This study was aimed to carry out pharmacological research on the hemostatic activity and mechanism of Yi medicine Ma-Bu (Paris polyphylla Smith var stenophylla Franch.). One kind of C27 steroidal saponin from P. polyphylla Smith var stenophylla Franch. was isolated and identified as Paris saponin H (PSH). The effect of PSH on the index of bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) of mice were measured. The results showed that PSH have significant hemostatic activity by shortening BT. The effect of PSH on shortening PT and APTT of mouse was not significant. However, the FIB was enhanced significantly after treatment with PSH. It was concluded that PSH had no significant promoting effect on the extrinsic coagulation pathway (ECP) or the intrinsic coagulation pathway (ICP). The enhancement of FIB may be a pathway for the effect of hemostatic activity by PSH.

Objective To study the values of quantitative assessment of extraocular muscles in diagnosing the thyroid associated ophthalmopathy(TAO).Methods The maximum section area,short and long diameters of extraocular muscles on orbital coronal CT were measured and the value of R was calculated in 50 healthy persons and 50 patients with TAO.Results The maximum section areas of 228 extraocular muscles in 50 patients with TAO increased,of them,inferior rectus(30.3%) and mediate rectus muscle(23.2%) were common,followed by superior rectus,lateral rectus and superior oblique muscle.Their maximum section areas(70.21 mm2,56.93 mm2,64.06 mm2,58.51 mm2,20.65 mm2,respectively) and the values of R(0.61,0.55,0.61,0.50,0.52,respectively) were larger than that in healthy group(27.72 mm2,27.07 mm2,26.93 mm2,36.74 mm2,9.42 mm2 respectively in maximum section areas) and(0.41,0.35,0.60,0.34,0.44 in the values of R,respectively).There were statistical significant differents between them.Conclusion The quantitative coronal CT measurement,especially the values of R can assess enlargement of extraocular muscles accurately,which may be helpful in diagnosis of TAO.

Objective To investigate the clinical therapeutic effect of Xuebijing injection for treatment of patients with ventilator-associated pneumonia (VAP).Methods A prospective study was conducted. Forty-eight patients with confirmed diagnosis of VAP requiring mechanical ventilation admitted into intensive care unit (ICU) of Hubei Provincial Hospital of Integrated Traditional Chinese and Western Medicine between May 2013 and September 2014 were enrolled. The patients were randomly divided into observation group (26 cases) and control group (22 cases) by random number table. All patients in both groups received western conventional treatment, and the patients in observation group were treated additionally with 50 mL Xuebijing injection intravenous drip twice a day, and control group received only routine western medicine, the therapeutic course in both groups being 7 days. The changes of white blood cell count (WBC), serum procalcitonin (PCT) levels and the clinical pulmonary infection score (CPIS) were observed, and the clinical therapeutic effect and 28-day prognosis were analyzed in both groups.Results After treatment for 7 days, the WBC, PCT levels and CPIS score were decreased compared with those before treatment in the two groups, and the degree of descent in observation group was more significant than that in the control group [WBC (×109/L): 9.16±1.62 vs. 12.03±2.34, PCT (μg/L): 0.17±0.04 vs. 0.28±0.69, CPIS score: 3.31±0.97 vs. 4.23±1.15, allP < 0.05]. The effective rate of observation group was higher than that of the control group [84.6% (22/26) vs. 54.5% (12/22), P < 0.05], while the 28-day fatality rate in the observation group was lower than that of control group [11.5% (3/26) vs. 36.4% (8/22),P < 0.05].Conclusion The clinical therapeutic effect is good when patients with VAP is treated with addition of Xuebijing injection on the basis of conventional western medicine therapy, as the injection can improve the therapeutic efficacy and reduce the fatality rate.

Objective:To explore the clinical effect of ALTF transfer with cross-limb bridged "Y" shape vascular anastomosis in repair of complex soft tissue defects in calf.Methods:From August 2010 to September 2020, 33 patients(23 males and 10 females) with complex traumatic soft tissue defects in calf were treated. Preoperative angiography and intraoperative exploration confirmed that there was only 1 main vessel remained in the affected calf or the wound surface and the vessel could not be anastomosed with the vascular pedicle of the ALTF. The size of flap were 16 cm × 8 cm to 25 cm × 18 cm. Two patients received bilobed ALTFs. A "Y" shape anastomosis between the artery of ALTF vascular pedicle and the posterior tibial artery of the contralateral lower limbs was made in all 33 patients to establish the blood supply to the transferred free ALTF. The "Y" shape cross-limb bridged blood vessels at the proximal end of the vascular pedicle artery of the flap were embedded at both ends of the cut-off superior ankle posterior tibial artery of the contralateral lower limb. The vein of the flap was anastomosed with the saphenous vein that associates with the posterior tibial artery. The surface of the suspended blood vessel "bridge" was wrapped with a free skin craft, and the lower limbs were fixed in a straight and parallel position with an external fixation frame. The perfused area of the flap was directly sutured or covered with a free skin craft. The vascular bridge was kept for 3 to 6 weeks before being separated. Outpatient follow-up after discharge.Results:All the patients were entered the postoperative follow-up was 13 months to 7 years, in an average of 25 months. Among the 33 flaps, 31 survived completely, except 1 had necrosis and the other 1 had partial necrosis at the distal end of the flap. The flaps received good blood supply, hence with soft texture and satisfactory appearance. Doppler or DSA was performed after the surgery on the posterior tibial artery of the healthy limb, and the vascular pulsation and patency were found normal. Donor sites for the free skin graft healed well.Conclusion:The ALTF transfer with cross-limb bridged "Y" vascular anastomosis is one of the effective techniques and it was employed in the repair of complex defects of calf soft tissue. It solved the tissue that there was only 1 main vessel or even without a suitable vessel could be anastomosed with the pedicle of the flap.

OBJECTIVE: To investigate the effectiveness of Flow-through bridge anterolateral thigh flap transplantation in the treatment of complex calf soft tissue defects. METHODS: The clinical data of the patients with complicated calf soft tissue defects, who were treated with Flow-through bridge anterolateral thigh flap (study group, 23 cases) or bridge anterolateral thigh flap (control group, 23 cases) between January 2008 and January 2022, were retrospectively analyzed. All complex calf soft tissue defects in the two groups were caused by trauma or osteomyelitis, and there was only one major blood vessel in the calf or no blood vessel anastomosed with the grafted skin flap. There was no significant difference between the two groups in general data such as gender, age, etiology, size of leg soft tissue defect, and time from injury to operation ( P>0.05). The lower extremity functional scale (LEFS) was used to evaluate the sufferred lower extremity function of the both groups after operation, and the peripheral blood circulation score of the healthy side was evaluated according to the Chinese Medical Association Hand Surgery Society's functional evaluation standard for replantation of amputated limbs. Weber's quantitative method was used to detect static 2-point discrimination (S2PD) to evaluate peripheral sensation of the healthy side, and the popliteal artery flow velocity, toenail capillary filling time, foot temperature, toe blood oxygen saturation of the healthy side, and the incidence of complications were compared between the two groups. RESULTS: No vascular or nerve injury occurred during operation. All flaps survived, and 1 case of partial flap necrosis occurred in both groups, which healed after free skin grafting. All patients were followed up 6 months to 8 years, with a median time of 26 months. The function of the sufferred limb of the two groups recovered satisfactorily, the blood supply of the flap was good, the texture was soft, and the appearance was fair. The incision in the donor site healed well with a linear scar, and the color of the skin graft area was similar. Only a rectangular scar could be seen in the skin donor area where have a satisfactory appearance. The blood supply of the distal limb of the healthy limb was good, and there was no obvious abnormality in color and skin temperature, and the blood supply of the limb was normal during activity. The popliteal artery flow velocity in the study group was significantly faster than that in the control group at 1 month after the pedicle was cut, and the foot temperature, toe blood oxygen saturation, S2PD, toenail capillary filling time, and peripheral blood circulation score were significantly better than those in the control group ( P<0.05). There were 8 cases of cold feet and 2 cases of numbness on the healthy side in the control group, while only 3 cases of cold feet occurred in the study group. The incidence of complications in the study group (13.04%) was significantly lower than that in the control group (43.47%) ( χ ²=3.860, P=0.049). There was no significant difference in LEFS score between the two groups at 6 months after operation ( P>0.05). CONCLUSION Flow-through bridge anterolateral thigh flap can reduce postoperative complications of healthy feet and reduce the impact of surgery on blood supply and sensation of healthy feet. It is an effective method for repairing complex calf soft tissue defects.
