OBJECTIVEThe efficacies of the selective 5-hydroxytryptamine3 (5-HT3) antagonists--ramosetron (0.3 mg) and granisetron (3 mg) in treating acute chemotherapy-induced digestive system dysunction were compared.
METHODSA total of 111 patients were enrolled in a single-blind, randomised crossover study; with data from 98 were used to assess efficacy and data from 110 to assess the safety profile. Ramosetron or granisetron was given intraveneously 15 min befire chemotherpy.
RESULTSThe ability of ramosetron to prevent emesis, nausea and anorexia was similar to granisetron during the first 6 h following the administration of chemotherapy, ciplatin or doxorubicin. However, during the first 24 h after chemotherapy, significant differences between ramosetron and granisetron appeared: emetic episode (P = 0.068), nausea (P = 0.006), and anorexia (P = 0.048) remained lower in ramosetron-treated patients. The safety profile of ramosetron was similar to that of granisetron and adverse events in both groups were generally mild and transient.
CONCLUSIONRamosetron is more potent and longer-lasting than granisetron in preventing chemotherapy-induced digestive disturbances.

Objective To explore the learning and memory impairment and pathology in hippocampus in rats after spinal cord contu-sion. Methods 36 adult female Sprague-Dawley rats were randomly divided into sham group (n=18) and spinal cord injury group (n=18). Spinal cord injury model at T10 was established with modified Allen's technique (10 g × 25 mm). The hindlimbs behavior of rats was rated with Basso-Beattie-Bresnahan (BBB) scores once a week for 5 weeks. They were tested with motor evoked potentials (MEP) and Morris wa-ter maze 5 weeks after injury. The pathology of hippocampus was detected with HE staining 1 week, 3 weeks and 5 weeks after injury, 4 rats in a group, repectively. Results The BBB scores were significantly lower in the spinal cord injury group than in the sham group at each time point (P<0.05). The latencies of both N1 and P1 wave of MEP were significantly longer in the spinal cord injury group than in the sham group (P<0.001), while the amplitudes were significantly less (P<0.001). For the Morris water maze, the latency of arrival platform were sig-nificantly longer in the spinal cord injury group than in the sham group (P<0.001), and the time in target was significantly less (P<0.001), with more systematic positioning or annular positioning, while the sham group with more space-based positioning. Morphologically abnor-mal cells in hippocampus gradually increased since the first week after injury, with the decrease of cells survival, while it was normal in the sham group. Conclusion Spinal cord contusion can cause learning and memory impairment in rats, which may be related to injury in hippo-campus.

Objective:To study the feasibility of indwelling ureteral stent for a short time (72 hours) in patients after uncomplicated retrograde intrarenal stone surgery(RIRS).Methods:The clinical data of 58 patients who underwent uncomplicated flexible ureteroscopic lithotripsy in Xuancheng People's Hospital from October 2020 to December 2021 were retrospectively analyzed. According to indwelling time of ureteral stent after surgery, the patients were divided into two groups. There were 26 cases indwelling within 72 hours after operation, named as the observation group, and 32 cases indwelling for about 3 weeks after operation, named as the control group. There was no significant difference in gender [male/female: 14/12 vs. 21/11], age [(43.4 ± 10.2) vs. (43.9 ± 11.9) years old], affected side [left/right: 17/9 vs. 20/12], and maximum diameter of stones [(9.3 ± 1.8) mm vs. (9.7 ± 1.9) mm] between the observation group and the control group. All patients in the two groups underwent unilateral ureteroscopic lithotripsy under general anesthesia. The stone removal rate, recovery of water accumulation and incidence of postoperative complications in the first and third months after the surgery were compared.Results:There was no statistical difference between the observation group and the control group in the stone removal rate [100.0% (26/26) vs. 96.9% (31/32)] and recovery of hydronephrosis [100.0% (26/26) vs. 96.9% (31/32)] at the first month after surgery. All the stones were removed and all the hydronephrosis recovery in the two groups at the 3rd month after surgery. The rates of postoperative lumbar and abdominal pain [3.9% (1/26) vs. 28.1% (9/32)], carnal hematuria [3.9% (1/26) vs. 59.4% (19/32)], urinary tract infection [0 vs. 15.6% (5/32)], and bladder irritation [0 vs. 68.8% (22/32)] in the observation group were significantly lower than those in the control group ( P<0.05). Conclusions:Indwelling a ureteral stent for a short time (72 hours) after uncomplicated RIRS does not affect the surgical effect and does reduce the risk of complications as well as promote rapid postoperative recovery.

OBJECTIVETo evaluate the efficacy and safety of nausea oral, disintegrating buccal tablet (DBT) in the prevention of gastrointestinal reaction induced by anticancer drugs (cisplatin DDP 30 - 50 mg/m(2) or adramycin ADM >/= 40 mg/m(2)), as compared with those of kytril tablets.
METHODSA multicenter, open and randomized self-crossover control trial was carried out with all the eligible patients randomized into AB or BA group. Patients in AB group were given nausea 0.1 mg as buccal tablet one hour before chemotherapy in the first cycle and kytril tablet 2 mg in the second cycle, those in BA group were given these drugs in the reverse order.
RESULTSSeventy-three patients were allotted to this study, including 44 patients in DDP-arm and 29 in ADM-arm. Sixty-two patients were evaluable for response and 70 patients for safety. Nausea DBT was as effective as kytril tablet in the control of anorexia, nausea and vomiting during the first 24 hours after chemotherapy, with response rates of 74.2%, 77.4%, 83.9% in nausea DBT and 74.2%, 71.0%, 88.7% DBT in kytril tablets. A high efficacy in the control of vommitting induced by cisplatin was observed in both nausea DBT and kytril tablets. The complete control rates and overall control rates were 83.3%, 91.7% in nausea DBT and 86.1%, 97.2% in kytril tablets, respectively. The side effects of nausea DBT were head heaviness, dry mouth and somnolence, which were mild and comparable with kytril in their frequencies.
CONCLUSIONNausea disintegrating buccal tablet is able to effectively prevent gastrointestinal reaction induced by anticancer drugs, with efficacy and side effects similar to kytril tablets. Nausea DB tablet, an intraoral disintegrator, is very convenient for patients who can not swallow tablets for various reasons.
