OBJECTIVETo investigate the clinical efficacy of Shexiang Injection (SI) on inflammatory reaction in patients with acute cerebral infarction (ACI).

METHODSForty-two patients with ACI were randomly divided into two groups, 21 in each group. The control group treated with conventional therapy and the SI group treated with conventional therapy plus SI. Besides, 21 healthy people were arranged in the normal group for control. Expression of CD54 of mononuclear cell (MC-CD54) and serum level of soluble vascular cell adhesion molecule-1 (sVCAM-1) were determined and the clinical efficacy was observed dynamically before treatment and on the 7th, 14th day of the course.

RESULTSLevels of MC-CD54 expression and sVCAM-1 in the ACI patients increased obviously (P < 0.01), reached the peak on the 7th day, and declined obviously on the 14th day in both groups, however, the lowering in the SI group was more significant than that in the control group (P < 0.01); and positive correlation was shown between these two indexes (P < 0.01). After treatment, score of neural defect was improved more significantly (P < 0.01), and the markedly effective and curative rate was higher in the SI group than those in the control group (P < 0.05), respectively.

CONCLUSIONSI could inhibit the subsequent inflammatory reaction, and thus improve the clinical efficacy of conventional therapy in treating patients with ACI.

OBJECTIVETo study value of velocity vector imaging (VVI) in assessment of normal left ventricular diastolic function and the corresponding reference values.

METHODSNinety-seven healthy subjects were selected by combined clinical, ultrasound, and NT-proBNP examinations. Using a Siemens Acuson Sequoia C512 echocardiograph, VVI was adopted to examine the myocardial early diastolic velocity (E) of the septal, lateral, anterior, inferior, anterior septum, and posterior wall of the left ventricle at the level of mitral annulus. The images were analyzed for VVI and the mean diastolic velocity (E(m)) and hence the E/E(m) ratio was calculated based on the offline workstation interface.

RESULTSThe reference range of E/E(m) ratio derived from the data of the 97 healthy subjects was (unilateral boundaries with 95% limit) and (1, 22.935), was (1, 22.300) in male subjects and (1, 24.766) in female subjects. The reference E/E(m) range was (0, 22.413) in male subjects under 50 years of age, (1, 24.766) in female subjects under 50 years, (1, 22.300) in male subjects over 50 years, and (1, 24.766) in female subjects over 50 years.

CONCLUSIONVVI is a good method for non-invasive evaluation of the left ventricular diastolic function and provides an accurate and reliable means for clinical assessment of the left ventricular diastolic function.

OBJECTIVETo compare changes of hypothalamus-pituitary-adrenal axis (HPAA) in different rat models of Gan stagnation (GS), Pi deficiency (PD), Gan stagnation Pi deficiency (GSPD) syndromes, and to observe interventional effect of Chaishu Sijun Decoction (CSD, capable of soothing Gan-qi invigorating Pi) on them.

METHODSSeventy Wistar rats were divided into the normal control group (group 1), the GS group (group 2), the PD group (group 3), the GSPD group (group 4), the GS intervention group (group 5), the PD intervention group (group 6), and the GSPD intervention group (group 7) according to random digit table, 10 in each group. Rats in group 1 received no treatment. Rats in group 2 and 5 were modeled by chronic restraint method. Rats in group 3 and 6 were modeled by excess fatigue plus alimentary abstinence method. Rats in group 4 and 7 were modeled by chronic restraint, excess fatigue, and alimentary abstinence method. At the 2nd weekend of modeling, CSD at 2.86 g/kg was fed to rats in group 5, 6, and 7 by gastrogavage for 2 successive weeks. Equal volume of distilled water was given to rats in the rest 4 groups. On the 29th day, rats were killed, adrenal weight weighed, and adrenal index calculated. Levels of plasma and hypothalamus corticotropin-releasing hormone (CRH), plasma and pituitary adrenocorticotrophic hormone (ACTH), and plasma corticosterone (CORT) were determined using radioimmunity.

RESULTSCompared with group 1, adrenal index significantly decreased in group 2, 3, and 4 (P < 0.05). Of them, plasma and hypothalamus CRH, plasma CORT increased significantly in group 2 and 4 (P < 0.05). Besides, plasma and pituitary ACTH increased in group 4 (P < 0.05). Plasma and pituitary ACTH, as well as plasma CORT decreased significantly in group 3 (P < 0.05). Compared with group 2, 3, and 4, adrenal index increased significantly in group 5, 6, and 7 (P < 0.05). Compared with group 2, plasma CORT, hypothalamus CRH, and pituitary ACTH decreased significantly in group 5 (P < 0.05). Compared with group 3, plasma ACTH and CORT increased significantly in group 6 (P < 0.05). Compared with group 4, plasma CRH, ACTH, CORT, hypothalamus CRH, and pituitary ACTH decreased in group 7 (P < 0.05).

CONCLUSIONSThe function of HPA .axis was damaged to varying degrees in rats of the three models in this experiment. Hyperactivity of HPA axis existed in GS syndrome and GSPD syndrome. Impairment of feedback regulation in hypothalamus and pituitary was accompanied in GSPD syndrome. Hypofunction of HPA axis existed in PDS. CSD, capable of soothing Gan-qi invigorating'Pi, showed improvement on disarranged HPAA, but with optimal effect on GSPD syndrome. CSD had higher correlation with GSPD syndrome.

OBJECTIVETo summarize the experience of repair and reconstruction of penile defects as a result of devastating deep burn.

METHODSTwenty-four patients with penile defects in early or late (a half year after wound healed, the same below) stage after burn were involved. Their suspensory ligaments of penis were dissected to lengthen the penis after escharotomy with the necrotic distal part removed. The wounds formed after lengthening were covered with lower abdominal skin flap, scrotal or internal pudendal artery flap. Ten patients underwent surgery within 30 days after burn; the other 14 patients underwent surgery in the late stage. The condition of flaps and complications after surgery were observed. The lengths of penis of patients in flaccid and erection state were measured before surgery and at follow-up period. The sensory function of penile skin, the erectile function of the penis, and sexual intercourse activity of patients were followed up.

RESULTSAll the flaps survived except two, in whom areas of 1.0 cm x 0.5 cm and 1.5 cm x 1.0 cm of necrosis at distal parts were found, and they healed after dressing changes. Patients were followed up for 2 to 5 years. The length of penis in flaccid state was (7.4 +/- 1.6) cm, which was (5.3 +/- 1.4) cm longer than that before surgery (P < 0.01). The length of penis in erection state was (9.7 +/- 1.2) cm. The sensory function of penis recovered gradually about half year after surgery with well preserved erectile function. Except one who did not try to have sexual intercourse again, all the other married patients and their spouses were satisfied or quite satisfied with sexual intercourse activity.

CONCLUSIONSPenis elongation combined with skin flap grafting is a good method for the treatment of penile defects due to devastating deep burn. Suitable length and erectile function of penis can be preserved with this method.

OBJECTIVETo study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele.

METHODSThis study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters.

RESULTSAll the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair.

CONCLUSIONSAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.
