Objective To evaluate the efficacy and safety of ureteroscopic endo-incision and drainage in the treatment of renal cysts.Methods Thirty cases(19 females and 11 males)of renal cysts(1 1 parapelvie cysts,15 simple cysts.and 4 multiple cysts)were treated with ureteroscopic endo-incision and drainage.The renal cysts were located in renal pelvis,and opened and decompressed by electrotme with ureteroscope.Double J stent was placed afterwards.Urinary and blood biochemistry were tested post-operatively.Results All the operations were successfully completed with no severe complication.The cyst managing time ranged from 15 tO 45 min.Urinary biochemistry(urinary protein and glucose)turned normal 1 2 days after the surgery.Patients were followed up for 3 to 9 months.Renal cysts disappeared in 24 cases,diminished in 4 cases,and recurred in 2 cases.Conclusion Application of ureteroscopic technique in the treatment of renal cyst is safe,effective and minimally invasive.

Objective: To assess the clinical efficacy of Xuebijing injection in the prevention of postoperative systemic inflammatory response syndrome (SIRS) in the patients with ureteral stones and urinary tract infection during the perioperative period of ureteroscopy.Methods: Totally 64 cases with ureteral stones complicated with urinary tract infection treated with ureteroscopy were selected as the subjects and divided into two groups according to the digital method.The 32 cases in the control group were given the conventional antibiotics during the perioperative period for preventing the incidence of SIRS, and the observation group was given 500ml Xuebijing added to 100ml normal saline for intravenous drip additionally.The incidence of SIRS and the laboratory indicators after the operation were observed and compared between the groups.Results: The incidence of postoperative SIRS of the observation group was 9.38% , which was lower than that of the control group (34.38% , P <0.05);the incidence of sepsis of the observation group was 0%, while there was no statisticcally difference bettween the two groups(P＞0.05).The C-reactive protein (CRP), procalcitonin (PCT), leucocyte count and endotoxin in the observation group on the 2nd, 4th and 6th day after the operation were better than those in the control group, and the difference was statistically significant (P＜0.05).Conclusion: Xuebijing injection combined with antibiotics has significant clinical effect on the incidence of SIRS after ureteroscopy in the patients with ureteral stones and urinary tract infection, which can effectively improve the clinical indicators and reduce the incidence of sepsis, and is worthy of clinical promoted application.

BACKGROUND: Minimally invasive total hip arthroplasty is less invasive and has less tissue injury than traditional approach. However, perioperative anemia is still common, affecting hip function recovery and increasing patient burden. OBJECTIVE: To assess the curative effects of recombinant human erythropoietin on hemorrhagic anemia after minimally invasive total hip arthroplasty. METHODS: Clinical data of 35 patients undergoing SuperPATH minimally invasive total hip arthroplasty in the Department of Orthopedic Surgery, the Affiliated Hospital/Clinical Medical College of Chengdu University were collected. The patients were divided into the control group (n=17) and the erythropoietin group (n=18) according to the presence and absence of erythropoietin. The patients in the erythropoietin group were subcutaneously injected with recombinant human erythropoietin 3 days before replacement, once a day, lasting to 8 days after operation, for 12 consecutive days. During erythropoietin administration, iron sucrose was added once a day. Tranexamic acid 1 g was intravenously infused 0.5 hour before replacement, and 1 g for washing medullary cavity during replacement. The patients in the control group only took iron sucrose, once a day, adding tranexamic acid through intravenous infusion 0.5 hour before replacement. Levels of hemoglobin and hematocrit were monitored on the day of admission, the preoperative 3 days, the operation day, the postoperative 4 days and the postoperative 8 days. The operation time, blood loss, Visual Analogue Scale pain score 4 days before and after replacement and Harris hip function score before replacement, 4 and 8 days after replacement were recorded. RESULTS AND CONCLUSION: (1) Baseline data were not significantly different between the two groups (P > 0.05). (2) Visual Analogue Scale pain score significantly decreased 4 days after replacement in both groups (P < 0.05), and was not significantly different between both groups at various time points (P > 0.05). Harris hip score was not significantly different before and 1 day after replacement between the two groups (P > 0.05). At 4 days after replacement, Harris hip score was significantly higher in the erythropoietin group than in the control group (P< 0.05). Mean blood loss and operation time were not significantly different between the two groups (P > 0.05). (3) Levels of hemoglobin and hematocrit were not significantly different on the day of admission and 1 day before replacement (P > 0.05). Levels of hemoglobin and hematocrit were higher in the erythropoietin group than in the control group during emergency examination, 4 and 8 days after replacement (P< 0.05). The changes in levels of hemoglobin and hematocrit were consistent in different groups. The decreased trend was smooth, but the increased trend was relatively steep in the erythropoietin group. (4) Results confirmed that recombinant human erythropoietin combined with iron sucrose combined adding tranexamic acid, can effectively improve the anemia in perioperative period of minimally invasive total hip arthroplasty. Moreover, hemoglobin levels can increase to the stable and normal levels.

AIMUsing GeneChip to analyze the changes in genes expression of brain potassium, sodium and calcium channels after chronic treatment with nicotine.

METHODSAnimals were treated with nicotine at the doses of 2.4 mg/kg sc. twice a day for 14 days. RNA was extracted from the whole brain samples and converted to double-stranded cDNA and then to biotinylated cRNA. The biotinylated cRNA was fragmented, and hybridized to GeneChip (Affymetrix Rat Neurobiology U34). The chips were scanned with a probe array scanner, and the data were analyzed with the Affymetrix Microarray Analysis Suite (MAS). The GeneChip data were confirmed u sing RT-PCR.

RESULTSAfter treatment with chronic nicotine, transcripts of potassium, sodium and calcium channels showed altered expression. K+ channel: outward rectifier K+ channel and Ca2(+)-activated K+ channel were down-regulated, other voltage-dependent K+ channel including Kv2.3r were up-regulated. Voltage-dependent Na+ channel: beta2 subunit was increased, alpha subunit and beta1 subunit were decreased. Beta3 subunit of Ca2+ channel was up-regulated.

CONCLUSIONChronic exposure to nicotine not only desensitized nicotinic receptors, but also effected genes expression, of important ion channels, such as sodium channels, potassium channels and calcium channels.

Secondary metabolites are the result of that plant interaction with biological and non-biological factors in the long-term evolution process, and play an important role in plant growth, development and physiology. The effective components of medicinal plant are usually the secondary metabolites in plant cells, and the synthesis of them are affected by a variety of factors, such as environmental impact. Acquirement of the secondary metabolites via callus culture has the advantage of low cost and less environmental impact. The synthesis and accumulation of medicinal plant secondary metabolites are not only controlled by light, temperature and pH, but also infected by germplasm, plant growth regulator and elicitor. This article presents a review of the influencing factors, and provides a basis for further study and development.

Activation of acid-sensing ion channels (ASICs) plays an important role in neuroinflammation.Macrophage recruitment to the sites of inflammation is an essential step in host defense.ASIC 1 and ASIC3 have been reported to mediate the endocytosis and maturation of bone marrow derived macrophages.However,the expression and inflammation-related functions of ASICs in RAW 264.7 cells,another common macrophage,are still elusive.In the present study,we first demonstrated the presence of ASIC 1,ASIC2a and ASIC3 in RAW 264.7 macrophage cell line by using reverse transcriptase polymerase chain reaction (RT-PCR),Western blotting and immunofluorescence experiments.The non-specific ASICs inhibitor amiloride and specific homomeric ASIC 1 a blocker PcTx 1 reduced the production of iNOS and COX-2 by LPS-induced activating RAW 264.7 cells.Furthermore,not only amiloride but also PcTx 1 inhibited the migration and LPS-induced apoptosis of RAW 264.7 cells.Taken together,our findings suggest that ASICs promote the inflammatory response and apoptosis of RAW 264.7 cells,and ASICs may serve as a potential novel target for immunological disease therapy.

Objective To investigate the prognostic sequelae in neontes with hypoxic-ischemic encephalopathy (HIE) and ven-tricnlar dilatation.Methods Seventy-six full term newborns infants with HIE were followed up at the age from 3 to 19 months after therapy. Twenty-five infants among them were followed up by telephone in the epidemic period of SARS.Results Among 76 infants of 88 newborn infants with HIE(84.6%), 73 infants were normal (96.1% ). 1 infant had cerebral palsy (1.3%), 2 infants died (2.6 %).Among 39 cases with mild HIE, none of them had cerebral sequelae; among moderate HIE. 1 infant had cerebral palsy (2.9%) 1 infant died (2. 9 %), interlenkin-4 among severe HIE 50 % died (P00.5 The poor outcome of HIE in those infants were related to intrauterine growth retardation,severe birth asphyxia;and inadequate treatment.Cranial ultra-sonography of 49 infants were done on follow-up,and 12 of them (24.5 % ) had ventricular dilatations, which appeared after birth with 6 infants. Others occurred on follow-up with 1 infant had cerobral palsy,all ventricular dilatations recovered to normal at 12- 19 months except the cerebral palsy.Conclusions The poor outcome of HIE depends on the infants with intranterine growth relarda-tion,severe birth asphyxia and inadequate treatment.The prognosis of transient ventrealar ddatation are good except cerebral palsy.J Appl Clin pediatr,2004,19(12) : 1045- 1047

To investigate the expression of NF-kappaB in acute leukemia and its relationship with P21, and matrix metalloproteinases (MMP), the expression of NF-kappaB, P21, MMP-2 and MMP-9 in bone marrow cells from patients with acute leukemia (AL) was detected using immunocytochemical technique. The results showed that the expression ratios of NF-kappaB, P21, MMP-2 and MMP-9 in untreated AL group were significantly higher than those in remission and normal control groups (P < 0.05), and no obvious difference was seen between remission and normal control groups. The expression of NF-kappaB was correlated with that of P21, MMP-2 and MMP-9 (r = 0.767, 0.729 and 0.803, respectively, P < 0.05). This study indicated that P21 protein, encoded by oncogene Ras, and NF-kappaB were super-expressed in leukemia cells. In conclusion, after activation by Ras, NF-kappaB combined with the kappaB sequences of MMP-2 and MMP-9 genes, then upregulated their expression. MMP might enhance the degradative function of leukemic cell, thus to make cells easier to cross through the bone marrow barrier and release into blood.

The aim of this study was to investigate the effect of evodiamine on the proliferation and the immune function of thymocytes and splenocyte of mice from three germlines, which were 8 weeks old masculinity BALB/c, C57BL/6 and F1 hybridization mice. Cells of thymus and spleen were harvested and prepared as unicellular suspension. Cell proliferation was detected by MTT method, while the concentration of IL-2 was detected by ELISA, mRNA levels of bcl-2 and cdk2 in cells treated with evodiamine were detected by RT-PCR, the apoptosis rate and intracellular reactive oxygen species (ROS) concentration were analyzed by FCM, and the protein levels of BCL-2, CDK2 and BAX were determined by fluorescence microscope. The results indicated that at 0.5, 0.75 and 1 micromol/L, evodiamine inhibited the proliferation and externalization of thymocytes and splenocytes stimulated with ConA (p < 0.05). At 0.75 micromol/L, evodiamine inhibited the secretion of IL-2, decreased the mRNA level of bcl-2 and cdk2, and induced apoptosis of thymocytes and splenocytes (p < 0.05). Intracellular ROS concentration increased significantly after treatment with evodiamine for 12 hours (p < 0.05). The death rate increased at a prolong period of time. After treatment with evodiamine for 24 and 48 hours, the cells were divided into two groups, one of which was negatively stained by 2 7-dichlorofluorescein (DCF), which indicated that ROS level decreased significantly in the dying cells. It is concluded that evodiamine inhibits proliferation and induces apoptosis of thymocytes and splenocytes from different germline mice, and at the same time decreases secretion of IL-2 through down-regulating bcl-2 and cdk2 levels.
