ObjectiveTo examine the effect of Xuebijing Injection on the number of T lymphocytes and Toll-like receptors as adjuvant therapy of severe abdominal infections.MethodsA total of 78 patients with severe abdominal infection who were hospitalized in the intensive care unit were divided into control group and treatment group. The patients in control group received conventional therapy alone, while the patients in treatment group received Xuebijing Injection (50 mL twice daily for 2 weeks) in addition to conventional therapy. Blood sample was drawn before and after 2-week treatment to determine T lymphocytes. The peripheral blood mononuclear cells were separated to determine the expression of Toll-like receptors (TLR) 2 and TLR4. The Acute Physiology and Chronic Health Evaluation (APACHE) II score and gastrointestinal function score were recorded before and after treatment.ResultsThe levels of CD3+, CD4+ and CD4+/CD8+ of peripheral blood in the Xuebijing-treated patients were signiifcantly higher than those in control group (P<0.01), but the levels of CD8+ was signiifcantly lower than that in control group (P<0.01). The levels of TLR2 and TLR4 mRNA of the peripheral blood mononuclear cells in the treatment group were signiifcantly lower than those in control group (P<0.01). The APACHE II score and gastrointestinal function score in treatment group were signiifcantly lower than those in control group (P<0.01).ConclusionXuebijing Injection as adjuvant therapy of severe abdominal infection can improve the number of T lymphocytes, and reduce the expression of Toll-like receptors.

Objective To investigate the effects of different means of liquid resuscitation on microcirculation in rats with hemorrhagic shock. Method A model of rats with hemorrhagic shock was established in 40 Wistar rats. The rats were randomly divided into 4 groups according on different means of liquid resuscitation, and killed 24 hours after the examination, group A: without liquid resuscitation; group B: low-molecular-weight-40; group C: 7.5% hypertonic saline,group D:low-molecular-weight-40 + hyperonic saline. As well as the microcirculation in kidney was observed using electron microscope. Results In group without resuscitation, the microcirculation in kidney damaged severely; While in group with hypertonic or low molecule dextran alone, there was harm with dif-ferent degrees, and the microcirculation in kidney was nearly perfect in group with both hypertonic and low molecule dextran alone. Conclusions Different means of liquid resuscitation may infect the microcirculation in kidney, which with both hypertonic and low molecule dextran can protect the microcirculation in kidney.

OBJECTIVETo investigate the serological and genetic characteristics of an individual with B(A) phenotype of the ABO subtype and his family members.
METHODSSerological assaying was carried out to characterize the erythrocyte phenotype of the discrepant samples. Exons 6 and 7 of the ABO gene were amplified with PCR and subjected to direct sequencing. Exon 7 of the ABO gene was also subjected to single strand sequencing.
RESULTSThe serological results of two samples from the family were prelimilarily typed as AwB and genotyped as B(A)04/O1 by sequence-specific primer PCR (PCR-SSP). Direct and single strand sequencing confirmed that the three samples all carried a B(A)04 allele and had a nt640A>G mutation in exon 7 of the ABO gene.
CONCLUSIONThe nt640A>G mutation of the B allele has resulted in an amino acid substitution (Met214Val), which probably underlies the B(A)04 subtype. Blood samples with serological typing difficulty may be resolved by pedigree analysis using molecular methods such as PCR-SSP and DNA sequencing.

Objective To investigate the application value of the preoperative progressive pneumoperitoneum (PPP) in parastomal hernia repair.Methods The retrospective cross-sectional study was conducted.The clinical data of 28 patients who underwent parastomal hernia repair using PPP in the Sixth Affiliated Hospital of Sun Yat-sen University from December 2014 to February 2017 were collected.Patients received abdominal computed tomography (CT) scan after admission,and volumes of the hernia sac and abdominal cavity and (volume of the hernia sac / total volume of the abdominal cavity)× 100.0% were respectively calculated.Open or laparoscopic parastomal hernia repair was selected based on the effects of artificial pneumoperitoneum.Observation indicators:(1) PPP situations:① completion;② changes of volumes of the hernia sac and abdominal cavity before and after PPP;③ adhesion and retraction of parastomal hernia contents after PPP;(2) surgical and postoperative recovery situations;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative long-term complications and recurrence of parastomal hernia up to May 2017.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (range).Repeated measurement data were evaluated with the repeated measures ANOVA.Results (1) PPP situations:① completion:28 patients received successful ultrasound-guided indwelling catcher.Twenty-four patients completed PPP,with a completion rate of 85.7% (24/28) and an air injection volume of (3 995±531) mL,and 4 stopped PPP.Eighteen patients had varying degrees of abdominal pain,abdominal distension and scapular pain,including 17 with tolerance and 1 with disappearing of symptoms at day 6.Of 5 patients with shortness of breath,3 were improved or well tolerated through breathing exercises,and symptoms of 2 disappeared at day 7 and 9.Three patients had mild subcutaneous emphysema.The arterial CO2 tension of 1 patient was high and then returned to normal at day 7.Some patients had simultaneously multiple adverse reactions.② Changes of volumes of the hernia sac and abdominal cavity before and after PPP:volumes of the hernia sac before and after PPP were (699± 231) mL and (993 ± 332) mL,with a statistically significant difference (F=129.29,P<0.05),and increasing volume of the hernia sac was (294± 167) mL,with an increasing rate of 43%±15%.Volumes of the abdominal cavity before and after PPP were (6 520±745)mL and (9 196± 909) mL,with a statistically significant difference (F=429.42,P<0.05),and increasing volume of the abdominal cavity was (2 715±709)mL,with an increasing rate of 42%± 12%.(Volume of the hernia sac / total volume of the abdominal cavity) × 100.0% before and after PPP were 9.6% ± 2.7% (less than or equal to 10.0% in 20 patients,more than 10.0% and less than or equal to 15.0% in 6 patients,and more than 15.0% in 2 patients) and 9.7%± 2.8%,with no statistically significant difference (F =0.44,P>0.05).③ Adhesion and retraction of parastomal hernia contents after PPP:results of abdominal CT showed anterior abdominal bulging,abdominal contents prostrated at the base of the abdominal cavity due to gravity,and gas was full of gaps.Abdominal adhesion signs:adhesions of banded fibrous connective tissue established a connection between the base of the abdominal cavity and anterior abdominal wall,and intestinal canals were found inside the adhesions.Parastomal hernia contents of 28 patients had varying degrees of retraction to abdominal cavity,including 9 with complete retraction,13 with a great amount of retraction (retraction volume >50%) and 6 with a small amount of retraction (retraction volume <50%).Four patients were accompanied by incomplete stoma obstruction,and then obstruction disappeared or relieved after PPP.(2) Surgical and postoperative recovery situations:all the 28 patients underwent successful operations,without intestinal canal injury.Three patients received open parastomal hernia repair,including 2 receiving preperitoneal mesh repair using 8 layers Biodesign meshes (deep venous catheter for local drainage was placed and then removed at postoperative day 2 and 3) and 1 receiving Sugarbaker surgery using PCOPM mesh (peritoneal drainage-tube was placed and then removed at postoperative day 2).Other 25 patients received laparoscopic parastomal hernia repair and Sugarbaker surgery using PCOPM and Sepramesh meshes (no drainage-tube was placed).Bladder pressure of 28 patients at postoperative day 3 was (13±6)cmH2O (1 cmH2O =0.098 kPa),without an abnormal high pressure.Nine patients with postoperative complications were improved by conservative treatment,including 3 with seroma,3 with delayed stoma defecation or incomplete intestinal obstruction,2 with pulmonary infection and 1 with urinary tract infection.There were no occurrences of abdominal compartment syndrome,cardiac failure,lung failure,renal failure,other severe complications and perioperative death.Duration of postoperative hospital stay was (7.2± 1.5) days.(3) Follow-up situations:25 of 28 patients were followed up for 3-25 months,with a median time of 11 months.During follow-up,2 patients had chronic pain around the operation and a sense of discomfort and then were improved by symptomatic treatment,and 1 with parastomal hernia recurrence at postoperative month 6 after open preperitoneal mesh repair underwent again open preperitoneal mesh repair,without recurrence.There were no occurrence of tardive mesh infection and other longterm complications.Conclusion PPP in the treatment of parastomal hernia repair is safe and feasible.
