Three butylphthalide derivatives were isolated from the Rhizome of Ligusticum chuanxiong using a series of isolation and purification approaches including macroporous resin, ODS-A column, Sephadex LH-20 and preparative HPLC. These structures were elucidated based on extensive spectroscopic data (UV, IR, HR-ESI-MS and NMR) and identified as (3Z,3aE)-(6R,7R,2'S)-6-hydroxy-7-(2-carboxyl-2-hydroxyethylthio)-3-(2-hydroxybutylidene)-4,5,6,7-tetrahydro-phthalide (1), (3Z,3aZ)-3-butylidene-6,7-dihydroxy-4,5,6,7-tetrahydro-phthalide 7-O-α-D-glucopyranosyl-(1→2)-β-D-fructo-furanoside (2) and 3-(3-β-D-glucopyranosyloxy-butylidene)-7-hydroxy-phthalide (3).

ObjectiveTo explore the effect of estrogen on osteoblast apoptosis induced by serum hungry in vitro.MethodsOsteoblasts of second or third generation from newly born SD rats calvaria were divided randomly into the control group, serum hungry group and serum hungry with estrogen group. Cells of each group were incubated for 24 h, 48 h, 72 h, 5 d, 7 d and 14 d, then labeled using TUNEL staining and examined for morphological characteristics of apoptotic cell under light microscopy after incubated for 72 h. The rates of apoptotic cells of each group were examined with flow cytometry.ResultsThe cells of the control group showed normal appears, the serum hungry group had many cells with purple and blue particles in nuclei, but serum hungry with estrogen group had less such cells. The rate of apoptotic cell significantly increased in serum hungry group and decreased in serum hungry with estrogen group compared with the control group examined with flow cytometry (P<0.05).ConclusionEstrogen can repress osteoblasts apoptosis of rats induced by serum hungry.

Objective To study the clinical characters,the mode of inheritance of osteogenesis Imperfecta in a Chinese Family and effect of bisphosphonate on Osteogenesis Imperfecta.Methods Clinical data of proband and their family members were collected.The family patterns were mapped.clinical features were summarized and analyzed.Results(1)Clinical features:There are sixty members of four generations in the family.20 cases including proband's mother and cousin were diagnosed as having OI type Ⅰ based on clinical manifestations.15 cases of blue sclera,16 cases of dentinogenesis imperfecta,5 cases of hearing loss and 3 cases of fracture.Thyroid cancer and Turner's syndrome was found in Proband's mother and cousin respectively.(2)The genetic map showed that the disease was autosomal dominant inheritance.(3)Treatment:The proband,her mother and her cousin were treated with alendronate for two years.Bone pain relieved and bone mineral density increased significantly,and no fracture occurred so far.Conclusion(1)This OI family was diagnosed as having OI type Ⅰ.The mode of inheritance is autosomal dominant inheritance.(2)Bisphosphonates may be an effective drug for treatment of OI.

Objective To investigate the current situation of the prevention and contml of iodine deficiency disorders(IDD)in Hubei Province,SO as to provide a policy.making basis for controlling work of IDD. Methods Using the method of proportional population sampling(PPS),30 eounties were seiected in Hubei Province.In each selected county,1 primary school was chosen.In every primary school,40 pupil8 aged 8～10 years were selected to examine thyroid size,intelligent quotient(IQ),and salt iodine contents at their home.In the selected pupils,2 boys and 2 girls were chosen to determine their urinary iodine contents in each age grouD.Twenty pupils in the above school and 5 housewives ileal"to this school were tested in health education questionnaire. Results The median of salt iodine was 30.1 mg/kg,and the rate of comsuming qualified iodized salt was 96.2% (1154/1200).The rates ofchild goiter were 6.5%(78/1200)by palpation and 4.1%(49/1200)by B ultrasound.The median of urinary iodine Was 358.4μg/L and mean of the IQ was 105.3±14.4.The rate of qualified scores of both students and housewives Was 25.5%(153/600)、90.7%(136/150).Conclusions The current Bituation of iedine nutrition is good.The goal of eliminating IDD has been achieved in Hubei Province.

AIMTo investigate the effects of bradykinin on voltage-dependent sodium channel currents in rat dorsal root ganglion neurons (DRG).

METHODSWhole-cell patch clamp technique was used to determine sodium channel current.

RESULTSBradykinin at 0.01 - 10.0 micromol/L dose dependently increased the frequency of repetitive firing of DRG. Bradykinin at 0.01 - 10.0 micromol/L dose dependently enhanced the TTX-R sodium current, and had no effect on TTX-S sodium current.

CONCLUSIONMechanism underlying the inflammation induced by bradykinin is related to the TTX-R sodium channel.

OBJECTIVETo study the clinical effect of arthroscopic excision of popliteal cysts through a combined anterior and posterior approach.

METHODSFrom January 2010 to December 2012,20 patients with popliteal cysts were treated with arthroscopic excision. There were 14 males and 6 females, with an average age of 49.5 years old, ranging from 45 to 65 years old. The lump has been found for 4 to 18 months,with a mean time of 12 months. Their mean sagittal diameter was 4.5 cm (ranged from 3 to 7 cm). There were 12 popliteal cysts in the left and 8 popliteal cysts in the right. The main clinical manifestation included lump at popliteal fossa, swelling and pain at knee joint and some extent of dysfunction. All diagnoses were determined according to MRI, which clearly showed the communication of cyst and articular cavity. The cyst was removed under arthroscopy, through the posterior approach and then the intra-articular lesion was treated via the anterior approach. According to Rauschning and Lindgren classification, 2 patients were grade I, 6 patients were grade II, and 12 patients were grade III. The guidelines of Rauschning and Lindgren were used to evaluate the clinical effects.

RESULTSNo complications such as the injury of blood vessel and nerve, or incision infection occurred in all patients. All the patients were followed up, and the duration ranged from 8 to 24 months, with a mean time of 16 months. According to the criteria of Rauschning and Lindgren, there were 14 cases of grade 0, and 6 cases of grade I after operation, which was improved obviously compared with that pre-operation. No cyst reoccurred and the knee joint pain was relieved.

CONCLUSIONTreatment of popliteal cysts with arthroscopic excision through a combined anterior and posterior approach is effective to remove the cyst sac and treat intra-articular diseases simultaneously, resulting in the decrease recurrence rate of cyst.

Chinese medicine pairs (CMP) are specific compatibility with traditional Chinese medicine (TCM) theory as principle, which was formed on basis of effect and treatment theory of TCM. The compatibility of CMP can enhance the effect, or reduce the toxicity. So, compatibility effects of CMP were studied from different pharmacology levels including animals, tissues and organs, cell and molecular levels, their synergy and compatibility attenuation were also evaluated with monomer component-component (group) compatibility-single herb-CMP-formulae as the main line, and the action mechanisms were investigated, all of which can provide scientific basis for the clinical applications of CMP and creation of TCM new drugs.

Objective To investigate the efficacy of warm needling moxibustion plus medication for rheumatoid arthritis.Methods One hundred patients with rheumatoid arthritis were randomly allocated to two groups (treatment and control) by using random number table method, 50 cases each. The treatment group received warm needling moxibustion plus medication as combined therapy and the control group, oral administration of drugs alone. In both groups, treatment was given 10 times as a course, for a total of two courses. The DAS 28 score was recorded and rheumatoid factor (RF) was determined in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 100％ in the treatment group and 86.0％ in the control group; there was a statistically significant difference between the two groups (P<0.05). There were no statistically significant post-treatment differences in DAS 28 score and RF between the two groups (P>0.05). There were statistically significant differences in pre-/post-treatment DAS 28 score difference value and RF difference value in the two groups (P<0.05).Conclusion Warm needling moxibustion plus medication is clinically more effective than oral administration of drugs alone in treating rheumatoid arthritis.
