Objective To explore the clinical effects of treating chronic pharyngitis with point application of Chinese medicinal bread.. Methods Retrospective analysis was adopted in the study. All patients were divided into a point application group (212 cases)and a dissolved medicine group (174 cases). The point application group was treated with point application of Chinese medicinal bread on Tiantu point for successive 4 therapeutic courses (one therapeutic course constitutes 10 days), while the dissolved medicine group was taken pharyngitis dissolved medicines orally for successive 6 therapeutic courses (one course constitutes 6 days). Results The total therapeutic effect of the point application group and the dissolved medicine group was 99.06% and 93.68% respectively. The difference between the two groups has statistical significance. Conclusion Point application of Chinese medicinal bread on Tiantu point is effective in treating chronic pharyngitis.

BACKGROUND:Previous study has observed that the calf acellular dermal membrane exhibits slow repair efficiency, fast degradability speed and other shortcomings in the repair of cartilage defects. OBJECTIVE:To investigate the repair effect of the col agen type Ⅱ-modified acel ular dermal membrane on cartilage defects in rabbits. METHODS:The fetal rabbit chondrocytes were seeded onto the col agen type Ⅱ-modified acel ular dermal membrane, and the composite was then observed under scanning electron microscope at 3, 7 and 14 days. Cartilage defect models were established on the bilateral femoral condyles of 24 New Zealand white rabbits, and these model rabbits were randomly allocated to three groups. The cartilage-acellular dermal membrane and cartilage-collagen type Ⅱ-modified acellular dermal membrane were implanted into the defect regions of control and experimental groups, respectively. Those received no intervention were as blank control group. Collagen type Ⅱ immunohistochemical staining and Wakitani scoring system were performed at 6 and 12 weeks postoperatively. RESULTS AND CONCLUSION:Chondrocytes grew and adhered well in the scaffold. The Wakitani scores in the experimental group were significantly lower than those in the control and blank control groups at postoperative 6 and 12 weeks (P<0.05). At 6 and 12 weeks postoperatively, collagen type Ⅱ immunohistochemical staining was the strongest in the experimental group, with yellow and brown particles in the cytoplasm;the control group was positive for collagen type Ⅱ immunohistochemical staining, while the blank control group was negative for the staining. Our findings suggest that the collagen type Ⅱ-modified acellular dermal membrane is beneficial for the repair of cartilage defects.

Objective To explore the effects of early active mobilization on hand function after zone 5 flexor tendon and ulnar nerve repair.Methods Fifty-five patients who had received primary repair in zone 5 of a flexor tendon and the ulnar nerve were randomly divided into an observation group (26 cases, 88 digits) and a control group (27 cases, 91 digits).Both groups were given routine treatment after the operation, and started to do active and passive exercise 4 weeks later.The observation group was additionally forced to do active range of motion exercise training starting 8 days after the operation.Twelve weeks after the operation, the hand function of both groups was assessed using the total active motion (TAM) scoring system of the American Society for Surgery of the Hand, peripheral nerve function evaluation and the disabilities of arm-shoulder-hand (DASH) scale.Results At the end of the treatment, the average TAM score of the observation group was significantly better than that of the control group.The average active movement range of the wrist in palm flexion, dorsal extension, ulnar deviation and in radial deviation were all significantly better than in the control group.Grip strength, overall hand function and DASH score were also significantly better on average.Conclusion Early active mobilization following flexor tendon and ulnar nerve repair can effectively promote the recovery of hand function.

Objective To study the clinical effectiveness of low cut and five dissector thyroidectomy to treat hyperthyroidism.Methods 337 cases of hyperthyroidism were randomly divided into study group(low cut and five dissector technique,223 cases) and control group(traditional technique,114 cases) according to the ratio of two:operating time,bleeding,complications,recur were compared between these two groups.Results The operating time of the study group and control group were(66.33?25.11)min and(121.27?42.35)min(t=12.75,P0.05).The rate of recurrence was marked(P

Background Vitreous amyloidosis is an autosomal dominant hereditary disease,often leads to reduction of visual acuity and affects life quality of patients.Vitrectomy is the main treatment for vitreous amyloidosis,but the analysis of curative efficacy in China is rarely reported.Objective The study was to observe and analyze the efficacy of vitrectomy for vitreous amyloidosis.Methods The clinical data of 11 eyes from 6 patients with vitreous amyloidosis who received vitrectomy from March 2011 to February 2013 in Affiliated Hospital of Guizhou Medical University.The best corrected visual acuity (BCVA),intraocular pressure (IOP),manifestations under the slit lamp microscope,findings of ocular fundus and results of fundus fluorescence angiography (FFA) were observed after surgery.Pathological examination for vitreous samples was carried by Congo red staining.Results Before surgery,the visual acuity was counting fingers for 30 cm in 5 eyes and hand movement for 30 cm in 6 eyes,and the mean IOP was (13.09±2.12)mmHg (1 mmHg=0.133 kPa).Fixed white flocks in vitreous and white membrane on the posterior lens capsule were seen under the slit lamp microscope.The BCVA remained 1.0 in 7 eyes and 0.8 in 4 eyes 1 week,6 months and 2 years after vitrectomy,and the mean IOP was (13.32±2.07),(14.09±2.47),(12.32±1.87)mmHg at 1 week,6 months and 2 years after vitrectomy,respectively.FFA showed a little fluorescein leakage at peripheral retinal vessel in all eyes at 1 week after vitrectomy but the leakage disappeared at 6 months after vitrectomy.The white flocks increased at peripheral retina in 4 eyes at 2 years after vitrectomy,but the BCVA remained the same in the eyes.Pathological examination of vitreous specimens comfirmed the diagnosis of vitreous amyloidosis.Conclusions Vitrectomy is an effective method for the treatment of vitreous amyloidosis,which can effectively improve the visual acuity of patients.Postoperative recurrence of vitreous amyloidosis appear in parts of patients,but the BCVA is unaffected.

ObjectiveTo investigate the changes of hepatitis B sarfaceantigen (HBsAg) titer in hepatitis B e antigen (HBeAg) positive chronic hepatitis B (CHB) patients treated with nucleos(t)ide analogs and pegylated interferon alfa-2a (PEG IFNα-2a) sequential therapy.Methods Among 6 HBeAg positive CHB patients,3 patients were treated with nucleos(t)ide analogs followed by PEG IFNα-2a for 48 weeks,3 patients were treated with nucleos(t)ide analog monotherapy.The serum HBsAg,anti-HBs,HBeAg,anti-HBe andanti-HBcweredetectedusingthetime-resolved immunofluorometric assay and serum hepatitis B virus (HBV) DNA levels were determined by Taqman polymerase chain reaction (PCR) every 12 weeks.Results HBsAg loss were achieved in three patients after 48-week nucleos(t)ide analogs and PEG IFNα-2a sequential therapy.However,the HBsAg titers of another 3 patients varied from 100 IU/mL to 320 IU/mL.ConclusionIn HBeAg positive CHB patients who obtain virologic response accompanied with HBsAg titer decreasing dramatically by nucleos(t) ide analog treatment,PEG IFNα-2a sequential treatment can increase HBsAg clearance rate.

Objective To investigate the relationship between thyroid nodules with calcification and thyroid carcinoma and its significance in the screening of thyroid carcinoma in high risk group.Methods The clinical data of 1771 patient undergoing surgery for thyroid nodules from March, 2006 to March, 2009 in Huashan Hospital, Fudan University were retrospectively analyzed. Results Among 1771 patients, 500 were finally identified as having malignant tumors. Incidence of calcification in thyroid carcinoma was 68. 4%, and that in benign thyroid nodules was 27.0% ( χ2 = 259. 5, P ＜ 0. 05 ). The specificity of microcalcification for the diagnosis of carcinoma was 89. 4%, and its positive predictive value was 66. 3% ( χ2 = 368.6, P ＜ 0. 01 ). The incidence of thyroid carcinoma in patients ＜ 45 years was 39.2%, while that in patients ≥ 45 years was 22.9% ( χ2 = 51.12, P ＜ 0. 05 ). The incidence of carcinoma in patients of single thyroid nodule was 31.7% and that in those with multiple nodules was 26. 4% (χ2 =4. 766,P ＜ 0. 05). Metastasis was pathologically diagnosed in 26. 8% of lymph nodes found by preoperative ultrasonography. Conclusions The specificity of thyroid nodule calcification, especially microcalcification is high for the diagnosis of thyroid carcinoma. High-risk index for carcinoma includes thyroid nodules with microcalcification, ＜ 45 years old and single thyroid nodule.

69 crabs were collected from Daxing, Gekui and Niukong townships of Lvchun county, Yunnan Province in 2006 and excysted metacercariae were only obtained from crabs of Niukong. The infection rate was 27.6% (8/29) with an average metacercaria number of 2.25 each crab. No encysted metacercariae were found. The excysted metacercariae were morphologically identified as Paragonimus proliferus.
