OBJECTIVETo explore the pathologic mechanism of blood-stasis tongue figure (BSTF) formation in patients with primary dysmenorrhea.

METHODSBlood levels of platelet activating factor (PAF) and acetyl hydrolase of PAF (PAF-AH) in 41 patients with primary dysmenorrhea and 20 healthy subjects were detected by enzyme linked immunosorbent assay (ELISA).

RESULTSThe level of PAF in the 22 patients with BSTF was 252. 214 +/- 37. 568 ng/L, which was higher than that in patients without BSTF (19 patients, 212.348 +/- 22.794 ng/L) and healthy subjects (182.126 +/- 18.306 ng/L) respectively, while level of PAF-AH showed an opposite sequence in them, i.e., 3.090 +/- 1.483, 5.382 +/- 1.873, and 5.607 +/- 2.073 ng/L, respectively (P < 0.05). Patients without BSTF showed only a higher level of PAF when compared with that in healthy subjects (P < 0.05). No significant difference in PAF or PAF-AH levels was shown among patients with BDTF of different Chinese medical syndrome types (P > 0.05).

CONCLUSIONPAF level obviously increased and PAF-AH level obviously decreased in primary dysmenorrhea patients of BSTF, suggesting that the imbalance of PAF and PAF-AH was correlated with the pathologic mechanism of the BSTF formation in primary dysmenorrhea patients.

Objective To investigate the clinical features of the enterovirus 71 ( EV71 ) infection complicated with pulmonary edema or pulmonary hemorrhage as a fulminant and often fatal illness.Methods The medical records of three cases with EV71 infection were retrospectively reviewed for clinical manifestations, laboratory data, medications, and outcome.Results All the cases were infants and died of the infection. These infants had no skin or mucosal lesions, however, they had sudden onset of cyanosis and tachypnea 1 to 2 days after the onset of the febrile disease with vomiting. All these 3 cases were misdiagnosed and were treated for shock on admission. Pulmonary hemorrhage was not considered in any of the cases on admission. All the cases received tracheal intubation when foamy secretions were discharged from the mouth and nose of the patients and notable cyanosis occurred. After intubation, pink foamy fluid flew out from the endotracheal tube in all the 3 cases. The patients had hyperglycemia and limb weakness, two had tachycardia, and hypertension was found in one case. Chest X-ray showed bilateral or unilateral widespread air space opacity, but the cardiac size and shape were normal. All the patients had leukocytosis. Enterovirus 71 infection was confirmed by detection of specific nucleic acid sequences of the virus from throat swab and tracheal secretions samples and in one case in cerebrospinal fluid.Conclusions Pulmonary edema or pulmonary hemorrhage occurred in the 3 cases with EV71 infection. The initial presentation was nonspecific with fever and vomiting, and sudden appearance of cyanosis, tachypnea, tachycardia, hypertension or hypotension, limb weakness, which may suggest pulmonary edema or hemorrhage. Excessive fluid resuscitation may deteriorate the illness, on the contrary, fluid restriction and inotropic agents, and early intubation with positive pressure mechanical ventilation may be the proper treatment.

Objective To investigate the clinical characteristics,diagnosis,treatment and prognosis of human swine streptococcosis occurred in some areas of Jiangsu Province from late summer to autumn since 1998.Methods The epidemiologic and clinical features of 42 cases were collected and analyzed.The bio- chemical features of strains isolated from patient's blood or cerebrospinal fluid(CSF) were tested,and the homogeneity were compared among 15 Streptococcus suisⅡ.Results All patients had acute infection toxe- mic symptoms such as chill,fever,headache and malaise etc.Toxic shock syndrome or meningitis syndrome were the major clinical manifestations.Forty two cases of human swine streptococosis were classified into 3 types:the rates of general,shock and meningitis type were 7.1% (3/42),38.1% (16/42) and 54.7%(23/42),respectively.Ten patients were died of shock type,32 were cured.Strain isolated from patients was identified as Streptococcus suisⅡby API-Strep,the biochemical reactional code was 0641473,and appraised result was 99.9%.There was highly homogeneity in the strains of Streptococcus suisⅡisolated from patients and sick pigs identified by genomic fingerprinting.Com- bined therapy of large doses of penicillin G and ceftriaxone was effective in these patients.Conclusions Human swine streptococosis is zoonosis caused by Streptococcus suisⅡand the clinical manifesta- tions are variable.In the cases of shock type,the onset of disease is stormy and the fatality rate is very high.While the prognosis of general and meningitis type is good and the majority of the cases are cured by effective antibiotic therapy.

OBJECTIVETo investigate the changes in plasma levels of vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1 (SDF-1) and in peripheral CD34(+) cells in patients with acute myocardial infarction (AMI), and explore their role in AMI.

METHODSEnzyme-linked immunoassay (ELISA) was employed for measuring the levels of VEGF and SDF-1 in AMI patients on days 1, 3, 7, 10, and 14 of onset and in normal control subjects. The absolute counts of CD34(+) in the peripheral blood were measured on days 1, 7, and 14 by flow cytometry in AMI patients, with their myocardial enzyme and troponin I detected and electrocardiography (ECG) and echocardiography (UCG) recorded.

RESULTSPeripheral CD34(+) cells obviously increased on day 7 after AMI onset (2.35-/+0.72/microl vs 1.48-/+0.49/micro, P<0.05). VEGF levels were significantly higher in AMI patients than in the control subjects, reaching the peak level and on day 14 (197.56-/+39.87 vs 53.79-/+18.12 pg/ml, P<0.01). SDF-1 level obviously decreased on day 1 after AMI onset (1683.12-/+224.79 vs 2178.67-/+265.34 pg/ml, P<0.01), followed by gradually increased to the control level. Obvious correlation was noted between the level of VEGF on day 7 and the peak level of peripheral CD34(+) cells, and the peak plasma VEGF level was obviously associated with the peak serum CK-MB and troponin I levels.

CONCLUSIONThe stem cells are mobilized into the peripheral blood in the event of AMI. Obviously increased VEGF level following AMI may persist for at least 2 weeks, whereas SDF-1 level undergoes temporary decrement after AMI. The dynamic changes of VEGF and SDF-1 can be related to the mobilization and homing of the stem cells to the injured myocardium.

OBJECTIVETo study the clinicopathologic features and biological behavior of spermatocytic seminoma.

METHODSA retrospective analysis of patients diagnosed as seminoma, spermatocytic seminoma between January 2003 and May 2011, was performed. Clinical data, HE stained section and immunohistochemical staining (SP method) were reviewed with follow-up.

RESULTSSixty-six cases of seminoma and 5 cases of spermatocytic seminoma were identified. The average age at the diagnosis of 5 cases of spermatocytic seminoma was 53 years, and no patient had a history of crytorchidism or germ cell tumor. All five patients had stage pT1 tumor. Immunohistochemical studies showed that spermatocytic seminoma was negative for CK, vimentin, OCT3/4, PLAP, and LCA, and PAS staining was also negative. All five patients were well after operation. In contrast, the average age at diagnosis of the 66 cases of seminoma was 37 years, in which 12% had a history of crytorchidism and 11% were in stage pT2 or the above. Immunohistochemical studies showed that seminoma was positive for OCT3/4, PLAP, and CD117. During the follow-up, 2 patients developed metastasis and 3 patients died of the disease.

CONCLUSIONSSpermatocytic seminoma is rare and appears to follow a benign clinical course Due to its favourable prognosis, further treatment is not necessary after orchidectomy. Accurate pathologic diagnosis is critical for patient management and for avoiding over-treatment.

OBJECTIVETo analyze operative and perioperative factors associated with hepatectomy in hepatolithiasis.

METHODS245 consecutive hepatolithiasis patients undergoing hepatectomy from January 1986 to December 2005 at Chinese People's Liberation Army General Hospital were investigated retrospectively according to medical documentation.

RESULTSHepatolithiasis accounted for 29.6% (245/827) in all benign liver diseases treated with hepatectomy during this time period. There were 88 cases in male and 157 cases in female, the average age was (46.9 +/- 11.3) years. Cases of right liver resection and hepatic segments resection were much more than that in 1963 - 1985. Blood transfusion during operation was given in 45.3% of cases. Complication incidence was 16.3%, with infection 3.3% and bile leakage 2.4%. Length of stay after operation was (15.7 +/- 9.2) days. Perioperative mortality rate was 0.4% (1/245).

CONCLUSIONSIndividualized hepatectomy is the important surgical treatment of hepatolithiasis. Hepatectomy can be performed safely with low mortality and low complication incidence, provided that it is carried out with optimized perioperative management and innovative surgical technique.
