OBJECTIVETo investigate the long-term clinical effects of modified double Endobutton technique for the treatment of acromioclavicular joint dislocations of Tossy type III.

METHODSA retrospective study was done in 42 patients with acromioclavicular joint dislocations of Tossy type III treated with modified double Endobutton technique from December 2008 to December 2010. There were 24 males and 18 females, ranging in age from 21 to 56 years old (averaged, 32.5 years old). All the patients were treated with open reduction, coracoclavicular ligament reconstruction using double Endobutton technique, and repair of acromioclavicular ligament. The Karlsson system was used to evaluate therapeutic effects. The distance from coracoid to clavicle was measured to evaluate reduction loss.

RESULTSAll the patients were followed up, and the duration ranged from 2.0 to 3.2 years (averaged,2.4 years). According to Karlsson system, 32 patients got an A degree and 10 patients got a B degree at three months post-operatively; 26 patients got an A degree and 16 patients got a B degree at the latest follow-up; 6 patients got an A degree at 3 months after operation lowered to B degree at the latest follow-up. The coracoid-clavicle distance increased from (26.91 +/- 0.91) mm at 3 months after operation to (27.41 +/- 1.10) mm at the latest follow-up. Te patients treated with over-reduction during operation or with heavy physical labour work after operation had obvious widened coracoid-clavicle distance. Bone absorption was found around the plate in most cases, mainly in the clavicular side.

CONCLUSIONTreatment for acromioclavicular joint dislocations of Tossy type III with modified double Endobutton technique has satisfactory early clinical results. But with time passing, loss of reduction and bone absorption around the plate could be observed, and clinical outcomes of some cases downgrade during the long-term follow-up.

AIM:To improve accuracy of the diagnosis of primary conjunctival masses(PCM) through analyze the clinicopathological characteristics and pathogenic causes of 422 cases of PCM.METHODS:Clinical manifestations, histological characteristics and immunopheno types were reviewed.Relevant literatures were reviewed.RESULTS:Benign conjunctival masses were 403 cases (95.5%).Those included masses from squamous cell papilloma (71 cases, 17.6%), conjunctival cyst (68 cases, 16.9%), inflammatory masses (62 cases, 15.4%), pigmented nevus (60 cases, 14.9%), lipoma (58 cases, 14.4%).Malignant conjunctival neoplasms were 19 cases (4.5%).Those included tumors from B Cell Lymphoma (6 cases,31.6%), melanoma (6 cases,31.6%), and squamous cell carcinoma (5 cases, 26.3%).Different types of primary conjunctival masses were induced by the same cause.CONCLUSION:The pathological types of primary conjunctival masses are various and the majority of which is benign.For the diagnosis of primary conjunctival masses, morphological analysis, immunohistochemical examination shoud be combined to increase the diagnostic accuracy and decrease misdiagnosis rate.

To solve separating problem of natural soda, fifty-seven strains screened from soil, floul water and activated mud were of flocculating activity. Two strains of bacteria, which were screened from above mentioned strains have higher activity and better steady than the whole culture liquid of bacteria was observed that its flocculating use to natural soda was strong and the mean flocculating rate of two strains were 79.80% and 87.% respectively.

Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

Objective To assess the efficacy and safety of two different protocols of ketogenic diet (KD)-eating on demand or eating at regular intervals for refractory epilepsy in children.Methods Sixty children with refractory epilepsy were randomly divided into eating on demand group (n =30) and eating at regular intervals group (n =30) by random number table method.After taking the whole amount of KD,the capillary blood ketone and glucose level and urine ketone were monitored every 6 hours in 72 continuous hours.Seizure frequency and onset time were recorded.Antiepileptic efficacy and diet tolerability of the two groups were evaluated on 4 weeks,12 weeks,24 weeks and 48 weeks after initiating the diet.Adverse effects were monitored.Results After treatment of 4 weeks,the complete seizure remission rates of eating on demand group and eating at regular intervals group were 33.3％ (10/30) and 30.0％ (9/30) respectively,which suggested a comparable efficacy for two groups (P ＞ 0.05).The day when KD started to work was averaged (6.18 ± 2.42) d and (8.63 ± 2.63) d respectively.The group of eating on demand showed a faster onset of action (P ＜0.05).After treatment of 12 weeks,24 weeks and 48 weeks,complete seizure remission rates of eating on demand group were 30.0％ (9/30),34.8％ (8/23) and 36.8％ (7/19) respectively;the eating at regular intervals group were 33.3％ (10/30),30.4％ (7/23) and 44.4％ (8/18) respectively.The two groups had no significant difference (P ＞ 0.05).One year later,the treatment retention rates of the two groups were 63.3 ％ (19/30) and 60.0％ (18/30) respectively.There was no significant difference (P ＞ 0.05).The adverse effects mainly including transient gastrointestinal symptoms and metabolic disturbances were mostly tolerable and curable.Conclusion The two different protocols of KD-eating on demand and eating at regular intervals are both effective and well-tolerated for refractory epilepsy in children.While protocol of eating on demand is more easier to achieve ketotic state and the effect is more quickly,so it can be more easily received by children.Therefore in clinical practice,we can choose flexible eating time according to children's eating habits,which can improve the therapeutic compliance.

ObjectiveTo investigate the effect of rehabilitative treatment on different groups of infants with cerebral palsy in different age, sickness extent and rehabilitative period.MethodsBy the prospective method, 90 patients from 3 to 36 months old were randomly divided into three groups including 3 to 12 months, 13 to 24 months and 25 to 36 months with 30 cases each. Every 10 cases in light, moderate and severe degrees were given rehabilitative care for 2 months and 3 months respectively. The personal ADL of every case was evaluated at the initial and the final state. The compared score was analyzed with T test.ResultsComparing the groups of different ages, there were prominent differences of treatment under the same sickness, among the light, moderate and severe degrees(P<0.01). The rehabilitative treatment effect of 3 months was better than that of 2 months. Furthermore the effect of the group of 3-12 months was better than that of 25-36 months.ConclusionsThe rehabilitative care is prominently effective in the light and moderate groups , the former is better and within 3 months is better than 2 months. The younger infant is, the better the rehabilitative treatment is.
