[Objective] To investigate the efficacy of Xiangsha Yangwei Wan (XYW) on the inhibition of chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms. [Methods] A randomized controlled trial (RCT) was carried out in 87 cases of maligant tumor confirmed by histopathological and cytological examination. All the cases were treated with chemotherapy regimen of adriamycin ( ADM) , adcarbazine ( DTIC) , platinum-based agents, irinotecan (CPT-11) and fluorouraeil (5-FU). Meanwhile, 41 cases in group A were also treated with dexamethason and 5-HT3 receptor antagonist as an essential anti-emesis and with XYW to regulate gastrointestinal function; other 46 cases in group B were given dexamethason and 5-HT3 receptor antagonist only. Seven days after treatment, incidences of chemical gastritis and upper gastrointestinal symptoms were observed and compared between the two groups. [Results] Seven days after chemotherapy, upper gastrointestinal symptoms and signs were relieved in 95.1% (39/41) of the patients of group A and in 76.1 % (35/46) of group B; the occurring rate of chemical gastritis with symptoms was 2.4% (1/41) in group A and 19.6% (9/46) in group B, the differences being significant statistically between the two groups( P - 0.0122) . [ Conclusion ] XYW has an inhibitory effect on chemotherapy-induced chemical gastritis and upper gastrointestinal symptoms.

ObjectiveTo study the molecular genetic mechanism of para-bombay phenotype in two individuals.MethodsThe proband was a female.When the proband donated blood,because the forward blood group wasn't coincident with her reverse blood group,the blood and saliva specimen from proband and her family members were sent to Guangzhou Blood Center for further identification.Routine serological techniques were used to determine proband's and her family members' blood group and ABH antigen in saliva.The coding regions of FUT1 and FUT2 gene,exon 6 and exon 7 of ABO gene were amplified by polymerase chain reaction using proband's and her family members' genomic DNA.All amplified products were analyzed after being directly sequenced.The two-base deletion regions of FUT1 gene were certified by cloning and haplotype sequencing.Results Proband's and her little brother's blood group were identified as para-bombay while other family members' blood group were normal.Two-base deletion heterozygous mutations of FUT1 gene were found in proband and her brother,AG deletion at position 547-552 and TT deletion at position 880-882,which caused a reading frame shift and a premature stop eodon.Meanwhile,880-882del TT heterozygous mutation was found in proband's grandfather and her father and 547-552del AG heterozygous mutation was found in proband's mother and her little sister.ResultsOf cloning and haplotype sequencing certified that these two-base deletion mutations occurred at 547-548 and 881-882 position respectively.Three new mutations were found in FUT2 gene,390C > T,418A > T and 749G > A,which could cause the change of amino acid at position 140Ile > Phe and 250Arg > Gln.Conclusions Two-base deletion heterozygous mutations in different positions in FUT1 gene were found in 2 individuals,which maybe the molecular genetic mechanism of para-bombay phenotype.Heterozygous deletion mutation in one-strand DNA wouldn't change the ABO blood group.Three new mutations were also found in FUT2 gene.( Chin J Lab Med,2012,35:815-819)

Objective:To study the clinical features of the "migration birds" population in Hainan Province in winter presenting with acute cholecystitis.Methods:Patients who were diagnosed to suffer from acute cholecystitis in the winter months from November to February of the following year of 2017, 2018 and 2019 and admitted in Hainan Hospital of Chinese PLA General Hospital were included in this study. The "migration birds" patients who arrived in Hainan Province in less than 30 days were defined as the short-term group ( n=49), 30-89 days as the mid-term group ( n=24), more than 90 days as the long-term group ( n=48). The general information, associated medical diseases, clinical presentations, interventional strategies and in-hospital outcomes were compared, and further analyze the clinical characteristics of patients with purulent cholecystitis and non-purulent cholecystitis in the short-term group. Results:Of 120 patients, there were 49 patients in the short-term group (29 males and 20 females with an average age of 65.18±15.02 years), 24 patients in the mid-term group (13 males and 11 females with an average age of 66.21±11.93 years), and 48 patients in the long-term group (30 males and 18 females with an average of 60.73±12.54 years). The general information, interventional strategies and in-hospital outcomes were similar among the three groups. When compared with patients in the long-term group, patients in the short-term group had higher incidences of hypertension [20.83% (10/48) vs 48.98% (24/49)] and diabetes [10.42% (5/48) vs 30.61% (15/49)]. The gallbladder wall in the short-term group was significantly thicker than that in the long-term group [0.60(0.40, 0.70) cm vs 0.50(0.30, 0.60) cm, P<0.017]. The proportion of purulent cholecystitis in the short-term group was significantly higher than that in the long-term group [48.15% (13/27) vs 17.24% (5/29) , P<0.017] . In the short-term group, the incidences of silt-like stones of purulent cholecystitis [38.46% (5/13) vs 14.29% (2/14)], gallbladder perforation [30.77% (4/13) vs 0], gallbladder gangrene [53.85% (7/13) vs 7.14% (1/14)], perigallbladder effusion [76.92% (10/13) vs 14.29% (2/14)], abdominal effusion [46.15% (6/13) vs 7.14% (1/14)] were significantly higher than that of patients with non-purulent cholecystitis, (all P<0.05). Conclusion:Patients presenting with acute cholecystitis after arrival in Hainan in the short term had more severe inflammation with complications of suppuration, perforation and gangrene. Patients with hypertension and diabetes were the high risk group of patients presenting with acute cholecystitis after short-term arrival in Hainan.

Objective The primary aim of this study was to examine the proportion and natural history of Helicobacter pylori (Hp) negative bleeding peptic ulcers. Methods The study was designed as a multiple-center, case-control study conducted in 14 endoscopy centers in China from April 2006 to March 2007. Each center was expected to recruit 30 peptic ulcer patients with bleeding ( PUB group) and 30 without (PU group). All screened patients with upper gastrointestinal bleeding received endoscopy within 24 hours of admission. Biopsy specimens were taken from the antrum to determine Hp infection by rapid urease test and pathology. Patients with negative Hp infection at first examination were asked to receive urease breathe test (UBT) one month later. Results A total of 617 patients were enrolled with 263 in PUB group and 354 in PU group. There is no significant difference in demographic characters between 2 groups ( P >0. 05). The rate of Hp infection in PUB group ( 161/263, 61.2% ) was significantly lower than that in PUgroup (311/354, 87. 9%, P <0. 001 ). The incidence of complex ulcer in Hp positive PUB patients was 7.5% ( 12/161 ), which is significantly higher than that in Hp negative PUB patients ( 1/102, 1.0% , P =0. 018). In PUB group, no significant differences were found between Hp positive and negative patients in regarding of age, sex, rates of haematemesis, duodenal ulcer and gastric ulcer, and size of ulcer ( P >0. 05 ). Among 102 Hp negative cases in PUB, no positive case was found in UBT one month later. Conclusion We have demonstrated a rise in the incidence of Hp negative bleeding ulcers in China. The idiopathic ulcer was not rare, and might have a higher tendency to cause bleed.
