OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

OBJECTIVE: To study the morphological characteristics of femurs of adult human and 11 kinds of adult animals from cattle, horses, pigs, goats, sheep, dogs, cats, rabbits, geese, ducks, chickens, and to establish an effective species identification method among various species. METHODS: The 4 cm mid-diaphyseal segment of the femur from adult human (older than 20 years old) at autopsy was obtained. Addi-tionally, the 4 cm ones from 11 kinds of adult animals were obtained. After decalcification, all femurs were made into slices, and then were observed by optical microscope. The 25 indexes were selected and analyzed by step discriminant analysis according to differences between human and mammal, human and poultry, and human and 11 kinds of animals. RESULTS: The histological structure of bone mineral density of middle part of femur had obvious characteristics among the species. And the morphology and number of osteon showed the trend of obvious biological evolution. There were 11 indexes with significant differences between human and 11 kinds of animals to establish some mathematical models to discriminate all species. The correct discrimination rate was 96.3% between human and mammal. The correct discrimination rate was up to 100% between human and poultry, and was 89.4% among human, mammal and poultry. CONCLUSION The mathematical models have good correct discrimination rate among human and the other animals, which could be applied in the practical species identification cases.

OBJECTIVETo analyze retrospectively the postoperative complications of acromioclavicular joint dislocation (Tossy III) and explore the preventative methods for the complications.

METHODSForty-eight cases of acromioclavicular joint dislocation (Tossy III) were reviewed, 14 cases treated with open reduction and Kirschner wire combined with steel wire fixation (group A), 11 cases treated with open reduction and lag screw or steel wires fixation (group B), 23 cases treated with open reduction and AO clavicular hook plate fixation (group C). The acromioclavicular ligament, articular capsule, coracoclavicular ligament and coracoacromial ligament were repaired in all patients. The reasons of postoperative complications were analyzed.

RESULTSForty-eight patients got average follow-up of 18 months. In group A, 8 patients obtained excellent results, 4 good and 2 poor; in group B, 7, 3 and 1, respectively; in group C, 21, 1 and 1, respectively. The excellence rate showed statistical difference between group A and C (P < 0.05). In group A, 4 cases with postoperative pain, 3 cases with periarthritis of shoulder, 3 cases with arthritides of acromioclavicular joint, 4 cases with internal fixation failure and 2 cases with recurrence of joint dislocation; in group B, 3, 2, 1, 3 and 1, respectively; in group C, 22, 2, 1, 2 and 1, respectively. There was no significant difference in postoperative complications in three groups (P > 0.05).

CONCLUSIONSelection of the suitable internal fixation and reconstruction of coracoclavicular and coracoacromia ligaments is the basic operation. Acromioclavicular space debridement, ligamentous reconstruction, rigid internal fixation are effective methods to reduce postoperative complications for the treatment of acromioclavicular joint dislocation.

Objective To evaluate the endoscopic features and treatment of gastrointestinal carciholds. Methods Data of 44 patients diagnosed as gastrointestinal carcinoid from 2002 to 2009, including clinical manifestation, endoscopic findings, treatment and follow-up, were analyzed retrospectively. Results Most common presentations were abdominal pain and changes in bowel habits, while some patients (n = 7 ) did not have any symptoms. Most lesions were elevated submucosal ones with normal mucosal pit pattern of type Ⅰ . Larger lesions appeared as polyps with mucosal pit pattern of type Ⅲ and 1 malignant carcinoid as type Ⅴ. Endoscopic ultrasonography were performed in 29 patients and all lesions were presented as submucosal hypoechoic masses with distinct borders. Endoscopic fulguration with high frequency current was applied in 12 patients and endoscopic mucosal resection (EMR) in 32. One patient with malignant carcinoid accepted multiple EMRs and died from lung and liver metastasis 6 months after last procedure. No recurrence was observed in other 43 patients during the follow-up visit of 3 months to 5 years. Conclusion Gastrointestinal carcinoid is lack of specific symptoms, and the diagnosis is made by endoscopic and pathologic findings.

Objective To study the characteristics of heterotopic pancreas (HP) in upper gastrointestinal tract (UGIT) under endoscopy and endoscopic sonography ( EUS), and its endoscopic managements. Methods Data of 67 patients with pathologically confirmed HP in our hospital from March 2004 to November 2009, including clinical and endoscopic manifestations and sequelae after endoscopic resection,were retrospectively studied. Results Heterotopic pancreas were most commonly found as a single lesion in gastric antrum (62/67, 92. 5% ) and in gastric angle and duodenum as well, which were characterized by protrusion, with intact mucous membrane and centrally umbilicated. Of the 67 patients, 59 underwent EUS before endoscopic resection. Findings were heterogeneous and mixed echogenic lesions with indistinct borders involving both the second and third layers of the gastrointestinal wall, sometimes even involving the first and fourth layers. Most lesions (n =60) were removed by endoscopic mucosal resection (EMR), with basal residues in 25 cases, in which fourth layer involvement was observed in 23 cases (92. 0% ). Delayed bleeding occurred in 1 case at 3rd day after the procedure, and no other complications were observed. Complete removal was achieved in 8 cases ( including one receiving EMR previously ) with endoscopic submucosal dissection (ESD) , and there was no such severe complications as perforation. Postoperative pathological examinations revealed that the consistent rate of preoperative diagnosis with EUS was 91.5% (54/59). Conclusion Endoscopy combined with EUS is critical in diagnosis of HP in UGIT. EMR, especially with cap assistance, is the best method for those without involvement of muscularis propria, while ESD or endoscopic surveillance is a better alternative for those with 4th layer involvement.

OBJECTIVEto investigate if the cartilaginous surface and corresponding osseous contour of the patellofemoral joint match in the axial plane for providing theoretical basis with evaluating alignment of patellofemoral joint and designing the part of patellofemoral joint in knee prosthesis.

METHODSfrom January 2009 to March 2010, 9 human cadaver knees were prepared, which chandra of patellofemoral joint didn't degenerate. Each specimen was sectioned in the axial plane at 20° to 30° knee flax. The cross-sections revealed characteristics in the bony anatomy and corresponding articular surface geometry of the patellofemoral joint in the axial plane. Evaluating parameters included osseous patella congruence angle (OPCA), chondral patella congruence angle (CPCA), patella chondral convex point parameter (PCCPP), patella subchondral osseous convex point parameter (PSOCPP), the parameters of the deepest (chondral or osseous) point of the intercondylar sulcus. After that, the osseous and cartilaginous contours and subchondral osseous contours of the patella in the axial plane were analyzed through MRI data of 11 patients who didn't degenerate in patellofemoral joint cartilage. Parameters as same as cadaver knees were compared.

RESULTSdata from specimens of OPCA was (-4.5 ± 1.1)°, CPCA was (0.5 ± 0.8)°, PCCPP was 1.13 ± 0.11, PSOCPP was 1.67 ± 0.14, PCDPIS was 1.35 ± 0.28, PODPIS was 1.38 ± 0.33. Date from MRI of OPCA was (-3.8 ± 1.4)°, CPCA was (0.7 ± 1.0)°, PCCPP was 1.05 ± 0.21, PSOCPP was 1.73 ± 0.18, PCDPIS was 1.41 ± 0.21, PODPIS was 1.37 ± 0.27. The patella exhibited significant differences in the bony vs. chondral anatomy (P < 0.05), but the intercondylar sulcus nearly match in the bony vs. chondral anatomy.

CONCLUSIONSthe cartilaginous surface and corresponding osseous contour of the patella don't match in the patellofemoral joint axial plane, but that of the trochlea nearly matches. This is very important for accurately evaluating alignment of patellofemoral joint because the normal osseous alignment of patellofemoral joint don't represent the normal alignment and helpful for designing the part of patellofemoral joint in knee prosthesis.

Objective: To investigate the impact of portal hypertention with hypersplenism of different severity and splenectomy on prognosis of hepatocellular carcinoma (HCC). Methods: We retrospectively analyzed the clinical data of 403 patients with HCC who met the Milan criteria and received radical treatment in Tianjin Third Central Hospital from January 2008 to January 2018. Cox propor-tional risk regression analysis was performed for parameters such as platelet levels (PLT), albumin-bilirubin (ALBI) grade, aspartate ami-notransferase-to-platelet ratio index (APRI), and post-sinusoidal resistance (PSR). HCC patients with severe hypersplenism were as-signed into two groups according to treatment method: radical treatment for HCC alone and radical treatment for HCC plus splenecto-my. Clinical data were compared, and the two groups were evaluated using the Kaplan-Meier survival analysis method. Results: Univar-iate and multivariate analyses showed that PLT was an independent risk factor for overall survival (OS) and disease-free survival (DFS) in patients with HCC. OS curves differed significantly with different PLT among patients with HCC (P=0.013). Furthermore, parameters of portal hypertension in cirrhosis, such as PSR, APRI, and ALBI grade, were risk factors for HCC prognosis. The degree of portal hyper-tension and hypersplenism, liver function, and tumor-node-metastasis stage did not differ between the two groups (P>0.05). Survival analysis showed significantly longer OS in the radical treatment plus splenectomy group (P=0.025). Following were the 1-, 3-, and 5-year survival rates: radical treatment alone group 100% , 98.2% , and 68.5% and radical treatment plus splenectomy group. 97.1% , 79.4%, and 56.8%, respectively. DFS did not differ between the two groups (P=0.326). Conclusions: Clinical parameters, such as PLT, PSR, APRI, and ALBI grade, are important prognostic factors in HCC patients with portal hypertension and hypersplenism. Radical treat-ment for HCC plus splenectomy can improve OS in HCC patients within the Milan criteria with severe hypersplenism.
