Objective To explore the rehabilitation effect of pelvic floor muscle training combined with traditional Chinese medicine in the treatment of mild-moderate pelvic organ prolapse.Methods A prospective ease-control study,choosing 103 patients of mild-moderate pelvic organ prolapse from October 2012 to May 2014 in Maternal and Child Health Hospital Outpatient of Hunan Province,which were randomly divided into study group (52 cases) and control group (51 cases).All of the patients underwent two courses of pelvic floor muscle training,including Kegel exercise,biofeedback,electrical stimulation therapy,the study group combined with traditional Chinese medicine (Buzhongyiqitang) at the same time.The efficacy was analyzed before and after treatment of pelvic floor muscle strength,myoelectric potential and indexing of pelvic organ prolapse quantification (POP-Q) changes.Results There werent statistically significant differences in type Ⅰ and Ⅲ muscle fiber muscle strength and myoelectric potential of two groups before treatment,while the shrinkage index improved significantly after treatment,and the study group was significantly higher with statistically significant difference (P ＜ 0.05).The effective rates of POP-Q indexing changes in two groups were 71.2％ and 56.9％,respectively.The effective rate of the study group was significantly higher than the control group(P ＜ 0.05).Conclusions The clinical efficacy of pelvic floor muscle training combined with Buzhongyiqitang in the treatment of mild-moderate pelvic organ prolapse was significant,and it had a good clinical value.

In order to demonstrate PTB bind to HPRE,reverse transcription,PCR-mediated detection,were used.HepG2.2.15 cell line and HBs-HPRE transient expression cells were adopted to identify PTB function in HBV life cycle.The results showed that PTB could directly bind to HPRE RNA.Functional analysis indicated that PTB could inhibit the expression of HBs antigen and this inhibition was in a dose-dependent manner in HepG2.2.15 cells.Higher expression of HBs in cells transfected pcDNA3-HBs-HPRE comparing with pcDNA3-HBs,and this high expression could also be inhibited by PTB.The data demonstrated that PTB inhibits HBs expression by interacting with HPRE.

OBJECTIVETo discuss a new technique about reconstruction of medial collateral ligament (MCL) with double bundle allograft and to evaluate the short-term clinical efficacy.

METHODSAll 53 patients who suffered from valgus instability of the knee were selected. All cases were diagnosed of MCL injury because the medial gap of the knee widened more than 5 mm compared with collateral knee by the stress X-ray, MRI displayed discontinuity of MCL and valgus stress test was positive. All patients were accepted arthroscopic evaluation through inferomedial and inferolateral arthroscopy portal incisions to ascertain whether there were intra-articular injuries. An 8 cm incision was made from 1 cm superior adductor tubercle to 5 cm proximal medial tibia joint line in a longitudinal fashion. The anterior tibia insertion was defined as 15 mm lateral from the medial tibia edge and 45 mm under the medial tibia joint line. The posterior tibia insertion was defined as 15 mm lateral from the medial tibia edge and 20 mm under the medial tibia joint line. We used 5 mm or 6 mm reamer to drill the tibia tunnel along with guide pin, and then drill the femur tunnel with 6 mm or 7 mm drill in the top of the adductor tubercle about 25 mm or 30 mm length. The allograft was pulled into the tunnel from tibia to the femur and fixed with absorbable interference screw. Patients carried out active rehabilitation program after operation. One year after the operation, IKDC score, Lysholm score were used to evaluate the clinical effect.

RESULTSThe IKDC score (A or B, 86.78% vs. 0), Lysholm scores (89.7 ± 3.4 vs. 51.8 ± 4.9, t = -79.724, P < 0.05) were significantly improved compared with preoperative in all patients. Medial joint widened gap decreased from (10.4 ± 2.4) mm preoperative to (2.8 ± 1.5) mm postoperative from X ray and the differences were significant (t = 41.727, P < 0.05). Among these patients, the medial joint widened gap of 46 cases were less than 3 mm, 7 cases were from 3 mm to 5 mm. The range of motion was 135.4° ± 2.5° preoperative and 132.7° ± 3.7° postoperative. The 9 patients still had medial tenderness 1 year after operation.

CONCLUSIONApplication double bundle allograft technique to reconstruct MCL can significantly improve the stability of the knee and the short-term clinical efficacy was sure.

OBJECTIVETo investigate the therapeutic effect of digital dorsal flap based on vascular network for skin defects at fingers.

METHODSFrom August 2005 to August 2010, 49 cases with 61 skin defects at fingers were treated with the digital dorsal flaps, including 19 at the index fingers, 19 at the middle fingers, 16 at the ring fingers and 3 at the little fingers. The defects were 42 at the distal end, 12 at the middle segment and 7 at the proximal segment. The flaps size ranged from 27 mm x 20 mm to 10 mm x 8 mm.

RESULTS61 flaps in 49 cases survived completely. 52 fingers were followed up for 6-22 months. The aesthetic and functional results were both satisfactory. The flaps sensation was graded as S3, with a discrimination distance of 6-9 mm (median, 7.6 mm). No complication happened in donor sites.

CONCLUSIONSThe digital dorsal flap based on vascular network has reliable blood supply with less morbidity to the main artery. It is safe and easily performed with good effect for skin defect at finger.

OBJECTIVETo assess the value of histologic examination, immunohistochemistry and gene rearrangement studies in the diagnosis and subtyping of lymphoma with bone marrow involvement (BMI).

METHODSSixty-two formalin fixed, paraffin embedded bone marrow biopsy specimens were studied. Immunohistochemical and immunoglobulin heavy chain (IgH) and T-cell receptor gene rearrangement studies were performed in each case.

RESULTSChronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) demonstrated mainly and interstitial infiltration by dysplastic lymphocytes, with intertrabecular nodular arrangement or in dispersion. Sometimes, pseudofollicles may be noted. A predominantly para- or intertrabecular infiltration by nodules of lymphoma cells was characteristic of follicle center cell lymphoma (FCL) cases. In most lymphoplasmacytoid lymphoma (LPL) cases, there was infiltration by small lymphocytes and plasma cells between bony trabeculae. In marginal zone cell lymphoma (MZL), vague inter- or para-trabecular nodules of polymorphic lymphoma cells with clear cytoplasm might be noted. Small to medium-sized dysplastic lymphocytes, with absence of paraimmunoblasts or pseudofollicles, were the most frequent findings in mantle cell lymphoma (MCL). Hairy cell leukemia (HCL) might be identified by the presence of distinct cell membrane and abundant clear cytoplasm, resulting in a "fried-egg" appearance. Tumor cells with large nuclei and eosinophilic nucleoli were characteristically seen in lymphomatosis diffusa (Hodgkin's disease, HD). In T-cell non-Hodgkin lymphoma with BMI, dispersed or clusters of intertrabecular neoplastic lymphoid cells with clear cytoplasm and gyriform nuclei were often observed. In diffuse large B-cell lymphoma (DLBL), the tumor cells were large and isolated or arranged in diffuse pattern. Immunohistochemically, a panel of markers, including CD3 CD20, and CD79 are valuable for the differential diagnosis of T- and B-cell lymphomas. The neoplastic cells in MCL were cyclin D1- and CD5-positive, while BCL2- and CD10-positivity was characteristic for FCL. CLL/SLL cells might be stained with CD5 and CD23, in addition to CD20 and CD79. CD25 expression might be noted in HCL: the positivity for CD15, CD30 and fascin suggests HD. There was a higher positivity rate for IgH gene rearrangement in CLL/SLL, LPL MZL and DLBL (80%, 60%, 66.7%, 70% respectively) and for T- cell receptor gamma gene rearrangement in T-cell lymphoma (66.7%).

CONCLUSIONA combination of histopathology, immunohistochemistry and IgH / T-cell receptor gamma gene rearrangement studies may be of aid to the diagnosis and subtyping of lymphoma with BMI, especially if there is only a small number of tumor cells present in the specimen.

BACKGROUNDThe prevalence of malocclusion in modern population is higher than that in the excavated samples from the ancient times. Presently, the prevalence of juvenile malocclusion in the early stage of permanent teeth is as high as 72.92% in China. This study aimed to observe and evaluate the prevalence and severity of malocclusions in a sample of Xia Dynasty in China, and to compare these findings with the modern Chinese population.

METHODSThe material consisted of 38 male and 18 female protohistoric skulls of Xia Dynasty 4000 years ago. Of 86 dental arches, 29 cases had the jaw relationships. Tooth crowding, diastema, individual tooth malposition and malocclusion were studied.

RESULTSOf the samples, 23.3% showed tooth alignment problems including crowding (8.1%), diastema (9.3%), and individual tooth malposition (5.8%). The prevalence of malocclusion was 27.6%, mainly presented as Angle Class I.

CONCLUSIONSIt is indicated that over thousands of years from Neolithic Age (6000 - 7000 years ago) to Xia Dynasty (4000 years ago), the prevalence of malocclusion did not change significantly. The prevalence of malocclusion of Xia Dynasty samples was much lower than that of modern population.

Objective To understand the pathogenic distribution and epidemiological trend of hand-foot-and-mouth disease (HFMD),and provide evidence for the prevention and control of HFMD.Methods Children who were diagnosed with HFMD in a hospital between January and December 2015 were investigated,real time fluorescence PCR was used to detect enterovirus universal type EV,enterovirus 71 (EV71),and Coxsackievirus A16 (CoxA16) in specimens from children with HFMD.Positive rates and distribution of various types of EV among children of different months,genders,age groups,and infection types were analyzed.Results A total of 837 throat swab specimens from HFMD children were collected in 2015,380 (45.40％) of which were EV positive specimens.Virus typing showed that 110 (28.95 ％),7 (1.84 ％),6(1.58 ％),and 257(67.63 ％) were positive specimens for EV71,CoxA16,EV71 + CoxA16,and other types of EV.HFMD had a high prevalence since April,reached a peak in May-June,and remained high incidence in July-December.Positive rates of EV in children of different months were statistically different (P＜0.05).The age of onset was mainly in children under 3 years.Positive rates of EV and constitute ratios of different types of EV in children of different age groups were all statistically different (all P＜0.05).The positive rate of EV in severe HFMD cases was higher than common cases (65.34％ vs 27.06％,P＜0.001).The proportion of severe cases in children with EV71 infection and other types of EV infection were 90.00％ and 60.70％ respectively;children with EV71 + CoxA16 double infection were all severe cases.Constitute of EV types in children with different infection types was statistically different(P＜0.001).Conclusion In 2015,EV infection in hospitalized children with HFMD in this hospital was mainly caused by other types of EV (nonEV71 and non-CoxA16),the high prevalence season,high-risk population under 3 years of age,and severe cases should be paid high attention,prevention and treatment should be performed well.

OBJECTIVETo investigate the status of lymph node metastases (LNM) of esophageal carcinoma and to identify the risk factors.

METHODSClinical data of 308 patients who underwent esophagectomy with three-field lymphadenectomy during January 2006 and December 2010 were reviewed. Characteristics of LNM were studied.

RESULTSThe average number of dissected lymph nodes was 35.6 ± 14.5 in 308 patients. There were 197 patients(64%) had LNM. Logistic regression analysis showed that lymphatic vessel invasion(P=0.019) and deep tumor invasion(P<0.001) were risk factors of LNM. The highest LNM site was paratracheal node(25.0%). The incidence of cervical LNM was 14.1% in the middle thoracic carcinoma, higher than that of upper thoracic (7.3%) and lower thoracic (8.3%). Rate of LNM was lower in upper thoracic carcinomas than that in middle or lower ones(P=0.001). No significant difference of LNM was found among upper, middle and lower thoracic carcinoma for cervical or thoracic nodes. Lymphatic vessel invasion(P<0.001) and metastases in paratracheal lymph nodes (P=0.014) were risk factors for cervical LNM.

CONCLUSIONSLNM of esophageal carcinoma can be found in both directions vertically and skipped metastasis. Paratracheal lymph nodes involvement is an indicator for cervical lymphadenectomy in thoracic esophageal carcinoma.
