0.25mg/ml of Achyranthes bidentata Saponins( ABS ) in De Jalon's solution usually caused an obvious excitant action in both virgin and pregnant uterine preparations. The uterine excitation was blocked effectively by prior treatment of the preparations with 20?g/ml of indomethacin for 1 h.In the isolated uterine preparations taken from the rats treated with indomethacin, 15 mg/rat orally twice a day for 2 and a half days, the excitant action of ABS was obviously reduced.Treatment of the uterine segments with 0.5?g/ml of chlorpromazine for half an hour also blocked the excitant response. However, treatment of the uterine preparations with 10?g/ml of atropine for 10 min had no abvious effect on the excitant response. The probable mecha-nism of action of ABS was discussed.

Objective To investigate the relationship of pancreatic exocrine function with the pancreatic cancer staging and the size of tumor. Methods N-benzoyl-tryrosyl para-aminobenzoic acid (NBT- PABA) test was used to measure the pancreatic exocrine function of 39 pancreatic cancer patients, 46 chronic pancreatitis patients and 20 normal subjects. In pancreatic cancer group, the relationship of pancreatic exocrine function with the size of tumor (TS) and JPS classification (T factor) was analysed. Results The rate of NBT-PABA excretion in normal subjects, chronic pancreatitis patients were (78.9±15.9)%, (58.6± 19.3)%, respectively; in mild, moderate, severe chronic pancreatitis patients, the values of NBT-PABA were (75.5±23.6)%, (57.9±21.5)%, (45.5±16.7)% ; respectively. The rate of NBT-PABA excretion in pancreatic cancer patients was (47.6±18.3)%, and the rate of NBT-PABA excretion in patients with T3+T4 stage was (42.2±21.70%, and was obviously less than (64.8±11.2)% of T1+T2 stage (P<0.05). Tthe rate of NBT-PABA excretion in patients with TS3+TS4 was (34.8±17.2)%, and was significantly lower than (55.6±23.5)% of TS1+TS2(P<0.05). The rate of NBT-PABA excretion in patients with pancreatic head cancer was (42.5±16.4)%, which was significantly lower than (71.8±9.6)% of the pancreatic body and tail (P<0.05). In the 33 patients with pancreatic head cancer, the rate of NBT-PABA excretion in patients with main pancreatic duct stricture was (54.2±14.1) %, which was significantly higher than (37.6± 14.1)% of patients with main pancreatic duct interruption (P<0.05). There was no significant difference in pancreatic exocrine function between pancreatic cancer and moderate or severe chronic pancreatitis.Conclusions The pancreatic exocrine function was related to the pancreatic cancer staging and the size of tumor to some degree,but it was affected by mass location,and it was also affected by degrees of the pancreatic duct obstruction. The pancreatic exocrine function can not be used to differentiate pancreatic cancer from moderate or severe chronic pancreatitis.

Objective To investigate the expression of Cofilin in alveolar and peripheral blood mononuclear cells in COPD patients and the correlation with the function of phagocytic aspergillus. Methods 20 COPD pa-tients were selected from July 2015 to May 2016 in the outpatient department of respiratory medicine of Zhujiang Hospital of Southern Medical University ,then divided into the experimental group 1(group Aand B in 2011 version of GOLD),group 2(test group C and group D in 2011 version of GOLD),and the healthy control group in 10 people. The AM and MDM in the peripheral bloodwere extracted respectively in the 3 groups by bronchoalveolar lavage and,and the ability of AM and MDM in each group were detected. The expression of Cofilin protein was measured by real-time fluorescence quantitative(qRT-PCR) and Western blotting ,and the differenceswere compared among the three groups. Results The colony numbers of MDM/AM in the 3 groups were 17 ± 3,16 ± 2, 42 ± 3(F = 73.446 ,P < 0.001),and the colony numbers of MDM/AM in the two test groupshad significantly different from the healthy group ,while no significant difference was found in the two test groups. The results of fluorescence quantitative reverse transcription polymerase chain reaction and Western blot analysis showed that the expression of Cofilin in the two test groups was significantly higher than that in the healthy group. Conclusion The decreased function of phagocytic aspergillus in the alveolar and peripheral blood mononuclear cells in COPD patients may relates to the increase of cofilin.

OBJECTIVE:
To investigate curative effect and importance of radiofrequency thermocoagulation onsemilunar ganglion of aged patients with recurrent trigeminal neuralgia.
METHOD:
112 cases with recurrent trigeminal neuralgia were performed with radiofrequency thermocoagulation on semilunar ganglion by puncture through skin under local anesthesia.
RESULT:
The maintaining effective duration in 112 cases was 7.3 ± 1.3 years after primary therapy. After the first thermocoagulation, 89.28% (100/112) patients got the relief from pain immediately, 8 (7.14%) cases also recieved the same effect after twice treatment. However two cases (2.6%) had no effects. The total effective rate was 98.21%. During five follow-up years, VAS scores, dose of carbamazepine and satisfaction were better than those before the treatment. The effective rate was still over 57.5% within three years after the treatment. The recurrent risk increased obviously from 40 months after the treatment by Kaplan-Meier method.
CONCLUSION
Semilunar ganglion of radiofrequency thermocoagulation was an ideal option for old-age patients with trigeminal neuralgia. It can be performed repeatedly.
