule ligament, and reducing hook and bone antagonism between stress is the key point of preventing and decreasing postoperative shoulder pain.

Objective To investiagte the serum adiponectin concentration in preeclampsia and its relationship with serum leptin and soluble leptin receptor levels.Method The level of adiponectin,leptin and soluble leptin receptor in serum were measured by enzyme-linked immunosorbent assay(ELISA)in 38 patients with preeclampsia and 42 patients as control.The relationship of free leptin index(leptin/soluble leptin receptor) to preeclampsia was analyzed.Results There were no significant differences in maternal age,gestational age and body mass index(BMI)between two groups.But the gestational age and birth weight were significantly lower in preeclampsia than in control.The patients with preeclampsia had significantly higher levels of serum adiponectin, leptin and free leptin index(1691.7?g/ml,37.5 ng/ml and 0.95 respectively)than the control(689.4?g/ml, 19.3 ag/ml and 0.49,respectively).But there was no significant difference in serum level of soluble leptin receptor between the groups(35.0 ng/ml vs 42.2 ng/ml).Serum adiponectin was not significantly correlated with the level of leptin,soluble leptin receptor and free leptin index.Area of serum adiponectin,leptin and free leptin index in preeclampsia under the ROC curve were less than 0.5.Conclusions The patients with preeclampsia have paradoxical higher serum levels of adiponecfin and more bioavailability of leptin,suggesting these may be important factom of this complication.

This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.

OBJECTIVETo investigate the clinicopathologic features of reactive hyperplasia of lymph nodes in maxillofacial regions.

METHODSThirty-two patients with lymph node reactive hyperplasia (LRH) were analyzed clinicopathologically including pathomorphologic manifestation and immunohistochemical expression.

RESULTSHistopathology of 32 patients showed significant hyperplasia in folliculus lymphaticus, marginal zone lymph, paracortical area lymph, and seldom mixed hyperplasia. Immunohistochemical study showed that the hyperplastic lymphocytes were mainly composed of CD20 positive B cells positive in 23 cases(72%), CD3 positive T cell in 7 cases (22%), CD20 positive T cell and CD3 positive B cell partially as well as histiocytes in 2 cases (6%). Atypical hyperplasia was found in 10 cases.

CONCLUSIONHyperplastic lymphocytes in LRH of maxillofacial regions are mainly composed of B cells. Malignant transformation may occur in these patients with atypical hyperplasia. Regularity follow up is necessary for these patients.

PURPOSE: The lessor saphenous vein is an anatomical index in various surgical methods involving an approach to the popliteal fossa. However, occasionally, there have been some cases where the surgical process was difficult because the lessor saphenous vein was not found in the popliteal fossa during the operation process. The aim of this study is to determine the frequency of the anatomical variation of lessor saphenous vein not found in the popliteal fossa with a review of the literature. MATERIALS AND METHODS: This study was conducted on 83 cases of selective neurectomy for hypertrophic calf performed in our clinic from March 1997 to June 2013. There were 42 patients, with a mean age of 32.8 years old. We confirmed the existence of the lessor saphenous vein in the popliteal fossa during the operation process. RESULTS: Among 83 cases during this study period, the lesser saphenous vein was not found in four cases. In one patient, no lesser saphenous vein was found on either side of the popliteal fossa, and in two patients, no lesser saphenous vein was found on the left side of the popliteal fossa. As a result, the frequency of variation was found to be 4.8%. CONCLUSION: Due to the anatomical variation of the lessor saphenous vein, it may not be found in the midline of the popliteal fossa. Based on the literature review, several possibilities for failure to observe the lesser saphenous vein could be suggested. If surgeons are well aware of these possibilities, the steadier operation could be performed.

OBJECTIVETo study the effects of minimal residual disease (MRD) level on day 33 of remission induction and IKZF1 genotype on the survival of children with B-lineage acute lymphoblastic leukemia (B-ALL).

METHODSA total of 152 children with newly-diagnosed B-ALL who had complete remission after the first cycle of the chemotherapy and had complete follow-up information were enrolled in this study. According to the MRD detection by flow cytometry on day 33 of remission induction, they were divided into three groups: standard-risk (SR) group (MRD <10; n=60), intermediate-risk (IR) group (10≤ MRD <10; n=55), and high-risk (HR) group (MRD ≥10; n=37). Nested RT-PCR was used to determine the IKZF1 genotype of all children before chemotherapy. The effects of MRD level on day 33 of remission induction and IKZF1 genotype on the recurrence-free survival (RFS) of children with B-ALL were analyzed.

RESULTSThere were 7 common IKZF1 subtypes in all the 152 children with B-ALL: IK1, IK2/3, IK4, IK6, IK8, IK9, and IK10. Of the 152 children, 130 had functional subtypes of IKZF1 and 22 had non-functional subtypes of IKZF1. During the follow-up period, relapse occurred in 26 (17%) children, and the recurrence rate was highest in the HR group (P<0.05). However, there was no significant difference in the recurrence rate between the SR group and the IR group (P>0.05). The cumulative recurrence rate of the children with non-functional subtypes of IKZF1 was significantly higher than that of those with functional types of IKZF1 (P<0.01). The predicted 5-year RFS rates in the SR, IR, and HR groups were (94.2±2.9)%, (86.7±3.8)%, and (56.2±4.5)% respectively (P<0.05). The 5-year RFS rate of the children with functional subtypes of IKZF1 was significantly higher than that of those with non-functional subtypes of IKZF1 (P<0.01). There was no significant difference in the predicted 5-year RFS rate between the children with functional subtypes of IKZF1 and those with non-functional subtypes of IKZF1 in the SR group (P>0.05). However, the predicted 5-year RFS rate of the children with functional subtypes of IKZF1 was significantly higher than that of those with non-functional subtypes of IKZF1 in the IR group and the HR group (P<0.05).

CONCLUSIONSB-ALL children with non-functional subtypes of IKZF1 have a high recurrence rate, and the recurrence rate will be even higher in B-ALL children with non-functional subtypes of IKZF1 and MRD ≥10 on day 33 of chemotherapy.
