Three types of new high-efficiency phosphate fertilizers were made when pillared clays at certain proportions were added into ground phosphate rock. Chemical analyses showed that their soluble phosphorus content decreased more than that of superphosphate. Pot experiment showed that, under equal weights, the new fertilizers increased their efficiency by a large margin over that of superphosphate. Researches on their structures by means of XRD, IR and EPR spectrum revealed that their crystal structures changed considerably, improving their activity and preventing the fixation of available phosphorus in the soil, and consequently, greatly improved the bioavailability and became the main cause of the increase of biomass.

Objective:To observe the lipid-lowering effect of different transdermal absorption enhancers applied to the herbal cake-partitioned moxibustion in hyperlipidemia model rabbits, and to explore the possible mechanism. Methods:Forty New-Zealand rabbits were randomly divided into 5 groups using the random number table method, with 8 rats in each group. Rabbits in the blank group were fed routinely with normal diet; rabbits in the other groups were fed with high-fat diet for 12 weeks to establish the hyperlipidemia model. Rabbits in the blank and the model groups were not treated. After the model was prepared, rabbits in the non-transdermal absorption enhancer group received herbal cake-partitioned moxibustion without transdermal absorption enhancer; rabbits in the laurocapram group and the borneol group received herbal cake-partitioned moxibustion with laurocapram or borneol respectively. After 4 weeks of treatment, serum was collected for enzyme-linked immunosorbent assay (ELISA), and the liver tissues were isolated for immunohistochemistry, quantitative polymerase chain reaction (qPCR) and Western-blotting (WB) detection. Results: Serum ELISA results showed that leptin was significantly decreased in the model group compared with the blank group (P＜0.05); compared with the model group, leptin was significantly increased in the non-transdermal absorption enhancer, the laurocapram and the borneol groups (all P＜0.05); compared with the non-transdermal absorption enhancer group, leptin was significantly increased in the laurocapram group and the borneol group (both P＜0.05); there was no significant difference in leptin between the laurocapram and the borneol groups (P＞0.05). The qPCR results of rabbit liver tissues showed that the mRNA expressions of leptin, Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in the model group were significantly lower than those in the blank group (all P＜0.05); compared with the model group, the mRNA expressions of leptin, leptin receptor (LR), JAK2 and STAT3 in the non-transdermal absorption enhancer, the laurocapram and the borneol groups were significantly increased (all P＜0.05); compared with the non-transdermal absorption enhancer group, the mRNA expressions of leptin, LR, JAK2 and STAT3 in the laurocapram and the borneol groups were significantly increased (all P＜0.05); compared with the laurocapram group, the mRNA expressions of leptin, LR, JAK2 and STAT3 in the borneol group were significantly increased (P＜0.05). The trend of immunohistochemistry and WB detection results was basically consistent with the qPCR assay results. The immunohistochemistry and WB detection results of phosphorylated JAK2 (phospho-JAK2) and phosphorylated STAT3 (phospho-STAT3) were basically consistent with those of JAK2 and STAT3. Conclusion: The molecular expression of Leptin/JAK2/STAT3 pathway in the hyperlipidemia model rabbits was decreased. The molecular expression of Leptin/JAK2/STAT3 pathway was significantly increased after the herbal cake-partitioned moxibustion. The application of laurocapram and borneol, as transdermal absorption enhancers, in the herbal cake-partitioned moxibustion could more obviously up-regulate the factors of the Leptin/JAK2/STAT3 lipid-regulating pathway than the herbal cake-partitioned moxibustion alone.

OBJECTIVETo evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program.

METHODSClinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out.

RESULTSThe 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05).

CONCLUSIONThe prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.

Objective: To observe the effects of laurocapram and borneol as transdermal penetration enhancers applied to herbal cake-partitioned moxibustion on liver lipids, hormone-sensitive lipase (HSL) and hydroxymethylglutaryl CoA (HMG-CoA) reductase in hyperlipidemia rabbits.Methods: Forty New-Zealand rabbits were randomly divided into 5 groups using the random number table method, with 8 rats in each group. Rabbits in the blank group were fed routinely with a normal diet; rabbits in the other groups were fed with high-fat diet for 12 weeks to establish the hyperlipidemia model. Rabbits in the blank and the model groups were not given any intervention. After the model was prepared successfully, rabbits in the non-transdermal penetration enhancer group received herbal cake-partitioned moxibustion without transdermal penetration enhancers; rabbits in the laurocapram group and the borneol group received herbal cake-partitioned moxibustion with laurocapram or borneol respectively. After 4 weeks of treatment, the serum was isolated and enzyme-linked immunosorbent assay (ELISA) was applied for the detection of HSL and HMG-CoA reductase. The liver tissues were isolated, and total cholesterol (TC) and triglycerides (TG) were measured by enzymatic methods. One-step method was applied for high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) detection, and transmission turbidimetry was for apolipoprotein A1 (Apo-A1) and apolipoprotein B (Apo-B) detection. Results: The serum concentrations of the drugs in the laurocapram and the borneol groups were significantly higher than those in the non-transdermal penetration enhancer group (both P<0.05); all drug penetrations in the borneol group were significantly higher than those in the laurocapram group (both P<0.05), except for tanshinone ⅡA. Compared with the non-transdermal penetration enhancer group, the HSL was significantly increased while the HMG-CoA reductase was significantly decreased in the laurocapram and the borneol groups (both P<0.05); between groups, the HSL in the borneol group was significantly higher than that in the laurocapram group (P<0.05). Compared with the blank group, the levels of LDL-C, TG, TC and Apo-B in rabbit liver were significantly increased in the model group (P<0.05); compared with the model group, the levels of LDL-C, TG, TC and Apo-B in the non-transdermal penetration enhancer, the laurocapram, and the borneol groups were significantly decreased (all P<0.05); between groups, the TG and TC in the laurocapram group and the LDL-C, TG, TC and Apo-B in the borneol group were significantly lower than those in the non-transdermal penetration enhancer group (all P<0.05), and the TG, LDL-C and Apo-B in the borneol group were significantly lower than those in the laurocapram group (all P<0.05). Compared with the blank group, the HDL-C and Apo-A1 were significantly decreased in the model group (both P<0.05), while compared with the model group, the HDL-C and Apo-A1 were significantly increased in the non-transdermal penetration enhancer, the laurocapram, and the borneol groups (all P<0.05). Between groups, the Apo-A1 in the laurocapram group, the HDL-C and Apo-A1 in the borneol group were significantly higher than those in the non-transdermal penetration enhancer group (all P<0.05).Conclusion: The application of laurocapram and borneol, as transdermal penetration enhancers, in herbal cake-partitioned moxibustion can promote the penetration of the drugs in the herbal cake, increase the levels of HDL-C and Apo-A1, improve the metabolism of HSL and HMG-CoA reductase, and also simultaneously reduce the levels of TC, TG, LDL-C and Apo-B in the liver. The transdermal penetration enhancement effect of borneol is slightly better than or equivalent to that of laurocapram.

OBJECTIVETo explore the Video-urodynamic characteristics of various neurogenic bladder.

METHODSA total of 1800 patients with neurogenic bladder were included in our study from December 2002 to June 2008. All patients underwent Video-urodynamic studies. Urodynamic data was collected and analyzed.

RESULTSUrodynamic study showed detrusor overactivity in 71%, of which 60% with uninhibited sphincter relaxation, and acontractile detrusor in 29% stroke patients. No upper urinary tract deterioration was found in all 42 stroke patients. Detrusor overactivity without sphincter dyssynergia was found in 70% patients with head trauma. Seven patients with Parkinson disease showed detrusor overactivity, of which 3 with delayed sphincter relaxation. Detrusor overactivity was found in 91% and detrusor sphincter dyssynergia in 83% supra-sacral spinal cord injured patients. Acontractile detrusor was found in 73% patients with conus medullaris and cauda equina injury. Overall, upper urinary tract changes were found in 12% and vesicoureteral reflux in 4% spinal cord injured patients. Urodynamic study showed acontractile detrusor in 81%, reduced compliance in 86%, upper urinary tract changes in 55% and vesicoureteral reflux in 33% patients with myelodysplasia. Most patients (92%) with protruded lumbar disc showed detrusor areflexia. Normal bladder compliance was found in 88% patients with protruded lumbar disc. Urodynamic study showed reduced bladder sensation in 81% and detrusor under-activity in 76% patients with diabetic urinary bladder disease.

CONCLUSIONSVideo-urodynamic study can provide the most detailed information about the bladder dysfunction. It is the most valuable examination before treatment of patients with neurogenic bladder.

OBJECTIVETo evaluate clinical efficacy of holmium laser enucleation of the prostate in the treatment of benign prostatic hyperplasia (BPH) and overactive bladder (OAB).

METHODSFrom May 2007 to May 2010, a total of 37 patients diagnosed BPH and OAB were treated by holmium laser enucleation of the prostate. After a mean follow-up of 4.9 months postoperatively, indices such as International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), residual urine volume and video urodynamics were monitored and statistically analyzed.

RESULTSThe mean preoperative IPSS and QOL score were 29.6 ± 5.2 and 4.3 ± 0.9, and decreased to 4.6 ± 1.2 and 1.2 ± 1.0 postoperative. The mean Qmax was (6 ± 3) ml/s preoperative and increased to (21 ± 5) ml/s postoperative. Preoperative average residual urine volume was (167 ± 11) ml, decreased to (41 ± 18) ml after operation. During follow-up, 86.5% patients' symptoms and quality of life improved continuously, however 13.5% patients existed residual postoperative OAB symptoms.

CONCLUSIONSWhen BPH with OAB patients exist bladder outlet obstruction, bladder outlet obstruction should be relieved first then OAB symptoms can be relieved in majority of patients, but some patients have residual symptoms.

Objective The aim of this study is to evaluate the clinical significance of High-risk Human Papilloma virus DNA Detection Kit(Cervista HPV HR) designed to the utilized in cervical cancer screening programs. Methods The investigation for Cervista HPV HR test is designed to detect 437 residual liquid-based cytology specimens collected during routine liquid-based Pap tests at standard care vistis and to identify the presence of HR HPV. We compared Cervista HPV HR Test against standard PCR,in order to examine the performance of Cervista HPV HR Test in populations with cervical intraepithelial neoplasia grade 2 + ( CIN 2, CIN 3 and Cancer, CIN 2 + ), and the capabilities of A5/A6, A7, A9 oligonucleotides of Cervista for predicting CIN2 +. Results The accuracy of Cervista compared to PCR with bi-directional sequencing was 88.26%. The positive percent of Cervista HPV HR Test and PCR were 38.96% and 29.08%, respectively. The sensitivity, specificity, negative predictive value (NPV) and positive predictive value ( PPV ) of Cervista HPV HR Test for the detection of CIN2 + were 98.46%,58.49% ,99. 54% and 29. 68%, respectively. The A9 oligonucleotides positivity percent was significantly higher in CIN2 + (odds ratio:24. 037,95% CI:10. 086 -57. 283). Conclusion The Cervista HPV HR test can be clinically used for detecting HR HPV types during routine cervical cancer screening. A9 oligonucleotides were also strongly associated with CIN2 + diagnosis, which is improtant in cervical cancer screening for triage to colposcopy.

OBJECTIVETo explore the efficacy of neuromodulation (including sacral neuromodulation and dorsal penile/clitoral nerve neuromodulation) for the treatment to neurogenic bowel dysfunction due to spinal cord injury.

METHODSFrom January 2006 to April 2008, 9 patients with neurogenic constipation after spinal cord injury underwent the therapy of neuromodulation, 1 patient underwent the therapy of sacral neuromodulation, 8 patients underwent the therapy of dorsal penile/clitoral nerve neuromodulation. The therapeutic efficacy was evaluated and followed up by means of Wexner constipation score.

RESULTSOne patient received permanent electrode and neurostimulator implantation and constipation were improved continuously. A significant improvement in the Wexner constipation score was observed compared with the preoperative baseline level (preoperative baseline: median 22; after implantation: median 9). Four patients were effective after the therapy of dorsal penile/clitoral nerve neuromodulation. Wexner constipation score decrease from 19 to 11 after 12 weeks dorsal penile/clitoral nerve neuromodulation. Patients also showed a significant improvement in their symptoms and quality of life during follow up.

CONCLUSIONSSacral neuromodulation and dorsal penile/clitoral nerve neuromodulation may be effective for some neurogenic constipation. However there are no methods successfully identify the candidate who will be beneficial before the procedure. Good quality research data are needed to evaluate the effects of sacral neuromodulation and dorsal penile/clitoral nerve neuromodulation for these conditions.

OBJECTIVETo evaluate the clinical efficacy of Jianpi Liqi Yiliu Formula (JLYF) combined with cytokine-induced killer (CIK) cells for treating patients with advanced hepatocellular carcinoma (HCC).

METHODSBetween January 2011 and January 2014, 60 advanced HCC patients were enrolled in this study, who were assigned to the treatment group and the control group according to their willingness for taking JLYF, 30 cases in each group. All patients received CIK cell treatment: 1 x 10⁹-3 x 10⁹ each time, by intravenous dripping from the 1st day to the 3rd day, once per day. Besides, patients in the treatment group took JLYF decoction, while those in the control group took Chinese medical decoction by syndrome typing. All patients received treatment of at least two cycles. The time to progression (TTP) , overall survival (OS), disease control rate (DCR), performance status scale (PS), Child-Pugh scale, and adverse reactions were observed, and subgroup analyzed.

RESULTSTo May 31, 2014, all patients reached the clinical endpoint. TTP was 3.5 months (95% Cl: 3.30-4.10) in the treatment group, better than that (2.5 months, 95% CI: 2.32-2.68) of the control group (P < 0.05). DCR was 36.7% in the treatment group and 30.0% in the control group (P > 0.05). OS was 5.2 months (95% CI: 4.53-5.87) in the treatment group and 4.6 months (95% CI: 4.06-5.14) in the control group (P > 0.05). The PS scale was 1.60 ± 0.10 after treatment, lower than that (1.80 ± 0.09) before treatment in the treatment group (P < 0.05). When the PS scale was 0-2 or Child-Pugh scale was class A, TTP was longer in the treatment group than in the control group (P < 0.05). No adverse reaction occurred in the two groups during the treatment course.

CONCLUSIONSThe combination of JLYF with ClK cell treatment could prolong advanced HCC patients' TTP, improve PS scale, as compared with syndrome typed Chinese medical decoction treatment group. Besides, when the PS scale was 0-2 or Child-Pugh scale was class A, it was a better treatment program for advanced HCC patients.
