OBJECTIVE:
By analysing the video-nystagmography findings of positional tests,to evaluate the therapeutic effect of the patients with horikontal semicircular canal cupulolithiasis (HSC-Cup).
METHOD:
A retrospective study of 36 patients with HSC-Cup. The induced nystagmus in roll tests was recorded by videonystagmography, whose direction, latency, intensity and time characteristics were analysed. All of the 36 patients were treated with lying position avoiding normal side and oral-taken betahistine mesilate tablets. A week later return visits and curative effects evaluation were made.
RESULT:
Horizontal apogeotropic nystagmus was induced by turning left or right in HSC-Cup roll tests. The time of latency and duration turning to normal and lesion side were(0. 93 ± 0. 65)s and(1. 01 ± 0. 78)s, (100.58 ± 36. 56)s and (118. 65 ± 143. 71)s, which showed no statistically significant difference (P>0. 05). The duration of nystagmus was more than 60 seconds. The intensity of nystagmus turning to normal and lesion side were(45.58 ± 28.71)°/s and (20.42 ± 16. 64)°/s. The intensity turning to normal side was greater than lesion side obviously. The difference was statistically significant (P<0. 05). Twenty-three patients withright HSC-Cup, and 13 patients with left HSC-Cup were taken in count. They were treated with above methods and return visit a week later. Twenty-eight patients (77. 77%) were cured, 36 patients (100. 00%) were improved. There were 4 patients recurrence during the follow-up.
CONCLUSION
The direction and duration time of induced nystagmus are available to diagnose the HSC-Cup. The lesion side may determined according to the intensity of induced nystagmus. Lying position avoiding normal side and oral-taken betahistine mesilate tablets is an effective treatment methods for HSC-Cup.

AIM: To observe the effects and safety of clopidogrel used in percutanous coronary intervention (PCI) while acute occlusions of coronary arteries happened. METHODS: 92 patients with acute occlusions of coronary arteries were treated through PCI and they were randomized equally into following groups: clopidogrel group (CPG group) and ticlopidine group (TCP group). Each patient was treated with clopidogrel 25 mg bid or ticlopidine 250 mg bid for 4 weeks after PCI. RESULTS: Compared with the control group, there was not significantly difference in platelet aggregation ( 45.36 ? 2.98 vs 51.60 ? 2.56 ) and clinical effects ( 97.95 % vs 93.02 %) after 3 weeks. The proportion of patients with adverse events who had to release the treatment was 2.04 % (CPG group) and 16.27 % (TCP group). CONCLUSION: The clinical effect of clopidogrel is similar to ticlopidine and shows less adverse events.

OBJECTIVE:
To explore the clinical signification of screening 16 target deafness mutations in GJB2, GJB3, SLC26A4, WFS1 and mitochondrial DNA 12S rRNA in 135 children patients with non-syndromic sensorineural hearing loss (NSHL) in Zibo City, Shandong province.
METHOD:
Peripheral blood samples of 135 subjects in the study diagnosed as NSHL were collected; Polymerase chain reaction (PCR) and direct sequencing were used to analyze the 16 mutation spots.
RESULT:
Sixty-two cases of 135 patients (45.9%, 62/135) were found out to be carries of at least one pathogenic gene mutation. Among them, 24 cases (17.8%, 24/135) had two mutated alleles (homozygote and compound heterozygote), and 38 cases (28.1%, 38/135) were single mutant carriers. Among all the children patients, 30 cases (22. 2%, 30/135) had SLC26A4 mutations, and 19 cases (14.1%, 19/135) had GJB2 mutations. In the study 86 Mutant alleles were detected, and the allele frequency of SLC26A4 c. 766_2A > G and GJB2 c. 235delC was 11.11% (30/270) and 8.5% (23/270) respectively. The allele frequency of SLC26A4 c. 2168A > G and WFS1 c. 2158A > G is 2.6% (7/270).
CONCLUSION
SLC26A4 mutation is the primary cause of the patients with NSHL in this study, and GJB2 mutation is the secondary. The most common mutant form is c. 766_2A of SLC26A4, and the second is c. 235delC of GJB2. GJB3 and WFS1 mutations were detected, whereas mtDNA mutations were not found out in this study.

OBJECTIVE:
To objectively evaluate the voice rehabilitation status in different period after treatment of Tis--T1 glottic carcinoma by CO2 laser with voice parameters.
METHOD:
A retrospective review of 41 cases with Tis--T1 glottic carcinoma treated by CO2 laser was performed, 23 cases were stage Tis (Tis group) and 18 cases with stage T1N0M0 (T1 group). The range of excision of the lesion by CO2 laser was according to the different stages of the tumor, and ensured theoperation negative margin was by intraoperative frozen pathological examination. We tested and compared the actual voice (coritaine F0, Jitter, Shimmer, NNE and MPT) of 30 cases of healthy middle-aged and old male(normal group) and all the patients at one day prior to operation, three months, six months and one year after operation respectively, which was to evaluate the voice rehabilitation status in different period after operation objectively.
RESULT:
Postoperative pathological examination revealed, 23 cases were squamous epithelium severe atypical hyperplasia, 16 cases were well differentiated squamous cell carcinoma, and 2 cases were moderately differentiated squamous cell carcinoma. Palatoglossal arch mucosal tear occurred in 3 patients. Respiratory difficulties were not seen in all cases, and normal oral feeding was obtained in all cases in postoperative three days. All patients were followed up for one year. There was statistical significance in F0, Jitter, Shimmer of both Tis group and T1 group after operation in different periods(P<0.05). But there was no statistical significance in NNE and MPT between six months and one years after operation in the two groups(P>0.05).
CONCLUSION
CO2 laser surgery is an effective treatment for early glottic carcinoma. Postoperative vocal function was improved in varying degrees, and voice quality gradually improved with the rehabilitation time. Partly objective parameters reflecting the vocal function gradually stabilized after half a year after operation.

Objective:To investigate the clinical efficacy of laparoscopic resection of retrorectal cystic lesions.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 58 patients undergoing laparoscopic resection of retrorectal cystic lesions in the Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from August 2012 to August 2019 were collected. There were 5 males and 53 females, aged from 15 to 70 years, with a median age of 38 years. All the 58 patients underwent laparoscopic resection of retrorectal cystic lesions and the combined operation through the transsacral approach was chosen according to the patient condition. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative histopathological examination; (4) follow-up. Patients were followed up regularly using outpatient examination once every 6 months during the first postoperative year and once every 12 months after the first postoperative year. The recurrence of cysts was evaluated by computed tomography or magnetic resonance imaging examinations during the follow-up up to August 2020. Measurement data with normal distribution were represented as Mean± SD and measurement data with skewed distribution were described as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations: of the 58 patients, 54 cases underwent laparoscopic resection of retrorectal cystic lesions and 4 cases underwent laparoscopic resection of retrorectal cystic lesions combined with the transsacral approach operation. One of the 58 patients who had a huge cyst surrounding the rectum underwent transverse colostomy after repairing the damage of separated posterior wall of rectum. Two cases underwent preventive transverse colostomy because the external rectal wall heat injury could not be excluded after separation of the tight adhesion between cyst and rectum. The operation time and volume of intraoperative blood loss were (123±56)minutes, 20 mL(range, 5?500 mL) of 54 cases who underwent laparoscopic resection of retrorectal cystic lesions and (232±38)minutes, 90 mL(range, 30?800 mL) of 4 cases who underwent laparoscopic resection of retrorectal cystic lesions combined with the transsacral approach operation, respectively. (2) Postoperative situations: 7 of the 58 patients had complica-tions. Of the 7 patients, 2 cases had postoperative rectal fistula and were cured after the treatment of transverse colostomy combined with pelvic drainage, 2 cases had postoperative urinary tract infection and were relieved after anti-infection treatment, 2 cases had urinary retention after removal of catheter and were recovered after 3 weeks of re-indwelling catheter, and 1 case had poor incision healing of transsacral and was healed after wound dressing change. The duration of postoperative hospital stay of the 58 patients was (7±4)days. (3) Postoperative histopathological examination: results of the postoperative histopathological examination showed that there were 26 of 58 patients with epidermoid cyst, 20 patients with teratoma (2 cases with mature teratoma accompanied by mucinous adenocarcinoma and 1 case with mature teratoma accompanied by neuroendocrine carcinoma), 10 patients with dermoid cyst, and 2 patients with tailgut cyst. (4) Follow-up: 57 of the 58 patients were followed up for 2-85 months, with a median follow-up time of 51 months. Of the 57 patients who were followed up, 1 patient was diagnosed with buttock subcutaneous cyst at postoperative 8 months and treated with local excision, 1 patient was diagnosed with a small presacral cyst recurrence by pelvic magnetic resonance imaging at postoperative 6 months and continued follow-up as the cyst without obvious enlargement, and the other 55 patients had no cyst recurrence.Conclusion:The laparoscopic resection of retrorectal cystic lesions is safe and feasible.
