A canine distemper virus strain was isolated from the lung of dog coming from Aksu in Xing Jiang using lung primary M cell during the CDV molecular epidemiological study. It was demonstrated to be a virulent strain of CDV by a series of systematic identification such as morphology , serology neutralization test, canine infection test, and molecular virology test.

OBJECTIVETo identify the mutations of iduronate-2-sulfatase (IDS) gene, to reveal its mutation features, and to establish a basis for genetic counseling and prenatal gene diagnosis of Hunter syndrome.

METHODSUrine glycosaminoglycans (GAGs) assay, PCR and DNA sequencing were performed to detect mutation of IDS gene of the patient and his parents.

RESULTSThe result showed that the patient was: DS(++), HS(++), KS(-), CS(-), and that both of his parents were negative. A frame-shift deletion mutation (1062 del 16) was identified in exon 7 of the patient's IDS gene. His parents' genotypes were normal.

CONCLUSIONThe patient's mutation was not inherited by his parents but a novel one. The mutation probably altered the primary structure and tertiary structure of IDS enzyme protein remarkably and lowered the activity of IDS enzyme greatly. Therefore it is supposed to be the direct cause of the disorder.

OBJECTIVETo investigate the long-term effects of non-surgical treatment on clinical and hematologic states of patients with generalized aggressive periodontitis (GAgP).

METHODSPatients with GAgP (n = 25) and healthy controls (n = 28) were recruited. The clinical parameters, including probing depth (PD), bleeding index (BI), attachment loss (AL) were examined and recorded. Blood cell variables, including white blood cells (WBC), leukocyte, neutrophil, and lymphocyte counts, as well as serum triglycerides, fasting glucose and protein parameters, including total protein, albumin, globulin, and albumin/globulin ratio (A/G), were analyzed. Twenty-five GAgP patients received non-surgical treatment and the clinical and blood parameters 3 to 7 years after treatment were re-evaluated. Clinical and hematological parameters of the two groups were compared. Comparisons of clinical and hematologic parameters pre- and post-treatment in GAgP group were performed through one-way ANOVA and paired-t test.

RESULTSElevated white blood cells, neutrophil numbers and serum total protein, globulin levels were observed in patients with GAgP compared to controls[(6.3 ± 2.0)×10(9)cell/L vs.(5.4 ± 1.0)×10(9)cell/L, (4.1 ± 1.8)×10(9) cell/L vs.(3.0 ± 0.9)×10(9) cell/L, (78.2 ± 4.4) g/L vs. (75.6 ± 4.6) g/L and (29.3 ± 3.8) g/L vs.(26.5 ± 3.9) g/L respectively, P < 0.05]. A/G ratio was lower in the GAgP group than in the control group (1.7 ± 0.2 vs.1.9 ± 0.3, P < 0.01). Three to seven years after periodontal treatment, the reduction of PD and BI was observed in GAgP group(P < 0.05). There were significant decreases of WBC count, neutrophil count, serum total protein and globulin level, and significant increases of albumin level and A/G at 3 to 7 years after treatment(P < 0.05).

CONCLUSIONSNon-surgical treatment may have long-term beneficial effect on the periodontal clinical status and hematologic parameters of generalized aggressive periodontitis.

Objective To investigate the level of cadmium(Cd)in commercial aquatic products in Xiacheng District, Hangzhou. Methods We randomly collected 293 aquatic products which belonged to six aquatic animals in the markets in Xiacheng District to determine the content of Cd. It was further evaluated by single factor pollution index(PI)according to the standard GB 2762-2017. In 11 samples of swimming crabs, Cd was examined in the different parts. Results There was no significant difference in the content of Cd between the samples collected in the markets and those in the supermarkets. It significantly differed in the samples of different aquatic animals(P < 0.05). The prevalence of Cd that exceeded the standard was as follows: seawater crustaceans(28.6%) > cephalopods(11.1%) > freshwater crustaceans(8.4%) > bivalves(6.9%). However, it was not excessive in the samples of fish. The mean level of Cd in the seawater crustaceans was 0.466 3 mg/kg, which resulted in the proportion of the samples that were excessive being 28.6%. Particularly, the mean level in sea crab was as high as 1.101 mg/kg with the proportion being 66.7%. In the samples of swimming crabs, there was a significant difference in the prevalence of Cd between swimming crab gonads and crab chests or legs(P > 0.05), while no statistical difference between crab chests and legs(P > 0.05). Conclusion The content of Cd in the aquatic products may be excessive in Xiacheng District, which warrants additional regulatory efforts to food safety. The public should reduce the consumption of aquatic products with high content of Cd.

OBJECTIVE: To study the clinical efficacy and complications of Endobutton titanium plate and clavicle hook plate in the treatment of acromioclavicular dislocation. METHODS: Total 48 patients with Rockwood Ⅲ to Ⅴ acromioclavicular joint dislocation from March 2015 to May 2019 were retrospectively divided into two groups according to different surgical methods. Among the patients, 23 patients were treated with Endobutton loop titanium plate fixation (observation group), including 15 males and 8 females, ranging in age from 23 to 59 years old, with an average of(36.2±8.1) years old;Rockwood type Ⅲ in 6 cases, type Ⅳ in 11 cases and type Ⅴ in 6 cases. Twenty-five patients were treated with clavicular hook plate(control group), including 17 males and 8 females, ranging in age from 22 to 54 years old, with an average of (34.7±6.4) years old; Rockwood type Ⅲ in 6 cases, type Ⅳ in 14 cases and type Ⅴ in 5 cases. The operation time, intraoperative bleeding, hospitalization time, visual analogue scale (VAS) of pain, Constant-Murley score of shoulder function and postoperative complications were compared between the two groups. RESULTS: All the patients were followed up, and the duration ranged from 24 to 51 months, with a mean of (30.5±6.5) months. The amountof bleeding and hospitalization time in the observation group were (71.9±4.0) ml and(8.2±1.6) d respectively;and those in the control group were (97.6±13.4) ml and (12.8±1.2) d respectively. There was significant difference between the two groups ( CONCLUSION Compared with clavicular hook plate internal fixation in the treatment of acromioclavicular joint dislocation, Endobutton loop titanium plate internal fixation technology has the advantages of less surgical bleeding, shorter hospitalization time, less postoperative pain, good recovery of shoulder joint function and less complications.

OBJECTIVETo summarize the characters of Kasabach-Merritt syndrome (KMS) and to evaluate the therapeutic effect of drug therapy combined with surgery.

METHODSFrom 2004 to 2010, 59 cases with KMS, who underwent drug therapy and surgery, were retrospectively studied. The average age of the patients, including 33 male and 26 female (male/female, 1.269/1), was 2.9 months (range, 7 days-2.5 years). 28 cases with maxillofacial lesions were treated with the ligation of external carotid artery and injection of carbonyldiamide and methylprednisolone. 31 cases with lesions at trunks and extremities were treated by excision of lesions. All the patients were followed up for 2.8 years (range, 6.5 months -7.3 years). Therapeutic outcomes were assessed by evaluating platelet counts,size of lesion, function of trunk and limb.

RESULTS58 cases were cured except for one dead case. Emergency operation was given in 4 cases, and selective operation was performed in other cases (55 cases). The thrombocyte count, hemoglobin and blood coagulation function returned to normal within 1-2 weeks. The mental condition, appetite, body weight,sleeping were greatly improved one week after treatment. The size of the lesions decreased gradually after the management of ligation of external carotid artery including 18 cases within 6-12 months and 10 cases within 13-24 months. Long term follow-up studies indicated that there was no recurrent case, and the weight, height, immunity of the patients with good function activities were in keeping with the normal counterparts.

CONCLUSIONSThe drug combined with surgery therapy is a very reliable management with high curative rate, short disease period and minimum side-effect.
