The effects of taurine on the size of myocardial infarction and the changes of activity of SOD , and the levels of MDA and NO in myocardium and plasma of rats with myocardial ischemia and reperfusion injury were observed. Results In rats with myocardial ischemia and reperfusion injury, the taurine could reduce the size of myocardial infarction (P

Background Corneal neovascularization ( CNV ) is a complication of many ocular surface diseases.It often worsen the pathological course.Effective therapy for CNV is still researching. Objective This study was to investigate the inhibitory effect of irradiation on CNV. Methods CNV models were established in 70 right eyes of 70 clean Wistar rats by corneal alkali burning.The models were randomized into β ray 10 Gy once irradiation group( 2 eyes),β ray 7 Gy multiple irradiation group( 17 eyes),β ray 10 Gy multiple irradiation group( 17 eyes),1％ cyclosporin A ( CsA ) eye drops group ( 17 eyes) and model group ( 17 eyes),and 6 matched normal rats were used as normal controls.All treatments started from the first day of the corneal alkali burning.CNV length and area were measured under the slit lamp every day.Corneal samples and homogenate were prepared 3,5,7 days after corneal alkali burning.The expressions of bcl-2,bax,vascular endothelial growth factor(VEGF) in rat corneas were detected by immunochemistry,VEGF proteins and VEGF mRNA were detected by Western blot and reverse transcription polymerase chain reaction (RT-PCR),respectively. Results Corneal ulceration was found in the βray 10 Gy once irradiation group and β ray 10 Gy multiple irradiation group.CNV length and area were much less in the β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group compared with the model group on the seventh day after experiment( length:q=14.40,24.20,P＜0.01 ;area:q=17.80,14.00,P＜0.01 ).Immunochemistry revealed that compared with the model group,expressions of bcl-2 and VEGF proteins were weaker,but the expression of bax protein was stronger in the β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group.RT-PCR showed that the expression of VEGF mRNA in cornea was lower in the β ray 10 Gy multiple irradiation group,β ray 7 Gy multiple irradiation group and 1％ CsA eye drops group in comparison with that in model group,and the results from Western blot showed the same pattern as RT-PCR. Conclusions Low dose irradiation of 90Sr-90Y ophthalmic applicator inhibits CNV formation after alkali burn.The study provide a new understanding of the irradiation for the treatment of CNV.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

Objectives To investigate the significance of electronic bronchoscopy and bronchoalveolar lavage in diagno-sis and treatment in children with pulmonary mass lesion. Methods A total of 74 hospitalized children from January 2011 to June 2012 whose imaging examinations showed massive patchy shadow were examined and treated by electronic bronchoscopy and bronchoalveolar lavage. Their clinical data were retrospectively analyzed. Results The major cause for the massive shadow was infection according to electronic bronchoscopy examination (68/74, 91.89%), 65 cases of them were lobar pneumonia, 3 cas-es were pulmonary tuberculosis followed by 5 cases of foreign body (6.76%) and one case of pneumorrhagia (1.35%).The lower left lung was the most frequently seen site of infection, followed by lower right lung. The agreement between infection sites and imaging examination was 97.30%. Bronchoalveolar lavage fluid showed that the primary pathogen of lobar pneumonia infection is Mycoplasma pneumoniae (MP) (42/65, 64.62%). The highest detection rate of MP was found in preschool group and the detec-tion rate between different age groups indicated statistically significant difference (P<0.01). The imaging examination showed pulmonary lesions in 61.54%children with lobar pneumonia improved significantly in one week. The improvement rate of pul-monary lesions was higher in infected children with short duration (1-2 weeks, 90.91%) between disease onset and electronic bronchoscopy inspection than those with longer duration (2-3 weeks, 51.72% and >3 weeks, 35.71%) (P<0.05). Conclusions Electronic bronchoscopy and bronchoalveolar lavage play dual roles in etiological diagnosis and therapy in children with pulmo-nary mass lesion.

Objective To assess the long-term outcome of unilateral adrenaletomy in patients with adrenocorticotropic hormone independent macronodular adrenal hyperplasia (AIMAH).Methods The data from 82 cases of AIMAH were reviewed and summarized including clinical manifestations, endocrinological data, imaging findings and postoperative follow-up.Fouty-nine males and thirty-three females with a mean age of fifty years composed our series.Among the 82 cases, 41 demonstrated Cushing syndrome (CS), 74 presented with hypertension, 38 manifested diabetes mellitus, 35 complicated of osteoporosis and 11 of them with bone fracture, 39 complained of edema.Laboratory tests showed low ACTH plasma levels (＜ 2.2 pmol/L) in 62 of 79 cases.High level of 24-hour urinay free cortisol excretion(＞ 284.2nmol/L) was found in 67 of 79 cases.Elevated serum cortisol with loss of the circadian rhythm was presented in 55 of 60 cases.Failed to suppress cortisol secretion was observed in 61 of 63 conducted with low-dose dexamethasone suppression tests and in 47 of 53 implemented with high-dose dexamethasone suppression tests.Bilateral massively enlarged multinodular adrenal glands were found in all cases with CT or MR imaging.Unilateral adrenalectomy was performed in the larger side of adrenal gland in all 82 cases.All adrenalectomies were carried out including 47 in right sides and 35 in left sides, with 77 by retroperitoneoscopic approach and 5 by open retroperitoneal approach.Results Histopathological examination confirmed nodular hyperplasia of the adrenal cortex for all specimens.After a mean duration of 48.5 months, 80 of 82 patients were available for follow-up.Most clinical symptoms resolved within 6 months after operation.Cushingoid features disappeared in 58.5％ (24/41)of patients who initially presented with typical signs of Cushing Syndrome.Weight loss was seen in 56.3％ (45/80).Improvement of hypertension and diabetes was observed in 63.5％ (47/74) and 76.3％ (29/38) respectively.All the eyelids swelling and edema of the limbs subsided within 3 months.In long-term follow-up (more than 6 months), 82.9％ (63/76) had clinical and biochemical recurrence within a mean time of 14.6 months and 46.0％ (29/63) received contralateral adrenal surgery.Two patients died, one died from heart attack and another one died from pulmonary infection, 2 years and 7 years after unilateral adrenalectomy, respectively.Conclusions Unilateral adrenalectomy just has transient efficiency for AIMAH.Most patients will experience clinical and biochemical recurrence for a long period,and have to receive another operation for the contralateral hyperplastic adrenal gland.

Objective To observe the effect of bandage contact lens on cornea epithelial healing after Epi-LASIK,and to evaluate the efficacy and safety.Methods Prospective case-control study.The 92 cases(181 eyes) performing Epi-LASIK were devided into observation group and control group.The 46 cases(91 eyes) of the control group were covered with routine nursing and the other 46 cases (90 eyes) of the observation group were served with bandage contact lens after Epi-LASIK.The symptoms and signs,time of corneal epithelial recovery,visual acuity and pain of postoperation of the two groups were examined within one week.Results After Epi-LASIK treatment,there was no significant difference in visual acuity between the two groups(P ＞ 0.05).At the 1 st,3rd,and 7th day after Epi-LASIK treatment,the ache grading results of the observation group were (2.53 ± 0.62),(1.39 ± 0.71),(0.07-± 0.25);and the ache grading results of control group were (3.22 ± 0.79),(1.74 ± 0.49),(0.26 ± 0.49).Pain scores of observation group were significantly lighter than that of the control group (P ＜ 0.05).After Epi-LASIK treatment,the average time of corneal wound healing in the observation group and control group were (2.80 ±0.86) days and (4.07 ±0.68) days respectively.The average time of postoperative corneal wound healing in the observation group was shorter than control group(P ＜ 0.05).Conclusion The application of bandage contact lens on cornea epithelial healing after Epi-LASIK treatment can reduce the pain of patients and promote the recovery of cornea in myopia patients.

Objective To study the diagnosis and surgical treatment of adrenal cavernous hemangi -oma. Methods The data of one case with adrenal cavernous hemangioma was retrospectively reviewed .A 62-year-old female patient admitted in out hospital on 18th June, 2013 due to the paroxysmal hypertension for 10 years and finding the left adrenal mass for 2 months.Her highest blood pressure was 175/55 mmHg and the response for the drug treatment was poor .In recent 6 months, her blood pressure was unstable .Ab-dominal ultrasound showed a hypoechoic mass in left adrenal .Enhanced CT examination showed an irregular mass in the left adrenal gland , with the size of 4.5 cm ×2.5 cm ×3.9 cm,peripherally enhanced in arterial phase , contrast agent filling in portal venous phase , and high density in delay phase .Abdominal MR exami-nation showed a mass before abdominal aortic , with clear and smooth edge .The mass showed low signal in T1WI phase and high signal in T 2WI phase, which was considered as pheochromocytoma .24h urinary cate-cholamines showed that norepinephrine was 103.0 nmol, epinephrine was 9.8 nmol and dopamine was 18.9 nmol.Octreotide (99Tcm-TOC) showed slight high expression of somatostatin receptor .Preoperative diagnosis was left pheochromocytoma . Results After the preoperative medical preparation of phenoxybenzamine for 3 weeks, her blood pressure was maintained at 120-132/50-70 mmHg, with stuffy nose, warm hand and foot, and the weight gain of about 1 kg.The patient was undergone laparoscopic resection of left adrenal tumor under general anesthesia on June 24, 2013.The postoperative blood pressure returned to normal .And the left adrenal pathology was cavernous hemangioma .Following up for 5 months, the patient had normal blood pressure without the tumor recurrence . Conclusions The adrenal cavernous hemangioma is extreme-ly rare with high rate of misdiagnosis .For adrenal tumor with typical hemangioma imaging , the diagnosis of cavernous hemangioma should be considered .For tumors larger than 6 cm, surgery is recommended .The first choice of operative approach is laparoscopic resection of adrenal tumor , and normal adrenal tissue should be retained as far as possible.
