Objective: To explore the correlation between moxibustion sensation and distance of moxa stick and provide reference for clinical practice. Methods: A total of 16 healthy volunteers aged 18-35 years old in college were recruited and given mild moxibustion at Shousanli (LI 10), Zusanli (ST 36), Shenshu (BL 23) and Tianshu (ST 25) with moxa stick, and the occurrence and frequency of moxibustion sensation were recorded at distances of 5 cm, 4 cm, 3 cm and 2 cm. Mild moxibustion scale was used to count the score. Results: Warm was the main moxibustion sensation, burning pain and soreness decreased with the rise of distance; for the same acupoint, score of mild moxibustion scale increased with the decrease of distance; score ranged between 5.5 and 6.5 at distance 3 cm, which was the most comfortable distance for volunteers. Conclusion: The distance of 3 cm is the most comfortable distance in mild moxibustion.

Objective: To explore the beneficial regulatory effect of mild moxibustion from different distances at Zusanli (ST 36) of healthy population on the functions of temperature-related brain regions. Methods: In 20 recruited healthy subjects, the change of the temperature-related brain regions induced by mild moxibustion from different distances at Zusanli (ST 36) was observed by functional magnetic resonance imaging (fMRI). Results: In comparison of the values in amplitude of low-frequency fluctuation (fALFF) during and before moxibustion, it has been found that in moxibustion of 2 cm distance, fALFF value increased in the brain regions of the left anterior cingulated cortex and lateral surrounding cerebral regions, and fALFF value decreased in the cerebral regions of the peripheral cortex of the calcarine fissure; in moxibustion of 3 cm distance, fALFF value increased in the brain regions of the right and medial side and paracingulated gyrus, and fALFF value decreased in the cerebral zone of the left middle temporal gyrus; in moxibustion of 4 cm distance, fALFF value increased in the brain regions of the right and medial and paracingulated gyrus; and in moxibustion of 5 cm distance, fALFF value increased in the brain regions of the left hippocampus. In comparison of the value of regional homogeneity (ReHo), it has been found that in moxibustion of 2 cm distance, ReHo value increased in the cerebral zone of the posterior lobe of the right cerebellum, and ReHo value decreased in the cerebral zone of the right occipital lobe; in moxibustion of 3 cm distance, ReHo value increased in the brain regions of the left cerebellar posterior lobe and left frontal lobe, and ReHo value decreased in the cerebral zone of the right inferior temporal gyrus; in moxibustion of 4 cm distance, ReHo value increased in the brain regions of the right superior frontal gyrus and ReHo value decreased in the brain regions of the right parietal lobe and angular gyrus; in moxibustion of 5 cm distance, ReHo value increased in the cerebral zone of the right frontal lobe and ReHo value decreased in the cerebral zone of the right brainstem. Conclusion: In moxibustion of 3 cm distance, the changes in the brain regions basically conform to the transmission route of body trunk temperature.

Objective To introduce a method of functional reconstruction for total lower lip defects.Methods Six patients with lower lip cancer were treated by surgery from November 2007 to February 2009.The full thickness defects with a size from eighty percent to total lower lip were reconstructed with two triangular mental neurovascular island flaps of chin.The musculocutaneous and mucous flaps with neurovascular pedicles were advanced in a V-Y manner to close the defect and reconstruct the orbicularis oris muscle.Results All flaps survived and no recurrence and complication were observed and showed excellent cosmetic and functional results over 6 months of follow-up.The reconstructed lower lips provided a wide-enough mouth opening,and the sensation of oral mucosa and the muscle function of oral sphincter were preserved.Conclusions The technique of mental neurovascular V-Y advancement island flap can get satisfactory results in both functional and the aesthetic perspects.

ObjectiveTo probe the indication,treatment algorithm,anesthesia method,safety and efficacy ofextracorporealshockwavelithotripsy(ESWL)incombinationwithendoscopicretrograde cholangiopancreatography (ERCP) for pancreatic duct stones.MethodsThe patients with chronic pancreatitis and large pancreatic duct stones ( ＞ 5 mm diameter) and receiving ESWL and ERCP between March and July 2011 in Changhai Hospital were prospective studied.The third generation of extracorporeal shockwave lithotripsy was applied in ESWL,and the localization of stone was determined by X-ray.No more than 5000 shocks were given per session,and ESWL was performed continuously till the calculi were fragmented,and then was cleared by ERCP.ResultsA total of 100 patients underwent ESWL during the 5 months,among whom 84 patients received ERCP treatment and 41 cases failed to deep cannulation (41/84,48.8％ ).Multiple stones were seen in 83 patients.Ninety five patients had radio-opaque stones,two patients had radiolucent calculi,while three patients had both radio-opaque and radiolucent stones.Seventy five percent,14％ and 11％ stones were located in pancreatic head,pancreatic head and body,pancreatic body and tail,respectively.A total of 175 ESWL procedures were performed,43 patients needed 2 or more sessions for successful fragmentation.Anesthesia method was mainly intravenous sedation,accounting for 96％ (168/175).ERCP was successful in 96 patients after ESWL,only 4 patients failed after ESWL. Forty one cases which failed ERCP procedures before ESWL underwent ERCP,and 37 patients (90.2％) achieved successful cannulation.Successful fragmentation ratewas 100％.Complete clearance was achieved in 78 patients,and complication rate of post-ERCP pancreatitis,fever was 1.71％ (n =3 ),0.57％ (n =1 ),and the overall complication rate was 2.28％.Conclusions ESWL is an effective,safe and necessary modality for fragmentation of large PD stones in the management of minimal invasive treatment of chronic pancreatitis.

Objective Clinical data of 19 Chinese patients with 21 hydroxylase deficiency (21OHD) were analyzed to improve the diagnosis and treatment level. Methods Clinical features and laboratory data were collected from 19 patients with 21OHD before and after treatment. Results In male patients, the average age of early appearance of secondary sexual character was (9.3?2.8)yrs, and excess androgen resulted in phallic enlargement. Primary amenorrhea was the most common complaint in female(87.5%), and the signs included a varying degree of labioscrotal fusion and clitoral enlargement. The average level of 17-hydroxy progesterone(17OHP) was (63.42?35.07) ?g/L, and adrenocorticotrophic hormone(ACTH), dehydroepiandrosterone(sodium) sulfate(DHEAS) and testosterone(T) were obviously elevated. CT scan showed bilateral adrenal hyperplasia. The level of 17OHP was significantly decreased after treatment[(63.42?35.07) ?g/L vs (3.15?2.71) ?g/L](P

OBJECTIVE Despite the status of cisplatin (DDP) as a classical chemotherapeutic agent in the treatment of cancer, the development of multidrug resistance often leads to a failure of DDP therapy.Traditional Chinese medicine(TCM)as adjuvant chemotherapy of cancer drugs in China has been widely used in cancer treatment.ZuoJin WAN (ZJW),a TCM formula,was proved reversing drug resistance in gastric cancer,but its exact mechanism was still unclear. METHODS CCK-8 assay was used to detect the cell viability. The levels of proteins and mRNA were evaluated using Western blot and q-PCR. Mitochondrial membrane potential was measured by fl ow cytometry. Depolymerisa-tion of F-actin and translocation of G-actin(gamma-actin)from the cytoplasm to the mitochondria was detected using an immuno fl uorescence assay. RESULTS phosphorylated coflin-1 (p-coflin-1) was overexpressed in the DDP-resistant human gastric cancer cell lines SGC7901/DDP and BGC823/DDP, relative to the respective parent cell lines(SGC7901 and BGC823),and DDP induced the dephosphory-lation of p-coflin-1 in both parent lines but not in the DDP-resistant lines. However, ZJW could induce the dephosphorylation of pcoflin-1 and promote coflin-1 translocation from the cytoplasm into the mito-chondria in both SGC7901/DDP and BGC823/DDP cells. This mitochondrial translocation of coflin-1 was found to induce the conversion of flamentous actin to globular-actin, activate mitochondrial dam-age and calcium overloading, and induce the mitochondrial apoptosis pathway. These effects of ZJW on DDP-resistant human gastric cancer cell lines could be reversed via transfection with coflin-1-specifc siRNA,or treatment with a PP1 and PP2A inhibitor.CONCLUSION ZJW can be used as an inhibitor of chemoresistance in gastric cancer, which may partly be due to dephosphorylation of p-coflin-1 via the activation of PP1 and PP2A.

OBJECTIVETo explore the factors influencing insulin resistance in children with different nutritional status during pubertal development.

METHODSThree hundred children with simple obese aged 7 to 17 years, and 300 normal healthy children and 300 children with malnutrition, matched for age (+/- 3 months) and height (+/- 2 cm), were selected. Fasting serum levels of leptin, insulin, glucose, total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C) were measured for them.

RESULTSLevels of fasting serum insulin in obese children, except for boys at Tanner stage I and girls at Tanner stage II, were higher than those in normal and malnutrition children (P < 0.01). Average serum level of leptin in obese boys and girls at varied Tanner stages was higher than that in normal children, and higher in normal children than that in children with malnutrition (P<0.01). Serum level of TG in obese children [(1.53 +/- 0.13) mmol/L] was higher than that in normal ones [(1.12 +/- 0.10) mmol/L] and in children with malnutrition [(1.03 +/- 0.09) mmol/L]. There was no significant difference in levels of fasting blood glucose and other blood lipids between the three groups of children. Insulin sensitivity decreased with pubertal development and its index reversely correlated with Tanner stage and serum level of leptin (r=-0.27 and -0.36, respectively, P<0.01).

CONCLUSIONObesity (BMI), serum level of leptin and pubertal development were independent risk factors for insulin resistance in children aged 7 to 17 years.

OBJECTIVESTo study the role of leptin in the development boys during their puberty and its relationship with insulin (INS), growth hormone (GH), estradiol (E2) and testosterone (T).

METHODSOne hundred and fifty boys with simple obese aged 7 to 17 years, 150 normal healthy boys and 150 boys with malnutrition matched for age (+/- 3 months) and height (+/- 2 cm) were selected. Serum levels of leptin, INS, GH, E2 and T were measured for them.

RESULTSSerum level of leptin in obese group was significantly higher than that in normal group, and that in normal group was significantly higher than that in malnourished group. In the all three groups, serum level of leptin increased with age first until peak value, then began to decrease, with peak value of 6.96 microg/L at ages of 10-11 y in obese group, 10.25 microg/L at ages of 11-12 y in normal group and 5.08 microg/L at ages of 11-12 y in malnourished group. Serum level of leptin increased steadily from Tanner stages G1 to G2, then began to decrease steadily in G2 to G4. Serum level of leptin increased again in stage G5. Serum level of INS in boys increased steadily with age from 7 to 17 years old. Serum levels of GH, T and E2 in boys began to increase since 10-11 years old. Serum level of leptin positively correlated with serum level of INS and negatively correlated with serum levels of GH and T, but not correlated with serum level of E2.

CONCLUSIONSLeptin may promote pubertal development of boys, but not the determinant factor in triggering and maintaining their pubertal development. Re-increase in level of leptin during stage G5 could inhibit secretion of GH, and signalize the end of puberty in boys.

OBJECTIVETo explore the expression of uncoupling protein-2 mRNA in brown adipose tissue, white adipose tissue and skeletal muscle of diet-induced obesity-resistant (DIO-R) rats.

METHODSFifty male Sprague-Dawley (SD) rats were randomly divided into a control group and a high-fat group and fed with basic diet and high-fat diet respectively for 13 weeks. DIO-R and DIO rats were selected according to their body weight. The change of body weight and the intake of total calorie were observed. Reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the expression of UCP2 mRNA in rat.

RESULTSBody weight and total calorie intake in DIO-R rats (425.1 +/- 27.1) g, (31,693 +/- 946) kJ were significantly lower than those in DIO rats (489.7 +/- 20.5) g, (34,363 +/- 1465) kJ. The peak area of UCP2 mRNA in white adipose tissue in DIO-R rats was 352 +/- 30 and in DIO rats was 101 +/- 12. The peak areas of UCP2 mRNA in skeletal muscle in DIO-R and DIO rats were 130 +/- 15 and 170 +/- 12, respectively. The peak areas of UCP2 mRNA in brown adipose tissue of DIO and DIO-R rats were 124 +/- 14 and 147 +/- 19, respectively.

CONCLUSIONThe expression of UCP2 mRNA in white adipose tissue of DIO-R rats increased significantly. These results suggest that obesity-resistance was associated with a tissue-specific increase in UCP2 expression.
