Objective To propose a treatment protocol by videothoracoscopy in spontaneous pneumothorax. Methods One hundred and three patients underwent Video assisted thoracoscopic (VATS) treatment of spontaneous peumothorax and hemothorax. Indications included recurrent pneumothorax, persistent air leakage following conservative therapy, complicated hemothorax and CT scan identified bullae formation. Results No operative deaths occurred, conversion rate was 2.91%, recurrence rate was 0.97%, complication rate was 3.81% and mean postoperative hospital stay was 5.6 days. Conclusions VATS treatment of spontaneous pneumothorax is better than open chest surgery and also superior than conservative therapy.

Objective Some cases of lipid storage myopathy (LSM) are similar to the polymyositis(PM) in clinic.To study the muscle pathology is helpful as to making clear the diagnosis and elucidating the mechanism of the LSM. Methods 14 cases of LSM with high level of CK in serum were analyzed clinically and compared with their muscle morphological and histochemical changes.Results Muscle weakness and fatigue were the main complaints of these patients.Most of them had acute or sub acute onset,some of them had relapse courses.All of the muscle specimens showed typical accumulation of lipid in muscle fibers.Necrotic fibers were found in 9 cases,3 of them showed changes with the courses. Conclusion Muscle biopsies and histochemical studies are necessary to differentiate LMS with PM.The fiber necrosis and CK leakage in LSM may be caused by changes of the inter circumstance and the membrane disturbance of cells.

Objective To investigate the effects of ult rasonic cavitation on cell membrane cultured in vitro. Methods The rat pulmonary artery vascular smooth muscle cells were divided into three groups, control group, simple ultrasound radiation group and contrast plus ultrasound radiation group.The latter two groups were exposed to ultrasound(665 kHz, 0.5- W/cm 2) for 20 s but the last group with contrast agent. Immediately after the experiment or 24 hours after treatments, electron microscopic scanning was used to observe the membrane change. Results Compared with control group, the cell structure and cell surface had no apparent changes in the second group treated with ultrasound alone. In the third group, nearly 20% cells exhibited small holes with diameter mostly about 1-2 ?m in the cell surface and returned to normal appearance after 24 hours later. Conclusions Ultrasonic cavitation can cause small transient holes in cell surface and hence increase permeability of the cell membrane. It might be the main mechanism for gene delivery with ultrasound contrast agents.

Objective:To study the inhibitory role of BsAb(anti-human bladder cancer/anti-VEGF) on human bladder cancer growth.Methods:BsAb was used to treat animal models of BIU-87 cell lines.The tumor inhibition rate was calculated and the tumor microvessel density was detected by immunohistochemical techniques.Results:BsAb could significantly inhibit growth of tumor.And the tumor microvessel density was lower than that of the control group.Conclusion:BsAb could inhibit tumor growth by inhibiting angiogenesis. BsAb may become a new method for human bladder cancer treatment.

[Objective] To determine the efficacy of one-stage posterior deformity correction with transpedicular screw system and anterior radical debridement following reconstuction with titanium mesh cage for treatment of lumbar tuberculosis. [Methods]Forty-three patients with lumbar tuberculosis were treated operatively through anterior and posterior combined approach.The postoperative neurologic status (ASIA,2000),graft fusion,deformity correction and complications were observed and analyzed respectively.[Results]Forty-one patients were followed up for a duration of 24~36 months (mean 28.3 months).A solid fusion was achived in all cases.The neurologic function was improved in all patients in different grades.The mean kyphotic angle was corrected by 21.3 degrees,the angle loss was 1?~3?,the mean vertebral height was restored by 10.2 mm,the mean height loss was 2.4 mm.There was no recurrence of the tuberculosis infection.[Conclusion]One-stage posterior deformity correction with transpedicular screw system and anterior radical debridement following reconstuction with titanium mesh cage is a safe and effective method in the surgical management of lumbar tuberculosis.

Thirteen albino rats with body weight approximately from 0.4～0.6 kg were used in the experiment. Each was injected with 0.1 ?l of 30％ HRP (Sigma Type Ⅵ) solution into one of several portions of the cingulate gyrus. Two days after the injection, the animals were sacrificed and processed with Nauta's DAB and Edward's O-D methods. The results were as follows:1. Area 25 and 32 receive the fibers from areas 3, 1, 2 and globus pallidus on the ipsilateral side, and from areas 10, and 24, caudoputamen nucleus, lateral nucleus of the hypothalamus, intercavernous nucleus of the stria terminalis on both sides. The labeled cells were also found in areas 25 and 32 on contralateral side.2. Area 24 receives fibers from area 32 and the lateral part of the dorsomedial nucleus of the thalamus on the ipsilateral side, and from area 10, the anterior olfactory nucleus, caudoputamen nucleus, and septal nucleus on both sides and from areas 4 and 24 on the contralateral side.3. Areas 23 and 29 receive the fibers from areas 24,17, and 18 on the ipsilateral side, and from areas 23,29,32,25 and rostral part of the linear nucleus on the contralateral side.The results prove that the cingulate area widely receives the afferent fibers from cortex, thalamus, hypothalamus and midbrain.

With the understanding of autoimmune encephalitis many novel types of autoimmune encephalitis and related antibodies have been identified. There are some cases of autoimmune encephalitis with autoantibody overlapping syndromes or phenotype overlapping syndromes, which bring challenges to diagnosis and treatment in practice. The relevant literature was reviewed and the clinical characteristics, pathological mechanism and treatment of overlapping syndromes associated with autoimmune encephalitis were summarized, in order to provide a reference for the management of autoimmune encephalitis with overlapping syndromes.

Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

ObjectiveTo investigate the clinical and pathological characteristics of dermatomyositis with muscular perifascicular atrophy (PFA).MethodsA series of 104 consecutive patients clinically and pathologically diagnosed as dermatomyositis by muscle biopsy in our laboratory from December,2003 to August,2011,were enrolled in this study. Muscle biopsy of all the enrolled patients had shown PFA of muscle fibers.ResultsAmong the 104 patients,34 were males and 70 were females with a mean age of 45 years old.Among them,8 cases had normal electromyogram;42 had normal serum creatine kinase level;11 were diagnosed as carcinoma;75 were found to be combined with interstitial lung disease (ILD).Based on morphologic changes of muscle biopsy,they were divided into pure PFA group with 54 cases and PFA plus focal damage group with 50 cases.Compared with the pure PFA group,there was prominent mononuclear cell infiltration into perimysial intermediate sized vessels and membrane attack complement (MAC) deposition in the intramuscular capillaries in the PFA plus group.Skin biopsy had been taken in 12 cases together with muscle biopsy and had shown the border effectof both PFA and interface dermatitis in muscle and skin.ConclusionsOur study suggests that chronic immune vascular damage and insufficiency in dermatomyositis may cause ischemia and focal myofiber damage in watershed regions. The incidence of ILD in our dermatomyositis patients with PFA is high.
