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.

OBJECTIVESThe investigation of the testicular volume, the penis length and the T, FSH, LH, PRL levels in serum were taken in 289 adolescent males to provide the valuable data for andrology.

METHODSThe adolescent males were grouped according to their age. The testicular volume was measured with testicular model and the T, FSH, LH, PRL levels in serum were determined by immunoenzymetric assay.

RESULTSThe male sexual development was rapid from age 11 to 16 and close to that of adult at age 18. Serum PRL of adolescent males was higher than that of adult males.

CONCLUSIONSThe age 11 to 16 is a period of rapid growth in sexual maturation. PRL may play an important role in sexual maturation.

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 investigate BCL-6 gene mutations in B-cell non-Hodgkin lymphomas (B-NHL) and their implications in lymphoma pathogenesis.

METHODSPolymerase chain reaction (PCR) and direct DNA sequencing methods were used to identify mutations in the 5'-noncoding region of BCL-6 gene in 135 cases of B-NHL, 5 cases of T-NHL, 5 cases of nodular lymphocyte predominance Hodgkin's lymphoma (NLPHL) and 10 cases of reactive hyperplasia of lymph node.

RESULTSMutations were identified in 6 cases of nodal DLBCL (27.3%), 4 cases of FL (22.2%), 4 cases of MALT lymphoma (22.2%), 4 cases of extranodal DLBCL (20.7%) and 2 cases of LRH (20%). No mutations were detected in T-NHL and NLPHL (P < 0.05). There were no significant differences in incidences of BCL-6 gene mutations between nodal and extranodal DLBCL (P > 0.05). All mutations were base substitutions and the frequency of single-base change was 0.14 x 10(-2)/bp approximately 0.68 x 10(-2)/bp.

CONCLUSIONSMutations of the 5'non-coding region of BCL-6 gene may be involved in the pathogenesis and progression of B-NHL. Molecular demonstration of such mutations may provide a marker of lymphomas derived from the germinal center-related B cells.

OBJECTIVETo investigate bcl-6 protein expression and gene rearrangement patterns in diffuse large B-cell lymphoma (DLBCL) and their clinicopathologic significance.

METHODSImmunohistochemical studies for bcl-6 and CD10 proteins were performed on 51 cases of DLBCL paraffin-embedded tissues (including 22 nodal samples and 29 extranodal samples) and 10 cases of reactive lymphoid hyperplasia (RLH) paraffin-embedded tissues. Interphase fluorescence in-situ hybridization (FISH) with dual color breakapart probe was also used to identify rearrangement of bcl-6 gene in 32 cases of nodal DLBCL tissues (including 22 paraffin-embedded samples and 10 fresh samples) and 5 cases of RLH paraffin-embedded tissues.

RESULTS(1) The rates of bcl-6 protein expression in nodal DLBCL, extranodal DLBCL and RLH were 72.7% (16/22), 75.9% (22/29) and 100.0% (10/10) respectively. The rates of CD10 expression were 40.9% (9/22), 41.4% (12/29) and 100.0% (10/10) respectively. All lymphoma samples which expressed CD10 also showed co-expression of bcl-6 protein. (2) The co-expression of bcl-6 and CD10 was observed in 40.9% (9/22) nodal DLBCL and 41.4% (12/29) extranodal DLBCL. Low clinical stage (stage I and II) was more frequently observed in cases with co-expression of bcl-6 and CD10 (P < 0.05). (3) The rates of bcl-6 gene rearrangement in nodal DLBCL was 28.1% (9/32), with 27.3% (6/22) in paraffin-embedded tissues and 30.0% (3/10) in fresh tissues. There was no statistically significant difference found between the two groups (P > 0.05). Bcl-6 gene rearrangement was not found in all the 5 cases of RLH, and there was a significant difference between RLH and DLBCL (P < 0.05).

CONCLUSIONSThe rate of bcl-6 protein expression is high in DLBCL cases, and the detection of bcl-6 and CD10 protein co-expression may help in the diagnosis and differential diagnosis of DLBCL. Those DLBCL cases with co-expression of bcl-6 and CD10 may also have a better prognostic implication. On the other hand, bcl-6 gene rearrangement can be identified by interphase FISH with dual color breakapart probe in both paraffin-embedded and fresh lymphoma tissues.

OBJECTIVETo clarify three-grade criteria of curative resection for primary liver cancer (PLC) and evaluate their clinical significance.

METHODSCriteria of curative resection of PLC were summed up to three grades. Grade I: complete removal of all gross tumors with no residual tumor at the excision margin. Grade II: on the basis of Grade I, there was no extrahepatic metastasis, no hilar lymph node metastasis, no tumor thrombus in the main trunks and their primary tributaries of the portal vein, common hepatic duct, hepatic vein and vena cava inferior, and the tumor was not more than two in number. Grade III: in addition to the above criteria, AFP dropped to normal level (in patients with elevated AFP before surgery) within 2 months after operation, and no residual tumor upon diagnostic imaging. A total of 354 cases with PLC who had their liver resected was reviewed. Patients in each grade were divided into two portions depending on whether the treatment was curative or palliative.

RESULTSThe survival of patients receiving curative treatment was better than those receiving palliative treatment (P < 0.01). This was true for patients whose treatment belonged to anyone of the three-grade criteria. The survival was improved along with the promotion of curative criteria used. The 5-year survival rate of Grade I, II and III patients undergone curative resection was 43.2%, 51.2% and 64.4%, respectively (P < 0.01).

CONCLUSION1. The three-grade criteria may be used for judging the radicality of tumor resection for PLC. 2. The more stringent the criteria used, the better the survival would be. 3. Adopting high-grade criteria to select cases, to guide operation and postoperative follow-up would improve the results of liver resection for PLC.

OBJECTIVETo review the clinical features and therapeutic experience in children with plastic bronchitis.

METHODSFourteen children with plastic bronchitis were reviewed retrospectively, 12 of which were under two years old. The clinical features are characterized by sudden onset, episodes of profound hypoxia and respiratory tract obstruction. SaO2 was between 0.70 and 0.80 even with mask oxygen inhalation. Eight cases were pyretic, 4 cases expectorated jel-like bronchial casts. The chest X-ray picture showed patchy consolidation or atelectasis unilaterally (10 cases) or bilaterally (2 cases). Pulmonary marking thickening and patchy shadow were observed in 2 cases. Twelve cases underwent rigid bronchoscopy and the bronchial casts were removed. Two cases underwent endotracheal intubation.

RESULTSEight cases of 12 children received therapeutic bronchoscopy were cured. Other 4 cases had second therapeutic bronchoscopy and bronchial casts were removed again in 3 cases, one died from pulmonary hemorrhage. Two cases who underwent endotracheal intubation died from the multiple organ failure (MOF). Pathologic results showed:the bronchial casts were composed mainly of mucus and fibrin, inflammatory cell infiltrate were observed in 6 cases (Type 1, inflammatory), no cellular infiltrate occurred in 8 cases (Type 2, acellular).

CONCLUSIONSPlastic bronchitis is a severe and dangerous disease. The branching plastic casts may obstruct part or the entire tracheobronchial, causing respiratory failure. Bronchoscopy and pathologic examination are essential for it's diagnosis and treatment.
