Objective To construct a traditional Chinese medicine diagnostic scale suitable for chronic obstructive pulmonary disease(COPD)with lung qi stagnation syndrome,and to verify the reliability and validity of the scale.Methods Preliminary research has identified 16 core symptom items for lung qi stagnation syndrome.Diagnosis and scale collection were conducted on 95 patients using both traditional Chinese and Western medicine,with scores of 0,1,2,and 3 based on the severity of symptoms.By frequency t-test,discrete trend,and Cronbach's alpha coefficient screening items were used to evaluate the internal consistency of the scale,Spearman Brown coefficient was used to evaluate the stability of the scale,and exploratory factor analysis was used to determine the structural validity of the scale.Results Partial items were excluded and the final 11 scale items were confirmed.The overall Cronbach's alpha coefficient of the scale was 0.719,and the overall Spearman Brown coefficient was 0.647;The KMO test value is 0.612>0.5,The significance level of Bartlett's sphericity test is P<0.01;Extracting common factors with feature roots greater than 1,the maximum total variance explained by 64.122%was achieved when extracting four common factors.The common factor loadings for each item were all greater than 0.5,and the variance was all greater than 0.4,indicating good structural validity of the scale.Conclusion This study constructed and validated a traditional Chinese medicine diagnostic scale for COPD with lung qi stagnation syndrome.The scale has good reliability and validity,providing a reliable tool for clinical diagnosis and treatment.

Objective:To summarize the clinical and imaging presentations of the pontine tegmental cap dysplasia (PTCD).Methods:The clinical, high resolution CT(HRCT) and MRI materials of 4 patients with PTCD between August 2007 to December 2024 were retrospectively analyzed. Among these, there were 2 males and 2 females, their ages ranged from 10 months to 16 years.Results:Of 4 PTCD patients, severe or profound severe hearing loss ( n=8 ears), developmental delay, hypotonia and severe facioplegia ( n=3 cases) were found. On HRCT, all of 4 cases were associated with temporal anomalies [including a narrow bony cochlear nerve canal ( n=8 ears), duplicated (each n=4 ears) or narrow ( n=1 ear) internal auditory canal, enlarged vestibular aqueduct ( n=2 ears), enlarged vestibules and dysplastic lateral semicircular canals ( n=3 ears), ossicular deformation( n=2 ears). The stenosis of the labyrinthine segments of the facial nerve canal ( n=3 ears) and facial nerve canal ectopia(n=6 ears)], atrial or ventricular septal defect (each n=1 case), thoracic or lumbar vertebral anomalies and ribs fusion ( n=3 cases). On the brain MRI, the variable flattening of the ventral pons and dysmorphism of the dorsal upper pons cap-like bulging and protruding in the fourth ventricle were shown in all cases, the vermian and cerebellar peduncles hypoplasia gave rise to a molar tooth appearance. The dysplastic ( n=3 ears), aplastic( n=5 ears) cochlear nerves and dysplastic facial nerves ( n=3 ears) were found. Conclusion:The PTCD patients usually present severe hearing loss, developmental delay, hypotonia, and facioplegia. The flattening of the ventral pons and the dorsal upper pons cap-like bulging usually with duplicated internal auditory canal and severe facial and auditory nerves dysplasia are its imaging features.

OBJECTIVETo investigate the clinical and imaging characteristics of chronic otitis media with intact tympanic membrane.

METHODTen patients were retrospective studied in the department of otorhinolaryngology of Guangdong general hospital from December 2006 to January 2015. The clinical characteristics of their manifestations, audiology and imaging examinations were analyzed.

RESULTSAll the cases could be divided into two groups: the intracranial complication group who was primarily diagnosed as intracranial complications, and the hearing loss group who primarily complained of hearing loss. Five cases belonged to the first group, which include 1 cerebellar abscess, 3 meningitis and 1 meningoencephalitis, 2 of them were profound hearing loss, 2 were mixed hearing loss, and 1 was normal hearing. The other 5 cases belonged to the hearing loss group, 3 were mixed deafness, 2 were conductive deafness. All the case showed positive high-resolution computed tomography (HRCT) features. In the first group, four cases showed the soft tissue shadow in tympanic antrum/superior tympanic pouch and 1 case showed a wide damage of skull base, in addition to intracranial complications. In the second group, five cases showed soft tissue imaging in tympanic antrum/superior tympanic pouch. Pathology showed that 2 cases were cholesterol granuloma(one was in the first group and the other was in the second group), 4 were intracranial inflammatory(the first group) and 4 were cholesteatoma(the seond group).

CONCLUSIONSIn chronic otitis media with intact tympanic membrane, intracranial complications may be the primarily diagnosis, which should be paid much attention by multidisciplinary team. HRCT and audiology were valuable for early diagnosis.

Objective To identify and assess whether circumferential electrocautery is useful to improve outcomes after primary total knee replacement.Methods We searched MEDLINE,EMBASE,PubMed,SpringerLink,Web of Knowledge,OVID CINAHL,OVID EBM and Google Scholar,and included articles published through January 2014.This study used the methods of meta-analysis to assess whether circumferential electrocautery could improve anterior knee pain and knee function after total knee replacement,and identified the function of circumferential electrocautery in total knee replacement.Results A total of eight articles met the inclusion criteria.Among the 1 048 cases included in the analysis,526 cases had patellar denervation,and 522 cases were in the control group.The meta-analysis revealed no significant difference in the incidence of anterior knee pain (P =0.18) and visual analogue scale (VAS) (P =0.23) between two groups.However,patellar score (P =0.01),Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score (P ＜ 0.01),and range of motion (ROM) (P ＜ 0.01) indicated that circumpatellar electrocautery improved clinical outcomes compared to non-electrocautery groups.Conclusions The results indicated that circumferential electrocautery of the patellar did not significantly improve anterior knee pain relative to non-electrocautery techniques.However,circumferential electrocautery significantly improved patients' knee function after surgery.Therefore,circumferential electrocautery might be beneficial to the outcome of primary total knee replacement surgery without patella replacement.

OBJECTIVE: To investigate the correlation betwen varying degrees of non-acute tinnitus and anxiety and depression. METHOD: Seventy-seven outpatients with non-acute tinnitus as their in chief complaint were submitted to Tinnitus Handicap Inventory(THI), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS). RESULT: THI and its three subscales were found to have significant correlations with SAS and SDS. The group (THI ≥ 38) had more anxiety and depression than the mild (THI < 38). Significant correlations were also observed between THI, SAS and SDS in the group with THI ≥ 38, in contrast with the group of THI < 38. CONCLUSION Patients with THI ≥ 38 suffered from severe anxiety and depression than the mild. Doctors should pay more attention to these patients, especially their psychological disorders.

OBJECTIVE: To evaluate the significance of additional 180-degree roll test (RT) in the determination of affected side in patients with horizontal semicircular canal benign paroxysmal vertigo (HSC-BPPV). METHOD: One hundred and six patients with HSC-BPPV were performed the 90 degree RT. patients whose affected side cannot be determined by 90 degree RT were performed 180 degree roll test. RESULT: The affected side was deter- mined by the 180 degree RT in 10 cases in which the lesion side cannot be determined by the 90-degree RT. CONCLUSION The affected side of HSC BPPV was able to be determined by 180 degree RT when it not possible to be determined by 90 degree RT. 180 degree RT is an effective and simple additional method.

OBJECTIVE: To study the management of basic parameters related to individual piston shaping on malleostapedotomy by MDST 3D reconstruction and microanatomy and to assess the accuracy of MDST method. METHOD: Ten Chinese temporal bones without ear diseases were numbered randomly and scanned by GE Light Speed Ultra 64 rows of spiral CT. 3D structure of ossicular chain were reconstructed by MPR and VR methods in AW4. 1 workstation. Then measurements of distances between stapes head to stapes footplate (A line), and manubrium to stapes head (B line), and manubrium to stapes footplate (C line), angle between line A and line B (angle AB) are completed. After that, all samples of temporal bone were undergone canal wall down mastoidectomy under microscope and the relevant measurements were completed. RESULT: The MPR and VR technique of MDCT reconstructed ossicular chain clearly, and revealed the spatial relationship between every structure stereoscopically. Respectively, lengths of A, B, C line by MDST and microanatomy are (3.42 +/- 0.86) mm and (3.60 +/- 0.94) mm, (3.42 +/- 0.80) mm and (2.96 +/- 0.42) mm, (5.86 +/- 0.60) mm and (6.22 +/- 1.10) mm, while angle AB (141.05 +/- 30.07) degrees and (144.57 +/- 41.86) degrees. There are no statistically significant differences between two groups (P>0.05). CONCLUSION The MPR and VR technique of MDCT can clearly reconstructed the 3D shapes of the temporal bone and finish the exactly managements on A, B, C lines and AB angel which is crucial for shaping a individual piston on malleus-to-oval window surgery.
