Objective We report the pathological features of lung in the dead patients with severe acute respiratory syndrome (SARS). Methods Post-mortem lung and pulomonary hilar lymph nodes tissues of 3 patients dead from SARS were studied by histology and immuhistochemistry with rabbit anti-Fas polyclonal antibody, mouse anti-PCNA, mouse anti- CD83,mouse anti-CD4 and mouse anti-CD8 monoclonal antibodies. Results The surface of lung from 3 cases were shown red or purplish red color. Histopathological examination showed that diffuse interstitial exudative or leakage inflammation and alveolar damages with a pronounced increase of of monocytes in the interval at various levels of progression and severity. There were hyaline-membrane formation, desquamation and apoptosis of type-2 pneumocytes in alveolar spaces. Fibrin thrombus and thrombo-embolism could be found in blood capillary and bronchial artery respectively. We observed some fibrin deposition in alveoli interval. No obviously giant-cell infiltrate within the alveolar lumen. The positive cell of proliferative cell nuclear antigen (PCNA) was rare. Fas antigen were expressed in a lot of type-2 pneumocytes, monocytes of the interval and pulomonary hilar lymph nodes. Comparison with the lymph nodes of chronic inflammation, there were obviously disorganization and attenuation of lymphocyte in lymph nodes of SARS. The proportion of CD4 positive lymphocytes were rare, but CD83 and CD8 positive lymphocyte seemed no decreased, relatively. The seminal changes such as decreased lymphocytes ,white pulp atrophy,hemorrhage and necrosis,and decreased expression of lymphocytes for CD4 antigen could also observe in spleen. Conclusions Severe damages of lung and immunological system damages might lead to death of patients with SARS.

Objective To observe pulmonary fibrosis in severe acute respiratory syndrome (SARS) and to discuss the mechanisms of pulmonary fibrosis in SARS. Methods Hematoxylin and Eosin staining (H&E), histology staining and immuno-histochemical staining (SP methods) were used to investigate the lungs from 4 autopsy cases. Antibodies against collagen type Ⅲ, ?-smooth muscle actin(?-SMA), Fas, FasL and transforming growth factor ?1(TGF-?1) were used for immunohistochemical studies. Results All these four lung tissues showed different degree of pulmonary fibrosis, including the organization of exudative fibrin, glomerulus-like fibrosis in alveolar spaces, the thickening of the alveolar septum, proliferation of fibroblasts, the hyperplasia of collagen fibers and the consolidation of lungs. Sirius red staining and collagen type Ⅲ staining showed the type Ⅲ and the type Ⅰ collagen fibers were the main components of the hyperplastic collagen fibers. ?-SMA were expressed in fibroblasts, immunoreactivity to Fas, FasL, TGF-?1 were all positive and located in plasma of pneumocytes, macrophages and lymphocytes. Conclusions The pulmonary fibrosis can be observed early in SARS patients and the pathogenesis may be involved in the co-effect of many effective cells, inflammatory mediators and cytokines.

The clearance of proteins differing in charge and/or size (IgG4, total IgG and albumin) was evaluated in 95 diabetic patients. Urinary IgG4 values increased in group mi-croalbuminuria. The increased urinary IgG4 excretion correlated significantly with the degree of albuminuria and diabetic retinopathy. Urinary total IgG levels increased obviously only in group with massive macroalbuminuria. The IgG4/total IgG ratio was highest in group mi-croalbuminuria, and its change had a special pattern. Urinary IgG4 and IgG4/total IgG ratio may be sensitive parameters in assessing early protein charge-selectivity impairment and in detecting incipient diabetic nephropathy.

Cirrhosis of the liver results in portal hypertension, which is a tortuous and dilated portal vein. The hemorrhage of digestive tract caused by dilation and rupture of lower esophagus and gastric fundus is the main cause of death in patients with cirrhosis. The treatment methods of digestive tract hemorrhage in liver cirrhosis include drug therapy, endoscopic hemostasis, interventional therapy to control hemorrhage and surgical hemostasis. These methods are mainly used to control hemorrhage and solve hypersplenism, but cannot solve the fundamental problem of cirrhosis. Stem cells can repair damaged liver cells and help restore liver function. Under the guidance of B-ultrasound, precise intrahepatic portal vein puncture and infusion of autologous bone marrow nucleated cells can improve cirrhosis through autologous bone marrow stem cells. Little damage to patients, little risk. Cell therapy combined with conventional therapy can treat both the symptoms and the root causes of digestive tract hemorrhage in cirrhosis.

OBJECTIVE: To study the pharmacological activities and toxicity of the crude alkaloids of Toddalia asiatica and to provide pharmacological data for the further development of this herbal medicine. METHODS: We observed the anti-inflammatory effects of the crude alkaloids of Toddalia asiatica, using xylol and agra to induce the turgidness and sodium carboxymethyl cellulose (CMC-Na) to induce leucocyte strolling in the rats. The analgesic effects were observed by body-distortion methods. The effects of alkaloids of Toddalia asiatica on hepatic function were observed by testing the contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum and calculating the liver index. The LD 50 and 95% creditability were calculated with developed Karber Method. RESULTS: The administration of alkaloids of Toddalia asiatica had the function of inhibiting the auricle swelling caused by xylol and joint swelling caused by agar and leucocyte migration caused by CMC-Na, decreasing the body-distortion of the rats. After two weeks administration, the contents of ALT and AST showed that there was no obvious difference between administered group and control group. The LD50 of the crude alkaloids of Toddalia asiatica was 1.622 g/kg and the 95% creditability was 1.29-2.03 g/kg. CONCLUSION: Toddalia asiatica has anti-inflammatory and analgesic effects, and there is no injury to the liver after long-term administration in rats.

Objective To investigate prevalence and risk factors of pelvic organ prolapse in women underwent routine gynecologic health care in Peking Union Medical College Hospital (PUMCH).Methods From Jan.2008 to Aug.2009,972 women underwent gynecological health care in PUMCH Were enrolled in this study.Questionnaires and pelfic examinations were given.The pelvic organ prolapse quantitive examination(POP-Q)system was used as the assessment tool.Results (1)Among all participants,the mean ages were(42±10)years(range 22 to 78 years),the mean height were(162±5)cm(range 142 to 180 cm),and the mean weight were(59±8)kg(range 42 to 91 kg).83.8%(815/972)of women were multipara.The mean total vagihal length(TVL)of 972 women was 8.20 cm.No women met the standard of pelvic organ prolapse, while 35.5% (345/972) of women presented mild posterior vaginal descent and 96. 7% (940/972) presented mild anterior vaginal descent, all of them were asymptomatic. (2) The length of genital hiatus (gh), TVL and C, D proximal to the hymen in nullipara were (2.26 ±0. 32), (8.08 ±0. 30), ( - 7.08 ± 0. 24) and ( - 8. 08 ± 0. 30) cm, which were significantly less than ( 2. 33 ± 0. 39 ),( 8. 22 ± 0. 35 ), ( - 7. 14 ± 0. 28 ) and ( - 8. 22 ± 0. 35 ) cm in multipara ( P < 0. 05 ). Ap and Pb proximal to the hymen of ( - 2. 87 ± 0. 22) and ( - 2. 87 ± 0. 22 ) cm in nullipara were significantly larger than ( -2.81 ±0.25) and ( -2.81 ±0.25) cm in multipara (P<0.05). When compared with nullipara, the incidence of posterior and anterior vaginal wall protrusion were increased ( OR = 1. 819). (3) The index of POP-P were compared among women at groups of 22 -34 years, 35 -49 years and more than 50 years (P <0. 05 ). Those index did not show statistical difference between women at group of 22 - 34 years and group of 35 -49 years (P >0. 05). However, those in women at group of 22 -34 years and 35 -49 years showed statistical difference when compared with women at group of more than 50 years ( P < 0. 05 ). When compared with women at group of 22 - 34 years, the incidence of posterior and anterior vaginal wall protrusion were increased ( OR = 1. 713, 3. 765). (4) Menopause status was associated with severities of all kinds of descent ( P < 0. 05 ) and presence of posterior vaginal protrusion ( OR = 3. 354 ). Conclusions Mild anterior and posterior vaginal descent by POP-Q were common among women in China. The risk of anterior vaginal descent is relatively higher than posterior vaginal descent. However, most of the women with descent are asymptomatic and need no treatment. The most important factors associated with the severity and detectable ratio of descent is parity and age.

Two patients with coexistence of thyroid disease and suspected Gitelman's syndrome underwent SLC12A3 gene analysis. The results confirmed that both patients were compound heterozygotes of SLC12A3 gene mutation. Three novel variants of SLC12A3 were found in this study. This report suggests that Gitelman's syndrome may coexist with other disorders associated with hypokalemia, such as Graves' disease.
