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 study the instance of deep venous thrombosis(DVT) complicated by preoperative lower extremity close fracture.

METHODSRetrospectively analyzed the clinical data of 54 patients with DVT (through color Doppler to final diagnosis) complicated by preoperative lower extremity close fracture from March 2008 to February 2009, and explored the concomitant reason of DVT. There were 23 males and 31 females with age for 23-95 years old.

RESULTSDVT including thrombus of ilio-venae external, thrombus of femoral vein, thrombus of popliteal vein, thrombus of posterior tibial veins and thrombus of soleus venae. The instance of DVT complicated by preoperative lower extremity close fracture: (1) The age of 23 cases (42.59%) more than 70 years. (2) 11 cases (20.37%) combined with syndrome, 2 cases had hypertension, 3 cases had hypertension and diabetes, 2 cases hypertension and cerbral infarction, 4 cases had hypertension, diabetes and coronary heart disease. (3) 10 cases (18.51%) were multi-fractures. (4) 28 cases (51.85%) occurred DVT at 7-14 days after lower extremity close fracture.

CONCLUSIONAdvanced age, complicating hypertension, diabetes, coronary heart disease, cerbral infarction, multi-fractures may be lead to DVT. Multitudinous DVT occurred at 7-14 days after fracture, as early as possible operation has important significance on prevention DVT to decrease risk of pulmonary embolism.

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.

Objective To analyze the outcome of surveillance results on plague and to provide the evidences for the policy making in Longlin county Guangxi. Methods The epidemic data and the surveillance results of plague were analyzed and assessed with epidemiology methods in Longlin county Guangxi from 2000 to 2009, and the density of rodents, the rodents infected with flea, flea index and other indicators were calculated. Regional composition of the rats and fleas were analyzed. Results A totally of 4829 rats were captured and 4737 fleas were collected in the past 10 years, Rattus Flavipestus(81.92%,3956/4829) and Xenopsylla Cheopis (79.04%,3744/4737) were dominant species. The annual average density of rodents, the rodents infected with flea, index of flea were 3.30%(4829/146 206), 27.99%(1351/4827) and 0.98(4737/4827), respectively. A totally of 4792 rats were examined and 10 strains Yersinia Pestis were isolated. Indirect hemorrhagic assessed(IHA) was used to test the F1 antibody against plague in the blood serum of the rats and indicator animals, and 3 positive rats and 24 positive animals were found, respectively. Twenty seven natural villages in 3 towns had been involved in the plague. Conclusions The plague foci exists in Longlin county of Guangxi province. The plague foci in the areas have the same feature with the plague foci of Rattus Flavipectus. There is a potential risk for plague in this region, we should improve the quality of surveillance, increase indicator animals of the plague, and try to apply new surveillance method.

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.

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 study the clinicopathologic and immunohistochemical features of mesenchymal chondrosarcoma.

METHODSThe clinical and histologic features of 23 cases of mesenchymal chondrosarcoma were analyzed. Immunohistochemical study was also performed in 14 of the cases.

RESULTSThe age of patients ranged from 12 to 47 years. Fourteen of them occurred in males. Thirteen cases involved the bony skeleton and 5 cases affected the soft tissue. The patients presented with pain and/or swelling. Histologically, the tumor consisted of a mixture of undifferentiated small round cells and hyaline cartilage. Transition between the two components was demonstrated and growth plate-like cartilage was observed. Immunohistochemical study showed that the small round cells were positive for Sox9 (14/14), CD99 (12/14), vimentin (6/14), CD56 (4/14), CD57 (4/14), neuron-specific enolase (3/14) and desmin(1/14). They were negative for Coll-II, S-100 protein, epithelial membrane antigen, pan-cytokeratin, synaptophysin, chromogranin A, CD34 and c-erbB2.

CONCLUSIONSMesenchymal chondrosarcoma is a rare malignant tumor. Thorough histologic examination, when coupled with immunohistochemical findings, is helpful in arriving at a correct diagnosis.

OBJECTIVETo study the clinicopathologic features of intravascular large B-cell lymphoma (IVLBCL).

METHODSTwo autopsy cases of IVLBCL were retrieved from the archival file. The clinicopathologic features, immunohistochemistry and molecular findings were studied.

RESULTSThe deceased were 70-year-old and 50-year-old males. Both of them had complained of a sudden onset of weakness and numbness of lower extremities. The clinical course deteriorated rapidly, with multi-organ failure. They died 85 days and 44 days after the presentation, respectively. Post-mortem examination did not reveal any mass lesion, except the presence of multiple skin and epicardium nodules, ranging from 0.5 cm to 2.5 cm in diameter, in the first patient. Pericardial effusion, ascites and pleural effusion were also observed. Histologically, neoplastic lymphoid cells filled up the small vessel lumina in many organs, including brain, hypophysis, spinal cord, spinal nerve roots, heart, lungs, kidneys, liver, spleen, digestive tract, pancreas, adrenal, thyroid, testes and lymph nodes. The tumor cells were relatively monotonous and of medium to large in size with round vesicular nuclei and 1 to 3 small basophilic nucleoli. Immunohistochemical study showed that the lymphoma cells expressed B-cell markers CD20 and CD79a, occasionally positive for CD5 and bcl-2 but negative for CD3, bcl-6, CD10, CD30, myeloperoxidase and cytokeratin. In-situ hybridization for Epstein-Barr virus-encoded RNA was negative. The proliferative index, as demonstrated by Ki-67 staining, was about 80%. Molecular study showed the presence of immunoglobulin heavy chain gene rearrangement in both cases, T-cell receptor-gamma gene rearrangement was not found.

CONCLUSIONSIVLBCL may present as neurological disturbance and carries distinctive morphologic characteristics, immunophenotype and molecular findings. The prognosis of this disease is often dismal.

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.
