Chinese Journal of Pathophysiology 1989;0(05):-
Head irradiation with 10 Gy X-rays was given to adrenalectomized male rats in the present study to observe the changes of serum LH, FSH and testosterone (TS) levels and testcular cAMP content. The results showed that the function of pituitary-gonad axis decreased in the adrenalectomized male rats. The levels of serum LH and FSH were lower, (P0.05). The changes might be related to the interaction of both hypothalamic CRF and GnRH neurons. Both the serum TS level (P

Objective To investigate laparoscopic-guided selective portal vein ligation in the two-stage hepatectomy for patients with primary hepatocellular carcinoma (HCC).Methods Twenty-three patients with HCC who were not suitable for one-stage hepatectomy were admitted to the Sichuan Provincial People's Hospital from March 2009 to February 2012.Their clinical data were retrospectively analyzed.Laparoscopic-guided selective portal vein ligation was firstly performed,dynamic changes of hepatic volume and predicted volume of liver to be resected were detected by computed tomography.Two-stage open hepatectomy was performed after assessment of resectability of HCC.All data were analyzed using the analysis of variance or q test.Results Laparoscopic-guided selective portal vein ligation was successfully performed on 22 patients (2 patients received concomitant cholecystectomy because the right branch of portal vein was difficult to expose),1 patient was converted to open surgery because of hemorrhage during portal vein separation.Three patients with multiple lesions received transcatheter arterial chemoembolization at 1 week after selective portal vein ligation.Dull pain in the hepatic region,low fever,nausea and vomiting were observed in the 23 patients,while no severe complications including peritoneal hemorrhage,bile leakage,hepatapostema was observed.The levels of aspartate aminotransferase,alanine aminotransferase and total bilirubin were back to normal at 1 week after the surgery.The right liver volume at postoperative week 3 was (590 ± 154)cm3,which was significantly smaller than (698 ± 135)cm3 before surgery.Compared with right liver volume at postoperative week 1,2,3,the right liver volume before operation was significantly smaller (F=15.62,P <0.05).The left hepatic volume at postoperative week 3 was (408 ± 149)cm3,which was significantly bigger than (331 ± 68)cm3 before operation.The left liver volume before operation was significantly different from those at postoperative week 1,2,3 (F =17.48,P < 0.05).The predicted ratio of liver to be resected was 60% ± 18% at postoperative week 3,which was significantly smaller than 67% ± 15% before operation (F =12.35,P < 0.05).Two patients with insufficient hyperplasia of offside liver,2 patients with intrahepatic metastasis at postoperative week 3,2 patients were lost to follow up and 3 patients gave up hepatectomy,14 patients received hepatectomy at 2-4 weeks after laparoscopic-guided selective portal vein ligation.The resection rate was 60.9% (14/23).There were 2 patients received extended right hepatectomy,8 received right hepatectomy,4 received non-anatomical hepatectomy.All the 14 patients recovered well,and no hepatic failure,severe peritoneal effusion and infection was observed.Conclusion Laparoscopic-guided selective portal vein ligation is easy to perform,and it extends the indication of hepatectomy,increases the safety of two-stage hepatectomy.

In order to solve the problems of erratic drug absorption and low bioavailability after oral administration for poorly-water soluble drugs due to low solubility, a series of novel pharmaceutical dosage forms as solid dispersion, liposome, microemulsion, vesicle, cyclodextrin inclusion complexes and drug nanocrystal have been developed in recent years. Among which drug nanocrystal attracts more attentions for its simpler preparation method, higher drug loading and easier manufacturing technology in the design of dosage forms suitable for different administration routes. In this paper, the nanocrystals of the poorly-water soluble drugs prepared based on bottom-up and top-down technologies were introduced. The characteristics and applications of the nanocrystal-based dosage forms as suspension, tablet and capsule were also introduced and carefully evaluated with the focus on their pharmacokinetics, pharmacodynamics and tissue targeted drug distribution after delivery by oral administration, intravenous injection and pulmonary inhalation. The advantages of drug nanocrystals in their therapeutics effects over the bulk drugs were discussed together with the inherent mechanism. Finally, the problems existing in basic research and scaled-up manufacture of drug nanocrystal as well as the possible ways of solution were listed out so as to make the nanocrystal-based preparations exert their maximum therapeutic effect after clinical application.

Objective To observe the effects of electroacupuncture on genu recurvatum after stroke. Methods 80 stroke patients with genu recurvatum were randomly assigned to treatment group (n=40) and control group (n=40). The control group accepted routine rehabilitation, and the treatment group accepted electroacupuncture at Yanglingquan (GB34), Futu (ST32), Weizhong (BL40), Chengshan (BL57) and Zusanli (ST36) in addition, for 30 days. The incidence of effectiveness was compared between groups. All the patients were assessed with range of motion (ROM) of knee and Fugl-Meyer Assessment of lower limbs (FMA) before and after treatment. Results The incidence of effectiveness was 72.5% in the treatment group, which was more than 55% in the control group (P<0.05). The ROM and score of FMA improved more in the treatment group than in the control group (P<0.05). Conclusion The electroacupuncture can promote the recovery of genu recurvatum after stroke.
