Objective: To provide anatomic data for management of pterygopalatine fossa lesions via endoscopic transnasal approach. Methods: Fifteen (30 sides) formalin-preserved human skulls were subjected to microsurgical dissection to evaluate the exposure scopes of 3 different endoscopic surgery approaches: endonasal middle meatal transpalatine approach, endonasal middle meatal transantral approach, and endonasal inferior turbinectomy transantral approach. Meanwhile, 20 (40 sides) dry skulls were dissected and the related measurements were obtained. Results: The 3 approaches allowed for different exposure of the pterygopalatine fossa structure. The mean distances from foramen rotundum to anterior nasal spur, superior orbital fissure, and optic canal were (61.86±3.67)mm,(3.56±0.75) mm, and (11.23±1.24) mm, respectively. Conclusion: The 3 endoscopic approaches are safe and effective for resection of different pterygopalatine fossa lesions and foramen rotundum serves as a landmark for safe management of the pterygopalatine fossa.

OBJECTIVETo compare the difference in clinical efficacy on chronic obstructive pulmonary disease (COPD) at stable stage in the patients among the combined therapy of cutting method and western medication (combined therapy), simple cutting method and simple western medication.

METHODSOne hundred and twenty cases of COPD were randomized into three groups, 40 cases in each one. In the cutting method group, for excessive phlegm pattern/syndrome, Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1) and Yuji (LU 10) were selected as the main acupoints, and Lieque (LU 7) and Pianli (LI 6) were as the supplementary acupoints. For the pattern/syndrome of failure to consolidate kidney primary, Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4) and Yuji (LU 10) were selected as main acupoints, and Jueyinshu (BL 14) and Zusanli (ST 36) were as the supplementary acupoint. Three acupoints were selected alternatively in each treatment and the cutting method was applied once every 10 days. Three treatments made one session. Two sessions of treatment were required. In the western medication group, salbutamol sulfate aerosol, one press (200 μg/press) was used each night, as well as salmeterol xinafoate and fluticasone propionate powder for inhalation, one inhalation each night. The treatment of 1 month made one session. Two sessions were required. In the combined therapy group, the cutting method and western medication were applied in combination. The results of clinical symptom score, lung function test, arterial blood gas analysis, degree of inflation as well as clinical efficacy were observed before and after treatment in each group.

RESULTSExcept the degree of lung inflation, the clinical symptom score, indices of lung function test, partial pressure of arterial blood gas (PaO2) and partial pressure of carbon dioxide (PaCO2) were all obviously improved after treatment as compared with those before treatment in each group (all P<0.05). They were apparently improved after treatment in the combined therapy group and the cutting method group as compared with those in the western medication group (all P<0.05). The total effective rate was 77.5% (31/40) in the combined therapy group and was 75.0% (30/40) in the cutting method group, both better than 60.0% (24/40) in the western medication group (both P<0.05).

CONCLUSIONThe simple cutting method based on syndrome differentiation and the combined therapy with western medication achieve the superior efficacy on COPD at stable stage as compared with the simple western medication. The effect mechanism is possibly related to the improvement of bronchial airway function through constant acupoint stimulation.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.

METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.

RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).

CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.

OBJECTIVETo investigate the changing laws of serum high mobility group box 1 protein (HMGB1) in septic rats and intervention effect of Xuebijing on it.

METHODSLipopolysaccharide (LPS) (5 mg/kg BW) was intravenously injected into the tail vein of healthy male Wistar rats to prepare the sepsis rat model. In Experiment 1: 50 Wistar rats were randomly divided into three groups, i.e., the normal group (A, n=10); the LPS model group (B, n=10), the LPS +Xuebijing treatment group (C, n=30). Rats in the C group were further divided into three subgroups, i.e., 2 h before LPS injection (group C1), 2 h after LPS injection (group C2), and 8 h after LPS injection (group C3), 10 in each group. Blood samples were collected from the caudal vein to detect serum HMGB1 levels by Western blot at 4, 12, 24, 48, and 72 h after LPS injection. Experiment 2: 30 Wistar rats were equally divided into the LPS model group (D) and the LPS + Xuebijing treatment group (E), 15 in each group. They were treated as rats in the B group and the C1 group respectively. Five rats were sacrificed at 12, 24, and 48 h after LPS injection in the two groups. Blood as well as the tissue samples were harvested to measure such indices as ALT, AST, Cr, and BUN, as well as pathological changes of liver, lung, and kidney.

RESULTS(1) Compared with the A group, serum HMGB1 levels were higher at various time points in the B group (P < 0.05). Compared with the B group, serum HMGB1 levels at 12,24,48, and 72 h decreased in the C1, C2, and C3 groups. Besides, the decrease was more obvious at 24 h and 48 h.The decrement in the C3 group was less than that in the C1 and C2 groups (P < 0.05). (2) In the D group, ALT, AST, Cr, and BUN were significantly higher than those in the A group and reached the peak at 24 h (P < 0.05). Compared with the E group, AST, Cr, and BUN at 24 and 48 h, and ALT at each time point decreased significantly in the E group (P < 0.05). (3)The results of pathological section of liver, lung, and kidney showed local congestion and hemorrhage, cell edema/necrosis/degeneration, infiltration of inflammatory cells, damage of characteristic structures and so on; particularly serious lesion occurred at 24 and 48 h in the D group. The microscopic lesion was obviously alleviated in the E group than in the D group at corresponding time points.

CONCLUSIONSThe serum HMGB1 levels increased in septic rats, with late occurrence of peak value and longer duration of the high value. HMGB1 played an important role in excessive inflammatory response and multiple organ dysfunction. Xuebijing could reduce the serum levels of HMGB1, improve biochemical parameters, and attenuate severe inflammatory response of liver, lung, and kidney tissues in septic rats. Besides, the earlier use, the better effect obtained.

In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.

ObjectiveTo observe female university students' differences of cognitive mechanism in processing different types of sexual picture from International Affective Picture System (IAPS).MethodsUsing event related potential (ERP),the differences of the amplitudes of N2,P3 and PSW were examined induced by the neutral pictures and different types of erotic pictures.ResultsThe amplitudes of N2 ( (0.99 ±1.69 ) μV) and P3 ( ( 17.27 ± 1.45 ) μV) elicited by heterosexual couple erotic pictures were highest,followed by the male erotic pictures( ( -0.02 ± 1.83 ) μV,( 15.92 ± 1.26 ) μV),and then were the female erotic pictures ( ( -0.22 ± 1.56)μV,( 15.49 ±1.34) μV).There was statistical significance in N2 and P3 between heterosexual couple erotic pictures and female erotic pictures ( P ＜0.05 ).There was no significant difference in PSW component between heterosexual couple erotic pictures( ( 15.22 ± 1.98 ) μV) and female erotic pictures ( ( 14.53 ± 1.75 ) μV ),but the PSW induced by male erotic pictures (( 10.93 ± 2.60 )μV) was significantly smaller than the other sexual pictures (P＜0.05).ConclusionThe level of sexual arousal elicited by explicit heterosexual couple erotic pictures is highest and also the attention maintains longest.

Objective To investigate the mechanism and suppression effect of human cytomegalovirus (HCMV) on proliferation of megakaryocyte progenitors(CFU-Mk)in vitro.Methods Colony forming unit-assay was applied to observe the effect of HCMV-AD 169 strain on CFU-Mk of cord blood. The technique of PCR was used to demonstrate the existence of HCMV-AD 169 DNA in the colony cells of cultured CFU-Mk.Results 1.The number of CFU-Mk colonies in HCMV-infected groups decreased significantly compared with that of control group. The CFU-Mk formation was inhibited significantly after HCMV-AD 169 strain infection.The suppression effect showed a dose-dependent fashion: 46.7 % inhibition with 10 -1of HCMV, 29.7 % with 10 -2 and 14.5 % with 10 -3 in the CFU-Mix assay. The peak of CFU-Mk colonies (d16-18) was not significantly different between control group and experimental groups, but the duration of the CFU-Mk colonies in infected groups was significantly shorter than that in control group.2. HCMV-DNA was positively detected in the colony cells of viral infected group by PCR, while negative in control group.Conclusions HCMV-AD 169 strain may inhibit the differentiation and proliferation of CFU-Mk by infecting the hematopoietic progenitors. HCMV may cause the suppression of hematopoiesis by direct infection, which may be the main reason for HCMV infection associated with thrombocytopenia.
