ABSTRACT
Objective:To investigate the changes and clinical significance of blood coagulation function and von Willebrand factor antigen (vWF:Ag) in patients with HELLP syndrome (hemolysis, elevated liver function, low platelet count).Methods:The clotting data of patients with severe preeclampsia and HELLP syndrome (observation group) admitted to the department of critical care medicine of the Fifth Center Hospital in Tianjin from May 2015 to December 2019 were retrospectively analyzed, and normal late pregnancy women with the same period were enrolled as the control group. The coagulation indexes such as prothrombin time (PT), activated partial thrombin time (APTT), antithrombin (AT), fibrinogen (Fib), D-dimer and plasma vWF:Ag level were compared between the two groups, and among patients with HELLP syndrome with different disease degree.Results:① Sixty-five patients with HELLP syndrome and 65 normal pregnant women with third trimester were included. Both groups were women of childbearing age, and there were no significant difference in the baseline data. ② The levels of Fib, D-dimer in both groups increased, but they were significantly higher in the observation group than those in the control group [Fib (g/L): 4.94 (4.76, 5.85) vs. 3.58 (2.97, 4.14), D-dimer (mg/L): 3.34 (2.55, 4.32) vs. 1.72 (1.29, 2.08), both P < 0.05], the AT was obviously reduced [62.00 (49.00, 73.00)% vs. 97.50 (90.75, 107.00)%, P < 0.01], and both PT and APTT were in the normal reference range in the two groups. In addition, the plasma vWF:Ag level in the observation group was significantly higher than that in the control group [516.50 (467.20, 563.00)% vs. 246.45 (189.95, 274.10)%, P < 0.01]. ③ According to thrombocytopenia, among the 65 patients with HELLP syndrome, 26 cases were mild [platelet count (PLT) > 100×10 9/L], 22 cases were moderate [PLT (50-100)×10 9/L], and 17 cases were severe (PLT < 50×10 9/L). With the aggravation of the disease, the D-dimer, Fib, vWF:Ag levels in the mild, moderate, severe patients significantly increased, while the AT level significantly decreased, and there was statistically significant difference between the two groups [D-dimer (mg/L): 2.63 (2.60, 2.73), 3.15 (2.55, 3.73), 3.84 (3.52, 4.23); Fib (g/L): 4.23 (4.06, 4.47), 4.72 (4.34, 5.04), 5.43 (5.14, 5.76); vWF:Ag: 465.20 (437.20, 495.40)%, 500.10 (472.40, 534.50)%, 543.50 (521.30, 563.00)%; AT: 67.50 (61.60, 78.00)%, 63.70 (53.30, 70.40)%, 54.40 (44.00, 61.20)%; all P < 0.05]. Conclusion:Patients with HELLP syndrome may show hypercoagulability and excessive expression of peripheral blood vWF:Ag level, which can induce platelet aggregation, leading to thrombocytopenia and thrombotic microangiopathy, and the clinicians should pay attention to that.

ABSTRACT
Objective To investigate the feasibility of clinical staging and standardization of therapy for patients with gallstones.Methods The clinical data of 326 cases of gallstones treated in our hospital from January 2012 to December 2013 were collected.Appropriate surgical procedures were selected based on preoperative staging (stags Ⅰ -Ⅳ)that was conducted according to the degree of pathological damage in the gallbladder.Clinical efficacy was observed for assessment.Results Among 57 patients categorized as stage I,53 cases received chole-dochoscopy by small incision for preservation of the gallbladder,including 3 cases converted to cholecystostomy and 1 case of recurrent gall-stones one year later;laparoscopic cholecystectomy was performed in the remaining 4 cases.A total of 152 patients were categorized as stageⅡ:122 cases received laparoscopic cholecystectomy,of which 2 cases were converted to open cholecystectomy,2 cases developed bile leak-age,and none suffered serious complication of bile duct injury;open cholecystectomy was performed in the other 30 cases in category II,2 of which had fat liquefaction at the incision,but complications of bile leakage and bile duct injury were not observed.There were 87 patients with stage Ⅲ disease:among 50 cases who received open cholecystectomy,3 cases developed fat liquefaction at the incision,but no bile leakage and bile duct injury were observed;in the remaining 37 cases who received open choledochoscope -assisted cholecystostomy,7 ca-ses developed fat liquefaction at the incision,and 10 cases eventually underwent open cholecystectomy three months after the operation due to cystic duct closure and opening abnormality detected by angiography.Thirty patients with stage IV disease underwent cholecystectomy and choledocholithotomy,of which 2 cases developed fat liquefaction at the incision,but no bile leakage and bile duct injury were observed.All 326 patients were cured without mortality.The incidence of adverse events was 6.75%.Conclusion The standardization of therapy for pa-tients with gallstones is an effective approach to ensure the clinical efficacy and to avoid or reduce postoperative complications.It should be promoted in clinical settings.
ABSTRACT
Purpose To investigate the clinicopathologic characteristics, differential diagnosis, treatment and prognosis of differentia-ted-type vulvar intraepithelial neoplasia ( dVIN) . Methods Clinicopathologic findings and immunophenotypes of 6 cases diagnosed as“dVIN” were retrospectively analyzed, and the relevant literatures were also reviewed. Results 6 patients were all female ranged 53~80 years old with mean age of 62 years old. Clinical aspects included leukoplakia vulvar, pruitis, irritation, pain, ulcer and so on. The histopathological features were hyperplasia of basal and parabasal layer with elongation and anastomosing reteridges. Cells were marked atypia with obvious nucleoli, atypical mitosis, and dyskeratosis. In the middle and surface layer, cells were well differentiated with pronounced intercellular bridges, and eosinophilic cytoplasm, hyperkeratosis and parakeratosis. Oedema and band of infiltration of chronic inflammatory cells of subepidermal could been seen. Immuohistochemistry showed the expression rates of p53 and p16 in totally 6 cases were 83. 3% (5/6), 0 (0/6), respectively. The Ki-67 index was more than 90% in basal and parabasal cells. Four patients were followed up ( mean follow-up 17 months, range 6~36 months) , one patient died at 9 months later after surgery, another patient recurred at 6 months later after surgery, both of the 2 cases were all with invasive lesions after resection, and the rest two cases had no recur in 18 months and 36 months after surgery, respectively. Conclusion dVIN is a high grade squamous intraepithelial lesions of vulvar with low incidence rate, but had more risk of progression. p53, p16 and Ki-67 stain were useful in the diagnosis of dVIN.
ABSTRACT
Purpose To investigate the expression and clinical significance of the cell cycle inhibitors p16 protein and specific recogni-tion of viral replication intermediate TLR3 in the cervical intraepithelial neoplasia ( CIN) and cervical invasive carcinoma. Methods Immunohistochemical stain was used to detect the expressions of p16 and TLR3 in 19 cases of normal cervical epithelium ( NCE) , 62 cases of CIN, and 17 cases of cervical squamous cell carcinoma (SCC). Results The positive rates of p16 protein were 0, 72. 5%and 100% in NCE, CIN and SCC respectively in which the difference among those groups were statistically significant ( P<0. 01 ) . Similarly, the positive rates of TLR3 protein were 26. 3%, 87% and 100% in NCE, CIN and SCC respectively and the difference a-mong those groups was significant (P<0. 01). Furthermore, there was a significant and positive correlation between the expression of p16 and TLR3 (rs =0. 538, P<0. 01). Conclusion Increased expression is observed in CIN and SCC compared with NCE and the expression of p16 and TLR3 is associated with level of CIN. Those could provide certain experiment basis for the pathologica diagnosis of early cervical cancer.
ABSTRACT
Objective To investigate the relationship between cholecystectomy and the subsequent occurrence of primary choledocholithiasis and to review the surgical treatment of primary choledocholithiasis.Methods The clinical data of 70 patients with forward common bile duct stones after cholecystectomy who were admitted to our hospital from January 2007 to December 2013 were retrospectively analyzed.Results All 70 patients underwent open surgery for removal of common bile duct stones,which were identified as bile pigment calculi.The postopera-tive complications included incisional wound infection (8 cases)and lung infection (5 cases),and no severe complications as biliary leak-age or hematobilia were observed.All patients fully recovered at the time of discharge.Eight cases of recurrent common bile duct stones were found and surgeries were performed 2.5 to 4 years after the recurrence.All patients were cured by choledocholithotomy,common bile duct transection,and Roux-en-Y hepaticojejunostomy.Conclusion Primary choledocholithiasis is an age-related disease,not a long-term complication of cholecystectomy.If no bile duct injury occurs during the cholecystectomy,the incidence rate of primary choledocholithiasis will not be increased.Surgical treatment is required for primary choledocholithiasis.For the cases of choledochectasia with the diameter of common bile duct greater than 2.5 cm or recurrent choledocholithiasis,the laparotomy with common bile duct transection and Roux-en-Y anastomosis is recommended.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinicopathologic characteristics, prognosis and histologic origin of the mucinous tumor of the peritoneum.</p><p><b>METHODS</b>According to 2010 WHO classification of tumours of the digestive system, 34 cases diagnosed as "pseudomyxoma peritonei (PMP) " were reevaluated and divided into low grade and high grade. Immunohistochemistry was applied to investigate the expression of SATB2 and the histologic origin of the mucinous tumor of the peritoneum, using antibodies against SATB2, CK7, CK20 and CDX-2. The relationship between clinicopathologic characteristics and prognosis of the low grade and high grade tumors were analyzed.</p><p><b>RESULTS</b>Twenty five patients had low grade mucinous tumors (two of them were no cell type), nine patients had high grade mucinous tumors. There was no significant difference between low grade and high grade mucinous tumors in age, sex, recurrence and organs involvement (P>0.05). Thirty patients were followed up, the overall survival rates of patients with low grade and high grade mucinous tumors were 13/21 (61.9%) and 3/9, respectively. The median survival time was 74 and 24 months in low and high grade patients, and the difference was statistically significant (P=0.002).Immunohistochemistry showed the expression rates of CDX-2, CK20, and CK7 in totally 32 cases (excluding 2 cases of no cell type) were 30/32(93.8%), 31/32 (96.9%), and 3/16, respectively; the expression rates of CDX-2, CK20, and CK7 in 16 cases with distinct primary site were 15, 16, and 1, respectively; fifteen of 16 cases of tumors of unknown primary site were positive for CDX-2 and CK20, two of the them were positive for CK7. There was no difference in the expression of CDX-2, CK20 and CK7 between tumors with distinct primary site and tumors with unknown primary site (P>0.05). The expression rate of SATB2 in the cases was 56.3% (18/32), excluding 2 cases of no cell type. There was no significant difference between low grade and high grade tumors in the expression of SATB2 [15/23(65.2%) vs 3/9, P=0.102], also SATB2 was not related to the prognosis of the tumor (P=0.786).</p><p><b>CONCLUSION</b>The prognosis of the mucinous tumor of the peritoneum was significantly different between low grade and high grade according to WHO 2010 classification, and most mucinous tumor of the peritoneum originated from the appendix.</p>

ABSTRACT
Objective To analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed.Imaging findings of CT were reviewed and compared with surgical pathology. Results Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 ease. The lesion was classified as tumour type (8 cases)and infiltration type (1 case). In tumour type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan,the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast baeilli.
ABSTRACT
45 strains of Lactobacillus were isolated from 17 samples of traditional fermented milk in Gobi region of Mongolia. Based on morphological, physiological, biochemistry test and 16S rDNA sequencing analysis, identified as 31 strains of Lactobacillus fermentum(L. fermentum), 12 strains of L. helveticus, one strain of L. plantarum and one strain of L. casei. Survival rate of IMAU20085 is 81.44% in the screening experiment of resistance to the artificial gastric juice (pH 3.0). The isolation and identification of these strains and the screening of high acid-tolerant strains have important meaning to the preservation and exploitation of probiotic resource.
ABSTRACT
Objective:To study the anti-inflammatory effect of immune milk. Method:Twenty four strains of pathogenic bacteria (including 12 strains of pathogenic E.coli, 8 strains of Salmonella, 3 strains of Shigella and 1 strain of Yersinia enterocolitica) originated from human intestinal tract were selected as antigens, and dairy cows were immunized. Results:Vaccination could not increase the concentration of IgG in the immune milk, but significantly highten the specificity of milk antibodies. The antibody titers against 24 pathogenic bacteria in immune milk was 128, 64 folds of control regular milk. Conclusion:Feeding of immune milk could inhibit edema of rat footpad induced by carrageenin and formaldehyde and the formation of acestoma of mice caused by cotton embedded hypophloedally. Meanwhile, the PGE2 level in inflammatory footpad of rat fed with immune milk was remarkably lower than that of rat fed with regular milk. These results indicate that immune milk has anti-inflammatory property.
