Objective To analyze the effect of acromio-humeral interval on the occurrence of subacromial impingement syndrome (SIS) after the clinical application of clavicular hook plate in acromioclavicular joint dislocation (Tossy Ⅲ). Methods From July 2005 to October 2008, 63 cases of acromioclavicular joint dislocation (Tossy Ⅲ) were treated with clavicular hook plate. There were 48 males and 15 females with an average age of 33.6 years (range, 21-53 years). The relationship of the acromio-humeral interval (AHI)were analysed between the two groups by X-ray measurement. The AHI and plate-humeral interval (PHI)were measured on X-ray film to detect difference between the two groups. Results After the operation, all t he 63 cases were divided into two groups according the occurrence of SIS. There were 14 cases in the group of SIS and 49 cases in the group without SIS. The mean follow-up was 12.2 (average, 6-15) months.The average AHI of was (8.5±2.1) mm and (9.7±2.6) mm in the group of SIS and the group without SIS respectively. The difference between the two groups was statistically significant. The average PHI of the group of SIS and the group without SIS was (6.1±2.8) mm and (6.8±2.4) mm respectively. There was no difference between the two groups. After removal of the clavicular hook plate, the clinical sign disappeared in the group of SIS. According the Karlsson scoring system, the excellent and good rate of the shoulder function was 100%. Conclusion The occurrence of SIS after the clinical application of clavicular hook plate has related to the width of the subacromial interval. The syndrome could be treated by the removal of clavicular hook plate.

Objective To investigate the levels of estrogen,progesterone,follicle-stimulating hormone (FSH),and luteinizing hormone (LH) in serum and the expression of ER,PR,FSH receptor (FSHR),and LH receptor (LHR) in thyroid tissues of patients with different types of thyroid nodules.Methods Serum levels of estrogen,progesterone,FSH,and LH were measured by chemiluminescence and expression of ER,PR,FSHR,and LHR in thyroid tissue was detected by immunohistochemistry in female patients with thyroid adenoma (n＝97),nodular goiter (n＝103),thyroid papillary cancer (n＝208),poorly differentiated thyroid carcinoma (n＝17),or undifferentiated thyroid carcinoma (n＝10) and in normal controls (n＝60) from Dec.2009 to Dec.2014 in Department of Thyroid Surgery of the First Hospital of Jilin University.Results The positive rates of serum estrogen level and ER expression were significantly greater in patients with various types of thyroid nodules than in normal controls.The positive rates of ER expression were significantly lower in various types of thyroid nodules than in normal thyroid tissues,especially in poorly differentiated carcinoma and undifferentiated carcinoma.The negative rates of serum progesterone level and positive rates of PR expression in thyroid tissue were significantly greater in patients with thyroid adenoma,nodular goiter,or thyroid papillary cancer than in normal controls.The positive rates of serum FSH and LH levels and FSHR and LHR expression were significantly greater in the thyroid adenoma group than in other groups.Conclusions The occurance of thyroid nodules might be related to sex hormone.The combined detection of serum levels of sex hormones and expression of their receptors allows for a differential diagnosis and evaluation of the degree of differentiation among various types of thyroid nodules.

Objective To analyze the clinical features,curative effect and prognosis of extra-pulmonary infections by mycoplasma pneumoniae(MP).Methods ELISA was used to detect anti-MP IgM and IgG.Case histories of 226 patients,whose nasopharyneal lotione and respiratory secretions were positive of virus and bacteria respectively,was analysed retrospectively.Results One hundred and eighteen of the 226 (52.2%) cases suffered from extra-pulmonary infection.Of these infections 38.98%,33.89%,21.11% and 17.79% were found in digestive, urinary, cardiovascular systems and serous membrane respectively.All of the cases were improved after treatment with macrolides antibiotics.All cases were MP IgM positive,35.5% cases were IgG positive.Spatum MP positive rate was 32.2%.Positive rate of cold-agglutination test was 47.46%.Conclusions MP infection may cause many extra-pulmonary complications.When multi-organ infections can not be explained with bacterial and viral infections,MP infection should be considered.

Objective To evaluate the differences of the thinnest-point corneal thickness (TCT) decrease after three different corneal crosslinking (CXL) protocols for progressive keratoconus.Methyds Retrospective clinical case study.From August 2010 to November 2015,consecutive 85 patients (110 eyes) with progressive keratoconus were enrolled and treated with CXL in Department of Opthalmology,Navy General Hospital.21 patients of 25 eyes underwent standard epithelium-off corneal crosslinking (S-CXL),14 patients of 22 eyes underwent 1 g · L-1 riboflavin-sodium lactate Ringer's solution iontophoresis-assisted CXL (I-CXLa),and 50 patients of 63 eyes underwent 0.1％ riboflavin-distilled water solution I-CXLb.Preoperative and postoperative TCT were measured by ALLEGRO oculyzer.The differences of TCT decrease after treatment were compared among the three CXL protocols.Results The differences of TCT from baseline after 3 months,6 months and 12 months in the S-CXL group were (-14.93 ±27.16) μm,(-31.94 ±22.89) μm,(-27.71 ±26.01) μm,respectively,the I-CXLa group were (-20.14 ± 19.09) μm,(-10.10 ± 24.28) μm,(-7.11 ± 22.26)μm,respectively,the I-CXLb group were (-28.08 ± 26.14) μm,(-21.08 ± 25.62) μm,(-15.91 ± 19.19)μm,respectively.Three months after treatment,the differences of TCT decrease in the three groups was not statistically significant (P =0.188);Six and 12 months after treatment,the differences between S-CXL and I-CXLa were statistically significant (all P ＜0.05),but the differences between S-CXL and I-CXLb,between I-CXLb and I-CXLa showed no significant difference (all P ＞ 0.05).Conclusion Six and 12 months after treatment,TCT decrease is related to the CXL protocol.TCT decrease degree may reflect the intensity of crossinking.TCT decrease in I-CXLb is smaller than that in S-CXL,but there is no statistical difference.

This study was aimed to summarize and analyze acupoint selection rule of acupuncture in the treatment of primary dysmenorrhea in recent years,and to guide acupoint selection and compatibility in clinical practice.Relevant literatures in recent years were retrieved from the China National Knowledge Infrastructure (CNKI) full-text database.And then,literatures involving acupuncture prescriptions were summarized.Data were integrated and input.Finally,the SPSS software was combined to analyze the data of acupoint selection in the acupuncture prescription to achieve the conclusion.The results showed that in the acupuncture treatment of primary dysmenorrhea,the main meridian selections were the Ren Meridian and the Spleen Meridian of Foot Taiyin.The generally used acupoints were SP6-Sanyinjiao,RN4-Guanyuan,SPS-Diji,and etc.The multi-point compatibility therapy was used.It was concluded that although the advantages of acupuncture in the treatment of primary dysmenorrhea are prominent,the pathogenesis is mainly related to the liver,spleen and kidney,which are recognized by most physicians.However,there are still large differences in acupoint compatibility and acupoint selection.Hence,there are still no unified,scientific and standardized diagnosis and treatment standards.Further exploration should be made to guide clinical practice.
