Objective:To explore the diagnostic value of ultrasound combined with tumor markers carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) for peritoneal metastasis of gastrointestinal adenocarcinoma.Methods:A retrospective case series study was conducted. A total of 140 patients with gastrointestinal adenocarcinoma who were admitted to Shanxi Province Cancer Hospital from August 2021 to January 2023 were collected. Preoperative diagnosis of peritoneal metastasis was performed using tumor markers CEA and CA199 (tumor marker method) and ultrasound combined with CEA and CA199 (combined method). Using postoperative pathological results as the gold standard, the detection rate and diagnostic efficacy of the two methods for peritoneal metastasis in patients were compared.Results:Among 140 patients, there were 78 males and 62 females; the age was (59±5) years old; there were 40 cases of gastric cancer and 100 cases of colorectal cancer; pathological staging: 4 cases in stage Ⅰ, 36 cases in stage Ⅱ, 52 cases in stage Ⅲ, and 48 cases in stage Ⅳ. All patients underwent radical resection surgery, and postoperative pathological results showed that 32 cases (22.86%) had peritoneal metastasis. The detection rate of combined method for peritoneal metastasis of gastrointestinal adenocarcinoma was higher than that of tumor marker method [96.88% (31/32) vs. 78.13% (25/32)], but the difference was not statistically significant ( χ2 = 5.14, P = 0.059). The sensitivity of tumor marker method for diagnosing peritoneal metastasis of gastrointestinal adenocarcinoma was 64.00%, the specificity was 86.09%, the positive predictive value was 50.00%, the negative predictive value was 91.67%, the Kappa value was 0.379, and the area under the curve (AUC) was 0.793. The sensitivity of combined method for diagnosing peritoneal metastasis of gastrointestinal adenocarcinoma was 77.42%, the specificity was 92.66%, the positive predictive value was 75.00%, the negative predictive value was 93.52%, the Kappa value was 0.905, and the AUC was 0.985. The sensitivity and positive predictive value of combined method for diagnosing peritoneal metastasis of gastrointestinal adenocarcinoma were higher than those of tumor marker method, and the differences were statistically significant ( χ2 values were 4.06 and 13.33, both P < 0.05). Conclusions:Ultrasound combined with serum tumor markers CEA and CA199 has high diagnostic value for peritoneal metastasis of gastrointestinal adenocarcinoma.

Objective:To establish an HPLC method for the determination gensenoside Rg1 , Rb1 and notogensenoside R1 in Sanqi Jiegu pills and to investigate the stability of saponins in the granulation process. Methods:The separation was performes on a COSMO-SIL 5 C18 MS-II(250 mm × 4. 6 mm,5μm)column with gradient elution using water and acetonitrile as the mobile phase, the flow rate was 1. 0 ml·min-1 , the detection wavelength was 203nm, the column temperature was 30℃, and the injection volume was 10 μl. The content change of triterpene saponins in Sanqi Jiegu pills prepared by the granulation process at different drying temperature was al-so investigated. Results:The linearity of notogenoside R1 , gensenoside Rg1 and gensenoside Rb1 was good within the range of 0. 211 8-2.648 0 μg·ml-1(r=0.999 7),0.566 1-7.076 0 μg·ml-1(r=0.999 7) and 0.317 2-3.964 5μg·ml-1(r=0.999 7) with the average recovery of 98. 2%(RSD=0. 82%,n=6), 98. 1%(RSD=0. 72%,n=6) and 98. 1%(RSD=0. 59%,n=6),respectively. The content of saponins in Saqi Jiegu pills was decreased obviously with the increase of the drying temperature. Conclusion:The meth-od is simple, quick and reliable, and can be applied in the quality control of Sanqi Jiegu pills. It is recommended that the drying tem-perature in the granulation process should be controlled below 60℃.

Objective To evaluate the clinical value of color Doppler ultrasound-guided percutaneous transhepatic cholangiol drainage(PTCD) for treating obstructive jaundice. Methods 248 cases of PTCD were performed in 224 patients under the guidance of color Doppler ultrasound. 118 PTCD cases were carried out passing through the inferior segmental biliary duet of Left laterallobe (Left drainage mode). Right lobe drainage mode (right drainage mode)was conducted in 130 patients. Left plus right lobe drainage mode in 16 patients. Results The total success rate was 99.59 %(247/248), and the success rate of the firs time PTCD was 92.33 %(229/248). The success rate of left drainage mode was significantly higher than righl lobe drainage (96.61% vs 88.46 %, P ＜0.05). Conclusion The technique of color Doppler ultrasound-guided PTCD is an efficient method in obstructive jaundice therapy, with the advantages of safety, convenience, minimal invasion, and higher success rate.

OBJECTIVETo study the pathogenic effect of hepatitis G virus (HGV) infection on hepatic failure.

METHODSUsing the RT-PCR and EIA techniques to detect HGV RNA and anti-HGV in sera of hepatic failure patients and compare them with their liver function and mortality rates.

RESULTSThere was no significant difference about the positive rates of HGV among acute hepatic failure, subacute hepatic failure and chronic hepatic failure groups (X(2)=2.54, P>0.05). The level of ALT in HGV-positive group was slightly lower than that in HGV-negative group. The concentration of bilirubin and globulin was higher in HGV-positive group than HGV-negative group, and the concentration of albumin in HGV-positive group was significantly lower than that in HGV-negative group (t=2.59, P<0.05). The mortality rate in HGV-positive group was significantly lower than that in HGV-negative group (X(2)=4.68, 0.01

CONCLUSIONSThe virulence of HGV is mild, and the HGV infection does not aggravate hepatic failure.
