Objective To explore the scanning techniques of piriformis and different ultrasonographic characteristics of normal and abnormal piriformis.Methods A total of 40 cases diagnosed with unilateral piriformis syndrome underwent ultrasonic examination.Then ultrasonic scanning techniques of piriformis were summarized.Contours,thickness and smoothness of epimysium and ultrasonic echo of internal muscle texture of piriformis were compared between the normal and abnormal piriformis.The study was approved by the Third Affiliated Hospital Ethics Committee of Zhejiang Chinese Medical University (Approval no.ZSLL-JS-2016-18).Results Interruption of ultrasonic echo of ilium could be considered as ultrasonographic signs for locating piriformis quickly and accurately.Abnormal piriformis in suffering side of patients with piriformis syndrome showed obscure contours and being thicker than the other side [x2 =9.899,P =0.002;(25.81 ± 0.30)mm vs (22.29 ± 0.27)mm,t =13.604,P =0.000].Moreover,there were significant differences in comparing smoothness of epimysium and ultrasonic echo of internal muscle texture of piriformis between the two sides(x2 =23.226,P =0.000;x2 =54.848,P =0.000).Conclusions Interruption of ultrasonic echo of ilium may be an important sign for locating piriformis.Ultrasound can display piriformis clearly and distinguish ultrasonographic images of normal piriformis accurately from abnormal piriformis,which can be taken as an basis imaging for clinical diagnosis of piriformis syndrome.

ObjectiveTo observe the effect of eicosapentaenoic acid (EPA) on the proliferation and apoptosis of human gastric cancer cells and to explore the potential mechanism involved.MethodsHuman gastric cancer cell lines SGC-7901 and MGC-803 were treated with EPA at 10,20,40 μg/ml for 24-72 hours.The inhibition of cell proliferation was evaluated by methyl thiazolyl tetrazolium assay.The apoptosis and the distribution of cell cycle were analyzed by flow cytometry.Mitochondria membrane potential was determined with a fluorescence probe rhodamine 123.Cellular distribution of cytochrome C was quantitatively detected with enzyme-linked immunosorbent assay.Caspase-3 activity was measured with spectrofluorometry.ResultsAfter incubation with 10-40 μg/ml EPAfor 24-72 hours,the proliferation of human gastric cancer cells was markedly inhibited in a time-dependent manner.The treatment of 40 g/ml EPA for 72 hours increased the proportion of G0/G1 phase cells in both SGC-7901 and MGC-803 (P=0.006,P=0.009).In SGC-7901 and MGC-803 cells incubated with 40 μg/ml EPA for 24 hours,mitochondria membrane potential decreased significantly (P =0.001,P =0.047 ); cytochrome C level significantly declined in mitochondria (P=0.001,P=0.000) but increased in cytosol (P =0.001,P=0.000).In SGC-7901 cells,the apoptotic effector caspase-3 activity increased time-dependently along with incubation with 40 g/ml EPA.ConclusionEPA could inhibit the proliferation and promote the apoptosis of human gastric cancer cells through inducing cell cycle arrest and activating intrinsic death pathway mediated by mitochondria.

Objective To evaluate the correlation between the level of CD4+CD25+regulatory T cells in periphend blood and disease severity in patients with sepsis.Methods Thirty-six septic patients and 5healthy controls were enrolled.Septic patients were divided into sepsis group(n=10),severe sepsis group (n=15)and septic shock group(n=11).The lymphocyte was seperated from peripheral blood and marked by PE-CD4 and FTTC-CD25 monoclonal antibody,the level of CD4+CD25+ regulatory T cells was detected by flow cytometry,and the clinical data of APACHE Ⅱ scores of septic patients was considered in 24 hours.The correlation between level of CD4+CD25+ regulatory T cells in peripheral blood and APACHE Ⅱ scores in septic patients was analyzed.Results Compared with the healthy controls [(5.48±0.98)%],the level of CD4+ CD25+ regulatory T cells in sepsis group(10.31±2.32)%,severe sepsis group(14.27 43.33)%,septic shock group(15.32±3.98)% had a significant increase(P＜0.05 or＜0.01).The log value of regulatory T cells in each group correlated positively with the APACHE Ⅱ scores(r=0.829,P=0.032;r=0.868,P=0.021;r=0.913,P=0.009),and the total coefficient of correlation was 0.903(P=0.013).Conclusion The level of CD4+CD25+ regulatory T cells in peripheral blood in septic patients has an abnormal increase,and their levels are related with the severity of disease.

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 evaluate the roles of magnetic resonance imaging and proton magnetic resonance spectroscopy(1H-MRS) in the diagnosis of meningiomas. Methods 98 patients with meningiomas underwent conventional pre-contrast MR and contrast MR. Among them, 28 cases had two dimensional single voxel or multi voxel 1 H-MRS simultaneously both in the lesion's region and the contralateral side. Results On precontrast MR images of 98 cases, T1 WI showed 58.1% (61/105) isointensities, 31.4% (33/105) faintly low intensities and 10. 5% (11/105) mixed intensities; T2WI showed 40. 0% (42/105) isointensities, 41.0%(43/105) hyperintensities, 10.5% (11/105) faintly low intensities and 8.5% (9/105) mixed intensities. After administration of Gd-DTPA, the solid part of the tumors exhibited various enhancement in all the 98 cases.28 cases of MRS exhibited specific different spectral peaks, including increased of choline-containing compounds(Cho), absent or decreased of acetylaspartate(NAA), and the unchanged of creatine(Cr). The value of NAA, Cr, Cho, NAA/Cr, Cho/Cr, NAA/Cho in the tumor center of meningioma were 0. 09 ± 0.06,0.31 ± 0. 22, 0.46 ± 0. 16, 0.33 ± 0. 42, 1.50 ± 0. 68, 0. 15 ± 0.08, compared with the contralateral normal region, Cr has no significant difference (P ＞ 0. 05), NAA, Cho, NAA/Cr, Cho/Cr, NAA/Cho had significantly differences(P ＜ 0.05). Conclusion Conventional pre-contrast MR and contrast MR is the most important dignostic means for meningiomas, 1H-MRS combined with MRI can improve the diagnostic accuracy of meningiomas.

OBJECTIVE: Aimed to analyse the clinical features of the patients with sphenoid sinus mucocele, achieve earlier diagnosis and more timely intervention and decrease the occurrence of misdiagnoses. METHOD: A retrospective study was first conducted in patients with sphenoid sinus mucoele treated in Xiangya hospital from Jan 2000 to Jan 2015. Then literature reports on this disease were collected and analyzed from China National Knowledge Infrastructure (CNKI) and Wan Fang database. RESULT: We collected 82 patients with sphenoid sinus mucocele treated in Xiangya hospital. There were 52 patients presented with headache, 31 patients presented with visual impairment, 10 patients presented with cranial nerve palsy, 2 patients presented with exophthalmos, 15 patients presented with nasal symptoms, and 5 patients with no obvious symptoms. There was no significant difference for symptoms distribution between male and female patients (P > 0.05). Among 45 patients with headache as first symptom and 10 patients with ethmoid sinus mucocele, there were 18 patients and 8 patients subsequently suffering from visual impairment, respectively. We also collected 161 patients in literature except for enrolling, the 82 patients treated in Xiangya hospital, and found that headache was the most common symptom, followed by visual impairment, in the two independent cohorts. CONCLUSION To the best of our knowledge, this is the study of maximum sample for sphenoid sinus mucocele in China. Headache and visual impairment are the most common symptoms for sphenoid sinus mucocele. Surgical treatment should be early performed when the desease accompanied with headache or ethmoid sinus mucocele, to avoid other complications such as visual impairment and even blindness.

OBJECTIVE: To summarize and analyze the clinical characteristics of Mondini dysplasia with cerebrospinal fluid leakage, as well as preliminarily investigate the genetic mechanism of the disease. METHOD: The clinical data of 2 patients diagnosed as Mondini dysplasia with cerebrospinal fluid leakage treated in our hospital were analyzed. Blood samples of these two patients were obtained to extract DNA. We screened DNA samples for gene SLC26A4 mutations by using polymerase chain reaction and direct sequencing. The sequencing results were analyzed in DNASTAR software. RESULT: Both patients came to our hospital because of recurrent meningitis, and the fistula were both located in vestibular window. Patients were cured one-time after surgical closure of the leakages with temporalis + temporalis fascia + temporalis through the mastoid approach. No pathogenic mutations of gene SLC26A4 with exome sequencing were found. CONCLUSION Mondini dysplasia with cerebrospinal fluid leakage should be considered in patients with recurrent meningitis and hearing disorder. Temporal bone HRCT is helpful to the diagnosis. Surgical closure is an effective therapeutic method and may prevent recurrent meningitis. The molecular mechanism of simple Mondini dysplasia needs further study.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.
