Connotation of Baimai disease and analysis of compatibility and usage of Baimai Ointment: based on Tibetan medicine theory / 中国中药杂志

Baimai is a complex of structure and function with the characteristics of wide distribution, complex structure, and multi-dimensional functions. Baimai, consisting of the channels in brain, the internal hidden channels connecting the viscera, and the external channels linking the limbs, governs the sensory, motor, and information transmission functions of human. According to Tibetan medicine, Baimai functions via "Long"(Qi) which moves in Baimai. "Long" is rough, light, cold, tiny, hard, and dynamic. The dysfunction of Baimai is manifested as numbness, swelling and pain, stiffness, atrophy, contracture, disability, hyperactivity, etc. The clinical manifestations of Baimai disease are facial paralysis, limb numbness, hemiplegia, contracture and rigidity, pain, opistho-tonos, paralysis, unconsciousness, head tremor, aphasia and tongue stiffness, and other abnormalities in facial consciousness, limb movement, and tactile sensation. Baimai Ointment for external use is used for the treatment of Baimai disease. It is mainly composed of medicinals which are spicy and bitter, warm, soft, mild, heavy, moist, and stable, and thus it is effective for the rough, light, cold, tiny, hard, and dynamic "Long" of Baimai disease. In clinical practice, it is mainly used for musculoskeletal diseases, such as osteoarthritis, scapulohumeral periarthritis, cervical spondylosis, low back pain, myofascitis, and tenosynovitis, nervous system diseases, such as paralysis and shoulder-hand syndrome, and limb stiffness caused by stroke, spastic cerebral palsy, trigeminal neuralgia, and facial neuritis, and limb motor and sensory dysfunction caused by trauma. According to the main symptoms of Baimai disease such as stiffness, rigidity, contraction, numbness, sensory disturbance and pain, clinicians should apply the Baimai Ointment via the inunction treatment of Tibetan medicine and in combination with Huo'ermai therapy and physiotherapy.

Effect of moxibustion at Shenque (CV 8) on immune system in rats with different degrees of exhaustive exercise / 针灸推拿医学（英文版）

Objective:To investigate the effect of moxibustion at Shenque (CV 8) on the immune system in rats with different levels of exhaustive exercise.Methods:Fifty-six male Sprague-Dawley (SD) rats were randomly divided into a blank group (n=8),an exhaustive group (n=24),and a moxibustion group (n=24).The exhaustive group was randomly divided into a 1-time exhaustive group,a 4-time exhaustive group and a 7-time exhaustive group,with 8 rats in each group.According to the treatment time,the moxibustion group was randomly divided into a 1-time moxibustion group,a 4-time moxibustion group and a 7-time moxibustion group,with 8 rats in each group.Rats in the exhaustive groups and the moxibustion groups were subjected to replicating the exhaustive swimming models.Rats in each moxibustion group received mild moxibustion for 15 min immediately after the exhaustive modeling,once every other day.Twenty-four hours after the corresponding exhaustive exercise,the rats in each group were tested for the levels of serum immunoglobulin (Ig) G,IgA,IgM and acid phosphatase (ACP),and the morphological changes of spleen tissues were observed.The level of IgA was detected by immunoturbidimetric assay,and the levels of IgG,IgM and ACP were detected by enzyme-linked immunosorbent assay (ELISA).Results:Compared with the 1-time exhaustive group,swimming time of rats in the 4-time exhaustive group was significantly prolonged (P＜0.01),and swimming time of rats in the 7-time exhaustive group was significantly shortened (P＜0.01).Compared with the 7-time exhaustive group,exhaustive swimming time of rats in the 7-time moxibustion group was significantly prolonged (P＜0.01).Compared with the blank group,the IgG level in the 1-time exhaustive group was significantly decreased (P＜0.01),and the levels of IgG,IgA and IgM in the 4-time exhaustive group and the 7-time exhaustive group were all significantly decreased (P＜0.05 or P＜0.01),while the ACP level was increased significantly (both P＜0.01).Microscopically,the number of splenic corpuscles in the 1-time exhaustive group was reduced;the center of some splenic corpuscles in the 4-time exhaustive group was damaged;the number of splenic corpuscles in the 7-time exhaustive group was reduced,and there was no obvious germinal center.Compared with the 4-time exhaustive group,the IgA level in the 4-time moxibustion group was significantly increased (P＜0.01),and the ACP level was significantly decreased (P＜0.01).Compared with the 7-time exhaustive group,the levels of IgG,IgA and IgM in the 7-time moxibustion group were significantly increased (all P＜0.01),and the ACP level was significantly decreased (P＜0.01).Microscopically,the number of splenic corpuscles in the 1-time moxibustion group was reduced;the center of some splenic corpuscles in the 4-time moxibustion group was damaged together with hyperplasia of some splenic corpuscles;blast cells were proliferated in the center of some splenic corpuscles in the 7-time moxibustion group.Conclusion:Moxibustion at Shenque (CV 8) can improve the levels of igG,igA and igM,reduce the ACP level,repair damaged spleen tissues,and enhance the immunity of the body to some extent in the long-term fatigue rats.

Effect of moxibustion at Shenque (CV 8) on free radical metabolism in rat's hippocampus after different degrees of exhaustive exercise / 针灸推拿医学（英文版）

Objective:To investigate the effect of moxibustion at Shenque (CV 8) on free radical metabolism in rat's hippocampus after different degrees of exhaustive exercise.Methods:A total of 72 male Sprague-Dawley (SD) rats were randomly divided into a normal group (n=8),a model group (n=32) and a moxibustion group (n=32).According to the times of modeling or treatment,the model group was further randomly divided into different subgroups of a 1-time model subgroup,a 4-time model subgroup,a 7-time model subgroup and a 10-time model subgroup (n=8);the moxibustion group was also further randomly divided into different subgroups of a 1-time moxibustion subgroup,a 4-time moxibustion subgroup,a 7-time moxibustion subgroup and a 10-time moxibustion subgroup (n=8).Rats in both model and moxibustion subgroups were subjected to establishing the swimming exhaustive model.Rats in each moxibustion subgroup received mild moxibustion at Shenque (CV 8) for 15 min immediately after modeling,once every other day.The concentration of malic dialdehyde (MDA),as well as the activities of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC) in rat's hippocampus in each group were detected 24 h after the exhaustive exercise.Results:Compared with the 1-time model subgroup,the exhaustive swimming time of rats was significantly prolonged in the 4-time model subgroup (P＜0.01),while it was significantly shortened in the 7-time and 10-time model subgroups (both P＜0.01).Compared with the matched model subgroup,the exhaustive swimming time of rats in the 7-time and 10-time moxibustion subgroups was significantly prolonged (both P＜0.01).Compared with the normal group,the MDA concentration was increased significantly (P＜0.01),and the activities stress response of SOD and T-AOC were increased in the 1-time model subgroup (both P＜0.05);the MDA concentration was increased (all P＜0.01),and the activities of SOD,GSH-Px and T-AOC were decreased differently (P＜0.05 or P＜0.01) in the 4-time,7-time and 10-time model subgroups.Compared with the matched model subgroup,the concentration of MDA was significantly reduced (P＜0.05 or P＜0.01),and the activities of SOD,GSH-Px and T-AOC were significantly increased in the 4-time,7-time and 10-time moxibustion subgroups (all P＜0.01).Conclusion:Moxibustion at Shenque (CV 8) can improve the fatigue status of the body after long-term exhaustive exercise by regulating free radical metabolism in rat's hippocampus.To some extent,this provides an experimental basis for moxibustion at Shenque (CV 8) against exercise-induced fatigue.

Objective To investigate the physiological and psychological status of students during the first long distance voyage of Qi Ji-guang Warship and to explore their correlation. Methods From Sep. 17 to Dec. 7, 2017, Qi Ji-guang Warship was on the first long distance voyage mission. On the 60th day during the voyage, the questionnaire survey was conducted on the students aboard Qi Ji-guang Warship. In all, 150 questionnaires were distributed randomly to respondents. The general information of the students was included in the questionnaire, and the physiological status and psychological status were assessed using Pittsburgh sleep quality index (PSQI) scale, Epworth sleeping scale (ESS), fatigue severity scale (FSS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Results A total of 138 valid questionnaires were returned (response rate 92.0%). Forty-two first voyage students (30.4%) complained of health problems. The proportions of the students with poor sleep quality, moderate or excessive daytime sleepiness, high fatigue levels, anxiety and depression were 11.6% (16/138), 45.7% (63/138), 40.6% (56/138), 18.1% (25/138) and 21.0% (29/138), respectively. The PSQI, ESS and FSS scores of the students with anxiety were significantly higher than those of the students without anxiety (8.40±2.93 vs 6.34±3.10, 11.12±5.03 vs 8.70±4.53 and 38.84±12.41 vs 31.55±11.20, all P<0.05). The SAS score was positively correlated with PSQI, ESS and FSS scores (r=0.301, 0.242 and 0.274, all P<0.01). SDS score was positively correlated with PSQI and FSS scores (r=0.256 and 0.209, both P<0.05). Conclusion During long distance voyage, the students aboard have probabilities of poor sleep quality, sleepiness, fatigue, anxiety or depression. Mental status (anxiety and depression) is closely related to physiological status (sleep quality, sleepiness and fatigue), and exerts certain effect on physiological status. Psychological behavior training should be carried out to improve the tolerance, work efficiency and combat ability of students.

Characterization of diterpenoids in the bark of Pseudolarix kaempferi by HPLC-ESI/MSn / 药学学报

Fragmentation behavior of diterpenoids was investigated by ESI/MSn and the qualitative analysis of diterpenoids in the bark of Pseudolarix kaempferi was performed using high-performance liquid chromatography/ multi-stage mass spectrometry (HPLC-ESI/MSn). The characteristic fragmentation behaviors of the diterpenoids are the cleavages of the lactone ring and C4-O bond. Furthermore, the eliminations of substituent groups at C-18, C-7 and C-8 can also be observed in the MS" (n = 3-4) spectra. For C-4 acetoxy subsititued diterpenoids, [M+Na-60]+ and [M-H-104] are the base peaks of MS2 spectra in the positive and negative ionization modes, respectively. For C-4 hydroxyl subsititued diterpenoids, [M+Na-44]+ and [M-H-62] are the base peaks of MS2 in the positive and negative ionization modes, respectively. For C-18 glucosylated or esterized diterpenoids, [M+Na-44]+ is the base peak of MS2 spectra in positive ionization mode. These fragmentation rules were successfully exploited in the identification of diterpenoids in methanol/water (6:4) extract of P. kaempferi by LC-MS in positive ionization mode. A total of 9 diterpenoids were identified or tentatively characterized, and one of them is reported here for the first time. The described method could be utilized for the sensitive and rapid qualitative analysis of P. kaempferi.

Metabolic pathway and metabolites of pseudolaric acid B / 药学学报

The metabolic profile of pseudolaric acid B (PB) was investigated by using in vivo and in vitro tests. Pseudolaric acid C2 (PC2) was identified as the specific metabolite of PB in plasma, urine, bile and feces using HPLC and HPLC-ESI/MS(n) after both oral and intravenous administration to rats, and almost no prototype was detected in all kinds of samples. The metabolic behaviors of PB orally administered in rats treated with antibiotics to eliminate intestinal microflora were identical with those in untreated rats, demonstrating that the metabolism of PB is independent of intestinal microflora. PB was stable in 48 h respective incubation with artificial gastric juice and artificial intestinal juice, suggesting that neither pepsin nor trypsin is in charge of metabolism of PB, and also demonstrating that PB is stable in both pH environments of gastric tract and intestinal tract. In vitro research on metabolism of PB in rat liver microsomes incubation revealed that little PB was metabolized and that the proposed metabolites were the demethoxy and demethoxydecarboxy products of the prototype. The amount of metabolites was extremely low compared with the prototype, indicating that liver microsomes are not responsible for the metabolism of PB either. PB was gradually metabolized into PC2 during 1 h in whole blood incubation in vitro, and the metabolic process showed dynamically dependent manner with incubation time. Once absorbed into blood, PB was quickly metabolized into PC2, accordingly, little prototype was detected in all kinds of samples. The metabolism was attributed to the rapid hydrolysis of C-19 ester bond by plasma esterase. These results clarified the metabolic pathway of PB for the first time, which was of great significance to identify the in vivo active form and interpret acting mechanism of the active compounds of P. kaempferi.
