ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.</p><p><b>METHODS</b>Totally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.</p><p><b>RESULTS</b>The total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.</p><p><b>CONCLUSION</b>YHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.</p>

Pancreaticoduodenectomy (PD) is the most effective treatment for patients with pancreatic head or periampullary lesions. Two major strategies exist: pylorus-preserving pancreaticoduodenectomy (PPPD) and pylorus-resecting pancreaticoduodenectomy (PRPD). However, it is yet unclear regarding the morbidity after PPPD and PRPD. This study analyzed the morbidity after PPPD and PRPD to determine the optimal surgical treatment of masses in the pancreatic head or periampullary region. A systematic search of databases identifying randomized controlled trials (RCTs) from the Cochrane Library, PubMed, EMBASE and Web of Science was performed. Outcome was compared by postoperative morbidity including overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding, biliary leakage, ascites and delayed gastric emptying (DGE) rate between PPPD and PRPD. The DGE rate in the PRPD subgroups (conventional PD [CPD] and subtotal stomach-preserving PD [SSPPD], respectively) was also analyzed. The results showed that 9 RCTs including 722 participants were included for meta-analysis. Among these RCTs, 7 manuscripts described PRPD as CPD, and 2 manuscripts described PRPD as SSPPD. There were no significant differences in the overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding, or biliary leakage between PPPD and PRPD. There was a lower rate of DGE with PRPD than that with PPPD (RR=2.15, P=0.03, 95% CI, 1.09-4.23). Further subgroup analysis indicated a comparable DGE rate for the CPD but a lower DGE rate for the SSPPD group than the PPPD group. However, the result did not indicate any difference between CPD and SSPPD regarding the DGE rate (P=0.92). It is suggested that PPPD is comparable to PRPD in overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding and biliary leakage. The current data are not sufficient to draw a conclusion regarding which surgical procedure is associated with a lower postoperative DGE rate. Our conclusions were limited by the available data. Further evaluations of RCTs are needed.
