Objective The studies on tissue culture and cytological observations of leaf explants of Curculigo orchioides were conducted in order to provide the basis for the rapid propagation of C. orchioides. Methods Young leaf explants of C. orchioides were cultured on MS basal media. Differences in the callus induction and plantlet regeneration rate were observed by different light treatment as well as chemical factors like different phytohormones, casein hydrolysate (CH), and activated charcoal (AC) concentrations. Paraffin method was used to cytological observation. Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L+2, 4-D 2.5 mg/L, and 300 mg/L CH+0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus. The buds developed on the peripheral parts of the calli, but the roots developed in the regions deep within the calli. Conclusion Tissue culture of young leaf explants of C. orchioides can make the propagation of C. orchioides rapid.

Objective:To summarize the experience of Bacillus Calmette-Guerin(BCG) in the treatment of bladder cancer secondary to renal transplantation.Methods:The clinical data of 5 patients who underwent BCG bladder irrigation after secondary bladder cancer after kidney transplantation in Tianjin First Central Hospital from January 2015 to December 2019 were analyzed. There were 1 male and 4 female cases. During the period of immunosuppression after transplantation, 1 case developed secondary high-level non-muscular invasive bladder cancer (NMIBC), 3 cases developed secondary low-grade NMIBC, and 1 case developed secondary glandular cystitis (4 cases). The mean age of the 5 patients with secondary bladder cancer was 59.7±4.0 years. Case one with high level NMIBC was treated with transurethral resection of bladder tumor (TURBT) and postoperative irrigation of epirubicin. Case 3 and 5 with low-level NMIBC accepted regular postoperative irrigation of gemcitabine. No irrigative therapy was performed in case 2. Bladder cancer recurred in case 1, 2, 3 and 5 after 20.1±9.7 months. TURBT was observed in all the 4 patients, among which 3 were of high grade NMIBC and 1 was of low grade NMIBC. Four patients were irrigated with BCG 2 weeks after operation. Postoperative pathology indicated low-level NMIBC in case 4, and BCG was irrigated 2 weeks after the operation. During perfusion therapy, immunosuppressive agents were continued.Results:During BCG perfusion, 4 of the 5 cases showed BCG related local inflammation, among which 2 cases presented symptoms of bladder irritation, 1 case presented hematuria, and 1 case presented hematuria with low fever. Patients with frequent urination, pain in urine, hematuria and other symptoms improved after drinking plenty of water, taking bed rest and taking levofloxacin (0.5g/ day ×7 days). Patients with low fever were treated with antipyretic treatment. No antituberculous agents were used prophylactically during BCG perfusion. There were no symptoms of tuberculosis infection or sepsis. The function of transplantated kidney was normal and no tendency of rejection. The 5 patients were followed up for 7-24 months, 1 patient was lost to follow-up after 7 months of BCG bladder perfusion, and no tumor recurrence or metastasis was found in 5 patients during the follow-up.Conclusions:The use of immunosuppressive agents does not reduce the biological activity of BCG, and BCG does not increase the risk of systemic toxicity or affect the function of transplanted kidneys in immunocompromised patients. BCG is a treatment option for bladder cancer secondary to renal transplantation.

Objective The clinical manifestations of Parkinson''s disease (PD) are divided into non-motor symptoms and motor symptoms.Constipation is one of the common symptoms of non-motor symptoms of the disease.Constipation symptoms in PD generally occur earlier for 5~20 years, while drug treatment for PD constipation can lead to gastrointestinal damage.This study investigated the improvement in the treatment of anorectal dynamics and constipation symptoms in Parkinson''s disease by oral mosapride and press-needle therapy of Shu-Mu point.Methods 60 patients diagnosed as constipation of Parkinson''s disease were randomly divided into control group and treatment group, 30 cases in each group;patients in the control group were treated with oral mosapride tablets, while patients in the treatment group received press-needle therapy, three times per week.The observation course in both groups last for three months and follow-up visits were conducted before and after the course.Efficacy evaluation, PAC-QOL scale and anorectal dynamic examination were applied in the follow-up visit.Results The efficiency of treatment group was 81.7%, significantly higher than control group (70%), representing significant difference between the two groups (P<0.05).Both the methods could improve the PAC-QOL scale, and significant difference was found in comparison to that before the treatment(P<0.01), while no statistical significance was found between treatment group and control group after treatment(P>0.05).As to the anorectal dynamics, significant difference was found before and after the treatment in both groups (P<0.05, P<0.01), while no statistical significance were found between the two groups after treatment(P>0.05).Conclusion Both oral mosapride and press-needle can improve the quality of life and anorectal dynamics for PD patients, representing no significant difference.However, compared with mosapride, the overall efficacy of press-needle is better in improving the symptoms of constipation in PD, featuring more convenience, higher safety, less pain and no side effect, and it is worthy of clinical application.

Objective To illustrate and analyze the clinical feature and treatment of botulism introduced by illegal injection of botulinum neurotoxins (BoNT),in order to provide some evidence for early diagnosis and treatment strategy.Methods Retrospective analysis of 13 botulism patients was performed in this article.All of the patients were suffered from illegal injection of botulinum neurotox in products.Support treatments were carried out according to their severe grade,and the courses of disease and the curative effects were observed.Results A new category was first identified as injection induced botulism to describe such a situation of cosmetic injection out of the hospital with neither the prescribed botulinum toxin product nor a doctor.One in 13 patients graded mild botulism,the other 12 patients graded middle level.The processes of the new botulism had 4 stages:preclinical stage (4 days),progressive stage (9.8 days),apical stage (9.1 days) and restoration stage (5.2 months).The relationships of a positive correlation in injection dose and the length of progressive stage were identified,while a negative correlation with the length of preclinical stage was revealed.Conclusions The earlier2-3 weeks after illegal injection are crucial for intense care because of the acceleration in this period.Absolute rest and active treatments as well as antitoxinum are benefit for the recovery of patients.

F0.01(1,5)=16. 30,P0. 05). Conclusion Laboratory results thus suggest that infection intensity is related to snail size per se, whereas prevalence in the field is related to snail size only through the correlation between size and age. In addition, under these experimental conditions, infected snails were no larger than uninfected snails, so the gigantism snails observed in the field might not be attributable to Trichobilharzia-induced effect.

Objective: To compare nephrotoxicity and ototoxicity of gentamycin administered in single dose or multiple dose daily in guinea pigs. Methods: Thirty two male guinea pigs were divided into physiological saline control, single dose group daily (gentamycin, 120 mg/kg, 1/d) and multiple dose group daily (gentamycin, 60 mg/kg, 2/d). The physiopathology of renal and cochlea in guinea pigs were examined using auditory brainstem response (ABR), SC sound irritation and electron microscope. The gentamycin concentrations in serum and in perilymph were monitored by fluorescene polarization immunoassay (FPIA). Results: (1) Compared with control group, both gentamycin single and mulitiple daily doses injuried kidney and cochlea to some extent.The injury of multiple dose groups were worse than that the single dose groups ( P

Objective To compare the analgesic effect ofHuamoyan Keli(HMYKL) between Kunming mice and BALB/c mice.Methods Eighty Kunming mice and eighty BALB/c mice were randomly divided into five groups, respectively: a control group, a ibuprofen group, a HMYKL high-dose group(13.98 g crude dru g/kg), HMYKL middle-dose group(6.99 g crude drug/kg)and a HMYKL low-dose group(3.50 g crude dru g/kg). There were 16 mice in each group with 8 male mice and 8 female mice. Drugs were administered intragastrically daily for 5 days. After 1 h of drug treatment on day 4, the latency of tail-flick response was evaluated using illuminated pain measurement instrument. After the last drug treatment, pain model was established by i.p. acetic acid, writhing latency and writhing times were recorded to evaluate the analgesic effect of HMYKL.Results In tail-flick test, there was no statistical difference among male and female Kunming mice in the HMYKL groups. Among male BALB/c mice, the latency in HMYKL middle-dose group was significantly longer than that in the control group(4.84±1.16 minvs. 3.93±0.76 min,P<0.05). In writhing test, compared with control group(19.06±6.34), the writhing times among BALB/c mice were decreased in HMYKL high-dose group(8.56±6.19), HMYKL middle-dose group(5.73±3.17), HMYKL low-dose group(6.88±4.59)(allP<0.01).Conclusion All dose groups of HMYKL showed good analgesic effect on the pain induced by chemical stimulation and there was no sex difference. Kunming mice were not suitable for the evaluation of the analgesic pharmacodynamics because of their large individual difference. On contrast, BALB/c mice which had less individual difference could be used to produce the model of pain.

Bacterial liver abscess is a rare and life-threatening disease, and, clinically, its incidence has gradually increased in recent years. In terms of its treatment, percutaneous puncturing drainage combined with antibiotics has been the first-line therapeutic means, and surgical procedures are often used for patients in whom the interventional drainage is ineffective or in whom the liver abscess is complicated by abdominal disease that needs surgical management. Percutaneous catheter drainage and percutaneous fine needle aspiration, regarded as the two most commonly used interventional drainage methods, have been widely employed in the treatment of bacterial liver abscess; and percutaneous catheter drainage is more commonly adopted in clinical practice. Although the prognosis of bacterial liver abscess has been improved significantly, there is still a certain fatality rate. There is still no a well-accepted consensus on treatment guidelines. Moreover, there are still many controversies over the indications of percutaneous puncturing drainage. Based on a comprehensive review of the domestic and foreign literature, this paper aims to make a detailed introduction concerning percutaneous puncturing drainage for the treatment of bacterial liver abscess, focusing on its development history, curative effect and prognosis, and, in order to guide the clinical practice, the principles of the use of antibiotics, the comparison of clinical effect with surgery and the therapeutic indications will be also discussed.
