To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

Objective To evaluate the protective effect of astragaloside Ⅳ against ultraviolet B (UVB)-induced photodamage to human HaCaT keratinocytes,and to investigate its mechanisms.Methods Culturedimmortalized human HaCaT keratinocytes were divided into four groups:blank control group receiving untreated,UVB group irradiated with 50 mJ/cm2 UVB,astragaloside Ⅳ group treated with astragaloside Ⅳ,UVB + astragalosideⅣ group treated with astragaloside Ⅳ for 24 hours before and after 50 mJ/cm2 of UVB radiation.The concentration ofastragaloside Ⅳ ranged from 10 to 200 mg/L in cell proliferation assay,and according to the results of proliferationassay,20 mg/L was determined as the optimal concentration in the other assays.At 24 hours after UVB radiation,cellcounting kit-8 (CCK8) assay was performed to evaluate cellular proliferative activity,flow cytometry to determineintracellular reactive oxygen species (ROS) levels,and Western blot to measure the expression levels of p53,p38,matrix metalloproteinase-9 (MMP-9) and high mobility group Al (HMGA-1) protein in HaCaT cells.ResultsCompared with the control group,astragaloside Ⅳ at 10 and 20 mg/L had no inhibitory effect (F =1.32,P ＞ 0.05),while astragaloside Ⅳ at 50,100 and 200 mg/L showed significantly inhibitory effect (F =20.20,P ＜ 0.05),on theproliferation of HaCaT cells.In addition,cellular proliferative activity in the UVB group was significantly lower thanthat in the control group (F =99.00,P ＜ 0.01).Compared with the UVB group,cellular proliferative activityincreased to different degrees in HaCaT cells treated with both UVB and astragaloside Ⅳ of 10-200 mg/L (F =19.08,P ＜ 0.01),with the strongest increase observed in those treated with UVB and astragaloside Ⅳ of 20 mg/L.Further experiments revealed reduced intracellular ROS levels in the UVB + astragaloside Ⅳ (20 mg/L) groupcompared with the UVB group (t =21.12,P ＜ 0.01).Western blot assay showed that the expression levels of p53,p38,MMP-9 and HMGA-1 protein were significantly higher in the UVB group than in the control group (all P ＜0.01),but significantly lower in the UVB + astragaloside Ⅳ (20 mg/L) group than in the UVB group (all P ＜ 0.01).Conclusion Astragaloside Ⅳ can effectively protect keratinocytes from UVB-induced photodamage.

Objective To investigate the value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of tuberculous mesenteric lymphadenitis by analyzing its enhancement pattern. Methods The conventional ultrasound and contrast-enhanced ultrasound images of 62 patients with tuberculous mesenteric lymphadenitis confirmed by needle core biopsy or surgery were retrospectively analyzed. The location, size, shape, internal echo and posterior enhancement of mesenteric lymph nodes were recorded. All cases were divided into two groups:the maximum diameter of the lymph node≤20 mm and the maximum diameter of the lymph node >20 mm, and the patterns of enhancement in two groups were analyzed. Results The conventional ultrasound of 62 cases with tuberculous mesenteric lymph nodes showed enlargement. And the echogenicity was hypoechoic or heterogeneity, containing punctate or clusters of calcification in 19 cases (30.6%). After CEUS, there were three forms of enhancements:rim enhancement in 29 cases (46.8%);inhomogeneous enhancement in 21cases (33.9%);non-enhancement in 12 cases (19.3%). Rim enhancement was more common in the≤20 mm group, while inhomogeneous enhancement was more common in the lymph nodes>20 mm. There was statistically significant difference of the enhancement type between the≤20 mm group and the>20 mm group (χ2=6.782, P=0.034). Conclusions Most of tuberculous mesenteric lymph nodes showed rim and inhomogeneous enhancement in CEUS, and the sizes of mesenteric lymph node tuberculosis influenced the CEUS enhancement patterns. CEUS may provide useful information for the diagnosis of the tuberculous mesenteric lymph node.

Objective To compare the effect of injection with botulinum toxin type A (BTX-A) before serial casting with BTX-A injection alone for the treatment of spastic equinus in children with cerebral palsy (CP).Methods Sixty patients were divided into an experimental group and a control group with 30 patients in each.Those io the experimental group received a BTX-A injection followed by serial casting,while the controls received BTX-A only.Before treatment and 1 month,3 months and 6 months after treatment,the dorsiflexion range of motion (ROM)of the ankle recorded while the knee in flexion and extension were measured,and gait was evaluated with an observational gait scale.Results Before treatment there was no significant inter-group difference in any of the 3 outcome measures.At 1 montb,3 months and 6 months after treatment,there were significant inter-group differences in all 3 measures,and also significant differences compared with before treatment in both groups.Conclusion Lower muscle tone,greater ankle mobility and better gait patterns can be promoted in CP children with spastic equinus using serial casting combined with BTX-A injection.The improvements may last longer than those after BTX-A injection alone.

The study is to report the establishment of a method of screening the antitumor compounds based on the dynamic bio-response profile of cells to make up for the shortages of conventional end-point tests such as tedious operation and low sensitivity. Based on the principle of electric impedance of cells, the real-time cell electronic sensing (RT-CES) system was used to monitor the effect of epirubicin (EPI), cisplatinum (DDP) and carboplatin (CBP) on the growth of HepG2 cells, with the cell index (CI), half maximal inhibitory concentration (IC50) and detachment curve as evaluation indexes. Meanwhile, cell counting kit-8 (CCK-8) and microscopy were applied for verification. The results showed that CI curve could sensitively real-time profile the inhibitory effect of model drugs on HepG2 cells. The IC50 of EPI, DDP and CBP were 0.53 +/- 0.04, 9.79 +/- 0.26 and 597.00 +/- 3.79 microg x mL(-1), respectively. What's more, the significant differences of detachment curves of the three drugs indicated that their functional mechanisms might be different, this is consistent with the literature. The RT-CES system with non-invasive, label-free and real-time characteristics could be used to monitor the bio-response profile of the three drugs to HepG2 cells, allowing to qualitatively and quantitatively distinguish the antitumor activities of the three drugs, and could be a complementary method for the present screening of antitumor compounds.

We report a case of pityriasis versicolor atrophicans in a 20-year-old woman who presented with chronic multiple brownish atrophic macules and patches on chest and back. The lesions had developed six years ago and the patient had used topical medication including steroid ointments for the last two years prior to visiting our clinic. KOH examination was positive, so skin biopsy was performed and the diagnosis of pityriasis versicolor atrophicans was made. Since our patient had applied topical steroids for some time, it was difficult to rule out steroid-induced atrophy in a common tinea versicolor. Also, differential diagnosis was performed with respect to other skin diseases manifesting with cutaneous atrophy including anetoderma.
