OBJECTIVETo compare the difference among the combined method of oral administration of forlaxand acupoint embedding therapy, the simple acupoint embedding therapy and the simple oral administration of for-lax in the clinical efficacy on diabetic constipation.

METHODSOne hundred and fifty patients were randomized intoa comprehensive group, an acupoint embedding group and a forlax group, 50 cases in each one. In the acupointembedding group, the embedding therapy was applied to bilateral Tianshu (ST 25), Daheng (SP 15), Shangjuxu(ST 37) and Dachangshu (BL 25), once a week. In the forlax group, forlax (polyethylene glycol) was prescribedfor oral administration, once a day, 10 g each time. In the comprehensive group, the acupoint embedding therapyand forlax were combined and the methods were the same as the first two groups. The treatment for 4 weeks wasas one session, and 2 sessions were required in the three groups. Separately, in 4 weeks, 8 weeks of treatment and2 months after treatment, the constipation symptom scores were compared among the three groups. At the end of2 sessions of treatment, the clinical efficacy and adverse reactions were compared among the three groups. In2 months after treatment, the recurrence rate was compared among the three groups.

RESULTSThe total effectiverate was 98. 0% (49/50) in the comprehensive group, better than 86. 0% (43/50) in the acupoint embeddinggroup and 78. 0% (11/50) in the forlax group (both P<0. 01). In the 4 weeks and 8 weeks of treatment, the con-stipation symptom scores were reduced significantly as compared with those before treatment in the three groups(all P<0. 05). The results in the comprehensive group were lower than those in the other two groups (all P<0. 05). In the 4 weeks of treatment, the scores were not different significantly between the acupoint embedding group and the forlax group (P>0.05). In 8 weeks of treatment and 2 months after treatment, the scores in the acupoint embedding group were better tan those in the forlax group (all p<0.05). There were 2 cases of drug adverse reaction in the comprehensive group, 6 cases in the forlax group and 0 case in the acupoint embedding group. The recurrence rate was 8.1% (4/49) in the comprehensive group, lower than 32.6% (14/43) in the acupoint embedding group and 59.0% (23/39) in the forlax group (both P<0.01).

CONCLUSIONthe combined therapy of acupoint embedding and forlax achieves the better clinical efficacy on diabetic constipation and constipation symptom scores as compared with the simple acupoint embedding therapy and the oral administration of forlax the short-term efficacy of the simple acupoint embedding therapy is not different significantly from the simple forlax medication, but the long-term efficacy and safety are better than those of simple forlax medicaiton.

Objective To explore the diameter change of the extrahepatic bile duct before and after laparoscopic cholecystectomy (LC). Methods From Jan. 2006 to Dec. 2007, 113 patients including chronic gallstone cholecystitis (n=55), inactive cholecystolithiasis (n=46) and gallbladder polyps (n=12) were collected and treated by LC. The diameters of their extrahepatic bile ducts were measured by B ultrasonography before operation, 3 months and 6 months after operation. These data were collected and analyzed retrospectively. Results The diameters of the extrahepatic bile ducts of all patients before LC, 3 months and 6 months after LC were (5?2) mm, (8?2) mm and (6?2) mm respectively. And in chronic gallstone cholecystitis patients they were (5?2) mm, (9?2) mm and (6?2) mm respectively, in inactive gallstone cholelithiasis patients they were (5?2) mm, (8?2) mm and (6?2) mm respectively, and in gallbladder polyps ones they were (5?2) mm, (7?2) mm and (5?2) mm respectively. Conclusion The change of the extrahepatic bile duct diameter after LC is a dynamic process. It is enlarged on the third month after operation than before operation. In the sixth month after operation marked retraction occurs, and compared with before operation, it shows no obvious statistic significance.

Hepatitis B virus ( HBV) threatens human's health seriously, immune disorder is the main pathogenesis.HBV cannot naturally infect mouse liver, thus the researchers tried to established HBV mouse models to imitate the immunological pathogenesis of HBV infection.This review summarize various methods to establish HBV mouse models, including HBV transgenic technics, HBV in vivo liver-target transfection technics and HBV naturally infected humanized mouse technics etc.Their advantages, disadvantages and contributions to immunological studies were also analyzed, and the development of this area was also prospected.

Objective To investigate the clinical symptoms and imaging features of Budd-Chiari syndrome with hepatic vein obstruction (HVBCS) and the reasons of mistreatment. Methods Thirteen patients with HVBCS were misdiagnosed and mistreated as inferior vena cava (IVC) obstruction,including 8 patients treated with stent implantation in IVC once and 5 patients with balloon dilatation. After analysis of the clinical symptoms,signs and imaging features; hepatic vein obstruction was further confirmed by digital subtraction angiography (DSA)in all patients. Results All patients had variable degrees of portal hypertension and no apparent symptoms of IVC obstruction. CT or / and MRI showed obvious caudate lobe enlargement and DSA showed IVC narrowing with external compression. All patients were undertaken hepatic vein angiography including 4 with PTV and 9 with hepatic vein stent implantation. All patients' clinical symptoms and signs completely disappeared or markedly improved after the procedure. Conclusion The stenosis of IVC in HVBCS,caused by compression compensatory hypertrophy of hepatic caudate lobe can be cured by hepatic vein angioplasty which is the most correct and effective method.

OBJECTIVE: To observe the short and long-term efficacy of quick repositioning maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in different age groups. METHOD: The clinical data of 113 adult patients with single PC-BPPV who underwent quick repositioning maneuver from July 2009 to February 2015 were retrospectively analyzed. The quick repositioning maneuver was to roll the patient from involved side to healthy side in the coronal plane for 180° as quickly as possible. The patients were divided into 3 groups according to different ages: young group (< 45 years), middle-age group (45 ≤ age < 60 years) and old group (≥ 60 years). The short and long term outcomes of the three groups were observed. RESULT: The left ear was involved in 58 cases (51.3%) and the right ear in 55 cases (48.7%). The short term improvement rates of the young, middle-age and the old groups were 92.5%, 93.6% and 92.3% respectively, and the long term improvement rate was 90.0%, 85.1% and 73.1% respectively. There was no significant difference among the three groups in short and long term outcomes (P > 0.05). The recurrence rate of the three groups was 5.0%, 6.4% and 15.4% respectively, also no significant difference (P > 0.05). CONCLUSION The quick repositioning maneuver along the coronal plane for PC-BPPV has a definite effect for every age groups. The method is simple, rapid and easy to master, and the patients are tolerated the maneuver well without evident side effect.

Objective: To describe the distribution of plasma vitamin B12 concentration in Chinese adults aged 35 to 64 years.Methods:Cross-sectional analysis was empolyed.Plasma vitamin B12 concentration was measured in 2 459 adults sampled from the representative urban and rural areas in the South and North of China.Results:Adjusted plasma vitamin B12 concentration was significantly higher (260 pmol/L) in the Southerners than in the Northerners (189 pmol/L).There were different patterns of seasonal changes of plasma vitamin B12 concentration between South and North.Plasma vitamin B12 concenration was higher during the summer and autumn (269 pmol/L)than during the winter and spring (252 pmol/L) in the South.However,the concentration was lower during the summer and autumn (177 pmol/L) than during the winter and spring (200 pmol/L) in the North.Women tended to have higher plasma vitamin B12 concentration than men.There were 5.5 percent of the participants whose plasma vitamin B12 concentration was lower than 110 mol/L.Conclusion:Significant regional and gender differences in plasma vitamin B12 concentration were observed in Chinese adults.The seasonal changes between the South and North were different.

Objective: To describe the differences of plasma folate concentration and prevalence of folate deficiency in genders and ages in Chinese adults aged 35 to 64 years. Methods: By cross-sectional analysis, plasma folate concentration was measured in 2 545 adults including men and women by microbiological assay. Results: (1) Men tended to have lower plasma folate concentration and higher prevalence of folate deficiency(9.70 nmol/L, 31.0%) than did women(14.2 nmol/L, 12.5%, P=0.001). (2) Men in South have significantly higher plasma folate concentration and lower prevalence of folate deficiency than in North. The difference of plasma folate concentration was not evident between urban and rural area, but evident in North between in winter and spring. There were no significant differences of prevalence of folate deficiency for men between urban and rural areas in both regions. For women, the differences of plasma folate concentration in areas were significant, which were higher in South and urban, and lower in North and rural areas. (3) Plasma folate concentration increased with age in Southern men. A similar trend for others was not significant. Conclusion: Men have lower plasma folate concentration and higher prevalence of plasma folate deficiency than do women. The distribution of plasma folate concentrations in urban and rural areas seems different between men and women.

Objective To discuss the feasibility of laparoscopic renal surgery following kidney rupture.Methods Two patients with left kidney rupture were treated laparoscopiclly at our institution in the last 4 years. 1 operated 7 days after hemorrhage and another operated immediately. Both of them performed retroperitoneal laparoscopic nephrectomy. Results The operations succeeded, the operating time being 100～120 min, the blood loss 200～300 mL. There were no postoperative complications in all cases. Conclusion Laparuscopic exploration and extirpation offer a viable measure to treat kidney rupture.

Objectiye To improve the diagnosis and treatment of chromophobe renal cell carcinoma(CRCC). Methods The clinical dota of 25 patients of CRCC were reviewed.Thirteen were xmales and 12 were females and thirteen on the left and twelve on the right.The mean age was 51 years.Sixteen(64%)patients were asymptomatic.Gross hematuria,low back pain and discomfort and fever occurred in the other 9 patients.Laboratory investigations showed 1 patient had raised alanine aminotransferase and 1 had high erythrocyte sedimentation rate. Results B-ultrasound was mainly characterized by low echo renal mass with intact capsule and low blood flow signals.CT and MR of CRCC were typically well circumscribed,homogeneous(unenhanced CT was 70%,MR was 73%)with no necrosis and hemorrhage,homogenous enhancement(CT was 65%,MR was 67%)and mild enhanced(CT was 65%,MR was 67 %)renal mass.Twenty-two patients with tumors＞4.0 cm had radical nephrectomy and three with tumors≤4.0 cm had partial nephrectomy.The average diameter of tumors was 7.6 cm.The cross-sections of the tumors were grossly homogeneous,pale or dark brown solid.Light microscopy showed that the tumors were composed of trabeculae or sheets with voluminous cells in pale or eosinophilic cytoplasm.Immunohistochemical assay was positive of CK8 and negative of Vimentin.The pathologic TNM stages were 8 with T1a,9 with T1b,6 with T2 and 2 with T3a.Twenty-three patients were followed up.After mean follow-up of 28 months,22 cases were tumor free.One patient had pulmonary metastasis 58 months after operation and had no reaction to interferon-α and chemotherapy and died. Conclusions The majority of CRCC patients are asymptomatic and usually with low-stages.There are some features in CT and MR appearance of CRCC such as well circumscribed and homogenous.Surgical treatment should follow the treatment principles of renal cell carcinoma and carries an excellent prognosis for most localized tumors but there has been no effective measures to treat metastasis disease.The interval between operation and metastasis is relatively long and the time of follow-up should be prolonged in CRCC.
