The secretion and localization of epididymal specific proteins ESP-1, ESP-2 were systematically studied by the PAGE-western blot and ABC immunocytochemical technique in the epididymis of the rabbit. The results indicated that ESP-1 and ESP-2 represented the rabbit epididymal specific proteins of 42 kd and 20 kd, respectively. They were immunoeytochemically negative in the testis, heart, liver, spleen, lung, kidney and skeletal muscle of the rabbit as well as testis and epididymis of the rat. However, in the rabbit epididymis, except the initial segment ESP-1 and ESP-2 were started to be positive from caput segment. The ESP-1 was displyed in the supranuclear area of the principle cells, while the ESP-2 was distributed evenly in the whole cytoplasm of it. Subsequently, the most heavy positive reaction was demonstrated in the corpus epididymis and the proximal segment of cauda. In contrast of the caput, the stereocilia of principle cells and lumen sperms of the cauda epididymis were positive also. However, in the distal segment of cauda the positive reaction in cytoplasm of principle cells was gradually decreased and became disappeared completely soon, while the stereocilia of it still remained heavy positive even in that of vas deferens. The epithelium of prostate gland and seminal vesicle were negative. These results indicated that both ESP-1 and ESP-2 were secretory proteins produced mainly in the principle cells of the corpus epididymis. After releasing into the lumen, they took part of epididymal fluid and might bind on the sperm to regulate sperm maturation. The possible physiological significance of ESP-1 and ESP-2 was discussed.

In this study, the growth and accumulation of active components of Salvia miltiorrhiza in twenty two experimental sites which crossing through three typical climate zones. The S. miltiorrhiza seedlings with the same genotype were planted in each site in spring, which were cultivated in fields with uniform management during their growing seasons till to harvest. The diterpene ketones (dihydrotanshinone, cryptotanshinone, tanshinone I and tanshinone II(A)) in S. miltiorrhiza root samples were determined by using high-performance liquid chromatography (HPLC) method. The biomass of root (root length, number of root branches, root width and dry weight) was also measured. The results showed that tanshinone II(A) in all samples of each site were higher than the standards required by China Pharmacopoeia. It has been found there is a relationship between root shape and climate change. The correlation analysis between active components and meteorological factors showed that the accumulation of tanshinones were effected by such meteorological factors as average relative humidity from April to October > average vapor pressure from April to October > average temperature difference day and night from April to October > annual average temperature and so on. The correlation analysis between root biomass and meteorological factors exhibited that root shape and accumulation of dry matter were affected by those factors, such as average annual aboveground (0-20 cm) temperature from April to October > annual average temperature > average vapor pressure from April to October > annual active accumulated temperature > annual average temperature > average vapor pressure from April to October. The accumulation of tanshinones and biomass was increased with the decrease of latitude. At the same time, the dry matter and diameter of root decreased if altitude rises. In addition, S. miltiorrhiza required sunlight is not sophisticated, when compared with humid and temperature. To sum up, S. miltiorrhiza can adapt to a variety of climatic conditions and the southern warm humid climate is more conducive to its growth and accumulation of active components.

Objective To investigate the value of endoscopy combined with laparoscopy in the treatment of colorectal polyps and polyp canceration.Methods Different combinations of endoscopic and laparoscopic procedures were employed and the clinical efficacies were compared.Results From January 2004 to September 2006,46 cases with colorectal polyp were treated with endoscopy combined with laparoscopy.Among them,5 cases(10.87%)underwent laparoscopic-assisted endoscopic polypectomy,30(65.22%)endoscopic-assisted laparoscopic resection,6(13.04%)synchronously endoscopic and laparoscopic resection.Five cases were performed further operation after endoscopic polypectomy.According to the pathological findings,21(45.7%)were proved to be polyp canceration,among which 6 were advanced carcinoma,and 3 were found metastasis to the lymph nodes.Among the 41 cases of laparoscopic resection,there was no conversion to an open surgery.Anastomotic leakage was found in 2 cases and anastomotic bleeding in 1.In the 5 cases of laparoscopic-assisted endoscopic polypectomy,no complication was observed.During the period of follow-up(1 to 21 months),no recurrence was detected.Conclusion Endoscopy combined with laparoscopy extends the safety and indications of endoscopic polypectomy,and is minimally invasive to the patients.It is an ideal procedure in the treatment of colorectal polyps and poly carceration.

OBJECTIVETo investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.

METHODSClinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.

RESULTSChyle leak occurred in 46 patients(7.7%). The incidence of postoperative chyle leak following right CME hemicolectomy was 13.3%(30/226), significantly higher than that after left CME hemicolectomy (4.4%). On univariate analysis, chyle leak following CME was associated with tumor size(P<0.05), tumor location(P<0.01), and lymph nodes harvested(P<0.01). Multivariate logistic regression revealed that tumor location and lymph nodes harvested were independent risk factors associated with chyle leak following CME(P<0.05).

CONCLUSIONSTumor location and lymph nodes harvested are independent risk factors for chyle leak following complete mesocolic excision for colon cancer. When the drainage output suddenly increases after oral intake resumption, the chyle test of ascitic fluid should be performed for early diagnosis and prompt management.

OBJECTIVENeonatal unconjugated hyperbilirubinemia is one of the most common conditions encountered by the practicing pediatricians. Although it is usually self-limited and benign, the condition is of importance because of the rare instances in which severe hyperbilirubinemia can lead to bilirubin encephalopathy or kernicterus. The uridine diphosphate-glucuronosyl transferase 1A1 (UGT 1A1) gene controls bilirubin conjugation by determining the structure of the enzyme glucuronosyltransferase, which is synthesized in the hepatocyte. In the recent years much has been learned about the relationship between UGT 1A1 gene mutation and neonatal hyperbilirubinemia. This study aimed to investigate the roles of UGT 1A1 gene mutation in the development of neonatal hyperbilirubinemia in Guangxi.

METHODSA total of 73 cases with hyperbilirubinemia and 31 healthy neonates were enrolled. UGT 1A1 G71R genotypes were identified by the (amplification refractory mutation system, ARMS) and direct sequencing method in all the neonates. To analyze the incidence of bilirubin encephalopathy, the peak (total serum bilirubin, TSB) concentration after 72 hours of age, and the possibility of TSB > 20 mg/dl of each group.

RESULTS(1) The frequencies of allele G71R were 0.1915 in this study, 0.2329 in hyperbilirubinemia group vs. 0.097 in healthy groups. The allele gene frequency of G71R in neonatal hyperbilirubinemia was higher than that in the normal group (P < 0.05). (2) Homozygous neonates had higher possibility to develop bilirubin encephalopathy and higher TSB concentration 72 hours after birth (28.57%, 23.12 ± 4.58) than the normal group (0%, 17.68 ± 2.69). The difference between the former two was significant (P < 0.001). (3) The TSB of the 5 neonates was > 20 mg/dl in G71R homozygous type, the odds ratio and 95%CI were 7.955 (1.349, 46.899).

CONCLUSION(1) G71R mutation gene was associated with neonatal jaundice in Guangxi region. (2) The possibility of TSB > 20 mg/dl in G71R homozygous was higher than those of the wild-type. (3) The incidence of bilirubin encephalopathy and TSB concentration after 72 hours of age for neonates who were homozygous to G71R gene were higher than the wild-type.

OBJECTIVETo study the correlation between glucose-6-phosphate dehydrogenase (G-6-PD) activities and three common mutations of G-6-PD gene G1388A, G1376T and A95G and investigate the effects of G-6-PD gene mutations on neonatal jaundice in Nanning, Guangxi.

METHODSOne hundred and twenty-four neonates from Nanning, Guangxi, with hyperbilirubinemia were enrolled. The ARMS-PCR and PCR/REA methods were used to determine G-6-PD gene mutations. G-6-PD activities were measured using the NBT method. The incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth were compared between the neonates with different genotypes and between the G-6-PD mutation and normal groups. The risk of blood serum bilirubin >340 mumol/L was evaluated by logistic regression analysis.

RESULTSOf the 124 cases, gene mutations were found in 37 cases, including G1388A (n=20), G1376T (n=14), A95G (n=4) and G1388A+A95G (n=1). Five cases (25%) showed normal G-6-PD activities in the G1388A gene mutation group and 4 (29%) had normal G-6-PD activities in the G1376T G1388A gene mutation group. All of 4 cases of A95G G1388A gene mutation showed a deficiency of G-6-PD activities. There were no significant differences in the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between the G1388A and G1376T G1388A gene mutation groups. The incidence of acute bilirubin encephalopathy, the peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L in the G-6-PD mutation group were not different from the normal group.

CONCLUSIONSG1388A, G1376T and A95G are common G-6-PD gene mutations in Nanning, Guangxi. The false negative results may be received when the NBT method is used for diagnosis of G-6-PD deficiency. There are similar effects on the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between different gene mutation groups. G-6-PD gene mutations alone may not contribute to the development of acute bilirubin encephalopathy and the changes of peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L.

OBJECTIVETo evaluate the effectiveness of sleeve circumcision of prepuce and coronary sulcus skin in the treatment of patients with multiple condyloma acuminatum (CA) of coronary sulcus of penis.

METHODSIn a randomized clinical control study, 35 patients were randomized to the treatment group and received sleeve circumcision of prepuce and coronary sulcus skin. 34 patients were randomized to the control group, received electric cauterization of verrucae plus the general circumcision. The recurrence of CA was evaluated in follow-up visit within three months after the treatment.

RESULTSThe stitches were taken out 10.2 days after operation in the treatment group, and 8.1 days in the control group. There were no complication in the treatment group, the average healing time of electric cauterization wound was 19.4 days in the control group. There was a statistically significant difference in the recurrence rate of CA between the treatment group and the control group (5.7% vs 26.5% , P <0.05).

CONCLUSIONSThe sleeve circumcision of prepuce and coronary sulcus skin is more effective than electric cauterization of verrucae plus the general circumcision in the treatment of patients with multiple condyloma acuminatum of coronary sulcus of penis.

AIMTo investigate the effect of ciliary neurotrophic factor (CNTF) on the nuclear translocation of protein kinase C (PKC) following NMDA administration in the primary cultured hippocampal neurons.

METHODS(1) PKCGAMMA or PKCepsilon- immunocytochemistry staining method was used after treating neurons with NMDA or CNTF. (2) The gray of the nucleus of the PKC-positive neurons were measured under the image pattern analysis system.

RESULTS(1) After NMDA administration of different concentration and time, Nucleus appear PKCgamma and PKCepsilon activities, especially the 100 micromol/L NMDA 30 min group. (2) The gray of nucleus in CNTF + 500 micromol/L NMDA group is similar to control group.

CONCLUSIONNMDA can induce nuclear translocation of PKC in the primary cultured hippocampal neurons, and CNTF can inhibit the translocation. It suggests that the inhibition of PKC translocation induced by NMDA is one of the important reasons for the neuro-protective effects of CNTF.

Objective To compare the clinical effect of laparoscopic transabdominal preperitoneal prosthesis (TAPP) and Lichtenstein herniorrhaphy in the treatment of inguinal hernia.Methods A total of 224 patients with inguinal hernia were selected from January 2014 to May 2016 in Huanggang Central Hospital.Among the patients,108 patients were treated with laparoscopic TAPP (TAPP group),and 116 patients were treated with Lichtenstein herniorrhaphy (Lichtenstein group).The operation time,intraoperative bleeding volume,postoperative hospitalization time,the first postoperative eating time,the first ambulation time after operation,treatment cost,the incidence of postoperative complications and the recurrence rate of inguinal hernia were compared between the two groups.Results The operation time,the first postoperative feeding time,the first ambulation time after operation,postoperative hospitalization time in the TAPP group were significantly shorter than those in the Lichtenstein group (P ＜ 0.05).The treatment cost in the TAPP group was significantly higher than that in the Lichtenstein group (P ＜ 0.05).There was no significant difference in intraoperative bleeding volume between the two groups (P ＞ 0.05).The incidence of complications in TAPP group and Lichtenstein group was 2.78 ％ (3/108) and 4.31％ (5/116) respectively,there was no significant difference in the incidence of complications between the two groups (x2 =0.381,P ＞ 0.05).There was no recurrence of inguinal hernia in the two groups.Conclusion Compared with Lichtenstein herniorrhaphy,laparoscopic TAPP for inguinal hernia has less trauma,shorter operation time,quicker recovery and higher treatment cost.

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.
