Objective To explore effect of fetal lymphocyte on pathogenesis of intrahepatic cholestasis of pregnancy(ICP).Methods Twenty pregnant women with ICP and 20 normal pregnant women were enrolled in the study.The single mixed lymphocyte culture/reaction(MLC/MLR)was conducted using inactive lymphocyte obtained from maternal peripheral blood and lymphocyte of cord blood from fetus.Antigen-induced-lymphocyte-proliferation-reaction was used for dermic soluble antigen and decidual soluble antigen obtained from maternal blood and cord blood from fetus.The intense of proliferation was calculated and compared between normal and ICP-complicated pregnancies.Results(1)The level of intense of proliferation of fetal lymphocyte was significantly increased in ICP group 2.75?0.36 than those of normal control group 1.45?0.19 in single mixed lymphocyte culture(P＜0.05).(2)The level of intense of proliferation of fetal lymphocyte was significantly increased in ICP group 1.45?0.19 than those of normal control group 0.67?0.24 in decidual soluble antigen induced lymphocyte proliferation reaction(P＜0.05). (3)The level of intense of proliferation of fetal lymphocyte was significantly increased in ICP group(1.22?0.44)than those of normal control group(0.66?0.27)in dermic soluble antigen induced lymphocyte proliferation reaction.Conclusions(1)The fetal lymphocyte may be one of the effector cells in pathogenesis of ICP.(2)The disturbance of fatal-maternal immune-tolerance is one of the important mechanisms underlying ICP.

OBJECTIVETo explore the fixation methods in treatment of tibial fracture in adolescents by comparing the results and complications of three fixation methods and to determine the factors related to those complications.

METHODSFrom January 2007 to January 2012, 83 diaphyseal tibial fractures in 79 adolescents were treated with elastic stable intramedullary nail fixation, plate fixation, or external fixation respectively. There were 55 males and 24 females with an average age of 13.9 years (ranging from 11 to 17.6 years). Outcomes were compared in terms of the hospital stay,time to union, complications, and reoperation rates.

RESULTSAll patients were followed up for 15.8 months in average. The time to union was significant associated with the pattern of fixation, energy of the injury, multiple and open fracture. The time of bone union of external fixation group was longer than that of elastic stable intramedullary nail fixation and plate fixation groups. But complication rates of external fixation group were higher than that of elastic stable intramedullary nail fixation and plate fixation groups. Four patients were treated with elastic nail fixation underwent a reoperation (loss of reduction in 2 cases, delayed union and nonunion in each 1 case). Six patients were treated with external fixation required a reoperation (loss of reduction in 3 cases, malunion in 2 cases, and replacement of a pin canal infection in 1 case). Two fractures were treated with plate fixation required refixation following nonunion and malunion. A multivariate analysis with adjustment for baseline differences showed external fixation to be associated with a 7.56 times (95% confidence interval=3.74 to 29.87) greater risk of loss of reduction and (or) malunion than elastic stable intramedullary nail fixation. At the final follow-up,there were agreeable results among three groups and no significant differences among them in final therapeutic effect (P>0.05).

CONCLUSIONExternal fixation for treatment of tibial fracture in adolescents has the highest rate of complications than the other two fixation methods. Elastic stable intramedullary nail fixation can achieve the same effect of other fixed system and avoid most of the complications. Operation method choice depends on the experience of doctors and patients' basic situation and the fracture types.

OBJECTIVETo compare the clinical efficacy in the treatment of post-stroke shoulder-hand syndrome between floating-needle therapy and conventional acupuncture on the basis of rehabilitation training.

METHODSOne hundred cases of post-stroke shoulder-hand syndrome were randomized into a floating-needle group and an acupuncture group, 50 cases in each one. The passive and positive rehabilitation training was adopted in the two groups. Additionally, in the floating-needle group, the floating-needle therapy was used. The needle was inserted at the site 5 to 10 cm away from myofasical trigger point (MTrP), manipulated and scattered subcutaneously, for 2 min continuously. In the acupuncture group, the conventional acupuncture was applied at Jianqian (EX-UE), Jianyu (LI 15), Jianliao (TE 14), etc. The treatment was given once every two days, 3 times a week, and 14 days of treatment were required. The shoulder hand syndrome scale (SHSS), the short form McGill pain scale (SF-MPQ) and the modified Fugl-Meyer motor function scale (FMA) were used to evaluate the damage severity, pain and motor function of the upper limbs before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSSHSS score, SF-MPQ score and FMA score were improved significantly after treatment in the two groups (all P < 0.01), and the improvements in the floating-needle group were superior to those in the acupuncture group (all P < 0.05). The total effective rate was 94.0% (47/50) in the floating-needle group, which was better than 90.0% (45/50) in the acupuncture group (P < 0.05).

CONCLUSIONThe floating-needle therapy combined with rehabilitation training achieves a satisfactory efficacy on post-stroke shoulder-hand syndrome, which is better than the combined therapy of conventional acupuncture and rehabilitation training.

OBJECTIVE: To determine the effect of continuously compressive pressure (CCP) on the expression of receptor activator of nuclear factor kappa B ligand (RANKL) in human periodontal ligament cells (HPDLCs) and to investigate the role of RANKL in alveolar bone rebuilding during orthodontic tooth movement. METHODS: The primary HPDLCs were isolated from human periodontal ligament by explanting enzymatic digestion with trypsin and collagenase to establish a pressure model. Top-bottom axial pressures (1, 2, and 3 g/cm(2)) were laid on HPDLCs for 0.5, 1.5, 6, 12, 24, and 48 h, respectively. The RANKL expression was identified by the reverse transcription-polymerase chain reaction (RT-PCR) at the mRNA level. RESULTS: The expression of RANKL mRNA significantly increased in a time-dependent manner (P<0.01), so did the value of pressure, especially in the 2 g/cm(2) group (P<0.05). CONCLUSION CCP can up-regulate the expression of RANKL mRNA in human periodontal ligament cells.

Objective To investigate the flexibility of both the covered stents specially designed for use in intracranial vasculature and the delivering system in passing through the bone tube and the physiological curves of the cranial internal carotid artery(CICA)to reach the targeted area,the performance (adherence)of the covered stents in occluding vascular wall diseases and the impact on the vascular branches of the covered segment.Methods The covered stents specially designed for use in intracranial vaseulature were used to treat 13 patients with CICA diseases using endovascular techniques.There were 4 huge pseudoaneurysms,4 giant aneurysms,3 small wide-necked aneurysms,1 giant pseudoaneurysm with concurrent internal carotid cavernous fistula(CCF),and 1 CCF.Prior to the detachment of the covered stents,balloon occlusion test(BOT)of the internal carotid artery on the diseased side and whole-brain digital subtraction angiography(DSA)were performed in all the patients.Three to 16 months following procedure,DSA and clinical follow-ups were performed.Results Thirteen patients all tolerated the BOT well with the DSA demonstrating well-opened anterior and posterior communicating arteries.The covered stents and the delivering systems all successfully passed CICA to reach the targeted diseased area,with the diseased segments of the internal carotid artery including C3—C4 in 4 cases,C4—C5 in 4 and C6—C7 in 5.Immediately following the detachment of the covered stents,DSA demonstrated that 7 aneurysms were completely occluded,4 aneurysms had slight endoleak,and 1 CCF had markedly-decreased blood flow through the fistula.In the patient with concurrent pseudoaneurysm and CCF,the pseudoaneurysm disappeared and the blood flow through the fistula was markedly-reduced immediately following the stenting procedure.Apart from one patient with aneurysmal subarachnoid hemorrhage who died due to extensive vascular spasm on the 9th day following the stenting procedure,all the other 12 patients had unobstructed stented vessels on the follow-up DSA images,with 2 demonstrating slight stenosis.In the 6 patients with post-procedure endoleak,DSA showed that the endoleak in 4 patients had disappeared,one endoleak disappeared following the second stenting,and one CCF remained low-flow fistula.There was no sequela related to the occlusion of branches in the covered arterial segment.Conclusion The covered stents specially designed for use in the intracranial vasculature and the delivering system are both flexible enough to pass the tortuous CICA to reach the intracranial diseased artery,and are effective in managing CICA diseases.Further follow-up is still needed to determine the long-term effect of the covered stents,and the adherence of the covered stents needs further investigation.

OBJECTIVETo evaluate the clinical value of HER2 overexpression in breast cancer and its prognostic implication in patients with lymph node negative breast carcinoma.

METHODSThe following electronic database were extracted using appropriate inclusive and exclusive standards: Cochrane library, PUBMED, Embase (1984 - 2003), OVID, CMCC and CNKI. Excel and RevMan 4.2 were used for statistical analysis.

RESULTSFifty-six articles were extracted to calculate the positive rate of HER2 overexpression. The pooled positive rate was 23.14% [19.54%, 26.73%], with positive immunohistochemistry (IHC) rate of 23.13% [19.49%, 26.77%] and positive FISH rate of 20.90% [15.54%, 26.25%]. Seven articles were used to evaluate prognostic predication of HER2 expression. It was concluded that in patients with lymph node negative breast carcinoma, HER2 overexpression (both IHC and FISH) independently predicted a poor prognosis based on disease-free survival (DFS) and overall survival (OS) with a P < 0.05. For DFS, the pooled RR was 1.38 [1.07, 1.80] with 1.16 [1.02, 1.31] for IHC and 1.98 [1.56, 2.52] for FISH. For OS, the pooled RR was 1.58 [1.16, 2.14] with 1.37 [1.14 to 1.64] for IHC and 2.33 [1.45 to 3.75] for FISH. HER2 overexpression effectively predicted DFS/OS of patients without adjuvant therapy and OS of patients with the therapy, but not for DFS, with the pooled RR of 1.46 [1.02, 2.09] and 1.11 [0.95, 1.31] for DFS, respectively and the pooled RR of 1.93 [1.44 to 2.58] and 1.25 [1.01, 1.56] for OS, respectively.

CONCLUSIONSIn patients with lymph node negative breast carcinoma, the positive rate of HER2 overexpression is 23.14%. HER2 overexpression indicates a poor prognosis and adjuvant therapy after surgery should be recommended.

OBJECTIVETo study the clinicopathologic features and prognosis of primary lymphoma of breast.

METHODSForty cases of primary breast lymphoma, diagnosed according to the 2008 World Health Organization classification of hematopoietic and lymphoid tumors, were retrospectively studied. Immunohistochemistry was performed by SP method. The follow-up data were analyzed.

RESULTS(1) All the patients were females and the median age was 47 years. Unilateral and bilateral breast involvement were noted in 36 and 4 patients, respectively. The number of tumor were 31 cases (77.5%, 31/40) less than 3, and 9 cases (22.5%, 9/40) were 3 and more than 3. According to Ann Arbor staging system, 33 cases (82.5%) were in stage I to II and 7 cases (17.5%) in stage III to IV. The level of LDH in 9 cases (24.3%, 9/37) went up. For ECOG scores, 34 cases (85.0%) were 0 to 1 score and 6 cases (15.0%) were more than 2 scores. With respect to international prognostic index, 83.8% (31/37) were of score 0 to 2 and 16.2% (6/37) were of score 3 and more than 3. The axillary lymph nodes of 21 patients (53.8%, 21/39) were involved by the malignancy. (2) Histologically, 38 cases (95.0%, 38/40) were classified as B-cell lymphoma [including 27 cases (67.5%) of diffuse large B-cell lymphoma, 8 cases (20.0%) of mucosa-associated lymphoid tissue lymphoma, 2 cases of follicular lymphoma and 1 case of lymphoplasmacytic lymphoma]. The remaining cases included one case of peripheral T-cell lymphoma and one case of lymphoblastic lymphoma. Immunohistochemically, expression of CD20+/- CD79a were demonstrated in the 38 cases (95.0%) of B-cell lymphoma. The staining for CK was negative in all cases. In 33 cases, the positive rates of MUM-1, bcl-6 and bcl-2 were 57.6% (19/33), 30.3% (10/33) and 72.7% (24/33), respectively. Three cases were germinal center B cell phenotype and 21 cases were non-germinal center B cell phenotype. (3) Follow-up information was available in 37 patients (92.5%, 37/40). Twenty-three patients (62.2%, 23/37) were still alive and fourteen ones (37.8%, 14/37) died. For the 27 cases with diffuse large B-cell lymphoma, the five-year and disease-free survival rates were 48.0% and 36.0%, respectively.

CONCLUSIONSPrimary breast lymphoma is a rare disease entity. Diffuse large B-cell lymphoma is the commonest histologic type and the majority show a non-germinal center B cell phenotype. The level of LDH, number of tumor and international prognostic index are of prognostic significance.
