In this study, the herpetin (HPT) lyophilized liposome was prepared, and its saftey and pharmacodynamics were evaluated. HPT lyophilized liposome was prepared by thin-film ultrasonication method. The lyoprotectant was optimized using particle size and encapsulation efficiency as indexes. Then, the influencing factors of HPT lyophilized liposome were investigated. In addition, preliminary safety and therapy efficiency of HPT lyophilized liposome to liver injury induced by CCl4 in the mice. The optimal lyoprotectant was 5% sucrose plus 5% lactose and the dispersed HPT lyophilized liposomes were spherical with the mean diameter of (107.0 ± 1.2) nm and the mean encapsulation efficiency of (99.7 ± 0.50)%. The lyophilized powder was sensitive to temperature, humidity and illumination. None of hemolysis, hemagglutination and vein irritation was observed after intravenous injection of HPT lyophilized liposomes into rabbits. HPT lyophilized liposome showed obviously therapy efficiency to liver injury induced by CCl4 in the mice. The improvements of ALT, AST and ALP were better than that in HPT free drug. The obtained HPT lyophilized liposome met the standard of CP with fine particle size and encapsulation efficiency after dispersion. The HPT lyophilized liposome showed good safety and enhanced the treatment efficacy of HPT. The HPT lyophilized liposome should be stored in low temperature, sealed condition far away from light.

Incision of the spinal cord (myelotomy) after spinal cord injury (SCI) is a surgical treatment which
is mainly performed within 24 hours after SCI. However, many patients are fi rst seen outside the
established time window of 24 hours. Furthermore, little attention has been given to its effi cacy and
mechanism after 24 hours. In this study, dorsal longitudinal incision of spinal cord on SCI rats was
performed at 72 hours after SCI to remove the liquefi ed necrotic gray matter. The results indicated
that after myelotomy, locomotor function of hindlimbs signifi cantly improved from 21st day after SCI.
There was also increased residual white matter area at the rostral and caudal segments to the injury
center when examined at day 42 after the injury. These results suggested that myelotomy at 72 hours
after injury has protective effect on the spinal cord.

To study the effect of Gegen Qinlian decoction and its major effective components on five hepatic microsomal CYP450 isozymes in rats. The in vitro hepatic microsomal incubation technique was used to co-culture Gegen Qinlian decoction and its major effective components together with each probe substrate. HPLC-MS/MS was used to establish the analytical method for metabolites of the five isoform probe substrates of CYP450 isozymes, detect the linearity among micoromal protein concentration, incubation time and metabolite formation amount. And HPLC-MS/MS was applied to determine the formation rate (V) of corresponding metabolites (acetaminophen, 4-OH-chlorzoxazone, dextrophan, 6-OH-chlorzoxazone and 6β-hydroxytestosterone) specific probe substrates of the five isoform probe substrates of CYP450 isozymes (phenacetin, polbutamide, dextromethorphan, chlorzoxazone, testosterone), in order to determine the activity of each isozyme. The result showed good linearity among acetaminophen, 4-OH-tolbutamide, dextrophan, 6-OH-chlorzoxazone and 6β-hydroxytestosterone, satisfactory precision, stability and average recovery, suggesting the method was feasible. The optimized in vitro microsomal incubation conditions conformed to the requirements in the guideline of drug-drug interaction. Gegen Qinlian decoction showed different degrees of inhibitor effect on 5 CYP450 isoforms (CYP1A2, CYP2C11, CYP2D2, CYP2E1, CYP3A1/2). Its major effective component berberine could inhibit each CYP450 isoform at high concentrations (except for CYP1A2, CYP3A1/2).

Herpetin (HPT) is an active monomer constituent isolated from lignanoid in seeds of Herpetospermum caudigerum. HPT shows inhibitory effects in hepatic injury and HBV-DNA and the replication. In the study, we successfully prepare herpetin liposomes by film dispersion method for the first time. The prescription process was optimized, with the entrapment efficiency as the index. According to the optimized prescription, the mass ratio of HPT: phospholipids: cholesterol was 2.44:78.05: 19.51, the hydration and de-molding process was performed with 0.5% F68 solution at 50 degrees C, and the water-bath ultrasonic time was 20 min. The HPT liposomes prepared by this method showed an average entrapment efficiency of (94.50 +/- 2.15)% and a particle size of (119.2 +/- 10.7) nm, which was consistent with the trial expectations and will lay a solid foundation for the hepatic targeting delivery system in future.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.
METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.
RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).
CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

Although previous studies have shown functional efficacy of myelotomy for the treatment of spinal
cord injury (SCI), the underlying mechanism remained unknown. This study aimed to determine
the relationship between myelotomy-mediated neuroprotection and autophagy following SCI by
evaluating the expression of microtubule-associated protein light chain 3 (LC3-II) and mammalian
target of rapamycin complex 1 (mTORC1). Ninety-nine adult female rats were randomly assigned
to either sham-operated group (SG), model group (MG), or 24 h-myelotomy group (MTG). SCI at
T10 was induced with a New York University impactor, and myelotomy was performed 24 h after
SCI. Functional recovery was evaluated via the open-field test. The protein expression of LC3-II
was analyzed by Western blot, and the mRNA expression of LC3-II and mTORC1 were detected by
real-time quantitative reverse transcriptase polymerase chain reaction. Rats in the MTG exhibited
significantly better performance in the hind limbs compared to those in the MG on day seven and
fourteen post-injury. Myelotomy suppressed the protein and mRNA expression of LC3-II on day three,
seven and fourteen post-injury and increased the mRNA expression of mTORC1 in the MTG on day
three and seven post-injury. The LC3-II protein expression was significantly and negatively correlated
with BBB scores at day seven and fourteen post-injury. These results showed that myelotomy-induced
neuroprotection in a rat model of SCI was likely mediated by inhibition of autophagy by activation
of the mTORC1 signaling pathway

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVETo explore the effect of electroacupuncture therapy for postoperative rehabilitation of total knee replacement of knee osteoarthritis.
METHODSSeventy cases of total knee replacement of knee osteoarthritis were randomly divided into an acupuncture-rehabilitation group and a rehabilitation group, thirty five cases in each group. In acupuncture-rehabilitation group, routine rehabilitation therapy combined with electroacupuncture therapy was applied. The acupoints selection was mainly based on pathological location; Xuehai (SP 10), Liangqiu (ST 34), Dubi (ST 35), Neixiyan (EX-LE 4) and Yanglingquan (GB 34), etc. were selected. In rehabilitation group, routine rehabilitation therapy was applied. The functions of affected knee in both groups were evaluated by artificial total knee replacement scale of the New York Hospital for Special Surgery (HSS), range of motion (ROM) of affected knee, Visual Analogue Scale (VAS) of pain and Manual Muscle Test (MMT) before, and 2, 6 and 12 weeks after surgery.
RESULTSHSS scores in acupuncture-rehabilitation group were markedly higher than those in rehabilitation group in 2, 6 and 12 weeks after surgery (P < 0.05, P < 0.01); VAS scores in acupuncture-rehabilitation group were markedly lower than those in rehabilitation group (P < 0.05, P < 0.01); ROM and MMT in acupuncture-rehabilitation group were little superior to those in rehabilitation group, however, there was no significant difference (all P > 0.05).
CONCLUSIONRehabilitation therapy combined with electroacupuncture can obviously restrain the pain during rehabilitation process for total knee replacement patients, improve the endurance capacity of rehabilitation training and motivation, and obviously promote the recovery of total knee joint function.
