OBJECTIVETo observe the distribution of constitution types of Chinese medicine (CM) in patients with osteonecrosis of femoral head (ONFH).

METHODSTotally 130 ONFH patients were recruited. Constitution types of CM were identified in all patients. Distribution features of constitution types of CM in ONFH patients were observed. The differences of distribution in gender, age, single or bilateral hips, course of disease, staging, cause, and region were also analyzed.

RESULTSSeventy patients were of complicated constitutions, while 60 patients were of single constitution. Among the 60 single constitution cases, yang-deficiency constitution [18 (13.9%)], damp-heat constitution [10 (7.7%)], blood-stasis constitution [7 (5.4%)], and qi-deficiency constitution [7 (5.4%)] were mainly distributed. Of the complicated constitutions, yang-deficiency dominated constitution occupied the top ratio [30 (23.1%)], followed by blood-stasis dominated constitution [15 (11.5%)], damp-heat dominated constitution [9 (6.9%)]. By putting them together, yang-deficiency constitution occupied the top constitution of CM [48 (36.9%)], followed by blood-stasis constitution [ 22 (16.9%)] and damp-heat constitution [19 (14.6%)]. The aforesaid three constitutions accounted for 68.5% of the total. There were no statistical distribution differences in gender, age, single or bilateral hips, course of disease, staging, or cause.

CONCLUSIONYang-deficiency constitution, damp-heat constitution, and blood-stasis constitution were liable constitutions of CM in ONFH patients.

The aim of this study was to observe and compare the endogenous circadian rhythm and photoresponse of Clock gene transcription in the suprachiasmatic nucleus (SCN) and pineal gland (PG) of rats. With free access to food and water in special darkrooms, Sprague-Dawley rats were housed under the light regime of constant darkness (DD) for 8 weeks (n=36) or 12 hour-light: 12 hour-dark cycle (LD) for 4 weeks (n=36), respectively. Then, their SCN and PG were dissected out every 4 h in a circadian day, 6 rats at each time (n=6). All animal treatments and sampling during the dark phases were conducted under red dim light (<0.1 lux). The total RNA was extracted from each sample and the semi-quantitative RT-PCR was used to determine the temporal mRNA changes of Clock gene in the SCN and PG at different circadian times (CT) or zeitgeber times (ZT). The grayness ratio of Clock/H3.3 bands was served as the relative estimation of Clock gene expression. The experimental data were analyzed by the Cosine method and the Clock Lab software to fit original results measured at 6 time points and to simulate a circadian rhythmic curve which was then examined for statistical difference by the amplitude F test. The main results are as follows: (1) The mRNA levels of Clock gene in the SCN under DD regime displayed the circadian oscillation (P<0.05). The endogenous rhythmic profiles of Clock gene transcription in the PG were similar to those in the SCN (P>0.05) throughout the day with the peak at the subjective night (CT15 in the SCN or CT18 in the PG) and the trough during the subjective day (CT3 in the SCN or CT6 in the PG). (2) Clock gene transcription in the SCN under LD cycle also showed the circadian oscillation (P<0.05), and the rhythmic profile was anti-phasic to that under DD condition (P<0.05). The amplitude and the mRNA level at the peak of Clock gene transcription in the SCN under LD were significantly increased compared with that under DD (P<0.05), while the value of corresponding rhythmic parameters in the PG under LD were remarkably decreased (P<0.05). (3) Under LD cycle, the circadian profiles of Clock gene transcription induced by light in the PG were quite different from those in the SCN (P<0.05). Their Clock transcription rhythms were anti-phasic, i.e., showing peaks at the light phase ZT10 in the SCN or at the dark time ZT17 in the PG and troughs during the dark time ZT22 in the SCN or during the light phase ZT5 in the PG. The findings of the present study indicate a synchronous endogenous nature of the Clock gene circadian transcriptions in the SCN and PG, and different roles of light regime in modulating the circadian transcriptions of Clock gene in these two central nuclei.

This study was to investigate the circadian rhythms and light responses of Clock gene and arylalkylamine N-acetyltransferase (NAT) gene expressions in the rat pineal gland under the 12 h-light : 12 h-dark cycle condition (LD) and constant darkness (DD). Sprague-Dawley rats housed under the light regime of LD (n=36) for 4 weeks and of DD (n=36) for 8 weeks were sampled for the pineal gland once a group (n=6) every 4 h in a circadian day. The total RNA was extracted from each sample and the semiquantitative reverse transcription polymerase chain reaction (RT-PCR) was used to determine the temporal changes in mRNA levels of Clock and NAT genes during different circadian times or zeitgeber times. The data were analysed by the cosine function software, Clock Lab software and the amplitude F test was used to reveal the circadian rhythm. The main results obtained are as follows. (1) In DD or LD condition, both of Clock and NAT genes mRNA levels in the pineal gland showed robust circadian oscillation (P< 0.05) with the peak at the subjective night or at night-time. (2) In comparison with DD regime, the amplitudes and the mRNA levels at peaks of Clock and NAT genes expressions in LD in the pineal gland were significantly reduced (P< 0.05). (3) In DD or LD condition, the circadian expressions of NAT gene were similar in pattern to those of Clock gene in the pineal gland (P> 0.05). These findings suggest that the expressions of Clock and NAT genes in the pineal gland not only show remarkably synchronous endogenous circadian rhythmic changes, but also response to the ambient light signal in a reduced manner.

OBJECTIVETo evaluate the effect of the combined use of Shenmai Injection (SMI) and enteral nutrition on postoperative fatigue syndrome (POFS) in patients with gastric cancer (GC).

METHODSFifty-eight GC patients were randomized into the parenteral nutrition group (PNG, 19 cases), enteral nutrition group (ENG, 19 cases) and combined treatment group (CTG, 20 cases). The post-operative recovery in patients was observed; patients' conditions of fatigue, mood and sleep were evaluated respectively by visual analogue scale of fatigue, profile of mood states (POMS) and Pittsburgh sleep quality index (PSQI). Meanwhile, nutritional variables, such as serum contents of total protein, albumin, pre-albumin, were measured at different time points: before operation (d0) and the 1st, 5th, and 9th day (d1, d5 and d9) after operation. Immune variables such as subsets of lymphocytes (CD3, CD4, CD8), serum immunoglobulins (IgG, IgM, IgA) were also determined.

RESULTSConditions of recovery, POMS and PSQI were better and the postoperative fatigue reduced more significantly in CTG than those in the other two groups (P < 0.05). On d9, levels of pre-albumin, CD3, CD4, CD4/CD8 in CTG were significantly higher than those in the PNG and ENG (P < 0.05), meantime, levels of albumin and IgA were higher in CTG than those in PNG (P < 0.05).

CONCLUSIONCombined treatment of SMI and enteral nutrition can regulate mood and sleep to some extents, and reduce the postoperative fatigue through improving nutritional status and immune function, thus speeding up the recovery of patients.
